Ultrastructural localization of cell junctional components (desmoglein, plakoglobin, E-cadherin, and beta-catenin) in Hailey-Hailey disease, Darier's disease, and pemphigus vulgaris.

The distribution of desmoglein, plakoglobin, E-cadherin, and beta-catenin in the peri-lesional and lesional skin of Hailey-Hailey disease, Darier's disease, and pemphigus vulgaris was examined by immunoelectron microscopy. In the peri-lesional skin, the immunolabeling of these desmosomal components was localized to desmosomes. Adherens junction-associated E-cadherin and beta-catenin were at the cell periphery, excluding desmosomes. The labeling pattern was similar among these diseases, but the labeling intensity particularly that of plakoglobin in Hailey-Hailey disease and Darier's disease, was less than that of normal controls, suggesting that these glycoproteins are quantitatively less concentrated in the normal epidermis of these inherited diseases. In the acantholytic cells of Hailey-Hailey disease and Darier's disease the immunolabeling of the components of desmosomes was diffusely distributed in the cytoplasms, whereas that of adherensjunction was mostly at the cell periphery and partly diffusely in the cytoplasm. In contrast, desmosomes of detaching keratinocytes in pemphigus vulgaris still showed the labeling of desmoglein and plakoglobin. These findings suggest that the inherited acantholytic diseases, i.e., Hailey-Hailey disease and Darier's disease have a different pathogenesis from that of autoimmune acantholysis in pemphigus vulgaris: The intracellular components of desmosomes may primarily be disrupted in the genetic acantholytic diseases in the initial stages of acantholysis. Several unsolved questions in the previous light microscopic immunofluorescence studies using the same antibodies are now answered: 1) the diffusion of desmosomal proteins is not due to the internalization of desmosomes, 2) intracellular components of adherens junction are also finally dissolved, 3) diffuse cytoplasmic immunofluorescence patterns of desmosomal components could be explained by immunoelectron microscopy as those attached to cell membrane and trapped in tonofilament aggregates.

[Linear Darier disease].

Darier disease is a genodermatosis with a pattern of autosomal dominant inheritance, which occasionally presents by following a linear or segmental pattern. We present the case of a 22-year-old woman who had presented for three years with small, linearly distributed, yellowish-brown papules on the right lower extremity, with no other skin, mucous membrane or appendage involvement. She had no personal or family history of any interest. Histologically, suprabasal acantholysis and abundant dyskeratotic cells were seen. All of this data led to the diagnosis of linear Darier disease.

P160L mutation in the Ca(2+) ATPase 2A domain in a patient with severe Darier disease.

Darier disease (DD) is caused by mutations of the ATP2A2 gene, which encodes the sarco/endoplasmic reticulum Ca(2+)-ATPase isoform 2 (SERCA2). The mutations affect protein expression, degradation and activity. We report a patient with severe sporadic DD, who did not respond adequately to repeated courses of orally administered acitretin and isotretinoin. He was found to harbor the missense P160L mutation of the ATP2A2 gene in a heterozygous state in the A domain of SERCA2 and polymorphism in intron 18 (2741 + 54 G --> A). The A domain plays a key role in translocation of Ca(2+) from cytoplasm to endoplasmic reticulum lumen, thus establishing a low intracellular Ca(2+) concentration.

Mutations in ATP2A2, encoding a Ca2+ pump, cause Darier disease.

Darier disease (DD) is an autosomal-dominant skin disorder characterized by loss of adhesion between epidermal cells (acantholysis) and abnormal keratinization. Recently we constructed a 2.4-Mb, P1-derived artificial chromosome contig spanning the DD candidate region on chromosome 12q23-24.1. After screening several genes that mapped to this region, we identified mutations in the ATP2A2 gene, which encodes the sarco/endoplasmic reticulum Ca2(+)-ATPase type 2 isoform (SERCA2) and is highly expressed in keratinocytes. Thirteen mutations were identified, including frameshift deletions, in-frame deletions or insertions, splice-site mutations and non-conservative missense mutations in functional domains. Our results demonstrate that mutations in ATP2A2 cause DD and disclose a role for this pump in a Ca(2+)-signalling pathway regulating cell-to-cell adhesion and differentiation of the epidermis.

Keratinocytes cultured from patients with Hailey-Hailey disease and Darier disease display distinct patterns of calcium regulation.

BACKGROUND: Hailey-Hailey disease (HHD) (OMIM 16960) and Darier disease (DD) (OMIM 124200) are dominantly inherited acantholytic skin diseases, respectively, caused by mutations in the genes encoding the Golgi secretory pathway Ca2+-ATPase (SPCA1, ATP2C1) and the sarco/endoplasmic reticulum Ca2+-ATPase type 2 (SERCA2, ATP2A2) genes. OBJECTIVES: To investigate calcium regulation in keratinocytes cultured from patients with HHD and DD by measuring intracellular calcium resting levels and the cellular responses to ATP and thapsigargin. METHODS: The study was carried out using keratinocyte cultures established from four patients with HHD and four with DD. Calcium concentrations were measured with fluorescence ratio imaging using fura-2 loading. RESULTS: Control and HHD keratinocytes displayed approximately the same Ca2+ levels in resting phase, while DD keratinocytes showed elevated Ca2+ levels. Application of ATP caused less pronounced elevation of intracellular calcium concentration ([Ca2+]i) in both HHD and DD keratinocytes than in control cells. HHD keratinocytes did not lower their [Ca2+]i as efficiently as control keratinocytes after treatment with thapsigargin. In addition, DD keratinocytes were practically incapable of lowering their [Ca2+]i after treatment with thapsigargin. CONCLUSIONS: The results demonstrate that the defects in SPCA1 and SERCA2 calcium ATPases result in distinct patterns of calcium metabolism. This is also supported by the different clinical features of the diseases.

[Darier disease type 1].

Darier disease (follicular dyskeratosis) is a rare genodermatosis determined by an autosomal dominant gene with variable penetration, characterized by a symmetrical eruption of hyperkeratotic papules with predilection to the seborrheic areas of the body. Unilateral, focal form is the one of the rare type of the Darier disease. Two clinical and genetical phenotypes of the segmental Darier disease have been recently reported: type 1--in which the skin outside of the localized manifestation is normal and type 2--showing a segmental affection in combination with diffuse skin involvement. The patient with type 1 segmental Darier disease is presented because of rare occurrence, diagnostic and therapeutic difficulties as well. The first keratotic papules on the left side of his trunk appeared at the age 14. The correct diagnosis based on clinical and histological picture has been established 38 years latter.

Genetic linkage for Darier disease (keratosis follicularis).

Darier disease is an autosomal dominant skin disorder characterized by abnormal keratinocyte adhesion. Recent data have provided evidence for linkage of the Darier disease locus to 12q23-24.1 in British families. We have carried out linkage analysis using the 12q markers D12S58, D12S84, D12S79, D12S86, PLA2, and D12S63 in 6 Canadian families. Pairwise linkage analysis generated positive lod scores at all 6 markers at various recombination fractions, and each family showed positive lod scores with more than one marker. The peak lod score in the multipoint analysis (Zmax) was 5.5 in the interval between markers D12S58 and D12S84. These positive lod scores in North American families of varied European ancestry confirm the location of the Darier disease gene, and suggest genetic homogeneity. The future identification and sequencing of the gene responsible for Darier disease should lead to improved understanding of the disease and of keratinocyte adhesion in general.

Localized Darier disease. Implications for genetic studies.

BACKGROUND: Darier disease is an uncommon genodermatosis characterized by the symmetrical eruption of keratotic reddish-brown papules occurring in the seborrheic areas of the body. A unilateral, or localized, variant has been identified. We report 4 new cases of localized Darier disease and review the English-language literature. The implications of these cases on future genetic studies are also discussed. OBSERVATIONS: Localized Darier disease occurred with equal frequency in males and females. The average age at onset was 27 years. The most frequent site of involvement was the trunk (40% [16/40]). This condition was aggravated by sunlight, heat, or sweating in 42% (19/40) of reported cases, and 38% (15/40) of the patients responded to treatment with topical tretinoin. CONCLUSIONS: Many of the clinical features of localized Darier disease suggest that it is a genetic mosaic of generalized Darier disease. Further studies of localized Darier disease may therefore prove to be instrumental in the search for the Darier disease gene.

Darier disease: sustained improvement following reduction mammaplasty.

Darier disease is an autosomal-dominant inherited genodermatosis. A woman is described who had Darier disease and hereditary spherocytosis whose inframammary Darier disease had dramatic and sustained improvement following reduction mammaplasty. The postoperative resolution of the dermatosis beneath the patient's breasts introduces the possibility that, when appropriately indicated, breast reduction surgery may have a potential role in the management of severe inframammary Darier disease.

Hypopharyngeal and laryngeal involvement with Darier disease.

The presence of mucosal Darier disease (keratosis follicularis) was evaluated clinically and histologically in four consecutive patients with moderate to extensive cutaneous manifestations of this disease. Fiberoptic endoscopy demonstrated hypopharyngeal or laryngeal involvement or both in each patient. A dearth of corps ronds and grains in these anatomical regions was observed histologically. The routine evaluation of mucosal involvement in Darier disease should result in a higher incidence of hypopharyngeal and laryngeal lesions than is currently known. Furthermore, the recognition of hypopharyngeal and laryngeal involvement with Darier disease must be emphasized because of the clinical similarity to leukoplakia and squamous cell carcinoma.

Darier disease: case report with oral manifestations.

Darier disease, also known as keratosis follicularis or dyskeratosis follicularis, is a rare autosomal dominant genodermatosis. It is clinically manifested by hyperkeratotic papules primarily affecting seborrheic areas on the head, neck and thorax, with less frequent involvement of the oral mucosa. When oral manifestations are present, they primarily affect the palatal and alveolar mucosa, are usually asymptomatic, and are discovered in routine dental examination. Histologically, the lesions present suprabasal clefts in the epithelium with acantholytic and dyskeratotic cells represented by corps ronds and corps grains. This paper reports a case of an adult male patient presenting clinical signs of Darier disease in the palatal mucosa and skin on the neck and upper limbs. Intraoral biopsy of the affected area, analysis of family history and evaluation by a multidisciplinary team led to the diagnosis of Darier disease. Dental professionals and pathologists should be aware of these lesions to allow correct diagnosis and proper management of this disease.

Segmental manifestation of Darier disease. What is the genetic background in type 1 and type 2 mosaic phenotypes?

Darier disease is an autosomal dominant disorder which may occasionally become manifest in a segmental form. Two clinical phenotypes with a different genetic background have been elaborated in recent years. More than 50 patients with isolated linear disease expression have been documented. In this phenotype the skin outside the segmental affection is absolutely normal. Such a phenotype is explained by a postzygotic mutation with somatic mosaicism which was labeled as type 1 manifestation of segmental forms in autosomal skin disorders. A patient with classical type 1 segmental Darier disease is presented. On the other hand, only 3 patients with Darier disease showing a segmental manifestation in combination with a diffuse distribution have so far been observed. These cases correspond to the recently described type 2 manifestation of segmental forms of autosomal dominant disorders. We describe a fourth patient with type 2 segmental Darier disease. The genetic explanation of such a phenotype is possible with the assumption that a germline mutation for the disease exists but, in addition, a postzygotic mutation is needed resulting in loss of heterozygosity. Hence, in a circumscribed region a homozygous or hemizygous state of the mutation is apparent which can explain the enhanced severity of the segmental manifestation.

Fatal herpes simplex virus infection in Darier disease under corticotherapy.

A 67-year-old man is presented with longstanding and severe Darier disease treated by topical antiseptics and potent corticosteroids, in combination with oral glucocorticoids and etretinate. After cardiac bypass surgery in 1997, the patient experienced herpes simplex virus (HSV type-1) infection of the skin that was treated by intravenous aciclovir. In 2003, he presented a widespread atypical exacerbation of his Darier disease, involving the face, trunk, buttocks, intertriginous areas and arms. Initial clinical signs and bacteriological findings suggested a bacterial involvement by multiresistant Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, and Proteus mirabilis. Despite antibiotherapy, the clinical presentation progressively worsened. A skin biopsy was performed and immunohistochemical examination identified a type-2 HSV infection. Although intravenous aciclovir was administered, the widespread cutaneous HSV infection was followed by systemic dissemination. A severe acute respiratory distress syndrome (ARDS) developed, leading to a fatal issue. At autopsy, a severe interstitial type-2 HSV pneumonitis with extensive necrotic areas was found, in association with gastro-intestinal involvement. This case represents, to the best of our knowledge, the first case of Darier disease presenting a fatal type-2 HSV infection. It underlines the importance of rapidly recognizing HSV infection in Darier disease and stresses the risk of lethal outcome. The different risk factors for HSV infection in this patient are reviewed.

Type 2 segmental Darier disease.

A 45-year-old man had bilateral disseminated involvement of Darier disease, and two of his sisters likewise had lesions suggesting this trait. Remarkably the propositus showed, in addition, a unilateral, systematized, segmental pattern of excessively pronounced Darier lesions. This unusual case can be taken as an example of type 2 segmental Darier disease. In contrast to the type 1 segmental manifestation that develops from a new mutation occurring in an otherwise healthy embryo, the type 2 segmental involvement would originate in a heterozygous embryo from postzygotic loss of the corresponding normal allele, resulting in a cell clone that is either homozygous or hemizygous for the mutation. This concept would explain why the segmental lesions were excessively pronounced and superimposed on the ordinary trait. Future studies may show whether the concept of type 2 segmental Darier disease can be confirmed at the molecular level.

Mutational analysis of the ATP2A2 gene in two Darier disease families with intrafamilial variability.

BACKGROUND: Darier disease (DD), an autosomal dominant genodermatosis characterized by warty papules and plaques over seborrhoeic areas, is caused by mutations in the ATP2A2 gene, which encodes the sarco/endoplasmic reticulum Ca(2+) ATPase type 2 isoform (SERCA2). While markedly different clinical severity within DD-affected family members is known, the pathomechanism has not been elucidated. OBJECTIVES: Based on the hypothesis that multiple ATP2A2 mutations might contribute to the pathomechanism, we have analysed two DD families in which the clinical severity differs markedly within a single pedigree, and, as controls, eight DD families without differing clinical severity. METHODS: All the exons and intron-exon borders of ATP2A2 were directly sequenced from the genomic DNA extracted from all the subjects. RESULTS: We identified the heterozygous mutations, G233R in pedigree 1 and C318R in pedigree 2, respectively, whereas no other ATP2A2 mutations in any of severely affected individuals were found. In eight DD pedigrees as control, we have found M1V, N39D, L180R, A838P and 2170 insertion G in each of five pedigrees, but no mutation was found in three DD pedigrees. CONCLUSIONS: Our results together with previous data indicate that the distribution of mutations is scattered over the entire ATP2A2 without any, as yet, discernible 'hotspots'. The mutations in pedigrees 1 and 2 with intrafamiliar clinical differences occurred around the Ca(2+)-binding sites on SERCA2, which might be associated with differences in clinical severity. These variations in ATP2A2 mutations alone cannot account for the clinical heterogeneity within DD pedigrees.

[Intertriginous acantholytic dyskeratosis: abortive form of Darier disease or a specific entity?].

A 69-year-old woman presented with widespread symmetrical papular lesions in submammary and inguinal areas. History revealed that the disease had only been present for a few years. A skin biopsy showed focal suprabasal acantholysis, dyskeratosis up to the horny layer and in part parakeratotic hyperkeratosis. The patient had no further evidence for Darier disease, Hailey-Hailey disease or pemphigus vegetans. In particular, characteristic lesions of Darier disease of hands and nails were absent. We found several reports in the literature describing similar skin lesions in intertriginous and genital areas with histological evidence of acantholytic dyskeratosis under various terms. This report discusses the difference between these cases and the differential diagnoses, in particular Darier disease. We propose to designate cases of intertriginous papulosis with histological proof of acantholytic dyskeratosis but without further evidence of Darier disease as intertriginous acantholytic dyskeratosis.

Case report of Darier disease localized to the vulva in a 5-year-old girl.

A 5-year-old girl with Darier disease had numerous verrucous papules coalescing into plaques on both labia majora of approximately one year's duration. She was diagnosed as having genital warts, raising the suspicion of sexual abuse. Subsequently, a biopsy specimen from one of the vulvar lesions revealed histologic characteristics consistent with a diagnosis of Darier disease. The case is unusual for the age of onset and the site of initial involvement, and stresses the importance of including acantholytic disorders such as Darier disease in the differential diagnosis of a child with clinically verrucous lesions.
