Traumatic eosinophilic ulcer of the oral mucosa: a misdiagnosed entity.

We report a case of and review the literature on eosinophilic ulcer of the tongue. This is a benign entity frequently unrecognized in clinical practice, with only occasional mention in the literature, the clinical signs of which are easily confused with those of squamous cell carcinoma. Although the histopathologic appearance of this entity is distinctive, its clinical course and rapid healing without therapy themselves constitute strong diagnostic clues, making diagnostic or therapeutic bloody methods generally unnecessary.

Hairy leucoplakia and HIV-2--a case report and review of the literature.

Type 2 human immunodeficiency virus (HIV-2), originally confined to West Africa, has lately appeared with increasing frequency in Europe. Oral lesions affect a large proportion of patients with AIDS. Hairy leucoplakia (HL), a clinical expression of Epstein-Barr virus (EBV), is a lesion of the oral mucosa (usually the lateral margin of the tongue) that is observed in patients who are immunocompromised due to HIV or, more rarely, due to immunosuppressive medication or other causes. We review the definition, clinical signs, histopathology, diagnosis, prognosis and treatment of HL, and report the (to our knowledge) first detailed description of an HIV-2-seropositive patient with HL, which affected the lateral and dorsal tongue and was the first clinical sign of HIV infection (this patient was at that time only the second native Spaniard in whom unique HIV-2 infection had been detected). EBV detection and subtyping by in situ hybridization and polymerase chain reaction were performed in paraffin-embedded tissue from the HL lesion of the dorsal tongue; EBV-1 and EBV-2 were detected by the latter technique.

Linear and whorled nevoid hypermelanosis.

A case of hyperpigmentation distributed in streaks and whorls was recently delineated and separated from a confusing number of pigmentary disorders. A 13-year-old boy had hyperpigmented, reticulate spots on his trunk and neck in a linear and whorled distribution following the lines of Blaschko. Onset was at age 1 year. Histologically, the spots showed increased melanin in the basal layer of the epidermis, but no increase in melanocytes, incontinence of pigment, or melanophages were seen in the dermis. The karyotype was 46,XY and there was no evidence of chromosomal mosaicism or chimerism. This entity represents a disorder separated recently from other pigmentary alterations that follow Blaschko lines, such as Bloch-Sulzberger incontinentia pigmenti, hypomelanosis of Ito, early systematized epidermal nevus, and chimerism.

Cystic giant solitary trichoepithelioma.

A case of a giant solitary trichoepithelioma is reported. The tumor was located on the thigh, extending from the deep dermis to the subcutaneous tissue with no epidermal contact, and showed a large central cystic cavity that measured 9 cm x 4 cm. We review the cases published under this and other names.

Incidence of leukocytoclastic vasculitis in chronic idiopathic urticaria. Study of 100 cases.

One hundred cases of chronic idiopathic urticaria (CIU) were studied to determine the incidence of leukocytoclastic vasculitis (LV) and the clinical and laboratory data that might indicate its presence. LV was found in 12 patients, none of whom had either clinical or laboratory data to suggest its presence. These results suggest that a small percentage of patients with CIU. 12% in this series, have LV without either clinical or laboratory signs of its existence.

Woolly-hair nevus: report of a case associated with a verrucous epidermal nevus in the same area.

We cared for a patient with woolly-hair nevus (WHN) with hair of reduced diameter seen as oval shaped on transverse section. Scanning electron microscopy revealed a longitudinal canal along the length of the hair shaft. Although the association of WHN and epidermal nevus has been described previously, this report of their localization in the same site is, to our knowledge, the first in the literature.

[Segmental neurofibromatosis].

Four cases of segmental neurofibromatosis (SNF) are reported. It is a rare entity considered to be a localized variant of neurofibromatosis (NF)-Riccardi's type V. Two cases are male and two female. The lesions are located to the head in a patient and the other three cases in the trunk. No family history nor transmission to progeny were manifested. The rest of the organs are undamaged.

[Spitz's nevus: clinicopathologic study of 25 cases].

We reviewed the clinical and histopathologic findings in 25 Spitz's nevus who were evaluated at our institution from 1980-1988. 18 cases in patients aged 20 years or less and 7 cases in adults. 14 are female and 11 are male. Represent the 3.88% of melanocytic nevi etude in the same time. Eosinophilic globules were find in 64% of the cases. We include a pigmented spindle cell nevi (non-Spitz), we thinks is a variant of Spitz's nevus.

Perforating pilomatricoma.

A case of perforating pilomatricoma is described. A few published cases have shared the following features: rapid development, reddish exophytic clinical appearance with surface alterations suggestive of perforation, relatively shallow location making contact with the epidermis, and the occurrence of transepithelial elimination phenomena.

Tubular apocrine adenoma.

We report a case of tubular apocrine adenoma located on the scalp, with characteristics of syringocystadenoma papilliferum in the superior part of the lesion. An interesting feature of the growth is its connective tissue involvement.

Autosomal dominant lamellar ichthyosis.

Five members of two generations of one family were affected with lamellar ichthyosis, suggesting autosomal dominant transmission. The clinical and histopathological characteristics of the cases described here are similar to those reported by Traupe et al. (1984) as autosomal dominant lamellar ichthyosis and thus confirm the existence of this new form of ichthyosis.

[Perforating necrobiosis lipoidica].

This is the case history of a woman with a 6 year history of insulin-dependent diabetes mellitus and a 5 year history of tuberous lesions on the dorsal aspect of the metacarpophalangeal joints. Histological examination revealed multiple necrobiotic foci throughout the dermis and subcutaneous tissue, with varying degrees of degeneration, alternating with fibrotic areas. This picture is compatible with lipoid necrobiosis. The existence of various foci of epithelial perforation, manifested clinically by a point hyperkeratosis similar in appearance to blackheads, suggests transfollicular elimination. This would explain the total absence of a pilosebaceous follicles in the lesion.

Rubinstein--Taybi syndrome and ulerythema ophryogenes in a 9-year-old boy.

Rubinstein-Taybi syndrome is characterized by the presence of a peculiar facies, mental retardation, and broad thumbs and great toes. Several associated cutaneous abnormalities have been reported with this syndrome. Ulerythema ophryogenes is a form of follicular keratosis associated occasionally with other ectodermal defects and congenital anomalies. We describe a 9-year-old child with Rubinstein-Taybi syndrome and ulerythema ophryogenes. This association has not been described previously to our knowledge.

Chronic infection due to Fusarium oxysporum mimicking lupus vulgaris: case report and review of cutaneous involvement in fusariosis.

A 67-year-old female presented with a 20-year-old lesion involving the right ear and preauricular area mimicking tuberculous lupus. Fusarium oxysporum infection was confirmed by biopsy studies and cultures. The biopsy specimen showed an unusually extensive dermal invasion with fungal hyphae. This is an uncommon clinical presentation for Fusarium infection in a healthy patient. When referred to us, the patient had received antifungal therapy with itraconazole without any benefit. Improvement was obtained with fluconazole therapy. The spectrum of cutaneous involvement related to Fusarium spp. includes toxic reactions, colonization, superficial indolent infection, deep cutaneous or subcutaneous infections and disseminated infection.
