Hidradenitis suppurativa in Crohn's disease. A further support to this association.

A patient with Crohn's disease (CD) subsequently developed the clinical and histological features of hidradenitis suppurative (HS). So far, only five cases with such an association have been reported. Azathioprine (150 mg/d) and methylprednisolone (16 mg/d) for CD combined with isotretinoin (0.7 mg/kg) and periodic administration of antibiotics for HS were used. The treatment was satisfactory, and the patient is now in clinical remission for both diseases.

Anonychia of all toes with absence of phalangeal bones.

A ten year old girl suffered from anonychia of all toes, present from birth. The absence of nails was accompanied by absence of one or two phalangeal bones in toes other than the big toes. Other abnormalities consisted of short toes, incomplete syndactyly of the 2nd and 3rd toes of each foot and transfer of the dermatoglyphics from the plantar to the dorsal surface of the digits. The combined defect of the nails and the phalangeal bones can be explained by the close relationship of the two structures during the morphogenesis of the digits.

Orf. Clinical and epidemiological study.

Twenty eight human cases of orf were studied from clinical and epidemiological points of view. Most of the patients were shepherds who were inoculated from infected animals during all seasons of the year. Typical lesions of different stages of orf were located on the hands, and were accompanied by local symptoms such as pain, pruritus, lymphangitis and adenitis, or less frequently by systemic symptoms such as fever or malaise. Two cases developed erythema multiforme, one developed erysipelas and another a papulovesicular eruption. Tzanck test may contribute to the diagnosis. The course of the disease can not be influenced by antibiotics, and only measures of local hygiene are recommended, except in complicated cases.

Congenital sensory neuropathy with anhidrosis (hereditary sensory neuropathy type IV).

Hereditary sensory neuropathies comprise a group of rare childhood diseases which are classified into four types. We present a Greek boy 11 years old with hereditary sensory neuropathy type IV (congenital sensory neuropathy with anhidrosis) whom we have followed up and studied during the last seven years. Our patient presented for the first time with recurrent hyperthermic episodes without sweating, and lack of pain sensation from the first months of life. Insensitivity to pain and thermal stimuli had resulted in burns on the extremities and self-mutilation of the tongue, lips and fingertips. When he was five and seven years old respectively he had two painless fractures of the ankles which led to insoluble orthopedic problems. He also suffered from mental retardation, which was obvious from his first years of life. Sweat gland investigations showed significant hypohidrosis or anhidrosis although the sweat glands were normal microscopically. Hereditary sensory neuropathy type IV, although rare, is important for dermatologists because it must be differentiated from other anhidrotic syndromes, and in view of the poor prognosis of the condition.

Fixed drug eruption in a mother and her son.

Two cases of fixed drug eruption, occurring in a mother and son, are presented. The eruption in the mother occurred after she ingested dimenhydrinate or acetylsalicylic acid and in the son after ingestion of either of the above drugs or with "junk" food (cheese crisps). Apart from the drugs, anxiety was found to be an essential factor in the manifestation of the mother's disease. A genetic predisposition would seem to link these cases.

Study of the primary crest 'pavement' structure in healthy skin.

The primary crest surface of the healthy skin may have a smooth appearance or form a 'pavement'-like picture because of the presence of circular or polygonal subunits. In this study, the primary crest pavement structure was examined in different sites of healthy skin. The pavement structure was found in 70-100% of the adjacent areas of the palms and soles, and also on the skin of the elbows and knees. This pavement formation is absent on the skin surface of other areas or may be found in a small percentage of 5-20%. It is possible that the pavement structure could represent modified dermatoglyphics in the hairy skin.

Subacute cutaneous lupus erythematosus in Greece. A clinical, serological and genetic study.

We present herein clinical, serological and genetic findings on 27 Greek, subacute cutaneous lupus erythematosus (SCLE) patients. Twenty-three (85 p. 100) presented with a psoriasifom rash in a photosensitive distribution. Two patients (7.5 p. 100) had an annular rash in a polycyclic pattern. Two other patients exhibited both types of lesions. The majority of our patients also had other skin manifestations, including butterfly rash, discoid lesions and maculopapular rash. Systemic manifestations were: arthralgias or arthritis in 50 p. 100, low grade fever in 35 p. 100, central nervous system involvement in 15 p. 100, Sjögren's syndrome in 18 p. 100 and serositis in 8 p. 100. Anti-nuclear antibodies were found in 93 p. 100; antibodies to Ro (SSA) and/or La (SSB) in 70 p. 100. Twenty-one (78 p. 100) satisfied the ARA criteria for systemic lupus erythematosus (SLE). No HLA-DR3 antigen association was found in the 16 patients tested. These findings are somewhat different from those reported previously: a) the frequency of the psoriasiform rash rather than the annular one is the highest in Greek SCLE patients; b) most patients also have other skin manifestations mimicking the full spectrum of SLE with prominent cutaneous lesions; and c) no HLA-DR3 antigen association was found in Greek patients. Environmental, ethnic or genetic factors may be responsible for these differences.

A five year retrospective study on pemphigus and pemphigoid.

In a five year period 73 cases of pemphigus vulgaris (PV) and 94 of bullous pemphigoid (BP) were studied to investigate important parameters for these diseases. From the results it was found that the incidence of PV was higher in women whereas that of BP was almost equal in both sexes. The incidence of PV was highest in the sixth decade but was highest in the eighth decade for BP. Indirect immunofluorescence (IIF) was more sensitive in PV whereas direct immunofluorescence (DIF) was more sensitive in BP. The present study provides a basis for comparison with results of previous or future studies in Greek and other populations.

Vitiligo as a reaction to topical treatment with diphencyprone.

During the topical treatment of 45 patients, who had extensive forms of alopecia areata, with the allergen diphencyprone, 3 of them (6.7%) developed vitiligo. Two were females and 1 male aged 53, 19 and 28 years respectively. None of these patients had a personal or family history of vitiligo. Vitiligo appeared 3-5 months after the onset of treatment and was localized only to the areas of topical application in the younger woman and the man. In the older woman, vitiligo extended to several areas apart from those where the medicament was applied. After the end of diphencyprone treatment, vitiligo had a spontaneous significant improvement only in the man. Mitochondrial autoantibodies were found in the older woman only. To our knowledge, vitiligo due to diphencyprone has not been previously reported.

Nuchal nevus flammeus as a skin marker of prognosis in alopecia areata.

In this work, the incidence of nuchal nevus flammeus was studied in 205 patients suffering from various forms of alopecia areata, as well as in a group of 555 volunteers without alopecia areata examined in our outpatient clinic. The incidence of nuchal nevus flammeus in the totalis-universalis form of alopecia areata was 58.2% (examined patients, n = 79), in ophiasis-extensive forms 22.8% (examined patients, n = 70) and in simple forms of alopecia areata 3.6% (examined patients, n = 56). In the group of 555 volunteers without alopecia areata the incidence of nuchal nevus flammeus was 4.5%. Our results show that nuchal nevus flammeus could be a valuable skin marker indicating a more severe course of alopecia areata.

Delayed hypersensitivity and differences of histologic pattern in allergic cutaneous vasculitis.

Fourteen patients with allergic cutaneous vasculitis of either the polymorphonuclear (PMN)- or the mononuclear (MN)-predominant type were studied as regards the following parameters: the disease duration, histology, monoclonal antibody typing of the mononuclear cell infiltrate from recent lesions, and the delayed hypersensitivity (DH) response, assessed both by recall antigens (tuberculin type) and the dinitrochlorobenzene skin test. From the results, it was shown that in PMN-predominant vasculitis, DH reactions were well elicited, whereas in MN-predominant vasculitis, DH skin reactions were somehow impaired. In MN-predominant cases, many OKT3+, OKT4+, OKT8+, and OKM1+ cells were usually seen to surround the skin vessels, whereas in PMN-predominant cases, rare OKT8+, OKT4+, or OKM1+ cells were seen in the dermis. The epidermal dendritic cell system, as revealed by the Na(1)34 monoclonal antibody, was unaffected in both types of allergic cutaneous vasculitis.
