Keratosis lichenoides chronica: a variant of lichen planus.

In order to establish a possible relationship between keratosis lichenoides chronica (KLC) and lichen planus (LP), we performed a comparative study which included routine histologic examination, electron microscopy, and direct immunohistochemical studies from one case of KLC and several patients with LP. Our findings demonstrate that KLC and LP share many similarities; their differences are mostly quantitative. In KLC, the findings are more prominent; we therefore conclude that KLC is at one end of the spectrum of LP.

Leukocytoclastic vasculitis--correlation between different histologic stages and direct immunofluorescence results.

BACKGROUND: Leukocytoclastic vasculitis is a well-known clinico-pathologic entity. A good correlation between clinical and direct immunofluorescence (DIF) findings has been shown only in the early stages of vasculitis. Our purpose was to determine the correlation between different stages of vasculitis, etiology of vasculitis, and DIF findings. METHODS: Histologic and DIF studies were performed and evaluated from 40 patients with leukocytoclastic vasculitis. RESULTS: Thirty-seven out of 40 patients (92%) showed positive DIF findings in the blood vessel walls. Eight patients were in the early stage of vasculitis and exhibited deposits mainly of fibrinogen, C3, and IgM. Seventeen patients were at the fully developed vasculitis stage and showed albumin, fibrinogen, and IgG deposits. Fifteen patients were in the late stage of vasculitis and showed deposits of mainly fibrinogen and C3 in the blood vessel walls. CONCLUSIONS: The present study demonstrates that DIF examination is a very sensitive test in the diagnosis of vasculitis, and can be used in all stages of vasculitis and not only in the early stages as has been shown in previous studies.

A case of pemphigus vulgaris with esophageal involvement.

Esophageal involvement in pemphigus vulgaris is rare, found more in women than in men, and can be the only manifestation of pemphigus. Esophageal involvement had been reported only among patients with pemphigus vulgaris and not in patients with other forms of pemphigus. We describe a case of pemphigus vulgaris in which the esophagus was severely involved with only few oral lesions and no involvement of the skin or oropharynx.

Masturbation in prepubescent children: a case report and review of the literature.

A 10-year-old girl observed to have episodes of flushing, pallor and weakness, was referred for investigation of possible carcinoid syndrome. The cause of these episodes was masturbation. Masturbation occurs at all ages and in most cases is considered normal behaviour. Lack of recognition of this phenomenon in children may lead to unnecessary investigations and treatment.

Skin reactions due to eye drops: report of two cases.

Although eye drops are widely used, adverse skin manifestations are not frequently observed and described. We report two patients who experienced adverse cutaneous manifestations during treatment with eye drops containing timolol maleate and chloramphenicol.
