Trichostasis spinulosa was first described by Nobl in 1913 to denote a condition characterized by protruding groups of hairs embedded in horny mass on the nose, forehead, shoulder, and back. We report a case a 27-year old male patient with trichostasis spinulosa who showed multiple black colored papules on his back and upper arms. Histologic examination showed hair follicles surrounded by hyperkeratotic band which had multip]e hairs. By scanning electron micnoscopy, also, we could find several hairs of different size in the hyperkeratotic hair shealh.

Verrucous czrcinoma is a well accepted clinicopathologic entity that is a lowgrade variant of squamous cell carcinoma. This tumor develops typically in moist areas which are frequent site of chronic inflammation. We herein report a case of verrucous carcinoma developed in a burn scar on. the posterolateral aspect of left popliteal fossa.

Various immunologic investigations of 159 patients with Behqets syndrome undertaken included; the DNCB sensitization test, total T-cells and T-cell subsets and the lymphocyte transformation test using PHA. The percentage of positive esponsiveness to DNCB decreased in the order of possible (65%), suspected (60%), incomplete (37%) and complete type (37%), The number of patients with impaired LTT was larger in the group of patients with DNCB( + ) responsiveness (seventeen of 32) than in DNCB(+) group (six of 25), There was significant impairment of cell mediated immunity in Behcets syndrome compared to normal subjects, when analyzed by the impaired LTT and decreased proportions of helper T-cells.

We describe a case of cutaneous chylous reflux, which is thought to be a kind of primary lymphedema, in a 19-year-old male who had suffered from multiple vesiculobullae and intermittent swelling on scrotum for about 6 years. Histopathologic findings showed multiple dilated lymphatic vascular channels in papillary dermis.

A case of 39-year-old male with keratosis palmoplantaria nummularis was reported. The skin lesions were characterized by the presence of painful focal keratoses on the plantar pressure points. Biopsy of a keratotic plantar lesion revealed excessive hyperkerstosis, hypergranulosis, focal hypogranulosis, and acanthosis in the epidermis. We could observe aymptomatic relief of this patient who was treated with mixture of corticosteroid, 25% urea and 2.5% salicylic acid.

Various immunologic studies were performed for the investigation of humoral immunity in 30 patients with Behcet's syndrome who had been registered in Behcet Special Clinic of Severance Hospital: direct immunofluorescent staining, quantitation of serurn Ig, complement by immunoelectrophoresis and B-cell by EAC-rosette method. The results can be summerized as follows: 1. Direct immunofluorescent staining occurs in biopsies from patients with Behcets syndrome: 11 of the 30 patients(36. 7%). Among them, vascular fluorescene with C3 was noted in 10 of 11 patients (90. 9%), in addition of IgG, IgA, IgM, and fibrinogen on dermoepidermal junction or vessel. 2. The results of direct immunofluorescence staining showed different tendency according to biopsy sites and clinical types: 5 of 10(50%,) in the specimens from oral mucosa, 5 of 13(38.5%) from leg, 1 of 3(33.3%,) from genitalia, and 0 of 7(0%) from other sites: higher in complete and incomplete types than in suspected and possible types. 3. Immunofluorescent staining rates were statistically not significant according to sex, age and Lehner's classification. 4. Serum IgG, IgA, IgM, C3, C4 and B-cell were statistically not significant between DIF positive and negative groups. Therefore it is considered that vascular deposits of immune complexes and activation of complements by immune omplexes may be a role of pathogenetic mechanisms of Behcet's syndrorne.
