Trichost.asis Spinulosa consists of several fasciles of reta ned vellus hairs in the hyperkeratotic sebaceous follicles, resulting in a dark slightly raied horny follicular spines, resembling comedones on the trunk and face. The condition is relatively common, particulary among the age, but is usually overlooked on routine skin examination as the patient is rarely aware of it.. We report 6 cases of trichostasis spinulosa, which showed numerous asymptomatic tiny black comedo-like dots on their backs. We obtained the follicular material by tweezer, which consised of several vellus hairs surrounded by a keratinous plug. Histologic examination was done in 3 patients, one of whom showed a rarely reproted double follicle and double papilla. With scanning electron microscopy, we observed multiple vellu hairs embedded in a keratotic plug, emerging from a hair follicle opening.

The infection with tapeworm of the Mesocestodes sp. has been rarely reported and only 8 cases of human infection were found in the world up to date. This is to report the first case of human infection with this tapeworm belonged to Cyclophyllidea in Korea. In January 1967, a 45 years old man visited to the out clinic of St. Mary's Hospital with the complaints of intermittent indigestion and abdominal distension nearly for 1 year. Laboratory findings appeared almost normal except increased eosinophils up to 14 per cent. The characteristic ova of Mesocestoides sp. were found by the serial stool examinations, which contained hexacanth larva inside the egg shell without operculum as in Cyclophyllidea. It was failed to reveal the scolex by the first evacuation, but one among 3 worms evacuated by the treatment with atabrine and enough purgations 2 months later, has been found the characteristic scolex. They were 85 cm to 136 cm long and the scolex had 4 distinct suckers but no rostellum, the matured proglottid had numerous testes bilaterally and ovary with yolk glands in central parts, and in the gravid proglottid spiral uterus was opened to uterine pore and characterized by the spherically distended uterine capsules. The patient had the history of ingestion of 15 snakes as raw about 1 year ago as usually seen in Japanese cases.

Midline malignant reticulosis is a relentlessly progressive, localized, destructive inflammatory process of upper respiratory tract including the nose, nasopharynx, palate, paranasal sinuses, and midface. Histologically, it is characterized by a dense aceumulation of pleomorphic mononuclear cells with an admixture of inflammatory cells. We report a case of midline malignant reticulosis developed in a 64-year-old man, who showed a serosanguineous nasal discharge, perforation of nasal septum, persistent ulceration of hard palate, and disseminated lesions on the abdominal skin, which was confirmed by histopathalogical examination. In addition we studied infiltrated cells with atypical nuclei by immunohistochemical staining with a pannel of monoclonal antibodies. The results revealed that the atypical cells expressed the T-cell marker, but not the macrophage and B-cell marker.

The present study was carried out to investigate the HHsAg in the normal skin, dis- eased skin and skin specimens of window period of HBsAg positive patients in their serum with normal liver function. This study was done by immunoperoxidase techniques using the monoclonal antibody to hepatitis E3 surface antigen and by electron microscopy. Immunoperoxidase staining was dane on twenty specimeris of normal skin Group .D twenty specimens of diseased skin (15 cases of dermographism, 2 cases of purpura, 1 case of follicuht,is and 1 cases of morbilliform eruption) (Ciroup II ) and three specimens of normal skin af window period (Group III ) of HBsAp positive patients in their serum. Twelve cases of Group I, eleven cases of Group IL (1(J cases of dremographism and 1 rase of purpura) and two cases of Group II were stained positively for HBsAg. Positive sites were keratinocyte of epidermis, sweat gland, blood vessel and hair follicle. Electron microscopy failed to reveal viral particle, The above resuts suggest the possibility of transmission of viral hepatitis B thraugh the skin and skin appendages.

Porokeratosis may be due to an abnormal clone of cells, predisposing affected individusls to development of malignant neoplssm over involved area. A 58-year old female is prsented with basal cell epithelioma associated with PPPD, exhibiting the classical histopathologic criteria of the disease. Total excision for basal cell epithelioma and oral administration of etretinate for the treatment of porokeratosis plantaris, palmaris et disseminata and for the prevention of cancer developrnent resulted in good response.
