We report two cases of dyschromatosis symmetrica hereditaria. One is a 12-year- old female and her family had five individuals with similar pigmentary disorder through three generation. The other is a 22-yesr-old female who had no family history of similar disease. Fontana-Masson stain revealed increased and decreased melanin granules in the basal cell layers in the pigmented and depigmented lesions respectively.

Malignant fibrous histiocytoma is the most common soft tissue sarcoma in adult life and shows a mixed proliferation of both fibroblsstic & histiocytic cells. We report a case of myxoid malignant fibrous histiocytoma involving right lower leg in a 68-year-old male patient, who presented with a childs palm-sized nodular mass of 3 years duration. Histoapthologically, the tumor had varying proportion of myxoid & cellular components. The myxoid areas showed spindle and pleomorphic cells arranged in a vague storiform pattern, abrupt transition between a solidly cellular area and a myxoid area, and lipoblast-like cells. The cellular areas showed spindle cells arranged in a storiform pattern characteritic of the typical pleomorphic malignant fibrous histiocytorna. (Kor J Dermatol 28(1): 94 98, 1990)

This mycological and cultural investigation was made in 86 cases of onychomycosis diagnosed on positive KOH wet mount at Chosun University Hospital from October, 1989 to February, 1990. The results were as follows : l. The ratio of male to female was 1.2:1. According to Zaiass classificat.ion, distal subungual onychomycosis (DSO) was the most predominant type(79 cases) and others, in decreasing frequency, were superficial white onychomycosis (SWO) (Fcases), total dyst,rophic onychomycosis (TDO) (1 cases, and proximal subungual onychomycosis (PSO) was not. found. 2. In DSO, isolat,ed fungi were T. mentagrophyte(31 cases), i'. rubrum(23 c<ses), saprophyt.es(7 cases) and C albicans (5 cases). In SWO, 2 species were isolated, which were T. mentagraphytes (5 cases) and saprophyte (1 case). C. albicans was cultured in one case of TDO. 3. Eight cases of iisolat,ed sapr ophytes were Aspergillus ( 5 cases), Scopulariopsis (1 case), Hormodendrum(1 case), and Cepalosporium(1 case). Saprophytes were tound only in toe nails. 4. Uo saprophytes were isolated from coexisting skin lesi.ons. Among 10 cases of coexisting tinea manus and/or tinea corporis, T. rubrum were cultured in 8 cases. 5. The positive rate of culture by two different sampling methods and media was as follows : On Sabouraud glucose agar media, it was 47.7% (41 cases) by clipping methodand 40.7% (35 Cases) by file-method. On dermatophyte test medium, it was 43.0 (3'7 eases) by cliipping method and 45.3% (39 cases) by file-method. It seem that the selection of sampling site is important in increasing the positive rate in culture of onychomyc.osis. (Kor J Dermatol 29(1): 50 55, 1991)
