A 52-year-old man with multiple myeloma developed cutaneous nodules while being treated with melphalan and prednisolone. A biopsy specimen showed dermal infiltration by well differentiated plasma cells similar to those found on bone marrow biopsy. The use of peroxidase anti-peroxidase to demonstrate the monoclonality or polyclonality of the cytomplasmic immunoglohulins in the tumor cells revealed a positivity for IgG and 1 chain (ie, monotypic staining). Ultrastructurally, each plasmacytoma cell contained varyting amounts of rough endoplasmic reticulum and Golgi-apparatus. The cutnneous nodules completely disappeared after radiotherapy

Telangiectasia is characterized by permanently dilated small vessels usually arising from the suprapapillary plexus of venule capillaries, or arterioles. It may be etvlogically divided into the primary and secondary types. Rosacea, varicose vein, prolonged sun xvsure, radiation, and physical trauma may be the causes of secondary telangiectasia. We report herein a case of secondary telangiectasia associated which operation for a femur fracture.

BACKGROUND: Primary targit injured from the immunologic mechanism of alopecia areata is not definitely confirmed although alopecia areata is regarded as a disease occuring from certain im munologic process. Recently, par ticular interest has been focused on the follicular keratinocytes which show morphologic and anigenic alterations in active lesions. Another important point is the subclinical state hypothesi. It is based upon the observation that the patterns of T lymphocytes infiltration and ultrastructural changes of dermal papilla cells are nearly identical in active lesions and in non-lesional areas of alopecia areata. OBJECTIVE: The purpose of this study is to determine and to compare the aberrant expression of HLA-DR, CD1 and ICAM-1 on the follicular keratinocytes from the active alopecia areata lesion, stationary lesion and non-lesional scalp. METHODS: We performed a n immunohistochemical study, using the streptavidin system to compare the patterns of HLA-DR, CD1 and ICAM-1 immunoreactivity in the follicular keratinocytes in five active alopecia lesions two stationary lesions and non-lesional scalp specimens among four active and two stationary patients, and two normal control scalp specimens. RESULTS: In the active aloecia lesions, the HLA-DR and ICAM-1 immunoreactivity was observed in some patients while CD1 immunoreactivity was observed in all the patients. In the sta tionary alopecia lesions, none of the HLA-DR or CD1 or ICAM-1 immunoreactivity was observed as was the case in the norrial control scalp specimens. In the non-lesional normal scalp specimens, the HLA-DR, CD1 and ICAM-1 immunoreactivity showed nearly the same patterns as those in the acute alopecia leions. CONCLUSION: The aberrant antigenic alterations, especially CD1 expression of follicular keratinocytes are likely to be asociated with the active progress of alopecia areata lesions. These antigenic alterations were also observed in non-lesional scalp as well as alopecia areata lesions in the very similar patterns.

We report a case of a morphologic variant of dermatofibroma. A coin sized, brownish, shinny, somewhat fibrotic pedunculated tumor in a 39-year-old male was diagnosed as a sclerosing hemangioma, a type of dermatofibroma histopathologically. Its dome shape morphology was unusual in comparison with the typical morphology of dermatofibroma that we know.

We present cases of localized idiopathic lipoatrophy occurring in two women. A 19-year-old girl had symmetrically distributed annular telangiectatic atrophy on both buttocks and a 44-year-old female had annular telangiectatic atrophy on the right buttock. The histopathologic findings of these lesions revealed numerous capillaries, various sized lobules with small round or spindle shaped cells on a background of hyaline material in subcutaneous layer. Two cases of lipoatrophy which shows the involutional phase are reported.

A 4-year-old boy has had a solitary sclerotic depressed plaque on the right anterior chest since birth. The histopathologic findings are consistent with morphea profunda: thickening, hyalinization, and homogenization of collagen bundles in the dermis and subcutaneous tissues, admixture with a prominent lymphocytic and plasma cell infiltrate, and sweat glands en-trapped between the thickened collagen bundles. We report a case of congenital solitary morphea profunda.

We present a case of systemic lupus erythematosus(SLE) asseci ted with vitiligo in a 57 year-old male patient. Physical examination revealed two distinct skin lesions those of itiligo showed as centrally located depigmented patches surrounded by erythernatous patch on the right cheek, scalp and left dorsurn of hand and those of SLE showed as erythematous papules and patchs with partial adherent scales on the face, scalp, neck, both extensor surface of arm, and left dorsun of hand. Their coexistence lends credence to the contention that altered autoimrnunity may play a role in the pathogenesis of each of these diseases. In Western countries and Japen, patients with lupus erythema osis have been observed to develop vitiligo or depigmented spots on the skin, while in Korea, its has not been previously observed.

We report a case of type III hyperlipoproteinemia which is called a broad-beta disease. A 53 year old female patient visited our clinic for the evaluation of multiple yellowish papules on extremities and eyelids. The patient showed various types of xanthoma includiiig eruptive, tuberous, tendinous xanthomas and xanthelasma palpebrarum, xanthoma striatum palmare. The blood chemistry revealed a marked elevstion of cholesterol and triglycerides and agarose gel electrophoresis showed a single peak at prebeta and beta portion without separation. On histopathologic studies, typical foam cells were showen.

A 55-year-old Korean female patient who presented with longitudinal black pigmentation affecting the right thumbnail is described. Direct microscopic examination of nail tissue in 15% potassium hydroxide and cultures on Sabourauds glucose agar revealed Candida species. Cardida species as a cause of longitudinal melanonychia has, to our knowledge, been described only once in the literature. Our case may be the second one.
