An 8-year-old girl had a rice sized erythematous nodule secreting mucoid fluid situated above the right sternoclavicular joint area since birth. Histopathological findings of the lesion revealed predominant mucous acini, serous acini, demilunes of mixed acini and excretory ducts in the deep dermis compatible with salivary gland. Electron microscopic findings revealed a lumen and serous cells containing serous granules and rough endoplasmic reticulurn. Recurrence has not been noted following total excision of the nodule.

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.

The technique of plssma exchange has been applied to a number of immune disorders in which c4eulating antibodies are present. We observed a patient with bullous pemphigoid and serious side effects of longterm use of steroid therspy. We applied ten times of plasmapheresis to him over six months period. After the plasmapheresis, clinical symptoms have greatly improved and steroid maintenance doses have been decreased. We have not observed any side effect of plasmapheresis such as thrambotopenia or hypogarnrnaglobulinemia during the whole therapeutic period.

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.

"Cutaneous horn", the clinical term first defined by Moncorps in 1931, has been used to describe those markedly hyperkeratotic growths resembling the horns of animals in shape and hardness. Recently, we observed a typical case of cutaneous horn in a 13-year-old child. He had a finger-tip sized, yellow-brown, hard, protruding tumor with surrounding erythema on the right little finger for 2 years. On microscopic examination, the biopsy specimen from the squamous epithelium of tbe base showed a typical verruca vulgaris. Total excision and skin graft were performed under general anesthesia.

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.

BACKGROUND: Herpes zoster(HZ), caused by reactivation of latent varicella-zoster virus, is manifested by dermatomal distribution of skin rashes, acute pain and post-herpetic neuralgia by pathologic involvement of the sensory ganglia. Low-energy laser(LEL) deliver a small amount of energy without elevation of the tissue temperature. LEL is reported to have various biologic effects such as anti-inflammatory, analgesic, regenerative, antiallergic, immunocorrective, and antibacterial effects. OBJECTIVE: We attempted to evaluate the therapeutic effect of LEL on an acute phase of HZ. METHODS: A total of 60 patients with acute HZ were enrolled in the study. The control group(30 patients) received medications including analgesics, antihistamine, and topical care without LEL irradiation. The experimental group(30 patients) were irradiated with LEL daily for 7 days in addition to the same kinds of medications for the control group. The efficacy of LEL irradiation for HZ was assessed by analyzing changes in skin rashes, pain scores, and postherpetic neuralgia.

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.
