In about 20 to 30 percent of cases with organoid nevus (nevus sebaceus), benign and/or ma-al lignant tumors of the epidermis and adnexae may develop. We describe a 71-year-old woman with sebaceous carcinoma and basal cell epithelioma developed in organoid nevus.

Infection-induced panniculitis develops either through direct inoculation or as a manifestation of sepsis. However, it has rarely been considered as a disease entity within broader context of panniculitis. Moreover, panniculitis associated with a cardiac abscess without the evidence of sepsis has not been reported. We describe a case of infection-induced panniculitis associated with a cardiac abscess. We suggest that infection should be considered as a potentially important etiology of panniculitis, especially in the case of immunosuppression, and in such a case, meticulous efforts should be done to find the focus of infection.

We report a case of Winkelmann granuloma in a 63-year-old man. nstopathological findings of the biopsy specimens from the lesions of the ear, finger and iliac crest area were compatible with Winkelmann granuloma. Winkelmann granuloma is a rare disorder showing an association with systemic immunoreactive disorders. Although our patient did not have any definite systemic disease, he had characteristic clinical and histopathological findings of Winkelmann granuloma, arthralgia, an elevated erythrocyte sedimentation rate, positivity to the rheumatoid factor and antinuclear antibodies. Therefore, we believed that he was strongly suspected to have an unclassifiable systemic immunoreactive disease.

We report a case of histiocytoid hemangioma (angiolymphoid hyperplasia with eosinophilia) in a 60 year-old female patient who was effectively treated with dapsone. The therapeutic effect of dapsone may support the hypothesis that immunologically mediated reactive process plays a role in the pathogenesis of histiocytoid hemangioma.

BACKGROUND: Actinic granuloma is an annular inflammatory reaction that develops in skin that has had long-term sun-exposure. OBJECTIVES: The purposes of this study were aimed to characterize the clinical and histopathologic features of actinic granuloma. METHODS: Examinations were performed on eight patients with actinic granuloma regarding the age, sex, duration, clinical morphology, distribution, associated diseases, and treatment and course. Histo-pathologic studies of ten specimens obtained from eight patients were performed with special stains, such as Verhoeff-van Gieson, Gomori-Methenamin silver and alcian blue.

BACKGROUND: Labial pigmented lesions include labial melanotic macule, ephelids, lentigo, venous hemangioma, amalgam tattoo, junctional nevus, Peutz-Jeghers syndrome, Addison's disease, Laugier s disease, and superficial spreading melanoma. OBJECTIVES: The purpose of this study was aimed at investigating the clinical and histopathological characteristics of labial melanotic macule during the past 10 years. METHODS: Clinical information of 49 patients with pigmented lesion of the lips diagnosed in Asan Medical Center from 1989 to 1999 was obtained from the medical records and clinical follow-ups. We re-evaluated all the biopsy specimens obtained from the patients. RESULTS: Twenty-six patients with labial melanotic macule were enrolled in this study. There were 16 women and 10 men. Age at onset varied from 20 to 65 years in women and from 28 to 68 years in men. The duration of the lesion ranged from 4 months to 12 years (mean, 4.5 years). The majority of patients had solitary lesions on the lower lip. Histopathologic examination of biopsy specimens showed increased pigmentation of the basal layer, mild acanthosis without elongation of rete ridges, and scattered melanophages in the dermis. CONCLUSIONS: We suggest that labial pigmented lesions appearing in adults should be biopsied and labial melanotic macule should be diagnosed after the histopathological examination.

Actinic granuloma (O'Brien) is an annular inflammatory reaction that develops in skin after long-term sun-exposure. Anetoderma is characterized by discrete skin lesions that appear to be loose and wrinkled. The primary type arises in clinically normal skin, and the secondary type appears in lesions of other disorders. We describe a case of anetoderma that developed on the neck, both arms and calves, and showed histopathological findings of actinic granuloma.

Sarcoidosis is a systemic granulomatous disease of undetermined etiology and pathogenesis that involves the skin and many of the internal organs. It involves any organ of the body; how-ever, the most common sites are the lung, lymph node, skin, and eye. Psoriasiform eruption is a rare morphologic manifestation of sarcoidosis. We report herein a case of 36-year-old man with psoriasiform papules on the elbows, forearms and knees of 5-year duration. Histopathologic examination revealed sarcoid granuloma throughout the dermis. This is the second case of psoriasiform sarcoidosis in Korea.

Sneddon's syndrome consists of widespread livedo reticularis and ischemic cerebral manifestations. We report a case of a 70-year-old Korean woman with extensive livedo reticularis, hypertension, positive laboratory results for antinuclear antibodies and the lupus anticoagulant test, and idiopathic Parkinson's disease.

Cutaneous mesenchymal hamartoma (CMH) is a very rare disease which most often presents itself at birth and is composed of collagen fibers, immature fibroblasts, fat cells, blood vessels, and mast cells. Until recently, only two cases have been reported. Thus, the clinical and histopathological findings have been unsettled. We describe three cases of cutaneous mesenchymal hamartoma with different clinical findings, discuss its pathogenesis, and suggest that CMH is a distinct disease entity.
