Electron Microscopic Study in Tinea Versicolor: Structural Changes of Melanosomes Accompanying the Hyperpigmented and Hypopigmented Lesions / 대한피부과학회지

Electron microscopic examination of specimens from lesions of eight patients with hyperpigmented and six patients with hypopigmented tinea versicolor and from unaffected skin in each patient was performed. The results are summarized as follows; 1. In hyperpigmented lesions, melanosomes are larger and more singly dispersed than in unaffected skin. 2. In hypopigmented lesions, melanosomes are smaller and less singly diepersed than in unaffected skin. 3. Number of total melanosomes in hyperpigmented and hypopigmented lesions was not different from in unaffected skin.

Leukemia Cutis in a Patient with Acute Lymphocytic Leukemia / 대한피부과학회지

Leukemia cutis, skin lesions in leukemia, are clinically divided into specific and nonspecific types. Specific skin lesions demonstrate malignant cell infiltrate when the biopsy is done. We have encountered a typical case of specific skin lesions of leukemia cutis associated with acute lymphocytic leukemia in a 18-year-old male patient. There were multiple, pinhead to rice sized, skin colored to lemon yellow colored, discrete papules on the face, neck and trunk. A review of the literature is presented with a brief discussion of this case.

A Case fo Cryptococcosis with Cutaneous Manigestations / 대한피부과학회지

Cryptococcosis is an acute, subacute or chronic infectian caused by the encap sulated yeast Cryptococcus neoformans. The case of Cryptococcosis is a 2 5/12 year-old boy with involvement of the skin, lungs, liver, spleen, lymph node and central nervous system is reported. He has suffered from fever, nausea., vomiting and multiple skin lesions for a month. Thcre were various cutaneous lesions consisting of papules, pustules, nodules, crusts and ulcers on the scalp, face, back, buttocks and both extremities. Diagnosis was confirmed by the clinical characteristics, histopathologic findings and culture of the C. neoformans from cerebrospinal fluid and marcerated skin tissue. He was successfully treated with combination of Amphotericin B and 5-fluorocytosine.

A Case of Histiocytic Medullary Reticulosis with Cutaneous Lesions / 대한피부과학회지

Histiocytic medullary reticulosis is a rare, uniformly fatal, acute disease of the reticuloendothelial system. The disease is associated with fever, malaise, weakness, weight loss, lymphadenopathy, hepatosplenomegaly, jaundice, and purpura. Common laboratory findings are severe anemia, leukopenia, and thrombocytopenia. A 49-year-old male patient is described who had multiple purple nodules and tumors in the skin. A biopsy taken from a skin lesion showed a diffuse proliferation of atypical histiocytes in the dermis and subcutaneous tissue.However, erythrophagocytosis of these atypical histiocytes was not seen.
