A few cases of a dermatosis characterized by "music box spine" keratotic papules limited to the palms and soles have been reported. There have been several names for this dermatosis The Most commonly incorporated term is porokeratosis, but Osman et at suggested the name "spiny keratoderma of palms and soles" because the clinical, histologic and electron microscopic features of this lesion are distinct from porokeratosis. We report a case of spiny keratoderma on the digit showing a single lesion, as a variant of the classic spiny keratoderma of palms and soles.

BACKGROUND: In our previous report, we observed the increaseed epidermal glucose concentrations and decreased hexokinase actiuities of diabetic patients which were ciimpared to those of normal individuals. And we considered that, there were some derrangement of lipid metabolism and glycolysis of diabetic epidermis. OBJECTIVES: This study wns planed to prove the above possible changes of lipid metabolism and glycolysis of diabetic epidermis. METHODS: The epidermal enzymatic activties of glucose-6-phophate dehydrogenase(G6PDH), phosphofructokinase(PFK), 1-glycerophosphate dehydrogenase(GOPDH) and b-hydroxybutyryl CoA dehydrogenase(HBDH) were assayed in the skin samples obtained friom diabetic patients and normal individuals by the fluorometric: method. RESULTS: Teh epidermal PFK activities of diabetic patients were decreased(3.49+1.35(mmole/hr/kg dry weight)) compared to that of normal individuals(5.00+0.56(mmcle/hr/kg dry weight))(p<0.05). The epidermal HBDH activities of diabetic patients were decreised(0.28+0.10(mole/hr/kg dry weight)) compared to that of normal individuals(0.49+0.20(mole/hr/kg dry weight)(p<0.01). The mean epidermal G6PDH activity of diabetic patients was decreasec. compased to that of normal individuals, but there was no statisical significance. The mean epidermal 3OPDH activittes of diabetic patients and normal individual; showed no significant difference. CONCLUSION: We consider that the decreased epidermal HBDH actiities of diabetic patients can decrease keton body formatiori, and the abnormal glycolysis can exist in the diabetic epidermis because the decreased enzymatic activities of diabetic epidermal PFK may decrease the velocity of glycolysis.

Primary Cutaneous Neuroendocrine Carcinoma(CNEC : or Merkel Cell Tumor) usually occurs as a solitary tumor in middle aged to elderly individuals. This tumor may occur on any layer of the skin but the most frequent location is in the dermis. Electron microscopic studies reveal that the tumor cell contains round, dense core granules similar to epidermal Merkel cell and other cells of the neural crest derived APUD system. We describe the clinical, histological, electron microscopic, immunohistochemical observation of a case of primary CNEC in a 66-year-old female and discuss the theories regarding the histogenesis of this unusual tumor.

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.

A 53-year-old man developed some erythematous follicular macules accompanied with tingling sensation on both shoulders. Histologic finding showed a dense lymphocytic infiltrate around the infundibular portion of the follicle, where separation of the dermoepidermal junction was seen. The insect, obtained from the skin lesion, was identified as a larva of an Ap- hid
