It has been generally assum d that eccrine poroma arises from acrosyringium, the epidermal sweat duct unit. Eccrine poroma mainly involves the non hairy surfaces of t,he skin, but it has also been found on hair-bearing areas. One of the characteristics of this structure is absence of melanocytes and melanin granules arnong its cells. However, a complete absence of melanocytes and melanin granules in eccrine poroma is not invariable and a few reports of such an occurrence have been presented. The authors report herein a case of unusual and rare eccrine poroma. The eccrine poroma had melanin pigment and melanocytes, was pedunculated and occurred on the parietal scalp which was the unusual site of involvement. The eccrine poroma was also combined with a pedunculated congenital melanocytic nevus on the supraauricular scalp. (Kor J Dermatol 1997;35(1): 169-173)

Necrolytic migratory erythema is a rare, distinctive, necrotizing cutaneous eruption usually associated with glucagonoma, an alpha-cell tumor of the pancreas. Other clinical features include ane- mia, diabetes mellitus and weight loss. However, it also occurrs without the pancreatic glucagonoma. So this rare condition is called pseudoglucagonoma syndrome, and has been described in association with chronic hepatic diseases, malabsorption with villous atrophy, chronic pancreatitis, celiac sprue, hypoproteinemia and odontogenic infection. We report a case of pseudoglucagonoma syndrome induced by malnutrition without glucagonoma. A 28-year-old Korean female was referred to our department complaining of multiple erythematous, desquamative, crusted and erosive patches on the extremities, and diffuse scalp alopecia for 5 years. She also had perianal erosion, angular cheilitis without glossitis, amenorrhea, axillary and pubic hair loss, and weight loss. Six years previously she had had Whipples operation for a pancreatic solid and papillary neoplasm. The laboratory data showed hypoalbuminemia, essential fatty acid deficiency, diabetes mellitus and slightly high levels of zinc and glucagon. A skin biopsy showed irregular acanthosis, epidermal edema and pallor, dyskeratosis, areas of superficial epidermal necrosis and vascular dilatation of the papillary dermis. The patient improved dramatically after intravenous hyperalimentation and oral intake of mediurn chain triglyceride. For 2.5 years she has taken medium-chain triglycerides without any other treatment, and no side effects on recurrence has been observed. (Kor J Dermatol 1997;35(3): 593-599)

Background: The authors did not find any study about erythrasma in Korea, where as there are several studies about the incidence and bacteriology of erythrasma in some areas. Failure to differentially diagnose the clinical entities of tinea pedis versus erythrasma can lead to mistreatment and disability because of the clinical similarities. Objective : This study was carried out to investigate the incidence of erythrasma according to the seasons and sites, to determine the useful culture media, and to evaluate the antibiotic sensitivities and the treatment responses. Methods : The incidence of erythrasma was investigated among the unselected dermatologic patients. The axillae, groins and toewebs were examined under Wood's light. The scale showing characteristic coral-red fborescence was Gram-stained and Corynebacterium minutissimnm was cultured using Loeffler slant media, Brucella blood agar plates and usual blood agar plates. Results : Clinical erythrasma was found in 26.7% of the 240 patients examined. The incidences of erythrasma in summer and fall were higher than winter. In the bacteriologic study Gram positive cocco-bacilli were found in all erythrasma patients and Corynebacterium minutissimum was cultured and identified in 24 0%. Most of cultured causative organisms were sensitive to usual antibiotics in the clinical uses. The average interval from the oral administration of erythrasma to the loss of coral-red fluorescence was 4.1 weeks, and the patients in severe erythrasma group were needed more time(2.2 weeks) for clinical improvement than the patients in mild one. Conclusion : Erythrasma is common in the dermatologic patients and it is important to differentially cliagnose the clinical entities of tinea pedis versus erythrasma.
