Generalized plane xanthoma is less common and usually involves the eyelids, lateral side of the neck, upper trunk, and extremities. Lesions, however, may appear on any portion of the body. Cutaneous xanthomas may occur in hyperlipidemic and in normolipidemic states. Generalized normolipidemic plane xanthoma is often associated with multiple myeloma, other reticulo-endothelial malignancies and monoclonal gammopathy with unknown significance(MGUS). We wish to report two eases of generalized plane xanthoma associated with IgG monoclonal gammopathy of unknown significance.

Agminated lentigines may be defind as a circumscribed grouping of small pigmented macules arranged in a small or large group, often in a segmental pattern, each macule consisting of a lentiginous epidermal proliferation of melanocytes. We report five cases of agminated lentigines in otherwise healthy persons. Histologic exarnination of the pigmented lesion revealed findings consistent with lentigo simplex.

Lymphangiomas are made up of multiple lymphatic channels lined by benign-appearing endothelial cells. The lesions can occur anywhere in the body but most commonly affect head, neck and axilla. It rarely involves the gastrointestinal tract and particularly lymphangioma of the colon is very rare. Histologically, it is classified three types as simple or capillary, cavernous, and cystic. We experienced three cases of cavernous lymphangioma of the ascending colon. Case 1, 56-year-old male, had lymphangioma accompanied by ulcerating cancer of the cecum. Case 2, 51-year-old female, had lymphangioma of cecum. Case 3, 41-year-old male had lymphangioma at ileocecal valve. All cases could be diagnosed by colonoscopic snare polypectomy.

PURPOSE: Kawasaki disease is notorious for coronary arterial complication which is usually developed as a febrile disease in early childhood. Increased polymorphonucleus(PMN) cell levels in acute phases may be associated with the pathophysiology of Kawasaki disease. We studied the relationship between coronary arterial dilatation and elastase activity which was excreted from PMN cell and roles as an important factor for vasculitis. METHODS: Ten patients diagnosed with Kawasaki disease in Yonsei University Medical Center were examined between November, 2001 and January, 2002. In addition, 15 patients with other febrile diseases were also examined. Echocardiography was done in patients with Kawasaki disease on the first day of admission and four weeks after the onset of the disease. At each time, venous samples were drawn and separated into plasma and leukocytes. In patients with other febrile disease, samples were drawn on admission. Elastase activities in plasma and neutrophil extracts were measured. RESULTS: The significant increased plasma elastase activity, 6.19+/-0.74 U/mL, found in Kawasaki disease patients compared with the other febrile disease patients, 4.86+/-1.17 U/mL(P<0.05). And there was no significance between the above two diseases in terms of the elastase activity in neutrophil extracts. The relationship between initial elastase activity and the coronary arterial complication which was shown in subacute phase wasn't significant. CONCLUSION: Plasma elastase activity was increased in Kawasaki disease significantly, but the initial plasma elastase activity in the acute phase could not reflect the range of coronary arterial complication.

Desmoplastic malignant melanoma (DMM) is an uncommon variant of malignant melanoma featuring a proliferation of spindle cells with pronounced desmopaasia. DMM commonly occurs on the sun-damaged skin such as head and neck in older persons, and it can be associated with lentigo maligna. We report an unusual case of desmoplastic malignant melanoma that developed de novo on the trunk in a young patient.

A umbilical omphalomesenteric duct polyp is the result of incomplete closure of the omphalomesenteric duct, which connects the midgut with the yolk sac of the embryo. It may be associated with underlying embryologic anomalies such as Meckels diverticulum and umbilical enteric fistula, the complications of which may at times be fatal. This rare malformation should be clinically discerned from persistent granulation tissue or pyogenic granuloma. Histologically, it shows a polypoid lesion consisting of ectopic gastrointestinal epithelium with the appearance of gastric, intestinal, or colonic mucosa. We report a case of an umbilical omphalomesenteric duct polyp in an 8-year-old male patient, who had had a bright-red polyp on the umbilicus from the age of 1 month and had not had any other types of underlying abnormalities.
