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.

BACKGROUND: All though the cause of alopecia areata is not known, many studies have recenty focused on the autoimmunity of alopecia areata. OBJECTIVES: The objectives of this study were to detect autoantibodies against hair follicular antigens and compare the autoantibody level before and after treatment of alopecia areata. METHODS: We collected serum from: (a) 7 alopecia areata patients with good therapeutic responses, (b) 5 alopecia areata patients with poor therapeutic responses (c) 5 normal control people. First, we detected the antigens of hair follicles with SDS-PAGE. Secondly we reacted the antigens with the patients' and normal control serums by Western blotting. RESULTS: The follicular antigens were seen in the range of 44kD-57kD. Autoantibodies obviously apparent in patients of alopecia areata but not in the normal control. High concentrations of were Autoantibodies against follicular antigens seemed to be present in the patients with good therapeutic responses and as they had been treated well, the level of autoantiboies has decreased. Autoantibodies, however, were present in small amounts and were almost an changed between before and after treatment in the patients with poor therapeutic responses except for one case. CONCLUSION: There are kinds of autoantibodies against hair follicles in the serums of alopecia areata patients, and the titers of antibodies may be correlated with therapeutic responses.

We report a case of disseminated cutaneous metastatic carcinoma from stomach carcinoma in a 66-year-old male who complained chiefly of widespread cutaneous nodules. He had been admitted to the Department of Internal Medicine for stomach carcinoma. A radiological examination revealed a diffuse stomach wall thickening from the fundus to the antrum, and enlargement of paraaortic and pericaval lymph nodes during an abodominal CT scan. The clinical findings manifested above may suggest cutaneous metastasis from stomach carcinoma. A histological examination of the skin and stomach biopsies showed atypical cells with pleomorphic, hyperchromatic nuclei and bubble-like cytoplasm, which are consistent with poorly differentiated adenocarcinoma. Immunohistochemical stainings showed that these cells were positive for epithelial membrane antigen (EMA), carcinoembryonic antigen (CEA) and low molecular weight cytokeratin.

Pseudocyst of the auricle presents as a non-inflammatory, fluctuant swelling on the upper half or third section of the ear, due to intracartilaginous accumulation of fluid. Histological examination shows an intracartilaginous cavity without an epithelial lining. The etilogy and pathogenesis of this disorder remains unknown, but the lesion is likely to be due to localized de-generation of cartilage. The degenerated cartilage is replaced by a vascular fibrous tissue from which there is serious exudation, and a clinical cystic swelling is formed. We describe in this report three cases of pseudocyst of the auricle, of which one was treated successfully by surgical excision and a pressure dressing, and the others by aspiration and steroid injection therapy. In all cases, the skin lesions had not recurred, and the patients were left with an excellent cosmetic result.

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.
