Malignant acanthosis nigricans is very rare disease. The disease is related with internal malignancy, especially gastrointestinal tract malignancy. Reported occurrence rate of malignant acanthosis nigricans associated internal malignancies are 64% of stomach adenocarcinoma, 27% of other organs of abdomen (liver, gall bladder, small intestine, rectum, uterus, ovary), 9% of non-abdominal organs(breast, lung). We report a case of malignant acanthosis nigricans associated with stomach adenocarcinoma from 20-year-old female and discuss review of literature on a acanthosis nigricans briefly.

The purpose of this study was to examine the frequency of eutaneous disorders in patients with chronie renal failure presently on hemodialysis(HD). The results were as follows. 1. Cutaneous lesions were present in all 78(100% ) patients with chronic renal failure. 2. The frequency of msjor cutaneous problems associated with chronic renal failure was as follows: xerosis(82.1%), pruritus(74.4%), nail changes(74.4%), hyperpigmentation(70.5 % ), xerostomia(42.3'Yo), poor wound healing(37.2%), easy bruisability(30,8%), hypotrichosis(21.896), and purpura(14.1 % ). 3. Cutaneous problems which appeared after the initiation of HD were. appearance of new pigmented nevi or lentigines(9 patients), appearance or aggravation of acne(6), contact dermatitis at AV fistula site(2), gynecomastia(1), extensive flat warts(1), extensive tinea versicolor(1), and extensive vitiligo(1). 4. Among 55 patients with hyperpigmentation, 11 patients reported decreased pigmentation following HD. In 15 patients, hyperpigmentation worsened following HD, and in 9 patients hyperpigmentation first appeared after HD was initiated. 5. Cutaneous disorders favorably affected by HD were as follows: easy bruisability(3/ 24), xerostomia(3/33), gingival friability(2/7), and hypotrichosis(5/17). 6. Poor wound healing and xerosis were not improved by HD. 7. Among 58 pruritic patients, 7 patients were improved after HD, 7 patients became worse during each HD, and 3 patients were not pruritic only for 2 to 3 days after each HD. Four patients experinced pruritus only during each HD. 8. There was no significant statistical difference between the frequency of pruritus and xerosis and the levels of blood urea nitrogen, calcium, phosphorus, and parathyroid hormone.

While most dermal melanocytoses are congenital or have an onset in early childhood, there is an acquired group with a late onset. We describe a case of aldolescent onset, unilateral, macular dermal melanocytosis on the hand. A 16-year-old girl presented with a 10-month history of gray-bluish pigmentation on the right palm and the volar side of the right fourth finger. The light microscopic studies showed spindle-shaped dermal melanocytes. The S-100 protein staining of these cells was positive and CD68 staining was negative. Dermal melanocytosis of the macular type, as observed in our case, is very rare.

Pleomorphic adenoma presenting as primary lesion of the bronchus is very rarely encountered, and in our knowledge only 6 cases have been reported in the literature of the western world, and no case report has been published in Korea. Currently, we experienced a case of bronchial pleomorphic adenoma occuring in a 38 years old woman. On X-ray examination, hazy density in the right upper lobe and emphysematous change in the right lower lobe were noted. A right pneumonectomy was done under bronchoscopic diagnosis of bronchial adeoma. The pathologic examination of the present case showed a polypoid endobronchial tumor, 1.4 x 1.1 cm (with extraluminal portion, 2.2 x 1.7 cm) in the right upper bronchus. The microscopic examination revealed a pleomorphic adenoma showing same morphology as those found in the salivary gland. This case, therefore, was believed to be a genuine example of bronchial pleomorphic adenoma of salivary gland type. We compared this case with 6 cases in the literature.

The clear hidradenoma, generally regarded as an eccrine sweat gland origin, is an uncommon tumor and occurs as a slowly growing, usually solitary nodule. The histologic patterns varies from one tumor to another and in different parts of the same tumor. The histologically variable patterns, therefore, are expressed in various names, including nodular hidradenoma, eccrine acrospiroma, squamous poroadenoma, and solid cystic hidradenoma. During the past 16 years the authors experienced 5 cases of clear cell hidradenoma which were diagnosed by the histopathological examination of the tumor mass removed by surgical excision. Clinical and pathological features were reviewed and the following results were obtained. 1) The mean age was 34 years with a range from 27 to 45 years. Three were male and two female. 2) The chiefr complaint was intradermal or subcutaneous nodules for a period of several years to 15 years. All cases occured as a solitary nodule without a distinct predilection for certain sites. A nodule which situated in the dermis and was accompanied by superficial ulceration was elevated above the skin surface in one case. 3) Grossly, the tumors were relatively well circumscribed and composed of multiloblated masses in 4 cases. They ranged in size between 1.5 and 3.5 cm. 4) Microscopically, all cases disclosed lobulated solid masses separated by varying amounts of collagenous connective tissue. There were often cystic spaces, which were lined by a single row of cuboidal cells in four cases and were bordered by tumor cells in remaining one case. These cysts contained a faintly eosinophilic homogeneous material. On solid portions of the tumor there were two types of cells (clear cell and polygonal cell), the proportions of which varied from tumor to tumor in three cases. The remaining two cases were predominantly composed of clear cells. Tubular lumina which were lined by cuboidal or columnar ductal cells were found in two cases. Areas of squamous differentiation and squamous eddies were seen in one case. Intracytolasmic PAS-positive materials were shown in all cases, but diastase-resistant PAS materials in two cases.

Orbital mesenchymal chondrosarcoma, first described by Luis et. al in 1971, is a very rare tumor of characteristic histologic features. A 21-year-woman was admitted with a 4-month histoiry of rapidly progressive proptosis and visual disturbance. Right orbital exenteration was performed under the clinical diagnosis of orbital calcifying tumor. Grossly, the tumor presented as a multibloblated, circumscribed mass that measures 5.5 cm in the greatest dimentsion. Cut sections resembled ordinary chonrosarcoma. Microscopically, the tumor was composed of undifferentiated mesenchymal cells, interspersed nodules of well differentated cartilagenous tissue, areas of gradual transition from undifferentiated mesenchymal cells to cartilage, and hemangiopericytoma-like areas. A brief summary of the histopathological aspect of this tumor and a review of literature are presented.
