Serous cystadenoma of the pancreas, also known as microcystic adenoma or glycogen-rich cystadenoma, is an unusually benign tumor. It is usually large and composed microscopically of many small cysts lined by small, cuboidal or flattened cells containing abundant glycogen. It has been suggested that serous cystadenoma probably arise from the ductular cells or centroacinar cells. Herein, we report on a case of serous cystadenoma of the pancreas in a 55-year-old female. The tumor, measuring 13.5x11.5x10.0 cm, was located in the head of the pancreas and the cut surface revealed a sponge-like appearance due to innumerable tiny cysts containing clear serous fluid. Microscopic analysis showed cystic spaces lined by cuboidal cells with intracytoplasmic glycogen.

Cystadenomas are benign neoplasm in which the epithelium demonstrates adenomatous proliferation. Several morphologic variants of cystadenomas have bean described, including papillary-oncocytic, mucous, and seromucous subtypes. Cystadenomas arising from salivary glands are very rare and seromucous cystadenoma of parotid gland has not been reported in Korea so far. Cystadenomas of the parotid gland usually Present as asymptomatic slowly growing mass and those of the minor salivary glands produce smooth nodules that may be compressible. We performed a superficial parotidectomy in a patient with a seromucous cystadenoma. This may be the first report of seromucous cystadenoma of carotid gland in Korea.

Job's syndrome is an inflammatory skin disease characterized by (1) severe eczema, (2) recurrent staphylococcal infections of the skin and sinopulmonary tract, (3) cold subcutaneous abscesses, and (4) high serum IgE levels. We describe a 55-year-old woman with long-standing atopic dermatitis-like eczema, recurrent abscesses, and a high level of serum IgE. We suspected this case as Job's syndrome.

Congenital self-healing reticulohistiocytosis (CSHRH) is a rare Langerhans cell disorder showing spontaneous resolution within 3-4 months. By electron microscopy, the identification of many Birbeck granules and laminated dense bodies in the infiltrated cells is mandatory for the diagnosis of CSHRH. We describe a case of congenital self-healing reticulohistiocyt~osis in a 4-month-old male infant.

A total of 672 surgically resected gastric carcinomas were reviewed, and fourteen cases(2.1%) of "gastric carcinoma with lymphoid stroma" were identified. The tumor was located mostly in cardia and body portion(86%). Thirteen patients one was lost to follow up were alive without recurrence of tumor. Grossly, this carcinoma was characterized by an expanding growth pattern or a multinodular pattern. Histologically, this carcinoma showed an irregular trabecular and alveolar arrangement and densely infiltrated lymphoid cells with lymph follicles. The tumor cell nests were widely separated by non-desmoplastic lymphoid stroma. On immunohistochemical study, T cells were evenly distributed throughout the tumor lesion with intimate contact with individual carcinoma cells, but B cells were mainly present within the germinal centers of lymph follicles. Thus, the organized immune response combined with cell mediated and humoral immunities against the carcinoma cells may be a defense mechanism of the host in this type of gastric carcinoma.

The expression of p62"' and p2l can be seen in many solid tumor, but the pattern and incidence of expression were different according to organ, countries, and examiners, thus it is not definitely defined. Total 67 colorectal carcinoma in paraffin sections are analysed by immunohistochemically for evaluation of the p62and p21- expression according to the age, sex, chief complaints, location, differentiation, modified Dukes stage, using the specific monoclonal antibodies. The results were summarized as follows : The age of patients ranged from 32 years to 82 years. The mean age was 57.6 years. The expression of p 62y' and p21 was not correlated with age. Male was 29 cases(43.3%) and female was 38 cases(56.7%). The male to female ratio was 1:1.31. The and 95.0% in moderately differentiated adenocarcinoma, 90.0% and 90.0% in poorly differentiated <,;, adenocarcmoma, 100.0% and 100.0% in mucinous carcinoma. The positive rate of p62!and and p2l' was 94.1% and 88.2% in Dukes stage B,, 96.0% and 96.0% in Dukes stage B,, 100.0% and 100.0% in Dukes stage C,, 100.0% and 88.9% in Dukes stage C, and 100.0% and 100. o% in Dukes stage D. The expression of p62 y' in metastatic colorectal carcinoma showed diffuse and strongly positive reaction than primary colorectal carcinoma. The expression of p21 in primary colorectal carcinoma showed diffuse and strongly positive reaction than metastatic colorectal carcinoma.

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.

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.
