The goals of the evaluation is to identify; 1) potentially correctable conditions, 2) irreversible conditions but are amenable to ART using male partner sperm, 3) irreversible conditions not amenable to ART, fro which donor IUI or adoption are possible options, 4) life- or health threatening conditions that may underlie infertility and require medical attention and 5) genetic abnormalities that may affect offspring if ART is employed.

A 55 year old male complain right shoulder pain and right upper quadrant pain about three months. He was a heavy alcoholism. Highly selective angiography, CT scan and operation findings suggest primary malignant neoplasm of the liver. Right hepatic lobectomy and partial diaphragmectomy was done under impression of heaptocellular carcinoma. The specimen measured 15x11x9 cm and disclose relatively hard and nodular mass devoid of cirrhotic changes. Cut surface show unilobar large mass measuring 11x8x6 cm and bearing brightly yellow discoloration and multifocal hemorrhagic necrosis. Histological characteristics were diffuse proliferation of large neoplastic cells with ample cytoplasm, containing granular materials, erythrophagocytosis, neutrophagocytosis and hemosiderin pigments. Atypical and bizarre mitosis and multinucleated giant cells bearing abundant erythro and neutrophagocytosis were frequently seen. The large or vesicular nuclei were irregular, with occasional deep indentations and revealed sharply defined nuclear membrane, coarse chromatin and conspicious nucleoli. Ultrastructurally the cytoplasm of neoplasltic cells had lysosomal granule, phagolysosome, phagocytized material and residual bodies. Immunohistochemical stains for alpha 1-antitrypsin, alpha 1-antichymotrypsin, vimentin and lysozyme showed positive reactions, but, alpha fetoprotein, cytokeratin, S-100 protein, factor VIII, complement 3 receptor and carcinoembryonic antigen were negative. Alpha-naphtyl acetate esterase activity in paraffin embedded tissue ribbon showed negative reaction. These findings show compatible with primary malignant lymphoma, true histiocytic type, (histiocytic sarcoma, Kupffer cell carcinoma) of the liver.

Posttransplant lymphoproliferative disorders (PTLD) is an infrequent but serious complication of transplantation. Previous studies have suggested the terms of reference, "early PTLD" (referring to PTLD that occurs within 1 year of transplantation) and "late PTLD" (PTLD that occurs after 1 year). Early PTLD generally involves a single organ or nodal region and often responds favorably to a decrease in immunosuppression. Late PTLD tends to be disseminated, responds less frequently to a decrease in immunosuppression, and has a dismal prognosis. We encountered a diffuse large B-cell lymphoma in a 44-year-old man who underwent kidney transplantation over 10 years ago, in 1995. In situ hybridization for Epstein-Barr virus showed positive results in tumor cell. With decreased immunosuppressants and chemotheraphy, he is currently in complete remission.

Peritonitis in continuous ambulatory peritoneal dialysis is a major cause of technical failure in peritoneal dialysis. The major pathogen is gram positive bacteria, and other main pathogens include gram negative bacteria, mixed infection and fungal infection actively involved in the order named. Coagulate-negative Staphylococcus, Streptococcus, Staphylococcus aureus and Enterococcus cause most of the gram positive bacterial infections, and cases with other pathogens are very rare. We hereby report a case of peritonitis by Listeria Monocytogenes that was not responsive to the usual antibiotics for CAPD-associated peritonitis. A 58-year-old male who has been treated with CAPD for 17 years visited our hospital for abdominal pain, fever and turbid peritoneal fluid. He was diagnosed as diabetes mellitus 20 years ago. White blood cell and neutrophil count increased at the initial peritoneal fluid analysis, so we diagnosed him as CAPD-associated peritonitis. Antibiotic therapy was initiated with intraperitoneal injections of cefazolin/tobramycin, which were soon changed to vancomycin/ceftazidime. However, vancomycin/ceftazidime regimen was also proven ineffective. On the sixth hospital day, L. Monocytogenes was cultured in the peritoneal fluid sampled on the first visiting day. So we accordingly changed the antibiotics for ampicillin/sulbactam, which led to clinical and laboratory improvement. In the cases of CAPD associated peritonitis in immunosuppressive patients such as the elderly, caused either by diabetes or by taking immunosuppressive agent, if they do not respond to the usual antibiotics, we should consider the possible infection by unusual pathogens. Gram positive rod in peritoneal fluid is a supporting evidence of peritonitis by L. monocytogenes.

Pleomorphic (undifferentated) carcinoma is a rare histologic type of carcinomas of the gallbladder and an atypical carcinoid is thought to be an intermediated type between carcinoid tumor and small cell carcinoma. Dense core "neurosecretory" granules can be found in the above mentioned tumors. We experienced a case of a double tumor of the gallbladder in a 51-year old male patient. Grossly, a large solid mass, about 5.0 cm in diameter, was found in the fundic portion and the neck portion also had a small 1.5 cm-sized polypoid mass. Microscopically, these lesions had features of pleomorphic carcinoma and atypical carcinoid, respectively. Immunohistochemically, they manifested reactivity for neuron specific enolase. Ultrastructural study revealed neurosecretory granules in the cytoplasms of tumor cells of the fundic and neck masses. Although light microscopic features of these tumor masses are quite different, we consider that these tumors represent a spectrum of neuroendocrine differentiation.
