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.

Dedifferentiated chordoma is a rare pathologic entity presenting an additional sarcomatous component in otherwise classical chordoma. It has been also emphasized that this neoplasm is classified as a distinct entity because of its different clinical settings and aggressive behavior. Dedifferentiation is a peculiar phenomenon but its histogenesis has remained controversial. A 50-yera-old man developed a huge tumor mass in the retrorectal, presacral area, featured with two histological components. The one was a typical chordoma accounted for approximately 60% of the mass and the other was made up of highly cellular, plemorphic, undifferentiated tumor cells, reminiscent partly to the cells of plemorphic malignant fibrous histiocytoma. Ultrastructural features and immunoreactivity against cytokeratin, S-100 protein and alpha-1-antichymotrypsin in both portions support that histologically different components of this neoplasm derive from the same origin. To our knowledge, this is the first case of dedifferentiated chordoma in Korea.

Nodular fasciitis represents reactive fibroblastic or myofibroblastic proliferative lesions which may be misdiagnosed as sarcomas due to the rich cellularity, mitotic activity and variant morphologic pattern. It arises in the subcutaneous tissue, skeletal muscles, and fascia. Uncommon clinical and pathological variants of nodular fasciitis, such as intradermal, intravascular, cranial, ossifying, parosteal and proliferative fasciitis, have been described. We present a 23-year-old man with a one year history of a 2x1.5cm sized hard tender nodule on the scalp which is partially depressed at the margin. Histological examination revealed clusters of spindle cells in a myxoid background, chronic inflammatory cells and extravasated red cells in the dermis. Immunohistochemically, the spindle cells showed positivity of vimentin or smooth muscle actin, and negativity of desmin or S-100 protein. The staining results support its myofibroblastic origin. There is no involved bony lesion on the brain computed tomography (CT). Therefore we report a rare case of intradermal fasciitis arising on the scalp.

Localized cutaneous leishmaniasis is a chronic ulcerative, usually self-limiting skin disease, and one of the major tropical diseases. This disease is caused by an infection of genus Leishmania, transmitted by a sandfly, and there are some cases of cutaneous leishmaniasis in Koreans after travelling abroad in endemic areas, such as the Middle East and Africa. We report a case of localized cutaneous leishmania in a 70-year-old native Korean man without history of a trip abroad.

Fusional amplitudes can be measured using various clinical techniques and targets. But the vergence ranges are different according to the used instruments and the environmental conditions. Currently, measurement with the prism is usually llsed but this method have wide vardabele ranges by the used targets and environmental settings. The authors measured the vertical and horizontal fusional amplitudes of 135 normal Korean men with rotary prism in a well-lit office and compared the group using dim light targer with the group using small letter target. In the group using dim light target, true far convergence value was 14.67 +/- 6.24 delta, true far divergence was 6.64 +/- 3.48 delta, true near convergence was 24.96 +/- 7. 33 delta, true near divergence was 11.05 +/- 5.13delta, far vertical vergence was 2.93 +/-0.95 delta, and near vertical vergence was 3.40 +/- 1.15 delta, There was no statistical differences among are groups(p>0.05), and between the groups using small letter target and dim light target in true near and far convergence amplitudes (p>0.05). This study shows that the method using dim light target is simple and valuable method in measuring the fusional vergences.

Esophageal involvement by malignant lymphoma is extremely rare. A case of follicular lymphoma of the esophagus, misdiagnosed as focal lymphoid hyperplasia (pseudolymphoma) in a 72-year-old man is presented. The esophagogram revealed diffuse narrowing of the lumen in the middle and distal portion without ulceration. The resected esophagus showed mural thickening without any remarkable mucosal change. Microscopically, the esophagus showed scattered follicular lymphoid aggregates in the submucosa, extending into periadventitial fat tissue. Most follicles were devoid of germinal center and consisted of loosely aggregated small cleaved cells without atypia. The surrounding stroma of the submucosa showed dense fibrosis entrapping the infiltrating small lymphocytes in a "indian-file" appearance. There were some reactive follicles with germinal center. In the lamina propria, many plasma cells and a few eosinophils were infiltrated. The gene rearrangement study showed rearranged band for Jk probe which confirmed monoclonal B-cell nature of infiltrated small lymphoid cells. The small cleaved lymphocytes arranged in follicles were positive for L26 and bcl-2 protein. This case demonstrated the necessity of immunophenotypic and gene rearrangement study in the diagnosis of pseudolymphoma in the digestive tract.
