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.

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.

Maligant melanomas of the oral or nasal cavity, and the vulvovaginal area are relatively common among the melanomas of non-ocular mucosa. But, primary malignant melanoma arising in the mucosa of the palatine tonsil is rare. We present a case of primary malignant melanoma arising in the mucosa of the palatine tonsil. A 36-year-old male was admitted for evaluation of a recurrent sore throat. Tonsillectomy was performed on the basis of clinical suspicion of chronic tonsillitis. Grossly, the left tonsil was focally dark. Microscopically, the tonsillar mucosa was diffusely infiltrated with tumor cells. Tumor cells revealed numerous melanin pigments. Intraepithelial nests of tumor cells were noted, but pagetoid spread of tumor cells was not found. Tumor cells were positive for S-100 protein and HMB45 stain. There was no evidence of melanoma in the skin or eye.

A well-differentiated extraskeletal osteosarcoma is very rare, and only seven cases have been reported in the English language clinical literature. We report an additional case of this rare tumor. A 71-year-old man had noticed a mass in the left pubic area for ten years. A CT scan demonstrated the presence of a lobulated calcified mass within the soft tissue. A 5 cm-sized well-circumscribed mass was excised. Histologically the tumor was composed of mature collagenous tissue and bony trabeculae rimmed by osteoblasts. After 43 months, the tumor recurred at the same site and was re-excised. The re-excised tumor contained focal areas of higher cellularity and atypism. We believe that this is the first case of well-differentiated extraskeletal osteosarcoma reported in Korea.

Eczema herpeticum is a herpes simplex virus (HSV) infection with disseminated skin involvement superimposed on a pre-existing dermatosis such as atopic dermatitis, neurodermatitis, pemphigus vulgaris and Darier's disease. We report a case of eczema herpeticum by HSV-1 infection confirmed by polymerase chain reaction in a 20-year-old man associated with Darier's disease.

Congenital melanocytic nevi rarely develop depigmentation, and only a few cases have been reported in the literature. We, herein, present a case of congenital melanocytic nevus which has undergone progressive involution in association with vitiligo. A 23-year-old man had a dark brownish patch partially surrounded by the depigmented patch on his mid back. He also had multiple depigmented patches on his trunk and neck, which had developed since the age of 5. Histopathologic examination from the dark brownish patch adjacent to the depigmented area showed typical findings of compound nevus with a mild perivascular lymphocytic infiltration. TUNEL staining from the same lesion demonstrated many strong positive epidermal basal cells as well as dermal nevus cells, indicative of apoptosis.
