A case of lymphoepithelial carcinoma occurring in the left submandibular salivary gland is presented. Histologic features of this rare malignancy are described in detail. This unusual carcinoma has been described frequently in Eskimos and is usually located in the parotid gland. The raised serum IgG to Epstein-Barr virus capsid antigen suggests a causal(More)
UNLABELLED Clear cell carcoma of the kidney is a distinct, highly malignant pediatric neoplasm. Its occurrence in adults is extremely rare and the subject of isolated case reports. MATERIAL AND METHODS We report 3 cases of clear cell sarcoma of the kidney in one men and two women between 23 and 65 years old (mean age is 40 years). A radical nephrectomy(More)
We report a case of prostate cancer in 34 year old man presenting with generalized lymphadenopathy mimicking malignant lymphoma without any urinary symptoms. Lymph node biopsy revealed metastatic adenocarcinoma and immunohistochemical stain was strongly positive to prostate antigen (PSA). Serum PSA level was also markedly elevated. Transrectal ultrasonogram(More)
Microcystic meningioma is a distinct morphological variant of meningioma, characterized by loose texture and microcysts with formation of large extracellular spaces containing edematous fluid. The tumor cells have stellate and vacuolated cytoplasm with long cytoplasmic processes. We experienced a case of typical microcystic meningioma occurring in the falx(More)
In the condensed matter physics field, there coexists a pure research field and application field. Therefore it is possible that a source technology is discovered firstly and developed in one laboratory of condensed matter physics. Since the 20<sup>th</sup> century, many evolutionary progress in electronic industry e.g. semiconductor and display industry(More)
Clinically evident metastases of carcinomas to the thyroid gland are rare, particularly from a colorectal primary tumor. We present a case of colonic adenocarcinoma metastatic to the thyroid gland with histopathologic and immunohistochemical findings. A 68-year-old woman with a history of Dukes' stage B colon carcinoma presented a mass in the thyroid gland.(More)
Evidence suggests that multiple molecular events, including alteration of cell cycle regulators are involved in the development and progression of gastric carcinoma. Recently, it has been reported that the expression of p21 and p27, integrating the effects of one or more cell cycle regulators, consequently, acting as a single indicator of several possible(More)
Transpupillary retinal photocoagulations were performed on ten eyes of five pigmented rabbits using a diode laser (Nidek Co., LTD, Aichi, Japan) emitting infrared radiation at 800 nm wavelength. A histological and an ultrastructural study on the treated eyes were done at 1, 3, 5, and 7 days after retinal photocoagulations. The purpose of this study was to(More)
