متن کاملA transplantable spontaneous chloroleukemia in the Wistar rat.
Spontaneous chloroleukemia occurred in three adult members of a colony of Wistar rats. The chloroleukemia from one of these rats has been maintained in random-bred Wistar rats by inoculating tumor cells from leukemic donors into suckling rats. This report describes the course and manifestations, hematology, and pathologic changes of this transplantable chloroleukemia through ten serial subtrans...
متن کاملSpontaneous malignant craniopharyngioma in an aged Wistar rat
Craniopharyngiomas are extremely rare epithelial tumors of the sellar region in human beings and domestic and laboratory animals.

متن کاملSpontaneous Subcutaneous Sarcoma in a 50-week-old Male Wistar Hannover GALAS Rat
A subcutaneous mass was noted in the abdomen of a 50-week-old male Wistar Hannover GALAS rat. Histologically, the tumor was composed of vimentin-positive small round cells with scant cytoplasm arranged in a trabecular, sheet or pericytoma-like pattern and spindle cells arranged in a bundle pattern and vimentin-negative round cells proliferating in an island-shaped pattern.

متن کاملSpontaneous infarcted adenoma of the mammary gland in a Wistar Hannover GALAS rat
Spontaneous massive infarction of mammary gland tumors has been reported to occur infrequently in humans. A subcutaneous mass (18 × 17 × 10 mm) was observed in the right axilla extending to the chest region of a 110-week-old female Wistar Hannover GALAS rat. Histopathologically, a well-circumscribed mass with lobular structures was present in the subcutis. Most of the mass was occupied by exten...
