Biliary cystadenoma in a striped skunk (Mephitis mephitis)

MEDIASTINAL LYMPHOMA AND CHYLOTHORAX IN A STRIPED SKUNK (MEPHITIS MEPHITIS)

Tumors are infrequently reported in skunks, with only a few case reports published in the literature. Chylothorax associated with mediastinal lymphoma was diagnosed in a captive 7-yr-old male striped skunk ( Mephitis mephitis ). The animal presented with anorexia and apathy. Supportive care and prednisolone improved the animal's clinical status for 2 wk preceding its death. Histopathology supported the clinical findings, and the tumor was classified as a mediastinal non-Hodgkin lymphoma, stage 2b, which has not been documented in the literature.

A primary retroperitoneal seminoma invading the kidneys of a cryptorchid dog

The relationship between cryptorchidism and testicular tumors has been well established in canines, and the tumor has been proposed as a model for studying its human counterparts. Herein we report canine malignant retroperitoneal seminoma in a 4-year-old castrated Basset hound, most likely without testicular involvement, similar to that of the classic seminoma of humans.
