Testicular histopathology in juvenile rat toxicity studies

Histopathology of Incidental Findings in Beagles Used in Toxicity Studies

The purpose of our publication is to widely communicate the pictures of spontaneous findings occurring in beagles. Spontaneous arteritis occurs commonly in beagles. Frequent sites of arteritis are the heart, spleen, pancreas, epididymis and spinal cord. Morphological similarities between spontaneous and drug-induced arterial lesions may cause confusion when evaluating vascular toxicity of chemi...

Testicular toxicity of thiram in rat: morphological and biochemical evaluations.

Tetramethylthiuram disulphide (Thiram), a dithiocarbamate fungicide was administered to male rats through gavage at dose 5, 10 and 25 mg/kg/day for 30, 60 and 90 days. A significant increase in relative testes weight (GSI) was observed at dose (25 mg/kg/d) after 90 days exposure, associated with mild pathomorphological changes. This included degeneration of seminiferous tubules with sloughing o...

Synchronous Bilateral Testicular Tumors with Different Histopathology

A 40-year-old male presented to our outpatient department with the chief complaint of a painless mass on his right testis with gradual size increase over the past two months. Physical examination and ultrasound revealed a firm and nontender mass both on the right and on the left testis. The only elevated biomarker was b-hcG (24,7 mIU/mL) and computer tomography (CT) did not reveal any pathology...

Histopathology of Incidental Findings in Cynomolgus Monkeys (Macaca Fascicularis) Used in Toxicity Studies

The purpose of our publication is to widely communicate pictures of spontaneous findings occurring in cynomolgus monkeys. Focal lymphoplasmacytic infiltration is commonly seen in the general organs. The frequency and severity of these lesions may be influenced by the administration of drugs with an effect on the immune system. Lymphoplasmacytic infiltration in the lamina propria of the stomach ...
