TESTIS - Chronic epididymo-orchitis

The central feature here is a cavity containing purulent material, walled off from the rest of the tissue by a rim of granulation tissue and fibrous tissue. The testis is compressed to a semi-lunar shape, and there is obvious scarring in the head of the epididymis.
This man was admitted to hospital at the age of 77, with pain in his hip following a fall. No fracture was demonstrated, but he was diabetic and had had a previous stroke. He had also a carcinoma of the bladder. He stayed in hospital for some time and, while there, developed an epididymo-orchitis, which led to the removal of the affected area. No organisms appear to have been isolated from the lesion, and there was no histological evidence of tuberculosis.
