Plain-English summary

A 13-year-old mixed breed dog had trouble urinating and was found to have blood in his urine, along with a nodule at the base of his penis. After surgery to remove the penis, the vet diagnosed him with osteosarcoma, a type of bone cancer. Unfortunately, despite the surgery, the cancer returned within two months, leading to the difficult decision to euthanize him. This case is notable as it is the first reported instance of osteosarcoma occurring in the penile bone.

Abstract

A 13-year-old mixed breed dog was presented with difficulties to urinate, blood in the urine and a nodule at the root of the penis. The penis was completely resected, and an osteosarcoma of the penile bone was diagnosed. Radiographically, there was no evidence to suggest tumours in other bones or distant metastases. The dog was euthanized as a consequence of tumour recurrence after 2 months. This is believed to be the first reported case of a primary osteosarcoma of the penile bone.
