Carcinoma de glândula hepatóide em prepúcio associado a sarcoma de tecidos moles anaplásico em membro pélvico de cão: relato de caso

Abstract

Malignant neoplasms, also known as cancer, are characterized by rapid and aggressive growth. The presentation of cancer can vary and often has cellular peculiarities depending on its site of origin, such as Soft Tissue Sarcomas (STS), which originate in mesenchymal tissue, and Hepatoid Gland Adenocarcinomas (HGA), which originate in the perianal glands. In this context, the aim of this study is to report the simultaneous occurrence of Hepatoid Gland Carcinoma and a Sarcoma in the same patient, given the rarity of these findings together. A case of an 8-year-old Pitbull dog was described, presenting with a complaint of increased mass in the left pelvic limb, accompanied by pain while walking. The patient underwent consultation, hematological and cytological evaluation, as well as radiographic and computed tomography examinations, which indicated the presence of proliferative cells. With surgical treatment and resection of specimens for biopsy, histopathological examination diagnosed the presence of a hepatoid gland adenocarcinoma in the penile region and a grade III pleomorphic sarcoma in the left pelvic limb.
