Sarcoma Estromal Esplênico em cão da raça Shar-pei: Relato de caso

Abstract

Sarcomas are neoplasms in soft tissues, often in the skin and subcutaneous tissue, and can also occur in internal organs, manifesting symptoms such as vomiting and abdominal distension. Stromal neoplasms, common in canine spleens, include fibrosarcomas and leiomyosarcomas. Surgery is the primary treatment, possibly combined with radiotherapy and chemotherapy. The surgical approach aims at the complete removal of the tumor, encompassing adjacent normal tissues. In this particular case, an 8-year-old Shar-Pei dog presented with abdominal distension and underwent various diagnostic tests, including bloodwork, biochemical tests (ALT, alkaline phosphatase, creatinine, and urea), ultrasonography, radiography, and electrocardiography. Ultrasonography revealed a significant-sized mass, approximately 10.89 x 15.21 cm, suggestive of a cavitary neoplasm. Exploratory laparotomy disclosed that the mass originated from the spleen and extended to the omentum. Total splenectomy was chosen, and biopsy samples were collected. Results indicated splenic stromal sarcoma, a specific type of tumor. This potentially fatal neoplasm necessitates early diagnosis through complementary exams. Surgery remains the treatment of choice, providing the patient with well-being and quality of life without complications.
