Morphology and Micromorphological Examination of Giant Subcutaneous Fibrosarcoma in Goats: Five Cases

Veterinary literature states that subcutaneous fibrosarcoma may occasionally occur in the ear of a goat. Fibrosarcoma is characterized by spindle‐shaped fibroblast proliferation and collagen fiber synthesis. Fibrosarcoma should be considered when examining large, solid subcutaneous lumps in goat breeds, emphasizing the importance of gross and histological testing if there is limited facility availability in the lab for the correct diagnosis and therapy. The study started in January 2022 and will end in December 2024. During this period, only five goats were recorded, consisting of four from the Jamuna Pari breed and one from the Tota Puri breed. The study describes the five breeds and sexes of goats with left‐side ear giant tumors and the clinical, diagnostic, and pathological aspects of a large subcutaneous fibrosarcoma. All goats were subjected to physical exams and gross and histological tests for diagnosis. The animal had a huge, round, and elliptical mass in the subcutaneous tissue that was rapidly growing, firm, and nonencapsulated, with a varied pink–grey–yellow color upon dissection. Histological examination revealed densely packed spindle cells with interlacing bundles, cellular atypia, and mitotic activity consistent with fibrosarcoma. The infiltrative cancer precluded complete surgical resection. In this investigation, the ear tumor was removed completely. The present study suggests fibrosarcoma as a possible cause of enormous, solid tumors under the skin in several goat breeds, highlighting the necessity of histological evaluation for correct diagnosis and management. Early diagnosis and management increase the outcome and quality of life of animals during the entire surgical procedure.
