Vaginal fibrosarcomas are unusual mesenchymal tumours in cows... This report describes the clinical investigation, gross and histopathological findings, surgical treatment and postoperative course of a vaginal fibrosarcoma in a cow... They are usually pedunculated and can be removed surgically... Although they do not cause infertility, they may be associated with dystocia... Besides fibropapillomas, cases of squamous cell carcinoma, leiomyoma, fibroma, haemangioma, leiomyosarcoma and melanoma have also been reported in the vagina and vulva of cows... According to these histopathological findings, the tumour was diagnosed as a fibrosarcoma... In contrast to a fibropapilloma, the tumour did not consist of proliferating fibrous tissue with an epithelial covering of variable thickness... The cow was examined two weeks after the operation, and excellent wound healing was observed with no evidence of postoperative infection... A further examination was performed following a six-month period, no evidence of regrowth of any tumoral tissue could be found and the general condition of the cow was normal... This suggests that a favourable prognosis may be expected following proper extirpation of pedunculated tumoral masses in cows.

Figure 2: Fibrosarcoma with marked cellular pleomorphism and multinucleated giant cell. Haemotoxylin and Eosin. Original magnification × 480.

Mentions: Microscopically, the tumour was composed of spindle-shaped tumour cells forming interlacing bundles or arranged in herringbone patterns. The cells had marked cellular pleomorphism with oval or round and slightly hyperchromatic, nuclei with abundant eosinophilic cytoplasm. Mitotic figures were common and multinucleated giant cells were generally observed (Figure 2). The stroma of the tumour was made up of collagen fibres which were detected by van Gieson's and Masson's trichrome stains. According to these histopathological findings, the tumour was diagnosed as a fibrosarcoma. In contrast to a fibropapilloma, the tumour did not consist of proliferating fibrous tissue with an epithelial covering of variable thickness.
