摘要

Ovarian tumors in marine teleosts are exceptionally rare, with few documented cases in the literature. This study reports a spontaneous ovarian tumor in an adult Indian oil sardine, Sardinella longiceps Valenciennes, 1847, collected from the coastal waters off Parangipettai, Southeast coast of India. Gross pathological examination revealed a solitary, pale reddish, fleshy mass confined to the right ovary, with no metastatic lesions observed in other visceral organs. Histopathological evaluation showed interlacing bundles of spindle-shaped to elongated cells with centrally located, cigar-shaped nuclei. Histochemical staining revealed strong positivity for Masson’s trichrome, periodic acid–Schiff (PAS), Van Gieson, and argyrophilic nucleolar organizer regions (AgNOR), consistent with smooth muscle origin. Based on these findings, the tumor was diagnosed as a leiomyoma. To our knowledge, this represents the first confirmed report of ovarian leiomyoma in S. longiceps, contributing valuable insight into reproductive pathology in marine fish.
