Pathological characteristics of normal and cancerous chicken ovaries. Follicles are hierarchically arranged by stage of development (F1-F5) in the normal ovary (A). The cancerous ovary has surface tumor lesions and atretic follicles (B). Hematoxylin and eosin staining of normal (C) and cancerous (D) ovaries from hens. F, follicle; S, stroma; NA, nodule area.
