folliculoma

granulosa-theca cell tumor

 
an ovarian tumor predominantly composed of either granulosa cells (follicular cells) or theca cells, and often associated with excessive production of estrogen, with hyperplasia of the breast and endometrium and carcinoma of the endometrium. When luteinized, i.e., having cells resembling those of the corpus luteum, it is known as luteoma.

Results of the second biopsy confirmed the presence of a basal cell neoplasm consistent with feather folliculoma in both the left and right axillary lesions.
To our knowledge, these are the first reports of a folliculoma and basosquamous carcinoma in an anseriform species.
Feather folliculoma in a captive-bred barn owl (Tyro alba).
Skin biopsies were taken, and bilateral feather folliculomas were diagnosed on histopathologic examination.
Feather folliculomas are considered benign integumentary neoplasms and form sheets, cords, or nests.
Basal cell tumors, which have a similar gross and histopathologic appearance to feather folliculomas, were reported in a blue-fronted Amazon parrot (Amazona aestiva) and were bilateral.
Although feather folliculomas are generally considered benign, the large, ulcerative lesions could not be adequately treated in this case, and the bird was euthanatized.
