title: Adenomyofibroma of the fimbria in a cynomolgus monkey (Macaca fascicularis).
abstract: A 20-year-old female cynomolgus monkey (Macaca fascicularis) was presented for an end-of-study necropsy. At necropsy, a 2 cm x 1.5 cm x 1 cm, butterfly-shaped, multilobulated mass extended off the right uterine tube fimbria. Microscopically, the mass was composed of large, plump, finger-like projections lined primarily by simple columnar ciliated epithelium. The interstitium contained a proliferation of smooth muscle stromal cells admixed with varying amounts of collagen. A diagnosis of adenomyofibroma of the fimbria was made. This benign neoplasm should be considered as a differential diagnosis for masses arising from the fallopian tube in old-world macaques.
