Papilloma
Definition:
(n.) A tumor formed by hypertrophy of the papillae of the skin or mucous membrane, as a corn or a wart.
Example Sentences:

(5) Quadrantectomy centered around the discharging duct, is the procedure of choice in this disease, at the interface between diagnostic and treatment, in fact, if benign tumors (papillomas) or non tumoral diseases (fibrocystic mastopathy and duct ectasia) predominate, invasive or in-situ malignant lesions represent 13 p. cent of these 46 discharges, justifying the significance of this clinical sign.
