Intraductal papillomas of the breast are benign lesions with an incidence of approximately 2-3% in humans. [1] They result from abnormal proliferation of the epithelial cells lining the breast ducts. [2] Two types of intraductal papillomas are generally distinguished. The central type develops near the nipple.
Intraductal papillary mucinous neoplasm (IPMN) is a type of tumor that can occur within the cells of the pancreatic duct. IPMN tumors produce mucus, [1] and this mucus can form pancreatic cysts. [2] Although intraductal papillary mucinous neoplasms are benign tumors, they can progress to pancreatic cancer. [1]

A papilloma (plural papillomas or papillomata) (papillo-+ -oma) is a benign epithelial tumor [1] growing exophytically (outwardly projecting) in nipple-like and often finger-like fronds. In this context, papilla refers to the projection created by the tumor, not a tumor on an already existing papilla (such as the nipple).
The diagnosis of PB may be suggested in individuals with the clinical presentation of PB plus the presence of a family history of mammary secretory carcinomas, lobular carcinoma, ductal carcinoma in situ, invasive ductal carcinomas of no special type, [4] [5] [14] Cowden disease, Noonan syndrome, Proteus syndrome, or neurofibromatosis type 1.
Florid cutaneous papillomatosis (FCP) is an obligate paraneoplastic syndrome. FCP begins as the sudden onset of numerous cutaneous papillomas that are clinically indistinguishable from viral warts. The papillomas range from 1 to 3 mm in diameter may spread to involve the entire body, including the face.
Papillary renal cell carcinoma (PRCC) is a malignant, heterogeneous tumor originating from renal tubular epithelial cells of the kidney, which comprises approximately 10-15% of all kidney neoplasms. [1] Based on its morphological features, PRCC can be classified into two main subtypes, which are type 1 and type 2 (eosinophilic). [2]
