Papillomas of the conjunctival surface in people can be of viral or nonviral origin and are found in high association with human papillomavirus. Canine conjunctival papillomas are seldom described, and published accounts have mostly been associated with canine oral papillomavirus infection. Here, we describe conjunctival squamous papillomas that do not express papillomavirus proteins and compar...

PURPOSE Demonstrate radiological findings of 127 angiomyolipomas (AMLs) and propose a classification based on the radiological evidence of fat. MATERIALS AND METHODS The imaging findings of 85 consecutive patients with AMLs: isolated (n = 73), multiple without tuberous sclerosis (TS) (n = 4) and multiple with TS (n = 8), were retrospectively reviewed. Eighteen AMLs (14%) presented with hemorr...

BACKGROUND Sinonasal papillomas are benign epithelial neoplasms arising from Schneiderian mucosa. The three subtypes, exophytic, oncocytic, and inverted (inverted papilloma [IP]), should be distinguished from one another histopathologically. This study (1) highlights the histopathological and clinical differences between the Schneiderian papilloma subtypes and (2) identifies clinical features t...

Background: Benign and high-risk breast lesions can be excised when symptomatic or for diagnotisc purposes. Although vacuum assisted excision (VAE) is a safe effective alternative to surgical excision(SE), most hospitals still use SE the management of benign high risk lesions. To evaluate health care benefit VAE, hospital costs cosmetic outcome after VAE were compared SE. Additionally, periods ...

BACKGROUND Verruciform xanthoma is a benign verrucous lesion characterized by epithelial acanthosis and lipid-laden foamy histiocytes in the connective tissue papillae. It typically presents as a papillomatous, polypoid, or sessile lesion. Verruciform xanthoma is most commonly observed within the oral cavity. However, albeit less frequently, it develops on the penis, scrotum, or vulva. PURPOS...
