  • Title: [Buschke-Lowenstein penile tumor].
    Author: Buffet M, Aynaud O, Piron D, Dupin N, Escande JP.
    Journal: Prog Urol; 2002 Apr; 12(2):332-6. PubMed ID: 12108356.
    Abstract:
    The Buschke-Löwenstein genital tumour is a poorly defined, uncommon tumour. The distinction between benign lesions, potentially malignant lesions and carcinomatous lesions is difficult. The authors report a case of Human Papillomavirus (HPV) 11-associated Buschke-Löwenstein tumour with an area of micro-invasive carcinoma on histological examination of the surgical resection specimen. A 34-year-old patient was operated for recurrent condylomatous lesions of the penis with scrotal extension. Histological examination of the complete operative specimen confirmed the presence of Buschke-Löwenstein tumour as well as an area of dermal micro-invasion on one section. Molecular hybridization revealed the presence of HPV 11 DNA and immunohistochemistry showed basal cells weakly expressing mutant p53. The classification of Buschke-Löwenstein tumours is controversial. Some authors consider these tumours to be benign tumours or giant condylomata (non-metastatic, associated with HPV 6-11), while others consider these tumours to be borderline malignant (local extension and risk of progression to invasive carcinoma). The role of HPV as cofactor involved in carcinomatous transformation also remains controversial. The authors emphasize the need for surgical resection of this type of tumour with histological examination of the entire operative specimen looking for areas of micro-invasion. In the presence of micro-invasion with healthy resection margins and staging by clinical examination and complementary investigations, treatment essentially consists of regular surveillance.
