DermDx: Growth on Testes

A 61-year-old man with a history of atrioventricular block and perforated ulcer was referred for evaluation of enlarging growths on his testicle. These growths were first noted approximately 6 months ago and are itchy at times. The patient denies any bleeding or pain related to the growths.  Physical examination reveals a 3-cm firm, nonulcerated, multilobular tumor with variegate coloration.

Buschke-Löwenstein tumor (BLT) is a type of verrucous carcinoma first described by Buschke and Löwenstein in 1925.1 It is caused by the human papillomavirus (HPV), in particular by HPV serotypes 6 and 11, and is always preceded by condyloma acuminata.2...

Buschke-Löwenstein tumor (BLT) is a type of verrucous carcinoma first described by Buschke and Löwenstein in 1925.1 It is caused by the human papillomavirus (HPV), in particular by HPV serotypes 6 and 11, and is always preceded by condyloma acuminata.2

The carcinoma is rare, with an incidence among sexually active adults of approximately 0.1% per year.2 It can occur at any age after puberty but mainly is seen among adults aged 40 and 60 years.2 Although HPV infection affects both men and women, the incidence in men predominates.Immunosuppression, chronic inflammation, poor hygiene, and coinfection with HIV are likely to be risk factors for the development of BLT.2

BLT is a variant of squamous cell carcinoma (SCC) that most commonly appears on the glans penis, foreskin, or perianal regions.1 It typically begins as a small keratotic papule that over several years morphs into a cauliflower-like mass with cutaneous fistulas and a cobblestone surface. 1 The size of the growth may exceed 10 cm.3

Histopathologically, BLT exhibits a densely keratinized and well-differentiated epithelium. Structures similar to those seen in condyloma acuminata are noted such as vacuolization of the cells in the superficial layer of the epidermis, marked degree of acanthosis and parakeratosis, and infrequent mitotic figures.3 BLT is differentiated from other growths by its thicker stratum corneum, marked papillary proliferations, and its tendency to invade deeply, displacing the underlying tissues.4 Differentiation between BLT and malignant SCC is based on the absence of invasion, intact basement membrane, infrequent mitotic figures, and no development of metastases. Since the description of this entity, there have been numerous reports of SCC coexisting with the BLT.4 

Mohs surgery is a preferred treatment modality as it allows for tissue sparing while enabling the surgeon to ensure tumor-free margins and recognize foci of SCC.5 If necessary, surgical defects can later be surgically reconstructed. 6 BLT has a high rate of recurrence.5 In most cases, BLT recurrences are managed by radical surgery or carbon dioxide/argon laser resection.7

Topical, intralesional, and oral chemotherapy have been used as adjuvant therapy and for treating tumor recurrences after surgery.8,9 Chemotherapy alone, however, has not shown promising results.10 Radiation therapy, in spite of its neoadjuvant application in a limited number of BLT cases, has largely been avoided, mostly because of the fear of causing further malignant transformations.11,12
