[Urethral condyloma in the male: experience with 48 cases].
ABSTRACT To review our experience in the diagnosis and treatment of urethral condylomata.
From June, 1977 to November, 1994, 64 patients with condyloma acuminatum were treated at our institution. Forty-eight cases who had received no previous treatment were analyzed. The main reason for consultation was the appearance of an exophytic lesion in the meatus. Most of the condylomata were located in the navicular fossa. Treatment was by electrocoagulation in 24 patients, photocoagulation with the Nd:YAG laser in 21 and other treatment modalities were utilized in 3 patients. To determine the incidence of recurrence and response to therapy, we analyzed the data of 34 patients with a minimum follow up of 2 months and a mean of 16 months.
36% had associated cutaneous condylomata. Urethroscopy detected 14.2% of the lesions that were undetectable by eversion of the meatus. Recurrence was observed in 35.2%. There were no differences for recurrence or complications between patients submitted to electrocoagulation and those who were treated by laser photocoagulation.
Condyloma acuminatum of the urethra is uncommon. Urethroscopy is useful in making the diagnosis and for post-treatment follow up control evaluation. Electrocoagulation and Nd:YAG laser photocoagulation are useful in the treatment of this condition. Recurrence is frequently observed in patients with extensive lesions.

ABSTRACT: Scrotum's sebaceous cyst is an usual pathology, not life threatening, but susceptible of infection, producing abscess with their associated cosmetic and psychological disturbance. The classical management is the complete excision, under local anaesthesia, to prevent its recidive. Until today, the use of de Nd-YAG laser for the management of the scrotum's sebaceous cysts as not been reported. We report a case of a young man with several scrotum's sebaceous cysts, treated successfully with the use of a Nd-YAG laser.Actas urologicas españolas 03/2002; 26(2):121-3. · 1.14 Impact Factor

ABSTRACT: Electrocoagulation and laser evaporation for urethral condylomata acuminata have high recurrence rates and can be associated with urethral malformations. To investigate the effect of photodynamic therapy (PDT) with topical 5-aminolaevulinic acid (ALA) on urethral condylomata acuminata and to examine the histological changes in lesions of condylomata acuminata after ALA-PDT. Patients with urethral condylomata (n = 164) were given topical ALA followed by intraurethral PDT through a cylindrical fibre. Patients included 11 individuals with 16 penile or vulval condylomatous lesions which were biopsied before or after treatment; the histological changes were then evaluated by light microscopy and electron microscopy. The complete response rate was 95% and the recurrence rate was 5% after 6-24 months of follow-up. Light microscopy revealed keratinocytes in the middle and upper layers of the epidermis showing marked vacuolation and some necrocytosis 1 and 3 h after PDT. Necrosis in all layers of the epidermis was noted 5 h after PDT. Electron microscopy of keratinocytes revealed distinct ultrastructural abnormalities of mitochondria and the endoplasmic reticulum, and membrane damage. Apoptotic bodies were detected 3 h after PDT and a large number of keratinocytes exhibited necrosis 5 h after PDT. Results suggest that, compared with conventional therapies, topical ALA-PDT is a simple, effective, safe and well-tolerated treatment for urethral condylomata acuminata that is associated with a low recurrence rate. The mechanism might be the triggering of both apoptosis and necrosis by ALA-PDT in human papillomavirus-infected keratinocytes.British Journal of Dermatology 11/2004; 151(4):880-5. · 3.76 Impact Factor
