Introduction: The occurrence of anogenital warts in children is relatively rare, however it generates distress for the family and the physician regarding the possible association with sexual abuse.
Objective: To demonstrate cases of anogenital wart in children and the therapeutic options used.
Methods: Retrospective descriptive study of anogenital warts in children under 12 years of age, with a mean age of 4 years, treated between 2011 and 2015, in a sexually transmitted diseases public outpatient clinic in the Brazilian Southeast city of São Paulo.
Results: The authors demonstrated 20 cases — of which 12 were female and 8 were male. The preferred location for the lesions was the perianal region (70%), with 30% of the children presenting extragenital warts. The treatment of choice in 65% of cases was the application of topical medication (podophyllin and imiquimod). The longest time to cure was 20 weeks.
Conclusions: Anogenital condyloma was more frequent in girls, the mean age was 4 years, and the most affected site was the perianal region. The lesions had good therapeutic response with the application of the topical treatment of choice.

Buschke-Lowenstein tumor (BLT) is an extremely rare variant of condylomata acuminata that presents a benign biological behavior and histological characteristics despite being clinically presented by large lesions. Many therapeutic approaches are available, many of which rely on extensive and mutilating surgical procedures. We present two cases of patients with BLT treated with topical podophyllin whose therapeutic responses were extremely favorable in both cases.

Genital infection by Human Papillomavirus occurs 65% of the time after contact with contaminated skin and mucosa. Most people eliminate the virus through the immune system. Individual factors such as smoking, age, multiparity, prolonged use of hormonal contraceptives, sexual behavior, and infection by other Sexually Transmitted Diseases cause viral perpetuation and genital lesions, most of them asymptomatic. The most affected regions are anogenital. Treatment should be individualized. Excessive treatment can lead to scarring. We report a case of multiple treatments for removal of genital condyloma with consequent formation of extensive vulvar keloid.

DNA-virus, which belongs to the papillomavirus group, causes Condylomata acuminata. In children under 3 years of age, transmission tends not to be due to sexual abuse but rather vertically. There is no consensus for the treatment of anogenital warts in children. The chosen method is individualized for each patient, preferring less traumatic treatments, with fewer sequelae. Although there are still some restrictions on the imiquimod use in children under 12, studies have already shown this therapy’s success in this age group. We report a case treated with 5% imiquimod cream with the resolution of pre-existing lesions.

BACKGROUND: Anogenital warts are the most prevalent sexually transmitted infection (0.5%) among dermatological consultations. Cryotherapy with liquid nitrogen (LN) and therapy with trichloroacetic acid (TCA) are remarkable among the treatment strategies.
OBJECTIVE: To evaluate the effectiveness of LN versus TCA in to treat penile warts in patients from a Brazilian public institution.
METHODS: Open, parallel, randomized clinical trial. Following randomization, the warts were counted and submitted to cryotherapy (10s) or case therapy (TCA 80%) in each visit. The primary dependent variable was the lesion count before and after four weeks of treatment. We assessed the following variables: complete clearance, age, immunosuppression, smoking, topography, and education.
RESULTS: 142 treatments were evaluated in 52 participants. There was a predominance of young adults, and the main topography affected was the penis shaft. The mean reduction rate per session was 48% for LN and 26% for TCA (p=0.11). 42 (81%) participants achieved complete clearance, with 39 (75%; 95% CI: 64-85%) reaching clearance in up to three sessions. Age was associated with a worse therapeutic response rate (ß =-0.09; p<0.01).
CONCLUSIONS: LN and TCA proved to be effective to treat penile warts, without difference between treatments. Age was associated with a worse therapeutic response.

Pilomatricoma is a benign skin tumor derived from the hair follicle. It has a varied etiology, and the traumatic one is often described as a triggering factor. The surgical treatment is curative and, therefore, the choice. We report a case of an atypical clinical presentation pilomatricoma – an ulcerated nodule topped by a central hematic crust, with peripheral telangiectasias probably triggered by the HPV vaccination. The ultrasound examination suggested the possibility of a chronic inflammatory granuloma, although the histopathological examination was definitive and confirmed the diagnosis of pilomatricoma.

INTRODUCTION: Many options for anogenital warts (AGWs) treatment are available. Recently, trichloroacetic acid (TAA) and liquid nitrogen (LN) began to be associated to treat AGWs.
METHODS: Randomized, parallel, controlled clinical trial involving patients with penile AGWs. Patients were treated with LN, TAA, or their combination and reevaluated after 28 days.
RESULTS: Among therapy with TAA, LN, and their combination, the clearance rate was 22.9% (95% CI: 8.6%-34.3%), 46.2% (95% CI: 30.8%-59.0%), and 25.7% (95% CI: 11.4%-37.2%), respectively.
DISCUSSION: All therapeutic options were effective. Though, there was no statistically significant difference between the groups.
