Introduction: Subcutaneous mycoses caused by dematiaceous fungi are classified according to their characteristics in the tissue: chromoblastomycosis (with the presence of fumagoid corpuscles), phaeohyphomycosis (with dematiaceous septate hyphae) and eumicetoma (with grains composed of septate hyphae). Several treatments are proposed, among them, surgical excision. Surgical treatment is more indicated in cases where there is localized infection and where excision is possible, yielding good therapeutic outcomes and low recurrence rates.
Objective: To describe the experience of a dermatological service in the surgical treatment of subcutaneous mycosis cases caused by dematiaceous fungi, discussing the surgical approach and its results.
Methods: A retrospective study was carried out with the descriptive analysis of cases treated from April 2014 to December 2016, at a dermatological clinic in the Brazilian Southeast city of São Paulo. All cases diagnosed with subcutaneous mycoses caused by dematiaceous fungi were included and surgically treated with total exeresis of the lesion.
Results: A total of 7 cases were analyzed – 2 eumicetomas, 1 chromoblastomycosis and 4 phaeohyphomycoses. Only one on the cases was not treated at an ambulatory surgical center. All cases progressed without sequelae or recurrences during the clinical follow-up.
Conclusions: When surgical treatment is possible, the exeresis of the lesion is a good therapeutic option in cases of subcutaneous mycoses caused by dematiaceous fungi.

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.

Introduction: In the Brazilian public health system, the current demand for dermatological procedures is greater than the offer, resulting in a waiting list of patients bearing dermatoses to be treated surgically. Aimed at reducing that waiting list, a collective effort of surgical procedures was carried out in the tertiary public health service. The corresponding data on the patients and lesions is disclosed in the present study. Objective: To assess the profile of the patients – and respective skin lesions – who are awaiting to undergo dermatological procedures. Methods: A simple descriptive profile analysis of the patients, treated dermatoses and procedures performed was carried out. Results: Thirty-one patients (aged between 21 and 95 years, mean = 63.7 years). Seventeen (54.83%) were women and 14 (45.17%) were men. Thirty-eight lesions were treated: 21 neoplastic (carcinomas and melanomas), 8 pre-neoplastic (actinic keratoses) and 9 non-neoplastic (nevi, keloid and neurofibroma). Conclusions: The present article is relevant due to the fact it identifies cases and patients awaiting dermatological surgical procedures in the public health system. Based on it, a better planning of public health strategies in the dermatological field should be possible. Also, it highlights the importance of the dermatologist physician’s action in the public health, diagnosing and treating pre-neoplastic and neoplastic lesions.

The dermatologist's clinical practice is based on the analysis of cutaneous lesions that is carried out mainly by clinical observation, and currently supplemented with tests such as dermoscopy and confocal microscopy. Despite its low cost, the Wood's lamp has been decreasingly used as an auxiliary diagnostic method. The authors of the present study describe several cases of use of the Wood's lamp where it provided valuable assistance to the dermatologist, aiming at encouraging the use of this device in the daily practice.

INTRODUCTION: Extramammary Paget disease consists of a cutaneous adenocarcinoma in areas of apocrine glands. It is a rare neoplasia, and its surgical treatment yields satisfactory results. However, due to the high recurrence rates, surgeries are potentially disfiguring. Imiquimod is a topical immune-stimulant used for the treatment of anogenital warts and in situ carcinomas. Its use has been described in the scientific literature for the treatment of Extramammary Paget disease with satisfactory results.
OBJECTIVE: Describe the course of four cases of Extramammary Paget disease treated with imiquimod, to evaluate evolution and therapeutic response.
METHODS: A retrospective study was performed in a service of dermatology in the city of São Paulo, with the review of medical records of all patients diagnosed with Extramammary Paget disease and treated with imiquimod from January 2011 to July 2018.
RESULTS: Four patients were included, three with vulvar lesion and one with scrotal lesion. Two women presented completed resolution of the disease, one did not respond and the man progressed with 70% regression of the lesion, having undergone surgical excision of a considerably smaller area than the initial lesion.
CONCLUSIONS: Imiquimod presents as a valid therapeutic modality for the treatment of Extramammary Paget disease.

Scabies is a contagious cutaneous infection, caused by burrowing of the mite Sarcoptes scabiei var. hominis in the epidermis. The clinical suspicion is due to the history, clinical distribution of lesions and its aspect; however, the confirmation is with the detection of the parasite. We present the features of the diagnostic methods for scabies, from its detection through direct microscopy of skin scrapings from a lesion or with the use of an adhesive tape on the lesions, to its detection using the dermatoscope, a tool available in most dermatology clinics, which, even in unexperienced hands, has acceptable sensitivity and specificity.

Warts are the most frequent periungual tumors presented in dermatological consultations. They are caused by several types of human papillomavirus (HPV), and some of these lesions evolve to a spontaneous cure. However, there are lesions that do not regress without a therapeutic approach, and some of them are resistant to several therapies. I present a case of a 14-year-old patient with disseminated periungual warts in both hands, resistant to several previous therapies, and who evolved with cure after the use of occlusive imiquimod.

Dowling-Degos disease (DDD) is a rare genodermatosis. Progressive reticular hyperpigmentation of flexural areas mainly characterizes the disease, which may be associated with a large spectrum of benign lesions and cutaneous neoplasms. It may cause psychosocial impairment due to the deformity caused by the lesions with significant aesthetic damage. We present two cases of male patients with hyperchromic macules, multiple comedones, epidermal cysts, cribriform scars on the face, cervical region, dorsum, anterior thorax, armpits, genital region, and disfiguring tumors, characteristic of DDD.

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.
