INTRODUCTION: Ingrown toenail is the leading cause of nail surgery. Techniques have been described for better exposure of the nail matrix in Grade III treatment, such as block excision of the hypertrophic skin margins and the subcutaneous nail blade involved, removing a semi-elliptic wedge and or L-incision, both advocating closure by suturing the skin and the nail blade. Authors describe the application of an incision technique at the intersection of the lateral and proximal nail fold to expose the matrix and the performing of a wedge in the cutaneous hypertrophy. At the site of the nail blade removal a fragment is left by second intention.
OBJECTIVE: To assess the comfort and effectiveness of the new surgical technique for onychocryptosis.
METHODS: Observational and retrospective study through the analysis of 29 patients with onychocryptosis who underwent the new technique.
RESULTS: Of the 34 nail folds (5 patients had 2 affected nail folds) submitted to surgery using the new technique, only one patient had recurrence in one of the folds and underwent a new intervention. No complaints of postoperative discomfort or complications were observed.
CONCLUSIONS: The applied technique was satisfactory, with a low recurrence rate, and also easy to perform, presenting no discomfort complaints from patients.

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.

Sarcomas são neoplasias mesenquimais malignas, raras, que acometem, principalmente, crianças e adolescentes. O rabdomiossarcoma, subtipo oriundo da musculatura esquelética, é condição incomum em adultos, acometendo sítios de localização não habitual, crescimento rápido e de difícil tratamento. Apresenta-se caso de adulto jovem com nodulação em lóbulo auricular esquerdo, cuja análise histopatológica e imuno-histoquímica confirmou tratar-se de rabdomiossarcoma alveolar, o qual foi conduzido em conjunto com a Oncologia.

Acral amelanotic melanoma is rare and can mimic many entities, such as eccrine poroma, squamous cell carcinoma, plantar wart, and chronic ulcers. Due to the variety of possible differential diagnoses, it is a challenging and frequently late diagnosis. Dermoscopy features can help in early diagnosis. The dermatologist should keep this diagnosis in mind when faced with a pink, progressively growing, irregularly shaped lesion, mainly if located on the hands and feet.

Aneurysmal dermatofibroma (ADF) is a rare benign tumor originating in the dermis. It is most common in the lower limbs of women over 30 years. Its etiology is unknown, and histopathological examination confirms the diagnosis. This paper presents a case of ADF with an exuberant presentation in a young female patient with a pedunculated tumor in the right pretibial region, measuring 12 cm in greatest diameter. This report aims to demonstrate an infrequent variant of dermatofibroma with significant growth and emphasize the importance of lesion excision and follow-up because of the high recurrence rate.

Merkel cell carcinoma is a rare and aggressive cutaneous neuroendocrine cancer that occurs in the photodamaged skin of white and elderly patients, usually presenting as a solitary plaque or nodule in the head and neck region. When located in the lower palpebral area, reconstructing the defect resulting from its excision can become challenging for the dermatological surgeon due to the local cosmetic and functional peculiarity. We report the use of a bilobed flap for lower eyelid reconstruction with a satisfactory result, both in terms of aesthetics and the resulting functionality.

O fibroxantoma atípico (FXA) é um tumor mesenquimal raro que geralmente acomete pacientes com idade avançada, do sexo masculino, em áreas fotoexpostas. É mais frequente na cabeça e pescoço, mas também pode ocorrer no tronco e nas extremidades. Atualmente, é considerado um tumor benigno de diagnóstico por exclusão, com baixa taxa de recidiva e metástase. O tratamento é realizado com excisão cirúrgica, o que permite o diagnóstico por avaliação histológica e imuno-histoquímica.
