Nevus sebaceous of Jadassohn is a congenital skin hamartoma often located on the face and scalp. A small percentage of these tumors evolve into malignant lesions, including basal cell carcinoma. We report a case of an elderly patient with nevus sebaceous since early childhood that evolved with a malignant transformation from the lesion to basal cell carcinoma. The treatment performed was surgical excision using Mohs surgery.

Patients with giant congenital melanocytic nevus are at higher risk of developing melanoma. After the first diagnosis of melanoma, there is also a higher incidence of subsequent melanomas in the same patient. However, the ideal therapy for this type of nevus is still controversial. We report the case of a patient with giant congenital nevus associated with multiple synchronous melanomas and the proposed treatment.

Surgical wounds, when not amenable to primary healing, can be treated using surgical flaps or grafts, increasing surgery complexity and costs. Seeking to facilitate and optimize access to surgical treatment of malignant neoplasms of the skin, the dressing using the Figueiredo technique is a good therapeutic option due to its easy execution and reproducibility, low cost, and effectiveness. We report a series of cases using this technique after the excision of non-melanoma skin tumors in the extremities.
