Introdução: Skin tumors are common and may present irregular growth, requiring resections with diverse geometric shapes. Many descriptions have been reported. Objective: To describe a triangle-shaped excision technique followed by primary closure in the treatment of skin cancer. Methods: Patients (n = 11) with tumors of between 1.8 and 5.7 cm located in areas that favored the use of equilateral triangle-shaped incision and primary closure were studied. Results: All patients had their surgical closure in the shape of a “Y.”Two cases of partial dehiscence of the suture were observed in the post-operative period. Conclusions: The surgical technique of primary closure of triangular excisions of skin allows effective control of the surgical margins and leads to good cosmetic results, preserving the surrounding tissue.

Confluent and reticulated papillomatosis of Gougerot and Carteaud is a disease of uncertain etiology, the main differential diagnosis being pityriasis versicolor. The authors describe two cases of the disease - one in a man and one in a woman - both with good therapeutic response without recurrence after use of minocycline.

Primary cutaneous nodular amyloidosis is a rare form of amyloidosis. The authors report the case of a 44-year old woman with nodules and plaques on the legs with three years of development and increase in the number and size of lesions. Clinical, histological and laboratory investigation dismissed the possibility of systemic amyloidosis, and the diagnosis of nodular amyloidosis was established. A decision was made for the surgical approach, using curettage and cauterization with good response to the proposed treatment.
