Abstract
Objective: To describe the surgical approach performed in the treatment of basal squamous carcinoma attended at an institution in Amazonas, showing the effectiveness and applicability of the modified Tikhoff-Linberg technique. Case details: Male patient, 62 years old, with an ulcerated lesion on the left shoulder, diagnosed by biopsy with giant basoscamocarcinoma. He underwent shoulder amputation surgery with the modified Tikhoff-Linberg technique, with type III shoulder amputation - resection the clavicle and scapula, preservation of the humeral head, cervical and axillary lymphadenectomy, using deltopectoral dermofat flap to cover the open area. Thus, sixty days after surgery, the patient had intact hand movements and preserved arm flexion and extension. Surgical treatment ensured complete resection of the lesion, providing a good recovery with quality of life for the patient. Final considerations: No reports similar to the one presented were found in the literature. Therefore, this study significantly contributed to scientific research taking into account the rarity of this type of tumor, as well as the surgical technique selected for the treatment, benefiting professionals in the management of similar cases, in addition to additional benefits for patients.
