Abstract
We present the case of a 68-year-old patient with previous history of stage four malignant ulcerated nodular melanoma originated in the left pinna with pulmonary metastasis, who was admitted to the emergency department with an initial clinical suspicion of intestinal obstruction, confirmed by computed tomography. He underwent exploratory laparotomy, which revealed multiple small lesions in the small intestine suggestive of malignancy, causing distal jejunal intussusception conditioning the obstruction. The patient required resection of the affected bowel segment and subsequent intestinal anastomosis, with histopathological samples confirming melanoma metastases. The patient coursed with an adequate postoperative evolution and is now in a systemic oncology management plan. This case study reports an infrequent presentation of left pinna melanoma intestinal metastases presenting with small bowel obstruction and successful surgical management given to the patient in order to further broaden knowledge on this subject.
