Melanoma is the most rapidly increasing cancer in the world. Associated morbidity and mortality are mainly related to metastatic potential. Metastases to the breast from malignant melanoma are rare and represent only 1.3%–2.7% of reported cases. The aim of this study was to present a rare case of metastatic malignant melanoma to the breast. A 51-year-old woman was admitted for management of a palpable mass of the left breast. The past medical history referred to a sizable nodular melanoma that was removed from her back. Classification of the breast lesion was BI-RADS 5. Core needle biopsy was compatible with the diagnosis of malignant melanoma. Immunohistochemical evaluation was positive for Mart1 and Ki67. Subsequent staging was indicative of multiple secondary foci in the liver and bones. The patient was administered a combination of PD L1 inhibitor nivolumab with the anti-CTLA4 inhibitor ipilimumab followed by additional targeted therapy with the BRAF inhibitor vemurafenib. Metastasis to the breast from malignant melanoma is extremely rare. Nevertheless, breast metastases must be suspected in patients with a history of malignant melanoma. Moreover, recent breakthroughs in the Braf and MEK inhibitors and immune checkpoint inhibition therapies have impressively improved prognosis in patients affected by melanoma.

BACKGROUNDIntraabdominal adhesions develop spontaneously or after an inflammatory process or surgical procedure in the abdomen. They are the most common cause of small bowel obstruction (SBO). SBO occasionally leads to intestinal ischemia (InIs) which can be a life-threatening condition that requires management as soon as possible. We herein report a case of SBO with InIs presented in our institution and treated without intestinal resection.CASE SUMMARYA 34-year-old man presented at the emergency department after a 12-h-onset diffuse abdominal pain, bloating and nausea. He had a history of traumatic right hepatectomy 11 years ago as well as adhesiolysis and resection of a long part of small bowel 2 years ago. An abdominal computed tomography (CT) showed dilated loops that led to the diagnosis of SBO. Due to deteriorating lactic acidosis, the patient was operated. Torsion of the small bowel around an adhesion led to 2.30 m of ischemic ileum. After the application of N/S 40 °C for 20 min, the intestine showed signs of improvement and it was decided to avoid resection and instead temporary close the abdomen with vacuum-pack technique. At the second-look laparotomy 48 h later, the intestine appeared normal. The patient was discharged on the 8th post-op day in excellent condition.CONCLUSIONIn case of SBO caused by adhesions, extreme caution is needed if InIs is present, as the clinical signs are mild and you should rely for diagnosis in CT findings and lactate levels. Conservative surgical approach could reverse the effects of InIs, if performed quickly, so that intestinal resection is avoided and should be used even when minimum signs of viability are present.
