Primary Small Bowel Melanoma or Small Bowel Metastasis with Vanishing Primary Cutaneous Lesion

引用

Case Reports in Clinical Medicine 2022年第3期11卷 63-71页

作者： dana Criṣan Andreea Ardelean Mihaela Coman laurenţiu Stoicescu Ioana Rusu Nadim Al Hajjar Tudor Pop Sorin Criṣ an Constantin Bodolea Lucreţ ia Avram Faculty of Medicine Iuliu Hatieganu University of Medicine and Pharmacy Cluj-Napoca Romania Clinical Municipal Hospital Cluj-Napoca Romania 3rd Medical Clinic “Octavian Fodor” Regional Institute of Gastroenterology and Hepatology Cluj Cluj-Napoca Romania

The small bowel represents one of the main sites for cutaneous melanoma metastasis;however, numerous cases of primary intestinal melanoma have recently been described. In view of this, we present the case of a 39-year-old woman admitted for nausea, heartburn, abdominal pain, change in bowel habits and weight loss. Contrast-enhanced CT revealed a small bowel mass. Surgical resection of a 6 cm ileal tumour with regional mesenteric lymphadenectomy and end-to-end anastomosis was performed. Histopathological findings indicated the presence of an ileal melanoma metastasis. Subsequent dermatological examination identified a cutaneous lesion on the right forearm, however no malignant cells were found at the histopathological exam. Whole body PET CT with FDG identified multiple frontal and parietal lesions. Genetic testing was positive for BRAF gene V600 E mutation. The patient underwent multiple neurosurgical procedures for the resection of cerebral metastases. Palliative external radiation and chemotherapy was also attempted. After approximately 2 years after the diagnosis, the patient died following multiple episodes of intracranial hypertension.
