Case Reports[Intestinal relapse of a cutaneous melanoma. Report of one case].
Digestive tract primary melanoma is uncommon. However, metastatic lesions are more frequent and occur mainly in the small intestine. We report a 69-year-old male patient who consulted for a hyperpigmented skin lesion on the left thigh associated with multiple subcutaneous nodules. ⋯ Laparoscopic resection with primary anastomosis was performed with good clinical evolution. The definitive biopsy showed a melanoma metastasis with two of three lymph nodes positive for metastasis and a non-mutated BRAF gene. In conclusion, a single intestinal recurrence of melanoma is rare and requires an active search, since it can be resected using minimally invasive techniques.

Cervicocranial arterial dissection (CIAD) is an important cause of stroke. ⋯ Due to the greater availability of non-invasive imaging methods, 50% of these patients with CIAD did not have a stroke. Thus, an earlier and more timely management is feasible.
