Primary Melanoma of the Small Intestine with a Metastatic Lymph Mass in the Inguinal Canal: A Case Report

Objectives: We report a case of primary melanoma of the small intestine. Primary intestinal melanoma (PIM) is an extremely rare neoplasm for which the cause is unknown. Materials and methods: A 67-year-old man was admitted to our department due to abdominal pain, constipation, a large, hard inguinal mass and severe anaemia. Results: After laboratory data, imaging techniques and histopathological examination, the diagnosis was confirmed. A surgical resection of the intestinal neoplasm, treatment with BRAF inhibitors and radiation therapy to the inguinal mass were performed. Conclusion: PIM is rare and it is usually difficult to establish its exact origin

Síndrome constitucional incompleto secundario a enfermedad de Crohn yeyunal aislada

A 36-year-old Senegalese woman with incomplete constitutional syndrome, slightly more than one year of evolution, with presence of bowel pains, vomits, diarrhea and iron deficiency anemia. Early diagnosis studies about parasite, digestive (including celiac disease), endocrine-metabolic, gynecologic and tumor diseases are conducted, with negative results. During the evolution the patient is histopathologically diagnosed with duodenosis lymphocytic, presenting a vast array of possibilities. By exclusion, we centered our suspicions on a disease located in the small intestine, using (capsule) endoscopy. This shows jejunal erosive injuries and annular stenosis. These clinical findings suggest a diagnosis of inflammatory bowel disease, starting the treatment with prednisone, with a good response.Mujer senegalesa de 36 años con síndrome constitucional incompleto de algo más de un año de evolución acompañado de molestias abdominales, vómitos, diarrea y anemia ferropénica. Se realiza estudio de cribado de enfermedades parasitarias, digestivas (incluyendo la celiaquía), endocrinometabólicas, ginecológicas y tumorales siendo los resultados negativos. Durante su evolución se diagnostica histopatológicamente de duodenosis linfocitaria planteándose amplio abanico de posibilidades. Por exclusión, centramos nuestra sospecha en una enfermedad localizada en intestino delgado gestionándose capsuloendoscopia que mostró lesiones erosivas yeyunales y estenosis anulares. Los sugerentes hallazgos orientan al diagnóstico de enfermedad inflamatoria intestinal, comenzando tratamiento con prednisona con buena respuesta
