RESUMEN

Immune checkpoint inhibitors have emerged as a promising cancer treatment, allowing significant and long-term therapeutic responses. Nivolumab, an anti-programmed cell death protein-1, is one of the molecules of this therapeutic class with known and manageable side effects. Giant cell arteritis is a rare immune-related adverse event most often manifested by headaches poorly released by common antalgics and can result in visual loss. We report its occurrence in an 80-year-old patient on maintenance nivolumab for metastatic clear cell renal carcinoma. Prompt diagnosis and initiation of glucocorticoid therapy led to symptom improvement and visual recovery.

RESUMEN

INTRODUCTION AND IMPORTANCE: Adenocarcinoma of the jejunum is a diagnostic challenge for the physician because of its extreme rareness and the fact that it classically presents with vague clinical symptoms. On the other hand, the Sister Mary Joseph's nodule is a rare clinical sign that refers to umbilical metastasis of an internal malignancy. We here report a rare case of jejunal adenocarcinoma revealed by a Sister Mary Joseph's nodule. CASE PRESENTATION: A 55-year-old man presented with an ulcerated umbilical tumor, which was found to be a secondary lesion of an advanced jejunal adenocarcinoma invading the transverse colon. He underwent surgical resection of the umbilical tumor and the intestinal primitive. CLINICAL DISCUSSION: The presence of umbilical metastasis usually represents advanced disease but can be its first manifestation. Gastro-intestinal tract tumors such as jejunal adenocarcinomas and gynecologic malignancies are the most common primary sites. CONCLUSION: Practicians must be aware of clinical implication of Sister Mary Joseph nodule. Aggressive surgery when feasible can be beneficial for survival.
