Splenic metastasis from neuroendocrine tumor of the stomach: A case report

Splenic metastasis is extremely rare, and neuroendocrine tumor of the stomach represents one of the rarest primary sources. The present study aimed to describe a rare case of an endocrine tumor of the stomach revealed by a splenic metastasis. We report a rare case of a 40 -year-old who presented a pain in her left hypochondriac, associated to sensation of heaviness. Abdominal ultrasound showed splenomegaly with a large lobulated hyperechoic mass associated to splenic vein thrombosis. A magnetic resonance imaging (MRI) confirming the splenomegaly, containing a large lobulated and heterogeneous mass occupying the almost totality of this organ and invading the venous system. The histological study of this splenic mass demonstrated to secondary splenic location of a grade 1 neuroendocrine tumor. As part of an investigation for a primary tumor, fibro scopy was performed and revealed an ulcerating-bourging fundic process with a histological study in favor of a grade 1 neuroendocrine tumor.
