Abstract: | Type I gastric carcinoids are indolent lesions that only rarely metastasize. Until now, lymph node metastasis had only being observed in large (>= 10 mm) and usually invasive lesions (deep submucosa or beyond). This study reports a diminutive (8 mm) gastric carcinoid, limited to the superficial layer of the submucosa (sm1), with no angiovascular invasion, but with a high Ki-67 index (7%) and an involved perigastric lymph node. The aggressive behavior of this lesion ends the previous believe that small and superficial type I gastric carcinoids do not metastasize. This case also indicates that better parameters are necessary to evaluate the malignant potential of these lesions and presents a further support to the value of 2010 World Health Organization classification of gastrointestinal neuroendocrine tumors. |
