Definition

Gastrointestinal autonomic nerve tumor (GANT) is considered a variant of the phenotypic spectrum of GISTs (Miettinnen et al. 2010) displaying ultrastructural features of autonomic nervous system (enteric plexus) differentiation (Veloso et al. 2005) (e.g., neuritic processes, sparse synapses, and neurosecretory-type granules). Clinicopathological, histological, immunohistochemical, and molecular features of gastrointestinal autonomic nerve tumor indicate that they are similar to GIST (Lee et al. 2001). The small series of reported cases of this variant of GIST preclude validation of any specific implication regarding treatment, outcome, and management of patients with gastrointestinal autonomic nerve tumor diagnosis.
