Congenital granular cell tumor with uncommon clinical behavior.

Abstract

Congenital granular cell tumor (CGCT), also known as congenital epulis, is a rare benign mesenchymal tumor of the oral cavity. We report of a 3 years and 7 months old female patient undergoing surgical excision of an oral tumor. Subsequent histological and immunohistological investigations within the clinical course led to the diagnosis of CGCT. However, clinical findings in this case, such as primary onset and an untypical location within the oral cavity, clearly stand in contrast to those usually found in CGCT, resulting in an exceptional case not previously described in the literature.
