title: [Granular cell tumors of the colon. Clinical case and review of the literature].
abstract: Abrikossoff's tumours are better known as granular cell tumours because of the typical microscopic aspect of their cytoplasm. They are uncommon neoplasms, probably of neurogenic origin, typically subepithelial and often benign. Rarely, they may be localised in the digestive tract, where they are mostly asymptomatic and tend to be discovered incidentally during endoscopic examinations indicated for other diseases. Histological examination with immunohistochemical staining usually yields the definitive diagnosis. Most authors agree as to the indication for endoscopic resection because of the possible, though rare, aggressive biological behaviour of these tumours. In the present paper we report on a case of granular cell tumour of the caecum, endoscopically resected and staining positively at the immunohistochemical search for the S100 protein.
