title: [Granular cell tumour of the parotid gland. The differential diagnostic criteria (author's transl)].
abstract: Granular cell tumours (synonyms: myoblastmyomas, granular neuromas, granular cell myoblastomas) are localized predominantly in the head and neck area, especially in the region of tongue and larynx. Only 2 observations of an occurrence in the parotid gland exist till now in the world literature. This paper reports a further case of an occurrence in the parotid gland in a 6-years-old girl. The about cherrygreat tumour was distinctly limited and showed histologically a typic lobular arrangement of acidophilic granular cells. No recidive was observed in the prevailing postoperative phase of 3 years. The differential diagnosis of the granular cell tumorus is demonstrated to other tumour types with similar histological arrangement, expecially to the alveolar soft-part sarcoma, the acinic cell tumour and the non-chrom-affine paraganglioma (chemodectoma).
