An Unusual Granular Cell Tumour of the Buttock and a Review

License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. Granular cell tumours, first described by Abrikossoff in 1926, are known to occur in skin, connective tissue, breast, gastrointestinal and genital tracts.While they are rare, they aremore common in people of African descent and show a slight female preponderance, usually presenting as solitary and painless masses. Less than 10 % of occurrences are multiple, and fewer than 3 % of tumours behave in amalignant fashion.Themean age, at presentation, is 40–60 years.We report a case of granular cell tumour in a youngwhitemale presenting with a painful soft tissue tumour in his buttock. The presentation is unusual because of the age, patient demographic, body site, and clinical presentation. The clinical and histological aspects are reviewed in the context of this clinical case and the associated literature. 1. Background Granular cell tumours were first described by Abrikossoff in 1926 and are known to occur in skin, connective tissue, breast tissue, and gastrointestinal and genital tracts—with the head and neck being the most common regions. The tongue is the most common site in the head and neck [1]. Granula
