A granular cell tumour is a tumour of neural origin and is mostly benign and rarely malignant and commonly found in the skin, oral cavity or digestive tract. This report describes a case of a 23-year-old female with a palpable painless mass on the back near the left axilla with progressive growth. While her laboratory tests and radiological were within normal limits histopathological examination revealed round to polygonal PAS positive atypical cells with large vesicular nuclei and coarsely granular cytoplasm along with foci of spindling and necrosis which on IHC were S-100 and CD68 positive and negative for cytokeratin, desmin, EMA. Thus, rendering a diagnosis of a malignant granular tumour of primary origin. This case highlights the importance of accurate histopathological examination to recognise and further categorization of Granular cell tumours along with clinical and radiological correlation.
