Description
Summary:A 64-year-old female with complaints of swelling right preauricular region was referred to our tertiary cancer center with fine-needle aspiration cytology (FNAC) report of mucoepidermoid carcinoma and radiological differential of malignant salivary gland neoplasm and sarcoma. On examination, there was a mass over her right parotid region Clinical diagnosis was malignant salivary gland neoplasm. Slide review of FNAC was inconclusive. Biopsy was done. Histopathology showed neoplasm comprising of nests of cells with abundant granular eosinophilic cytoplasm with focal area showing peripherally arranged columnar cells with palisading. On enquiry, the patient gave a history of surgery of right mandible 48 years back. Correlating histopathology and clinical history, a diagnosis of granular cell ameloblastoma was rendered. Radiological evaluation showed a solid-cystic lesion in the right masticator space. Right mandible showed only part of head of mandible consistent with previous surgery. Radical surgery was done. Final report confirmed the biopsy diagnosis.
