Primary sinonasal clear cell carcinoma is a rare neoplasm
classified under malignant epithelial tumours of salivary
gland – type carcinomas under World Health Organization
(WHO) classification. We report a case which occurred on a
69 year old gentleman presented with epistaxis and nasal
endoscopy examination showed tumour arising from the
right ethmoid cells. Endoscopic excision of the tumour was
done and histopathological examination revealed clear cell
carcinoma. In addition, other secondary or primary sites of
the lesion were excluded by clinical, immunohistochemical
and radiological examinations. 10 months into the
postoperative period, patient remains well without
recurrence of the tumour. In conclusion: We report a rare
case of primary sinonasal clear cell carcinoma in addition to
the limited literature available and emphasize the
differentials with other probable tumour through meticulous
microscopic examination and use of special immunostains.
