Cholesterol granuloma is a granulomatous tissue reaction consisting of cholesterol cleft surrounded by foreign body giant cells, foam cells and macrophages filled with hemosiderin pigments. It commonly occurs within the middle ear cavity and temporal bone. We report a case of right antrochoanal polyp which turned out to be a sinonasal cholesterol granuloma in an elderly female patient who presented with a one-month history of unilateral blood-stained nasal discharge. Patient underwent surgical excision of the nasal mass successfully with no complications or recurrence. Albeit rare, cholesterol granuloma should be considered as a differential diagnosis of sinonasal mass.
