The origin of hidradenoma was from the eccrine sweat glands, generally found in the head, face, and upper extremity regions. This lesion has not been reported to be large enough to present in the ear lobule. Hence, its description in the otolaryngology literature is extremely rare. The rarity of this neoplasm and failure to identify its morphologic features may lead to misdiagnosis. We present a benign clear cell hidradenoma of the right ear lobule in a 45-year adult male. We encountered a tumour measuring 4 cm in diameter. Mass shows ulcerated surface, bleeds on touch and remained a diagnostic dilemma till an excision biopsy was carried out and a histopathological report confirmed that it was a hidradenoma of clear cell variant. The aim of presenting this case report was interesting in the fact that it has added clear cell hidradenoma in the final diagnosis, in an uncommon site of presentation.
