Immature Teratoma of Ethmoid Sinus Masquerading as Antrochoanal Polyp: A Rare Case Report with Literature Review

AbstractTeratomas are rare neoplasms that arise from totipotent stem cells. Teratomas of the head and neck are extremely rare, constituting about 10% of all cases and usually present in the neonatal period. Extensive literature search has shown that there are only two cases reportedof teratoma of the ethmoid sinus; one as a mature teratoma in a neonate and another was histologically immature teratoma in an adult male (Mwang ’ombe et al. in East Afr Med J 79(2):106–107, 2002; Aggarwal et al. in J Postgrad Med 59(2):138–141, 2013). We hereby report the second case of immature teratoma of ethmoid sinus origin in an adult male.
