Seromucinous hamartomas: a clinicopathological study of a sinonasal glandular lesion lacking myoepithelial cells

Abstract

Seromucinous hamartomas show a broader histopathological appearance than previously reported. The serous proliferation in these lesions lacks myoepithelial cells. The presence of occasional REAH-like features and common location in the posterior nasal septum suggest a spectrum from pure seromucinous hamartoma to REAH.
