Abstract
A case of prominent pseudoepitheliomatous hyperplasia (PEH), that was misdiagnosed as squamous cell carcinoma (SCC) on the frozen section occured in the nasal mucosa of a patient suffering with nasal type NK/T cell lymphoma. To prevent misdiagnosis of this lesion, pathologists should be aware that NK/T cell lymphoma may be associated with overlying mucosal PEH, and so the physician must adhere to strict diagnostic criteria for making the diagnosis of SCC. The pathogenesis of PEH associated with NK/T cell lymphoma is not still clear, but it may be related to the production of growth factors, especially epidermal growth factor and transforming growth factor, by the underlying tumors.
