Membranous basal cell adenoma of the hypopharynx

Arch Otolaryngol. 1983 Nov;109(11):774-7. doi: 10.1001/archotol.1983.00800250068017.


A membranous basal cell adenoma arose from the minor salivary glands in the hypopharynx of a 62-year-old man. Features distinguishing the membranous variant from other forms of basal cell adenoma include the following: (1) abundant reduplicated basement membrane material, (2) the presence of sialomucin-containing cells, and (3) the lack of distinct encapsulation. To our knowledge, this is the first report of a basal cell adenoma of the hypopharynx, and the first report of the membranous variant in a minor salivary gland.
