Abstract
Storiform collagenoma (also called sclerotic fibroma) is uncommon, occurs as a cutaneous
fibrous neoplasm, and is particularly rare in mucosal tissue in the head and neck.
We describe an unexpected diagnosis in the oral cavity. Histopathological examination
showed a proliferation of fibrous tissue, which was well circumscribed but unencapsulated,
with thick laminated bundles of eosinophilic collagen that exhibited a storiform or
“whorled” pattern. First described by Weary et al in 1972, storiform collagenoma is
a marker for Cowden’s disease or PTEN hamartoma tumour syndrome. Identification of
other synchronous lesions should prompt chromosomal analysis for a mutation in the
PTEN gene on chromosome 10q23.
