Definition

Sclerotic fibroma is a rare, benign soft tissue tumour composed of eosinophilic collagen bundles arranged in a storiform pattern with minimal cellular atypia. It is typically a small (<1cm diameter) translucent, white nodule and occurs in both sexes at any age. Sites of involvement include the face, upper and lower extremities and trunk.
Multiple tumours are typical of the inherited Cowden syndrome .
