Fibromatoses are a group of benign stromal lesions that may or may not be associated with syndromes.
Plantar fibromatosis redirects here.
Syndromes associated with fibromatoses
- Familial adenomatous polyposis.[1]
- Hereditary desmoid syndrome.
Types
Superficial
- Palmar (Dupuytren's contracture).
- Plantar (Ledderhose disease[2][3]).
- Penile (Peyronie's disease).
Deep
- Desmoid-type fibromatosis.
- Others.
Gross
- Firm.
- Infiltrative borders.

Microscopic
Features:
- Bland spindle cells - typically in fascicles.
- Small thin blood vessels that are parallel to one another.
- Nuclei of blood vessels are typically darker staining than those of the lesion.
DDx:
- Metaplastic carcinoma, e.g. metaplastic breast carcinoma.
- Nodular fasciitis.
- Dermatofibroma.
- GIST.
- Desmoplastic fibroblastoma - esp. shoulder region.
Images:
- Plantar fibromatosis (sarcomaimages.com).
- Mesenteric fibromatosis (flickr.com).
- Plantar fibromatosis (rsna.org).[5]
- Plantar fibromatosis (rsna.org).[5]
IHC
- Beta-catenin +ve -- nuclear stain.
- CD117 -ve.
- CD34 -ve.[6]

The sections show a lesion with bland spindle cells. There is no apparent nuclear atypia. Mitotic figures are not identified. No myxoid areas are apparent. No necrosis is identified.
