Micrograph showing a palmar fibromatosis. H&E stain.

Fibromatoses are a group of benign stromal lesions that may or may not be associated with syndromes.

Syndromes associated with fibromatoses

Types

Superficial

Deep

Gross

  • Firm.
  • Infiltrative borders.

Microscopic

Features:

  • Bland spindle cells - typically in fascicles.
    • Pale eosinophilic cytoplasm.[3]
    • Nucleus may be ovoid.[4]
  • Small thin blood vessels that are parallel to one another.
    • Nuclei of blood vessels are typically darker staining than those of the lesion.

IHC

  • Beta-catenin +ve -- nuclear stain.
  • CD117 -ve.
  • CD34 -ve.[5]

SOFT TISSUE LESION, LEFT SHOULDER, CORE BIOPSY:
- FIBROMATOSIS, SEE COMMENT.

COMMENT:
The lesion was evaluated with immunostains:
Positive: vimentin, SMA (rare), beta-catenin.
Negative: pankeratin, S-100, desmin, CD34 (stains vessels).

Left Foot, Plantar Fascia, Fasciectomy:
	- Plantar fibromatosis.

Micro

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.
