Fibroma of Tendon Sheath

Fibroma of Tendon Sheath

David R. Lucas, MD

Fibroma of tendon sheath (FTS) typically presents as a small soft tissue nodule in a finger. This micrograph depicts a circumscribed fibroma image attached to a synovial-lined tendon sheath image.

The proliferating cells in FTS are fibroblasts and myofibroblasts characterized by bipolar spindle and stellate cells with abundant amphophilic cytoplasm and vesicular nuclei with solitary nucleoli.
