A Case of Fibroma of Tendon Sheath on the Big Toe / 대한피부과학회지

ABSTRACT

Fibroma of tendon sheath presents as a small subcutaneous nodule that slowly increases in size, and it is most frequently found on the hands, with the thumb being the most common site of involvement. A 60-year-old woman presented with an asymptomatic, solitary, 1.5 x 2.0 cm-sized, firm, subcutaneous nodule on the left big toe. On magnetic resonance imaging view, the tumor was adherent to tendon sheath of the volar aspect of the left big toe. The skin biopsy specimen showed that the well-circumscribed tumor contained hypocellular, hyalinized, collagenous area and hypercellular densely-arranged collagen area with spindle-shaped fibroblasts and slit-like vascular channels. We herein report a rare case of fibroma of tendon sheath on the left big toe.
