Giant Cell Tumor of the Tendon Shealth
- Generally 3-5 decades
- DIP joint most common
- Firm, tender nodule
- Treatment: marginal surgical excision. High recurrence rate.
Giant Cell Tumor of Bone
- Affects epiphysis: distal radius, metacarpal head.
- Rare instances of metastases.
- High recurrence rate
- Xray: expansile, lytic lesion with indistinct borders.
- Treatment: curretage with bone grafting. Consider polymethacrylate cementation, cryosurgery, cauterization. May require en bloc resection +/- allograft reconstruction / wrist fusion.
- Generally occurs in subungal location.
- Generally c/o hypersensitivity of temperature and exquisite pinpoint tenderness with pain that radiates proximally
- Treatment: Excision. High recurrence rate.
Epidermal Inclusion Cyst
- Generally result from penetrating trauma, trapping epithelial cells in the subcutaneous tissues.
- Firm, mobile, painless.
- Treatment: margninal excision.
Enchondroma of the Hand
- Most common benign bone tumor affecting the hand.
- May have thinned cortices which fracture with minor trauma.
- Pathologic fracture of enchondroma of the hand generally treated with immobilization to allow the fracture to heal followed by curettage with bone.
