Abstract

Tumoral calcinosis is a type of idiopathic calcinosis cutis which usually occurs around the large joints due to deposition of calcium phosphate, but extremely rare in the fingers which has been reported less than 20 cases in the literature. When it occurs on the fingers, it shows almost normal skin appearance and no specific symptoms except localized tenderness and numbness, therefore it is difficult to differential diagnosis among other common tumors on the fingers. In most cases surgical excision is performed before final diagnosis, and it is easy to misdiagnosis. The patient had mass like lesion which is enlarging for last 2 years at the radial side of the second finger without any trauma history. We prediagnosed the tumoral calcinosis with the simple radiologic test and laboratory tests and performed surgical excision without recurrence. So we report a case of tumoral calcinosis of the radial side of the second finger with brief review of the literature.

Figure

• 

  Fig. 1. (A, B) Preoperative appearance of the lesion at the radial side of the proximal interphalangeal joint of left index finger. There was paresthesia on the ipsilateral distal area of the tumor and physical examination revealed a firm, round and tender mass.

• 

  Fig. 2. Standard radiographs showed a well-demarcated, oval-shaped, densely opacified mass on the proximal interphalangeal joint of the left index finger. (A) Antero-posteriorview. (B) Oblique view.

• 

  Fig. 3. (A) Intraoperative findings. Yellowish thin capsulated calcified mass with irregular surface was located on subcutaneous level without adhesion to surrounding tissue, and well demarcated. (B) The size of the mass was 12×11 mm. The yellow capsule con-tainedchalkyfluid.

• 

  Fig. 4. (A) The mass consisted of calcified material and fibrous tissue (H&E, ×10). (B) Fibrous tissue and multi-nucleated giant cells appeared around the calcified material (H&E, ×200).
