Abstract

We present a case of carpal tunnel syndrome caused by systemic tumoral calcinosis. A 54-year-old woman experienced hand numbness that persisted for nine months. She had no family history or medical problem. A plain radiograph of her right wrist showed a calcified mass on the volar side of the wrist joint. The patient also experienced pain in her contralateral wrist joint and both right and left shoulders, which had calcification on radiography around the joint. Her condition was diagnosed as carpal tunnel syndrome caused by systemic tumoral calcinosis and a resection biopsy was performed. Histopathological analysis of the biopsied specimen showed basophile deposition inside the fibrous connective tissue. At 14 months after the treatment, she no longer had pain or numbness in her fingers and there was no recurrence of the mass. This patient’s condition is considered as a case of nonfamilial, systemic primary tumoral calcinosis. Since incomplete resection leads to a recurrence of the lesion, a follow-up radiography examination is needed to monitor symptom recurrence.
