A case of symptomatic tumoral calcinosis on the great toe and review of the literature.

A 67-year-old woman with no specific medical history showed a hard mass on her great toe for several years. The lesion was elastic, round, and had good mobility. An X-ray showed the lesion to be a calcified "chicken wire" lesion; CT and MRI findings indicated it as a benign subcutaneous calcified tumor. Therefore, a resection biopsy was performed. The mass was a 20 x 20 mm calcified tumor diagnosed as tumoral calcinosis. Pathological findings showed that the calcified lesion lay in fibrous connective tissue and characteristic cells were seen around the calcification site. In this case, the lesion was mature and surgical resection was successful. The patient showed no symptoms or recurrence 3 years after the surgery.
