Uremic tumoral calcinosis of the foot mimicking infection

Uremic tumoral calcinosis is an uncommon, benign condition characterized by slow-growing calcified periarticular soft tissue masses of varying size. We describe two patients with chronic renal failure on hemodialysis presenting uremic tumoral calcinosis, one in the fifth toe of the right foot and the other in the dorsum of the left foot between the first and second metatarsals. Excision of the calcic masses and parathyroidectomy were successfully performed in both patients. These cases are unusual in their rapid onset, mimicking acute infection. Differential diagnosis, radiological features and therapy are discussed.
