title: Tumoral calcinosis with vitamin D deficiency.
abstract: A 50-year-old woman presented with recurrent calcified mass in the left gluteal region. The clinical, radiological, and biochemical profile confirmed the diagnosis of tumoral calcinosis. She also had associated vitamin D deficiency. The patient underwent surgical removal of the mass to relieve the sciatic nerve compression and was managed with acetazolamide, calcium carbonate, and aluminium hydroxide gel with which she showed significant improvement. The management implications and effect of vitamin D deficiency on phosphate metabolism in the setting of tumoral calcinosis is discussed.
