Introduction: Calcium deposition in the skin has been termed as calcinosis cutis. Tumoral calcinosis is idiopathic form of calcinosis cutis. Etiology of idiopathic calcinosis cutis is unknown. It is characterized by periarticular deposition of amorphous calcium salts around large joints. Our diligent search through literature could not find any consensus on the etiopathogenesis and treatment modalities for tumoral calcinosis.
Materials and Methods: A retrospective study of seven patients of tumoral calcinosis treated with complete surgical excision over a period of 1 year was done. Demographic details were compiled. Routine blood investigations were performed. All patients underwent radiographs and magnetic resonance imaging (MRI) scans of involved part. We did not perform computed tomography (CT) or bone scan in any of our patients. All seven patients underwent surgery and were followed up till 2 years.
Results: In our study, five were female and two were male patients ranging from 31 to 76 years. Size of swelling varied from 2 to 15 cm. Most common location was hip. Serum calcium, phosphorus, and alkaline phosphatase were normal in all patients. Radiographs showed well-outlined periarticular cluster of calcifications in the soft tissues around joint. MRI revealed round to oval multiple cystic lesions around the affected region, but not involving the joint.
Conclusion: Tumoral calcinosis is always the diagnosis of exclusion. It can be normophosphatemic or hypophosphatemic subtype. Large joints are more commonly affected. One can rely on radiographs for diagnosis. MRI for knowing exact location of lesion, its relationship with adjacent structures and planning of surgery is advocated. Complete surgical excision is the only optimum treatment of tumoral calcinosis.
