title: Tumoral calcinosis of the foot: An unusual differential diagnosis of calcaneal mass.
abstract: BACKGROUND
  Tumoral calcinosis (TC) is a rare disorder characterized by the development of calcified masses within the periarticular soft tissues of large joints. It commonly involves the hip, shoulders, and elbows. TC rarely involves the feet.
  
  
  METHODS
  In this report, we describe an unusual case of primary TC of the foot in a 76-year-old female and discuss the pathophysiology, diagnosis, and therapeutic interventions of the condition.
  
  
  CONCLUSIONS
  Due to the wide range of conditions mimicking TC, its diagnosis could be challenging. Diagnosis of TC is mainly based on the radiographic findings, the patient's biochemical profile, and the medical history plus differentiating the condition from its mimics.
  
  
  CONCLUSIONS
  TC should be considered in the differential diagnosis of any soft tissue calcification.
