Tumoral calcinosis: a series of six cases with review of pathogenesis and histopathological diagnosis.

Six cases of tumoral calcinosis detected in a short period of time are reported. All the cases were in late adults and mostly in females. Most lesions were in inactive late stage. Available published literature on this rare interesting lesion has been reviewed. The etiopathogenesis and pathological features are discussed. It appears that the strict compartmentalization of lesions into different stages depending on the histological features and the importance of proliferating areas as a marker for progression and recurrence has been over emphasized.
