Tumoral calcinosis in postmenopausal women in urban India: an etiopathologic evaluation of 64 cases.

ABSTRACT

Tumoral calcinosis (TC) is a distinct pathologic entity of obscure etiology, characterized by soft tissue calcium deposition. We analyzed 64 cases retrieved from surgical records over the last 15 years, to assess the disease pattern and recognize the various stages of the evolution of this lesion. In our study, most patients were women (53/64 cases), 47 of whom were postmenopausal, aged 51-70 years, belonging to lower socioeconomic strata, and involved with household chores. The hip was the most frequently affected site. Repeated trauma probably triggered calcium chelation and deposition at this site. Histologically, 10 cases belonged to stage II and 54 cases to stage III. Fully developed lesions showed chips of calcium surrounded by thick fibrosis, mimicking calcified parasite like the Guinea worm. Precursor lesions seen at the periphery of the main lesion suggests a possible etiological role for trauma. Postmenopausal hormonal imbalance, along with poor nutrition and repeated trauma led to TC in our women population. Awareness of its evolution can lead to a better understanding of the disease with possible therapeutic implications.
