Tumoral calcinosis: case reports from Saudi Arabia with a review of the literature.

Tumoral calcinosis is a rare disease mainly reported among blacks, especially from the tropical and sub-tropical regions of Africa. Hitherto, no reports of this disease entity have been reported from North Africa and the Arab Peninsula. This paper is therefore the first documentation of tumoral calcinosis in nine patients from the Arabian Peninsula; seven of whom are Saudis and two Yemenis. Peculiar osseous and joint changes co-existed in one of the cases. Moreover, there was a high incidence in the feet, in 75% of cases. One of the lesions was quite extensive. Reason for these changes are suggested.
