Idiopathic calcinosis cutis of the vulva in an elderly woman. A case report.

BACKGROUND

Idiopathic calcinosis cutis of the vulva is a rare condition of unknown etiology. Only seven cases have been reported to date, and all of them were in children. We report the first case in an elderly woman.

CASE: A 68-year-old woman presented with a labial lesion of unknown etiology. Excisional biopsy was performed, and histopathologic evaluation showed subepidermal calcification. Follow-up biochemical and hormonal analysis and screening tests for collagen vascular diseases revealed normal results.

CONCLUSION

After diagnosis of calcinosis cutis, a laboratory workup to rule out abnormalities of calcium and phosphorus metabolism, malignant processes and collagen vascular diseases must be carried out. This approach in the evaluation of calcinosis cutis could lead to diagnosis of the underlying disease at an early stage.
