Metastatic calcinosis cutis in a patient with Hodgkin's lymphoma.

Calcinosis cutis results from the deposition of insoluble calcium salts in the skin and subcutaneous tissue. Herein, we report a case of extensive metastatic calcinosis cutis in an 18-year-old woman with stage IV Hodgkin lymphoma with skeletal involvement. With combination therapy including radiation directed at her lymphoma and diltiazem, her lesions improved dramatically. This case demonstrates the previously unreported association between calcinosis cutis and Hodgkin lymphoma.
