Because of the increasing trend of body contour enhancements with injections, implants, and fillers, clinicians should be on high alert for the possibility of silicone-induced hypercalcemia as one of the differential diagnoses in a patient with history of silicone use. Hypercalcemia as a result of silicone injections has been reported, and there is concern that there will be more cases given the popularity of cosmetic silicone. Cases involved a mother and daughter (70 & 55 years) who presented in 2013 with hypercalcemia after cosmetic silicone injections in 2007. Evaluation showed 1, 25-dihydroxyvitamin D-mediated hypercalcemia and progressive renal dysfunction; lymph node biopsy showed granulomatous silicone lymphadenitis. MRI of the pelvis revealed abnormal signal enhancement within the subcutaneous gluteal adipose tissue and enlarged inguinal lymph nodes. For persistent hypercalcemia and hypercalciuria, surgical resection of silicone material and granulomas is a successful approach to normalize the serum calcium level.
