CTICasesCalcinosis Cutis Secondary to Acne Vulgaris
Imaging findings
Low-dose screening chest CT reveals diffuse, thickened skin of the anterior chest and back with multiple, focal, well-defined spotty calcifications within the dermis and subcutaneous tissues, alongside several scarring skin 'divots'.
Key takeaways
Calcinosis cutis is a condition characterized by the deposition of calcium in the skin and subcutaneous tissues. In this case, it is a dystrophic calcification process secondary to severe nodulocystic truncal acne vulgaris, which can be seen as an incidental finding on chest CT in older patients with a remote history of severe acne.
