Lobular panniculitis with fatty tissue necrosis. Mostly alternating dense infiltrates of clustered foam cells and multinucleated giant cells with radial "needle shaped clefts". Fibroblasts in varying numbers. The needle-like, optically empty spaces correspond to dissolved fatty acid crystals. Rare occurrence of calcifications.

DiagnosisThis section has been translated automatically.

Clinic, histology, regular calcium checks
