Pancreatic Panniculitis Secondary to Acinar Cell Carcinoma of the Pancreas

We report the case of a 68-year-old white woman who presented with painful, 1- to 4-cm, erythematous nodules located bilaterally on the anterior and medial shins that had progressively developed and worsened over the last month. Workup revealed pancreatic panniculitis (PP) secondary to acinar cell carcinoma of the pancreas (ACCP). The unique clinicopathologic features, differential diagnosis, underlying causes, associated laboratory and clinical findings, pathophysiology, treatments, and appropriate workup for PP also are reviewed.
