Metastatic Pancreatic Acinar Cell Carcinoma: An Unlikely Culprit.

Although acinar cells comprise a large volume of the pancreas, they rarely transform into malignant neoplasms. Once they arise, they rapidly metastasize via hematogenous spread to other organs such as the brain, liver, lung, and skeletal system. Cutaneous involvement, however, is rarely seen in all patients with primary pancreatic neoplasms. The most frequently reported site of cutaneous manifestations is the umbilicus, with the other sites including the trunk, lower extremities, head, and neck. Here, we report a case of metastatic pancreatic acinar cell carcinoma with cutaneous involvement of the patient's scalp.
