Medical condition
Acinar cell carcinoma of the pancreas |
---|
Acinar cell carcinoma of the pancreas, also acinar cell carcinoma, is a rare malignant exocrine tumour of the pancreas. It represents 5% of all exocrine tumours of the pancreas, making it the second most common type of pancreatic cancer.[1] It is abbreviated ACC. It typically has a guarded prognosis.
Symptoms
CT scan in a patient with acinar cell carcinoma
The disease is more common in men than women and the average age at diagnosis is about 60.[2]
Symptoms are often non-specific and include weight loss. A classic presentation, found in around 15% of cases includes subcutaneous nodules (due to fat necrosis) and arthralgias, caused by release of lipase.[3]
Pathology
ACC are associated with increased serum lipase and manifest in the classic presentation as the Schmid triad (subcutaneous fat necrosis, polyarthritis, eosinophilia).[4]
ACC are typically large, up to 10cm, and soft compared to pancreatic adenocarcinoma, lacking its dense stroma. They can arise in any part of the pancreas.[5]
Histomorphologically, the tumour resembles the cells of the pancreatic acini and, typically, have moderate granular cytoplasm that stain with both PAS and PASD.[6]
Treatment
ACC can be treated with a Whipple procedure.
