Serous Cystic Neoplasms of the Pancreas: Can We Distinguish the So-Called Locally- Aggressive Lesions from the Malignant Lesions? Case Series and Proposal of Unified Term “Serous Cystic Neoplasms of Low Grade Malignant Potential”

Serous cystic neoplasms of the pancreas are uncommon lesions and are generally considered benign. Conservative management is generally advised unless it
is symptomatic, rapidly enlarge mass, or uncertain diagnosis. Malignant serous cystadenocarcinoma has been occasionally reported in the literature. However, controversy remains for the definition, diagnosis, and management of the malignant counterpart. Additional proposal for the so-called locally invasive serous cystic neoplasms also add more confusion to the rare entity.
