Pancreatic cystic neoplasms Part 3 - Serous cystic neoplasms and SPEN pancreas - Pancreatic tumors

The pancreatic cystic neoplasms series continues here with the third part now discussing serous cystic neoplasms and SPEN pancreas.
Serous cystic neoplasms (SCNs) are a type of pancreatic cystic lesion that can be found in the pancreas. These neoplasms are typically benign (non-cancerous) and are characterized by cysts filled with clear, watery fluid. SCNs are more commonly seen in women and are often incidentally discovered during imaging studies such as abdominal ultrasound, CT scans, or MRI.
Key features of serous cystic neoplasms include:
Cystic Appearance: SCNs typically appear as well-defined cystic lesions on imaging studies, often with a honeycomb or microcystic appearance. They can vary in size from a few millimeters to several centimeters.
Clear Fluid Content: The cysts in SCNs are usually filled with clear, watery fluid. This distinguishes them from other types of pancreatic cysts that may contain mucin or solid components.
Benign Nature: Most SCNs are benign and do not progress to cancer. However, there is a small risk of malignant transformation, particularly in larger lesions or those with atypical features.
Microscopic Features: Microscopically, SCNs are characterized by the presence of glycogen-rich cuboidal epithelial cells lining the cysts. This histological appearance helps to distinguish them from other types of pancreatic cystic lesions.
Symptoms and Complications: Many SCNs are asymptomatic and are incidentally discovered on imaging studies performed for other reasons. However, larger lesions may cause symptoms such as abdominal pain or discomfort. Rarely, SCNs can become large enough to cause complications such as obstructive jaundice or compression of adjacent structures.
Management: The management of SCNs depends on various factors, including the size of the lesion, presence of symptoms, and risk of malignancy. Small, asymptomatic SCNs may simply be monitored with periodic imaging studies to assess for any changes in size or appearance. Surgical resection may be considered for symptomatic or larger lesions, as well as in cases where malignancy cannot be ruled out.
Overall, serous cystic neoplasms of the pancreas are typically benign lesions with a favorable prognosis.
A solid pseudopapillary neoplasm (SPN) of the pancreas is a rare type of pancreatic tumor that typically affects young women, although it can occur in individuals of any age or gender. It is also known by various other names, including solid and cystic tumor, solid and papillary epithelial neoplasm, Frantz tumor, or Hamoudi tumor.
Here are some key points about solid pseudopapillary neoplasms of the pancreas:
Appearance: SPNs are typically well-circumscribed, solid tumors with areas of cystic degeneration. They may have a mixture of solid and cystic components when viewed on imaging studies such as CT scans or MRI.
Histology: Microscopically, SPNs are characterized by the presence of solid and pseudopapillary structures composed of uniform epithelial cells with delicate vascular cores. The cells often have eosinophilic cytoplasm and show immunoreactivity for certain markers such as CD10, vimentin, and β-catenin.
Clinical Presentation: Many SPNs are discovered incidentally on imaging studies performed for unrelated reasons. However, they can sometimes present with nonspecific symptoms such as abdominal pain, a palpable mass, or symptoms related to compression of adjacent structures.
Prognosis: Solid pseudopapillary neoplasms of the pancreas are typically considered low-grade malignant tumors. While they have the potential to metastasize, they are usually associated with a favorable prognosis after surgical resection. The overall survival rate for patients with SPNs is high.
Treatment: The primary treatment for SPNs is surgical resection, which can often be curative, especially if the tumor is detected early and has not spread beyond the pancreas.
