CA is characterized by a CK7 negative and CK20 positive (Figure 6B) immunophenotype, and thus can be differentiated from non-ampullary small intestinal adenocarcinomas by their lack of expression of CK7 and positivity for CK20,Table 2 summarizes several key immunohistochemical stains which can help in distinguishing these two entities. In additional to its unique morphologic features, IM also shows a unique immunohistochemical profile. Most of them follow the signal intensity of simple fluid on MRI, but few cysts may demonstrate a high T1 signal due to proteinaceous or hemorrhagic content[16]. The clinical history is usually corroborative of an infectious cause in these cases. Omental cake refers to infiltration of the omental fat by material of soft-tissue density. Mixed exocrine-endocrine tumors are defined as malignant epithelial neoplasms where the ductal and endocrine cells are intimately mixed in the primary tumor with at least one-third to one-half of tumor cells showing positivity for endocrine markers (185). Although rare, angiosarcoma is the most common primary non-hematopoietic malignant tumor of the spleen[7]. Contrast-enhanced CT scan shows multiple well-defined cystic lesions in the perisplenic region invaginating into the spleen (arrows) in a patient with known pseudomyxoma peritonei. Histologically, the tumor has a lobular appearance with well-defined islands of small epithelial cells separated by fibrous bands with a geographic pattern of lighter and darker staining cells due to the different cell types present. Of the malignant lesions metastatic tumors are far more common than primary hepatocellular carcinomas. On ultrasound, hamartomas are usually seen as well-circumscribed homogeneous solid masses[18]. Primary splenic lymphoma usually represents non-Hodgkin lymphoma of B cell origin.

Calcification in splenic metastasis is rare unless the primary tumor is a mucinous adenocarcinoma (Fig. Most MCNs also express MUC5AC while MUC-1 is only expressed in invasive MCNs (151). When this happens, your healthcare provider will begin by physically examining you and follow up with imaging tests (radiology). Bile duct adenomas are also small subcapsular nodules consisting of acini and tubules and may be confused for a malignant lesion (212). Differential diagnosis When this happens, your healthcare provider will begin by physically examining you and follow up with imaging tests (radiology). Pancreatic intraepithelial neoplasia (PanIN) has been speculated to be the precursor lesion of pancreatic ductal adenocarcinomas for over fifty years, but it is only recently that its significance and role in pancreatic carcinoma has been established. The use of immunohistochemistry can help differentiate these as those arising from anal gland adenocarcinoma would be CK7+/CK20+/CDX-2+/GCDFP-15- (119,120), from adnexal adenocarcinoma would be CK7+/CK20-/CDX-2-/GCDFP-15+ and that from a colorectal adenocarcinoma would be CK7-/CK20+/CDX-2+/GCDFP-15+- (119-124).
