A case of inflammatory malignant fibrous histiocytoma of the ileum seemingly induced by radiation is described. A 50-year-old female with a past history of uterine cervical carcinoma and postoperative radiation therapy presented with abdominal pain, fever and leukocytosis. The subserosa of the distal part of the ileum showed a diffuse dense, neutrophilic and lymphocytic infiltrate with dispersed atypical, short spindle- or plump oval-shaped histiocyte-like cells. Pleomorphic mono- or multinucleated giant cells with bizarre nuclei were also intermingled in the lesion. Immunohistochemically, the tumorous atypical cells were positive for vimentin, alpha-smooth muscle actin, alpha-1 antitrypsin and granulocyte colony-stimulating factor. No EBV genomic sequences were detected by in situ hybridization. Flow cytometry showed an aneuploid DNA content with high S-phase fraction. The patient was well with no evidence of tumor at 5 months after surgery. It is important to include this type of tumor in the differential diagnosis of small intestinal lesions accompanied by fever and leukocytosis following radiation.

Secondary amyloidosis is an occasional complication of ankylosing spondylitis (AS) and in most cases renal amyloidosis presents with proteinuria, nephrotic syndrome and decreased renal function. We describe a 32-year-old male patient with AS manifested by frequent diarrhea, intermittent abdominal pain and low serum albumin levels. He has suffered from severe inflammatory back pain for 14 years with multiple peripheral joint involvement. Protein-losing enteropathy due to gastrointestinal amyloidosis was diagnosed with 99mTc-human albumin scintigraphy, fecal alpha-1 antitrypsin clearance and colonoscopic biopsy with Congo red staining. Somatostatin analogue octreotide and prednisolone were introduced with successful result.

Liver tissue ectopia is a well-documented phenomenon. Rarely, hepatocellular carcinoma arises from the ectopic liver tissue. In this paper, we report a case of a primary, well-differentiated hepatocellular carcinoma arising from ectopic liver tissue in the pancreas. The patient is a 58-year-old Hispanic man with no history of underlying liver diseases or chronic pancreatic diseases. Patient presented with a several days history of abdominal pain with radiation to his right upper quadrant. Imaging study revealed a 3.7 x 3.3-cm mass in the distal pancreas. No other lesions were identified. Preoperative fine needle aspiration revealed blood and atypical hepatocytes. The patient underwent distal pancreatectomy and splenectomy for suspected neuroendocrine tumor. Gross examination revealed a well-circumscribed 3.3-cm, beige-tan, pseudolobulated tumor with focal areas of hyperpigmentation. A microscopic examination revealed hepatoid cells arranged in a trabecular pattern with focal bile pigment. Immunohistochemistry study showed that the tumor cells were reactive with hepatocyte antigen (Hep par 1), alpha-1 antitrypsin, but negative for synaptophysin and chromogranin. Immunostain for polyclonal carcinoembryonic antigen showed a typical bile canalicular pattern. These results support that this tumor in the pancreas is hepatocellular carcinoma, most likely arising from ectopic liver tissue within the pancreas.

Primary malignant fibrous histiocytoma (MFH) of the liver remains extremely rare with only several cases having been reported in literature. We report a case of hepatic MFH in a 53-year-old man who presented with upper abdominal pain, and weight loss for one month. Ultrasound and computed tomography (CT) scan showed a large mass with fine tumor vessels over the left lobe of the liver. Histopathological findings indicated a mesenchymal tumor consisting of spindle cells in storiform pattern intermingled with histiocyte-like cells and giant cells. Immunohistochemically, most tumor cells expressed vimentin, alpha-1 anti-chymotrypsin, alpha-1 antitrypsin and CD68. Morphological and immunohistochemical findings support that the tumor should be classified as a primary malignant fibrous histiocytoma. The literatures is briefly reviewed.
