Pleomorphic carcinoma of the pancreas is a well defined histopathological entity characterized by non-cohesive, sarcoma-like growth pattern, and bizarre mono- and multinucleated tumor giant cells with abundant eosinophilic cytoplasm. Fifteen cases are identified in autopsy files of the Department of Pathology, Washington University School of Medicine, which represent 7.1% of all the non-endocrine pancreatic malignancies found at autopsy. Pleomorphic carcinoma is comparable to pancreatic adenocarcinoma in clinical features such as age, sex, and presenting symptoms except that it is more likely to occur in the body and tail of the pancreas, metastases invariably develop, hematogenous spread is more common, and the median survival is worse. Pleomorphic carcinoma could be distinguished from the pancreatic tumors that resemble giant cell tumor of the bone. Differential diagnostic features between it and amelanotic melanoma, hepatocellular carcinoma, choriocarcinoma, pleomorphic liposarcoma, pleomorphic rhabdomyosarcoma, fibroxanthosarcoma, poorly differentiated epidermoid carcinoma, and giant cell carcinomas of the lung and thyroid are discussed.

Pleomorphic carcinoma of lung is a rare subtype that has a propensity to metastasize to the small bowel. This rarely encountered tumor may present a diagnostic challenge to pathologists and result in delay that could impact clinical decisions. Lung cancer can metastasize to any organ in the body; however, clinical manifestations of metastasis to the small bowel are a relatively rare event. Because they are so rare, small-bowel metastases are usually seen only at autopsy. Clinical presentation of small-bowel metastasis of lung cancer may represent a terminal event if not recognized and surgically resolved. Prompt surgical intervention may significantly extend the life of the patient.

Pleomorphic carcinoma is a rare malignancy belonging to the family of nonsmall cell lung cancers. A 40-year-old man, a smoker, was hospitalized for thoracic pain and dry cough with a deteriorating general condition. The imaging showed a "drop ball" of both lungs. The pathological evidence was obtained by lung biopsy under scanographic control. The presence of supraclavicular and abdominal nodes classified the tumour as stage IV. The patient received six cycles of first-line chemotherapy associating cisplatin and vinorelbine. However, the disease continued to progress and distant metastases were observed. The patient died 6 months after the diagnosis. Pleomorphic carcinoma is identified by purely histological criteria: the concomitant presence of malignant epithelial and homologous sarcomatoid spindle-cell components. Like the other nonsmall cell lung cancers, the treatment is primarily surgical, and the invasive nature of this tumour makes it very difficult. Pleomorphic carcinoma has a poorer prognosis than conventional nonsmall cell lung cancers despite surgery, irradiation and chemotherapy, because relapse occurs early.

Pleomorphic carcinoma is a rare primary lung cancer with a poor prognosis. We report a surgically treated case of pleomorphic carcinoma of the lung. An abnormal shadow was incidentally detected by computed tomography (CT) scan for an 80-year-old male. CT scan performed 1 month before the detection of tumor was normal. Right upper lobectomy with ND2a was performed after 5 months follow-up by CT scan because of the enlargement of the tumor. Histological examination showed numerous atypical spindle cells with massive necrosis, diagnosing as pleomorphic carcinoma. Only 2 months after operation, multiple metastases to the lung, chest wall, pleura, and small intestine were found.

Pleomorphic carcinoma is a rare aggressive type of lung cancer that uncommonly metastasizes to the bowel, leading to bleeding, perforation, obstruction, and rarely intussusception. Serving as a lead point, metastatic lesions in the bowel may precipitate intussusception and require immediate surgical intervention. We present a rare case of colonic metastases from a primary lung malignancy, causing ileocecal intussusception in a 57-year old male.

Pleomorphic carcinoma is rare in the primary lung cancer with a poor prognosis. We reported a resected case of pleomorphic carcinoma of the lung with rapid progression. A 62-year-old male with a tumor shadow in the right lung which had not been noted 9 months before was referred to our hospital. The abnormal shadow was not noted 9 months ago. The tumor located in the right lower lobe and rapidly enlarged from 7.5 cm to 9.5 cm in a month. Right pneumonectomy was necessary, because of the intrapulmonary metastasis in the right upper lobe. Pathological findings showing spindle cells with massive necrosis, were consistent with a diagnosis of pleomorphic carcinoma. Only by 45 days after operation, local recurrence and metastases to the brain, right adrenal gland and small intestine were found, resulting in death at 67 days after operation.

Pleomorphic carcinoma is a rare lesion and the literature contains few reports of pleomorphic carcinoma of the gallbladder. The present study reports a rare case of primary pleomorphic carcinoma of the gallbladder for which we were able to perform curative surgery. A 77-year-old woman with dementia developed nausea and anorexia, and computed tomography demonstrated irregular thickening of the gallbladder wall. Drip infusion cholangiography and endoscopic retrograde cholangiopancreatography revealed no stenosis of the common and intrahepatic bile ducts. We suspected carcinoma of the gallbladder without lymph node metastasis and invasion to the common bile duct. We guessed it to be resectable and performed open laparotomy. At operation, the fundus of the gallbladder was adherent to the transverse colon, but no lymph node and distant metastases were detected. Therefore, we performed curative cholecystectomy with partial colectomy. Histopathology and immunostaining showed coexistence of an adenocarcinoma, squamous cell carcinoma and sarcomatous tumor of spindle-shaped cell, as well as transition zones between these tumors. We diagnosed stage I pleomorphic carcinoma of the gallbladder. No recurrence has been observed for one and a half years. The biological behavior of pleomorphic carcinoma of the gallbladder remains unknown. It will be necessary to accumulate more case reports of this tumor in order to define diagnostic criteria.

Pleomorphic carcinoma is a rare and very aggressive subtype of lung cancer that tends to grow rapidly and invade adjacent structures. Here we report a case of pleomorphic carcinoma with rapid growth, multiple metastases, and intestinal perforation. A 46-year-old man was admitted to our hospital because of lung abscess. Several antibiotics were administered for 2 weeks, but his condition did not improve. F18-fluorodeoxyglucose positron emission tomography revealed high uptake in the right lung, stomach, and pancreas. CT-fluoroscopic lung biopsy was performed, and a diagnosis of pleomorphic carcinoma was made. His performance status worsened each day, and the lung tumor grew within 1 month. In addition, sudden severe abdominal pain and tenderness developed 10 days after lung biopsy. He was diagnosed with gastrointestinal perforation, and he underwent surgery. However, he died 2 weeks after the surgery. Autopsy revealed the presence of an enormous tumor in the right lung and multiple metastases in the stomach, duodenum, intestine, bilateral kidneys, pancreas, gallbladder, right adrenal gland and thyroid.
