A 36-year-old man with carcinosarcoma of the bladder is described. The literature is reviewed and the clinicopathology is discussed. These tumors tend to be bulky, rapidly growing, invasive and recur locally. Metastases are generally hematogenous and may rarely involve regional nodes. Deaths are commonly owing to local invasion and sepsis. Preoperative overstaging may occur and pelvic arteriography and exploration are recommended in questionable cases. Because of the difficulty in locally extirpating these tumors radical cystectomy and urinary diversion are recommended.

We report a 61-year-old Japanese man who died of complications of esophagus cancer surgery. He was well until his 55 years of the age, when he had an onset of speech disturbance and hand writing. He was seen by a neurologist who prescribed Menesit 600 mg/day. His symptoms improved with this medication. In 1993, three years after the onset, he started to show gait disturbance and easy to fall. In 1995, he noted difficulty in eye opening. He visited our clinic on October 26, 1996. On examination, he showed vertical gaze paresis, masked face, nuchal rigidity, small step gait, freezing phenomena, and festination. His mental status was normal. He was treated with 800 mg/day of Menesit, 800 mg/day of L-dops, and 10 mg/day of bromocriptine with little improvement in his symptoms. Cranial CT scan revealed some dilatation of the third ventricle. Subsequent clinical course was one of the slow progression of his parkinsonism. In September of 1997, he noted difficulty in swallowing. He was admitted to the gastrointestinal service of our hospital on October 14, 1997. On admission, neurologic status was essentially similar to the previous one, but he showed more advanced state of his parkinsonism. Upper gastrointestinal series revealed a mass lesion of about 11.5 cm in length protruding into the lower esophagus lumen. Subtotal esophagus resection including the mass was performed on December 2, 1997. The stomach was elevated for anastomosis with the upper esophagus. No metastases were found in the mediastinum except for two lymph nodes in the para-esophageal region. The subsequent course was complicated by marked elevation of GOT, GPT, LDH, total bilirubin as well as direct bilirubin, alkaliphosphatase, and amylase starting in the evening of the surgery. On December 7, leukocytosis and pneumonic shadow were seen involving his right lung. On December 10, he developed cardiopulmonary arrest. He was once resuscitated; however, he developed cardiac arrest again seven hours later and pronounced dead. He was discussed in a neurologic CPC. The chief discussant arrived at the conclusion that the patient had PSP and the cause of the death was ascribed to circulatory disturbance to the liver. The discussant also thought that the terminal course was complicated by cholangitis or cholecystitis, sepsis, and pulmonary embolism. Surgical specimen of the esophagus tumor revealed carcinosarcoma. Postmortem examination revealed yellowish discoloration of the peritoneum and mesenterium, and accumulation of clouded ascites indicating the presence of peritonitis. Inflammatory change extended to the mediastinum. On microscopic examination, various kinds of bacilli and candida spores were seen. The liver was enlarged and a perforation was noted in the gallbladder causing biliary necrosis in the adjacent liver. An extensive infarct was seen in the left lobe of the liver; this was found to be due to obstruction of the hepatic artery at the site of the duodenohepatic mesenterium and obstruction of intrahepatic portal vein secondary to retrograde intrahepatic cholangitis in the left lobe. A piece of surgical threads was seen adjacent to the hepatic artery; foreign body granulomatous reaction was seen surrounding the surgical thread. The rupture of the gallbladder appeared to be due to the obstruction of the left branch of the hepatic artery. Neuropathologic examination revealed extensive degeneration of the pallidum, the substantia nigra, and the subthalamic nucleus and presence of neurofibrillary tangles in the remaining neurons. The neuropathologic findings were consistent with progressive supranuclear palsy, although the pathologic changes in the midbrain tegmentum was only mild gliosis.

A 65-year-old woman was referred to our clinic with gross hematuria. Cystoscopy revealed a non-papillary and non-pedunculated tumor on the left lateral wall of the bladder. A piece of necrotic tissue obtained from the bladder irrigation was histologically squamous cell carcinoma. A perforation at the left lateral wall of the bladder was found on the cystogram. Bone scintigraphy showed multiple metastases and computed tomography scans showed multiple lymph node metastases in the pelvic cavity. The clinical diagnosis was bladder carcinoma of T4N2M1 stage with an abscess due to a spontaneous perforation. Total cystectomy with bilateral ureterocutaneostomy was performed. She died due to sepsis 13 days after the operation. Histologically, the tumor was composed of carcinomatous and sarcomatous elements. The carcinomatous element was compatible with squamous cell carcinoma and the sarcomatous element was composed of undifferentiated malignant spindle cells. Immunohistochemical examination showed that the carcinomatous component was positive for keratin and human chorionic gonadotropin (HCG) and the spindle cell component positive for vimentin, desmin and HCG. Therefore, we diagnosed the tumor as sarcomatoid carcinoma. We reviewed 56 cases of carcinosarcoma of the bladder in Japan and discussed the clinicopathology of the disease.

Pulmonary carcinosarcoma, consisting of both carcinoma and sarcoma with a heterologous element, is a rare subtype, comprising approximately 0.3% of primary lung neoplasia. A 57-year-old man was admitted because of severe dyspnea. A tumor wholly occupying the right thorax was biopsied and diagnosed as pleomorphic sarcoma. The tumor did not respond to chemotherapy, and the patient died of respiratory failure and sepsis. At autopsy, pleomorphic sarcoma was histologically dominant and contained a liposarcoma element confirmed by histocytological and electron microscopic analysis. Adenocarcinoma component with papillary and tubular patterns was confined to the medial lesion of the right lower lobe (3x8 cm), which was found in the chest X-ray 3 years before admission, and had continuously merged with the sarcomatous lesion through the histological transition of both components. Aggressive and rapid growth of the sarcoma derived from the earlier adenocarcinoma became prevalent and contributed to the severe clinical outcome. This is the first documented case of primary lung carcinosarcoma with a liposarcoma element.

Sarcomatoid carcinoma (carcinosarcoma) of the upper urinary collecting system is a rare aggressive malignancy composed of malignant epithelial and stromal components. Because of the paucity of reported cases, the clinical behavior, molecular alterations, and potential therapies for this malignancy are not well understood. Eight cases of sarcomatoid carcinoma involving the upper urinary tract were studied. Clinicopathologic characteristics were reviewed. Immunohistochemical expression of epidermal growth factor receptor (EGFR), human epidermal growth factor receptor 2 (HER2)/neu, c-kit, and p53 was analyzed in each case. Evaluation for amplification of EGFR and HER2 genes was performed by interphase fluorescence in situ hybridization (FISH). Each tumor was also examined for gains of chromosomes 3, 7, and 17 and for loss of chromosome 9p21 by UroVysion FISH (Vysis, Downers Grove, IL). The patients we studied were 5 females and 3 males, ranging in age from 56 to 78 years (mean age, 69 years). Presenting symptoms included gross hematuria, flank mass, urinary obstruction, fever, or sepsis. Radical nephroureterectomy was performed on all patients. Tumor size ranged from 2 to 13 cm. Coexisting urothelial carcinoma was present in all 8 cases. Heterologous osteosarcoma was identified in 2 cases. Pathologic stage was pT4 in 5 cases and pT3 in 3 cases. Lymph node metastases were present in 5 patients at the time of surgery. Of 8 patients, 7 died within 2 years after surgery. EGFR immunostaining had moderately to strongly positive results in 6 of 8 cases. Both HER2/neu and c-kit immunostaining had negative results in all cases. p53 immunostaining had positive results in 5 of 8 cases. The EGFR polysomy was demonstrated in 7 of 8 cases. No amplification of HER2/neu was present in any case. UroVysion FISH showed abnormalities typical of urothelial carcinoma in all 8 cases. In conclusion, the prognosis of sarcomatoid carcinoma of the upper urinary tract is extremely poor, most patients died within 2 years (7/8 patients). Gains of chromosome 3, 7, and 17 and loss of chromosome 9p21 were commonly observed in these tumors. Our findings suggest that targeted therapy may be a rational strategy in the management of these patients.

Herein is presented a case of carcinosarcoma of the pancreas in an 82-year-old woman, analyzed on immunohistochemistry and K-ras sequence. The tumor, which arose in the pancreas head, was removed on pancreaticoduodenectomy. The patient died, however, of disseminated intravascular coagulation syndrome from postoperative sepsis 13 days later. Microscopically, the tumor consisted of malignant epithelial (well-differentiated adenocarcinoma cells) and mesenchymal (spindle-shaped tumor cells) components. The adenocarcinoma cells had positive immunostaining for cytokeratin AE1/AE3, cytokeratin 7, epithelial membrane antigen (EMA), CEA and carbohydrate antigen 19-9 (CA 19-9), while focal staining of these proteins was observed in the sarcomatous cells. In contrast, the sarcomatous cells had diffuse immunostaining for vimentin, CD10 and p53, while these proteins were not expressed in the ductal adenocarcinoma cells. These findings support the dual characteristics of a carcinosarcoma. DNA sequencing of the present case indicated point mutations of K-ras in both codons 12 and 34 on exon 2. The latter mutation is likely to correlate with the sarcomatous characteristics of this tumor. The tumor cells had specific and diffuse positive staining for CD10 and p53, with features characteristic of rapid growth.

We report a 72-year-old Japanese woman with severe hypoglycemia. The laboratory data, which revealed the suppression of serum insulin, suggested the existence of non-islet cell tumor hypoglycemia (NICTH). Abdominal computed tomography demonstrated the presence of a huge uterine tumor. The patient was treated with a continuous infusion of glucose, but died of sepsis on day 46. An autopsy revealed the pathological diagnosis to be a carcinosarcoma of the uterus. Interestingly, an immunohistochemical study discovered the expression of insulin-like growth factor (IGF)-II in both the carcinoma and sarcoma cells. In addition, an immunoblot analysis of blood samples revealed the presence of circulating big IGF-II. Therefore, this is a novel case of NICTH that was caused by a uterine carcinosarcoma.

Metaplastic carcinoma of the breast with mesenchymal differentiation (MCMD), previously known as carcinosarcoma, is a very rare and aggressive tumor that has been recently classified as a subtype of metaplastic breast carcinoma. It accounts for 0.08%-0.2% of all breast cancers, with only a few cases reported in the literature. Histologically, MCMD is characterized by a biphasic pattern of malignant epithelial and sarcomatous components without evidence of a transition zone between the two elements. We herein describe a unique case of metaplastic carcinoma of the breast with chondrosarcomatous differentiation in a postmenopausal woman who presented with a large, rapidly growing, ulcerated, bleeding mass and signs of impending sepsis. Metaplastic breast carcinomas (MBC) are rare and aggressive tumors. They are characterized by larger size, lower rates of axillary node involvement, higher rates of triple negativity and distal metastases, earlier local recurrence and poorer survival compared with classic invasive breast cancer. Because of the rarity of MBC, the optimal treatment has not been well defined. Surgery is the main curative treatment modality since MBC has shown a suboptimal response to standard chemotherapy. Patients with MBC may be appropriate candidates for novel targeted therapies.

Sarcomatoid carcinoma of the gallbladder or gallbladder carcinosarcoma is an exceedingly rare malignancy. Unfortunately, patients typically present with advanced disease at diagnosis. Symptoms may include abdominal pain, jaundice, anorexia, nausea, weight loss, and a palpable abdominal mass. This malignant tumor has a poor prognosis, and treatment options include surgical resection, radiation, and chemotherapy. We detail the case of a 57-year-old male who presented with diffuse abdominal pain and jaundice. Computed tomography scan of the abdomen and pelvis showed a large mass within the gallbladder, intrahepatic ductal dilation, gastrohepatic lymph node enlargement, and liver lesions concerning for metastatic disease. A core needle biopsy from one of the liver lesions revealed poorly differentiated sarcomatoid carcinoma of the gallbladder. He was assessed to have stage IV disease and deemed not to be a surgical candidate. Palliative chemotherapy was planned; however, treatment was never started due to the development of cholangitis with sepsis. The patient ultimately opted for hospice care and passed away shortly thereafter.
