A case of a 60 year old man with malignant eccrine spiradenoma involving the perineum is described. Areas of typical eccrine spiradenoma were admixed with carcinomatous and sarcomatous elements. Immunohistochemical and ultrastructural analysis revealed no evidence of epithelial differentiation in the sarcomatous areas. The tumour qualified for the designation
carcinosarcoma
arising in eccrine spiradenoma. The clinical course was aggressive with rapid development of nodal and pulmonary
metastases
.

A malignant phyllodes tumour with a noninvasive ductal carcinoma component is reported. The patient was an 80-year-old Japanese woman with a breast tumour detected by routine physical examination. A simple mastectomy was performed. The excised tumour was 10.5 x 9.4 x 5.4 cm in size and bulged into the skin with ulceration. The macroscopic appearance was that of a phyllodes tumour. Histologically the tumour consisted mainly of stromal components with a leaf-like structure lined by atypical ductal epithelium. The epithelial component showed gradual evolution to intraductal papillary carcinoma in a few areas. The stromal component was composed mainly of fibrosarcoma with areas of osteosarcoma and rhabdomyosarcoma. Neither stromal invasion of intraductal carcinoma nor transition between the stromal and epithelial elements was seen. Three months after the operation, death occurred, with multiple pulmonary and subcutaneous
metastases
. This case probably represents malignant change in both the stromal and the epithelial components of a phyllodes tumour. Since the two elements were independent, the possibility that a phyllodes tumour may be one of the origins of true
carcinosarcoma
is raised.

Experiments were performed in order to evaluate the effects of fluoxetine, a selective inhibitor of neural serotonin transporter antidepressant, on the development lung metastases in rats subjected to laparotomy and injected (i.v.) with 10(4) Walker 256 (W-256)
carcinosarcoma
cells. The number of metastatic nodules on the surface of the lungs, as well as the percentage-area of
metastases
in the frontal section through pulmonary hilus were increased in rats subjected to sham-surgery or laparotomy. Treatment with fluoxetine (5 mg/kg) partially reversed those adverse effects of surgery, but the difference was clearer when it was administered before surgery was performed. Survival periods were also assessed and fluoxetine was found to decrease the lethality of rats exposed to surgery.

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.

Salivary gland
carcinosarcoma
, or true malignant mixed tumor, is a very rare and extremely aggressive neoplasm. The clonality and clonal origin of this tumor are discussed controversially. We report a
carcinosarcoma
of the left parotid gland in a patient who subsequently died of cutaneous, lymphatic and pulmonary
metastases
. Immunohistochemical staining, electron micrograph analysis, loss of heterozygosity (LOH) analysis and sequence analysis were performed on this tumor with an adenocarcinomatous and a predominant spindle cell-like component. While smooth muscle actin was undetectable by immunohistochemistry, cytoplasmatic myoepithelial structures could be detected by electron microscopy. LOH analysis at 12 genomic locations detected complete deletion of one allele at 17p13.1, 17q21. 3, and 18q21.3 indicating allelic loss in both components of the tumor. Double strand sequencing of the remaining allele of the p53 tumor suppressor gene revealed a wild-type allele. Based on our results, we favor the hypothesis of monoclonal origin of this salivary gland
carcinosarcoma
with a common stem cell that could be the myoepithelial cell and an inactivated tumor suppressor gene on chromosome 17 other than p53.

Thirteen patients with malignant mixed mullerian tumor of the female genital tract, treated and followed in our clinic from 1989 to 1999 were retrospectively evaluated. Seven patients (53.8%) with advanced disease or postoperative residual tumor were treated with adjuvant chemotherapy. The median age at diagnosis was 64 years (range: 26-79). All patients underwent primary surgical cytoreduction. Tumors were localized to the endometrium in five (62.5%), to the ovaries in two (25%) and to the fallopian tube in one (12.5%) patient. One patient with endometrial
carcinosarcoma
had a simultaneous second primary ovarian epithelial carcinoma. Two patients (25%) had a heterologous sarcomatous component. Myometrial involvement included less than half the thickness in one patient, while there was no myometrial invasion encountered in two patients. Five patients (38.5%) had more than 50% of the myometrium invaded. Two patients received additional radiotherapy. Six patients received cisplatinum-based chemotherapy (4 had doxorubicin including combinations), while one patient was treated with a doxorubicin+ifosphamide combination. Five patients (71.4%) had a complete response (CR) to chemotherapy. Response duration in patients with a CR was +13, +67, +10, +14 and +2 months, respectively. After a median follow-up period of 20 months (3-115 months), six patients have died, five are being followed-up with no evidence of disease, one is alive with
metastatic disease
and one patient is under treatment. Malignant mixed mullerian tumor of the female genital tract is highly responsive to multimodality treatment strategies. Further prospective studies are required to identify distinct prognostic groups that may benefit from various treatment modalities.

We report a case of
carcinosarcoma
of the urinary bladder. A 68-year-old man visited our hospital with complaints of asymptomatic macroscopic hematuria, cold sweat and general malaise. Excretory urography revealed a filling defect in the left wall of the bladder, and subsequent cystoscopy revealed a non-papillary sessile tumor. The tumor was transurethrally resected and its histology showed
carcinosarcoma
which was characteristics of a mixture of transitional cell carcinoma with spindle cell sarcoma. The patient underwent total cystectomy and his bladder was reconstructed with the ileum. Nevertheless, he died of multiple organ
metastases
3 months after the surgery.

We report a case of true malignant mixed tumour (
carcinosarcoma
) of the parotid gland with epithelial-myoepithelial carcinoma and pleomorphic sarcomatous components in a 68-year-old woman. The pleomorphic sarcomatous component behaved aggressively with lymph node and distant
metastases
. The biological behaviour of the individual components in a malignant mixed tumour makes it difficult to diagnose. We could find no previous report of epithelial-myoepithelial carcinoma as a component of a
carcinosarcoma
of the parotid.

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.

A 45-year-old woman presented with a short history of abdominal distension and features of intestinal obstruction. Computed tomography examination of the abdomen revealed a solid and cystic mass in the region of the left ovary, but spread within the abdomen was also noted. The ovarian tumor was removed, and an omentectomy was also performed. Microscopic examination of the ovarian tumor and
metastases
within the omentum showed a
carcinosarcoma
composed of borderline serous papillary cystadenocarcinoma and angiosarcoma. The angiosarcomatous component was the dominant tumor within the omentum. This case documents an unusual combination of epithelial and sarcomatous elements in an ovarian carcinosarcoma. The tumor behaved aggressively because of the angiosarcomatous component, and since the patient was assessed as having stage IV disease, no further treatment was offered.
