[Pulmonary carcinosarcoma with jejunal metastasis: complete response to chemotherapy].

We report a case of pulmonary carcinosarcoma with jejunal metastasis. The lung is an exceptional localization for carcinosarcoma, a tumor with carcinomatous and sarcomatous components. These two components are closely related but well-defined morphologically and immunohistochemically. Risk of metastasis and local recurrence is high. Surgery is the treatment of choice for localized forms. Prognosis depends on the sarcomatous component which is usually sensitive to chemotherapy, with at least doxorubicin and ifosfamide. This rare case illustrates the potential for jejunal metastasis and complete response to chemotherapy, proven histologically at 33 months.

[True pulmonary carcinosarcoma suspected as a metastatic lung tumor].

This patient, a 53-year-old man, has underwent operation on the diagnosis of esophageal cancer 2 years ago. An abnormal shadow was detected in the left lung field and he was admitted to our hospital for further examination. On the suspicion of metastatic lung tumor by transbronchial brushing cytology, partial resection of the left lower lobe was performed. Histologically the tumor was of carcinomatous (squamous cell carcinoma and adenocarcinoma) and sarcomatous (fibrosarcoma and chondrosarcoma) elements, so the patient was diagnosed as "true" pulmonary carcinosarcoma. True pulmonary carcinosarcoma is one of the very rarest neoplasms of the lung.

Cytologic appearance of carcinosarcoma (malignant ameloblastoma and fibrosarcoma) of the maxilla. A case report.

The cytologic appearance of a carcinosarcoma (malignant ameloblastoma and fibrosarcoma) of the maxilla in a 63-year-old man is described. On his first admission the diagnosis of malignant ameloblastoma was made on biopsy. After five surgical excisions, radiotherapy and chemotherapy, the diagnosis was changed to carcinosarcoma because the stromal cells of the tumor had become malignant. Aspiration biopsy cytology of the tumor, with a cystic lesion found at the left suborbital area, revealed malignant epithelial cells, indicating malignant ameloblastoma. Imprint smears of both surgically resected and autopsy material showed two types of malignant neoplastic cells, of epithelial and mesenchymal origin.

[Case of pulmonary carcinosarcoma and a summary of 17 cases reported in Japan].

The patient was a 69-year-old man who complained of dyspnea and severe general fatigue. Chest CT showed a large tumor (6 x 5 cm) in the left S3 together with left pleural effusion. Despite pleurodesis and chemotherapy, he died 1.5 months after admission. At autopsy, a final diagnosis of pulmonary carcinosarcoma was obtained. We have summarized 17 cases of pulmonary carcinosarcoma reported in Japan. All patients were men, and had an average age of 68 years. The majority of the patients were heavy smokers. Death was reported in 70% of cases, the median survival period being 5 months, whereas the patients reported as living had operable cases of T2 tumor without distant metastatic lesions.

True malignant mixed tumor (carcinosarcoma) of parotid gland : a case report.

The malignant mixed tumor (carcinosarcoma) of the salivary gland is an extremely rare tumor. By definition, it is composed of both malignant epithelial and malignant mesenchymal components. We report a case of carcinosarcoma in the parotid gland of a 59 year old man, that arose "de novo" and contained ductal adenocarcinoma as the epithelial component and osteosarcoma and chondrosarcoma as mesenchymal components. The etiologic and histologic features are presented and in addition, the literature is reviewed.

Primary carcinosarcoma of the helix of the ear.

We report our histologic and immunohistochemical findings in a rare case of cutaneous carcinosarcoma involving the helix of the ear. The tumor exhibited cellular features of both basal cell and squamous cell carcinoma and a malignant mesenchymal component that was consistent with malignant fibrous histiocytoma. The epithelial component exhibited a positive immunohistochemical reaction to cytokeratin and a negative reaction to vimentin, whereas the mesenchymal component showed a positive immunohistochemical reaction to vimentin and a negative reaction to cytokeratin. To the best of our knowledge, this is only the third reported case of a carcinosarcoma of the ear and the second case in which it developed on the helix.

[Uterine carcinosarcoma in a teenager: report of a case macroscopically mimicking rhabdomyosarcoma].

Uterine carcinosarcoma (malignant mixed mullerian tumor) is uncommon. We report the case of a 17-year-old patient who complained of pelvic pain and abnormal genital bleeding, and had a voluminous hemorrhagic tumor protruding through the vaginal os. Hysterectomy was performed. The histopathologic and immunohistochemical evaluation led to the diagnosis of uterine carcinosarcoma. Adjuvant chemotherapy was given. In spite of the surgical treatment, the evolution was fatal with widespread metastases. From data of the literature, we discuss the diagnosis, histogenesis and treatment of this rare tumor.

Carcinosarcoma of the pancreas arising in a mucinous cystic neoplasm.

We report a carcinosarcoma of the pancreas in a 67-year-old woman who presented with nausea, vomiting, and painless jaundice. A work-up demonstrated a well-circumscribed mass in the head of the pancreas. After pylorus-preserving pancreaticoduodenectomy, the tumor was found to be grossly yellow, and it compressed the common bile duct and pancreatic duct. Histological examination of the neoplasm showed a 4.0 x 4.0 x 3.0-cm mucinous cystadenocarcinoma with invasive poorly differentiated carcinoma, well-differentiated squamous cell carcinoma, and sarcomatous stroma invading into the duodenum. There was no evidence of nodal metastasis (pT3N0M0). Immunohistochemical studies showed that the epithelial cells stained positive for cytokeratin 7, cytokeratin AE1/3, cytokeratin monoclonal antibody 5.2, epithelial membrane antigen, M-carcinoembryonic antigen, and low-molecular-weight kininogen, and the sarcomatous component was immunoreactive with vimentin. The patient had an uneventful recovery, but died 4 months later of rapidly progressive metastatic disease to the liver and peritoneum. To the best of our knowledge, this is the second case of carcinosarcoma with invasive epithelial and sarcomatous areas in the background of a mucinous cystic neoplasm of the pancreas.

Supracricoid partial laryngectomy as a primary treatment for carcinosarcoma of the larynx.

Carcinosarcoma of the larynx is uncommon. When it does occur; its clinical features resemble those of sarcomatoid carcinoma, and its biologic behavior is similar to that of malignant mesenchymal neoplasms. We describe 2 cases of carcinosarcoma of the glottis. The tumors were staged as T3N0M0 and T2N0M0. Both patients were treated with supracricoid partial laryngectomy with cricohyoidoepiglottopexy. Eight months postoperatively, 1 of the 2 patients experienced a recurrence of the sarcomatous component of the tumor, and he underwent a total laryngectomy. The other patient remained free of disease at 12 months of follow-up. We conclude that supracricoid partial laryngectomy may be offered as an organ-preserving measure even in patients with sarcomatous disease; total laryngectomy can be held in reserve as a rescue measure. Patients must be closely monitored for early detection of recurrence. The role of adjuvant therapy for sarcomatous neoplasms in this area has not yet been clearly established.

[A rare case of ovarian carcinosarcoma with metastasis in the uterine cervix--diagnostic and therapeutic problems].

Carcinosarcomas are rare malignant neoplasms that histologically contain both epithelial and mesenchymal components. In the female genital tract they occur mainly in uterus and rarely in cervix, ovaries and omentum. A rare case of ovarian carcinosarcoma is presented. Because of the presence of a solitary, massive metastasis in the uterine cervix, it created some serious diagnostic and therapeutic problems.

Post-irradiation carcinosarcoma of uterus--a case report.

The carcinosarcoma (malignant mixed mullerian tumour) of uterus is an aggressive neoplasm composing of malignant glands in the malignant stroma showing biphasic appearance. A 55 year old woman presented with discharge per vaginum of one month duration. Earlier she was given radiotherapy for squamous cell carcinoma of vulva, six years back. Abdominal examination was insignificant. USG suggested presence of post-radiation effect with uterine mass. Panhysterectomy was done and on histopathology, the diagnosis of carcinosarcoma (heterologous variant) was made. The case is being reported and discussed.

[Bladder carcinosarcoma with osteosarcomatous differentiation].

Osteoid tissue can eventually be identified outside the bone skeleton adopting the form of metastasis, osteoid metaplasia or primitive osteosarcoma. This latter presentation is most frequently located in soft tissues and exceptionally at the visceral level. The term used for any of these forms is extra-bone osteogenic sarcoma. This paper reports the case of a 62 year-old female patient diagnosed with vesical urothelial carcinosarcoma treated with external radiotherapy. After a disease-free period of 20 years the patient developed osteosarcomatous-differentiated vesical carcinosarcoma. A literature review is made to analyze, from a clinical and histopathological perspective, several items of interest presented by this pathology. The role of sarcomatous radio-induction is also highlighted. Finally, we emphasize the relevance of using radical treatments from the start, so as to restrain the highly malignant potential of this condition.

Polypoid adenosquamous carcinosarcoma of the epiglottis with blastomatous features.

A case is reported of polypoid adenosquamous carcinosarcoma with blastomatous features arising in the epiglottis. A 69-year-old man with hoarseness and sore throat was found to have a six cm pedunculated mass located on the epiglottis. Upon examination by light microscopy, it was found that the tumor was composed of not only well to poorly differentiated in situ and invasive squamous cell carcinoma but also adenocarcinoma with blastomatous features and a malignant primitive stroma, with features of undifferentiated sarcoma and focal chondrosarcomatous differentiation. To the best of our knowledge, this appears to be the second case of laryngeal adenosquamous carcinosarcoma with blastomatous features reported in the English literature and the third case in the world literature.

True malignant mixed tumor (carcinosarcoma) of palatal minor salivary gland origin.

True malignant mixed tumor (carcinosarcoma) of salivary gland origin is exceedingly rare and is distinguishable from the more frequently occurring carcinoma ex pleomorphic adenoma. This paper reports a case of true malignant mixed tumor originating from a palatal minor salivary gland of a 55-year-old male. Histologically, nests of poorly differentiated adenocarcinoma were scattered in a sarcomatous background which partially showed an unequivocal chondrosarcoma. Clinical course of the present patient suggested that a pre-existing benign minor salivary gland lesion developed to a carcinosarcoma.

[Bronchopulmonary carcinosarcomas. Therapeutic indications].

The authors make an analysis of 11 cases of carcinosarcoma that have underwent surgery in the Clinic of Thoracic Surgery. The authors stress the rarity of these cases in their statistics. Only 11 carcinosarcomas have been identified out of a total of 2.500 cases of bronchopulmonary tumors operated in the Clinic. The difficulty of pre-operatory diagnosis is also stressed. Indications for surgical treatment are mandatory in all cases, even when the expected effects are palliative.

[Carcinosarcoma of the urinary bladder and renal metastasis].

A 74 year-old woman developed a polypoid tumor of the bladder which was discovered by hematuria. Upon histological examination, the tumor was shown to be a carcinosarcoma with a weak epithelial composition confirmed by immunolabelling with keratin and was composed essentially of chondrosarcomatous material. Six months later, the patient developed metastases in the kidney, in the paravertebral muscles, and in the right para-ureteral lymph nodes. There are 55 cases of carcinosarcoma of the bladder described in the literature [3, 20, 22]. It is a tumor found more frequently in men than in women, between the ages of 33 to 83. The prognosis is very gloomy .70% death rate within 2 years), but it seems to be improved by radical cystectomy and adjuvant therapy.

[Demonstration of tumor inhibiting properties of a strongly immunostimulating low-molecular weight substance. Comparative studies with ifosfamide on the immuno-labile DS carcinosarcoma. Stimulation of the autoimmune activity for approx. 20 days by BA 1, a N-(2-cyanoethylene)-urea. Novel prophylactic possibilities].

A report is given on the recent discovery of outstanding immunological properties in BA 1 [N-(2-cyanoethylene)-urea] having a (low) molecular mass M = 111.104. Experiments in 214 DS carcinosarcoma bearing Wistar rats have shown that BA 1, at a dosage of only about 12 percent LD50 (150 mg kg) and negligible lethality (1.7 percent), results in a recovery rate of 40 percent without hyperglycemia and, in one test, of 80 percent with hyperglycemia. Under otherwise unchanged conditions the reference substance ifosfamide (IF) -- a further development of cyclophosphamide -- applied without hyperglycemia in its most efficient dosage of 47 percent LD50 (150 mg kg) brought about a recovery rate of 25 percent at a lethality of 18 percent. (Contrary to BA 1, 250-min hyperglycemia caused no further improvement of the recovery rate.) However this comparison is characterized by the fact that both substances exhibit two quite different (complementary) mechanisms of action. Leucocyte counts made after application of the said cancerostatics and dosages have shown a pronounced stimulation with BA 1 and with ifosfamide, the known suppression in the post-therapeutic interval usually found with standard cancerostatics. In combination with the cited plaque test for BA 1, blood pictures then allow conclusions on the immunity status. Since IF can be taken as one of the most efficient cancerostatics--there is no other chemotherapeutic known up to now that has a more significant effect on the DS carcinosarcoma in rats -- these findings are of special importance. Finally, the total amount of leucocytes and lymphocytes as well as their time behaviour was determined from the blood picture of tumour-free rats after i.v. application of BA 1. The thus obtained numerical values clearly show that further research work on the prophylactic use of this substance seems to be necessary and very promising.
