Sarcomas of the prostate are rare tumors and are predominantly rhabdomyosarcoma in children and
leiomyosarcoma
in the young adult (less than 50 years). We report on a rare case of prostate sarcoma in a 49-year-old patient whose presenting features were those of rapidly evolving prostatism and dyschezia (rectal constipation). The diagnosis was established histopathologically by cytology and biopsy. Despite the initial chemotherapeutic treatment, the course of the disease was fulminant and the patient died from multiple lymphatic
metastases
. We discuss its embryonal origin, clinical features, differential diagnosis and underscore the need for sequential combined treatment with chemotherapy, surgery and post-operative radiotherapy.

Two-dimensional echocardiography was used to study malignant metastatic neoplasms of the heart and great vessels in 20 patients, 13 males and seven females, whose ages ranged from 15 to 72 years. Five patients had lung cancer; two each had breast cancer, malignant melanoma, hepatoma and one each had gastric cancer, urinary bladder cancer, adrenocortical carcinoma, malignant lymphoma, angiosarcoma, fibrosarcoma,
leiomyosarcoma
; and two had cancers with unknown primaries. Tumor invasion was demonstrated echocardiographically in the left atrium in one each with breast cancer, fibrosarcoma and gastric cancer; in the right atrium in two with hepatomas; in the right atrium and right ventricle in one patient with adrenocortical carcinoma; in the left ventricle in one with lung cancer; and in the pulmonary artery in one with malignant melanoma. Massive pericardial effusion was observed in 11 of 20 patients; two with pericardial tumors including malignant lymphoma and lung cancer. We conjectured that metastatic tumors in the right cardiac cavities came through the inferior vena cava, and other tumors in the left atrium, left ventricle and pericardium developed from direct extension of the primary lesions. There was an 80% mortality of the patients during the observation period, and the average survival period after the diagnosis of cardiac
metastases
was 5.5 months. However, one patient was still living after two years of radiation therapy and chemotherapy. Echocardiography proved a useful, non-invasive means for the detection and follow-up observation of metastatic cardiac tumors.

Primary sarcomas of the kidney in adults are rare. In the handful of published reports of all soft tissue sarcomas, DNA ploidy has correlated with histologic grade and outcome. This report presents the clinicopathologic and flow cytometric features of 17 cases of primary renal sarcoma (seven men and ten women, ages 28-69 years). Presenting symptoms included abdominal and back pain and hematuria. Stages at diagnosis were I, in three patients; II, five patients; III, two patients; and IV, two patients. Eight tumors were
leiomyosarcoma
, two malignant fibrous histiocytoma, one hemangiopericytoma, one fibrosarcoma, and five unclassified. Tumors measured 5.5 to 23 cm, seven contained marked nuclear pleomorphism, seven were extensively necrotic, and mitotic rate was 1 to 33 per 10 high-power fields. Seven tumors showed aneuploidy and five were diploid. Thirteen patients were dead of disease after a mean of 23 months and two were alive with known
metastases
at 29 and 33 months, respectively. Ploidy pattern and outcome or time to death were not correlated, but aneuploidy correlated with histologic grade, marked nuclear pleomorphism (P less than 0.05), extensive necrosis (p less than 0.01), and high mitotic rate (0.05 less than P less than 0.10). The authors conclude that although DNA ploidy does correlate with histologic grade, for primary renal sarcomas, whose prognosis in this series was extremely poor, it does not correlate with outcome.

Neoplastic cavitary lesions are an unusual type of pulmonary
metastases
. The authors report two cases of cystic metastatic sarcoma of the lungs that illustrate the clinical, radiologic, and pathologic difficulties encountered in the diagnosis of these lesions. In one patient, multiple small, thin-walled cystic
metastases
from a lower leg
leiomyosarcoma
were the only manifestation of
metastatic disease
. The cystic lesions did not change over an 8-month period and a diagnosis of malignancy was not established until spontaneous pneumothorax, presumably due to rupture of the malignant blebs, prompted a thoracotomy. In the second patient, three thin-walled bullae developed after treatment of noncystic pulmonary
metastases
from a lower-leg synovial sarcoma. In both patients, the cystic lesions were not evident on chest radiographs, but were well visualized with computed tomography (CT), where they mimicked benign bullous disease. However, additional small cavitary lesions not seen with CT were present in resected pulmonary wedge specimens from both patients. A great degree of variability in the cellular composition of the cyst wall lining in both cases, and a lack of any solid neoplastic tissue masses in one case, led to histopathologic difficulties that required immunohistochemical studies for definitive diagnosis of the
metastatic disease
. These cases show that pulmonary bullae, even though thin-walled and benign-appearing on CT, may be a manifestation of pulmonary
metastases
. These lesions must therefore be surgically removed from patients in whom a curative resection of pulmonary
metastases
is warranted.

The 11th case of primary
leiomyosarcoma
of the renal vein is reported. Unique features of this case included concomitant resection of an isolated hepatic metastasis, intraoperative radiation therapy, and the use of electron microscopy and immunohistochemical stains in confirming the diagnosis. A review of the previously reported cases shows a tendency toward slow tumor growth and infrequent recurrence (18%).
Metastases
are common (82%), primarily to the lung and liver. Aggressive surgical resection and adjuvant radiation therapy, including intraoperative radiation therapy, are recommended. Adjuvant chemotherapy should be considered, although its benefits at present are unclear.

During 25 years, 708 patients with primary malignant tumours of the thoracic oesophagus (n = 376) or cardia (n = 332) were referred to our department. Two hundred and forty-nine patients had squamous cell carcinoma and 425 adenocarcinoma. The other 34 tumours, which were primarily classified as undifferentiated carcinoma, malignant carcinoid or non-epithelial, were re-evaluated by means of a second microscopic histologic examination and immunohistologic investigation. This showed primary malignant non-epithelial tumours in seven patients (0.99%): two malignant melanomas, one
leiomyosarcoma
, one malignant fibrous histiocytoma in the oesophagus (1.06%), two malignant lymphomas, and one malignant melanoma in the cardia (0.90%). All but two of the patients with non-epithelial malignant tumours were 67 years of age or older, and oesophagogastrectomy was performed in all. All tumours were 5 cm or more in diameter (median, 8 cm). Distant
metastases
were found in three cases. Five died of postoperative complications, one of cancer recurrence 7 months after the operation, and one of an unrelated cause without cancer recurrence 16 months postoperatively. Except for two of the melanomas, the diagnosis was not established until histologic examination of the surgical specimen was performed and, for the third melanoma and the malignant fibrous histiocytoma, not until the present re-evaluation. The characteristics of these seven tumours are discussed, and the importance of obtaining a correct diagnosis from endoscopic biopsy specimens is emphasized.

Primary leiomyosarcoma of the pancreas is a very rare malignant tumor, with only 12 cases reported. A case of primary pancreatic
leiomyosarcoma
in a 55 year-old female with diabetes mellitus is described. US and CT demonstrated tumor masses in the head and tail of the pancreas. By angiography, abundant tumor vessels corresponding to the pancreatic tumor masses were revealed in the pancreas. The patient underwent surgical resection of the tumor in the tail of the pancreas, and then, microscopically it was diagnosed as
leiomyosarcoma
. The tumor in the head of the pancreas was not resected on account of the presence of diabetes mellitus and the possibility of poor prognosis. Macroscopically, it seemed to be the same as the tumor in the pancreatic tail. By operative findings, there was invasion from the pancreatic head to the duodenum and there was nothing to justify suspicion of the extra-ductal growing type of primary
leiomyosarcoma
of the duodenum. There were no
metastases
noted at the time.

The paper describes a cases of jejunal
leiomyosarcoma
associated with severe enterorrhagia. The rarity of this lesion and its difficult diagnosis are underlined. Having discussed the different anatomo-pathological aspects, the most appropriate diagnostic methods for a early diagnosis are examined. Moreover, the utility of carrying out a regular clinical and diagnostic follow-up of patients who have undergone surgery is stressed so that possible relapses or
metastases
, which are fatal in the majority of subjects affected by this form of neoplasia, can be treated as quickly as possible.

A case of five-year survival of jejunal
leiomyosarcoma
with
metastases
to the liver and mesentery treated with four times surgery was reported here. Four metastatic lesions were detected in the sigmoid mesocolon once and in the liver three times and resected with hope of cure. The patient, a 37 years old male, tolerated surgical procedures including an extended right hepatic lobectomy and recovered each time. He is leading a satisfactory daily life 5 years and 3 months after the initial operation although multiple liver metastases were detected 10 months after the fourth operation. A positive surgical therapy is advocated in selected patients who have spreading
leiomyosarcoma
of the bowel.

We present the fatal case of a patient with a primary
leiomyosarcoma
of the pulmonary trunk. During the patient's clinical course of 2 months, the pulmonary valve and the proximal segment of the truncus pulmonalis had to be removed surgically. At autopsy, we found an extensive local tumour recurrence with an almost complete obliteration of the right ventricular outflow. The right pulmonary artery was subtotally obliterated by a tumour thrombus, and the lungs and both adrenal glands showed extensive tumour
metastases
. A solitary tumour metastasis within the lumen of the right vena iliaca communis obviously was associated with diagnostic manipulations in the course of heart catheterization.
