A series of 7748 leiomyomas of the whole body is presented. Ninety-five per cent of lesions occurrred in the female genital tract. Sixty-one of the remaining 371 were rejected because of inadequate histology or uncertainty as to exact site of origin. The 310 cases thus selected were analysed for
Smooth muscle tumors occur infrequently in the skin. They consist of a diverse group of lesions representing hamartomas as well as benign and malignant neoplasms. They may arise from arrector pili muscle, specialized smooth muscle of the genitalia, or vascular smooth muscle. Although rare, accurate
The ultrastructure of a series of primary and metastatic smooth muscle tumors is reviewed. Myofilaments and other smooth muscle features were present in all primary leiomyosarcomas of the soft tissues and uterus. They were also present but were less plentiful in most of the metastatic
Two cases of laryngeal smooth muscle tumours are reported: one a benign leiomyoma, the other a malignant leiomyosarcoma. These tumours may present diagnostic difficulties and immunocytochemistry is helpful in distinguishing smooth muscle tumours from other connective tissue neoplasms and spindle
Six cases of smooth muscle tumors of the stomach are reported. These comprise one leiomyosarcoma and five leiomyomas, observed over a period of five years. Clinical presentation, diagnosis difficulties and the method of treatment are discussed and the literature is reviewed.
The clinical and pathologic features of 60 smooth muscle tumors of the vagina were studied to determine the pathologic characteristics which best relate to clinical behavior and to define criteria for the diagnosis of leiomyosarcoma. Cellular atypism, mitotic activity, and tumor size and contour
Incidence of the benign and malignant tumors of smooth muscles of the alimentary tract is relatively low. Both kinds of tumors cause haemorrhage, which often urges a prompt surgical intervention. The paper deals with the problems encountered in diagnosis and treatment of 20 patients with the above
This paper presents an overview of smooth muscle tumors occurring in deep soft tissue. Although the existence of leiomyomas of soft tissue has been questioned in the past, it appears that they do exist but are rare, and must be diagnosed using stringent histologic criteria that include no atypia and
In retrospect, we analyzed 12 cases of gastric smooth muscle tumor, nine cases of leiomyomas and three of leiomyosarcomas. In only half the number of these patients was an adequate preoperative diagnosis made. Ulceration of the tumor apparently led to the misjudgment in some cases. Features more
A series of fifty-one smooth muscle tumors of the stomach seen at the Massachusetts General Hospital over a twenty year period is reviewed. Virtually all benign tumors were asymptomatic and were discovered in the course of autopsy or an unrelated operation. Malignant tumors frequently caused
The clinical and pathologic features of 32 smooth muscle tumors of the vulva were studied to determine the pathologic characteristics that best relate to the clinical behavior and to define criteria for separating leiomyomas from leiomyosarcomas. The length of follow-up ranged from 16 months to 20
We reviewed the records of 31 patients with smooth muscle tumors of the stomach seen at the First Surgical Department, Medical School, University of Athens, Greece, between the years 1961 and 1981 with special emphasis on the clinical data, diagnosis, and pathology. The majority of patients were
Twelve patients with oesophageal smooth muscle tumour were operated on between 1955 and 1984 in the Department of Thoracic and Cardiovascular Surgery of Helsinki University Central Hospital. Eleven tumours were leiomyomata, the twelfth was a leiomyosarcoma. Dysphagia (83%) and chest or epigastric
This report describes the echocardiographic appearance of an intrapericardial mass and pericardial effusion in an otherwise healthy patient. The tumor was a globular mass attached to the left atrium by a stalk, suggestive of a myxoma. The mass was successfully excised and the patient had an
Five smooth muscle tumours presenting as pleural neoplasma are presented. The patients were three women and two men aged between 21 and 69 years (mean = 45 years). Clinically, one patient presented with chest pain, one with empyema and the other three were asymptomatic. Two of the tumours were
