1271/1723. Calcified gastric leiomyoma--a case report. A 62 year-old man was admitted with the chief complaint of a epigastric pain and difficulty of swallowing. Examination of the upper gastrointestinal tract revealed a calcified mass causing a smooth filling defect at the lesser curvature of the cardia. At laparotomy, a localized tumor was detected beneath the serosa of the stomach. The excised tumor was 4 x 4 x 1.6 cm and the pathological diagnosis was calcified leiomyoma probably due to cytoplasmic degeneration. In this paper, details of the case are described and the related literature is reviewed. ( info) |
1272/1723. association of gastric leiomyoma and leiomyoblastoma. The authors report a case of a male 53 years old with a leiomyoma and a leiomyoblastoma in his stomach. The signs of clinical presentation were given by the leiomyoma. The leiomyoblastoma was a surgical finding. The rarity of the association of these two lesions and the malignant potentiality of them are reviewed, according to the previous literature. ( info) |
1273/1723. Multiple pulmonary (hamartomatous?) leiomyomas. light and electron microscopic study. The light and electron microscopical features of the lung tumors in a case of multiple pulmonary leiomyomas are described. The differential diagnosis of leiomyomatous tumors of the lung is discussed. They have to be differentiated from lymphangio-leiomyomatosis of the lungs. In the literature, multiple pulmonary leiomyomas are generally considered to be metastases from low grade uterine leiomyosarcoma or to be hamartomatous lung tumors. This is suggested by the glandular structures both within the tumor and on the surface. However, our ultrastructural observations showed these epithelia to have features of granular pneumocytes (type II), in particular they contain lamellar bodies and possess microvilli on their surface. Their formation is considered to be a secondary reaction of alveolar lining cells to tumor growth. A possible origin of multiple pulmonary leiomyomas from the contractile system of the lung acini (contractile interstitial cells) is discussed. ( info) |
| A case of leiomyomatosis peritonealis disseminata (LPD) is presented with the unique finding of occasional endometrial glands and stroma within smooth muscle nodules. The possible origins of this tissue are discussed in relation to the histogenesis and prognosis of LPD. ( info) |
1275/1723. leiomyomatosis peritonealis disseminata associated with pregnancy. The first reported case in the English literature involving leiomyomatosis peritonealis disseminata (LPD) and a subsequent pregnancy is presented. A review of the literature revealed only 8 previous cases-all of which were treated by tubal ligation or surgical castration. The patient in this report was 22 years of age at the time of diagnosis, the youngest age at which LPD is known to have occurred. The LPD was first noted at primary cesarean section, and 20 months later at a second cesarean section performed at 35 1/2 weeks' gestation, the LPD had advanced to a stage that suggested possible malignancy. All biopsy specimens were subsequently reported as benign LPD. ( info) |
1276/1723. ultrasonography of rapidly growing uterine leiomyomata associated with anovulatory cycles. Three cases of rapidly growing leiomyomata uteri in young oligomenorrheic women are presented. The atypical ultrasonic and histologic findings are discussed. A spectrum of atypical ultrasonic findings including a high degree of transonicity and multiple areas of cystic degeneration is described. Histologic examination correlates well in explaining the sonographic characteristics. In addition, a possible relationship between the presumably anovulatory cycles present in these women and their rapidly growing leiomyomata is suggested. ( info) |
1277/1723. Atypical leiomyoma of prostate. A prostatic leiomyoma with nuclear atypia, similar in appearance to atypia sometimes seen in uterine leiomyomas, was an incidental finding in a fifty-three-year-old man who underwent prostatectomy for hyperplasia. The smooth muscle nature of the lesion was confirmed by electron microscopic examination. This is the third lesion of this type to be reported. ( info) |
1278/1723. Haemangioleiomyomatous tumour of the lung. A case of haemangioleiomyomatous tumour of the lung, occurring as a peripheral, solitary nodule in an asymptomatic 54-year-old man is presented. The tumour was well-demarcated and microscopically it was characterised by the presence of vascular spaces with endothelial, pericytic, and, predominantly, smooth muscle proliferation. islands of cartilage and slit-like spaces lined by bronchial epithelium make this a hamartomatous lesion of a quite distinctive and unusual variety, which does not fit any of the well-recognised patterns of hamartomas previously described. The long-term prognosis after limited excision is considered to be favourable. ( info) |
1279/1723. leiomyomatosis peritonealis disseminata. The ninth documented case of leiomyomatosis peritonealis disseminata (LPD) combined with pregnancy is presented. light and electron microscopic studies revealed that the smaller tumors were composed partly of decidual cells and partly of fibroblasts, and the larger tumors contained cells resembling smooth muscle cells. plasma steroid levels were determined during pregnancy. Estrogen levels were within normal range, but progesterone levels were lower than normal, resulting in relative hyperestrogenism. In the case presented, pregnancy, especially with relative hyperestrogenism, may have been a major cause of LPD. ( info) |
1280/1723. Calcification in childhood leiomyoma. Leiomyoma is a benign, smooth-muscle tumor which rarely affects children. Calcification in this tumor is unusual. Two boys, aged three and six years, had large axillary leiomyomas with "mulberry" calcifications similar to those seen in calcified uterine leiomyoma. The lesions did not recur after total surgical excision. ( info) |
