The case of a patient with uterine leiomyosarcoma is reported. Metastases to pre-existing cystic lung lesions resulted in spontaneous pneumothorax.

A 17-year-old woman underwent hysterectomy for removal of a "mitotically active" (six to seven mitoses per 10 high-power fields) yet otherwise benign-appearing cellular smooth muscle tumor. Eleven years later, she developed multiple histologically benign smooth muscle tumors in the posterior mediastinum, deep soft tissues of the neck, paravertebral region, incisional scar, and mesentery. The distribution and histologic appearance of the tumors, as well as the protracted clinical course, suggest multifocal origin rather than widespread metastases from a low-grade uterine leiomyosarcoma. This case raises the possibility that some similar cases reported as so-called benign metastasizing leiomyoma may be more satisfactorily explained by the concept of multifocality.

Because of its rare occurrence in the human, the endocrinologic and receptor-related aspects of an uterine leiomyosarcoma (LMS) are poorly understood when compared to what is known of, say, human endometrial cancer. Thus, to increase our understanding, we have succeeded, by the string method, in inducing an uterine LMS in the mouse and have studied the possibility of hormonal therapy as a method of treatment. The findings of our study are enumerated as follows: 1. The induced uterine LMS had an estrogen receptor, which was confirmed by a biochemical assay and, morphologically, by a PAP (the peroxidase anti-peroxidase technique); 2. The growth of this tumor was significantly inhibited by MPA (medroxyprogesterone acetate) therapy (100 mg/kg); 3. After MPA therapy, the estrogen receptor levels were increased, especially in the nucleus; and, 4. The growth of a secondary tumor, transplanted after the initial hormone therapy, was not inhibited by the readministration of MPA. Our results suggest that this experimentally-induced uterine LMS in the mouse provides a useful means to study therapeutic treatment, and may assist in furthering our understanding of human uterine LMS and lead to finding an effective therapy.

Seven cases of patients with gynecologic cancer and Sister Joseph's nodule, umbilical metastases from intraabdominal malignancy, are presented, making a total of 44 such cases in the literature. One such case, uterine leiomyosarcoma with umbilical metastases, is the first such lesion reported. Although the prognosis is generally poor, a few long-term survivors have been reported, and aggressive therapy may be warranted, particularly in patients with ovarian malignancy.

A case is reported of late cutaneous and muscular metastases of a uterine leiomyosarcoma following an initial simultaneous presentation with an endometrial adenocarcinoma. Such behaviour is discussed in view of the prognostic features of the original sarcoma.

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.

Three pulmonary resections were performed for two cases of metastatic lung tumor from uterine leiomyosarcoma. Case 1 was diagnosed as myoma uteri. Preoperative chest X-ray examination showed an abnormal shadow in the left upper lobe. Postoperative diagnosis was leiomyosarcoma. During radiotherapy for the pelvic lesion, the lung tumor was growing very rapidly and micrometastases were detected bilaterally without distant metastasis. Bilateral pulmonary resections were performed. Three months and 15 days later, second left pulmonary and thoracic wall resections were performed because of lung and pleural recurrence. Seven months after the first pulmonary operation, she died of systemic metastases. Case 2 was admitted to the hospital because of genital bleeding and diagnosed leiomyosarcoma of the uterus. The patient had a metastatic lung tumor in the left lower lobe preoperatively. Eighteen days after hysterectomy, left lower lobectomy was performed because progressive hemoptysis occurred for rapidly enlarged metastatic lesion. She died of intrapelvic bleeding three months after the operation without respiratory symptom. The prognosis of synchronously found out lung metastasis from uterine leiomyosarcoma is very poor. Neither chemotherapy nor radiotherapy is effective. Although it's difficult and controversial to decide the surgical indication, we need to operate on as soon as possible when there is no other distant metastasis. Even if the timing of operation is late, we can find the surgical significance of pulmonary resection for reduction of respiratory symptoms and probability of longer survival.

Four Chinese patients with extensive smooth muscle tumors of the inferior vena cava (IVC) and right heart are described. Two patients had primary IVC leiomyosarcomas and one had both IVC and cardiac metastases from uterine leiomyosarcoma. The remaining patient had extra-uterine intravenous leiomyomatosis, with extensive tumor calcification. Clinical presentation was variable, consisting of the Budd-Chiari syndrome, a new heart murmur, and signs of cerebral embolism. All the lesions were defined radiologically prior to surgical resection of cardiac tumors.

This study was undertaken to examine the incidence and conditions under which lymph node metastases are present and patterns of recurrence in women with uterine leiomyosarcoma (LMS) and endometrial stromal sarcoma (ESS), excluding malignant mixed mesodermal tumors. From 1981 through 1991, 21 women with LMS and 10 women with ESS were treated. Retroperitoneal lymph node dissections were performed in 15 women with LMS and 7 women with ESS. In the women with LMS, 4/15 (26.7%) had lymph node metastases; in each there was disseminated intra-abdominal disease. In the 7 women with ESS, there were no lymph node metastases present. Ten women (47%) with LMS developed recurrences, and 3 (14%) had persistent disease. In the 10 women with ESS, 3 (30%) had recurrences, and 1 (10%) had persistent disease. In total, recurrences involved the lung in 84% of cases. Of the 13 women with recurrences, 7 had undergone lymph node sampling, and all were negative; 4 additional women had no evidence of adenopathy on abdominal-pelvic CT scan. Lymph node metastases were found only with extrauterine disease, and in all of these cases there was rapid progression of the sarcoma. Women without extrauterine disease did not have lymph node metastases detected; however, there was still a high rate (40%) of distant failure. Knowledge of lymph node status had minimal impact on the clinical management of women with uterine LMS and ESS.

Thoracobiliary communications in the form of either pleurobiliary or bronchobiliary fistulas are reported complications of many diseases. A strong suspicion in the appropriate clinical setting is necessary to recognize this problem. Bilioptysis is the sine qua non of a bronchobiliary fistula. Diagnostic imaging studies are useful to identify the communication and to delineate its location. Although surgery is the optimal intervention, percutaneous drainage and intravenous antimicrobial therapy may offer the best therapeutic option in patients with metastatic cancer and limited physiologic reserve. We report a unique case of bronchobiliary fistula complicating a uterine leiomyosarcoma with hepatic metastases. Long-term palliation was achieved with percutaneous drainage and appropriate fluid and electrolyte replacement therapy.
