Intravenous leiomyomatosis of the uterus is a rare tumor that presents with benign histological features. It is characterized by intravenous proliferation of smooth muscle cells originating from the uterus that sometimes extends to the inferior vena cava and the right heart. It may spread elsewhere, usually to the lung. The first case of intravenous leiomyomatosis was described in 1896 by Birsh-Hirshfeld, and only a few cases have been reported since then. Its pathogenesis and optimal treatment have not yet been established. We report a case of metastasizing leiomyomatosis found to have multiple nodular densities in both lower lung fields seven months after myomectomy. In another case the leiomyomatosis was confined to the pelvis after a laparoscopy assisted vaginal hysterectomy, the patient is alive without evidence of disease. Here we provide a detailed report of two cases of intravenous leiomyomatosis of the uterus with a brief review of the literature.

Primary benign tracheal tumors are exceedingly rare and leiomyoma has the least frequency among them. It is important to recognize early without misdiagnosis such as asthma because it is curable. A 41 year-old female was admitted for dyspnea and choking since November 1991. Under the impression of asthma, she received medication. Symptom was not improved and thus chest CT scan was performed. There was endotracheal tumor mass which was located just above the carina and arose from the right lateral tracheal wall with broad base. We successfully resected the tumor mass including trachea and the defected area of trachea was reconstructed with autologous graft using pericrdium & rib cartilage. During the follow up period, no complication was developed.

미주신경의 마디신경절내에 존재하는 신경세포는 경부, 흉강 및 복강의 감각신경을 지배하는 것으로 알려져 있으며 이와 관련된 SP, CGRP 등의 신경펩디드의 분포에 관하여 많은 보고가 이루어졌다. Vasoactive Intestinal Peptide(VIP)는 혈관, 평활근, 분비선 주위에 분포하는 부교감신경세포의 전달물질로서 후두의 자율신경계의 조절에 중요한 역할을 하고 있다 이러한 VIP지배신경의 기원에 관해서는 미주신경이나 후두신경, 그리고 일부 후두 구조내에 존재하는 부신경절(Paraganglia)에서 기원한 후 신경절 부교감신경으로 알려져 있는데, 즉 미주신경의 마디신경절은 단지 감각신경의 기원이 되는 신경세포 집합체로 마디신경절과 자율신경계의 상관관계에 대한 연구는 극히 드문 실정이다. 그러나 일부 보고에서 성문하부의 점막상피에서 SP나 CGRP외에도 VIP 양성세포가 발견됨으로써 일반적으로 자율신경계 세포로 알려진 VIP 양성세포의 기원과 기능은 더 규명되어야 할 부분의 하나로 사료된다 금번 저자는 고양이의 마디신경절에 대하여 면역 조직화학적 방법을 통한 VIP양성 세포의 출현여부를 관찰함으로써 마디신경절과 자율신경계와의 상관관계를 알아보고자 하였다.

We describe the case of a 58-year-old woman who has coexisting intrapulmonary and mediastinal leiomyomas. Initially, she was seen with a single mass in the right lower hilar area in a simple chest roentgenogram. But computed tomography demonstrated another mass in the right posterior mediastinum. Microscopic examination and immunohistochemical staining of the resected specimens showed the characteristics of the leiomyoma.

The coexistence of mesenchymal tumor and carcinoma in the esophagus is extremely rare. We report a case of squamous cell carcinoma located at the mucosal surface over leiomyoma of the esophagus. A 76-year-old man with complaints of 3 months onset of odynophagia was diagnosed preoperatively as squamous cell carcinoma over submucosal tumor with calcification. Esophagectomy and esophagogastrostomy were performed through the right thoracotomy and upper median laparotomy. The patient is doing well without evidence of recurrence in the 25 months after resection. We discuss the pathogenesis and possible relations between the two tumors.

We report here a case of pulmonary benign metastasizing leiomyoma from the uterus in a 45 year old woman. The patient presented for investigation of multiple pulmonary nodules on a routine chest roentgenogram. The patient had undergone uterine myomectomy due to uterine leiomyoma 10 years earlier. We performed thoracoscopic wedge resection for definitive diagnosis. Histologically, spindle shaped smooth muscle cells appeared between collagen stroma, histology similar to that seen in uterine myoma. The tumor tissue tested positive for estrogen and progesterone receptors. The pathological findings were consistent with benign metastasizing leiomyoma. The patient was in pre-menopause. She received no specific treatment for lung tumors, and we did not found any changes in the lesions after one year follow up without any medication.

A 42-year-old female was admitted to our hospital complaining of a dyspnea. Chest X-ray showed left atelectasis. A mass was detected in left main bronchus by computed tomography and bronchoscopy. The mass was diagnosed as a endobronchial leiomyoma by biopsy exam. After open thoracotomy and bronchotomy, mass removal was done and middle lobe was ventilated normally. Aberrant arterial supply from descending aorta to left lower lobe of the lung was detected and left lower lobectomy was done. The lower lobe of the left lung was pathologically diagnosed as intralobar pulmonary sequestration. Herein we report a rare coexistent case of endobronchial leiomyoma and intralobar pulmonary sequestration.

A 46-year-old man who had been diagnosed with esophageal tumor by PET-CT was admitted to our hospital for operation. Preoperative examination and intraoperative findings showed leiomyoma-like lesion and enucleation was done, but an immunohistochemical test on the case found gastrointestinal stromal tumor (GISTs). GISTs are very rarely found in the esophagus. As GISTs differ from leiomyoma pathogenetically and clinically, different treatments and follow-up strategies are required. The patient is under continuous observation to check recurrence and metastasis.

A 12-year-old neutered male Shih Tzu presented with constipation and dyschezia. Abdominal radiographs showed distension of the descending colon and dorsal compression of the colon by a soft tissue mass. The mass was well-marginated with homogeneous soft tissue attenuation and showed no evidence of metastasis on computed tomography (CT). The dynamic CT showed a consistently mild contrast enhancement. The perfusion and capillary permeability were lower than those of the gluteal muscle. The tentative imaging diagnosis was a benign intrapelvic tumor, which rarely shows angiogenesis. The mass was excised, and a leiomyoma was confirmed by histopathologic examination.

Background: Using the neovascularizing properties of the omentum, we studied the viability and vascularity of the cryopreserved rat tracheal allografts with omental implantation. Material and Method: The cryopreserved tracheal allografts of eight-week old male Sprague Dawley rats were implanted into the omentum. The rats were divided into the four groups according to the duration of cryopreservation and of omental implantation. We examined the tracheal allografts histologically for viability of cartilages, inflammation and fibrosis of smooth muscle and connective tissue, and degree of vascularity. Result: The degree of inflammation in the smooth muscle and the connective tissue of the tracheal allografts was not statistically related to neither the duration of cryopreservation or of omental implantation. The tracheal cartilages of the tracheal allografts were found to be severely calcified in all cases. Significant difference in vascularity was found between the groups I and II (p < 0.05). And a sufficient vascularity in the intercartilaginous space was observed in the mid portion of the tracheal allografts as well as both ends. Conclusion: In conclusion, the omental implantation for 2 weeks could establish a sufficient vascularity in the intercartilaginous spaces for maintaining the viability of the tracheal allografts. This study might provide a possibility of the sequential tracheal allotransplantation after omental implantation.
