[Liposarcoma of the transverse mesocolon--a case report].

Primary mesenteric liposarcoma is a rare neoplasm. We experienced a case of liposarcoma of transverse mesocolon. In our case, the examination of ultrasonography and CT scan revealed the tumor was solid and encapsulated. Preoperatively we suspected the tumor was malignant by the angiographic findings. Laparotomy revealed that the tumor was located in the transverse mesocolon and it could be removed easily. The histopathological diagnosis was myxoid type liposarcoma. It is said generally that liposarcoma is liable to recur after simple resection, therefore, we reconsider that we should have excised more extensively for this case. The patient is doing well without evidence of recurrence for 17 months after operation.

[A case of mediastinal abscess due to Enterococcus faecalis accompanied with superior vena cava syndrome].

Superior vena cava (SVC) syndrome caused by benign diseases is rare. We reported a case of mediastinal abscess due to Enterococcus faecalis (E. faecalis) accompanied with SVC syndrome and reviewed the literature on this particular condition. A 38-year-old female with swelling of the neck and dilatation of cervical vein was admitted to our hospital, being diagnosed as having a SVC syndrome. Chest roentgenogram revealed an enlargement of the right upper mediastinum and a massive infiltration in the right upper lung field. CT scan demonstrated a mass with central necrosis occupying the right upper mediastinum and stenosis of superior vena cava. Further conformation of the stenosis of vena cava was made by means of venography. E. faecalis was recovered from the pus aspirated from the mediastinal abscess, and a definitive diagnosis of SVC syndrome caused by mediastinal abscess due to E. faecalis was made. There has been no report, to our knowledge, on mediastinal abscess evolving SVC syndrome in which E. faecalis was identified as a causative organism. The present case indicates that a benign disease such as lung abscess should be considered to be a possible cause of SVC syndrome in addition to other frequent malignant diseases.

Operative ultrasonography for lung cancer surgery.

During 60 operations for lung cancer, high-resolution (7.5 MHz) operative ultrasonography was performed to evaluate direct cardiovascular invasion of tumor (24 operations), lymph node metastasis (30 operations), liver metastasis (13 operations). Immediately after thoracotomy or sternotomy but before tissue dissection, operative scanning enabled delineation and evaluation of the evaluation of the vessels and heart (atrium) behind or within the tumor and detection of regional lymph nodes. The accuracy of operative ultrasound in diagnosing the presence or the extent of cardiovascular invasion was 91.7% (22 of 24 operations), which was significantly (p less than 0.02) higher than preoperative studies (62.5%), including computed tomography and angiography. Of the 24 surgical procedures, 23 were consistent with operations proposed on the basis of operative ultrasound findings, whereas only 16 were consistent with preoperatively proposed (p less than 0.01). Operative ultrasound provided the capability of depicting lymph nodes as small as 3 mm. More lymph nodes (8.0 +/- 1.84 nodes per cancer) were detected with operative ultrasound than with computed tomography (4.8 +/- 1.56 nodes) (p less than 0.001); however, the sensitivity and specificity of operative ultrasound in determining lymph node metastasis were 82.4% and 67.3%, respectively. No liver metastasis was identified. The information provided by operative ultrasound regarding cardiovascular invasion and lymph node and liver metastasis was considered helpful in selecting the type of surgical procedure an in avoiding unnecessary tissue dissection.

[A case report of thoracic duct cyst].

A case of mediastinal thoracic duct is described. A 27-year-old female patient was referred to our hospital for abnormal finding of her chest X-ray film, which revealed a mediastinal mass. CT scan, endoscopic ultrasonography, MRI showed that the mass was cystic in the posterior mediastinum. Intra operative ultrasonography demonstrated a thin-walled ovoid cyst containing some high echoic parts inside, which suggested condensed milky fluid. The small pedicle entered the upper pole of cyst was found at surgery and the cyst contained chyle about 300 ml. Histopathological specimen of resected cyst showed a structure of thoracic duct with some lymphoid tissue. Postoperative course was smooth. The characteristic finding of ultrasonography seemed to be valuable in the diagnosis of thoracic duct cyst.

[A case of squamous cell carcinoma of the breast].

A case of squamous cell breast carcinoma is presented. The patient was 31-year old woman with a complaint of a right breast mass. The tumor was found to measure 7.0 x 8.0 cm without any inflammatory signs, and was associated with a bloody nipple discharge. Lymph-node metastases of the ipsilateral axillary and supraclavicular nodes were noted, and metastasis to the fifth lumbar vertebrae also was seen. Because of a diagnosis graded T4bN3M1, stage IV, an extended radical mastectomy was performed. Histologically, the major portion of this tumor consisted of a squamous cell carcinoma with a minimal component of adenocarcinoma and accompanying keratinization. The patient died of this cancer 5 months after the operation.

Leiomyosarcoma of the breast--a case report and an electron microscopic study.

We treated a fifty six-year-old woman with leiomyosarcoma of the breast. Light microscopy showed typical findings of leiomyosarcoma and electron microscopy confirmed the smooth muscle origin of the tumor. The patient is well without evidence of metastases or local recurrence of the tumor fifty-five months after radical mastectomy.

[Effects of administration of an antineoplastic agent into the bronchial artery].

Morphological observation was performed to see the effect of bronchial arterial infusion therapy (BAI) of mitomycin C (MMC) and also of the ischemia to the transplanted bronchial carcinoma. Single shot of 2mg/kg of MMC showed destructive changes on the tumor. Single shot of 3mg/kg and repeated administration of MMC brought relatively severe intra-arterial inflammatory changes such as intimal edema, thickening and proliferation which suggested ischemic effect on the tumor due to poor perfusion from stenosis or obstruction of the vessels. On the other hand a simple ligation of the artery also brought about more than moderate destructive changes in the tumor. Therefore, mechanisms of the effect of the BAI of MMC to the lung tumor might involve the secondary effect from ischemia in addition to the effect of MMC itself.
