A metastasizing pleomorphic adenoma originating from the parotid gland is a rare form of neoplasm. The neoplasm is a histologically benign, but clinically controversial entity. Herein, a case report of a pleuro-pneumonectomy of a metastasizing pleomorphic adenoma in the right lung is described. A 57-year-old man, who underwent resection of parotid gland due to a pleomorphic adenoma, presented with multiple metastases on the right lung, mediastinum, pericardium and intercostal muscle. The metastatic lesions were composed of a benign pleomorphic structure.

Ipsilateral tonsillectomy and panendoscopy-guided biopsy following imaging studies are considered a standard procedure in the search for a primary origin in patients with cervical metastatic carcinoma of unknown origin(MUO). However, many authors recommended bilateral tonsillectomy for the determination of the primary site of a MUO, because cervical metastasis may occur contralateral to tonsillar carcinoma. The authors attempted to address the clinical implications of using routine bilateral tonsillectomy to determine the primary site of MUOs based on a case report of cervical MUO that was finally diagnosed as a bilateral synchronous tonsillar carcinoma with cervical metastasis after a diagnostic work-up that included bilateral tonsillectomy.

Purpose: The purpose of this study was to determine the utility of tumor marker CA 15-3 in the following: the diagnosis of breast cancer relapse after curative mastectomy, and the differentiation or the value of tumor marker by site of metastases. Materials and Methods: Two hundred two patients (median age 48 years) with breast cancer included in the follow-up after curative mastectomy. The tumor marker CA 15-3 was determined by IRMA (CIS BIO INTERNATIONAL, France). Test values > 30 U/ml were considered elevated (positive). Results: Among 202 patients, recurrent diseases were found in 16 patients. CA 15-3 was elevated in 5 of 16 patients with recurrences. There was no false-positive patient who had elevated CA 15-3. Sensitivity and specificity of CA 15-3 for detection of breast cancer recurrence were 31%, and 100%. CA 15-3 was elevated in all of the 4 patients with liver metastases. CA 15-3 was elevated in none of the patients who relapsed with metastasis to bone-only or contralateral breast-only. Conclusion: The tumor marker CA 15-3 in the detection of breast cancer relapse after curative mastectomy is specific, but not sensitive. However, it is useful to rule out liver metastases of breast cancer, which indicates bad prognosis.

Percutaneous transthoracic fine needle biopsy has been widely used In the diagnosis of pulmonary lesions especially lung cancer. Onc of the rarest complication's is that malignant cells are implanted within the needle tract and developed a chest wall mass subsequently. Wc expcrlenccd a case of chest wall implantatio of lung cancer after percutaneous transthoracic floe needle biopsy. A 65-ycar old man had undergone bilobectomy (right upper lobe and right middle lobe)for squamous cell (·4rcinoma (TINOMO) of the lung. 60 days after percutaneous biopsy (48 days after operation), a tiny nodule (1 mm sized) was notcd at the right anterior chcst wall where the diagnostic fine needle biopsy had been performed before operation. This tiny mass was rapidly growing to 1.5 cm sized mass for 20 days. We carried out wide excision of chest wall mass and skin grafting, and confirmed squamous cell carcinoma histopathologically as same as the lung cancer.

Ampulla of Vater (AOV) cancer is rare malignant tumor which arises within the vicinity of the AOV. Metastatic AOV adenocarcinoma has poor prognosis, with an overall survival rate at 2 years ranging from 5 to 10%. The Surveillance, Epidemiology and End Results Program of the National Cancer Institute indicated that lymph node metastasis was present in as many as half of patients which were associated with poor prognosis and liver was the second most common site of distant metastasis in AOV cancer. In this case report, we describe a case of complete resolution of AOV cancer, which was already spread to retroperitoneal lymph node and liver. The patient underwent gemcitabine plus cisplatin chemotherapy for palliative aim. After 12 month of chemotherapy, image study showed partial remission, so intraoperative radiofrequency ablation therapy and pylorus preserving pancreaticoduodenectomy was done. AOV cancer was completely resected and the patient was followed up without recurrence for 7 months.

Purpose: Because of the anatomical characteristics, it is difficult to perform radical operation in spinal tumor. Numerous operations on primary and metastatic spinal tumor have been performed and among those total en bloc spondylectomy has produced decent clinical result. Clinical and radiological results have been analyzed based on five total en bloc spondylectomy on primary and metastatic spinal tumor. Materials and Methods: Patients included in this study were one with primary and four with metastatic spinal tumors, from June 1997 to January 2006. Two of the four were originated form kidney. One was from breast and the other one was not identified. McAfee's 4 point scale, VAS and Frankel's classification have been used as clinical assessment of pain and neurological symptoms. Clinical assessment have been conducted for every 3 months after operation including local recurrence, bone union and complications. Results: Assessment of pain decreased from average of 3 before operation to 1.6 after operation in McAfee's scale and VAS decreased from average of 9.2 to 1.6. Neurological deficit after operation improved from C to D in Frankel's category. Local recurrence has been detected on metastatic adenocarcinoma of L4 during follow up. Conclusion: Total en bloc spondylectomy is evidently useful operational method for primary and metastatic spinal tumor since it completely decompresses spinal nerves, decreases axial pain immediately and improves the quality of remaining life.

Purpose: to know the treatment result of squamous cell carcinoma in extremity had poor prognosis with risk factor including burn scar and chronic osteomyelitis. Material and Methods: Between Octorber 1993 and September 2002, 20 patients with squamous cell carcinoma in extremity had no distant metastasis was got operation and followed over 36 months. Amputation was done when it was hard to get enough wide margin or neurovascular structure was involved instead of wide excision. Mean age of patients was 57.2 years old and male to female was 16 to 4. TMN staging and histologic grading were performed. Results: There were 6 metastasis (30%) in 20 cases for mean 48.3 months (36-84 months). 3 metastasis to local lymph node and 3 distant metastasis were happened at lung (in 3 cases) and thorasic vertebra (in 1 case). Survival was 18 cases at last look. 5-year survival rate was 50%. 3 local recurrence was developed at average 11 months (4-18 months). Complication was focal skin defect after wide excision and skin graft in 2 cases. The patients by wide excision got average 1.9 time operation and by amputation got average 1.3 time. Conclusion: Squamous cell carcinoma at extremity in Korea had high metastasis rate due to burn scar and chronic osteomyelitis, and it showed equal treatment result which treated by wide excision compared with amputation.

Endoscopic resection is one of the curative options for early gastric cancer. However, based on large-scale data about the risk of lymph node metastasis in early gastric cancer, endoscopic resection has been attempted for the following: differentiated intramucosal gastric cancer, regardless of size and without ulcers; differentiated intramucosal cancer, 30 mm in size with ulcers; minute submucosal differentiated cancer <30 mm in size; and undifferentiated intramucosal cancer, <20 mm in diameter without venous or lymphatic involvement. However, undifferentiated early gastric cancer exhibits different biologic behavior from differentiated early gastric cancer. Thus, the application of endoscopic resection for undifferentiated early gastric cancer remains controversial. In this review, we discuss the application of endoscopic resection for undifferentiated early gastric cancer based on analysis of biologic behavior and data of endoscopic resection.

Authors evaluated the accuracy of preoperative pelvic CT scan staging and its effects on management in 12 biopsy proved rectal cancer patients. Authors also studied postoperative CT in 5 patients to detect disease recurrence and metastasis. Preoperative CT staging was identical to surgical and/or pathological staging in 9 patients(75%), but it was underestimated in two cases and overstimated in one instance than in surgical stagings. In 7 cases, CT scan didnot alter original choice of procedures. However, preoperative CT staging gave definitive informations to change management plans in 5 cases otherwise the treatment would be difficult and inadequate. Postoperative CT showed local recurrence in one and liver metastases in 2 cases. One of them was not detected at exploratory laparotomy.

Surgical treatment of pelvic bone tumors represent one of the most complicated problem in musculoskeletal oncology. Because of three dimensional anatomy of the pelvis, tumors reach huge sizes and the diagnosed late relatively to a similar tumors in extremity. Especially, there are limited reconstruction methods to keep the function of hip joint after resection of periacetabular tumors, and the results of reconstruction is not so promissing. We present one case of periacetabular metastatic tumor from renal cell carcinoma, which was resected with wide margin and reconstructed with composite of pasteurized autogenous bone graft and constrained total hip arthroplasty.
