Spinal meningiomas located purely in the extradural space are rare, and they may easily be confused with malignant neoplasm. We report an unusual case of a purely extradural spinal meningioma mimcking metestatic neoplasm. A 38-year-old woman had neck pain and left side weakness. MRI scan revealed extradural spinal mass. Preoperative and intraoperative diagnosis was metastatic carcinoma, but permanent diagnosis was extradural meningioma.

A rotator cuff tear causes shoulder pain and limits movement of the shoulder joint. A chronic degenerative change or impingement is the reason for a rotator cuff tear. Diagnosis is made based on medical history and, physical and radiological examinations. Other causes of shoulder pain include calcific tendinitis, degenerative arthropathy, joint dislocation, fracture, and primary or metastatic neoplasm. However, metastatic cancer in the shoulder joint is difficult to diagnosis. We experienced a case in which a 46-year-old female patient complained of left shoulder pain and limited joint mobility, and these symptoms were due to metastatic breast cancer in the shoulder.

We report two cases of giant soft tissue sarcomas metastatic to the lung from lower extremities. The lung metastasis occurred 2 years later from original diagnosis in 27-year-old woman with hemangiopericytoma and 8 years later in 54-year-old woman with synovial sarcomtt. We had performed pleuropneumonectomies with partial resection of pericardium involved. The postoperative courses were uneventful and postoperative adjuvant therapy was begun.

The therapeutic results of pulmonary resection for metastatic bone and soft tissue sarcomas were analyzed. From 1986 to 1996, 14 patients(11 male and 3 female) underwent 15 pulmonary resections for metastatic sarcomas. One(7.1%) patient had 2 thoracotomies for recurrences. The number of metastatic tumors were from one to five. The primary malignant tumors were from bone in 4 and from soft tissues in 10. Mean survival time after thoracotomy was 29.2 months, and Kaplan-Meier's 5-year survival rate from the first metastasectomy was 33.2%. Three patients who had the tumor free interval period over 3 years were alive(mean survival period 52.6 months), whereas eleven patients of the less than 3 years were dead with disease(mean survival period 17.3 months). These results suggested that pulmonary. metastasectomy in bone and soft tissue sarcoma may prolong the survival rate.

Although neoplastic involvement of the pericardium is frequently present postmortem, cardiac manifestations before death are uncommon, and cardiac tamponade as the initial presentation of cancer is rare. We are presenting a metastatic pericardial tumor with cardiac tamponade of unknown primary neoplasm. The patient brought to hospital in a state of unconscious. The chest x-ray film showed cardiomegaly with a globular heart shape and right pleural effusion. We underwent an anterior thoracotomy and pericardial window was created. The histopathologic finding of pericardium, pleural and pericardial effusion show a metastatic adenocarcinoma. The patient subsequently received adjuvent radiotherapy and chemotherapy, but he expired on the postoperative 132 day.

Choroidal melanoma is the most common primary intraocular cancer in adults. The predominant sites of metastasis that are associated with a poor prognosis are liver, lung and bone. The authors report here on a case of metastatic choroidal melanoma in the rib and bronchus, and this was all treated by surgical resection.

Cytologlc evaluation of cerebrospinal fluid(CSF) is an effective mean for diagnosing many disorders involving the central nervous systems(CNS). One of the most important reasons for cytologic examination of CSF is to detect metastatic or primary neoplasms of the CNS. We did a retrospective study of 1,438 CSF specimens obtained between 1992 and 1996. A total of 1,205 adult and 233 pediatric CSF specimens from 947 patients were accessed at the Department of Pathology of Seoul National University Hospital and Children's Hospital, respectively. Among 1,438 CSF cytology specimens, 169 cases(11.8%, 77 patients) including 135 adult cases(59 patients) and 34 pediatric cases(18 patients) were positive for malignant cells. Diagnoses included 50 metastatic carcinomas(adult, 60; pediatric, 0); 46 malignant lymphomas(adult, 44; pediatric, 2); 21 leukemias(adult, 20; pediatric, 1); 4 retinoblastomas(adult, 0; pediatric 4); 2 rhabdomyosarcomas(adult, 0; pediatric, 2); 1 multiple myeloma(adult, 1; pediatric, 0), and 35 primary CNS neoplasms(adult, 10; pediatric, 25). The most commonly identified metastatic carcinomas in adults were adenocarcinoma. Their primary sites were the lung, gastrointestinal tract, and breast in order of frequency. The most common primary CNS neoplasm in children was medulloblastoma.

Renal cell carcinoma (RCC) represents 2% to 3% of human cancers and is aggressive, with metastatic capability. The frequent metastatic sites are lung, bone, and liver. Reports of RCC metastatic to skin, and especially scalp are rare. Here we present an 83-year-old woman who was diagnosed with RCC 19 years prior and had a metastatic scalp lesion. An 83-year-old woman presented with a red-to-purple, protruding lesion at the right parietotemporal area. Twenty-three years ago, a right renal mass was incidentally discovered on ultrasound through a routine medical examination. She underwent right nephrectomy for RCC 4 years later. Five months after nephrectomy, new lung nodules were observed. Fifteen years after nephrectomy, metastatic lesions were found in the pelvic bone. She visited dermatology department for evaluation of the new scalp lesion, a year before she first visited our department. Despite chemotherapy, the mass was gradually enlarged. She consulted the plastic surgery department for management of the metastatic RCC was successfully treated with total excision including a 1-cm safety margin, local flap, and STSG coverage. Complete healing was observed, without evidence of recurrence during a 7-month followup. Metastases to the skin are rare, but must be kept in mind because of its high metastatic ability and poor prognosis.

Cytologic diagnosis of the metastatic tumors to the thyroid is important in the management of the patients. There have been rare reports analyzing fine-needle aspiration (FNA) cytology of metastatic tumors to the thyroid. This study examines comprehensive cytologic findings of metastatic tumors to the thyroid with radiologic findings. The FNA cytology slides obtained from 12 cases with metastatic tumors of the thyroid; lung cancer (n=5), tongue and tonsil cancer (n=3), esophageal cancer (n=2), and breast cancer (n=2) were reviewed. Radiological study showed single mass with heterogeneous texture or multiple masses without calcification. Metastatic tumor was easily considered in a differential diagnosis of FNA cytology because they had peculiar cytological features which were not seen in primary thyroid tumor. The smear background varied from predominantly necrotic, bloody, and inflammatory to colloid. The aspirates exhibited a mixture of benign follicular cells and malignant cells in 6 cases. The characteristic cytoplasmic features of the tumor cells, such as keratin, mucin and melanin, were found in 9 cases. Although some cases mimic primary thyroid neoplasm, a careful examination of the cytological characteristics may help cytopathologists to recognize a metastatic tumor in the thyroid by FNA, and may help the clinicians to establish a proper treatment plan.

Metastatic tumors to the jaw bones are uncommon. The most common metastatic tumors to the jaw bones are the breast, lung and kidney. In the jaw bones, the common location of the lesions is the mandible, and the posterior area of the mandible is more commonly affected. The radiographic appearance is quite variable. In this report, a very rare case of metastatic gastric adenocarcinoma to the mandible is presented. The patient had undergone a gastrectomy 3 years ago.
