Chondrosarcoma is one of the most common types of primary bone sarcoma. With the exception of the mesenchymal subtype, chondrosarcomas are usually low-grade lesions and rarely show multicentricity or distant metastasis. Only rare cases of multicentric chondrosarcomas have been reported in association with Ollier's disease and Maffucci's syndrome. To our knowledge, no report has been issued of a synchronous multicentric chondrosarcoma occurrence across a joint. We experienced a 30-year-old man with a synchronous monomelic juxta-articular multicentric chondrosarcoma across a shoulder joint in the absence of pulmonary and visceral metastases. He was treated by curettage and cement filling with allograft in the acromion and wedge resection with cement filling in the proximal humerus. At the 18-month follow-up, there was no evidence of recurrence, and the patient had full range of motion without pain.

Bronchogenic cyst is rare lesion that arises from maldevelopment of the primitive foregut, and is usually found in the lung and mediastinum. Cutaneous or subcutaneous bronchogenic cyst is rare and occur unusually in the shoulder region. We report here a case of 20-month-old boy with a bronchogenic cyst on his left shoulder region. He underwent incisional biopsy and curettage for a tender cystic mass at a department of dermatology, diagnosed as a epidermal inculsion cyst. But, additional cystic mass was palpated during wound care. MRI showed a well-defined subcutaneous cystic mass. The excised cyst was lined with pseudostratified ciliated columnar epithelium with occasional goblet cells and diagnosed as a bronchogenic cyst.

Bronchogenic cysts are usually located in the pulmonary parenchyma or mediastinum. When they are located in the mediastinum, they are usually near the bronchus or esophagus, but they are rarely at an intramural location of the esophagus. It is very difficult to differentiate between bronchogenic cyst and esophageal cyst before the operation. We report here on a patient for whom the preoperative diagnosis was supposed to be an esophageal cyst. The esophageal cyst was excised through the longitudinal division of the esophageal muscular layer without injury of the mucosa after right thoracotomy. The pathologic report revealed intramural bronchogenic cyst. We report here of a case of bronchogenic cyst that was located in the muscle layer of the lower esophagus.

Intracranial involvement by adenoid cystic carcinoma (ACC) is very rare and there is no report of intracranial extension from the palate ACC in Korea. Intracranial involvement can occur in one of three ways: direct extension, perineural spread, and hematogenous spread. A case report of a 35-year-old woman with intracranial ACC is presented. Initially she had ACC of the right palate and was treated by surgery and postoperative radiation therapy. Three years and 10 months later, the paresthesia in the distribution of ophthalmic and maxillary branch of right trigeminal none developed without evidence of recurrence in CT scan. Ptosis and total ophthalmoplegia developed sequentially and the second operation was peformed. It was suggested that the tumor was spread perineurally along the trigeminal news into the Gasserian ganglion and then cavernous sinus and orbit. Seven years and 6 months after the first operation, direct intracranial extension into the right temporal lobe developed via sphenoid bone, sphenoid sinus and temporal bone and the third operation was done. And then lung metastasis was diagnosed. She is alive for 9 years 5 months after first operation.

Pulmonary tuberculomas show variable responses to treatment, with some even increasing in size after treatment. To date, however, no data have been reported on the response of tumorous type of endobronchial tuberculosis (EBTB-T) to treatment observed both bronchoscopically and histologically. We report a case of bacteriologically- and biopsy-proven EBTB-T that showed delayed response to anti-tuberculosis treatment. Even after EBTB-T was treated with antituberculosis drugs for 15 months, the bronchoscopic findings and the histologic findings of chronic granulomatous inflammation with caseation necrosis still remained. However, in fourteen months after the completion of treatment, the lesioneventually disappeared without further treatment.

"Middle lobe syndrome" which was described y Graham and associates at first is always caused by ex- ternal bronchial compression by Iymph nodes. Although the patients may not present any symptom, the most common presenting symptoms were cough, dyspnea, fever, hemoptysis, and chest pain. Diagnostic procedures includ chest X-ray bronchoscopy, brochography, chest CT, and the principal finding is the contracted middle lobe which is usually airless. We experienced fifteen cases of middle lobe syndrome from April 1990 to May 1995. Eleven patients were treated surgically. The surgical candidates for middle lobe syndrome are suspicious malignancy, fixed bronchiectasis, bronchostenosis, intractable to medical treatment, recurrent infection. Operations were right middle lobectomy (8), right middle and lower bilobectomy (2), right upper and middle bilobectomy (1). Postoperative histological findings were tuberculosis in six, chronic inflammation in three, malignancy in one, and focal hemorrhage in one. There were two cases of postoperat ve complications which were postoperative atelectasis and hepatopathy.patopathy.

Mediastinal lipoblastoma is a rare benign tumor originating from embryonic lipid cells and it almost always occurs during infanthood or early childhood. It is a tumor with a good prognosis despite its potential for local invasion and rapid growth. We report here on a three years old girl who was treated for a benign lipoblastoma in the anterior mediastinum. CT scanning showed a fat containing mass without internal calcification or fluid component, and the mass showed a compressive effect on the adjacent structures. The mass was located between the pericardium and right mediastinal pleura and it was removed completely without complication. Pathologic examination revealed a benign lipoblastoma. The patient showed no evidence of recurrence at the time of the report.

A 12-year-old female mixed breed dog receiving a progesterone drug was referred for evaluation of an abdominal mass. Abdominal radiography and ultrasonography revealed a swollen uterus and an associated mass. Serum chemistry revealed hyperglobulinemia consistent with acute inflammation based on the results of serum protein electrophoresis. Fine needle aspiration of the mass guided by ultrasonography was performed for cytological evaluation. The cytological impression was consistent with adenocarcinoma. Exploratory laparotomy identified a uterine body mass, which was surgically removed for histopathology. Histology of the mass identified a uterine adenocarcinoma. Immunochemistry using anti-estrogen and progesterone receptor antibodies was performed and neoplastic cells were negative to both antibodies while some normal elements were reactive to both of them. Computer tomography demonstrated evidence of metastatic disease in the lung one week after the surgery and the dog died about 40 days after surgery.

Inflammatory pseudotumor, also known as plasma cell granuloma, is a rare, benign tumor that affects at all ages and frequently involves the lung, gastrointestinal tract, and salivary gland. They are the most common, isolated, primary lesion of the lung in children less than 16 years of age, and usually present as circumscribed, peripheral, parenchymal tumors, which may be static or increase slowly in size without causing symptoms. Surgical excision is the treatment of choice bacause of the location and benign nature of this lesion. The prognosis after resection is excellent. Adjuvant therapeutic modalities include radiation and steroid therapy. Recently, we experienced a case of inflammatory pseudotumor of the lung, the diagnosis of which was made by percutaneous fine needle aspiration cytology examination. We tried steroid and the lesions of the lung was completely resolved. We report this case with a review of literatures.

Endobronchial chondroma is a cartilaginous benign tumor, which arises from bronchial cartilage. As a rare benign tumor, endobronchial chondroma differs from cartilaginous hamartoma in that it includes cartilage components only, but hamartoma contains lipomatous and lymphoid tissue. The clinical manifestations of endobronchial chondroma are associated with the extent of mechanical obstruction of bronchus. Symptoms of endobronchial chondroma are nonspecific, such as cough, sputum, fever, or dyspnea on exertion. Endobronchial chondroma is often misdiagnosed as other diseases, such as asthma, chronic obstructive pulmonary disease, or pulmonary tuberculosis. The treatment is usually surgical procedures, such as resection of lung segment or lobe by thoracostomy, or resection of tumor by bronchoscopy. We report a case of the patient who was diagnosed to have endobronchial chondroma treated by bronchial resection and end to end anastomosis.
