Lipomatosis is a condition containing multiple lipomatous masses.Lipoma is a benign neoplasm composed of adult adipose tissue, and occur most often in the fifth or sixth decade and rarely in the pleura. Pleural lipomas are usually asymptomatic and revealed as an incidental roentgenographic findings. The patient was 59 year-old male and admitted because of dyspnea-on-exertion for 30 years. Chest CT revealed right pleural mass abutting on the chest wall, measuring minus 80 hounsfield units. The mass was resected with calcified pleural plaque and confirmed to be lipomatosis with collagenous fibrosis arising from viserai pleura.

Pleural masses may be caused by various conditions, including benign and malignant neoplasms and non-neoplastic tumorlike conditions. Primary pleural neoplasms include solitary fibrous tumor, malignant mesothelioma, and primary pleural non-Hodgkin's lymphoma. Metastatic disease is the most common neoplasm of the pleura and may uncommonly occur in patients with hematologic malignancy, including lymphoma, leukemia, and multiple myeloma. Pleural effusion is usually associated with pleural malignancy. Rarely, pleural malignancy may arise from chronic empyema, and the most common cell type is non-Hodgkin's lymphoma (pyothorax-associated lymphoma). Non-neoplastic pleural masses may be observed in several benign conditions, including tuberculosis, pleural plaques caused by asbestos exposure, and pleural loose body. Herein, we present a review of benign and malignant pleural neoplasms and tumorlike conditions with illustrations of their computed tomographic images.

Primary malignant fibrous histocytoma(MFH) of pleura is very rare. Upon microscopic examination, the tumor was characterized by storiform pattern of growth and intense, diffuse immunostaining for $\alpha$ l-antichymotripsin. We report a case of primary malignant pleural fibers histiocytoma with extension to lung, which was managed by complete excision of pleural mass and lobectomy with thoracoplasty.

Pleural mesothelioma is usually divided into two forms of localized and diffuse type. Localized pleural fibrous mesothelioma is uncommon mesodermal neoplasm, which may occurs in both sexes and at the age of 50 years. This type of mesothelioma is usually asymptomatic and detected on routine chest X-ray and made fibrous tissue and shows of collagen fibers microscopically. Most localized fibrous mesothelioma arises from the visceral pleura and is well encapsulated and pedunculated mass. CT findings included well delineated, often lobulated, non-calcified soft tissue masses in close relation to a pleural space, associated pleural thickening, and absence of chest wall invasion and a peripheral or fissure location. Three cases of localized pleural fibrous mesothelioma diagnosed by resectional surgery were reported with the review of literature.

Subarachnoid-pleural fistula after routine thoracotomy is a rare complication but a very serious problem. Twenty one cases have been reported in the literature. We report a care of subarchnoid-pleural fistula that dveloped after the esecation of posterior mediastinal neurogenic tumor. The patient presented with large amount of clear pleural fluid with mild headache and dizziness. Surgical intervention following a trial of conservative therapy was undertaken because we strongly suspected subarachnoid-pleural fistula. A dural tear was found at the level of resected intercostal nerve root. The dura was closed by way of direct suture and fibrin glue. In this case, the recognition of subarachnoid-pleural fistula formation is difficult because the patient had not presented any neurologic deficit.

A 10-year-old castrated male Siba dog was presented for signs referable to pleural effusion associated with neoplasm of the thoracic cavity. The pleural effusion fluid consisted of blood and tumor cells by thoracocentesis. Histopathological examination of the sedimentary tumor cells revealed malignant mesothelioma. Intracavitary carboplatin was administered at 300 mg/$m^2$ every 5 weeks for 3 treatment and pleural effusion was disappeared after 3 treatments. The dog had recurrence of pleural effusion at 515 days but intracavitary carboplatin chemotherapy had no effect. It would be thought that the intracavitary carboplatin treatment was quite a useful method to control a canine malignant mesothelioma with minimal toxicity.

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.

Mediastinal teratoma is a tumor that thoracic surgeons made an operation much less commonly than other mediastinal masses and most of them are asymptomatic. But very rarely, this tumor invades the pleura and pericardium resulting in pleural effusion, pericardial effusion and cardiac tamponade in severe cases. The mechanism of invasion and perforation of the tumor is unknown and tumor-consisting tissue factor is suspected of a cause. In this case, we operated on a patient whose anterior mediastinal teratoma invaded and perforated pericardium and pleura resulting in pericardial effusion and pleural effusion. The patient was improved and discharged with no problem after resection of mass and involved pericardium.

Desmoid tumor (fibromatosis) is a histologically benign fibrous neoplasm showing locally infiltrating growth. This type of tumor commonly occurs in the abdomen, but intrathoracic desmoid tumor is uncommon. To date, 12 cases of intrathoracic desmoid tumor protruding into the pleural cavity, radiologically mimicking pleural masses, have been reported. Here, we report on a case of intrathoracic desmoid tumor protruding into the pleural cavity, and partially covered by parietal pleura. The main preoperative differential diagnoses included pleural solitary fibrous tumor, inflammatory pseudotumor or malignant mesothelioma. A near-total mass excision was performed. Pathologically, the tumor was composed of a paucicellular arrangement of spindle-shaped cells with fibromyxoid stroma. The resection margin was partially involved with spindle cells present. On histochemical staining, the spindle cells were strongly positive for vimentin and negative for CD34, consistent with a desmoid tumor. The patient was stable without further adjuvant treatment during 6-years of follow-up.

Pulmonary carcinoids are relatively rare tumors with low metastatic potential. Pleural carcinomatosis of a bronchial carcinoid has only been reported in 4 cases. Due to the rarity of this condition, there are no guidelines for its treatment or management. We report a case of atypical carcinoid with local recurrence and pleural metastases treated by video-assisted thoracoscopic surgery lobectomy and total pleurectomy with photodynamic therapy after non-radical wedge resection.
