The uncommon bronchiolitis obliterans organizing pneumonia can be idiopathic or caused by infection or medications. We report a 5 year old boy with pericardial sarcoma that was treated with chemotherapy (vincristine, doxorubicin, etoposide, cyclophosphamide) and radiotherapy. During the third cycle of chemotherapy, he developed progressive cough and dyspnea, needing oxygen therapy. Chest X-ray examination showed bilateral infiltrates. After discarding infectious etiologies, an open lung biopsy was performed, and the pathological examination showed a bronchiolitis obliterans organizing pneumonia. He was treated with prednisolone for 7 days, followed by prednisone for additional 45 days. He continued with fluticasone propionate as maintenance and remains in good condition with a chest X-ray showing mild interstitial images, after seven months of follow up.

The expressions of some growth factors have been immunohistochemically confirmed in several kinds of tumors, and in particular the expression of vascular endothelial growth factor (VEGF) has been reported to be closely related to tumor cell proliferation. We report herein a case of undifferentiated spindle-cell sarcoma arising in the chest wall with VEGF expression. A 67-year-old man, who presented with coughing, was found to have an abnormal shadow on his right chest wall. He was admitted to Chiba Rosai Hospital and preoperative diagnosis of the tumor was sarcoma. The tumor was thus resected along with the right chest wall and right lower lobe of the lung. Histopathologically, the tumor cells were spindle-shaped and showed severe atypism. The tumor cells were positive for vimentin and VEGF antibody with immunohistochemical staining, but they did not show differentiation to any special type of sarcoma. The tumor was diagnosed to be undifferentiated spindle-cell sarcoma. The microvessel density of the tumor was measured using CD34 and it was found to be higher than the average density of usual sarcomas. The prognosis of this case was poor. The patient died of tumor metastasis to the lung and bone 1 year later in spite of the fact that the tumor was resected.

A 68-year-old woman presented with a complaint of coughing and chestroentgenography and computed tomography revealed a very large, irregular mass in the left inferior lobe of the lung. The suspected preoperative diagnosis was sarcoma. Therefore, a complete resection of that mass was considered to be difficult. The patient received preoperative chemotherapy including cisplatin with vindesine as employed for non-small cell lung cancer. She demonstrated a clinical response after three cycles of the chemotherapy and underwent surgery successfully. A postoperative diagnosis of MFH was made based on the histology of the tumor, which was pleomorphic with a storiform pattern. The tumor cells showed positive immunostaining for alpha 1-antitrypsin and alpha 1-antichymotrypsin but were negative for SMA and S-100 protein. The patient underwent a further three cycles of postoperative chemotherapy and has remained disease-free for 12 months after tumor resection.

The Authors report a case of retroperitoneal sarcoma, in the histological subtype "liposarcoma", occasionally diagnosed in a 57 year old woman, who presented aspecific symptoms, characterized by dry cough, vomiting and chest pain. Chest TC showed a neoplasm of the retroperitoneum, close to liver, right colon, duodenum and right kidney. The arteriography of the right renal artery showed a neovascolarization inside the mass. A surgical resection was performed. The histological examination confirmed the diagnosis of liposarcoma. Liposarcomas account for 30% of the retroperitoneal soft tissue sarcomas; symptoms and diagnosis are late and the surgical resection of primary neoplasm, metastases and local recurrences representing the only therapeutic choice.

Primary pericardial sarcomas are extremely rare. The authors report a case of a 46-yr-old woman in whom a large mediastinal mass was discovered. The patient presented with cough, dyspnea, and orthopnea. Diagnostic investigations, such as echocardiography, computed tomography, and exploratory thoracotomy provided the evidence of a large mass in the mediastinum, attached by a broad base to the superior portion of the pericardium. A excisional biopsy was performed, and histologic examination of a biopsy specimen showed undifferentiated sarcoma. However, the complete removal of the mass was impossible due to adhesion to the adjacent great vessels. After the completion of the chemotherapy the patient was completely asymptomatic. However, follow-up transesophageal echocardiography showed a residual 3 x 4 cm-sized mass. The patient received the radiotherapy with a total dose of 55 Gy over 6 weeks. At present, there is no evidence of disease progression.

Choristoma in the larynx is rare and related to thyroid or glial tissue. The manifestation of salivary gland tissue in the larynx has not been reported to date. We present the case of an 80 year old male complaining of hoarseness and productive coughing. A left side tumourous swelling was seen in the larynx with intact vocal cord mobility. Using microlaryngoscopy the mass was resected without any intra- or postoperative problems. Histologically, a choristoma-heterotopic salivary gland tissue in the muscle and fat tissue--was found. The mucosa was intact and there were no signs of malignancy. Differential diagnosis of such masses in the larynx include benign lesions as well as specific infections, e.g. tuberculosis, sarcoidosis, amyloidosis and Wegener's granulomatosis. Especially in non-smokers, sarcoma, lymphoma and melanoma should be separated from the frequent squamous cell carcinoma of the laryngeal tissue. In rare cases, heterotopic tissue can mimic a tumourous mass. Intralaryngeal resection is the therapy of choice and should be recommended to the patient.

Granulocytic sarcoma is a soft tissue collection of leukemic cells. The authors describe a 4-year-old boy with M2 acute myelogenous leukemia (AML) who presented with fever, mild nonproductive cough, and hematemesis. Although he was initially diagnosed with nodular pneumonia, rapid resolution of a pulmonary infiltrate following induction chemotherapy was suggestive of a pulmonary granulocytic sarcoma. Interphase fluorescent in situ hybridization (FISH) of the lung biopsy specimen for the t(8;21)(q22;q22) translocation confirmed the retrospective diagnosis of a well-differentiated pulmonary granulocytic sarcoma. Pulmonary granulocytic sarcomas may be underrecognized in children with AML; this may delay anti-leukemic therapy and may lead to ineffective therapy if misdiagnosed as pneumonia.

Primary pulmonary artery sarcoma is an uncommon tumor. Mandelstamm in 1923 was the first to describe the disease in an autopsy. Since then, less than 200 cases were reported. The incidence is 0.001-0.03%, they are always highly malignant sarcoma, and women are involved twice as often as men. The presentation is often cough, dyspnea, and chest pain, and patients are usually diagnosed as suffering from pulmonary emboli, and primary tumor of the pulmonary artery is not usually considered in the differential diagnosis. The diagnosis of pulmonary artery sarcoma is made of the "clot" resected during pulmonary artery thrombendarterectomy. Our suggestion is that in patients with unilateral pulmonary artery occlusive disease, no evidence of positive hypercoagulability tests, and no history of thromboembolism, a high suspicion of pulmonary artery sarcoma should be kept in mind, and an angiographic-guided biopsy from the intra-arterial occlusive material should be considered. The treatment is surgery. The survival without operation is less than 2 months. Some patients were treated with adjuvant chemotherapy. We report on a woman with undifferentiated sarcoma of the pulmonary artery, mimicking chronic pulmonary artery emboli. This case illustrates the need to consider malignancy in the differential diagnosis of patients having pulmonary emboli.

Pleuropulmonary synovial sarcoma (PPSS) is increasingly recognized as a subtype of sarcoma because of the recent identification of a distinctive chromosomal translocation specific to synovial sarcoma. Soft-tissue synovial sarcoma is far more common than PPSS and typically develops in para-articular locations of the extremities; affects young and middle-aged adults, with no difference in distribution between the sexes; and has well-documented radiologic manifestations. PPSS may arise in the chest wall, heart, mediastinum, pleura, or lung, and it shares patient demographics and several imaging features with its soft-tissue counterpart. Patients present with a cough, chest pain, or dyspnea. On chest radiographs, PPSS typically appears as a sharply marginated mass with uniform opacity, based either in the pleura or in the lung, and often accompanied by an ipsilateral pleural effusion. Computed tomographic images show a well-circumscribed heterogeneously enhanced lesion without associated involvement of bone and without calcifications (except in the case of a chest wall primary tumor). Magnetic resonance imaging provides superior demonstration of nodular soft tissue and multilocular fluid-filled internal components of PPSS, in addition to peripheral rim enhancement after the intravenous administration of a gadolinium-based contrast material such as gadopentetate dimeglumine. Current treatment consists of surgical resection followed by chemotherapy, radiation therapy, or both.

Diffuse large B-cell lymphoma (DLBCL) with spindle cell components is extremely rare and often misdiagnosed as carcinoma or sarcoma. Here, we present a case of primary DLBCL with spindle cell components arising in the liver, for which a preoperative diagnosis by needle biopsies was unsuccessful. The patient was a 70-year-old man with a continuous cough. Thoracic computed tomography incidentally detected a mass of 5 cm in diameter in his liver. The initial and second needle biopsies from the liver mass were pathologically diagnosed as suspicious for sarcomatoid hepatocellular carcinoma. He underwent an extended left hepatectomy. Histological examination revealed a diffuse or epithelioid arrangement of round and polygonal cells, mixed with the fascicles of spindle-shaped cells. Immunohistochemically, all the morphological types of tumor cells showed positive reactions for a lymphocytic marker (CD45RB) and B-cell markers (CD20 and CD79a). Double-immunostaining revealed that the spindle-shaped tumor cells expressed CD20, but never expressed alpha-smooth muscle actin. Malignant lymphoma with a spindle cell morphology is quite uncommon, and this variant can be a diagnostic pitfall, especially in tiny biopsy specimens. We emphasize that pathologists should be reminded of lymphoma as a differential diagnosis of spindle cell tumors.
