A 69-year-old man presented with cough, shortness of breath, and fatigue. He was initially treated for allergies and then for pulmonary embolism. Radiologically, a tumor mass was found to occlude the right pulmonary artery and involve the pulmonary trunk. A right pneumonectomy was performed. Histologically, a cellular malignant spindle and epithelioid tumor with areas of necrosis and brisk mitotic activity was seen. In some areas, the tumor appeared to form vascular channels. Focal osteosarcomatous differentiation was present. Immunohistochemical studies were performed including vimentin, smooth muscle actin, desmin, CD31, CD34, S100, and pan-cytokeratin. The tumor cells were positive for CD31 and vimentin and negative for pan-cytokeratin, CD34, and S100. Two months after surgery, the patient was alive and well.

A 9-year-old girl was admitted because of recurrent cough, dyspnea, and tachypnea for over 3 months, which had become worse for the preceding week. A chest X-ray revealed a mass in the lumen of the trachea. Fiberoptic bronchoscopy confirmed a polypoid mass in the upper trachea 3 cm under the vocal cords, with a 1.5-cm diameter that occluded approximately 70% of the lumen. Endoscopic excision of the neoplasm was performed with rigid bronchoscopy. Results of immunolabeling, which was positive for S-100 protein and vimentin, demonstrated a benign neurilemmoma. Clinical symptoms and signs improved after the tumor was removed. Intratracheal neurilemmoma is an extremely rare neoplasm, and only 34 cases were previously reported worldwide. The most common presentation is airway obstruction. Preoperative diagnosis is difficult, and radiographic techniques are helpful for diagnosis. Bronchoscopy is recommended for diagnosis, biopsy, and resection of the tumor. Long-term follow-up after simple enucleation is required.

A case of pleomorphic malignant fibrous histiocytoma of the right atrium and right ventricle is presented. Primary cardiac malignant fibrous histiocytoma (MFH) is extremely rare and its etiology and clinical course are not precisely known. We treated a 47-year-old female patient with persistent fever and cough, shortness of breath and anasarca. The patient died after eight months with symptoms of cardiac shock. Autopsy revealed a big soft yellow tumor in the right heart. Microscopically, atypical fibroblast-like cells, pleomorphic and multinucleated giant tumor cells with eosinophilic cytoplasm were observed within the myxoid and fibrous stroma. Immunohistochemically, tumor cells were positive for alfa-1-antitrypsin and partially positive for CD68 and vimentin. According to histopathologic and immunohistochemical features we diagnosed pleomorphic MFH.

Gastrointestinal stromal tumors GISTs are cellular spindle, or epithelioid tumors that occur in the stomach, intestine, and rarely in the esophagus. A 61-year-old man was complaining of resistant dry cough with dysphagia for one month duration. Upper gastrointestinal tract endoscopic examination showed a polypoid mass 30 cm from the incisors obstructing 50% of the lumen, where multiple biopsies were taken. Magnetic resonance imaging MRI showed a mass in the wall of the esophagus extending into the thoracic cavity. Histologically, the stained sections with the routine hematoxylin and eosin as well as the immunohistochemical stains for CD117, CD34, S100, vimentin, and smooth muscle actin confirmed the diagnosis of esophageal GIST. The patient was treated with imatinib, 400 mg/day. There was a dramatic reduction in the size of the tumor with successful improvement of his symptoms after 2 months of treatment, which was confirmed by repeated upper GIT endoscopy, and MRI.

Primary extrarenal rhabdoid tumors (RT) are now recognized as a specific entity in pediatric oncological pathology practice. We present an unusual case of a small cell myxoid variant of a thoracic RT in an infant and highlight the importance of recent molecular developments in the diagnosis of these tumors. An 8-month-old child presented with a short history of cough and shortness of breath. Imaging demonstrated a large mass occupying the majority of the thoracic cavity on the right side. A percutaneous needle biopsy of the mass showed fragments of tissue composed of malignant tumor with a predominant "small ovoid cell" phenotype and extensive myxoid change, with small nests and islands of tumor cells; occasional cells demonstrated open vesicular nuclei, prominent nucleoli, and eosinophilic cytoplasmic inclusions. Immunohistochemical staining revealed focal strong cytoplasmic positivity for cytokeratin, focal strong paranuclear cytoplasmic vimentin positivity, and INI1 staining showed normal nuclear positivity in control tissues but was negative in tumor cell nuclei. Electron microscopy demonstrated characteristic paranuclear whorls of intermediate filaments confirming the diagnosis of extrarenal malignant RT. The diagnosis of malignant rhabdoid tumor may be difficult, particularly in cases, such as the present, with a predominant small-cell myxoid phenotype. The characteristic expression patterns of cytokeratin and vimentin provide strong clues to the diagnosis, and the use of INI1 antibody now makes definitive diagnosis possible even on needle core biopsies.

A tracheobronchial neuroendocrine carcinoma in a 10-year-old cat with a history of coughing, dyspnoea and anorexia is described. Endoscopic examination revealed a yellowish mass protruding into the trachea and partly obstructing the right bronchial lumen. Histological examination of biopsy samples revealed a hypercellular tumour consisting of sheets or ribbons of small hyperchromatic cells, with oval to spindle-shaped nuclei and minimal cytoplasm; nucleoli and mitotic activity were absent. The findings were confirmed on post-mortem examination. The small neoplastic cells were immunolabelled to varying degrees by antibodies against neuron-specific enolase, S-100 protein, synaptophysin and vimentin. Ultrastructural studies revealed scattered neurosecretory granules and scanty cellular junctional complexes, including desmosomes and tonofilaments, in neoplastic cells.

An 8-year-old, male, mongrel dog developed severe cough and anorexia and died within 3 months. Autopsy revealed an invasive grayish-white mass in the right kidney and multiple nodules in the lungs, thoracic wall, and spleen. Histologically, the renal mass and the other nodules were mainly composed of papillotubular structures lined by oval-to-polygonal pleomorphic cells. The cells were reactive with DBA, PNA, and UEA-1 lectins and positive for vimentin but negative for CD10 and high molecular weight cytokeratin. Because of its histological, histochemical, and immunohistochemical similarities with human collecting duct carcinoma (CDC), a diagnosis of renal collecting duct carcinoma with pulmonary, thoracic, and splenic metastases was established. To our knowledge, this is the first case report of CDC in animals.

This report describes the clinical, histological and immunohistochemical features of two patients with primary pulmonary synovial sarcoma in the context of the literature. Chest pain, cough, haemoptysis and an enlarging pleural-based mass are the main clinical manifestations. Diagnosis depends on identifying epithelioid or spindle cells microscopically and on immunohistochemistry showing positivity for cytokeratin and vimentin and epithelial membrane antigen stains. Surgical excision is the main treatment approach.

A case of intraosseous schwannoma of rib is presented. A 22-year-old woman was admitted with paroxysmal thoracic pain, unproductive cough and a hard mass of the thorax. CT scan showed a unilocular osteolystic lesion in the rib. A needle biopsy was performed, and a diagnosis of intraosseous schwannoma was made. The patient underwent a partial excision of rib and the tumour was removed. Macroscopic examination revealed a 4 x 2 x 1.5 cm solid lesion with destruction of bone. Microscopically, the tumour showed typical features of schwannoma characterised by Antoni A and Antoni B tissues and Verocay bodies. Immunohistochemically, the tumour was positive for S-100 protein, vimentin, neuron specific enolase (NSE) and glial fibrillary acidic protein (GFAP). The patient is well without local recurrence or metastasis after a 1-year follow-up. This is believed to be the second case report of primary schwannoma of rib.

A 59-year-old woman was admitted to our hospital with a left lower lobe opacity and mediastinal shift on the chest X-ray. She had been complaining of intermittent nonproductive cough and exertional dyspnea. Chest computed tomography (CT) showed an endobronchial tumor of the left main to the lower bronchus, atelectasis of the left lower lobe, and mediastinal shift. Bronchoscopy revealed a polypoid tumor at the distal portion of the left main bronchus that occluded the bronchus. Biopsy specimens from the endobronchial tumor were shown to be serous papillary adenocarcinoma. Since the patient had been treated surgically for primary papillary serous carcinoma of the peritoneum (PSCP) 10 years earlier, immunohistochemical examinations were performed. The diagnosis of endobronchial metastasis of PSCP was confirmed by immunohistochemical staining with cancer antigen 125 (CA125), vimentin, and Wilms tumor-1 (WT-1). This is a rare case of endobronchial metastasis from PSCP.
