introduction: solitary fibrous tumours (sfts) of the nose and paranasal sinuses are extremely rare.these were originally described as neoplasms of the pleura originating from spindle cells. it is further sub-classified as a benign type of mesothelial tumour. its occurrence in many extra pleural sites have been reported earlier, mainly in the liver, parapharyngeal space, sublingual glands, tongu...

This study examined the mortality among shipbreaking workers from 1985 to 1997, after the shipbreaking industry was banned in 1985-1986. The study cohort consisted of men including 2,850 flame cutters, 871 lifters, 240 odd-jobbers and 225 other workers registered in 1985 at Kaohsiung Shipbreaking Workers Union. Mortality (n=336) data examined were obtained from the Vital Statistics Registry fro...

BACKGROUND Canine joint sarcomas, designated synovial sarcomas, are uncommon malignant mesenchymal neoplasms that occur in the large joints of the extremities of middle-aged, large-breed dogs. We report the diagnosis of an intrathoracic sarcoma with ultrastructural characteristics reminiscent of human synovial sarcoma in a dog. CASE PRESENTATION A 7-year-old female spayed Tibetan terrier cros...

Morphologically, mesotheliomas may be composed of epithelial and/or sarcomatous elements with various patterns, such as tubular, papillary, tubulopapillary, and diffuse epithelial or mixtures of these. Two cases are descirbed in which, in addition to typical mesothelioma, there was cartilage with foci of calcification and ossificated with the mesothelioma, which suggested that they formed an in...

Introduction. Primary splenic angiosarcoma is an extremely unusual neoplasm originating from sinusoidal vascular endothelium. Surgical extirpation is the mainstay of treatment of this highly malignant disease. Case Presentation. An 82-year-old woman was admitted with left pleural effusion and a palpable left upper quadrant abdominal mass, secondary to splenomegaly by two large splenic tumors. C...

Paraneoplastic limbic encephalitis (PLE) is a rare syndrome characterized by memory impairment, affective and behavioral disturbances and seizures. Among many different neoplasms known to cause PLE, small cell lung cancer (SCLC) is the most frequently reported. The pathogenesis is not fully understood but is believed to be autoimmune-related. We experienced a patient with typical clinical featu...

This retrospective study provides an overview on spontaneous diseases occurring in 38 captive wild felids submitted for necropsy by German zoological gardens between 2004 and 2013. Species included 18 tigers, 8 leopards, 7 lions, 3 cheetahs and 2 cougars with an age ranging from 0.5 to 22 years. Renal lesions, predominantly tubular alterations (intra-tubular concrements, tubular degeneration, n...

A previously healthy 50-year-old man was admitted with a repeated rapid heartbeat. Electrocardiograph on admission detected atrial fibrillation with an irregular ventricular rate of 170 beats/min for the first time. Transthoracic and transoesophageal echocardiography showed a 5×3.5 cm large sessile mass attached to the lateral wall of the left atrium (Fig. 1a) and a mild pericardial effusion. C...

Subsequently to the observation of a localized excess of mortality from malignant pleural neoplasms in the town of Biancavilla (Sicily), previously unknown amphibolic fibres with fluoro-edenitic composition were detected as naturally occurring soil contaminants. Less then two years after the initial report, ISS provided a set of public health recommendations that were complied by regional and l...

Malignant mesotheliomas are rather uncommon neoplasms associated primarily with asbestos exposure; however, they may also arise as second primary malignancies after radiation therapy, with a latency period of 15-25 years. Numerous studies have reported an association between pleural malignant mesothelioma and chest radiation performed for other malignancies; on the other hand, post-irradiation ...
