ASBESTOSIS AND PRIMARY INTRATHORACIC NEOPLASMS

Primary intrathoracic malignant mesenchymal tumours: computed tomography features of a rare group of chest neoplasms

OBJECTIVES To describe the computed tomography (CT) features in a case series of primary intrathoracic extracardiac malignant mesenchymal tumours (sarcomas). METHODS A 5-year retrospective research was conducted, and 18 patients were selected. CT exams were reviewed by two chest radiologists, blinded to tumour pathological type, origin and grade. Lesions were described in relation to location...

Primary intrathoracic neural tumours.

TERMINOLOGY Each axon cylinder is encased in a sheath of Schwann cells, and the tumour arising from this, the specific nerve sheath, is the Schwannoma or neurilemmoma. Groups of axon cylinders comprising a peripheral nerve are enmeshed in a non-specific sheath of fibrous tissue, and tumours arising from this non-specific nerve sheath are neurofibromata. In some nerve sheath tumours clear histol...

Abnormalities of the pulmonary artery resembling intrathoracic neoplasms.

Primary intrathoracic biphasic synovial sarcoma.

Synovial sarcomas are most frequently observed in the extremities. Although synovial sarcomas are the third most common histological type of soft-tissue sarcomas of the extremities, primary mediastinal synovial sarcoma is extremely rare. Monophasic synovial sarcoma is the most commonly observed subtype. whereas the biphasic subtype is less common. We present our case which was diagnosed as biph...

Primary intrapulmonary neurogenic sarcoma with hypertrophic pulmonary osteoarthropathy and asbestosis.

A case of primary intrapulmonary neurogenic sarcoma with hypertrophic pulmonary osteo-arthropathy and asbestosis is described. The essential histological features of this rare tumour are detailed, and the five authentic cases previously reported are reviewed. The pathogenesis of hyper-trophic pulmonary osteoarthropathy and its occurrence in this case are discussed. After surgical removal of the...
