Thymolipoma--a rare mediastinal tumour--report of two cases and review of literature.

Thymolipoma is a rare mediastinal tumour. We report two cases of thymolipoma. Our first case, a woman of 60 years, presented with an extremely rare association of myasthenia gravis with thymolipoma. Second case presented with dyspnoea productive cough in a male of 62 years. The relevant literature is briefly reviewed.

Malignant mesothelioma in the young (with prosthetic aortic valve an unusual association).

A case of malignant mesothelioma (MM) in a 15 year old boy is reported. He had a prosthetic aortic valve implanted in 1980 at our centre for rheumatic aortic regurgitation. Fever, weight loss and chest pain as initial symptoms suggested possibility of prosthetic valve endocarditis. Dysphagia as another initial symptom was interesting and caused further diagnostic dilemma. Role of Computerised Tomography (CT) scan in diagnosis of MM is highlighted.
