Intra-thoracic Tumour simulating Aneurism; with remarks on differential diagnosis

Pleural inflammatory myofibroblastoma: a locally aggressive intra-thoracic tumour

A 41-year old non-smoking woman presented with persistent pleural effusion. Pleural fluid was hemorrhagic and fluid cytology was negative for malignant cells. A working diagnosis of chronic haemothorax was made and standard right thoracotomy was performed to identify the source of bleeding. A 10 x 10 cms poorly circumscribed mass containing blood clots, altered blood, fibrous tissue, and gelati...

Intra-thoracic desmoid tumour in a patient with a previous aortocoronary bypass

BACKGROUND Intra-thoracic desmoid tumours with mediastinal invasion are very rare. Although rare they have to be taken into account in the differential diagnosis of a thoracic mass and therapeutic options have to be weighted since surgical treatment may require wide excision. CASE PRESENTATION A 48-year-old male diabetic, dyslipidaemic, former heavy smoker with psychiatric illness was operate...

Diagnosis and management of the intra-abdominal desmoid tumour

Desmoid tumours are a rare entity and are usually detected with a certain delay, as they initially often grow without causing any specific clinical symptoms. Although these tumours grow slowly and do not metastasise, their growth pattern remains aggressive and local tissue displacement or even destruction is common. Surgery remains the only potentially curative treatment option. Here we report ...

Two remarks on differential fields

We make two observations concerning differential fields. The first is a model-theoretic proof of the existence and uniqueness of a PicardVessiot extension for an iterative linear differential equation (in positive characteristic) answering a question of Hrushovski. The second observation is that definable sets of finite Morley rank in differentially closed fields of characteristic zero are (pos...
