Haemangiopericytoma refers to an uncommon vascular/perivascular neoplasm of which a minority of cases arise in the head and neck. It comprises a group of lesions with marked clinical and pathological heterogeneity and a lack of positive criteria by which to make a definitive diagnosis.

We describe an unusual case of such a tumour in the submental region, review its pathological features and discuss issues in management and prognosis.

Ecstasy is a class A controlled drug often consumed by the young population for recreational purposes. Documented complications of its use include hyperpyrexia, disseminated intravascular coagulation (DIC), renal failure and rhabdomyolysis. We report on two patients who developed pneumomediastinum after Ecstasy abuse. Both patients obtained and consumed the drug at the same establishment and presented to the same hospital within half an hour. The possible pathogenesis of this complication are discussed and the literature reviewed. Pneumomediastinum should be recognized as a possible complication of Ecstasy use. Conservative management is appropriate.

The existence of a combined benign schwannoma and lymphoma presenting as a nasal polyp has not been described in the English literature. We are reporting this rare combination in a 50-year-old male whose presenting symptoms were nasal obstruction, nasal deformity and headache. Examination of the left nasal cavity revealed a mass which was confined to the nose on computed tomography (CT) scan examination. Histopathology of the mass revealed a major component to be a benign schwannoma and a minor component a large B-cell lymphoma.
