Malignant granular cell tumour of the mediastinum.

This report describes a case of malignant granular cell tumour arising in the mediastinum, detailing the investigations undertaken to reach this rare diagnosis. A 63-year-old man was referred from the Pacific Islands for investigation of a 8cm mediastinal mass extending into the left pleura and associated with pleural nodules and pleural effusion. Needle aspiration via bronchoscopy yielded insufficient material for cytological interpretation and needle biopsy showed normal respiratory epithelium.

Lipedematous scalp in a child.

A nine year old Maori girl was noted to have a spongy consistency to her posterior scalp. The overlying skin appeared normal, as was hair growth in that area. The abnormal findings became more extensive over the subsequent year.
