Oesophagitis dissecans superficialis is an extremely rare and benign condition where the mucosal epithelium of the oesophagus sloughs off along the whole length of the oesophagus and is expelled as an oesophageal cast. This condition has been reported in association with various aetiological factors. We report a case of an oesophageal cast in a patient who underwent repeated oesophagoscopy and dilatation for a postcricoid web. We discuss the possible relationship between trauma to the upper oesophagus and the development of oesophagitis dissecans superficialis.

Cysticercosis, caused by infestation with the pork tapeworm Taenia solium, is known to commonly involve the brain, muscles and subcutaneous tissue. Diagnosing cysticercosis can be difficult as its clinical presentation is usually non-specific. When involving subcutaneous tissue, it can present as firm, non-tender, solitary or multiple nodules. We report a case of subcutaneous cysticercosis at the nasion mimicking a nasal dermoid.

A case of pneumosinus dilatans of the frontal sinus is presented. The findings on serial skull X-rays, performed on three occasions over a 10-year period, seem to support a developmental aetiology for this rare condition.
