An anterior neopharyngeal diverticulum is a recognized cause of dysphagia following laryngectomy. It is easily treated by endoscopic stapling.

The effect of a therapeutically administered high calorie diet in a severely malnourished patient is discussed in this case report. In patients with advanced head and neck cancer prolonged periods of malnutrition prior to admission are frequently encountered. This case report highlights the need to constantly monitor the electrolyte and vitamin levels during the early stages of instituting enteral or parenteral nutrition. By vigilant monitoring and a high index of suspicion re-feeding syndrome or severe hypophosphataemia and its associated complications can be avoided.

Images of fibrous dysplasia (FD) on computed tomography (CT) or magnetic resonance imaging (MRI) vary depending on the relative proportions of the fibrous and osseous components. Based on analysis of the literature, Camilleri suggested that structural changes revealed by conventional radiography may be indicative of the progression of FD. Here we describe the case of a boy who presented at 12 years of age with monostotic FD located in the right maxilla. The lesion first appeared as a lamellar, ‘onion peel’-like structure on CT; then over the course of the next five years, the structure became what has been termed an ‘egg-shell lesion’, before eventually assuming the form of a ‘ground-glass lesion’.

Vascular transformation of lymph node sinuses is an uncommon condition and only isolated cases have been reported. It is characterized by conversion of nodal sinuses into capillary-like channels, often accompanied by fibrosis. Venous or lymphatic obstruction is thought to be the underlying mechanism, and in most cases factors that may contribute to lymphovascular obstruction can be identified such as tumour in the vicinity, vascular thrombosis, heart failure, previous surgery or radiotherapy. Most cases involve abdominal lymph nodes, and head and neck involvement is rare. We present two cases of vascular transformation of lymph node sinuses presenting only as cervical lymphadenopathy, without an obvious cause of lymphovascular obstruction.

A case of malignant fibrous histiocytoma, which developed in the tongue of a 16-year-old girl is presented. Surgical excision with, or without, radical neck dissection is the treatment of choice of this type of lesion.
