A rare case of adenosquamous carcinoma of the hypophraynx is presented. The importance of primary surgical treatment is emphasised.

Many dental plates are made of materials that are radiolucent. If inhaled or swallowed they may be difficult to detect and where there is strong suspicion of inhalation, early bronchoscopy should be carried out even if plain X-rays show no abnormality. The details of three patients are reported.

The histopathological spectrum of neuroendocrine neoplasms of the larynx includes a subset that may be indistinguishable from a medullary carcinoma of the thyroid gland. For a patient who presents with a medullary carcinoma-like metastasis in a cervicallymph node and in whom there is no clinically demonstrable thyroid lesion, a laryngeal atypical carcinoid must be excluded. The literature's third example ofa primary medullary carcinoma-like atypical carcinoid of the larynx is presented.

Primary extramedullary piasmacytomas (PEMP) are uncommon plasma cell neoplasms that generally occur in the submucosal tissue of the upper airway. Salivary gland PEMP is an extremely rare condition. This report describes a unique case of PEMPin the parotid gland asociated with pulmonary amyloidosis. A review of all salivary gland PEMP's suggests that they behave similarly to PEMP's in other locations. The treatment of choice forlocalized disease is radiotherapy which should include regional lymphatics. Local controlcan be achieved in the majority of cases. The minority of patients develop systemic metastases and die from their disease. Chemotherapy can control disseminated disease and may induce remission.

Establishing a pre-operative diagnosis of lateral sinus thrombosis can be difficult, as the clinical features are non-specific and laboratory tests unhelpful. CT maydemonstrate abnormal high density of the lumen of the sinus, which does not enhance afterintravenous contrast medium. Enhancement of the dura surrounding the sinus may be prominent, causing the ‘empty triangle’ or ‘delta sign’ which may suggest the diagnosis. Magnetic resonance (MR) imaging may show both lack of flow and abnormal signal from the sinus, thus providing definitive evidence of thrombosis.

Verrucous carcinoma is a rare variant of squamous cell carcinoma which occurs most frequently in the oral cavity and larynx. In this article we describe a patient with verrucous carcinoma of the maxillary antrum. and present a review of the literature.
