We report a case of Kikuchi's disease presenting as cervical lymphadenopathy in an adolescent. The original histololgical diagnosis in this case was a metastatic neoplasm. We wish to highlight the importance of this rare condition because of its potential for mimicking malignancy.

A case is described in which recurrent laryngeal oedema was the presenting feature of thyroid lymphoma. Conventional isotope scanning was of no value in reaching the diagnosis.

The most common tracheal neoplasms are epidermoid carcinomas, papillomas and cylindromas. Kaposi's sarcoma, confined primarily to the trachea, is one of the rarest tumours. The clinical and histological picture of a case of Kaposi's sarcoma of the trachea in a young, pregnant woman, presenting with severe airway obstruction, is described here. The emergency tracheoscopy dislodged a mass from the trachea, which turned out to be a Kaposi's sarcoma on histology. Although Kaposi's sarcoma is one of the manifestations of AIDS, this patient had neither any underlying immunodeficiency nor any skin, visceral or lymphatic lesions.

The presentation, histology and management of a pseudosarcoma (or polypoid carcinoma) of the oesophagus are presented. Historical and modern theories of pathogenesis are discussed. Though rare, ENT surgeons should be aware of these tumours, as patients with such tumours present early and potentially have a much better prognosis than those with the more common oesophageal malignancies.

We described a 67-year-old man who had a right jugular foramen tumour expanding extracranially to the level of C2 cervical body. Paralysis of the glossopharyngeal, vagal, accessory, hypoglossal nerves and sensorineural hearing disturbance were found. The tumour originated from the accessory nerve and the histological examination revealed it was schwannoma. Accessory nerve as an origin of the jugular foramen neurinoma and its pre-operative neurological signs are reviewed.
