Gustatory otorrhoea: a rare case of congenital external ear salivary fistula.

OBJECTIVE: We present an extremely rare case of a 44-year-old woman with right gustatory otorrhoea and otalgia. CASE REPORT: The patient had been initially treated for otitis externa after Pseudomonas aeruginosa was grown from a microbiological swab. The otorrhoea fluid was collected and tested positive for amylase. Sialography and computed tomography imaging of the temporal bone confirmed a sialo-aural fistula from the right parotid gland to the bony external acoustic meatus. The defect was consistent with a patent foramen of Huschke. The fistula was identified surgically via a superficial parotidectomy approach, after contrast injection of Bonney's blue dye into the parotid duct, and then ligated and divided. The patient had immediate and sustained resolution of her otorrhoea. CONCLUSIONS: Sialo-aural fistulae are extremely rare, and usually arise as a complication of surgery or as an acquired disease process. To date, only four cases have been reported. This case demonstrates the use of sensitive investigation involving sialography and computed tomography, as well as successful surgical management, with complete resolution of symptoms.

Cross-sectional imaging of gastric neoplasia.

The detection of gastric neoplasia has traditionally been limited to barium examination and direct visualization at endoscopy. The rapid development of techniques such as multidetector computed tomography (MDCT) and endoscopic ultrasound (EUS) has resulted in more accurate diagnosis and staging of gastric neoplasia. In this review we describe the normal anatomy of the stomach with multi-modality illustrations and review the imaging manifestations of gastric neoplasia, including adenocarcinoma, lymphoma, neuroendocrine and gastro-intestinal stromal tumours. We also describe the optimal techniques for up-to-date and accurate gastric imaging, outlining the role of MDCT and EUS.

Schwannoma of tongue base treated with transoral carbon dioxide laser.

Schwannomas are benign slow growing solitary tumours of nerve sheath origin and can arise from any myelinated nerve. They have been reported to occur in most parts of the body with the highest incidence (25%) in the head and neck region, although tongue base lesions are rare. The tumour is resistant to radiotherapy, and therefore, the treatment of choice is surgery. We present a case of a tongue base schwannoma which was completely extirpated with a carbon dioxide laser via the transoral approach. The patient experienced virtually no morbidity from the use of the laser. Whilst tongue base schwannoma has been documented, we could not find an earlier report in the English literature describing our method of treatment. We conclude that transoral carbon dioxide laser can be added to the surgical armamentarium for the management of other similar cases in the future.

Life-threatening necrotizing fasciitis of the neck: an unusual consequence of a sore throat.

BACKGROUND: Necrotizing fasciitis is life-threatening bacterial infection which spreads with frightening speed along the fascial planes resulting in extensive tissue necrosis and often death. The infection is caused by either Group A streptococci or a combination of aerobic and anaerobic bacteria. Necrotizing fasciitis of the neck is rare and commonly has a dental origin. CASE REPORT: Here we present a unique case of the condition that was preceded by a sore throat in a young immunocompetent woman. We also describe, for the first time, a successful outcome involving primary skin closure and daily irrigation of the wound with hydrogen peroxide.
