Microcystic adnexal carcinoma (MAC) is known as an infiltrating but non-metastasizing tumour of the skin, that derives from sweat glands or follicular epithelium. We report on a rare case of MAC of the tongue. The patient had noticed the tumour for two years with slowly increasing dysphagia but no other symptoms of an oropharynx carcinoma. Histological and immunohistochemical analyses showed a similarity between the tumour derived from Ebner's glands of the tongue and MAC of the sweat glands.

A unique, previously undescribed case of iatrogenic perforation of a pharyngeal pouch which resulted in pharyngo-oesophageal fistulation is described. The correct management of such complications is discussed.

A patient complaining of pain and noise on turning her neck was diagnosed as having a large greater cornua of the hyoid bone. Excision of the greater cornua relieved the symptoms.

The ability of superglue preparations (cyanoacrylate) to bond instantly to skin as well as inanimate objects presents a special problem when instilled into the external ear canal. We present two cases of patients who had it successfully removed under the microscope with the help of acetone BP to debond it from the skin, without any damage to the meatus or the tympanic membrane. The third patient had the superglue removed without the help of acetone but sustained damage to the tympanic membrane. A literature review of similar cases is included.

We report the previously undocumented development of an orbital metastasis and skin metastases in a patient with polymorphous low grade adenocarcinoma (PLGA) 15 years after initial presentation. The clinical course, treatment and changing histological features are discussed.

Oncocytic metaplasia in laryngeal epithelium is uncommon. Oncocytes have been described in the lining of laryngeal cysts and such cysts have been reported in the literature under a variety of names. There is an ongoing debate about the exact nature of ‘oncocytic cysts’, which tend to be solitary. An unusual case of multiple oncocytic cysts of the larynx is described. The pathology and treament are discussed.
