Deep neck space abscesses are an uncommon but life-threatening emergency presentation to the ENT surgeon because of potential acute airway compromise.

This paper presents a novel case of a palatine tonsillar, low-flow, lymphovenous malformation pre-disposing to multifocal deep neck space collections and resultant acute airway compromise.

Only a few benign tumours of the middle ear have been reported to lead to the development of facial palsy. Here, we describe a patient with middle-ear cavernous lymphangioma and facial palsy.

Single case study.

A 61-year-old man presented with left-sided hearing impairment and incomplete left facial palsy. A tumour was confirmed to be occupying the epi- to mesotympanum and to be joined to the facial nerve. The tumour was removed along with facial nerve tissue, which was resected at its horizontal portion, and the remaining facial nerve was fixed by end-to-end anastomosis. Complete facial paralysis occurred after the operation, but the patient's House–Brackmann grade gradually improved to grade III. Post-operative histopathological examination revealed infiltration of the lymphangioma into the facial nerve tissue, together with mild neural atrophy of the facial nerve.

These findings suggested that tumour invasion was the cause of facial palsy in this patient.

We report a case of lymphangioma circumscriptum of the tongue, a very rare site of occurrence, which was successfully managed with intralesional bleomycin therapy.

We present a case report and review of available literature regarding lymphangioma circumscriptum of the tongue and the role of bleomycin therapy.

The patient was a 19-year-old man with a long-standing lesion involving the tongue, who presented with spontaneous, episodic bleeding over the previous few months. A diagnosis of lymphangioma circumscriptum was established on biopsy. Intralesional bleomycin injection resulted in successful resolution, and the patient remained asymptomatic over more than one year's follow up.

Lymphangioma circumscriptum is usually seen in the extremities and genitals. This case had a very rare site of occurrence, the tongue, and was successfully managed with conservative treatment, using intralesional bleomycin alone.

We report an adult case of cystic lymphangioma treated with OK-432 (Picibanil®).

A case report and review of the literature concerning the use of OK-432 to treat cystic lymphangioma is presented.

A 31-year-old woman developed a cystic lymphangioma four weeks post-partum. This was treated initially by aspiration, for diagnostic purposes. Investigation suggested that surgery would be challenging. A review of the literature demonstrated success with OK-432 in the treatment of this condition, although primarily in the paediatric population. This patient was successfully treated thus, and at the time of writing remained symptom free. A suggested management plan is outlined.

Treatment with OK-432 is useful in the management of cystic lymphangiomas in adults and should be considered as first line treatment.

We report a rare case of chronic facial pain following sclerotherapy for intraparotid haemolymphangioma, thereby highlighting an important clinical consideration when advising this treatment option as an alternative to surgery in the head and neck.

Case report, with a review of relevant literature.

Sclerotherapy of lymphangiomata is well reported in the literature. Unusually, our young patient with an intraparotid haemolymphangioma experienced severe, chronic pain following intralesional injection of sodium tetradecyl sulphate, which required management by a specialist pain service. We discuss the technique of sclerotherapy for such lesions, and also discuss the potential side effects of two agents commonly used in our centre: OK 432 and sodium tetradecyl sulphate.

Non-surgical treatments of lymphangiomata and venous vascular malformations are not without complication. Both patient and clinician should be aware of this, and of the other potential side effects of sclerotherapy, prior to its use in the head and neck.
