A Lip Lump: An Unexpected Histological Diagnosis of a Lip Schwannoma.

Schwannomas are benign nerve sheath tumours arising from Schwann cells. They comprise 1% of all benign tumours. In the 2016 World Health Organisation Classification of Central Nervous System, they are classified as a tumour of the cranial and paraspinal nerves, Schwannoma 9560/0.

First report of squamous cell carcinoma arising within an intraoral radial forearm free flap.

Introduction: Oral epithelial dysplasia within free tissue reconstructions of the oral cavity has been reported. We report a case where squamous carcinoma arose within radial forearm skin transferred to the oral cavity 23 years previously. After a thorough literature search we believe this is the first report of such a phenomenon.

Small cell neuroendocrine tumour of the anterior tongue: A case report.

Introduction: Neuroendocrine carcinomas (NECs) are rare in the oral cavity. There is ambiguity regarding the classification of these tumours, but their aggressive nature is recognised throughout the literature. Merkel cell carcinoma (MCC) is rare and more frequent in skin, though it has also been described intra-orally.

Diagnostic biopsy of lymph nodes of the neck, axilla and groin: rhyme, reason or chance?

Introduction: Improving patient pathways of care is becoming increasingly important in the delivery of timely, appropriate surgical care. With this aim, we analysed the referral and management pathway of patients undergoing diagnostic superficial lymph node biopsy.

Patients And Methods: A retrospective review of case notes of patients undergoing diagnostic superficial lymph node biopsy over 3 years, 1998-2000 at the Bradford Hospitals NHS Trust.

Spontaneous cholesterol embolisation causing acute renal failure.

We present a case of true spontaneous cholesterol embolisation causing acute renal failure. There was no history of vascular procedural interventions or thrombolytic therapy prior to her presentation, but the patient did have a history of difficult hypercholesterolemia and atherosclerosis. This case highlights the importance of remembering cholesterol embolisation as a potential cause of acute renal failure despite no apparent precipitant, especially with the presence of unexplained eosinophilia.

Graves' disease and coexisting struma ovarii: struma expression of thyrotropin receptors and the presence of thyrotropin receptor stimulating antibodies.

Struma ovarii is a rare cause of hyperthyroidism and particularly rare in patients with coexisting Graves' disease. We describe a 28-year-old female who presented with symptoms and signs of hyperthyroidism (free thyroxine [FT(4)] 39 pmol/L, thyrotropin [TSH] < 0.05 mU/L) and associated ophthalmopathy, consistent with Graves' disease.
