Pleural-based giant solitary fibrous tumour with associated hypoglycaemia: unusual presentation with pulmonary hypertension in a patient with Doege-Potter syndrome.

Refractory hypoglycaemia in a patient with a solitary fibrous tumour (SFT) is very rare and was first reported in 1930 independently by Doege and Potter, leading to it being named 'Doege-Potter syndrome'. Here, we report the unusual case of a 77-year-old woman with a giant solitary fibrous pleural tumour who presented with complicating pulmonary hypertension and associated heart failure with hypoglycaemia, and subsequently underwent curative resection of the pleural mass with clinical improvement.

Lessons of the month: Co-infection with SARS-CoV-2 and influenza B virus in a patient with community-acquired pneumonia.

Why we only infrequently detect or report two or more respiratory viruses co-infecting an adult host is poorly understood. We report a rare case where influenza B and SARS-CoV-2 caused viral pneumonia in a 74-year-old man diagnosed during the UK winter epidemic/pandemic for these organisms and discuss concepts of co-infection.

DRESS syndrome: an important differential for eosinophilia with systemic organ dysfunction.

Drug rash occurring with eosinophilia and systemic symptoms syndrome is a potentially fatal adverse drug reaction that requires immediate action in order to minimise patient harm. Initially implicated with the use of anticonvulsants, it has also been shown to be caused by many other medications but less frequently with vancomycin. Patients typically present with fever, lymphadenopathy, eosinophilia and systemic organ dysfunction.

Lessons of the month 1: A case of rhombencephalitis as a rare complication of acute COVID-19 infection.

A 40-year-old man developed acute brainstem dysfunction 3 days after hospital admission with symptoms of the novel SARS-CoV-2 infection (COVID-19). Magnetic resonance imaging showed changes in keeping with inflammation of the brainstem and the upper cervical cord, leading to a diagnosis of rhombencephalitis. No other cause explained the patient's abnormal neurological findings.

Lumbo-sacral spine disease due to bovine tuberculosis in a patient with concurrent pulmonary disease.

Lumbo-sacral spinal disease due to bovine tuberculosis (TB) in a patient with concurrent pulmonary disease is rare. We report this unpredicted finding in an immunocompetent patient and discuss the natural history in an area of low prevalence.
