Gallbladder Ewing's sarcoma with liver metastasis: a rare case report

Ewing's sarcoma (SE) / primitive neuroectodermal tumor (PNET) occurs most often in soft tissues of the extremities and in the paravertebral areas. As far as we know, there are only two other reports in the gallbladder SE / PNET literature, however, this is the first metastatic case in a 58-year-old man. Microscopically, small round cell neoplasms showed intense positive immunoreactive activity for CD99, as well as for neuron-specific enoase and synaphysophine.

Cefepime-induced Cotard syndrome: a case report

Cotard syndrome features nihilistic delusions about one’s body or existence and is typically related to severe depression though is rarely associated with medical or neurological insults. The patient was a 62-year-old male with no past psychiatric history and a past medical history of congestive heart failure and consequent renal failure who presented for scheduled heart and kidney transplantation. He was started on routine post-transplant ganciclovir and steroids. Due to postoperative hypotension, empiric cefepime was initiated to cover for septic shock. One week postoperatively, the patient stated “I am dead.”

Extensive cervical necrotising fasciitis with mediastinitis in a COVID-19 positive patient: a case report

Necrotising fasciitis is a rapidly progressing soft tissue infection associated with significant morbidity and mortality. We present a case of cervical necrotising fasciitis with mediastinal extension in a diabetic young male who was COVID-19 positive. He presented with a five-day history of left-sided neck swelling which was fluctuant, red and painful. Subsequent debridement and management of the wound were complicated by the comorbid SARS-CoV2 infection due to potential need for proning. This case highlights the complex interplay between the management of two significant conditions; the surgical approach to necrotising fasciitis and the concern of deterioration due to COVID-19.

Fernando and Kelly report a paediatric case of a 6-year-old girl with neurofibromatosis type 1 (NF1) who presented with easy bruising and gum bleeding.
