Cutaneous Mucormycosis in a Young Immunocompetent Trauma Patient: A Case Report.

Introduction: Mucormycosis, a rare and life-threatening infection, is caused by microorganisms of the Mucorales order. It affects almost exclusively immunocompromised and diabetic patients, requiring extensive surgical debridement and prolonged antifungal therapy. Discussion/Results: We report the case of a 26-year-old immunocompetent woman, presenting with cutaneous mucormycosis after suffering blunt force trauma. This rare occurrence of mucormycosis in an immunocompetent patient reinforces the importance of elevated clinical suspicion and early initiation of adequate surgical and antifungal treatment. Conclusion: Mucormycosis is a challenging condition with potentially devastating consequences. Timely diagnosis and appropriate management are vital to mitigate the morbidity and mortality associated with this condition. LEARNING POINTS: Cutaneous mucormycosis is a rare life-threatening infection that affects mainly immunocompromised patients.Certain circumstances warrant a high index of clinical suspicion in immunocompetent patients, and indicate histopathological examination.Treatment involves a multidisciplinary approach with aggressive surgical debridement, antifungal therapy, and elimination of risk factors.

Acute flaccid paralysis due to multifactorial hyperkalaemia.

A male patient in his late 30s with a history of Lynch syndrome and colorectal cancer relapse, which recently started chemotherapy, was admitted to the emergency department with acute lower limb weakness that had progressed to all limbs and resulted in complete flaccid paresis with general areflexia. Blood tests showed severe hyperkalaemia, severe acute kidney injury and hyperuricaemia. Ultrasound showed bilateral hydronephrosis due to pelvic mass obstruction. Hyperkalaemia correction measurements were started as well as rasburicase with the assumption of tumour lysis syndrome and postrenal kidney injury. The patient showed a favourable clinical response with complete return of limb movement in the following hours and progressive recovery of renal function in the following days. This case highlights the need for prompt diagnosis and correction of severe hyperkalaemia, and its multiple possible causes, as it can lead to acute flaccid paralysis and a fatal outcome.
