AbstractThe normal physiological colour of plasma and urine ranges from yellow to straw-coloured. In this case report, we describe the occurrence of unusual, dark brown-coloured plasma and cola-coloured urine in a 42-year-man admitted to the Emergency Department. The patient presented with high-grade fever (102oF), chills, nausea, vomiting, dark stools, and dark urine for three days. The plasma was found to be dark brown in colour. He was diagnosed with Dengue hemorrhagic fever (DHF) and rhabdomyolysis (RM). He was closely monitored and treated successfully at our hospital. This case highlights the importance of plasma colour variations and also sheds light on a rare cause of dark brown-coloured plasma. Every case of brown colouration of the plasma must be promptly reported to the clinician and must also be mentioned in the patient report as this will help in timely diagnosis and favourable patient outcomes. Key Words: Blood plasma, Urine, Dengue fever, Rhabdomyolysis.
