Dengue Fever Manifesting as Haemorrhagic Bullae: A Rare Presentation.

Dengue fever, a viral disease transmitted by Aedes mosquitoes, is a global health problem affecting millions of people each year. It is prevalent in tropical and subtropical areas, with epidemic potential due to climate change and increased travel. The disease commonly presents with cutaneous symptoms such as erythema, maculopapular rash and minor haemorrhagic lesions. This case is notable for the unusual presentation of haemorrhagic bullae, resembling drug eruption or autoimmune bullous disease. In the field of dermatology, tropical diseases like dengue have rarely been discussed. However, the recent increase in cases in Southeast Asia highlights the need for dermatologists to become familiar with dengue, as it often presents with diverse skin rashes. Herein, we report an unusual case of dengue fever presenting with haemorrhagic bullae.
