Background: Chikungunya fever is caused by chikungunya virus which is transmitted by the bite of infected Aedes aegypti and A. albopictus mosquitoes. Aims: To study the various mucocutaneous manifestations in suspected cases of chikungunya fever. Materials and Methods: The patients who attended our outpatient department from July 2016 to October 2016 and fulfilled the criteria for “suspect cases” of chikungunya infection stipulated by the National Institute of Communicable Diseases, Directorate General of Health Services, Government of India, were included in the study prospectively. A total of 112 patients (62 males and 50 females) with mucocutaneous manifestations of chikungunya fever were enrolled in the study. Results: Mucocutaneous manifestations were found more in males than females. Serological immunoglobulin M enzyme-linked immunosorbent assay (IgM ELISA) test for chikungunya virus was positive in 62 (55.3%) patients. Generalized erythematous maculopapular rash (53.5%) was the most common finding. Genital pustular rash with aphthae (4.4%), oral and intertriginous aphthae, red lunula, subungual hemorrhage, localized erythema of the ear pinnae, erythema, swelling, and eczematous changes over the preexisting scars and striae (scar phenomenon) were the other interesting findings. Various pattern of pigmentation (37.5%) were observed including striking nose pigmentation in a large number of patients, by looking at which even a retrospective diagnosis of chikungunya fever could be made. There was flare-up of existing dermatoses like psoriasis and dermatophytic infection. Conclusions: Wide varieties of the mucocutaneous manifestations were observed in our study, but the striking nose pigmentation was present irrespective of age and this peculiar pigmentation may be considered as a specific clinical marker of chikungunya fever. Chikungunya fever must be suspected in any patient with painful oro-genital and intertriginous aphthous-like lesions associated with febrile polyarthralgia with rash.
