A woman in her 40s presented to our clinic with itching over her lower back and buttocks for 2 days. Examination revealed multiple discrete 1 cm sized erythematous plaques over the lower back and buttocks, with one plaque over the lateral aspect of the right buttock showing a hyperpigmented spot simulating a crust [Figure 1]. Dermoscopy revealed a live 8-legged tick still attached firmly to the erythematous area [Figure 2]. Removal of the tick was done using radiofrequency device, taking care to completely separate the tick with its mouth part intact [Figure 3].
Dermoscopy of the isolated tick showed morphology consistent with Rhipicephalus sanguineus (commonly known as brown dog tick) which is known to be a vector for transmission of various Rickettsial diseases such as Indian tick typhus and ehrlichiosis. Entomodermoscopy serves as a precise diagnostic tool for tick infestations and helps in ensuring that the tick has been completely removed.
