An old destitute man, brought on a wheel chair, presented with multiple red itchy lesions all over the body for the past 3 months. On examination, multiple erythematous papules with and without excoriations were present all over the body, predominantly involving the trunk [Figure - 1]. Palms, soles and mucosae were spared. Dermoscopy of the cutaneous lesions revealed presence of a diffuse erythema with a central hemorrhagic punctum [Figure - 2]a. Ex-vivo dermoscopy of the wooden handle of the wheel chair revealed a number of bed bugs and their eggs hiding among the wooden crevices [Figure - 2]b and [Figure - 2]c.
