Vagabond's disease

Parasitic melanoderma (commonly known as Vagabond's disease, vagrant's disease and Greenhow's disease) is an exacerbation of body lice (scientifically referred to as Pediculosis).

Its clinical features include skin abrasion (excoriations) and abnormal skin discolouration (melanoderma) at the affected site.

It is caused by Phthirus pubis (crab louse) and characterized by subcutaneous hemmorrhages.
