For centuries, Hirudo medicinalis (medicinal leech) has been used as a remedy to treat many discomforts, such as muscle and joint pain. Nowadays, using leech in reconstructive surgery, microsurgery, wound and flap healing, venous insufficiency, varicosities and many other disorders has increased. In this study, we report a 45 year old female patient with six pruritic papules on her legs since10 months ago that appeared about 4 weeks after one session of leech application. Skin biopsy was performed on one of the papules, and in histopathology, superficial ulceration with a dense superficial and deep inflammatory infiltrate within the dermis composed of lymphocytes and eosinophils detected that considering history of leech application at this site, these constellation of data was compatible with the diagnosis of cutaneous lymphoid hyperplasia induced by leeches and the patient was cured by a topical steroid and cryotherapy.
