Cutaneous Pseudolymphoma As a Rare Adverse Effect of Medicinal Leech Therapy: A Case Report and Review of the Literature.Cureus. 2020 Apr 02; 12(4):e7517.C
Hirudotherapy (leech therapy) is one of the oldest practices in medical history, and nowadays it is used for several purposes in medicine. Salvage of flaps, wound healing, pain management, and treatment of varicose veins are among the common therapeutic applications of leeches. Complications associated with leech therapy include infections, bleeding, anemia, and allergic reaction. Cutaneous pseudolymphoma (benign proliferation of lymphoid cells in the skin) follows several underlying conditions. Although persistent arthropod bite reaction is one of the conditions associated with cutaneous pseudolymphoma, it has been rarely reported after medicinal leech therapy. Here we describe the case of a patient who presented with cutaneous pseudolymphoma after leech therapy as a rare cutaneous complication of hirudotherapy.
