Abstract

Leeches are well known to migrate over the surface of the treated tissues. At times, they can be located in remote locations once they become engorged and detach. We report the first case of a leech tunneling through a dermal bite wound on a breast free flap.

Summary

First reported case of leech tunneling through a dermal bite wound on a free flap breast reconstruction. Highlights migration risk after engorgement and detachment.

Why This Matters for Hirudotherapy

This case report describes what the authors state is the first documented case of a medicinal leech tunneling through a dermal bite wound into a breast free flap reconstruction, noting that leeches are known to migrate over treated tissue surfaces and can detach in remote locations once engorged. The report is directly relevant to hirudotherapy practice as it highlights an unusual but potentially serious mechanical complication of leech application. The limitation is that this is a single case report with no comparative or incidence data, and the abstract provides minimal clinical detail about management or outcomes.
