Nasal leeches and epistaxis: A case series.

Nasal hirudiniasis is uncommon in humans, where a leech invades through the nostrils, adhering to the nasal cavity mucosa. It is rare in urban areas, noted in endemic rural areas, but scarcely documented and, with urbanisation and ecological imbalance has become rarer still. It presents with recurrent epistaxis due to hirudin released by the leech while other symptoms are infinitesimal owing to an analgesic enzyme secreted. A thorough history-taking and examination is of utmost importance as respiratory complications may arise if the leech invades the airways. We present a case series of five patients, within a period of three years.
