A Durlacher corn is a corn or heloma durum that occurs adjacent to proximal lateral aspect of nail of the little toe and can often be difficult to see clear distinction between the corn and nail. Durlacher’s corn is a hard corn within lateral nail sulcus of an axially rotated fifth, or occasionally fourth toe; cornified tissue may be difficult to distinguish from nail sulcus onychophosis. It is painful locally and will need to be expertly debrided by a podiatrist. This type of corn will return again unless what casues it is addressed.
The corn is named after the United Kingdom chiropodist, Lewis Durlacher (1792-1864) who first described it. In the USA, they call this a Lister’s corn.
