[Rare location of an epidermoid cyst in the forefoot region with nerve compression syndrome. Contribution to the differential diagnosis of Morton's metatarsalgia (author's transl)].

The case of a rare location of an epiderman cyst in the forefoor region is reported. Very intense pain on pressure or tension in the plantar region of the second and third metatarsals suggested a metatarsalgia and the existing diffuse swelling a synovitis. Surgical revision revealed an epidermoid cyst the size of a hazelnut which pressed the N. digitalis plantaris communis against the head of the third metartarsal.
