Two cases are presented of bilateral traumatic inclusion cysts occurring on the dorsum of the first metatarsophalangeal joint. Both cases were women who wore high-heeled fashion shoes and the cysts occurred where the edge of the shoe impinged on a particularly prominent extensor hallucis longus tendon. Inclusion cysts have not previously been reported on the dorsum of the foot and their occurrence where impingement exists confirms a traumatic etiology. The importance of identifying the causative factor in such cases is emphasized.
