Differential diagnosis of lesser metatarsalgia.

Pain in the lesser metatarsophalangeal area of the foot remains a diagnostic challenge. This pathology often is attributed to neuromas. These painful lesions, although predisposed to this area, are not nearly as common as they are thought to be. The "systems approach" to diagnosis can be extremely helpful in establishing an accurate cause and subsequent proper diagnosis of lesser metatarsophalangeal joint pain.
