Presentation of metastatic carcinoma as pedal stress fracture and ingrown toenail.

Metastatic lesions localized to the foot are rare. When present, such lesions are typically associated with a poor prognosis. A good history can help guide the clinician when formulating differential diagnoses for a questionable clinical presentation. We report the case of a patient presenting with findings indicative of a metatarsal stress fracture and an ingrown toenail, which eventually resulted in the diagnosis of metastatic disease from the lung. ACFAS Level of Clinical Evidence: 4.
