Removal of a Teratomatous "Twin".

The condition does not appear to be so generally well known as it ought to be. It has beenconfused with osteoma, syphilitic periostitis, and sarcoma, and mistaken diagnosis has had unfortunate sequelae. Thus Watson Jones (1940) cites a case in which a wife instituted divorce proceedings, as she was told the lesion was a syphilitic periostitis. Straus (1932) reports a case in which the entire second metatarsal was excised because of an erroneous diagnosis of sarcoma. Dodd (1933) reports the case of a woman who had a classical Lisfranc amputation of the right foot performed for a march fracture of the second metatarsal mistakenly diagnosed as a sarcoma.
