RESUMO
The confusing pathology of the proximal fifth metatarsal can make Iselin's disease difficult to distinguish from Jones', avulsion, or stress fractures, or os vesalianum. While lselin's disease appears to be rare due to the scarcity of cases in the medical literature, this may be due to misdiagnosis. The case report discusses the course of treatment for a young male with Iselin's disease that developed into a nonunion. The differentiating factors of the above-mentioned fractures are discussed.

An 87-year-old male presented with a painless, large mass on the dorsum of the left foot. He reported that the mass had first appeared 10 years ago and now had become so large that he could no longer tie his shoe. The mass originated from the proximal aspect of the second digit, encompassing the second web space and distal one third of the second and third metatarsals. Surgical excision of the mass was performed and pathologic diagnosis of the specimen confirmed a grade 1 chondrosarcoma. As expected with a lower grade chondrosarcoma, the patient did not have metastasis and fully recovered. While the occurrence of chondrosarcoma is not uncommon, it rarely affects the foot. This appears to be the third case of chondrosarcoma appearing in the proximal phalanx second digit of the foot.
