Unusual osteochondroma of the foot and ankle.

Osteochondroma, also known as osteocartilaginous exostosis, is by far the most commonly occurring benign bone neoplasm. Its occurrence is the most frequent of all osseous tumors found in the foot. A basic review is discussed along with two case reports.

Sesamoid pain secondary to a plantar neuroma.

Two cases are presented in which the necessity of a plantar incision for removal of a fibular sesamoid led to the incidental finding of an undiagnosed plantar neuroma and bursal sac. The first case presented a hypertrophic fibular sesamoid fused to the plantar aspect of the first metatarsal head. The second case presented a dystrophic fibular sesamoid consistent with a healing fracture or avascular necrosis.
