Extraskeletal chondromas are rare, benign cartilaginous neoplasms that are usually found in adults and often present as a slow growing solitary mass. We present a case of a 78-year-old male who initially presented with a painful hyperkeratotic lesion to the plantar aspect of his right foot resembling a porokeratosis. He noted increased pain when bearing weight. Initial radiographs revealed no osseous pathology, bone spurs or foreign bodies that correlated with the area of pain. Due to failed conservative treatment that consisted of regular debridement, surgical excision of the lesion was performed which revealed a large underlying hard nodule. The nodular mass was dissected from the underlying subcutaneous tissue and did not invade bone. The pathology report revealed chondrocytes within lacunae embedded in a matrix with surrounding perichondrium and had no malignant characteristics. The definitive diagnosis was chondroma. The post-operative period was uneventful and plantar pain was resolved almost immediately. Our patient, now, after a follow up of 1 year, is free of recurrence or pain.
