Soft tissue chondroma case report and review of the literature

ABSTRACT

The present study presents a case report of extraskeletal chondroma or soft tissue chondroma, a rare and benign lesion, diagnosed by clinical findings, imaging studies and histopathological exam. The 24-year-old patient presented at the Orthopedics Section of Unimed Betim Hospital with a slow painless growth on the left thumb about 1 year ago. During the physical examination, a nodular lesion was noted; it had a hard consistency, was mobile and painless, and didn’t cause functional impairment for the finger. The patient was referred to the imaging unit of the hospital, where an X-ray was performed; later on, ultrasound and magnetic resonance imaging of the left thumb was done. After the imaging studies, the medical team chose excisional biopsy of the lesion. The histopathological examination confirmed the diagnosis of extra-skeletal chondroma or soft-tissue chondroma. Soft tissue chondroma is usually not considered for a soft-tissue tumor of the hand. Excision is easy and must be complete if recurrences are to be avoided. Histopathological evaluation is required for the final diagnosis.
