A 52-year-old man presented with a periosteal chondroma in the base of the proximal phalanx of the right thumb. Magnetic resonance imaging (MRI) showed invasion of the bone marrow, which suggested malignancy. Although the clinical and MRI findings indicated a malignant tumour, the histopathological examination showed a benign periosteal chondroma.
We present a case of soft tissue chondroma arising from the soft tissues of the index finger of the right dominant hand. Although asymptomatic, the swelling gave rise to concern both for the patient and the hand surgeon. There was a relatively large osteoblastic lesion in relation to the volar aspect of the distal interphalangeal joint. The lesion was excised, the histological findings were those of a chondroma. The site, the radiological appearance and the lack of any connection of this tumor to the underlying joint, bone and tendon is extremely rare. Despite concerns of an aggressive neoplastic disease, the lesion was benign on histology and did not recur.
OBJECTIVE: We report a case of cricoid chondroma, underlining the difficulty in establishing a precise differential diagnosis between chondroma and low-grade chondrosarcoma of the larynx. MATERIAL AND METHODS: A 48-year-old woman developed inspiratory dyspnea. The final diagnosis was cricoid chondroma. We reviewed our case and data in the literature on these cartilaginous tumors. RESULTS: The patient was treated with conservative surgery. At 18 months follow-up, no recurrence has been detected. DISCUSSION: These tumors are rarely found in an ENT location and have similar histological features. According to many authors, the clinical course alone enables a distinction between chondroma and low-grade chondrosarcoma. Surgical treatment is indicated and provides good phonatory function in the vast majority of the cases.
