TL;DR

A 44-year-old man with a long-standing tibial tuberous osteochondroma developed gouty stones, leading to painful symptoms and requiring surgical treatment.

Contribution

This case report highlights the rare combination of tibial tuberous osteochondroma with gouty stones.

Findings

Osteochondroma at the tibial tuberosity was confirmed via X-ray and surgical resection.

The patient's symptoms improved significantly after surgery.

Pathological analysis confirmed the presence of gouty stones in the osteochondroma.

Abstract

Osteochondroma (OC) mainly occurs in the metaphysis of long bones in children and adolescents, and it is extremely rare to occur in the tibial tuberosity and usually has no clinical symptoms. Here, we report a rare case of osteochondroma of the tibial tuberosity combined with gouty stones in a 44-year-old male patient who was found to have a mass on the left upper tibia for 20 years that had not been taken seriously or treated, and the patient was admitted to the hospital after the mass developed painful symptoms. In this case, X-ray examination clearly showed a lesion, which manifested as a limited bony protuberance with a wide base attached to the tibial tuberosity, and the imaging diagnosis was osteochondroma of the tibial tuberosity. The patient underwent surgical resection, and the pathologic results suggested that osteochondroma of the tibial tuberosity was combined with gouty stones. The patient’s symptoms improved significantly after the surgery, and no obvious discomfort or dysfunction has been found in the follow-up so far.
