A 24-year-old male patient had road traffic accident dated January 2018, was taken to a nearby orthopedic surgeon, where he was diagnosed as having intra-articular distal radius fracture of the right side, and was operated 2 days after injury with anatomical distal radius locking plate. He was doing fine for 6 months after the index surgery; thereafter, he noticed a swelling in his lateral aspect of the right forearm for which he consulted his index surgeon, was advised course of oral antibiotics with regular follow-up. However, his swelling did not subside and was slowly increasing in size which made him to visit his index surgeon again where he was advised removal of implant. One month following removal of implant, he again noticed swelling now on his inner aspect of the right forearm which was also slowly increasing in size; he was advised ultrasonography and fine-needle aspiration cytology (FNAC). Sonographic findings were non-specific, but FNAC report suggested soft-tissue sarcoma and was finally referred to our tertiary care hospital for further management. Clinically, the patient was afebrile with no history of weight loss. Non-tender, ill-defined, and firm swelling was located on inner aspect of his right forearm; overlying skin was free with normal texture and normal temperature. Swelling was not fixed to underlying structure and regional lymph nodes were not enlarged. Routine laboratory and biochemical parameters were within normal rage except for mild raised erythrocyte sedimentation rate. Radiograph revealed malunited fracture of distal radius with evidence of screw holes of previous implant. Soft-tissue shadow was noticed adjacent to ulna with no evidence of bone erosion and/or periosteal reaction (). Here, the patient was advised contrast magnetic resonance imaging (MRI), which reported calcified soft-tissue mass measuring 8.3 cm × 1.6 cm × 10 cm situated in medial aspect of lower third ulna extending to ventral compartment of the right forearm, appearing isointense on T1WI and hyper- to hetero-intense on T2WI with intact overlying skin. The lesion showed peripheral rim enhancement on T1WI FS post-contrast image (). Ultrasound-guided core biopsy elicited dry tap possibly because of thick organized content. The patient was, therefore, planned for exploration and debridement. Curvilinear incision was given cantering over the swelling. Skin and subcutaneous tissue were excised along the marked incision. As the superficial fascia was cut and muscles were mobilized, a large gauze piece was found with surrounding granulation tissue and membrane. It was removed in toto and was sent for histopathological examination (). After debridement, wound was washed thoroughly with saline and closed in layers after careful inspection. Histopathological findings confirmed gauze piece with the presence of granulation tissues, focal necrosis, mononuclear cell infiltration, and giant cells. No evidence of tumor was documented. He was kept on intravenous first-generation cephalosporin for 5 days before hospital discharge. Recovery was uneventful; suture removal was done after 14 days. At the last follow-up, 10 months after operation, he is free of symptoms with no recurrence of swelling and resumed his normal activities.
