Abstract

Abstract: Aims: Haemophilic pseudotumor (HPT) is a rare but challenging complication of haemophilia. This study was intended to provide our experience about clinical characteristics and surgical treatment of HPT. Methods: Clinical medical records were retrieved from the Hemophilia Center, Nanfang Hospital, to identify the patients who had been surgically treated from 1 January 2006 to 31 December 2017 with a definite diagnosis of HPT. Their clinical features, surgical management, outcomes and complications after surgery were analysed. Results: We identified 34 patients with HPT who had surgical treatment over a 12‐year period and five of them had multiple HPTs. The incidence of HPT at this centre was 2.3% over the dozen years. A previous trauma leading to the development of HPT was reported in 18 cases (52.9%). The HPT affected only soft tissue in 7 patients, bone and soft tissue in 25 ones and joint in 2 ones. Preoperative infection and fistula formation happened in ten patients, two of whom were related to abdominal HPTs. Enterococcus faecalis was cultured in five cases with fistula formation. HPT associated with pathological fracture was observed in five cases, two of whom were treated by external fixation and 3 by HPT resection and metallic internal fixation. Amputation was performed for nine patients, 6 of whom had preoperative infection and fistula formation. Their follow‐up duration averaged 4.2 ± 2.9 years (range, from 1 to 13.5 years) after surgery. Of all our cases, three suffered from postoperative infection, five from recurrence of HPT and two with external fixation from fracture non‐union. Conclusions: HPT patients with preoperative infection had worse prognosis than those without. Surgical treatment plus intensive replacement therapy was effective for HPT but with a high rate of complications. HPT resection and metallic internal fixation rather than external fixation should be recommended for HPT patients with pathological fracture.
