Hemophilic pseudotumor of the soft tissue of the hand: a case report.

A 25-year-old, right hand dominant man with a history of Hemophilia A, presented with an enlarging 2 x 3.5 cm mass on the dorsum of his dominant hand following minor trauma. Factor VIII activity level was 12 percent of normal. A diagnosis of hemophilic pseudotumor was made and the mass continued to enlarge despite medical management. Surgical intervention was carried out in order to prevent impending skin necrosis or rupture. The patient was treated by surgical excision of the lesion along with factor replacement therapy. The patient's symptoms resolved and he had no recurrence of the tumor.
