Articular hemangiomata can be diagnosed prior to surgery in practically all cases, provided the correlation between the clinical picture and the pathological process is fully appreciated. These signs are significant: (1) the presence of a circumscribed mass, which is covered by normal skin and which increases in size when the extremity is in the dependent position; (2) the presence of blood after puncture of the mass; and (3) the disappearance of the contrast substance roentgenographically after injection into the vascular area. Surgical excision offers excellent end results.
