Peripartum pseudomalignant myositis ossificans of the finger

Idiopathic aggressive myositis ossificans of the hand infiltrating the flexor sheath/checkrein ligament, obliterating the common digital artery, and attenuating the digital nerve: A case report

“…We reviewed all previously reported cases of myositis ossificans of the hand and wrist since 1982 [ 2 , [4] , [5] , [6] , [7] , [8] , [9] , [10] , [11] , [12] , [13] , [14] , [15] , [16] , [17] ]. There was a total of 18 cases (including our case) and their data are summarized in Table 1 .…”

“…The majority of patients (n = 16) had tumors within the hand (fingers/web spaces/palm/thenar area) and only two cases had wrist lesions. Three lesions appeared during pregnancy [ 4 , 16 ]. None of the tumors invaded bone, although a periosteal reaction of the adjacent bone was seen in some cases [ 8 , 10 ].…”

“…Only two cases were successfully treated with conservative management [ 12 , 13 ]. Another three cases [ [4] , [5] , [6] ] were treated with ray amputation because of suspected sarcoma; and these cases included the case with extensor tendon infiltration [ 6 ]. The remaining cases (including ours) were treated with excision with no recurrence.…”

Myositis ossificans in the soft tissues of the hand

“…Nodular fasciitis is a condition sharing the clinical and histologic features of MO, except that the proliferating fibroblasts intermingle with a myxoid stroma and no definite bone formation is present [6,10].…”
