Double osteoid-osteoma in adjacent carpal bones. A case report.

Osteoid Osteoma of the Trapezium: Case Report

“…In extremely rare cases, multiple distinct nidi may exist in the carpals. 5 Patients generally link symptoms to trauma, as in the present case. 10 Osteoid osteoma of the carpus may be misdiagnosed as carpal tunnel syndrome, de Quervain's tenosynovitis, reflex sympathetic dystrophy, arthritis, neuroma, aseptic necrosis, or infection.…”

“…9 The treatment of osteoid osteoma of the carpus is surgical removal of the nidus. [3][4][5][6] Recurrence is rare and is usually attributed to incomplete excision of nidus by curettage. In our opinion, trapeziectomy was not indicated for the treatment in this case, because the lesion did not extend to the trapeziometacarpal joint and the lesion was small.…”

Phalangeal osteoid osteoma

“…In addition, cancellous bone is more abundant and the cortices thinner compared with a typical tubular bone such as a femur (Williams & Warwick, 1980). This is the likely cause of a similar absence of periosteal new-bone formation in osteoid osteomas involving carpal bones (Rosenfeld et al, 1973;Herndon et al, 1974;Jensen, 1979;Alcalay et al, 1982).…”

Multifocal osteoid osteoma of tibia

“…Three cases were reported in the literature, one each in the humerus, proximal femur and fifth lumbar vertebra 2 11 12. Synchronous multicentric osteoid osteomas have been reported in three patients 5 13 14. In paediatric population, this lesion needs to be differentiated from Langerhans cell histiocytosis.…”
