Which primary bone cancer has the characteristic history of pain at night that is relieved by aspirin?

Osteoid osteoma is a benign primary bone tumor that has a characteristic history of pain at night that is relieved by aspirin.

The classic radiographic appearance of this lesion is a round or oval lucent lesion, which represents the nidus, typically measuring less than 1 cm and surrounded by a zone of bone sclerosis with cortical thickening. If larger than 1 cm, one should consider a Brodie abscess with osteomyelitis as an alternative diagnosis.
