Osteoblastoma is a benign, aggressive and rare osteoblastic tumor. Its most common location is in later elements of the spine and sacrum. The cuboid presentation is exceptional.
A 50-year-old male who began her condition in 2005, with pain and increased volume in the dorsolateral region of the middle foot. X-rays show bone grafting and a cuboid lesion, radiotransparent, heterogeneous, multilobed, with irregular edges that exceeds the lateral cortical. Angiotomography was performed where hypervascularized injury was observed; bone scan showed uptake of technetium 99, and MRI reported an injury with post-surgical, cystic and multilobed changes. Trans surgical biopsy was taken, increased atypia-free cellularity and few multinucleated giant cells were reported and Enneking 2 qualified. Treatment was initiated with resection of the tumor, cryotherapy, and placement of tricortical graft in the bone defect. He exhibited good post-surgical evolution. At three years of the surgical procedure, he's without tumor and asymptomatic. Although osteoblastoma does not usually occur in cuboid, it should be taken into account as a differential diagnosis.
Bone tumors, despite having common locations, can occur in rare areas and therefore the complete radiographic and histopathological clinical study in each patient is critical.
