Aneurysmal bone cyst (ABC) is a rare benign lesion of bone. It most commonly involves meta-diaphysis of the long bones and posterior elements of the vertebrae. Solid variant of ABC (sABC) is extremely rare. It is benign but aggressive tumor thus requires early diagnosis and treatment. We report a case of sABC occurring in 20 yr male which involved proximal phalanx (pp) of the great toe. Magnetic Resonance Imaging (MRI) demonstrated an expansile osteolytic lesion with cortical thinning of medial aspect of base of pp and mild marrow edema of the great toe. Curretage was done and on histopathological examination (hpe) revealed large number of multinucleated osteoclast like giant cells with fibroblastic proliferation, areas of hemorrhage, hemosiderin-laden macrophages and woven bone along with few blood-filled cystic spaces and cartilaginous tissue. The diagnosis was established through a multimodal approach integrating radiological assessment and biopsy findings. Early intervention can lead to better prognosis.References
