Aneurysmal bone cyst of the pubis: a case report.

An aneurysmal bone cyst is considered as a locally aggressive benign tumour. Intra-lesional extended curettage and bone-grafting is the mainstay of the treatment for aneurysmal bone cysts. Grafting is used usually in cases where the lesion compromises the mechanical strength of the bone. However, the massive size of the highly vascular tumour and the relative inaccessibility of its deeper extensions into the femoral vessels and the intra-abdominal structures, especially the urinary bladder, make it a relatively challenging case to perform excision and curettage.Presenting a case of a 15 years old male patient with the complaint of a right inguinal swelling since the past eight months. The swelling had started growing since the past two months and it was associated with pain. X-ray showed a lytic blowout legion of the entire right pubic ramus. An intra-lesional curettage was done. Complete tumour excision which was done by intra-lesional curettage and biopsy yielded satisfactory results with low complications and low recurrence of aneurysmal bone cyst of the superior ramus of the pubis.
