title: "Solid" variant of aneurysmal bone cyst.
abstract: A case of the so-called "solid" variant of aneurysmal bone cyst is reported. A 12-year-old girl with a few weeks' history of backache presented with a tender palpable mass located thoraco-spinal in the back at Th 3. Radiologically, the lesion was consistent with conventional aneurysmal bone cyst. Morphologically, it showed fibroblastic, fibrohistiocytic, fibromyxoid, osteoclastic and osteoblastic components as well as small aneurysmal sinusoids. Based on four other well documented cases, the clinico-pathological features and the differential diagnostical problems are discussed.
