Atlas of Genetics and Cytogenetics in Oncology and Haematology (AGCOH) Adamantinoma of long bones is a low-grade, malignant biphasic tumor, characterized by a variety of morphological patterns, most commonly epithelial cells, surrounded by a relatively bland spindle-cell osteo-fibrous component.

Adamantinoma - 1o bone tumor with predilection for tibial diaphysis presenting during early adulthood Signs & Symptoms: - painful masses with variable symptom duration ranging from few months to few years Xrays: - well-circumscribed, eccentric, lytic lesions of tibial diaphysis - may be multicystic lesion with surrounding sclerosis - expansion of bone +/- intact cortex but no...

Radiographically, adamantinomas are sharply circumscribed lesions with lucent filling defects (central or eccentric in location). The tumors are separated from normal bone cortex by a sclerotic zone. Periosteal reaction is generally absent unless the lesion is accompanied by pathologic fracture. Gross pathology shows a well-demarcated lesion with peripheral lobulated contours....

Definition adamantinoma of long bones,a rare tumor of limb bones, usually the tibia, that microscopically resembles an ameloblastoma; the histogenesis is uncertain. Description of radiological appearance, Histology and treatment.

Adamantinoma is a rare tumor, and its origin remains controversial. Fischer first described the tumor in 1913, and since then, only approximately 200 cases have been reported. The tumor occurs almost exclusively in the long bones; tumors in the tibia account for more than 80% of cases. The diaphyseal region...

J Clin Pathol. 1982 July; 35(7): 780–786. Adamantinoma of long bones: clinical, pathological and ultrastructural features. A S Pieterse, P S Smith, and J McClure Abstract The clinical, pathological and ultrastructural features of two cases of tibial adamantinoma are described. Both lesions showed identical features with a mixed histological picture exhibiting baseloid, tubular...

Adamantinoma of the long bones is a rare, low-grade malignant neoplasm of unknown histogenesis, which affects mainly the tibia of young adults (Keeney et al., 1989). Sozzi et al. (1990) demonstrated a translocation t(7;13)(q32;q14) in a lung metastasis from an adamantinoma of the tibia in a boy who showed the...

Abstract Adamantinoma is a rare tumour of long bones whose pathogenesis is unknown. It occurs most commonly in the tibia. Although locally aggressive, recurrences are...

Adamantinoma is a primary low-grade, locally aggressive, malignant bone tumor of unknown histogenetic origin; however, current opinion suggests epithelial origin. Location is predominantly in the tibial diaphysis but can occur in the fibula and other long tubular bones. Very rare neoplasm: estimated 0.1-0.5% of all primary bone tumors....

Illustrated cases

Adamantinoma is a rare tumor that has a predilection for the tibia. This lesion occurs primarily in young people (age 15 to 35 years) and affects males and females almost equally. In the Mayo Clinic Series, the most common locations for adamantinoma were the tibia (about 80% to 85%) and...

Adamantinoma of Long Bone (extragnathic adamantinoma): Adamantinoma is a rare primary low-grade malignant tumor of bone that is locally aggressive. Adamantinoma of the long bone is not related to adamantinoma or ameloblastoma of the mandible and maxilla, which is derived from Rathke's pouch.

- rare tumor of unknown origin; - occurs primarily in young males between 10 - 30 years of age (most common after skeletal maturity); - pts present w/ firm, slowly enlarging mass that produces minimal disability; ...
