[Epithelioid hemangioma, a rare bone tumor]

Area of Science:

• Orthopedic Surgery
• Oncology
• Pathology

Background:

• Epithelioid hemangioma is a rare benign vascular tumor.
• Bone involvement by epithelioid hemangioma is uncommon, typically affecting long bones.
• Distinguishing epithelioid hemangioma from malignant vascular tumors via imaging is challenging.

Observation:

• A case of pathological hip fracture secondary to epithelioid hemangioma is presented.
• The tumor's location in the hip bone is unusual.
• Radiographic evaluation was insufficient for definitive diagnosis.

Findings:

• Epithelioid hemangioma can present as a pathological fracture in unusual skeletal locations.
• Surgical intervention is necessary for accurate diagnosis of bone epithelioid hemangioma.
• Histopathological examination confirms the diagnosis.

Implications:

• Highlights the importance of considering rare diagnoses in pathological fractures.
• Underscores the limitations of non-invasive imaging for certain bone tumors.
• Suggests curettage and filling as a potential treatment modality, pending further research.
