Summary
Glomangiomas are rare benign tumors. This case highlights an atypical knee glomangioma diagnosed using MRI and confirmed by histopathology, emphasizing the need for advanced imaging in unusual presentations.
Area of Science:
- Oncology
- Pathology
- Radiology
Background:
- Glomangiomas are rare, benign tumors originating from glomus bodies.
- Typically present with pain, tenderness, and cold hypersensitivity, often in extremities.
- Atypical presentations can occur in various locations.
Purpose of the Study:
- To report an unusual case of a large glomangioma on the knee.
- To illustrate the diagnostic process for atypical glomangiomas.
- To correlate imaging findings with histopathology.
Main Methods:
- Case report of a 49-year-old male with a large knee mass.
- Magnetic Resonance (MR) imaging for initial evaluation.
- Surgical excision followed by histopathological analysis.
Main Results:
- A large glomangioma (64mm×59mm×41mm) was found on the anteroinferior knee.
- MR imaging showed characteristic signal intensities and heterogeneous enhancement.
- Histopathology confirmed a benign glomangioma with specific immunohistochemical markers.
Conclusions:
- Atypical glomangiomas require advanced diagnostic methods beyond clinical presentation.
- MR imaging is valuable in diagnosing glomangiomas, especially in atypical locations.
- Histopathology remains the gold standard for definitive diagnosis of glomangiomas.
