🔬 Station 5 — Identification of Hemangioma
Rapid Revision • Morphological Recognition • Viva
🎯 Task
Examine the provided pathological specimen or image. Identify the lesion and describe the important morphological features that support your identification.
“`
Identification: This is a hemangioma, a benign vascular lesion composed of proliferating blood vessels.
Key morphology: The lesion is typically red to blue-red and vascular, with blood-filled spaces or channels.
Microscopy: It shows numerous vascular channels lined by bland flattened endothelial cells and containing red blood cells.
Pattern: Small capillary-sized channels suggest a capillary hemangioma, whereas large dilated blood-filled spaces suggest a cavernous hemangioma.
🔎 Stepwise Procedure / Approach
- Inspect the specimen or image systematically. Note whether the lesion appears vascular and red, blue-red or dark reddish.
- Assess its overall morphology. Look for a soft, spongy or blood-filled appearance where this can reasonably be appreciated.
- Look for vascular spaces. On a cut surface or microscopic image, identify multiple blood-containing channels or spaces.
- Assess vessel size. Decide whether the channels are predominantly small and capillary-sized or large and cavernous.
- Examine the endothelial lining. On microscopy, look for bland flattened endothelial cells without significant atypia.
- Confirm the vascular contents. Red blood cells should be visible within the vascular lumina.
- State the identification. Correlate the findings and identify the lesion as a hemangioma, mentioning the capillary or cavernous pattern when clearly demonstrated.
