Which lesion presents as a cavernous hemangioma with large vascular spaces and tends not to regress?

• A. Capillary hemangioma
• B. Progenic Granuloma
• C. Lymphangioma
• D. Cavernous hemangioma

Answer: (D)

Cavernous hemangioma is defined by large, dilated blood-filled vascular spaces lined by endothelium. These big spaces give the lesion a cavernous appearance and tend to persist rather than regress, especially compared with capillary hemangiomas, which are made of many small capillary-sized vessels and often involute over time. Lymphangiomas involve lymphatic channels with lymph fluid rather than blood-filled spaces, so their histology is different. Pyogenic granuloma (lobular capillary hemangioma) is a rapidly growing capillary lesion that bleeds easily but does not feature those large cavernous spaces. So the description of large vascular spaces that tend not to regress points to cavernous hemangioma.
