question 9 (mandatory) (10 points)
listen
the tumor of blood vessels of normal luminal size that is really a congenital malformation, and is seen most commonly in the skin and mucous membranes (sometimes referred to as a strawberry birthmark):
capillary hemangioma
cavernous hemangioma
hamartoma
kaposis sarcoma
hemangioendothelioma

Explanation:

• Capillary hemangioma: A benign vascular tumor. It is a congenital malformation. Commonly presents as a strawberry - like lesion (strawberry birthmark) on the skin and mucous membranes. Consists of closely packed capillaries.
• Cavernous hemangioma: Larger, dilated vascular spaces (caverns) rather than the fine capillary - like structure of a capillary hemangioma. Usually deeper in tissues and has a different gross and microscopic appearance.
• Hamartoma: A benign overgrowth of tissue native to the site. Not specifically a vascular tumor with the characteristics of a “strawberry birthmark”.
• Kaposi's sarcoma: A malignant tumor associated with human herpesvirus 8 (HHV - 8). Usually presents as purple - blue plaques or nodules, often in immunocompromised individuals (e.g., AIDS patients), and has a different pathogenesis and morphology.
• Hemangioendothelioma: A more aggressive vascular tumor (intermediate - grade malignancy in some cases). Does not match the description of a common, benign, “strawberry birthmark” - like lesion.

Answer:

Capillary hemangioma
