What is the lymphatic counterpart of hemangiomas?

Explanation:
Lymphangiomas are the lymphatic counterpart of hemangiomas. Hemangiomas are proliferations of blood vessels, while lymphangiomas are malformations or proliferations of lymphatic vessels, typically dilated lymphatic channels lined by endothelial cells. They can resemble hemangiomas in presentation but are distinguished by their lymphatic nature (often expressing lymphatic markers like D2-40/podoplanin) and by their histology of dilated lymphatic spaces rather than blood-filled vessels. The other options are types of blood vessel lesions (capillary and cavernous hemangiomas) or a reactive vascular lesion (pyogenic granuloma), not lymphatic equivalents.
