Acquired progressive lymphangioma, also known as benign lymphangioendothelioma is a group of lymphangiomas that occur anywhere in young individuals, grow slowly, and present as bruise-like lesions or erythematous macules. [1]: 597 Acquired progressive lymphangioma may develop following radiation therapy, surgery, trauma, inflammation, and tick bites. The treatment of choice is complete surgical excision.
Acquired progressive lymphangioma appears as a slowly growing erythaematous to brownish, bruise-like, macule, plaque, or nodule typically located on the legs, head or neck. [2] The lesions are usually asymptomatic. [3]
Acquired progressive lymphangioma has been known to develop after radiation therapy, [4] surgery, [5] trauma, [6] femoral arteriography, [7] inflammation, [8] and tick bites. [9]
Because acquired progressive lymphangioma has been described following various traumas, it is thought to be a response to various inflammatory stimuli rather than a real neoplasm. [10]
Another possible pathogenic explanation is hormonal stimulation, as quickly growing lesions have been observed in numerous pubescent and prepubescent individuals. [11]
Finally, another idea proposed is that acquired progressive lymphangioma represents a complicated vascular hamartoma with three components: lymphatic vessels, blood vessels, and smooth muscle. [12]
Acquired progressive lymphangioma has thin-walled endothelial-lined gaps interspersed between collagen strands. [2] Endothelial cells show positive staining for lymphatic markers as podoplanin (D2-40), LYVE-1, and PROX-1. Additionally, the cells have variable levels of factor VIII, Ulex europaeus agglutinin I, CD31, and CD34. [10]
Acquired progressive lymphangioma is treated by complete surgical excision. [2]
