Acral microcystic lymphangioma: differential diagnosis in verrucous lesions of the extremities.

Lymphangiomas are a malformation caused by the abnormal migration of lymphatic tissue, leading to failures in the communication and drainage of the lymphatic system. They usually present as groups of translucent papules and vesicles in the skin or mucous membranes. Presentation as a verrucous plaque limited to a single toe is unusual and emphasizes the relevance of this case report.
