Acquired lymphangioma of vulva secondary to radiotherapy to carcinoma of cervix; a case report and literature review

Acquired or secondary lymphangioma is a rare condition characterized by simple dilatation of surface lymphatic vessels, due to damage to the deep lymphatics by multitude of causes. Acquired lymphangioma has to be differentiated from lymphangioma circumscriptum (LC) which is a developmental defect of the deep dermal and subcutaneous lymphatics. Both conditions clinically and histologically resemble each other. However, the differentiation is possible on the basis of clinical history, because lymphangiomas are present at birth or early childhood, while acquired cutaneous lymphangiectasia develops later. Here we describe a case of acquired cutaneous lymphangioma of the vulva, secondary to radiotherapy to carcinoma of cervix.
