Background:
Penile lymphangiomas are rare manifestations of lymphangiomas or lymphatic malformations which are more commonly found in the head or neck region of the body. Lymphangiomas are further categorized as lymphangioma circumscriptum, cavernous lymphangioma, cystic hygroma, or acquired lymphangiomas (also known as lymphangiectasia), based on their depth and etiology.
Results:
A literature review revealed only 30 cases of penile lymphangioma between 1947 and March 30, 2018. Several causes were attributed to the acquired penile lymphangiomas, including trauma, phimosis, and infection. While penile lymphangiomas can be initially mistaken for an infection, a thorough history and physical examination is sufficient to clinically diagnose a lymphangioma of the penis. Historically, surgical excision has been the gold standard of treatment for this condition. When asymptomatic, patients may opt for conservative management with avoidance of mechanical trauma alone. Other physicians have revealed novel treatment plans to rid patients of their penile lymphangioma such as a staged laser procedure.
Conclusion:
In this article, we elucidate the causes, symptoms, treatments, and outcomes associated with penile lymphangiomas found in the literature while also presenting the case of a 30-year-old African-American man diagnosed with acquired penile lymphangioma.
