Non-venereal sclerosing lymphangitis of the penis: A report of two cases
MetadataShow full item record
Non-venereal sclerosing lymphangitis (NVSL) is a rare disease that develops after vigorous sexual intercourse. The disease was first described in 1923 by Hoffman. The condition is observed usually in the second or third decade of life. NVSL is characterized by a rope-like hard swelling around the coronal sulcus of the penis. It is generally painless and benign and usually resolves spontaneously. Penile Mondor's disease (PMD) must be considered in differential diagnosis. The lesion is harder and adherent to the underlying skin in PMD. Patients often have pain. Venous Doppler ultrasound is normal in NVSL but increased echogenicity and incompressible veins are observed in PMD. Here, we report two cases of NVSL. Establishing the diagnosis and knowing the course of the disease by dermatologists and urologists is very important to avoid misdiagnosis, unnecessary laboratory examinations and treatment.
