Patient's question:
I am 39 years old and have recently discovered a 1.0 cm hard lump under the corona of the penis, inside the foreskin, which is painless and itchy.Doctor's answer:
Considering the possibility of penile sclerosing lymphangitis, penile sclerosing lymphangitis is characterized by subcutaneous cord-like masses on the penis, commonly occurring in areas such as the coronal sulcus and the back of the penis. It is often caused by local mild mechanical trauma, frequent or overly forceful masturbation, excessive sexual activity leading to local wear and tear, local trauma resulting in the obstruction of large lymphatic vessels within the subcutaneous tissue of the penis, and local infections of the penis.
