<unk> , also known as lymphangiosclerosis or sclerotic<unk> , is a skin condition characterized by a cordlike structure encircling the coronal sulcus of the penis, or running the length of the shaft, that has been attributed to trauma during vigorous sexual play. Nonvenereal<unk>  is a rare penile lesion consisting of a minimally tender, indurated cord involving the coronal sulcus and occasionally adjacent distal penile skin. The condition involves the hardening of a lymph vessel connected to a vein in the penis. It can look like a thick cord and can feel like a hardened, almost calcified or fibrous, vein, however it tends to not share the common blue tint with a vein. It can be felt as a hardened lump or "vein" even when the penis is flaccid, and is even more prominent during an erection. This disorder is fairly common and most often occurs after vigorous sexual activity and resolves spontaneously.
