REPORT OF A CASE
A 63-year-old man presented with a 6-week history of an asymptomatic "knotlike" lesion on his penis. The lesion was first noted about 4 weeks after his most recent sexual intercourse. The patient denied any history of venereal disease. The remainder of his medical history was insignificant.The physical examination showed an uncircumcised male with a 3.5×0.4-cm flesh-colored, arciform, cordlike lesion located on the right lateral aspect of the penis in the coronary sulcus (Fig 1). The overlying skin was freely movable and was not eroded, vesicular, or crusted. Several 1-cm, nontender, movable left inguinal lymph nodes were present. The remainder of the physical examination was normal. A 4-mm punch biopsy specimen taken from the penile lesion is shown below (Figs 2 and 3).What is your diagnosis?
Circular indurated lymphangitis of the penis (CILP) with concurrent syphilis.
