Definition
It is a condition characterized by focal replacement of the subcutaneous tissue of the penile shaft by a dense fibrous band connecting the tunica albuginea with the corpus cavernosum.
Clinical Features
Incidence
It occurs in less than 25 males per 100,000 subjects (Lindsay et al. 1991).
Age
The mean age of presentation shows a wide range, affecting men in the 3rd to 7th decade.
Sex
Male.
Site
The occurrence of a curvature in the erect penis, the curvature bending toward a fibrous plaque of variable size localized in the shaft is the typical occurrence. Painful, abnormal curvature of the penis or hard penile swelling is typical presentations.
Outcome
Malignant degeneration has not been reported.
Macroscopy
A palpable plaque on the penile shaft could be present as single or multiple nodules with partial calcifications.
