Penile dysmorphic disorder
Penile dysmorphic disorder, sometimes abbreviated as PDD, is a manifestation of body dysmorphic disorder where the main bodily area of fixation is the size, shape, or appearance of the penis. PDD on its own is not a recognized disorder, and there are no clinical standards to diagnose it in patients.
