Jena Had a Pimple That Left a Tiny Mark on Her

Jena had a pimple that left a tiny mark on her shoulder after it healed. She is now convinced that the mark is an enormous scar, and she is afraid to wear any garment that exposes her shoulder. She will not wear bathing suits, tank tops, or blouses that do not completely cover her shoulder. Her friends all tell her that the mark is barely visible, but she feels that it makes her entire upper body hideous to look at and she begs her parents for plastic surgery to correct it. Jena may be suffering from

A) body dysmorphic disorder.
B) orthorexia nervosa.
C) somatic symptom disorder.
D) conversion disorder.
