Where was the left vulvar mass located in the 51-year-old patient?

• A. Right labia minora mass
• B. Left labia majora mass at 5 o'clock position
• C. Left labia majora at 11 o'clock
• D. Right labia majora mass

Answer: (B)

In vulvar exams, location is often described with a clock-face system relative to the vaginal opening. The left labia majora at 5 o'clock means the mass sits on the left outer lip of the vulva, toward the lower/posterior portion. The labia majora are the larger outer folds, not the inner folds (labia minora), so specifying left labia majora distinguishes the tissue involved. The 5 o'clock position places the lesion in the lower-left region, not upper-left (11 o'clock) or on the right side, and not on the inner lips. Therefore, the left labia majora mass at 5 o'clock best matches the described location.
