Question 1: How would you best describe what you see in the pictures in appropriate morphological terms?
A. Left: Erythematous papules on labia majora. Right: White lacy striations (Wickham’s Striae) on the buccal mucosa with ill-defined borders
B. Left: Erythematous erosions of labia minora extending into vaginal introitus. Right: White lacy patches (Wickham’s Striae) on the buccal mucosa.
C. Left: Erythematous patch on labia majora. Right: Plaque of white lacy striations (Wickham’s Striae) on the buccal mucosa with well demarcated borders
D. Left: Erythematous plaque on labia majora, labia minora, and clitoris. Right: Patch of white lacy striations (Wickham’s Striae) on the buccal mucosa with well demarcated borders
Explanation:
When describing any rash, it is important to include important parameters, including location, number, demarcation, color, configuration, shape, distribution, primary lesion, and secondary lesion. In order to answer the question, it is necessary to learn the anatomy of female genitalia. Erosions are superficial open wounds with loss of epidermis or mucosa only. Papules are raised and palpable. Patches are flat, non-palpable with size > 1 cm diameter. Plaques are raised, palpable, solid with size > 1 cm diameter. Therefore, in the left picture, we have erythematous plaques with erosions and in the right picture, we have a patch of white lacy striations.
