The correct answer is B. Family history.
| The depigmented, irregular patches on the patient’s forearm are most consistent clinically with a diagnosis of vitiligo. Poor prognostic indicators that can suggest progression of vitiligo include family history, mucosal involvement, and koebnerization.
Younger age, recent onset, female sex, and unilateral involvement are not poor prognosticators of disease progression, and some of these may be protective from progression.
