Coexistence of Hypothyroidism and Vitiligo Vulgaris: A Case Report

Vitiligo vulgaris is a chronic depigmenting disorder commonly linked to autoimmune diseases, particularly autoimmune thyroid conditions. We report a case of a 34-year-old female patient with well-controlled primary hypothyroidism for four years who, during a routine follow-up at the outpatient thyroid clinic in the nuclear medicine department of a tertiary care centre, noted the recent appearance of asymptomatic depigmented patches on her right forearm and left leg. Dermatological examination confirmed a diagnosis of vitiligo vulgaris. With no systemic symptoms and normal thyroid function, the coexistence suggests a shared autoimmune predisposition. This case highlights the importance of routine follow-up in identifying emerging autoimmune features and reinforces the value of a multidisciplinary approach in managing chronic autoimmune disorders.
