Lichen Planopilaris As Part of Multiple Autoimmune Syndrome: A Case Report of New Association

Lichen planopilaris (LPP) is an uncommon inflammatory scalp condition. Its typical clinical presentation includes scaly, erythematous plaques resulting in irreversible alopecia. In this study, we report a female in her late 30s with hypothyroidism and Crohn's disease. She presented with gradual, localized hair loss that had been ongoing for the past four months. A thorough physical examination, and complemented by dermoscopic evaluation, confirmed the diagnosis of LPP. Individuals who have an autoimmune disease (AID) have a heightened propensity to develop additional AID. The coexistence of three or more AIDs falls under the definition of multiple autoimmune syndrome (MAS). This is the first case, to the best of our knowledge, of LPP being associated with MAS.

Concurrent autoimmune orofacial lesions: A rare occurrence!

Autoimmune disorders occur either as a solitary lesion or in pairs, but it is unusual to find two autoimmune disease lesions in the oral cavity in a single patient, who has been previously treated for psoriasis. We present the case of a 30-year-old male who presented with complaints of severe burning in the oral cavity. Examination revealed the presence of co-occurrence of vitiligo with oral lichen planus with a history of psoriasis and was managed conservatively with good response to treatment.
