| Summary: | Abstract Background Melkersson-Rosenthal syndrome (MRS), a rare granulomatous disorder, classically presents with recurrent facial palsy, orofacial edema, and fissured tongue. Associations with autoimmune diseases highlight its role as a potential marker of systemic immune dysregulation. Case presentation. A 21-year-old South Asian female presented with recurrent right facial palsy and fissured tongue. Serological testing revealed anti-SS-A (52 U/mL) and anti-RNP (> 240 U/mL) antibodies, leading to a diagnosis of oligosymptomatic MRS associated with anti-RNP-positive undifferentiated connective tissue disease (UCTD) with features suggestive of evolving mixed connective tissue disease (MCTD). Results Hydroxychloroquine therapy resulted in sustained remission at 6-month follow-up with normalization of inflammatory markers and significant reduction in anti-RNP titers. Conclusion This case underscores MRS as a potential early indicator of underlying autoimmune disorders including anti-RNP-positive UCTD that may evolve into MCTD. Comprehensive autoimmune evaluation and targeted immunosuppression are critical for favorable outcomes. |
