An unusual case of linear IgA disease affecting only the oral gingiva: a case report

BACKGROUND: We present a case report on desquamative gingivitis diagnosed as linear IgA disease (LAD), which is a rare autoimmune bullous disease exclusively affecting the oral gingiva. The oral mucosa can be impacted by various autoimmune bullous diseases, and our report focuses on this particular manifestation of LAD. CASE PRESENTATION: This patient presented with atypical symptoms, as frequent blister formation on the gingiva was the primary clinical manifestation. A combination of systemic and local treatment was administered to the patient. Following the treatment, there was a significant improvement observed in both the erythema and the bullous lesions on the gingiva. CONCLUSIONS: A more suitable local treatment strategy should be formulated for patients presenting with oral topical lesions, which clinicians can employ effectively.
