A Case of Hailey-Hailey Disease Managed With Oral Magnesium Citrate and High-Dose Vitamin D3.
Hailey-Hailey disease, or benign familial pemphigus, is a rare blistering disease originally described in 1939. The disease is due to an autosomal dominant mutation in the ATP2C1 gene on chromosome 3, which encodes for an adenosine triphosphate-dependent calcium pump in the Golgi apparatus whose function is to maintain intercellular calcium homeostasis. Common treatments for Hailey-Hailey disease involve calcineurin inhibitors, topical corticosteroids, topical or systemic antibiotics, topical antifungals, ablative lasers, or botulin toxin. In this case report, we highlight a unique case of Hailey-Hailey disease that was resistant to many conventional therapies and ultimately managed with oral magnesium citrate and high-dose vitamin D3.
