Pemphigus vulgaris is a chronic autoimmune blistering disorder characterized by intraepidermal blister formation secondary to acantholysis, primarily affecting the skin and mucous membranes. Without adequate treatment, it follows a relapsing course with significant morbidity. We present the case of a 57-year-old male with a known history of pemphigus vulgaris who sought medical attention for a seven-month progressive blistering eruption with generalized distribution, associated with pruritus and refractory to outpatient corticosteroids and immunosuppressive agents. Upon admission, the patient was hemodynamically stable. Physical examination revealed flaccid blisters, erosions, and serohematic crusts involving the trunk, extremities, and scalp at varying stages of evolution. Laboratory findings showed leukocytosis with neutrophilia, relative lymphopenia, and elevated acute-phase reactants, with no evidence of renal dysfunction or coagulation abnormalities. During hospitalization, treatment included intravenous corticosteroids, azathioprine, antihistamines, and topical antibacterial therapy, resulting in a favorable clinical course with progressive resolution of active blisters into dry crusts and adequate wound healing. The patient was discharged on systemic corticosteroids, azathioprine, methotrexate, omeprazole, and prophylactic topical antibiotic therapy. This case underscores the critical role of inpatient management in recurrent and refractory pemphigus vulgaris. Optimization of immunosuppressive therapy, continuous monitoring, and prophylactic topical antibiotic therapy are essential to prevent complications and improve clinical outcomes.
