Background: Primary focal hyperhidrosis is a chronic, idiopathic, excessive sweating beyond the amount necessary for normal thermoregulation. It can affect one or more areas of the body, commonly the face, armpits, palms, or feet. This can cause great disruption in the quality of life of the patients and need to be treated properly. Various treatment options are available, including topical and systemic drugs, botulinum toxin type A injection, iontophoresis, microwave thermolysis, and surgery. Effective hyperhidrosis treatment varies among patients and may involve combination therapy. Case report: We report a case of primary palmar hyperhidrosis in a 33-year-old man. The patient had been using topical 15% aluminum chloride for 1 month without significant improvement. We administered intradermal botulinum toxin A injections, 100 IU for each palm, which led to marked improvements but still was not satisfying. Topical 10.8% aluminum chloride was given. Hyperhidrosis disease severity scale (HDSS) improved from 4 (severe) to 1 (mild). Discussion: Topical aluminum chloride is one of the first-line therapy for hyperhidrosis considering its safety, cost-effectiveness, and efficacy profile. Botulinum toxin A injection can be used in cases of severe hyperhidrosis or refractory to topical treatment. Nevertheless, not all patients respond to monotherapy approach, thus combination therapy can be recommended. Conclusion: In this case report, combination of intradermal botulinum toxin A injection and topical 10.8% aluminum chloride was found to be effective in controlling hyperhidrosis in a patient with partial response to monotherapy of either agent.
