Differential Diagnosis for Sweating on Palm and Foot and Itching

  • Single Most Likely Diagnosis
    • Hyperhidrosis: This condition is characterized by excessive sweating, which can occur on the palms and soles. Itching may accompany the sweating due to skin irritation or secondary infections.
  • Other Likely Diagnoses
    • Eczema (Atopic Dermatitis): This skin condition can cause itching and, in some cases, excessive sweating due to the body's response to inflammation.
    • Contact Dermatitis: An allergic reaction or irritation from substances coming into contact with the skin can cause itching and sweating.
    • Dyshidrotic Eczema: A type of eczema that specifically affects the hands and feet, causing small blisters, itching, and sometimes excessive sweating.
  • Do Not Miss Diagnoses
    • Thyroid Disorders: Both hyperthyroidism and hypothyroidism can cause changes in sweating patterns and skin sensations, including itching.
    • Diabetes: Uncontrolled diabetes can lead to peripheral neuropathy, which may cause itching sensations, and autonomic neuropathy, which can affect sweating.
    • Lymphoma: Certain types of lymphoma can cause itching (pruritus) without a rash, and while less common, could be associated with abnormal sweating patterns.
  • Rare Diagnoses
    • Pachyonychia Congenita: A rare genetic disorder that affects the skin and nails, potentially causing excessive sweating and itching.
    • Fabry Disease: A genetic disorder that can cause a range of symptoms, including itching, burning sensations, and possibly abnormal sweating due to autonomic dysfunction.
    • Complex Regional Pain Syndrome (CRPS): A condition characterized by intense burning or aching along with sweating and swelling in one of the arms, legs, hands, or feet after an injury or trauma, which might also include itching sensations.
