Differential Diagnosis

  • Single most likely diagnosis
    • Diabetes Mellitus with neuropathy and skin manifestations: The patient's symptoms of painful neuropathy, erythematous macules and papules, and tinea versicolor-like lesions could be indicative of diabetes mellitus, especially considering the patient's age and ethnicity. Diabetes is a common condition that can cause neuropathy and skin changes.
  • Other Likely diagnoses
