Recurrent Palmoplantar Hidradenitis with Exclusive Palmar Involvement and an Association with Trauma and Exposure to Aluminum Dust

  Recurrent palmoplantar hidradenitis is a benign, self‐limited inflammatory skin condition that has been reported to occur on the soles and palms of otherwise healthy children and young adults. Patients with the disease present with tender, erythematous and edematous plaques and nodules on the palmoplantar skin. We describe a child who had recurrent palmoplantar hidradenitis that occurred after trauma and exposure to aluminum dust and manifested as lesions localized to only the palmar surfaces. This case is presented to add exclusive palmar involvement to the diagnostic spectrum of recurrent palmoplantar hidradenitis and to review the proposed pathogenesis of the disease.
