Focal palmoplantar and gingival keratoderma is a very rare form of focal palmoplantar keratoderma characterized by painful circumscribed hyperkeratotic lesions on weight-bearing areas of soles, moderate focal hyperkeratosis of palmar pressure-related areas and an asymptomatic leukokeratosis confined to labial- and lingual- attached gingiva. Additional occasional features may include hyperhidrosis, follicular keratosis and extended oral mucosa involvement.
