Palmoplantar keratoderma and pleomorphic adenoma of submandibular salivary gland: A rare association in a pediatric patient

Palmoplantar keratoderma (PPK) is a rare disorder in which dry, thick patches of skin develop on the soles of the hands and feet. Our patient, an 11-year-old boy was undergoing treatment for progressive PPK by a dermatologist since the age of 1 year. He presented to us with swelling in the left submandibular region. Incision biopsy was suggestive of pleomorphic adenoma (PA). Patient was managed with complete surgical excision of the left submandibular gland. The association of both the diffuse and punctate forms of PPK with internal neoplasia has been described by a number of reports. We report the occurrence of PA of the submandibular salivary gland in a case of diffuse PPK. To the best of our knowledge this association has never been described before.
