Keratotsis punctata of the palmar creases: report of two cases associated with ichthyosis vulgaris.
Two patients with keratosis punctata of the palmar creases are described. The association with ichthyosis vulgaris and other disorders of keratinization is discussed. In both cases, histopathology revealed a close relation between the keratotic plug and the sweat glands. The role of genetic factors and manual activity in the pathogenesis is discussed. Treatment with oral etretinate resulted in a good improvement in the first patient, but prolonged low-dose maintenance therapy was required to prevent recurrence.
