Histologic examination revealed a compact column of parakeratosis resembling that of a cornoid lamella of porokeratotic conditions. Ultrastructurally in clinically affected skin, the stratum corneum contained numerous variable-sized pyknotic nuclei, and cells in the stratum granulosum contained fewer keratohyalin granules. The ultrastructural findings differed from those of porokeratosis of Mibelli and disseminated superficial actinic porokeratosis. The proper nosologic designation should be<i>punctate porokeratotic keratoderma</i>. (<i>Arch Dermatol</i>1988;124:1678-1682)Read More
