Abstract:
We report here on a case of the giant and hyperkeratotic variant of porokeratosis. A 51-year-old man presented with a 30x20 cm sized extremely hyperkeratotic brownish verrucous plaque on his buttock. Histologic examination showed an increased number and size of the cornoid lamella, which displayed packed parakeratotic cells and the partial loss of the underlying granular layer. We diagnosed the patient with the giant and hyperkeratotic variant of porokeratosis on the basis of the clinical features and the characteristic histologic findings. Giant porokeratosis is a rare clinical condition among the several subtypes of porokeratosis, and the hyperkeratotic variant is an extremely rare clinical condition.
