[Hyperkeratosis punctata of the palmar creases].

The authors have collected 6 cases (one personal case and 5 cases from the literature) of hyperkeratosis punctata of the palmar creases, an affection which seems to be a new type of keratosis punctata. It is characterized by the development of small horny plugs in small cup-like depressions which are electively and exclusively found in the palmar flexion creases of the fingers. Histological examination shows a plug-like hyperkeratosis penetrating, more or less deeply, the depressed, funnel-like Malpighi's mucous layer which sometimes consists of one layer of cells.
