[Acrosyringial keratinocytes--no abnormal differentiation in psoriasis vulgaris].
Histochemical investigations were performed in normal and psoriatic epidermis to evaluate possible differences in the acrosyringial reactivity. Luminal (abundant in glycoconjugates, immunoreactive) and outer (almost nonreactive) epithelial cells could be distinguished. Psoriasis did not affect the staining pattern. The findings argue against a primary involvement of acrosyringial keratinocytes in the abnormal differentiation pathway of psoriatic epidermal cells. Moreover, they underline the relative independence of the acrosyringium from interfollicular epidermis.
