Summary A strong correlation between capillary fenestrations and the demonstration of carbonic anhydrase (CA) has previously been shown. In the present histochemical study we sought to determine whether CA could serve as a marker for fenestrated capillaries in psoriasis. In normal human skin capillary staining for CA was found only in the fenestrated capillaries of the perifollicular and periglandular plexus. In psoriatic skin lesions, however, the intrapapillary capillaries also reacted for CA. From ultrastructural investigations it is known that these capillaries are fenestrated. Our findings have shown that there is a strong correlation between fenestrated and CA-positive capillaries in normal human skin as well as in the lesional skin of psoriatics. Therefore, the demonstration of CA activity may serve as a specific and sensitive marker for fenestrated capillaries in psoriasis using an uncomplicated method, which makes it possible to detect numerous fenestrated capillaries in a single histological section.
