Psoriasis. Psoriasis is the prototype of psoriasiform epidermal hyperplasia. Microscopic examination of a lesion demonstrates that the rete ridges are uniformly elongated, as are the dermal papillae, giving an interlocking pattern of alternately reversed "clubs." The dermal papillae are edematous and reside beneath a thinned epidermis (suprapapillary thinning) with striking parakeratosis. The parakeratosis is the scale observed clinically.

Psoriasis. The clubbed papillae contain tortuous dilated venules. The prominent venules are part of the venulization of capillaries, which may be of histogenetic importance in psoriasis. The papilla to the right has one cross-section of its superficial capillary venule loop, which is normal. The papilla in the center shows numerous cross-sections of its venule, indicating striking tortuosity.

Psoriasis. Neutrophils migrate into the epidermis, emerging from the venulized capillaries at the tips of the dermal papillae. They migrate to the upper stratum spinosum and stratum corneum (arrows). In some forms of psoriasis, pustules are common clinical lesions.
