<prompt> Munros microabscesses are seen in:Stratum granulosumStratum corneumBasal layerPapillary tips  <response>: Ans. B. Stratum corneuma. In psoriasis the increased rate of proliferation to replace the damaged, exfoliated keratin is reflected in epidermal thickening acanthosis, down growth of elongated epidermal ridges, and increased mitotic activity.b. The stratum granulosum is thin or absent, and there is extensive overlying Parakeratotic scale. The dermal papillae are elongated and contain dilated capillaries; these extend close to the Parakeratotic scale due to thinning of the overlying epidermis.c. When the psoriatic scale is removed, this results in minute points of bleeding Auspitzs sign. Within the epidermis are focal areas of slight edema spongiosis; collections of neutrophils in the stratum corneum produce the characteristic Munros microabscesses.
