Great video! Just summarizing histologic signs: 1. acanthosis, in particular, rete will be elongated (test-tube or club-shaped +/- fusion of tips). 2. hypogranulosis 3. parakeratosis (related to hypogranulosis, both signs of high keratinocyte turnover) 4. munro microabscesses (neutrophils in stratum corneum) 5. tips of dermal pappilae can have prominent dilated capillaries guttate psoriasis: looks different clinically. acanthosis is more subtle. mounds of parakaratosis, with neutrophils.

Hey Doc, Ihave psosriasis on my face and neck. Do you think it is caused by a clogged lymphatic system? I don't really do any strenuous exercise, which I think drains the lymphatic system.
