Figure 2: Haematoxylin and eosin staining of: (a) Normal skin section. Low power view of the cornifi ed layer (CL), epidermis (E) and dermis (D) (H&E, ×100). (b) Scabies mite infested skin biopsy showing: (a) epidermal tunnels (burrow) (b), mites inside the burrow (black arrows), denuded epidermis (d), and spongiosis (S) (H&E, ×100). (c) LP skin biopsy showing: hyperkeratosis (HK), irregular elongation of rete ridges (I), hypergranulosis (HG) and infl ammatory infi ltrate (IN F) at dermoepidermal junction (band-like infi ltrate) (H&E, ×200). (d) Psoriasis plaque biopsy in which all key features are present: hyperkeratosis with parakeratosis (Hy+P), regular elongation of reteridges(R) (saw-tooth appearance), neutrophil accumulation in stratum corneum (Munro microabscess) (M), diminished granul ar cell layer (DG) (H&E, ×200).
