Flashcards in Pathology Terms Deck (10):
Increased thickness of the keratin layer
Persistence of nuclei in the keratin layer -> usually seen in psoriasis or pre-malignant conditions (epidermis is proliferating too quickly)
Increased thickness of epithelium
Irregular epithelial thickening
Intercellular oedema in the epidermis
Oedema between squames appears to increase prominence of intercellular prickles
If severe, vesicles filled by oedema fluid develop
Downward thickening of the epidermis between the dermal papillae
Lysis of intercellular adhesion sites
