bullous pemphigus is therefore not vulgar and doesn't pop = - Nikolsky sign. Hemidesmosomes are shot.
lets rule everything else out for completeness
Collagen type VII (i know wtf) = basement membrane btwn epidermis & dermis. NBME language synonyms = Basal Lamina, Reticular Lamina, Extracellular Matrix. Hemidesmosomes, which are made of integrin, fibronectin/laminin, bind to this collagen so it is close to correct but still wrong.
cytokeratin is that intracellular intermediate filament in epithelial cells used in stains to distinguish cancers.
Desmoplakin is apparently a part of desmosomes, which makes etymological sense. They are going for paraneoplastic pemphigus here. Sucks for them cuz we never learned that one haha. Gottem.
Aside here--FA 2020 just mentions desmosomes are made from desmoglein I and III. Antibodies against desmoglein I and III are seen in pemphigus vulgaris and against I is seen in scalded skin syndrome from Staph aureus via exfoliative toxin AKA exfolitoxin. That is why both diseases are + Nikolsky. Good old nikolsky
plakoglobin? nobody cares.
