A DLE plaque on the scalp is a chronic, scarring lesion with adherent scale and follicular plugging, not an acute, boggy, suppurative mass like a kerion.
This is a chronic, relapsing condition with multiple nodules and interconnecting sinus tracts, whereas a kerion is a single, acute inflammatory response to a fungus.
A psoriatic plaque on the scalp is characterized by thick, silvery scale, not the boggy, pustular, and tender inflammation of a kerion.
A gumma of tertiary syphilis can be a destructive scalp lesion, but it is a slow-growing granulomatous tumor, not an acute, boggy abscess.
This is self-induced hair loss from pulling, resulting in a patch of broken hairs of different lengths, not an inflammatory, suppurative mass.
