disorder that primarily affects the lymph glands, c. 1400 (Lanfranc), scrophula, from Medieval Latin scrofulæ (plural) "swelling of the glands of the neck," literally "little pigs," from Latin scrofa "breeding sow" (see screw (n.)). The connection may be because the glands associated with the disease resemble the body of a sow or some part of it, or because pigs were thought to be prone to it. Compare Greek khoirades (plural) "scrofula," related to khoiros "young pig." Old English had the word as scrofell.

Perhaps via Gallo-Roman *scroba or West Germanic *scruva from Vulgar Latin scrobis "screw-head groove," in classical Latin "ditch, trench," also "vagina" (Diez, though OED finds this "phonologically impossible"). OED Seems to lean toward a group of apparently cognate Germanic words (Middle Low German, Middle Dutch schruve, Dutch schroef, German Schraube, Swedish skrufva "screw"), but these are said elsewhere to be French loan-words.
Kluge, Watkins and others trace it to Latin scrofa "breeding sow," perhaps on some fancied resemblance of the holes or furrows left by a rooting swine (compare Portuguese porca, Spanish perca "a female screw," from Latin porca "sow"). Latin scrofa in the "sow" sense is a specific Medieval Latin use; the word is literally "digger, rooter" (from PIE root *sker- (1) "to cut").
