| Wolff-Chaikoff block | Blocking of the organic binding of iodine and its incorporation into hormone caused by large doses of iodine; usually a transient effect, but in large doses in susceptible individuals it can be prolonged and cause iodine myxoedema. Synonym: Wolff-Chaikoff effect. (05 Mar 2000) |

| wolffian cyst | A cyst lying in the broad ligaments of the uterus and arising from any mesonephric structures. (05 Mar 2000) |
| wolffian duct | <radiology> MALE, vas deferens, vasa efferentia Female, Gartner duct cyst, hydatid cyst of Morgagni, epoophoron, paroophoron Cf: mullerian (para-mesonephric) duct (12 Dec 1998) |
| wolffian duct carcinoma | A rare tumour of the female genital tract, most often the ovary, formerly considered to be derived from mesonephric rests. Two varieties are recognised: (1) clear cell carcinoma, so called because of its histologic resemblance to renal cell carcinoma, and now considered to be of muellerian duct derivation and (2) an embryonal tumour (called also endodermal sinus tumour and yolk sac tumour), occurring chiefly in children. The latter variety may also arise in the testis. (12 Dec 1998) |
| wolffian rest | Remnants of the wolffian duct in the female genital tract that give rise to cysts; e.g., Gartner's cyst. Synonym: mesonephric rest. (05 Mar 2000) |
| wolffian ridge | One of the paired longitudinal ridge's developing in the dorsal body wall of the embryo on either side of the dorsal mesentery; the ridge is formed at first by the growing mesonephros and later by the mesonephros and the gonad. Synonym: genital fold, wolffian ridge. (05 Mar 2000) |
| wolffian tubules | Remnants of the mesonephric tubule's in the female, contained within the epoophoron. Synonym: wolffian tubules. (05 Mar 2000) |
