female adnexal tumour of probable Wolffian origin

A usually benign, unilateral and asymptomatic tumour of the broad ligament, fallopian tube, mesosalpinx, ovarian hilum, and ovaries of middle-aged (30–60) women, which has been variously regarded as a tumour arising in Wolffian remnants or representing extra-ovarian sex-cord stromal tumour.

Prognosis
FATWOs may rarely recur or metastasise.

Unlike endometrioid adenocarcinoma, FATWO is positive for inhibin and calretinin.
DISCUSSION: FATWO are rare neoplasms believed to originate from mesonephric (Wolffian) remnants because of its location in areas where these remnants are abundant, presence of a thick peritubular basal lamina and absence of cilia, secretary granules and glycogen.
CONCLUSION: Rarity and variable location of FATWO make the diagnosis difficult and in view of recurrence, long term follow up is necessary.
The pathology revealed a characteristic pattern for FATWO tumors, including solid neoplastic epithelial cells in "closely packed branching tubules," said Dr.
Steed and her associates revealed 72 reported FATWO cases, including 8 that recurred.
