Abstract

Wolffian tumors of the female adnexa are rare with only few cases reported. Their benign or malignant nature is not clearly defined in the literature and many of the malignant cases are probably misdiagnoses. The description of similar tumors harboring STK11 mutations has opened new pathways in understanding these tumors. In this review, we sought to present in detail the reported FATWO and STK11 adnexal tumors to understand their clinical and pathological features, and to discuss their differential diagnosis.

Keywords: FATWO; Mesonephric; Mesothelioma; Paratubal; STK11 adnexal tumor.
