A wedge biopsy of the contralateral ovary revealed endophytic superficial cell clusters with atypical features raising suspicion of malignancy. Detailed pathologic and clinical workup proved these foci as reactive ovarian surface epithelium contrary to various initial interpretations as metastatic, deciduoid, or histiocytic by expert pathologists.
