This paper reports a case of ectopic decidual formation in the ovary (a so-called deciduoma) in a pregnant woman and discusses how intensive regressive changes in such lesions could lead to false diagnoses. The authors describe the lesion’s development in the context of the existing literature on ectopic decidua and related concepts. As a case report, the main limitation is that findings are based on a single example, making generalization difficult. Relevance to endometriosis: the paper’s background discussion includes prior work on the ectopic decidual reaction and its significance in endometriosis, though the paper’s main focus is ectopic decidual formation in the ovary.
