Background: Poland syndrome and Müllerian duct agenesis (Mayer-Rokitansky-Küster-Hauser(MRKH)-like syndrome) are two rare congenital anomalies with unclear etiology.
Case report: An 18-year-old female presented with hypoplasia of the left pectoralis muscles and subcutaneous tissue, hypoplasia of the left breast and nipple, and dextrocardia, typical in those with a severe form of Poland syndrome. She also showed aplasia of the vagina and uterus, bilateral ovarian agenesis, and hyperandrogenism, presenting as MRKH-like syndrome.
Conclusion: It is plausible to assume that these two congenital anomalies which arose from distant sites may be interrelated. More cases and further studies will certainly help delineate the pathogenesis of these syndromes.
