Most tumors are associated with Peutz\u2014Jeghers syndrome and have a benign course and favorable prognosis; however, about 20% of sporadic sex cord tumors with annular tubules have a high risk of developing metastases. We present a case report about 18-year-old patient who presented with irregular menstruation and abdominal pain. Based on the histological features and immunohistochemical results, the diagnosis of a sex cord tumor with annular tubules was confirmed. The above-described ovarian tumor is rare in childhood and adolescence compared to the general population, which, combined with nonspecific clinical manifestations, can result certain diagnostic difficulties in this age group of patients.<\/jats:p>","DOI":"10.17116\/patol20258701148","type":"journal-article","created":{"date-parts":[[2025,2,12]],"date-time":"2025-02-12T15:57:17Z","timestamp":1739375837000},"page":"48","source":"Crossref","is-referenced-by-count":0,"title":["Sex cord tumor with annular tubules"],"prefix":"10.17116","volume":"87","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5223-9767","authenticated-orcid":false,"given":"A.S.","family":"Badlaeva","sequence":"first","affiliation":[{"name":"National Medical Research Center for Obstetrics, Gynecology and Perinatology named after Academician V.I.
