This paper highlights that morphological diagnostic limitations can lead to misinterpreting chocolate cysts as ovarian endometriosis, advocating for biochemical analysis of cyst fluid to differentiate between functional cysts and endometriosis.

This case report highlights the diagnostic challenges in distinguishing true ovarian endometriosis from hemorrhagic functional cysts, which are frequently misidentified as "chocolate cysts." The authors present a patient with a history of recurrent endometriosis to illustrate how atypical medical history and unexpected intraoperative findings can signal a benign functional origin rather than endometriotic disease. They suggest that biochemical analysis of the cyst fluid serves as a valuable tool for confirming the diagnosis when morphological assessment is inconclusive. This paper is centrally about endometriosis — specifically the differential diagnosis and potential misinterpretation of ovarian endometriotic lesions as functional cysts.

Abstract

Limitation of morphological diagnostic and possible misinterpretations are shown in a patient with anamnestic ovarian endometriosis. In cases of "chocolate cysts" it is necessary to differentiate between ovarian endometriosis and functional cysts. Hints for the existence of a functional cyst are an atypical past history or perioperative findings. Biochemical analysis of the cyst fluid may lead to a correct diagnosis.

Bei Vorliegen einer „Schokoladenzyste“ muß neben einer ovariellen Endometriose auch an die Möglichkeit einer eingebluteten Funktionellen Zyste gedacht werden. Hinweise finden sich dafür häufig in einer untypischen Anamnese oder durch untypische perioperative Befunde. Bei Verdacht auf eine funktionelle „Schokoladenzyste“ ist die biochemische Analyse des Zystensekretes hilfreich.
