Morphologic features of endometriosis in various types of cytologic specimens.

Endometriosis is defined as the presence of endometrial tissue outside the uterine cavity. This study evaluates the cytomorphologic features of endometriosis in various cytologic specimen types [fine-needle aspiration (FNA), effusion cytology (EF), touch imprint (ToP), and cervical smear (PAP)], and assesses the key elements helpful in recognizing this lesion. A total of 18 cases (8 FNA, 4 EF, 5 ToP, and 1 PAP) of cytologically diagnosed and histologically/clinically confirmed endometriosis diagnosed between 1988 and 2006 comprises the material for this study.
