A B S T R A C T Cytological criteria for the identification of glandular intraepithelial lesions (GIL) have not yet been fully described, especially for the precursors of adenocarcinoma in situ (AIS), thus these lesions may frequently remain unrecognized. As most patients diagnosed with AIS or mild to moderate GIL (grades I, II) are free from clinical symptoms, cytology has a very responsible role in the detection of these lesions. The aim of the study was to achieve the most appropriate cytologic diagnosis of intraepithelial lesions of endocervical columnar epithelium, analyzing the cytology findings in patients with histologically verified AIS and GIL (I, II). The value of cytology in the detection and differential diagnosis was assessed in 123 patients with definitive histologic diagnosis of glandular lesions (AIS, n=13; GIL I, n=11; and GIL II, n=7) epithelium (95.7%; vs. 74.2%). The accuracy of cytology was higher in pure (AIS, 61.5% and GIL I, II, 22.2%) than in mixed lesions (25.9% and 20.6%). Continuous improvement in cervical specimens and cytodiagnostic skills, better understanding of intraepithelial adenocarcinoma and precursors, and their inclusion in the classification of cytologic and histologic findings are expected to upgrade the detection of these lesions, and to reduce the invasive cervical adenocarcinoma morbidity and mortality.

The Pap test is designed as a screening test to detect primarily carcinoma of the cervix and its precursors, most often of squamous type. Rarely atypical or malignant cells found in cervical smear can be indication for the existence of an extrauterine disease. We present a case of a 26 year old woman with very small asymptomatic ovarian bilateral borderline tumors whose diagnosis was triggered by finding of atypical glandular cells with psammoma bodies on Pap smear. She had a history of abnormal Pap smears and was admitted to our Hospital for colposcopy. Pap smear was taken and reported as atypical glandular cells (AGC) with psammoma bodies. Colposcopically directed biopsy along with an endocervical curettage showed no abnormalities as well as transvaginal ultrasound examination. Three months later control Pap smear confirmed AGC with psammoma bodies (suggestive of endometrial or serous origin), ultrasound showed the presence of indistinctive, hyperechoic mass 2 cm in diameter in the left ovary along with slightly elevated CA-125 and diagnostic hysteroscopy and laparoscopy was performed. At laparascopy, both ovaries had surface cauliflower like papillary projections measuring up to 3 cm. A histological examination revealed bilateral serous borderline tumor.

This case presents Primary Squamous Cell Carcinoma of The Endometrium with cytological and immunocytological characteristics in specimens from endometrial aspirate, Pap smear and peritoneal washing. Initial TVUS and clinical examination showed no abnormalities, and the first curettage sample was interpreted as benign while the second was histopathologically inconclusive. The final histopathology diagnosis in the hysterectomy specimen confirmed the diagnosis of this rare tumour.
