CLINICAL PRESENTATION:
A 68-year-old female patient with a history of endometrioid adenocarcinoma, who consulted for a right breast nodule detected during self-examination. On physical examination, nodules were palpated in both breasts. Ultrasound revealed a nodule in the right breast measuring 18x16mm and a nodule in the left breast measuring 10x9mm. Given the oncological history, a CT scan of the head and neck, chest, abdomen, and pelvis was performed, revealing a spiculated nodule measuring 21x17mm in the left apical lung lobe. Ultrasound-guided fine needle aspiration (FNA) was performed on both breast nodules. Six cytological smears were obtained from each site, fixed in 96° alcohol, and stained using the Papanicolaou technique. Slides were selected for automated immunocytochemical staining.
