Subcarinal lymph node aspiration and cell block preparation. a) Haematoxylin/Eosin (H/E) stain in cell block of lymph node material contained numerous lymphoid aggregates (magnification x 40). b) in high power view (magnification x 400) the lymphoid cells were small in size with convoluted or “gyroid” nucleus and abundant clear cytoplasm. c,d) after conventional cytological preparation (Papanikolaou stain) the lymphoid cells were uniform with basophilic dark nucleus (magnification x 200, x 400).
