(A) Cytological features of a case of T‐cell lymphoma that was categorized as atypia of undetermined significance. The aspirate shows a mixed lymphoid pattern with small, intermediate‐sized, and large lymphocytes without distinct atypia (Papanicolaou stain, original magnification ×1000). (B) The histologic specimen shows a transition from an area of non‐neoplastic, small lymphocytes (lower right) to an area of atypical neoplastic lymphocytes (upper left; H&E stain, original magnification ×400).
