Figure 1: (a and b) Fine-needle aspiration cytology smears showing clusters and sheets of Hurthle cells in a background of numerous hemosiderin-laden macrophages (Giemsa, ×400). (c) On histopathologic examination, large areas of coagulative necrosis surrounded by a rim of viable tissue were noted (H and E, ×100). (d) Clusters of atypical follicular epithelial cells were present in the periphery (H and E, ×400). (e) Numerous hemosiderin-laden macrophages were seen (H and E, ×400).(f) Suspicious foci of capsular invasion by follicular epithelial cells were noted. Inset higher magnification of the same focus of suspicious capsular invasion (H and E, ×100)
