On gross examination, the specimen consisted of a well-circumscribed, solid-cystic whitish lesion. Histopathological findings on hematoxylin and eosin staining are shown in Figures 1 and 2. Immunohistochemical results are presented in Figure 3 (p40), Figure 4 (CD5), Figure 5 (c-KIT), and Figure 6 (TdT).
