Adipocyte Atrophy Mimicking Signet Ring Cell Carcinoma of the Gallbladder

Figure 1

(a, b) The subserosal tissue exhibits a prominent population of signet ring-like cells, associated with oedema and a delicate capillary network. (c) The signet ring-like cells show strong nuclear and cytoplasmic positivity for S100 protein. A small nerve (upper right) is also reactive for S100 staining.
