Figure 2. (A) Tumor cells located within the encapsulated lymph node tissue. Some normal salivary gland tissue was found in the periphery area(H & E ×100). (B) The tumor cells showed small round blue tumor cells with a high nuclear-cytoplasmic ratio, round and oval nuclei, finely scattered chromatin (salt and pepper), obscured nucleoli and sparse cytoplasm (H & E ×400). (C) The tumor cells showed diffuse positivity for synaptophysin (IHC stains ×100). (D) The tumor cells were diffusely positive for CK20 and showed a classic dot-like paranuclear pattern (IHC stains ×400).
