Myeloid Sarcoma That Infiltrated a Preexisting Sebaceous Lymphadenoma in the Parotid Gland: Diagnostic Challenges and Literature Review

Figure 5

(a) The sebaceous lymphadenoma in the parotid gland contained a biphasic tumor that consisted of epithelial and lymphoid components (×40). (b) Large neoplastic cells in the lymphoid-rich stroma were identified between the irregular epithelial nests (×400). (c) IHC staining for CK highlighted epithelial component (×400). (d) Scattered neoplastic cells between the epithelial nests were identified through the expression for myeloperoxidase (×400).
