Description- SALL4 stands for Sal-like four could be a sensitive marker for endocrine seminoma/dysgerminoma, embryonal carcinomas, and food sac neoplasm in addition as their pathological process kind, together with those metastasizing to the system. An immunohistochemical panel, together with SALL4, OCT4, and CD30, helps solve this diagnostic issue. Germinoma are going to be positive for each SALL4 and OCT4 however negative for CD30, whereas carcinoma can show SALL4+/OCT4+/CD30+ profile, and food sac neoplasm can show SALL4+/OCT4/CD30 profile.
