Histopathology showed an undifferentiated carcinoma
probably of thymic origin (optical microscopy showed poorly differentiated carcinoma cells with frequent atypical mitosis in the thymic mass which was covered by a hyaline capsule; the immunohistochemistry showed a CD5 positivity along with negative TTF1, negative PSA, negative Ck7, negative CROMO, negative SYNAPTO, and positive CK34BetaE12, P63, and PSMA).
