Typical and special features of “LP type” DLBCL in composite lymphomas. a. Typical blast infiltrate with broad pale cytoplasm and lobulated LP cell-like nuclei (HE, 400×). b. Blast infiltrate strongly expressing EMA as observed in 73% of “LP type” DLBCL (EMA immunostaining, 200×). c. Expression of CD15 in the cytoplasm and Golgi field in 4 of 33 “LP type” DLBCL (CD15 immunostaining, 200×). d. Expression of CD10 in the cytoplasm and Golgi in 36% of “LP type” DLBCL (CD10 immunostaining, 400×). e. IgD expression in blasts observed in 4 of 33 “LP type” DLBCL (IgD immunostaining, 200×). f. JAK2 expression found in 43% of “LP type” DLBCL (JAK2 immunostaining, 100×).
