It highlights the diagnostic challenge of seronegative RPGN, in which MIDD should be included in the differential diagnosis. The case underscores the importance of integrated histopathology and hematologic genomics in identifying rare MGRS entities, recognizing that severe kidney injury may evolve rapidly despite appropriate management.

In DLBCL MYD88 L265P mutation is found in 32% of cases and it is significantly more prevalent in cases with the non-GCB phenotype (OR 5.78 p value = 2.07 × 10⁻⁵) and in DLBCL of extranodal locations (OR = 5.44 p value p < 0.001), including, not only immuneprivileged sites but also the skin, breast, upper respiratory tract, adrenal gland and bone and soft tissues. MYD88L265P mutation is highly specific of the non-GCB type DLBCL, likely reflecting MCD/C5 genetic features in a subset of non-GCB/ABC DLBCL.
