Coexistence of immunophenotypically normal and aberrant mast cells in patients with clonal mast cell diseases associates with more indolent subtypes and less severe disease characteristics.
Aberrant antigen expression on mast cells (MCs) is one of the most accurate diagnostic markers for clonal MC diseases (CMCD). Although the coexistence of normal and pathologic MCs is frequently seen, the disease characteristics associated with it have been minimally investigated. We aimed to gain further insight into t...
