  • Refined diagnostic criteria and classification of mast cell leukemia (MCL) and myelomastocytic leukemia (MML) : a consensus proposal

    • Mast cell leukemia (MCL), the leukemic manifestation of systemic mastocytosis (SM), is characterized by leukemic expansion of immature mast cells (MCs) in the bone marrow (BM) and other internal organs; and a poor prognosis. In a subset of patients, circulating MCs are detectable. A major differential diagnosis to MCL is myelomastocytic leukemia (MML). Although criteria for both MCL and MML have been published, several questions remain concerning terminologies and subvariants. To discuss open issues, the EU/US-consensus group and the European Competence Network on Mastocytosis (ECNM) launched a series of meetings and workshops in 2011-2013. Resulting discussions and outcomes are provided in this article. The group recommends that MML be recognized as a distinct condition defined by mastocytic differentiation in advanced myeloid neoplasms without evidence of SM. The group also proposes that MCL be divided into acute MCL and chronic MCL, based on the presence or absence of C-Findings. In addition, a primary (de novo) form of MCL should be separated from secondary MCL that typically develops in the presence of a known antecedent MC neoplasm, usually aggressive SM (ASM) or MC sarcoma. For MCL, an imminent prephase is also proposed. This prephase represents ASM with rapid progression and 5%-19% MCs in BM smears, which is generally accepted to be of prognostic significance. We recommend that this condition be termed ASM in transformation to MCL (ASM-t). The refined classification of MCL fits within and extends the current WHO classification; and should improve prognostication and patient selection in practice as well as in clinical trials.

  • Genetic data reveal that water frogs of Cyprus (genus Pelophylax) are an endemic species of Messinian origin
  • 2012
  • Ingår i: ZOOSYSTEMATICS AND EVOLUTION. - 1860-0743. ; 88:2, s. 261-283
  • Tidskriftsartikel (refereegranskat)abstract
    • Water frogs inhabiting Cyprus represent a distinct evolutionary species of Messinian origin that is formally described in this paper. The systematic status of Cypriot frogs is evidenced by specific characters in their mitochondrial (mt) and nuclear (nu) DNA sequences, and the fact that they form a well supported monophyletic clade in both mtDNA and nuDNA phylogenies. While genetic data revealed clear and reproducible differences between this new taxon and all other western Palearctic water frog species including Pelophylax bedriagae in the Levant and two Anatolian water frogs lineages (P. cf. bedriagae -1 and P. cf. bedriagae -2), there is no diagnostic morphological or morphometric character that allows a clear discrimination between Cyprus frogs and frogs from the adjacent mainland. If several morphometric indices are combined as predictor variables in a discriminant analysis, however, both females and males of Cypriot water frogs are correctly distinguished from the other eastern Mediterranean lineages. While phylogenies based on concatenated sequences of two mitochondrial genes (ND2 + ND3) suggest a sister group relationship of Cypriot and Anatolian water frog lineages, our nuclear data hypothesize a sister group relationship between Cypriot frogs (sp. n.) and Crete frogs (P. cretensis), thus speaking for the same isolation time of both island populations.
