Abstract Infective, granulomatous and benign histiocytic disorders are only rarely an indication for bone marrow (BM) examination and therefore often represent unexpected or incidental findings. Yet since they are frequently…
Abstract Bone marrow (BM) hyperplasia, a non-neoplastic expansion of one or more of the haematopoietic cell lineages due to an increased number of cells, can manifest in a range of…
Abstract The myelodysplastic/myeloproliferative neoplasms (MDS/MPN) are clonal myeloid neoplasms characterized at the time of their initial presentation by the simultaneous presence of myelodysplastic and myeloproliferative features, which prevent them from…
Abstract Acute myeloid leukaemia (AML) is a highly complex and heterogeneous disease. Proper classification according to the 2016 World Health Organization (WHO) classification requires a systematic approach and integration of…
Abstract Myelodysplastic syndromes (MDS) comprise a heterogeneous group of myeloid neoplasms defined by peripheral cytopaenia, morphologic dysplasia in one or more haematopoietic lineages, and genetic instability with risk of transformation…
Abstract The ‘classical’ Philadelphia chromosome-negative myeloproliferative neoplasms (MPN), essential thrombocythaemia (ET), primary myelofibrosis (PMF) and polycythaemia vera (PV), are characterized by clonal myeloproliferation with effective maturation causing accumulation of terminally…
Abstract Disorders of histiocytic and dendritic cell origin, traditionally referred to as histiocytoses [1], form a group of extremely rare tumours, characterized by variable malignant potential and unpredictable clinical course,…
Abstract The bone marrow (BM) extracellular matrix (ECM) is often inconspicuous, and hence neglected in a normal BM trephine biopsy (BMB), but it has essential functions in the homeostasis of…
Abstract Aplasia is a pathologic term that is broadly defined as the absence or near-absence of one or more haematopoietic lineages in the bone marrow (BM). Clinically, BM aplasia affecting…
Abstract Trepanning of the bone is one of the oldest known procedures carried out by man and the use of the modern trephine biopsy has a venerable history. Parapia has…
