What is Cases in Hematology for the MLA and PLAB?
Cases in Hematology for the MLA and PLAB by Aaron Niblock is a case-based haematology revision book built around single best answer questions. It covers conditions mapped to the Medical Licensing Assessment and provides explanations of the underlying physiological principles, making it useful for medical students preparing for qualifying examinations.
Introduction
Haematology is a subject in which clinical presentation, laboratory interpretation, pathophysiology and pharmacology are closely connected.
For students preparing for medical licensing examinations, simply memorising disease names and laboratory values is rarely enough. The ability to interpret a clinical scenario and identify the most appropriate diagnosis, investigation or management step is equally important.
Cases in Hematology for the MLA and PLAB by Aaron Niblock takes a deliberately case-based approach to this challenge. Published by CRC Press in 2025 as part of the MasterPass series, the book uses single best answer-style questions to explore haematological presentations and conditions included in the Medical Licensing Assessment (MLA) content map.
The book is primarily aimed at medical students preparing for qualifying examinations, particularly those working toward the MLA, while its case-based format can also support learners who want to consolidate haematology knowledge during their clinical years.
Rather than presenting haematology as a conventional narrative textbook, Aaron Niblock organizes learning around clinical problems. A question is presented first, followed by an explanation of the answer and the physiological principles needed to understand why that answer is appropriate. The book then concludes with an additional "Test Yourself" section designed to assess knowledge gained from the preceding cases.

WHAT THIS BOOK COVERS
The central focus of Cases in Hematology for the MLA and PLAB is clinical haematology presented through single best answer questions. The contents are divided into clinical cases, transfusion medicine, malignant haematology, laboratory haematology science, and an additional self-assessment section.
The opening clinical material covers benign haematology. Topics include iron deficiency anaemia, thalassaemia, vitamin B12 deficiency, pancytopenia, sickle cell disease, polycythaemia, hyposplenism, haemophilia A, von Willebrand disease, disseminated intravascular coagulation, thrombotic thrombocytopenic purpura, haemolysis, immune thrombocytopenia, warfarin, direct oral anticoagulants, haemochromatosis, deep venous thrombosis, pulmonary embolism and arterial thrombosis.
The cases are designed to connect clinical information with laboratory findings. For example, the anaemia material uses haemoglobin, MCV and MCH to establish the classification of anaemia before discussing possible causes. The explanation then connects red-cell size with iron, globin, vitamin B12 and folate physiology.
The book also gives attention to haemoglobinopathies. Its thalassaemia case uses the timing of presentation and haemoglobin-chain development to distinguish beta-chain abnormalities from severe alpha-chain disorders.
Sickle cell disease is approached through clinical presentation and complications. The case involving hypoxia, fever and pulmonary infiltrates introduces acute chest crisis and discusses the relationship between sickling, vaso-occlusion and triggers such as hypoxia, dehydration and infection.
The coagulation section similarly emphasizes pattern recognition. An isolated prolonged APTT, for example, is used to narrow the differential toward factor deficiencies such as haemophilia A, haemophilia B and factor XI deficiency. The discussion also highlights that factor XIII is not assessed by the standard in-vitro coagulation screen.
Transfusion Medicine
A dedicated section addresses practical transfusion medicine. The contents include:
- Massive haemorrhage
- Post-partum haemorrhage
- Transfusion-associated circulatory overload (TACO)
- Transfusion-related acute lung injury (TRALI)
- Non-haemolytic transfusion reactions
- Acute haemolytic transfusion reactions
- Chronic haemolytic transfusion reactions
The cases place transfusion decisions within clinical scenarios. For example, the massive-haemorrhage case asks the learner to interpret post-resuscitation coagulation results and identify the appropriate blood product based on fibrinogen levels. The post-partum haemorrhage case similarly requires interpretation of coagulation and fibrinogen results.
The TACO case illustrates the same case-based philosophy: the reader must distinguish a transfusion complication from other causes of acute dyspnoea by integrating timing, oxygen saturation and examination findings such as elevated JVP and pulmonary crepitations.
Malignant Haematology
The malignant haematology section covers a broad range of important blood cancers and related clinical presentations.
Included conditions are:
- Acute lymphoblastic leukaemia (ALL)
- Acute myeloid leukaemia (AML)
- Acute promyelocytic leukaemia (APL/APML)
- Chronic myeloid leukaemia (CML)
- Chronic lymphocytic leukaemia (CLL)
- Essential thrombocytosis
- Polycythaemia rubra vera
- Primary myelofibrosis
- Plasma cell myeloma
- Pathological fracture
- Hodgkin lymphoma
- Non-Hodgkin lymphoma
- Neutropenic sepsis
- Superior vena cava obstruction
- Myelodysplasia
Several cases emphasize the diagnostic significance of specific laboratory or molecular findings. The AML material, for example, uses blasts and Auer rods to establish myeloid lineage, while the APL case incorporates the t(15;17) genetic abnormality and associated coagulation abnormalities.
The CML case introduces the Philadelphia chromosome and BCR-ABL as central diagnostic and therapeutic concepts. The explanation also connects the acquired genetic abnormality with targeted tyrosine kinase inhibitor therapy.
The myeloma cases address paraprotein production, clonal plasma cells, organ or tissue impairment, and lytic bone lesions. The book specifically discusses the CRAB framework and the distinction between symptomatic myeloma, smouldering myeloma, and MGUS.
Laboratory Haematology Science
The later cases shift toward laboratory science and mechanisms that can be overlooked when studying only clinical presentations.
The listed topics include:
- Platelet clumping
- Cold agglutinins
- Cryoglobulins
- Methaemoglobin
- Methotrexate and folate metabolism
- G6PD deficiency and the pentose phosphate pathway
This section reinforces an important examination skill: recognizing when a laboratory result may require interpretation rather than immediate acceptance. The platelet-clumping case, for example, explains EDTA-dependent pseudothrombocytopenia and the use of an alternative anticoagulant such as sodium citrate when confirmation is needed.
Key Features
- Single best answer format: The book uses SBA-style questions throughout its principal clinical cases.
- Case-based learning: Clinical scenarios require the reader to apply haematology knowledge rather than simply recall isolated facts.
- Answer explanations: Questions are followed by explanations of relevant physiological principles.
- MLA-focused content: The book covers haematology presentations and conditions listed in the MLA content map.
- Broad specialty coverage: The material extends from anaemia and haemostasis to transfusion medicine, leukaemia, lymphoma, myeloma and laboratory science.
- Dedicated self-assessment: Part II contains additional Test Yourself questions and answers.
- Clinical interpretation: Many cases combine symptoms, examination findings, blood counts, coagulation results, blood films and molecular findings.
- Physiology alongside diagnosis: Explanations frequently move beyond the correct option to explain the mechanism behind it.
- Illustrations: The acknowledgements state that the illustrations throughout the book were created by Evie.
Who Should Read This Book?
Medical Students
Medical students are the clearest target audience. The book was specifically designed around haematology presentations and conditions included in the MLA content map and describes itself as suitable for students working toward qualifying examinations.
It can be particularly useful after an initial pass through haematology, when the learner needs to convert theoretical knowledge into clinical decision-making.
Residents and Interns
Junior doctors can use the cases to revise fundamental haematology while developing familiarity with common laboratory patterns. The case format makes the material suitable for short revision sessions rather than requiring a continuous textbook-reading session.
Specialists
The book is not presented as an advanced specialist reference. However, individual cases may be useful for teaching, undergraduate supervision or rapid revision of fundamental haematological principles.
Exam Candidates
MLA candidates are a particularly relevant audience because the book's structure and content were specifically developed around the MLA. The inclusion of an additional Test Yourself section provides another opportunity for self-assessment after studying the clinical cases.
Why This Book is Useful
Clinical Relevance
A major educational advantage of case-based revision is that clinical findings are presented in context. Instead of studying "TTP," "DIC," or "haemophilia" as isolated topics, the learner encounters patients with symptoms, examination findings and laboratory abnormalities.
This approach is evident throughout the book. A patient with thrombocytopenia and schistocytes, for example, requires the reader to distinguish TTP from other causes of microangiopathic haemolytic anaemia by interpreting the overall clinical picture.
Evidence-Based Learning
The book's educational explanations are built around physiological and clinical principles. Its preface specifically states that the answers explain key physiological principles so readers can use the knowledge to answer similarly styled questions.
The book itself also cautions that rapidly changing information concerning dosages, procedures,s and diagnoses should be independently verified against appropriate current guidance and formularies.
Practical Application
The questions frequently ask for the next investigation, diagnosis, immediate intervention or management decision. This makes the material particularly relevant to clinical reasoning.
Examples include identifying the appropriate investigation for suspected von Willebrand disease, distinguishing transfusion reactions, interpreting an isolated prolonged coagulation result, and recognizing acute haematological emergencies.
Board and Licensing Examination Usefulness
The book's design is explicitly aligned with the MLA rather than being a general haematology textbook. Its SBA structure, clinical cases, and final Test Yourself section make it suitable for examination-focused revision. The exact degree of usefulness for any particular PLAB candidate cannot be established from the book alone, although the title explicitly includes PLAB.
Learning Efficiency
The question-answer-explanation format allows readers to identify gaps in knowledge quickly. A useful revision cycle is to attempt the question before reading the explanation, identify the reasoning that led to the correct answer, and then revisit the underlying physiological principle.
Table of Contents Overview
The book contains two major parts.
Part I – Clinical Cases includes four sections:
- Benign Haematology — Cases 1–19
- Transfusion Medicine — Cases 20–26
- Malignant Haematology — Cases 27–41
- Laboratory Haematology Science — Cases 42–47
The contents list specific topics ranging from iron deficiency anaemia and haemoglobinopathies to leukaemias, lymphomas, plasma cell myeloma, transfusion complications and laboratory abnormalities.
Part II – Additional Test Yourself Questions and Answers begins with a Test Yourself section and concludes with the corresponding answers. The contents indicate 25 numbered Test Yourself questions.
The book also includes a preface, acknowledgements, author biography, abbreviation list, MLA conditions and an index.
Strengths of The Book
One of the clearest strengths of Cases in Haematology for the MLA and PLAB is its focused structure. It does not attempt to function as an encyclopedic haematology reference. Instead, it concentrates on applying core knowledge to clinical questions.
The organization also provides useful breadth. The reader moves from common problems such as anaemia and anticoagulation through haemoglobinopathies, bleeding disorders and thrombosis before progressing to transfusion medicine, malignant haematology and laboratory science.
Another strength is the explanatory material following the answers. In several cases, the explanation addresses why the correct answer fits and why alternative diagnoses are less appropriate. This is particularly valuable for learners who struggle with questions requiring discrimination between conditions with overlapping presentations.
The book also has a strong laboratory component. Blood counts, MCV, coagulation studies, blood films, biochemical markers and molecular findings appear repeatedly, reinforcing the relationship between clinical assessment and laboratory interpretation.
Finally, the additional Test Yourself section allows readers to move from guided learning to independent assessment.
Limitations
The book's focused examination orientation is also its principal limitation as a standalone reference. It is designed around single best answer questions rather than comprehensive coverage of every aspect of clinical haematology.
The book emphasizes that medical information can change and that clinical decisions, dosages and procedures should be independently verified against current professional guidance. Therefore, it should be regarded as a revision and educational resource rather than a substitute for current clinical guidelines, formularies or specialist references.
Comparison With Similar Books
Cases in Hematology for the MLA and PLAB is identifiable as part of the MasterPass series, which contains other examination-focused resources covering specialties and examination formats such as neurosurgery, sport and exercise medicine, clinical consultation skills, anaesthesia, intensive care and ophthalmology.
The book therefore occupies a specific niche: case-based haematology revision for licensing and qualifying examinations.
It differs in emphasis from a traditional comprehensive haematology textbook because its primary unit of learning is the clinical question. It also differs from a purely question-bank approach because the answers contain explanatory discussion of physiological principles rather than providing only the correct option.
