Arab Board Anatomic Pathology Part 1 study guide
Arab Board Anatomic Pathology Part 1 · Work through your exam, one topic at a time.
The Arab Board of Health Specializations (ABHS) awards a specialty certification in pathology recognised across much of the Arab world, and Anatomic Pathology Part 1 is the written examination trainees sit early in that programme. It is aimed at residents who have completed a first block of structured histopathology training and are ready to show a working command of the discipline's core knowledge before facing more advanced, subspecialty-heavy assessment. The Arab Board Anatomic Pathology Part 1 study guide has 8 sections and about 2,224 words.
01General Pathology: Cell Injury, Inflammation, Repair, Neoplasia, and Hemodynamics
Cell injury begins with ATP depletion, mitochondrial permeability transition, calcium influx, and reactive oxygen species. Reversible injury shows swelling and blebs; irreversible injury shows membrane rupture, mitochondrial cristae loss, and nuclear changes (pyknosis, karyorrhexis, karyolysis).
320 words, about 2 min02Systemic Pathology by Organ System
Cardiac: atherosclerosis and hypertension dominate; myocardial infarction evolves from coagulative necrosis to granulation tissue to scar. Respiratory: obstructive (asthma, COPD, bronchiectasis) versus restrictive (fibrosis, pneumoconiosis); lung cancer - squamous cell central, adenocarcinoma peripheral, small cell neuroendocrine with paraneoplastic syndromes.

Formal processing: fixation in 10% neutral buffered formalin (volume at least 10 times the tissue), dehydration in graded alcohols, clearing in xylene, embedding in paraffin, sectioning at 3–5 µm, staining with hematoxylin and eosin. Fixation time matters: underfixation causes poor morphology and false-negative immunohistochemistry; overfixation masks antigens.
283 words, about 1 min04Cytopathology: Gynecologic and Non-Gynecologic
The Bethesda system governs reporting: specimen adequacy, interpretation, and recommendations. Categories include negative for intraepithelial lesion or malignancy (NILM), organisms, reactive changes, ASC-US, ASC-H, LSIL, HSIL, squamous cell carcinoma, AGC, and adenocarcinoma.
263 words, about 1 min05Immunohistochemistry and Molecular Pathology
IHC depends on preanalytical factors: fixation time, antigen retrieval, antibody clone, and titration. Always run positive and negative controls.
254 words, about 1 min06Hematopathology and Transfusion-Related Morphology
Start with the CBC: anemia is classified by mean corpuscular volume. Microcytic: iron deficiency, thalassemia, anemia of chronic disease, sideroblastic anemia.
262 words, about 1 min07Autopsy Pathology and Forensic Pathology
Two types: hospital (clinical) autopsy, requiring consent, and medicolegal autopsy, ordered by a legal authority. The autopsy begins with external examination, photography, and documentation, then internal examination with evisceration, organ dissection, and sampling for histology, toxicology, and microbiology.
289 words, about 1 min08Laboratory Management, Quality Assurance, and Biostatistics
Quality has three phases: preanalytical, analytical, and postanalytical. Most errors are preanalytical - mislabeling, wrong tube, hemolysis, delayed transport.
