Sample Arab Board Anatomic Pathology Part 1 Practice Questions
Try these sample questions to review concepts for the Arab Board Anatomic Pathology Part 1 exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.
1A 58-year-old man dies following an acute myocardial infarction. Histological examination of the left ventricular myocardium demonstrates preserved basic cellular architecture with loss of nuclei and intensely eosinophilic cytoplasm. What type of necrosis is most characteristic of this lesion?
2A 64-year-old woman with a history of atrial fibrillation suffers an embolic stroke affecting the right middle cerebral artery territory. Three weeks later, autopsy reveals a cystic cavity filled with fluid and cellular debris in the temporal lobe. Which mechanism explains this necrosis pattern?
3A lung biopsy from a 32-year-old immigrant with chronic cough, hemoptysis, and night sweats shows granulomas composed of epithelioid histiocytes and Langhans giant cells surrounding a central acellular, granular, eosinophilic core devoid of tissue architecture. What is the most likely diagnosis?
4A 45-year-old man develops severe epigastric pain radiating to the back following heavy alcohol consumption. Laparotomy reveals chalky-white, firm deposits scattered across the omental fat. Histologically, there are shadowy outlines of necrotic adipocytes with basophilic calcium deposits. What chemical process produced these gross findings?
5A 35-year-old woman with systemic lupus erythematosus presents with accelerated hypertension, hematuria, and renal failure. Renal biopsy demonstrates circumferential, intensely eosinophilic, smudgy, refractive material expanding the walls of afferent arterioles with nuclear fragments (karyorrhexis). What is the identity of this histological pattern?
6During the intrinsic (mitochondrial) pathway of apoptosis, which molecular event directly initiates the formation of the apoptosome complex in the cytosol?
7Cytotoxic T lymphocytes eliminate virus-infected cells and neoplastic targets through death receptor signaling. Which initiator caspase is directly recruited and activated by the death-inducing signaling complex (DISC) following FasL binding to Fas (CD95)?
8Which combination correctly groups the BCL2 family proteins into their respective functional categories regarding mitochondrial membrane permeability?
9A researcher is studying the molecular machinery of autophagy during nutrient deprivation in human hepatoma cell lines. Which protein is lipidated with phosphatidylethanolamine to form a membrane-bound marker essential for autophagosome elongation and closure?
10A 60-year-old man undergoes successful emergency percutaneous coronary intervention for an acute anterior myocardial infarction. However, shortly after stent placement, serial cardiac biomarker levels spike dramatically and transient arrhythmias occur. What pathophysiological mechanism is primarily responsible for ischemia-reperfusion injury?
About the Arab Board Anatomic Pathology Part 1 Exam
The Arab Board Anatomic Pathology Part 1 written examination is taken during the early phase of pathology residency across Arab League member states. It assesses foundational knowledge across general pathology, cell biology, mechanisms of disease, hemodynamic disorders, neoplasia, immunopathology, infectious disease histology, genetic disorders, forensic/autopsy pathology, and diagnostic histotechnology.
Exam sponsor: Arab Board of Health Specializations (ABHS) - Scientific Council of Pathology. The requirements and fees below concern the certification or admission exam, separate from our free practice resources.
Assessment
A single computer-based written paper of best-of-four single-best-answer multiple-choice questions, frequently presented as clinical and diagnostic vignettes assessing fundamental general pathology, pathophysiology, and laboratory principles.
Time Limit
Approximately 2.5 to 3 hours
Passing Score
60%, per the ABHS examination-affairs decisions, which fix the pass mark at 60% in the primary written, final written and clinical/oral examinations of every scientific council. Recent council guidebooks add that the mark is confirmed by criterion-referenced standard setting under the Arab Board bylaws.
Exam / Certification Fees
Set by ABHS and national training councils across member states; fees change periodically, so candidates should confirm amounts locally.
Exam sponsor websiteFees, eligibility, and exam policies can change. Confirm them with the exam sponsor before applying or paying.

Infectious Diseases and Diagnostic Special Stains
Histopathological patterns of infection (suppurative, mononuclear, cytopathic-cytoproliferative, necrotizing, chronic/scarring), viral inclusions, opportunistic mycoses, and application of histochemical special stains.
Genetic, Developmental, and Pediatric Pathology
Mendelian inheritance patterns, cytogenetic aneuploidies and translocations, trinucleotide repeat disorders, lysosomal storage diseases, neonatal respiratory distress, and pediatric small round blue cell neoplasms.

Arab Board Anatomic Pathology Part 1: Suggested Study Strategy
Frequently Asked Questions
What is the structure of the Arab Board Anatomic Pathology Part 1 exam?
The Part 1 exam is a computer-based written examination comprising 100 single-best-answer multiple-choice questions (best of 4 options), completed in approximately 2.5 to 3 hours. It focuses heavily on general pathology, cellular and molecular mechanisms of disease, and laboratory histotechnology.
What is the passing score for the Arab Board Anatomic Pathology Part 1 exam?
The pass mark is commonly reported as approximately 60% by candidates across regional training centers. Because the Arab Board of Health Specializations (ABHS) and national committees may apply criterion-referenced standard setting, candidates should verify specific passing requirements with their local council.
When is the Arab Board Anatomic Pathology Part 1 examination taken?
Residency candidates typically sit for the Part 1 written examination at the end of their first or second year of postgraduate pathology residency training, after fulfilling foundational rotations in surgical pathology, histotechnology, and autopsy pathology.
How does Part 1 differ from the Part 2 (Final) Arab Board Pathology Examination?
Part 1 emphasizes foundational general pathology, disease mechanisms, basic immunopathology, genetic disorders, and laboratory techniques. Part 2 (Exit Examination) focuses on comprehensive systemic surgical pathology, virtual and glass slide diagnostic practicals, cytopathology, gross specimen evaluation, and oral/OSCE clinical case management.
