26. A 19-year-old male presents with painless enlargement of cervical lymph nodes. Biopsy of a node shows a mixed inflammatory background composed of lymphocytes, plasma cells, eosinophils, and classic Reed-Sternberg cells (large binucleated cells with prominent owl-eye nucleoli). Immunohistochemistry demonstrates positivity for CD15 and CD30. What is the diagnosis?
A. Non-Hodgkin lymphoma
B. Classic Hodgkin lymphoma
C. Infectious mononucleosis
D. Reactive lymphoid hyperplasia
27. A 45-year-old male with long-standing heartburn presents for endoscopic evaluation of gastroesophageal reflux disease. Biopsy from the lower esophagus just proximal to the gastroesophageal junction reveals replacement of normal stratified squamous epithelium by columnar epithelium with goblet cells (intestinal metaplasia). What is the underlying condition?
A. Squamous cell carcinoma
B. Achalasia cardia
C. Esophageal varices
D. Barrett esophagus
28. A 60-year-old male undergoes routine screening colonoscopy, which reveals a 1.5 cm pedunculated polyp in the sigmoid colon. Microscopic evaluation demonstrates branching tubule-glandular structures lined by dysplastic, hyperchromatic columnar epithelium without invasion of the muscularis mucosae. What is the diagnosis?
A. Hyperplastic polyp
B. Juvenile polyp
C. Tubular adenoma
D. Adenocarcinoma | 596 |
| 20 | 14. A 70-year-old male presents with progressive urinary hesitancy, poor stream, post-void dribbling, and nocturia for the past year. Digital rectal examination reveals a smooth, symmetrically enlarged, firm-elastic prostate without distinct nodules. Transrectal ultrasound confirms significant enlargement of the transition zone. Transurethral resection shows hyperplasia of both glandular epithelial elements and fibromuscular stroma without cellular atypia. What is the diagnosis?
A. Prostatic adenocarcinoma
B. Acute bacterial prostatitis
C. Benign prostatic hyperplasia
D. Nodular fasciitis
15. A 40-year-old female presents with a 3-month history of progressive muscle weakness, particularly difficulty rising from a chair and climbing stairs. She also notices a heliotrope rash over her upper eyelids and Gottron papules on her knuckles. Creatine kinase levels are significantly elevated. Muscle biopsy reveals prominent inflammatory infiltrates predominantly localized in the perimysial regions and around blood vessels, along with perifascicular atrophy. What is the diagnosis?
A. Polymyositis
B. Dermatomyositis
C. Inclusion body myositis
D. Myasthenia gravis
16. A 58-year-old male presents with severe retrosternal chest pain radiating to his left arm and jaw, lasting for over 2 hours. Troponin I levels are elevated. Unfortunately, the patient suffers a fatal cardiac arrhythmia 3 days after admission. Autopsy of the heart reveals a pale yellow, softened area of myocardium surrounded by a hyperemic border. Microscopic examination of this area would most likely demonstrate which feature?
A. Dense collagenous scar tissue
B. Contraction band necrosis with early edema
C. Abundant granulation tissue with capillary proliferation
D. Coagulative necrosis with dense neutrophilic infiltrate
17. A 30-year-old male presents with recurrent episodes of gross hematuria that consistently occur 1–2 days after upper respiratory tract infections. He reports no fever, joint pain, or rash. Physical examination is unremarkable, and blood pressure is normal. Urinalysis demonstrates mild proteinuria and dysmorphic red cells. Renal biopsy with immunofluorescence displays granular immunofluorescent deposition predominantly located within the glomerular mesangium. What is the diagnosis?
A. IgA nephropathy
B. Post-streptococcal glomerulonephritis
C. Goodpasture syndrome
D. Alport syndrome
18. A 14-year-old boy presents with severe bleeding following a minor tooth extraction. He has a history of recurrent hemarthroses in his knees and elbows. Laboratory tests show a prolonged activated partial thromboplastin time (aPTT) that corrects fully upon 1:1 mixing with normal plasma, while prothrombin time (PT), bleeding time, and platelet count are normal. Factor VIII activity is found to be 2% of normal. What is the underlying pathology?
A. Factor IX deficiency
B. von Willebrand disease
C. Factor VIII deficiency
D. Factor XI deficiency
19. A 60-year-old male complains of deep bone pain in his back and ribs, easy fatigability, and recurrent bacterial infections. Laboratory evaluation reveals normocytic anemia, hypercalcemia, elevated serum creatinine, and a monoclonal spike (M-protein) on serum protein electrophoresis. Urine testing shows Bence-Jones proteins. Bone marrow aspirate reveals >30% clonal plasma cells with eccentric nuclei and clock-face chromatin. What is the diagnosis?
A. Monoclonal gammopathy of undetermined significance
B. Waldenström macroglobulinemia
C. Hodgkin lymphoma
D. Multiple myeloma
20. A 25-year-old female presents with fatigue and pallor. Her peripheral blood smear shows microspherocytes, hyperchromic cells, and polychromasia. Osmotic fragility testing reveals increased fragility of red blood cells when incubated in hypotonic saline solutions. The patient's underlying defect is a mutation in spectrin or ankyrin proteins. What is the primary inherited condition?
A. Hereditary spherocytosis
B. Glucose-6-phosphate dehydrogenase deficiency
C. Sickle cell anemia
D. Beta-thalassemia major | 447 |
