Top 10 Questions for Histopathologist Interview

1. How would you approach the diagnosis of a small round blue cell tumor?

• Histologic features: evaluate size, shape, and chromatin pattern of the cells, as well as the presence of rosettes, Homer-Wright rosettes, or other characteristic features.
• Immunohistochemistry: use a panel of antibodies to differentiate between different types of small round blue cell tumors, such as lymphoma, neuroblastoma, and Ewing sarcoma.
• Molecular studies: perform molecular testing, such as FISH or PCR, to identify specific genetic alterations that can help in the diagnosis.
• Clinical history and imaging studies: consider the patient’s age, symptoms, and imaging findings to narrow down the differential diagnosis.

2. What are the key microscopic features that distinguish between squamous cell carcinoma and basal cell carcinoma?

Microscopic features of squamous cell carcinoma:

• Intercellular bridges
• Keratin pearls
• Dyskeratotic cells

Microscopic features of basal cell carcinoma:

• Peripheral palisading of basaloid cells
• Retraction artifacts
• Cystic change

3. How would you assess the adequacy of a biopsy specimen for the diagnosis of an infectious disease?

• Evaluate the size and depth of the biopsy specimen.
• Assess the cellularity and presence of inflammatory cells.
• Identify the presence of the suspected infectious agent using appropriate stains or molecular techniques.
• Consider the clinical history and imaging findings to determine if the biopsy is likely to be representative of the underlying pathology.

4. What are the different types of melanocytic nevi, and how do you differentiate between them?

• Junctional nevus: Nevus cells are located at the dermal-epidermal junction.
• Compound nevus: Nevus cells are present in both the dermis and epidermis.
• Intradermal nevus: Nevus cells are located solely in the dermis.
• Dysplastic nevus: Atypical melanocytic nevus that has some features of melanoma, such as architectural disarray and pleomorphic nuclei. Diffuse atypia with melanocytes extending beyond the rete ridges.
• Blue nevus: Nevus cells contain melanin with a bluish hue.

5. How would you approach the diagnosis of a soft tissue sarcoma?

• Histologic features: assess the cellularity, architecture, and presence of specific histologic patterns.
• Immunohistochemistry: use a panel of antibodies to differentiate between different types of soft tissue sarcomas, such as leiomyosarcoma, liposarcoma, and synovial sarcoma.
• Molecular studies: perform molecular testing, such as FISH or PCR, to identify specific genetic alterations that can help in the diagnosis.
• Clinical history and imaging studies: consider the patient’s age, symptoms, and imaging findings to narrow down the differential diagnosis.

6. What are the different types of grading systems used for breast cancer, and how do they compare?

• Bloom-Richardson grading system: Based on tubule formation, nuclear grade, and mitotic count.
• Nottingham grading system: Similar to the Bloom-Richardson system, but also includes tumor size and lymphatic invasion.
• Scarff-Bloom-Richardson grading system: Focuses on nuclear grade and mitotic count.
• Elston-Ellis grading system: Assesses tumor size, nodal status, and histologic grade.

7. How would you assess the severity of chronic hepatitis?

• Histologic features: Grade the degree of inflammation, fibrosis, and necrosis.
• Immunohistochemistry: Assess the expression of specific markers, such as hepatitis B surface antigen or hepatitis C virus RNA, to determine the etiology of the hepatitis.
• Clinical history and laboratory tests: Consider the patient’s symptoms, liver function tests, and viral load to assess the severity of the disease.

8. What are the different types of amyloid, and how do you differentiate between them?

• AL amyloid: Derived from immunoglobulin light chains.
• AA amyloid: Derived from serum amyloid A protein.
• ATTR amyloid: Derived from transthyretin.
• Aβ amyloid: Derived from amyloid beta protein.
• PrP amyloid: Derived from prion protein.

9. How would you approach the diagnosis of a renal biopsy?

• Light microscopy: Assess the glomerular, tubular, and interstitial compartments for abnormalities.
• Immunofluorescence: Use antibodies to identify specific proteins, such as immunoglobulins or complement components, to help determine the etiology of the renal disease.
• Electron microscopy: Provides ultrastructural details that can help in the diagnosis of certain renal diseases, such as minimal change disease or membranous nephropathy.
• Clinical history and laboratory tests: Consider the patient’s symptoms, urine analysis, and blood tests to narrow down the differential diagnosis.

10. What are the different types of immunofluorescence patterns seen in glomerulonephritis, and what do they indicate?

• Granular pattern: Deposition of immune complexes in the glomerulus, seen in diseases such as lupus nephritis and post-infectious glomerulonephritis.
• Linear pattern: Deposition of antibodies along the glomerular basement membrane, seen in diseases such as Goodpasture’s syndrome and anti-GBM disease.
• Mesangial pattern: Deposition of immune complexes in the mesangium, seen in diseases such as IgA nephropathy and diabetic nephropathy.
• Membranous pattern: Deposition of antibodies along the glomerular capillary walls, seen in diseases such as membranous nephropathy.

Histopathologists are medical professionals who diagnose and study diseases of the tissues. They play a critical role in healthcare by providing essential information to clinicians for patient care and treatment planning.

1. Tissue Examination and Analysis

Examining and analyzing tissue samples under a microscope to identify abnormal cells and structures.

• Performing biopsies and preparing tissue samples for examination.
• Using various staining techniques to highlight specific tissue components.

2. Diagnosis and Reporting

Diagnosing diseases based on the microscopic examination of tissue samples and providing detailed reports to clinicians.

• Identifying and classifying different types of diseases, such as cancer, infections, and autoimmune disorders.
• Documenting findings in medical records and issuing reports that include diagnoses, prognoses, and recommendations for treatment.

3. Consultation and Collaboration

Consulting with clinicians, surgeons, and other healthcare professionals to discuss patient cases and provide expert opinions.

• Providing guidance on the interpretation of test results and recommending follow-up procedures.
• Participating in multidisciplinary teams to develop and implement treatment plans.

4. Research and Development

Conducting research to improve diagnostic techniques and advance the field of histopathology.

• Developing new staining methods and molecular assays.
• Investigating the relationship between tissue changes and disease progression.

Preparing for a histopathologist interview requires a combination of technical knowledge, communication skills, and professional demeanor. Here are some tips to help you ace your interview:

1. Research the Position and Organization

Familiarize yourself with the specific job requirements and the organization’s mission and values.
