OMSB Oman Dermatology Exam 2026: Eligibility & MCQs

MOH Oman (OMSB) Dermatology Exam Quick Summary

The OMSB Dermatology specialist exam is a two-stage process: a Pearson VUE-delivered written exam (150 MCQs, roughly 3 hours, 60% passing score), followed by a mandatory viva for candidates who pass the written stage.

MOH Oman (OMSB) Dermatology Specialty Exam

The Oman Medical Specialty Board (OMSB) conducts this specialty exam to assess a dermatologist's knowledge and clinical judgment in diagnosing and managing skin, hair, nail, and mucous membrane conditions, along with dermatologic therapy and surgery. It is required for dermatologists applying for an OMSB professional license to practice in Oman.

Like other OMSB specialist tracks, Dermatology has two stages: the written multiple-choice exam, followed by a mandatory oral viva for candidates who pass it.

Eligibility criteria for the OMSB Dermatology exam

To apply for the OMSB Dermatology specialist exam, candidates are generally expected to meet the following:

Primary medical degree: A recognized MBBS, MD, or equivalent medical degree from an accredited institution.
Specialization in Dermatology: Completion of a residency, Diploma, Master's, or equivalent postgraduate qualification in Dermatology from a recognized institution.
Post-specialization clinical experience: Generally at least 3 years of clinical practice in Dermatology after your specialist qualification -- confirm your own precise requirement directly with OMSB, since this can depend on your specific application track.
Valid license & Good Standing Certificate: An active license to practice in your home country (or country of last employment), plus a Certificate of Good Standing typically valid within the last 6 months.
DataFlow Primary Source Verification: All educational, professional, and licensing documents verified through DataFlow. See the full OMSB general eligibility requirements for the complete document checklist.

Confirm your own eligibility status directly with OMSB rather than assuming a general figure applies to you.

OMSB Dermatology exam exemption criteria

Possible exam exemption
Dermatologists holding a recognized international fellowship or board certification -- such as the American Board of Dermatology or a UK CCT in Dermatology -- may be considered for an exemption from the written exam. OMSB does not publish a fixed list of qualifying certifications the way some other Gulf authorities do, and each case is evaluated individually with supporting documentation. Confirm your own exemption status directly with OMSB before assuming any specific certification qualifies.

OMSB Dermatology exam syllabus

The exam draws from the following subject areas, reflecting the discipline of dermatology itself:

  • Basic science and embryology
  • Dermatopathology (including staining techniques)
  • Pruritus and papulosquamous dermatoses
  • Urticaria, erythemas, and purpuras
  • Vesiculobullous diseases
  • Adnexal, hair, nail, and mucous membrane diseases
  • Allergy and immunology
  • Metabolic, rheumatologic, and systemic diseases
  • Genodermatoses and pigmentary disorders
  • Clinical infectious disease, infestations, and bites
  • Disorders due to physical agents
  • Vascular disorders and neoplasms of the skin (benign and malignant)
  • Dermatological therapy
  • Dermatological surgery and cosmetology

Most questions are presented as clinical scenario-based MCQs, with many drawing on clinical images rather than text descriptions alone.

Passing score (written)

Passing the written exam is not the final step: candidates must then complete a mandatory viva, using case scenarios relevant to dermatology. The exact question count, duration, and passing score can differ from DHA, DOH, and other Gulf authorities' versions of this specialty exam -- always confirm the OMSB-specific figures directly with OMSB.

Preparation tips for the OMSB Dermatology exam

Study clinical images actively
Many questions are image-based -- practice recognizing lesion morphology, distribution patterns, and classic presentations, not just reading descriptions.
Prepare for the viva separately
The viva tests case-based clinical reasoning verbally -- practice explaining your diagnosis and treatment plan out loud, not just recognizing the right MCQ answer.
Prioritize high-yield disease groups
Papulosquamous disorders, vesiculobullous diseases, and skin neoplasms are consistently well represented.
Know first-line therapy
Be precise on standard treatment protocols and drug classes for common dermatoses -- therapy questions are frequent.

Sample Practice MCQs

Test your knowledge with these original clinical scenario-style questions. Tap a question to reveal the answer.

> Question 1: Papulosquamous Disease
A patient presents with well-demarcated, silvery-scaled erythematous plaques on the extensor surfaces of both elbows and knees. What is the most likely diagnosis?

Answer: Plaque psoriasis.

Explanation: Silvery scale on well-demarcated erythematous plaques over extensor surfaces (elbows, knees) is the classic presentation of chronic plaque psoriasis.
> Question 2: Infectious Disease
A patient presents with an annular, scaly, erythematous plaque with a central clearing and an active raised border on the trunk. Potassium hydroxide (KOH) prep of the active border shows branching hyphae. What is the most likely diagnosis?

Answer: Tinea corporis.

Explanation: An annular plaque with central clearing and an active scaly border, confirmed by branching hyphae on KOH prep taken from the active edge, is the classic presentation and diagnostic approach for tinea corporis (dermatophyte infection).
> Question 3: Vascular Disorders & Neoplasms
A pigmented skin lesion shows asymmetry, irregular borders, color variation, a diameter over 6mm, and recent evolution in size. What is the most appropriate next step?

Answer: Excisional biopsy for histopathological evaluation.

Explanation: The ABCDE criteria (Asymmetry, Border irregularity, Color variation, Diameter greater than 6mm, Evolution) raise suspicion for melanoma, warranting prompt excisional biopsy rather than watchful waiting.
