Test your dermatology knowledge with JAMA Network clinical challenges

Online continuing medical education (CME) isn’t just convenient; it can be hugely additive to a physician’s knowledge of their specialty.

JN Learning™, the CME arm of the JAMA Network™, enables users to browse the JAMA Network catalogue of over 5,000 online resources by any medical topic. A filter then lets users locate more than 1,700 relevant online CME opportunities.

CME from the JAMA Network enables you to earn AMA PRA Category 1 CME Credit™ from a source you trust. The AMA has added lessons for many of the most common specialty health topics.

The dermatology category helps learners correctly diagnose and treat unusual presentations of skin cancer, atopic dermatitis, psoriasis, skin lymphomas, cutaneous drug reactions and more. The 10-lesson online series covers the following topics.

1. "Progressive Skin Depressions in a Child’s Neck."

   1. A two-year-old girl who was otherwise healthy presented with a 10-month history of asymptomatic skin depressions in her neck, nape and submandibular regions. The lesion initially occurred as an erythema in the neck and progressed centrifugally to the nape and submandibular areas. What is your diagnosis?

2. "Urticaria 12 Days After COVID-19 mRNA Booster Vaccination."

   1. A healthy 27-year-old woman received a COVID-19 mRNA booster vaccine (Moderna) on December 7, 2021. She had not experienced adverse effects after the first two vaccine doses on Jan. 17 and Feb. 5, 2021. Twelve days after the booster vaccination, she developed pruritic wheals on her face and bilateral, transient eyelid swelling. Over the next week, a pruritic rash spread over her neck, chest, trunk and arms; each lesion faded without scarring within 24 hours. What would you do next?

3. "Necrotic Plaques on the Ears of a Patient With COVID-19."

   1. A man in his 40s with a medical history of factor VII deficiency hemophilia presented with acute hypoxic respiratory failure secondary to COVID-19. Following admission, he was intubated with prone positioning, and treatment with tocilizumab and dexamethasone was started. He was also found to have Staphylococcus hemolyticus bacteremia, and treatment with cefepime was initiated. Three days after admission, the patient developed erythema and edematous necrotic plaques of the bilateral ears. What is your diagnosis?

4. "Generalized Micropapular Eruption in a Teenager."

   1. A teenage boy presented to the outpatient clinic with a one-year history of asymptomatic cutaneous lesions on the face that had progressively spread to the trunk and extremities. He also had asthenia and mild intermittent arthralgias. What is your diagnosis?

5. "Excessive Wrinkling on the Dorsum of the Hands and Wrists."

   1. An otherwise healthy man in his 20s presented to the dermatology department with thickening and swelling of hands after immersion in water, accompanied by burning pruritus for three years. The lesions occurred as symmetrical white and transparent papules, white keratosis, excessive wrinkling on the dorsum of hands after water immersion and worsened in summer, and remitted in winter. What is your diagnosis?

6. "Recurrent Photosensitive Pustular Eruption in a Young Woman."

   1. A woman in her 20s was referred for evaluation of a four-year history of recurrent pustular eruptions on her face, which initially presented while she was vacationing in Florida. She noted mild associated pruritus but denied burning sensation. The eruptions occurred intermittently, appearing as erythematous papules with prominent pustules, and were exacerbated by sunlight. What is your diagnosis?

7. "Multiple Craniofacial Nodules and Plaques Distributed Bilaterally Along Blaschko Lines."

   1. A male in his late teens presented with asymptomatic congenital papules, plaques and nodules in a linear bilateral distribution following Blaschko lines on the scalp and face region. The papules and nodules appeared to grow as the boy grew, and some pedunculated lesions tended to fall off spontaneously. What is your diagnosis?

8. "Violaceous Plaques on the Left Lower Extremity."

   1. A young man presented to the clinic with large, purple plaques on the left lower extremity. The plaques had been present for years, but the patient noted enlargement and darkening for the past five years. What is your diagnosis?

9. "Oral Lichenoid Lesions Associated With Mediastinal Mass and Hypogammaglobulinemia in a Middle-aged Man."

   1. A white man in his 50s with a clinical history of recurrent respiratory infections and diarrhea presented with painful oral erosions that began two years before. Results of a previous intestinal biopsy had shown unspecific findings and absence of apoptosis. What is your diagnosis?

10. "Blue Pigmentation of the Skin, Sclera and Teeth."

    1. A 69-year-old man presented with a one-month history of progressive skin discoloration. His medical history included chronic kidney disease, chronic hepatitis C infection, cirrhosis, ischemic cardiomyopathy with an implantable cardioverter-defibrillator (ICD), and atrial fibrillation with prophylactic apixaban. He had recurrent staphylococcus bacteremia due to infection of an ICD lead and had been treated for the past six months with minocycline, 100 mg twice daily. What would you do next?
