Sample CMD Dermatología Practice Questions
Try these sample questions to review concepts for the CMD Dermatología exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 104+ question experience with AI tutoring.
1A 38-year-old man presents with well-demarcated erythematous plaques covered by thick, silvery-white micaceous scales on the extensor surfaces of his elbows, knees, and lumbosacral region. Auspitz sign is positive upon gentle scraping of the scales. Histopathologic examination demonstrates hyperkeratosis, confluent parakeratosis, regular elongation of rete ridges, and intracorneal collections of neutrophils. What is the pathognomonic histopathologic finding represented by these intracorneal neutrophil aggregates?
2A 45-year-old woman with a history of chronic plaque psoriasis presents to the emergency department with high-grade fever, chills, severe generalized skin pain, and leukocytosis (24,000/µL). Physical examination reveals widespread fiery erythroderma studded with hundreds of non-follicular, sterile, pinpoint pustules coalescing into 'lakes of pus' across her trunk and extremities. A review of her medications indicates she abruptly discontinued oral prednisone prescribed by an external clinic two days ago. Genetic analysis in generalized pustular psoriasis of this type frequently reveals a loss-of-function mutation in which gene?
3A 14-year-old boy presents with the sudden eruption of multiple small, 2 to 6 mm, teardrop-shaped erythematous scaly papules distributed symmetrically across his trunk and proximal extremities. His parents report that he had a severe sore throat accompanied by fever 2 weeks prior. He has never had skin lesions previously. Which human leukocyte antigen (HLA) allele and laboratory test are most strongly associated with this clinical variant of psoriasis?
4A 42-year-old man with severe chronic plaque psoriasis involving 18% of his body surface area (BSA) and a PASI score of 22 has failed topical therapy, phototherapy, and oral methotrexate due to persistent hepatotoxicity. His dermatologist decides to initiate biologic therapy targeting specifically the p19 subunit of interleukin-23. Which of the following therapeutic agents corresponds to this specific mechanism of action?
5A 50-year-old woman with psoriatic arthritis complains of fingernail abnormalities. On examination, several fingernails exhibit localized areas of yellowish-brown discoloration resembling drops of oil under the nail plate ('oil drop' or 'salmon patch' sign), along with prominent subungual hyperkeratosis. In the functional anatomy of the nail unit, which anatomical structure is responsible for producing these specific clinical signs?
6A 34-year-old woman receiving adalimumab for Crohn disease presents 6 months after starting therapy with newly developed, painful, hyperkeratotic pustular plaques over her palms and soles, accompanied by scaly scalp plaques. Skin biopsy confirms psoriasiform epidermal hyperplasia with subcorneal pustules. She has no prior personal or family history of psoriasis. What is the most appropriate pathophysiologic explanation for this phenomenon?
7A 5-year-old boy is brought for evaluation of intensely itchy, dry skin that worsens at night. Physical examination reveals excoriated, lichenified erythematous plaques localized predominantly to the antecubital and popliteal fossae, wrists, and periorbital area. According to the Hanifin and Rajka diagnostic criteria for atopic dermatitis, which of the following is a major criterion rather than a minor one?
8A 22-year-old man with lifelong severe atopic dermatitis and ichthyosis vulgaris undergoes genetic testing. He is found to harbor heterozygous null mutations in the FLG gene. What primary physiological abnormality directly results from this filaggrin deficiency in the epidermis?
9A 28-year-old patient with moderate-to-severe atopic dermatitis refractory to high-potency topical corticosteroids and topical calcineurin inhibitors is initiated on dupilumab subcutaneously. What is the molecular target of dupilumab?
10A 3-year-old girl with active flexural atopic dermatitis presents with sudden acute deterioration. Over 48 hours, she developed fever (39°C), irritability, and clusters of monomorphic, dome-shaped, umbilicated vesicles on an erythematous base overlying her cheeks and neck, which rapidly progress to punched-out circular erosions with hemorrhagic crusts. What is the immediate treatment of choice for this condition?
