Question 1

During the dermatological physical examination of a patient with a generalized eruption, the examiner observes the formation of an epidermal detachment upon applying lateral tangential shearing pressure to normal-appearing perilesional skin. Which clinical sign and associated pathophysiological mechanism are demonstrated?

Nikolsky sign (sinal de Nikolsky), indicating loss of keratinocyte-keratinocyte cell adhesion (acantholysis) or complete basal-suprabasal junctional failure. Asboe-Hansen sign, indicating lateral accumulation of edema within the subcorneal space under mechanical occlusion. Darier sign, indicating sudden degranulation of dermal mastocytes with histamine release upon mechanical stroking. Auspitz sign, indicating exposure of dilated and tortuous dermal papillary capillaries following mechanical removal of adherent parakeratotic scales.

Correct Answer:

Nikolsky sign (sinal de Nikolsky), indicating loss of keratinocyte-keratinocyte cell adhesion (acantholysis) or complete basal-suprabasal junctional failure.

Question 2

A 32-year-old male presents with reddish-brown macules and papules on the trunk. Stroking one of the lesions with a blunt wooden spatula produces rapid local swelling, erythema, and an urticarial wheal confined to the stroked lesion within 5 minutes. What is this diagnostic phenomenon, and which condition does it confirm?

Auspitz sign, pathognomonic of guttate psoriasis. Darier sign (sinal de Darier), pathognomonic of cutaneous mastocytosis (urticaria pigmentosa). Koebner isomorphic phenomenon, indicative of lichen planus. Hutchinson sign, indicative of subungual melanoma progression.

Correct Answer:

Darier sign (sinal de Darier), pathognomonic of cutaneous mastocytosis (urticaria pigmentosa).

Question 3

Which of the following describes the Koebner isomorphic phenomenon (fenômeno isomórfico de Koebner) and correctly lists dermatological diseases where it is classically observed?

Immediate wheal and erythema appearing within seconds of scratching normal skin, typical of symptomatic dermographism and acute cholinergic urticaria. Spontaneous peripheral enlargement of flaccid bullae upon vertical digital pressure, seen in bullous pemphigoid and porphyria cutanea tarda. Appearance of typical disease-specific isomorphic lesions at previously unaffected sites following non-specific mechanical, physical, or chemical trauma, characteristically seen in Psoriasis, Lichen Planus, and Vitiligo. Development of pinpoint capillary hemorrhage beneath silver-white scales during curettage, typical of pityriasis rubra pilaris.

Correct Answer:

Appearance of typical disease-specific isomorphic lesions at previously unaffected sites following non-specific mechanical, physical, or chemical trauma, characteristically seen in Psoriasis, Lichen Planus, and Vitiligo.

Question 4

A 45-year-old female presents with multiple yellowish-brown translucent papules and plaques on the midface. Diascopy (vitropressão) is performed by pressing a transparent glass slide firmly against the active infiltrated border of a lesion. The examiner notes the persistence of discrete 'apple-jelly' (geléia de maçã) yellowish-brown translucent nodules. This semiological sign strongly suggests which histopathological finding?

Accumulation of lipid-laden histiocytes in the upper reticular dermis (Touton giant cells). Dense subepidermal band-like infiltrate of CD8+ T lymphocytes with colloid Civatte bodies. Subcorneal collections of neutrophils with complete epidermal acantholysis. Dermal epithelioid non-caseating or caseating granulomas with clearance of background erythema and telangiectasia.

Correct Answer:

Dermal epithelioid non-caseating or caseating granulomas with clearance of background erythema and telangiectasia.

Question 5

In dermoscopy of non-melanocytic cutaneous lesions, which set of dermoscopic structures is most specific and characteristic for a pigmented Seborrheic Keratosis (ceratose seborreica)?

Comedo-like openings (crypts), milia-like cysts, hairpin vessels with white halos, and brain-like / gyri-and-sulci pattern. Arborizing telangiectasias, blue-gray ovoid nests, and ulceration. Atypical pigment network with thick lines, irregular dots/globules at the periphery, and blue-white veil. Crown vessels surrounding a central yellowish-white umbilicated keratinaceous core.

Correct Answer:

Comedo-like openings (crypts), milia-like cysts, hairpin vessels with white halos, and brain-like / gyri-and-sulci pattern.
