Question:
A reddish blue, irregularly shaped, solid and spongy mass of blood vessels that may be present at
birth and enlarge during the first 10 to 15 months is characteristic of a:
cavernous hemangioma. Correct
strawberry mark.
telangiectasia.
port-wine stain.
Explanation:
A cavernous hemangioma appears as a reddish blue, irregularly shaped, solid and spongy mass
of blood vessels. It may be present at birth, may enlarge during the first 10 to 15 months, and
will not involute spontaneously. A port-wine stain is a large, flat, macular dark red or purplish
patch covering the scalp or face, frequently along the distribution of cranial nerve V and
intensifies with crying, exertion, or exposure to heat or cold. A strawberry mark is a type of
hemangioma that has a raised bright red area with well-defined borders about 2 to 3 cm in
diameter. It does not blanch with pressure. Telangiectasia are caused by vascular dilation and are
permanently dilated blood vessels that are visible on the skin surface.
Question:
A chancre is defined as a:
group of small scattered vesicles.
painless ulceration. Correct
papule of many shapes.
non-tender penile indurated nodule.
Explanation:
A chancre is defined as a painless ulceration formed during the primary stages of syphilis. A
group of scattered small vesicles is associated with genital herpes. Papules appearing in many
shapes that can be raised, flat, or cauliflower-like are characteristic of genital warts (condylomata
acuminata). Non-tender indurated nodules are associated with carcinoma of the penis.
Question:
, Transverse depressions of the nail plates, usually bilateral, resulting from temporary disruption
of proximal nail growth from systemic illness is termed:
Terry's nails.
Beau's lines. Correct
Mees' lines.
pitting nails.
Explanation:
Beau's lines are deep grooved lines that run from side to side on the fingernail. They appear as
transverse depressions of the nail plates, usually bilateral, resulting from temporary disruption of
proximal nail growth from systemic illness, such as severe illness, cold stress in the presence of
Reynaud's disease, and trauma. With Terry's nails, the nail plate turns white with a ground-glass
appearance, a distal band of reddish brown, and obliteration of the lunula. Mees' lines present as
curving transverse white bands that cross the nail parallel to the lunula. They arise from the
disrupted matrix of the proximal nail, vary in width, and move distally as the nail grows out.
These lines are seen in arsenic poisoning, heart failure, Hodgkin’s disease, chemotherapy, carbon
monoxide poisoning, and leprosy. Pitting nails present as punctate depressions of the nail plate
caused by defective layering of the superficial nail plate by the proximal nail matrix. They may
be associated with psoriasis, but also seen in Reiter’s syndrome, sarcoidosis, alopecia areata, and
localized atopic or chemical dermatitis.
Question:
A child has a maculopapular, blotchy rash and on examination of his mouth, red eruptions with
white centers on the buccal mucosa are visualized. These eruptions are called:
rubella spots.
aphthous ulcers.
Pastia's spots.
Koplik spots. Correct
Explanation:
Koplik spots are seen with measles. They are small, white spots (often on a reddened
background) that occur on the inside of the cheeks early in the course of red measles, rubeola.
Pastia's spots are pink or red lines that are formed of confluent petechiae found in skin creases
