AND RATIONALES A+ GRADED.
What type of skin cancer most commonly presents as a scaly red patch,
open sores, elevated growths with a central depression or warts on the skin
and is the most common skin malignancy among Blacks and Asian Indians.?
a. Squamous cell carcinoma
b. Basal cell carcinoma
c. Melanoma
Correct Answer -a. Squamous cell carcinoma
Rationale: Risk factors for squamous cell carcinoma include: chronic
scarring and areas
of chronic inflammation. Squamous cell carcinoma rapidly grows but is
confined to a
primary area and is seen in non sun-exposed lower body parts like hips, legs,
and feet in
POC. Basal cell carcinoma is characterized by a pearly translucent or
"shiny" and small reddish fleshy patch with tiny blood vessels on the
surface and sometimes ulceration of the tumor. Its characteristic features
(more likely to have pearly translucent WITH pigmentation appearance in
POC) are not clinically very apparent in dark skin types leading to difficulty
in diagnosing. It rarely metastasizes and rarely causes death. Basal cell
carcinoma is most commonly found on the face, head, or neck/high areas of
sun exposure in all people and is the most common cutaneous malignancy
in Caucasians, Latinos, Chinese and Japanese Asians. It has a higher
,incidence among darker-skinned populations living in sunnier climates.
Melanoma is usually characterized by a brown or black mark. It can present
as a red or white mark on POC. Melanoma can metastasize
quickly and spread to other body parts. It requires surgical removal of large
areas due to
its deep rooting into the skin.
True or False: POC are more likely to die from skin cancer.
Correct Answer -True
Rationale: Due to a delay in detection or presentation resulting in a late
stage diagnosis.
This delay can be attributed to many things: lack of access to services due to
socioeconomic barriers such as red lining and the limited amount of
research that has been conducted on skin cancer presentation on POC.
Melanomas are more likely to develop in what areas on POC
a. Face and neck
b. Forearms and back
c. Chest and legs
d. Palms of the hands and soles of the feet
Correct Answer -d. Palms of the hands and soles of the feet
Rationale: Melanomas are more likely to develop in areas of less pigmented
skin that are not usually exposed to sun.
, True or False: Transmission of shingles occurs from direct contact with the
lesions and produces shingles on the newly infected individual.
Correct Answer -False
Rationale: Shingles, or herpes zoster, is a reactivation of the varicella virus
as immunity
to the virus wanes. Transmission of shingles occurs from direct contact with
the lesions
but contact will produce chickenpox not shingles. Because of this, shingles
can only be
produced systemically, not by contraction from an infected individual. And if
an individual
comes into contact with lesions, only those individuals who have not been
vaccinated or
who have not experienced prior varicella infection are at risk for contracting
chickenpox
via contact with these lesions.
Anaphylactic urticaria results from an IgE mediated breakdown of which
type of cells?
a. Eosinophils
b. Monocytes
c. Mast cells
d. Basophils
Correct Answer -c. Mast cells
