CCRN
histopathology indicates the presence of
elastic cartilage enclosed by various skin structures such as
eccrine glands,
adipose tissue, and
pilosebaceous units. To assess the extent of the lesion as well as look for any underlying
sinus tracts,
ultrasonography alongside
computed tomography (CT) scans can be used. Alternative diagnoses for CCRN consist of
thyroglossal duct cyst,
hair follicle naevus,
fibroepithelial polyp, and
branchial cleft cyst. Thyroglossal duct cysts are typically found in the midline of the neck, near the
hyoid bone, and move with tongue protrusion or swallowing. Hair follicle naevus appears as a single, skin-colored
papule and can be associated with
hypertrichosis. Fibroepithelial polyps are soft, fleshy growths of
collagen fibers and
blood vessels that hang off the skin. Branchial cleft cysts can manifest as
cysts,
fistulas, sinus tracts, or cartilaginous remnants on the front of the neck and upper chest. == See also ==
