Final answer:
The 'comedo' is technically known as a blackhead, which is a type of acne lesion that occurs when a hair follicle is clogged with sebum and skin cells, resulting in black or white-topped bumps on the skin.
Step-by-step explanation:
The technical name for a 'comedo' or 'comedone' is C. Blackhead. The term refers to a non-inflammatory lesion resulting from hair follicles clogged by shed skin cells and sebum, which is an issue typically associated with acne. When the sebum is exposed to air, it can oxidize and appear blackish, which is characteristic of blackheads. On the other hand, whiteheads are comedones that are covered by skin and do not get oxidized, retaining their whitish color.
It's important to note that other options such as 'nevus' refer to moles or 'macule' to flat skin lesions, which are not the same as comedones. The correct choice being discussed here is a blackhead, which is one of the two main types of acne lesions, the other being a whitehead. Understanding these concepts can help in the identification and treatment of acne and its related skin disturbances.
