Final answer:
An indurated erythematous lesion with scale is typically seen on the legs or face. It is a characteristic feature of erythema nodosum, a condition that causes inflammation in the subcutaneous fat cells of the hypodermis. It should be considered as erythema nodosum until proven otherwise.
Step-by-step explanation:
An indurated erythematous lesion with scale is typically seen on the legs or face. This type of lesion is a characteristic feature of a condition called erythema nodosum, which causes inflammation in the subcutaneous fat cells of the hypodermis, resulting in red nodules. Erythema refers to redness at the site of inflammation, usually due to dilation of blood vessels in the area to help bring in white blood cells. The presence of scale indicates that the lesion has a scaly appearance, which can be seen in various skin conditions. Therefore, an indurated erythematous lesion with scale should be considered as erythema nodosum until proven otherwise.
