Hyporeflective ovoid structures associated with the hair matrix
Possess a “hazy” granular texture due to cell aggregations and secretary lumen spaces within the gland tissue
Located within the reticular dermis, full gland not usually seen
Typically only the upper facing of the gland is seen
The “hazy” granular texture of the gland’s cells is often surrounded by a darker hyporeflective border to the surrounding dermal collagen, which also isolates individual lobules of the gland
Even if a descending hair cannot be seen, sebaceous glands are identifiable in the dermis by appearing more hyporeflective than their collagenous surroundings and the distinct change in texture
In areas such as the cheek and forehead the frequency of sebaceous glands increases leading to the appearance of multiple gland aggregations throughout the scan area
In areas where there is a larger tissue fluid content sebaceous glands appear as more hyperreflective structures relative to their surroundings still identifiable by their unique texture
