Answer to the Question

Sebaceous glands are specialized glands that secrete sebum, an oily substance that lubricates the skin and helps protect it from environmental damage. While these glands are distributed across various parts of the body, there are certain areas where they are absent.

Detailed Analysis

1. External Genitalia: The external genitalia do have sebaceous glands, though their distribution can vary.
2. Face: The face generally has a high concentration of sebaceous glands, particularly in areas like the forehead and nose.
3. Palms and Soles: The palms of the hands and the soles of the feet are unique in that they lack hair follicles and, consequently, sebaceous glands. This is a significant trait of these areas, as they are designed for grip and protection without the need for the oily secretion from sebaceous glands.
4. Trunk: The trunk of the body, including the chest and abdomen, has numerous sebaceous glands.

Final Answer

The area(s) of the body that lack sebaceous glands is palms and soles.
