In brief: Differences
A pilonidal cyst generally occurs in hairy areas and occurs due to ingrowth of the hairs.
A sebaceous cyst occurs when a sebaceous gland becomes blocked and sebaceous material secreted builds up under the skin. Both conditions generally require surgical excision.

In brief: Big difference
A sebaceous cyst may occur anywhere sebaceous glands (skin oil glands) are located.
These cysts have a lining that sheds cells into the central cavity producing a cheese like appearing white material. A pilonidal cyst occurs in a specific location (near your tailbone) and may be filled with a variety of structures that derive from outer layer of the skin (ectoderm): hair, sebaceous, teeth, etc.
