Morphology

sebaceous + cyst

The meaning is directly compositional: 'sebaceous' (related to oily/greasy substances) modifies 'cyst' (an abnormal, often fluid-filled structure), so a learner who knows both words can infer a cyst containing oily/greasy material under the skin. The same lexical logic exists in many languages (e.g., Spanish 'quiste sebáceo'), so the relation is predictable rather than idiomatic.

Etymology

Sebaceous cyst is named for what it is: sebaceous refers to 'sebum', the oily stuff the skin makes, and cyst means a small 'sac' or 'lump'. So the term describes a usually harmless 'lump' under the skin.
