Morphology
The term is compositionally descriptive: 'angioma' is a blood-vessel tumor and 'spider' describes the radial, spider‑like appearance, so the overall meaning (a vascular lesion with a central spot and radiating capillaries) is directly inferable from the constituents. This type of noun‑noun descriptive formation is transparent and cross‑linguistically common, so a B1 learner who knows both words would likely understand the MWE.
Etymology
The noun spider angioma comes from how the skin mark looks: a small red center with thin blood lines spreading out like a spider's legs, and angioma is a medical word for a small blood-vessel spot. So the name means 'a small blood vessel on the skin that looks like a spider', which helps doctors describe this mark.
