What is Lipedematous scalp?
Lipedematous scalp is a rare disorder characterized by thickening of the adipose subcutaneous layer (fat tissue under the scalp). When associated with lack of hair, it is known as lipedematous alopecia. The scalp is soft, spongy or thick in the forehead area (apex) and in the back (occiput) of the head.
What counts as the scalp?

Which is the innermost layer of the skull?
It is a dense and irregular connective tissue that adheres to the calvarial bone of the skull. It has a vascular supply that supports the underlying calvarium. It has two layers; the fibrous layer (outermost) and the cambium layer, which is the innermost layer.
What are the layers of skin that make up the scalp?
Your scalp is formed by layers of skin and subcutaneous tissue that covers the bones of the cranial vault. The scalp is soft tissue and acts as a barrier to protect the cranial vault from physical trauma or infectious agents.
Where does the greater occipital nerve supply the scalp?
Lesser occipital nerve – A branch of the cervical plexus (C2); it supplies the scalp over the lateral occipital region. Greater occipital nerve – A branch of the posterior ramus of the second cervical nerve; it supplies the scalp in the median plane at the occipital region, up to the vertex.
Where does the innervation of the scalp come from?
The scalp receives cutaneous innervation from six main nerves, which arise from the trigeminal nerve or the cervical nerves. Supratrochlear nerve – branch of the ophthalmic nerve which supplies the anteromedial forehead.
