Overview
Lipoma may be classified into 12 subtypes: adenolipomas, angiolipoleiomyomas, angiolipoma, cerebellar pontine angle and internal auditory canal lipomas, chondroid lipomas, corpus callosum, hibernomas, intradermal spindle cell lipomas, neural fibrolipomas, pleomorphic lipomas, spindle-cell lipomas, and superficial subcutaneous lipomas.
Classification
Lipomas can be classified according to their anatomical locations into:[1]
- Dermal
- Subcutaneous
- Subfascial
Another suggested classification is according to the related structure:
- Muscles-related lipoma
- Nerve-related lipoma
- Bone-related lipoma
- Synovium-related lipoma
World health organization (WHO) classification system classified lipomatous tumors into the following subtypes:[2]
- Lipoma
- Lipomatosis
- Lipomatosis of nerve
- Lipoblastoma/lipoblastomatosis
- Angiolipoma
- Myolipoma of soft tissue
- Chondroid lipoma
- Spindle-cell lipoma/pleomorphic lipoma
- Hibernoma
Weiss and Goldblum classified Lipomatous tumors into the following subtypes. This classification system has shown more clinical utility.[3]
- Lipoma which may be classified as superficial or deep, single or multiple
- Variants of lipoma including:
- Angiolipoma
- Myolipoma
- Chondroid lipoma
- Lipoblastoma
- Lpindle-cell/pleomorphic lipoma
- Lipomatous tumors including:
- Intramuscular lipoma
- Intermuscular lipoma
- Lipomatosis of nerve
- Lipoma of the tendon sheath and joint
- Infiltrating lipomas including
- Diffuse lipomatosis
- Symmetric lipomatosis
- Adiposis dolorosa
- Hibernoma
