Differential diagnosis	Features
Angiomyolipoma	Collection of fat cells with muscular arteriole
Angiomyofibroblastoma	Loose, myxoid, and fibroblastic element
Juvenile nasopharyngeal angiofibroma	Cornified to the nasopharynx and histopathologically shows homogenous fibroplasias with immature collagen, and sinus-like vascular channels
Solitary fibrous tumors	Do not exhibit prominent vascular elements
Spindle cell lipoma	Adipocytes intimately interspersed with spindle cells
Pyogenic granuloma	Large thin-walled vessels in a loose connective tissue stroma infiltrated throughout by leukocytes
