“…Neurofibromas can be classified regarding to their location, morphology, and growth pattern as either solitary (also known as localized, sporadic, or nodular form), diffuse cutaneous (more common at the head and neck), plexiform (multinodular tumors associated with deep nerves or plexus), or massive soft-tissue form (often a diffuse infiltration of a distal extremity). 2 , 3 , 4 , 6 , 7 The solitary NF is the most commonly found subtype (approximately 90%), and usually emerges from superficial cutaneous nerves as extraneural and pediculated in relation to the nerve. More rarely, a solitary NF may originate from deep-located nerves, and will typically result in fusiform expansion of the nerve trunk (intraneural subtype).…”
