Cutaneous ultrasound of the nuchal-type fibroma: diagnostic clues and surgery planning.

Abstract

Nuchal-type fibroma is a rare, benign tumour, arising from the connective tissue and characterized by their usual location in the posterior neck, although extra-nuchal locations may also occur. The excision of nuchal-type fibroma is curative, although it presents as a large poorly circumscribed lesion in the dermal and subcutaneous fat layer, with adipose tissue and muscle fascicles entrapment, what can lead to partial excisions and relapses. Due to its rarity, little is known about the sonographic appearances of nuchal-type fibroma. An early identification and correct extension evaluation is essential to facilitate adequate treatment. Through two clinical cases, we illustrate in this article the utility of cutaneous ultrasound in the early diagnosis of these tumours, highlighting its role in the diagnosis but also in the pre-surgical evaluation improving margins assessment and delimitation.
