Nuchal Fibroma Presenting as a Lateral Neck Mass / 대한이비인후과학회지

ABSTRACT

Nuchal fibroma (NF) is a rare, benign soft tissue tumor of the posterior neck, but can also occur extranuchally. Usually, it is a slow-growing, asymptomatic solitary mass that occurs more frequently in middle-aged males. Histologically, hypocellular dense collagens in the dermis and subcutaneous layer are characteristic. Careful total excision is necessary for the treatment and accurate diagnosis. We report an unusual case of a NF occurring at the lateral neck deeply under platysma muscle. This lesion should be included in the differential diagnosis of soft tissue masses arising in the posterior neck or rarely in the lateral neck as in our case, especially when the diagnosis is not definite.
