Nuchal-type fibroma (NTF) is a benign fibrous tumour that commonly occurs in the nuchal region such as the posterior neck. It is associated with Gardner syndrome (familial adenomatous polyposis), diabetes mellitus and repetitive blunt trauma [1]. Nuchal-type fibromas can occur in the extra-nuchal sites including the shoulders, face, and buttocks, but has never been reported in the hands. On ultrasound, NTFs can appear as hypoechoic masses, while MRI typically shows low signal intensity on T1-weighted imaging. Histologically, they are strongly CD34-positive and negative for SMA and beta-catenin. In some cases, NTFs contain localised nerve proliferation, similar to post-traumatic neuromas.
We present a first ever case of NTF in a hand in a 32 year-old builder. Nuchal-type fibroma should be considered as a differential diagnosis of hand masses.
