case_images: T1 T2 hypo-intense lesion in the inferior aspect of right supraclavicular region with focal areas of calcification. The lesion was diffusely infiltrating the adjacent soft tissue [Figure 1].
case_images: Cytology smears showing fibromatosis; (a) Bland spindle cells embedded in hypocellular dense stromal fragment (H and E, x200); (b) Spindle cells seen within stromal fragments (H and E, x200); (c) Oval to spindle cells embedded in metachromatically staining matrix material (MGG, x400); (d) Oval to spindle cells with bland nuclear chromatin and inconspicuous nucleoli (H and E, x400)

case_images: FNAC from the mass was performed which revealed moderately cellular smears and showed scattered spindle to fusiform cell clusters, stromal fragments [Figure 2a] and collagen matrix material. These spindle cells were embedded in or were in proximity to the densely eosinophilic collagen matrix material [Figure 2b and 2c]. The cells were oval to spindle shaped with tapering ends, bipolar nuclei, bland nuclear chromatin and inconspicuous nucleoli [Figure 2d].
