Histological examination showed mature adipocytes, diffusely infiltrating striated muscle fibres, [Figure 1] and abundant mucoid stroma [Figure 2].
Mature adipose tissue was admixed with abundant mucoid stroma (H and E, x 20)

Histological examination showed mature adipocytes, diffusely infiltrating striated muscle fibres, [Figure 1] and abundant mucoid stroma [Figure 2].
Mucoid areas showed bland-appearing spindle cells and multinucleated giant cells with radially arranged nuclei in a "floret-like" pattern (H and E, x 20)

In this myxoid background were present bland-appearing spindle cells and multinucleated giant cells with radially arranged nuclei in a "floret-like" pattern [Figure 3].
The spindle and giant cells were strongly positive for CD34 (immunoperoxydase, x 40)
