| Histologically, all demonstrated a densely cellular storiform or vaguely fascicular pattern, broadly extending into the subcutaneous fat. |
| The histological diagnosis relies on identification of two separate components, fascicular myofibroblastic at the periphery and hemangiopericytome in the centre. |
| Most of the cortex was composed of fascicular cells which had nonvacuolated, nonhoneycombed eosinophilic cytoplasm. |
| The cut surface of the lesion was tan-white and had a faint fascicular pattern. |
| Nerve biopsy revealed copious light chain deposition which subverted the normal architecture of the endoneurium and epineurium resulting in massive fascicular hyalinosis and epineural arteries disruption, respectively. |
| Some tumors may display a fascicular or spindled appearance. |
