| Note the superficial scale and tendency for the individual lesions to merge into a retiform pattern. |
| Although they can occur in young patients, a retiform pattern has never been described in granulosa cell tumors. |
| To our knowledge, retiform and papillary features have never been reported in a solitary fibrous tumor. |
| On the smaller islands, the quartz-rock is intersected by retiform veins of iron ore. |
| The retiform pattern consists of elongated, slitlike branching tubules containing intraluminal papillae lined by flattened to cuboidal cells. |
| We report a 66-year-old man with a spinal, extradural solitary fibrous tumor showing unique retiform and papillary architecture. |
