The neoplasm was composed of sheet-like and glandular neoplastic cells embedded in abundant loose fibrovascular stroma.
The tumor is composed of a complex, arborizing, and interwoven papillary architecture, usually showing hyalinized fibrovascular cores (figure 1).
1) The tumor cells can be spindled, plasmacytoid, or polygonal and are separated by thin fibrovascular septae (Figure 1, C and D).
The papillae show hyalinized fibrovascular cores and lined by round to polygonal cells with clear to eosinophilic cytoplasm, monomorphic nuclei and eosinophilic nucleoli.
5) Because there were no drusen or fibrovascular tissue in either eye and the findings were symmetrical, this diagnosis was excluded.
Histopathology revealed an unencapsulated, poorly demarcated, highly cellular neoplasm composed of islands and trabeculae of neoplastic cells embedded in abundant loose fibrovascular stroma which completely obliterated the cortical bone and sinuses of the rostral skull and infiltrated the surrounding muscle and soft tissue.
In addition to the other subtypes of lymphangiomatous polyps, differential diagnosis of such a lesion of the tonsil includes other benign tonsillar lesions like fibroma, fibroepithelial polyp, hairy polyp, hemangiomatous hamartoma, fibrovascular polyp, lipoma, neurofibroma, schwannoma, and plasma cell granuloma (2, 10).
Caption: Figure 3: Inverted papilloma: Circumscribed margins of lesion show thickened epithelial covering of squamous type, underneath it are multiple irregular papillary folds with fibrovascular cores infiltrating into deeper connective tissue stroma which is fibromyxoid in nature.
36) In the final stage of PSR, persistent haemorrhages and mechanical traction created by fibrovascular retinal membranes can lead to full-thickness retinal breaks and rhegmatogenous retinal detachments.
The mass was composed of cuboidal and polygonal cells arranged in elongated tubular structures with multifocal papillary projections into the lumen supported by a fine fibrovascular stroma (Figure 1C-D).
Enhancement of the fibrovascular stroma of the tumor results in the characteristic layered pattern or swirled appearance.
This effect is thought to be a result of reduction of leakage from the foci of neovascularization, as evident on fluorescein angiography, and regression of the neovascular component of fibrovascular tissue.
