Histological examination of the tumor revealed the following different architectural patterns: pseudopapillary and angiomatous
areas [Figure 1]c and [Figure 1]d.
This type of nAMD is referred to as a retinal angiomatous
proliferation (RAP) lesion, (5) and is commonly associated with exudates, intraretinal and subretinal haemorrhage, and serous detachments of the RPE.
5), there may be five alternatives: teratoid origin coupled with significant overgrowth of the myomatous elements, smooth muscle cells that migrate from the nipple during embryological life, a multipotent mesenchymal cell, angiomatous
smooth muscle and myoepithelial cells.
Angiolipoma can be classified by the ratio of adipose and vascular tissue components as predominantly lipomatous or angiomatous
The term "pseudoangiomatous" describes the histological pattern which resembles an angiomatous
These included angiomatous
meningioma, Non-Hodgkins lymphoma, metastatic renal cell carcinoma, cerebellopontine angle fibrous meningioma, and craniopharyngioma.
Total 50 cases of meningiomas were studied histologically, among them the most common variant is meningothelial meningioma, 32 cases (64%), followed by psammomatous consisting of 5 cases (10%), followed by angiomatous
consisting of 4 cases (8%), followed by fibroblastic and atypical, each variant consisting of 3 cases (6%), followed by microcystic, clear cell, and papillary variant each consisting of 1 case (2%).
The tumor may contain high-, iso-, and low-attenuating areas, reflecting the angiomatous
, sclerosing, and cystic components, respectively.

Angiolymphoid hyperplasia with eosinophilia (AHE) has been known by a variety of different names, such as epithelioid hemangioma, pseudopyogenic granuloma, inflammatory angiomatous
nodule, papular angioplasia, subcutaneous angioblastic lymphoid hyperplasia with eosinophilia and lymphofolliculosis, intravenous atypical vascular proliferation and histiocytoid hemangioma.
9) observed greater advantages of laser over the cold instruments considering micro-precision and capacity of photo-coagulating small vessels on the mucous surface of angiomatous
polyps, laser is indicated to treat vascular polyps and granulomas.
