The endothelial cells are enlarged and appear epithelioid
or histiocytic (figure 2).
Triphasic and epithelioid
minimal fat renal angiomyolipoma and clear cell renal cell carcinoma: Qualitative and quantitative CEUS characteristics and distinguishing features.
Spindle cell melanoma: a comparison of the cytomorphological features with the epithelioid
Histologic examination showed a neoplasm composed of sheets, nests, and fascicles of epithelioid
and spindle cells in a fibrocollagenous stroma, which in some areas were arranged in a pseudoalveolar pattern (Figure 1, A).
Renal angiomyolipoma with epithelioid
sarcomatous transformation and metastases: demonstration of the same genetic defects in the primary and metastatic lesions.
Angiomyolipoma (AML) are benign tumours composed of varying amounts of thick-walled dysplastic blood vessels, smooth muscle and mature adipose tissue derived from epithelioid
The histological study showed chronic granulomatous non-necrotizing lymphadenitis with epithelioid
and giant cells.
Presence of macrophages, epithelioid
cells and langhans type of giant cells were predominantly found.
Objective: An important difficulty pathologists confront concerning thoracic pathology is the differentiation of pleural epithelioid
malignant mesothelioma from pulmonary adenocarcinoma infiltrating into the pleura or metastatic adenocarcinoma.
Some areas covered include acquired melanocytic nevi, congenital nevi and tumefactions, blue nevi and variants, combined nevi, pigmented epithelioid
melanocytoma, tumorigenic melanomas of WHO classification categories, neutrotropic melanoma, metastastic melanoma, and nonmelanocytic melanoma simulants.
She was diagnosed with epithelioid
haemangio-endothelioma when she was just 12 and despite knowing that it would eventually kill her, family say that she never let it get her down.
Histopathology of bioptic samples revealed epithelioid
neoplastic proliferation with a tubulopapillary pattern, falsely suggesting metastatic adenocarcinomatosis.
