CD68-Positive Cells in Hepatic Angiomyolipoma.
نویسندگان
چکیده
Four resected specimens of hepatic angiomyolipoma in which uptake of Sonazoid was observed in the postvascular phase of Sonazoid-enhanced ultrasonography were analyzed. Macrophage localization in the tumor was revealed pathologically by immunohistochemical staining for CD68. CD68-positive cells were observed in the tumor in all cases. The density of CD68-positive cells was 100/mm2, and the ratio of CD68-positive cell density in the tumor to that in the surrounding parenchyma was 32-171%. These results suggested that the uptake of the contrast agent Sonazoid was related to the density of CD68-positive cells.

INTRODUCTION A hepatic angiomyolipoma is a rare benign tumor of the liver composed of a mixture of smooth muscle cells, blood vessels and a variable amount of adipose tissue. Differentiating them from malignant liver tumors can often be very difficult. CASE PRESENTATION We report the case of a 43-year-old Caucasian man presenting with a large liver mass in the right lobe. The results of magne...

PEComas are an uncommon group of mesenchymal neoplasms that exhibit perivascular epithelioid cell differentiation. The term PEComa includes a collection of different subcategories, such as lymphangioleimyomatosis, clear cell tumor of the lung, and angiomyolipoma (AML) which is the topic of discussion in this article. The main problem concerning the diagnosis of hepatic AML is the wide non-speci...

Hepatic epithelioid angiomyolipoma (AML) is a rare, benign, mesenchymal neoplasm found in both males and females, and most commonly encountered in adult females. These lesions are difficult to diagnose by imaging, especially when fatty component is scant or absent. Histomorphologically, they resemble hepatocellular carcinoma. The tumor cells are strongly positive for homatropine methylbromide-4...

Hepatic angiomyolipoma (AML) is notoriously difficult to diagnose without an invasive surgery even with the recent development of the various imaging modalities. Additionally, recent reports showed its malignant behavior after the surgery; it is important to diagnose the character of each tumor including the possible malignant potential and determine the postoperative management for each case. ...
