ANGIOSARCOMA Figure 1-123 ANGIOSARCOMA A: Pleomorphic epithelioid cells form blood-filled vascular spaces. B: Endothelial markers like CD31 (pictured here), CD34, and ERG are confirmatory. More about this image found in ANGIOSARCOMA A: Pleomorphic epithelioid cells form blood-filled vascular s...

PRIMARY ADRENAL ANGIOSARCOMA Figure 12-10 PRIMARY ADRENAL ANGIOSARCOMA A: There is well-developed vasoformative architecture with sinusoidal growth between cords of vacuolated cortical cells. Acute inflammatory cells and eosinophils are also present. B: Primary adrenal angiosarcoma (same case More about this image found in PRIMARY ADRENAL ANGIOSARCOMA A: There is well-developed vasoformative arch...

ANGIOSARCOMA Figure 11-25 ANGIOSARCOMA A: Low-power image of an angiosarcoma in which vascular channels are seen infiltrating through the dermis. B: At intermediate power, the interanastomosing channels as well as the cytologic atypia of the endothelial cells are appreciated. C: At high power More about this image found in ANGIOSARCOMA A: Low-power image of an angiosarcoma in which vascular chann...

ANGIOSARCOMA Figure 11-27 ANGIOSARCOMA A: Low-power view of another angiosarcoma with spindle cell morphology. B,C: Intermediate- (B) and high-power (C) views show the nuclear atypia of the spindle cells, mitotic figures, and some red blood cells. CD31 and ERG were positive in the spindle cells.

ANGIOSARCOMA Figure 11-29 ANGIOSARCOMA A: Low-power image of a subtle variant of angiosarcoma mimicking radiation dermatitis. The cells of concern are seen at the left hand side of the field. B: High-power view shows the scattered highly atypical endothelial cells of angiosarcoma. C: Another More about this image found in ANGIOSARCOMA A: Low-power image of a subtle variant of angiosarcoma mimick...

EPITHELIOID ANGIOSARCOMA Figure 11-28 EPITHELIOID ANGIOSARCOMA This image illustrates how epithelioid in appearance some angiosarcomas can be, mimicking both poorly differentiated carcinoma and metastatic melanoma.

ANGIOSARCOMA Figure 11-24 ANGIOSARCOMA This image illustrates the frequent finding of varied patterns of differentiation within the same lesion. On the left side of the image, the angiosarcoma could be classified as well-differentiated; on the right side of the image, the growth pattern is solid More about this image found in ANGIOSARCOMA This image illustrates the frequent finding of varied pattern...

ANGIOSARCOMA Figure 11-26 ANGIOSARCOMA A: Low-power view demonstrates a solid sheet of spindle cells with areas of hemorrhage (“blood lakes”). B: High power shows the highly atypical spindle cells with brisk mitotic activity. C,D: ERG (C) and MYC (D) immunostains. Clinical history More about this image found in ANGIOSARCOMA A: Low-power view demonstrates a solid sheet of spindle cells...

angiosarcoma. C: Careful inspection reveals foci in which the spindle cells coalesce into epithelioid aggregates. D: A keratin (CK903) immunostain is strongly positive, confirming the diagnosis of metaplastic carcinoma.
