Question:

Regarding the composition of angiolipomas chose the correct answer.
1. Calcium is frequently found in this tumor.
2. The tumor is exclusively composed of fatty tissue.
3. Vascular structures can be identified inside the tumor.
4. No vascular structures can be identified inside the tumor.
5. Fibrin clots are not found inside the lesion.





Answer:

The correct answer for the question "Regarding the composition of angiolipomas chose the correct answer." is:

3. Vascular structures can be identified inside the tumor.



Explanation
A. [Histologically calcium is not frequently found inside the tumor.]

B. [Histologically, angiolipomas are not exclusively composed of adipose tissue.]

C. [Histologically, they are composed of mature adipose tissue and a proliferation of blood vessels with fibrin clots inside vascular channels.]

D. [A proliferation of blood vessels is found inside the tumor.]

E. [Histologically, fibrin clots inside vascular channels can be found inside the tumor.]

Abstract
Angiolipomas are benign lesions that are frequently found in subcutaneous cellular tissue, but are rarely located in the gastrointestinal tract. Here we discuss a case of colonic angiolipoma that presented as a mass near the hepatic flexure, occupying approximately 90% of the colonic lumen. The diagnosis was made by endoscopy and computed tomography. The mass was resected successfully and diagnosis was confirmed by histological studies and immunohistochemical tests.
