(P4) Cardiac: Capillary hemangioma (the skin) Flashcards
Identify:
Capillary hemangioma (the skin)
- fatty tissue
- tumor cells
- benign capillary hemangioma
- septa
- skin of lower extremities
- orbit and preorbital area
- angiosarcoma/hemangiosarcoma
- Identify slide:*
- describe the lesion, where is it found?*
Capillary hemangioma (the skin)
- -Below the epidermis*
- -Common congenital vascular lesions*
- -Skin, subcutaneous tissues, mucous membranes of the lips and mouth, and internal viscera (spleen, kidney, liver)*
identify this lesion:
is it malignant or benign?
Benign capillary hemangioma of the skin: many vascular channels, some filled with RBCs
-Their true origin is uncertain, and they represent either true neoplasms or hamartomas (masses of mature but disorganized cells and tissues characteristic of the particular organ)
Identify slide:
Q. what is this lesion composed of?
Capillary hemangioma (the skin)
- Is composed of vascular channels that have the size and structure of normal capillaries
- -They vary from few millimeters to several centimeters in diameter.*
- -Their color is bright red to blue*
- Capillary hemangioma (the skin)*
- Provide 2 examples of TYPES:*
Types
Capillary – small capillary-sized space
Cavernous – large, dilated vascular space
Capillary hemangioma (the skin)
What is the malignant couterpart of Capillary hemangioma?
hemangiosarcoma
Q. What is the most common type of
Vascular tumor?
Capillary hemangioma (the skin)
Capillary hemangioma (the skin)
What two lesions are compared and which one has presence of erythrocytes?
Hemangioma vs Lymphangioma
Lymphangiomas are benign lymphatic vessel hamartomas typically found in the skin or subcutaneous tissue of the head and neck. Although mostly seen in a congenital context, acquired forms have been reported.
Cavernous hemangiomas are benign hamartomas of endothelial origin.

What type of lesion is primarily found
on skin of lower extremeties?
Kaposi Sarcoma Kaposi sarcoma (KS)
is a cancer that causes patches of abnormal tissue to grow under the skin, in the lining of the mouth, nose, and throat, in lymph nodes, or in other organs.
These patches, or lesions*, are usually *red or purpl*_e. They are made of cancer cell_*s, blood vessels, and blood cells
What causes Kaposi sarcoma?
caused by an i_nfection with a virus called human herpesvirus 8_, which is also known as _Kaposi sarcoma-associated herpesvirus (KSHV)_.
The virus, which is in the same family as
Epstein-Barr virus
