Q. Why the haemangioma is compressible ?
A. Haemangioma consists of multiple blood-filled
vascular spaces. These spaces communicate with
the surrounding veins. Haemangioma is
compressible because its contained blood empties
into the veins communicating with the
haemangioma.

Q. What are the compressible swellings you
know ?
A. Haemangiomas, lymphangiomas, aneurysms,
pharyngeal pouch, saphena varix, varicocoele,
pneumatocoele, laryngeocoele, tracheocoele and
hernias.

Q. What is the commonest site of a
haemangioma ?
A. The head and neck region.

Q. Does it affect internal organs ?
A. Yes, for example the liver and spleen.

Q. What are the different types of
haemangioma you know ?
A. The different types of haemangioma are :
1. Capillary Haemangioma :
Port wine stain, Strawberry angioma, Salmon

2. Venous Haemangioma (Cavernous
haemangioma)
3. Arterial Haemangioma (Circoid aneurysm)

Q. What is the treatment of a cavernous
haemangioma ?

1. Injection of a sclerosant material
2. Embolization injection
3. Surgical excision
4. Laser radiation

Q. As regards injection sclerotherapy, what is
the commonest material to be used ?
A. Ethanolamine oleate.

Q. What do you mean by embolization
injection ?
A. That is the injection of some material into the
feeding artery of the haemangioma through
angiography to produce occlusion of this artery
and so necrosis of the haemangioma.

Q. What are the famous materials to be used
in this regard ?
A. Gelfoam, alcohol foam and silicon particles.

Q. What is a hamartoma ?
A. A hamartoma is "a developmental tumour-like
malformation characterized by being formed of the
same tissues particular to the part of their origin
and these tissues are arranged in a haphazard
fashion. It is also characterized by a rate of
growth similar to the surrounding structures".

A.
1. Haemangiomas 2. Lymphangiomas

5. Elephantiasis neuromatosa

Q. Mention the types of benign pigmented
naevi (moles) ?

2. Junctional naevus
3. Compound naevus
4. Blue naevus
5. Juvenile naevus
6. Congenital giant naevus
7. Halo naevus
8. Spindle cell naevus
9. Naevus of Ota
10. Naevus of Spilus
11. Lentigo

Q. At what age do benign pigmented naevi
start to appear ?
A. They present in childhood and adolescence,
rarely they present at birth.

Q. What are the characteristic features of
congenital giant naevus ?

areas of the body, usually hairy, and what is more
