3. Haemangioma

4. Definition
The term hemangioma was originally
used to describe any vascular tumor-like
structure, whether it was present at or
around birth or appeared later in life

5. Definition
• Now, these conditions are categorized into
two families:
1. a family of self-involuting lesions that
eventually disappear.
2. another family of malformations, enlarged
or abnormal vessels present at birth and
essentially permanent

6. Classification
• Haemangioma are of three types based on the
type of vessel involved. They are:
• Capillary Haemangioma
• Cavernous Heamangioma (also called Venous
Haemangioma)
• Plexiform Haemangioma (also called Arterial
Haemangioma

7. Capillary Haemangioma

8. Common capillary haemangiomas are:
• Salmon Patch
• Port-wine Stain
• Strawberry Angioma

9. Strawberry angioma
• The lesions may be present at birth, or may
develop in the first few weeks after birth.
• They develop into a raised dimpled
(strawberry-like) lesion.
• The lesions typically grow in size as the child
grows, until the age of approximately 3-4
years, when they start to regress
spontaneously.
• This process can take up to 10 years

10. Strawberry angioma

11. Salmon patches
• Salmon patches are pink or red, flat,
irregularly shaped patches that appear on the
baby's face or the back of the neck. On the
face, they are commonly found between the
eyebrows or on one of the eyelids.
• Salmon patches are never painful or itchy.
• Salmon patches are always present at birth
• salmon patches typically improve on their
own.

12. Salmon patches

13. Port-wine stain
• port-wine stain or nevus flammeus appears at
birth
• port-wine stain ordinarily persist throughout
life.The area of skin affected grows in proportion
to general growth.
• Port-wine stain occur most often on thebut can
appear anywhere on the body, particularly on the
neck and upper trunk.
• Early stains are usually flat and pink in
appearance. As the child matures, the color may
deepen to a dark red or purplish color

15. To revise again
• Haemangioma are of three types based on the
type of vessel involved. They are:
• Capillary Haemangioma
• Cavernous Heamangioma (also called Venous
Haemangioma)
• Plexiform Haemangioma (also called Arterial
Haemangioma

16. To revise again
Common capillary haemangiomas are:
• Salmon Patch
• Port-wine Stain
• Strawberry Angioma

17. Cavernous Heamangioma

18. Cavernous haemangiomas
• Cavernous haemangiomas can arise nearly
anywhere in the body
• Cavernous haemangioma is a collection of
dilated blood vessels forming a tumor.

19. Cavernous haemangiomas

20. Cavernous haemangiomas

21. Plexiform Haemangioma (Arterial
Haemangioma) or Circoid Aneurysm
• A cirsoid aneurysm is the dilatation of a group
of blood vessels due to congenital
malformations with AV (arterio venous)
shunting in relation to an artery
• The superficial temporal artery is the most
commonly involved artery.

Haemangioma)

24. Lymphangioma

25. Lymphangioma
• Lymphangiomas are malformations of the
lymphatic system.
• These malformations can occur at any age
and may involve any part of the body, but 90%
occur in children less than 2 years of age and
involve the head and neck.

26. Lymphangioma
• Classified into:
• Capillary
• Cavernous (cystic hygroma)

27. lymphangioma
• Capillary lymphangioma may be :
• Localized sweelling ( lymphangioma
circumscriptum) or,
• Diffuse swelling in the form of macrochelia
(swollen lip) or macroglossia (sowllen tongue)

28. lymphangioma

29. lymphangioma
• Cavernous lymphangioma is the famous lesion
called cystic hygroma which is discussed in
“Head and Neck surgery”

31. DERMOID CYST

32. • Cyst lined by squamous epithelium containing
desquamated cells
• CONTENTS
mixture of sweat, sebum, desquamated
epithelial cells, hair
Types :
1. Sequestration
2. Implantation
3. Tubulodermoid
4. Teratomatous

33. CLINICAL TYPES
• CONGENITAL / SEQUESTRATION DERMOID
SITE: along lines of embryonic fusion (midline
of body or face)
FORMATION: dermal cells sequestrated in
subcutaneous plane then proliferate & liquify
forming a cyst

34. CLINICAL FEATURES
• Manifests in childhood or adolescence
• Typically a painless slow growing swelling
• Soft, cystic, fluctuant, yield to pressure of
finger and will not slip away
• Underlying bony defect – clue to diagnosis
• Location along line of fusion

35. • EXTERNAL AND INTERNAL ANGULAR
DERMOID ( fusion line of frontonasal and
maxillary processes)
• SUBLINGUAL DERMOID
• PRE –AURICULAR DERMOID
• POST AURICULAR DERMOID

36. Sequestration Dermoid

37. Sequestration Dermoid

38. Sequestration Dermoid

39. OTHER TYPES
• IMPLANTATION DERMOID
1. in women, tailors, agriculturists who
sustain repeated minor injuries
2. sharp injury- epidermal cells implanted in
subcutaneous plane- dermoid cyst
3. fingers, palm, sole of foot

40. IMPLANTATION DERMOID

41. • > arise from totipotent cells
> ectodermal, mesodermal, endodermal
elements
> ovary, testis,retroperitoneum, mediastinum

42. TERATOMATOUS DERMOID

43. TUBULO-DERMOID
• thyroglossal cyst and branchial cyst
