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 14. Port-wine stain 15. To revise again

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. 22. Plexiform Haemangioma (Arterial
Haemangioma) 23. To revise again Heamangioma Capillary venous
arterial 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 30. lymphangioma cystic hygroma 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 44. TUBULO-DERMOID 45. To
