HEMANGIOMA: DEFINITION AND HISTOLOGY
Benign proliferation of endothelial cells Most common neoplasm of the infancy Does not exhibit unlimited growth
potential Types: capillary (small vessel); cavernous
(large vessel); and mixed

ETIOLOGY OF HEMANGIOMAS
Unclear Possible role of angiogenesis is
identified: Excess of stimulating cytokines, or… Decrease in angiogenesis inhibitors
No genetic component is reported

HEMANGIOMA DEVELOPMENT
30% are visible at birth Majority arises between weeks 1-4 Go through slow regression “involution” Involution can last 3-10 years By age 5, 50% of infants no longer have
it

HEMANGIOMA: SUSCEPTIBLE POPULATIONS
Females are 5 times more susceptible Twins Caucasians Low birth weight infants (>2.2 lbs):
26% chance of developing hemangiomas

HEMANGIOMA: CLINICAL APPEARANCE
83% occur in head and neck area Tongue (ventral) is most common
intraoral site Followed by lips and buccal mucosa Variably sized deep red or blue lesions Frequently blanch under pressure

HEMANGIOMA: DENTAL COMPLICATIONS
Usually asymptomatic to the patient Compression of tissues around it Formation of fissures Macroglossia if the tongue is affected Formation of ulcers and hemorrhages Functional and aesthetic problems

HEMANGIOMA: DENTAL CONSIDERATIONS
Keep in mind possibility of severe bleeding
Severe hemorrhage can complicate treatment
Interference with eating, breathing, speaking
Rapid tumor enlargement Early detection and biopsy are
necessary Treatment: sclerotherapy,
corticosteroids, interferon α, laser, embolization, surgery

LYMPHATIC MALFORMATION (LM): DEFINITION AND ETIOLOGY
AKA cystic hygroma, lymphangioma, hemangiolymphangioma
Benign tumor composed of lymphatic vessels
Etiology is unclear Errors of the vascular morphogenesis Most are congenital

OTHER DENTAL COMPLICATIONS
Maxillofacial skeleton dysmorphogenesis Due to pressure effects and high blood
flow Speech pathologies Abnormal mobility and morphology of
tongue Palatal hypomobility Neonate feeding difficulties Complications from surgical treatment

ADVICE FROM A DENTAL PROFESSIONAL
Due to multiple dental complications of LM,aggressive dental care is indicatedmeticulous oral hygiene is emphasizedmore frequent dental recall appointmentspediatric DDS should be involved early for
LM children

STURGE-WEBER SYNDROME: DEFINITION Congenital neurological disorder Seizures Large unilateral port-wine stain on
forehead Covers upper eyelid also Caused by overabundance of capillaries
around nerve V Loss of nerve cells in the area of the
stain

SWS: DENTAL COMPLICATIONS
Teeth might come in early or late Gingival hypertrophy is common Periodontal management is often
recommended Prior to any invasive surgery, MRI/MRA
or CAT of the face are indicated Meticulous oral hygiene is emphasized

ORAL VASCULAR MALFORMATIONS: A PERSONAL TOUCH
My aunt Liliya’s face has been disfigured by a large unilateral port-wine stain: R cheek, eye
When she moved to Germany, laser surgery has corrected the port-wine stain appearance
Former Russian president, Mikhail Gorbachev, has been affected by a port-wine stain
