Haemangioma , lymphangioma and dermoid cyst

  1. 1. Haemangioma Lymphangioma Dermoid Cyst Dr Mohamed Elmetwally

  3. 3. Haemangioma
  4. 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. 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. 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. 7. Capillary Haemangioma
  8. 8. Common capillary haemangiomas are: • Salmon Patch • Port-wine Stain • Strawberry Angioma
  9. 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. 10. Strawberry angioma
  11. 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. 12. Salmon patches
  13. 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. 14. Port-wine stain
  15. 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. 16. To revise again Common capillary haemangiomas are: • Salmon Patch • Port-wine Stain • Strawberry Angioma
  17. 17. Cavernous Heamangioma
  18. 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. 19. Cavernous haemangiomas
  20. 20. Cavernous haemangiomas
  21. 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. 22. Plexiform Haemangioma (Arterial Haemangioma)
  23. 23. To revise again Heamangioma Capillary venous arterial
  24. 24. Lymphangioma
  25. 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. 26. Lymphangioma • Classified into: • Capillary • Cavernous (cystic hygroma)
  27. 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. 28. lymphangioma
  29. 29. lymphangioma • Cavernous lymphangioma is the famous lesion called cystic hygroma which is discussed in “Head and Neck surgery”
  30. 30. lymphangioma cystic hygroma
  31. 31. DERMOID CYST
  32. 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. 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. 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. 35. • EXTERNAL AND INTERNAL ANGULAR DERMOID ( fusion line of frontonasal and maxillary processes) • SUBLINGUAL DERMOID • PRE –AURICULAR DERMOID • POST AURICULAR DERMOID
  36. 36. Sequestration Dermoid
  37. 37. Sequestration Dermoid
  38. 38. Sequestration Dermoid
  39. 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. 40. IMPLANTATION DERMOID
