Transcript of "Red blue lesion 212"

  1. 1. Red blue lesion By Abdulrahman al sulaiman Saleh al abbas Khalid al ahmary Tariq al mutair
  2. 2. Why
  3. 3. Intravascular      Congenital Reactive Neoplasm Metabolic immunologic
  4. 4. congenital: haemangioma       Increased in number of capillaries Benign tumours of infancy Characterized by: Growth phase with endothelial cell proliferation of large (cavernous) or small (capillary) vascular channels Diagnosed at first 8 weeks of life 3 female vs. 1 male
  5. 5. .Cont     Site : most common in head and neck Shape : pale macula with thread like telangieclasis Superficial skin lesion appear raised and bosselated Firm and rubbery to palpation
  6. 6. treatment Spontaneous involution during early childhood 
  7. 7. Congenital : vascular malformation   Structural anomaly of blood vessel without endothelial proliferation Present at birth and persist throughout life and grow with individual
  8. 8. .Cont    Capillary form : Part wine spot are common Later in life lesion darken & becomes nodular due to ectasia
  9. 9. .Cont     Venous form : Blue in colour Compressible Swelling associated with increase venous pressure
  10. 10. .Cont      Anteriovenous form : Persistent direct arterial & venous communication : Palpable thrill Overlying skin is hot to touch pain, bleeding and skin ulceration
  11. 11. Sturge-weber syndrome Encephalotrigeminal angiomatosis - Venous malformation involving leptomeninges of cerebral cortex - assocciated facial lesion known as port-wine stain - vascular lesion of encephalotrigeminal angiomatosis may extend to oral cavity - neurologic effects of encephalotrigeminal angiomatosis may include: mental nerve seizure disorder
  12. 12. Rendu-Osler Weber Syndrom Hereditary hemorrhagic telangiectasia  Multiple hemangiomas  Autosomal dominant transmitted manner  Abnormal vascular dilation of terminal vessels  Clinical features : Age : appear early in life and persist through adulthood . Shape : red macules or papules . Site : face, chest and oral mucosa .
  13. 13. .Cont Complications : Intranasal lesions. Intraoral lesions . Chronic low-level bleeding .  Histopathology : Capillary and cavernous types similar to other hemangiomas . 
  14. 14. treatment Of vascular lesion are Surgical Laser therapy   
  15. 15. Varix & other vascular malformations     It is a type of acquired vascular malformation . A fairly-common condition of older people . Distended blood vessels are observed on the lingual tongue surface . Syndrome : lingual varices .
  16. 16. Pyogenic Granuloma Etiology Injury or stimulus (EX : calculus ) . Hormonal changes .  This well lead to : Modified gingival reparative mechanism . Prolifration of CT rich with capillaries .
  17. 17. .Cont Clinical features : Shape : red broad based mass . Age : any age . Sex : female > male Site : gingiva 
  18. 18. treatment Remove of the etiological factor calculus,hormonal) surgical remove  )
  19. 19. Periphral giant cell granuloma Etiology: .Unusual hyperplastic CT response to injury .Leads to : reparative process containing multinucleated giant cells  Clinical features: Site : gingiva Origin : PDL . Shape : red blue , broad based mass and may ulcerate Age : any age Sex : female > male  Radiographically : result in erosion of cortical bone 
  20. 20. treatment Remove of the etiological factor calculus,hormonal) surgical remove  )
  21. 21. Scarlet Fever Systemic bacterial infection can lead to capillary damage .  Clinically : Pharyngitis , Tonsillitis, fever, lymphadenpathy and headache Red face Tongue cover with white coat & enlarged fungiform papilla (strawberry tongue) After the white coat is lost (raspberry tongue)
  22. 22. (Erythroplakia ( Red Patch Significantly higher incidence than leukoplakia Lesion appear as well defined red patch . Site : floor of the mouth, tongue and retromolar mucosa Age : 50:70 Sex : no predilection  Histopathology : - Epithelial dysplasia - Relative reduction in keratin production - Increase in vascularity 
  23. 23. Treated with surgery if possible
  24. 24. Neoplasms: kaposi’s sarcoma     Etiopathogenesis: Human harpesvirus 8 Kaposi’s sarcoma herpesvirus Aids associated
  25. 25. .Cont      Clinical features : Classic form ( indolent form & poor prognosis ) Older male Multifocal reddish brown nodules Affect skin and lower extremities
  26. 26. cont Endomic form : Common in black population  Immunodeficiency form ( rapid aggressive & poor prognosis ): Multifocal skin lesion not limited to extremities Oral and lymph node lesion are common Involve visceral organs Younger age group 
  27. 27. .cont      Histopathology features : Hypercellular foci Defined vascular channels Extarvasated RBCs Later may superficially resemble pyogenic granulomas
  28. 28. Metabolic vitamin b complex deficiencies       Etiopathogenesis : Decreased intake of vitamin b Clinical feature : Oral changes pain, burning sensation ,lip fissuring …est Keratitis of the eye Scaly dermatitis on nasolabial area
  29. 29. Vitamin b12 deficiency ((pernicious anaemia Clinical feature : Adult Weakness .pallor, shortness of breath and fatigue Headache, dizziness Nausea , diarrhoea& stomalitis Oral manifestation : Glossitis due to atrophy of the papillae 
  30. 30. Plummer vinson syndrome ((iron deficiency Clinical feature : Weakness , pallor, shortness breath ,brittle nails & hair atrophy of upper GIT and glossitis 
  31. 31. Burning mouth syndrome Etiologic : Micro organisms fungi, bacteria Xerostomia Vit . B . Iron& zink deficiency Diabetes mellitus 
  32. 32. Clinical feature Middle age Altered taste Tongue is most involvement site 
  33. 33. Plasma cell gingivitis Etiology : Chewing gum may provide allergic reaction . Hypersensitivity reaction to certain dietary components .  Clinical features : Common in adults, occasionally affect children . No sex predilection . Sudden onset, no systemic complains . Fairly red attached gingiva but not ulcerated . Burning tongue, lip & mouth . 
  34. 34. .Cont Histopathology : - Spongioutic epithelium . - Mixed inflammatory cell infiltrate . - Densely prominent capillaries in lamina propria . 
  35. 35. EXTRAVASCULAR LESIONS  - PETECHIAE & ECCHYMOSIS Etiology : Intraoral, due to blood disease .  leukemia  platelets defect  - hemophillia and related disorders . Trauma .
  36. 36. .Cont  Clinical features : Color depend on duration (red-blue-purple). Soft tissue lesions occur in traumatic areas . Hemorrhagic lesions occur spontaneously .
