  9. 1- DERİNİN SELİM TÜMÖRLERİ 5- Pigmented Lesions : - Naevi (compount,, Junctional, dermal)) - Solar Lentigo

  10. premalignant lesions • 1- Keratosis • Actinic Keratosis Radiation Keratosis • Solar Keratosis Skin horn • 3- Chemically inductive Keratosis • 3- Epithelial tumors • Keratoacanthoma Trycoepithelioma • Fibro-epithelioma Sebaseous Nevus • Cylindroma • 4- Inheridet Conditions • Xeroderma pigmentosum • Epidermolisis Bullosa

  11. premalignant lesions 5- Trauma and Scars Chronic wounds Chronic Fistulas Unstable burn scars Lupus Vulgaris 6- Mucosal lesions Leukoplakia 7- Others Liken Planus

  12. Actinic keratosis • (senile keratosis) must be distinguished from the seborrheic keratosis because it represents dysplastic epithelium and is a premalignant lesion. • The actinic keratosis is found primarily on exposed surfaces as discrete, flat, or slightly elevated lesions with hard, dry adherent hyperkeratosis and underlying erythema. • These lesions are often numerous in elderly people with weather-beaten skin

  13. Keratoacanthoma • It is a rapidly growing papule that enlarges to 1 cm to 2 cm within a period of several weeks • The round, smooth, pink nodule encircles a massive keratinous plug. • Histologically, the keratoacanthoma may be difficult to distinguish from a squamous cell carcinoma,

  14. Xeroderma Pigmentosum Xeroderma pigmentosum is a relatively rare systemic disease Transmitted through an incomplete sex-linked recessive gene. The disease, which has its onset during early childhood, is characterized by extreme sensitivity to sunlight. Initially, diffuse lentigos are noted, with progressive drying and thinning of the skin.

  15. Xeroderma Pigmentosum The primary deficiency is that of the enzyme endonuclease, which is needed to repair sunlight-damaged DNA. Malignant degeneration into is noted during early adult life, with death due to metastatic disease. Prolongation of life is possible by absolute protection from sun exposure and continual aggressive treatment of all developing tumors. The prognosis is dismal.

  16. Malignant Tumours of The Skin • Basal Cell Carsinoma (BCC) • Squamous Cell Carsinoma (SCC) • Malignant Melanoma (MM)

  17. Basal Cell Carcinoma • Basal cell carcinoma is the most common malignancy of whites, arising from cells of the basal layer of the epithelium or from the external root sheath of the hair follicle

  18. SKIN CANCER : aetiology and stimulators • exposure to ultraviolet radiation (UV) • ionising radiation • chemical carcinogens • viral carcinogens • Chronic wounds, fistulas and unstable burn scars • repeated irritating microtraumas • inherited conditions such as xeroderma pigmentosum • premalignant lesion

  19. Fitzpatrick Deri TipleriDerinin fototip’i derinin içindeki melanin miktarına göre belirlenir

  20. UVB Damages to DNA • UVA causes wrinkles on the skin

  21. Basal Cell Carcinoma • most common above the line “tragus-comissura” • It is directly related to sun exposure, • the etiologic factor being UV radiation. • Basal cell carcinomas occur most often at sites with the greatest concentration of pilosebaceous follicles. • most often in white skined people • Radiosensitive • it almost never metastasises (if diameter less than 10 cm)

  22. Signs of the Skin Cancer: • The wound does not heal with in an appropriate time • Bleeds • The lesion grows slowly • Change of the character of the lesion • a lesion presented with Lymphadenopathy Tüm yaşamda deri kanseri riski 1/5 1980 yılından bu yana %65 artış

  25. Classification of BCC(ACKERMAN): A- LOCALIZED 1- Nodular 2- Nodulocystic 3-Pigmented B- SUPERFICIAL 1-Superficial spreading 2-Multifocal C-INFILTRATIVE 1- Mopheic

  26. History • Etyoloji • Premalign lezyolar • Yaş / cinsiyet • Lokalizasyon • Biopsy • Küretaj • Yüzeyel tıraşlama • Punch biyopsi • Eksizyonel biyopsi Diagnosis:

  27. Deri kanserleri • M.M. en sık rastlanan 8. kanser • M.M.hayat boyunca rastlanma sıklığı 1/200 • M.M. diğer kanserlere göre en hızlı artış gösteren • BCC / SCCA : 4 / 1 • Çocuklukta güneş ışını alımı, sık sık olması • Çocukluktabül oluşturan güneş yanığı olması

  28. Histopathologic confirmation is obtained with a biopsy • Curettage • Shave biopsy • Punch biopsy • Excisional biopsy

  29. TREATMENT • Basal Cell Carsinoma • Cryotherapy • Electrocoagulation • Surgical excision ( 2 - 5 mm ) • Radiotherapy • Local chemotherapeutic drug • Curettage • Superficial shaving • Laser

  30. Squamous Cell Carcinoma • Squamous cell carcinoma originating from the keratinizing or malpighian (spindle) cell layer of the epithelium, is seen primarily in older patients, mostly men

  31. Squamous Cell Carcinoma • most common below the line “tragus-comissura” • the primary etiological factor is solar radiation. • chronic ulcers including chronic lesions, burn wound, osteomyelitis, cytotoxic drugs, • immunosuppressant drug treatment, • a wide variety of dermatoses, discoid lupus erythematosus, and hidradenitis suppurativa play a significant role in the development of the relatively small number of these skin cancers. • Seen most often in black skined people • Radioresistance • Five percent to 10% of squamous cancers metastasize

  32. Tissue transplantation: • Risk of skin cancer is% 35 - 70 over 20 years • The risk of skin cancer: • (SCC: 65-100 times higher than normal population • BCC: 10 times higher • MM: 4 times higher

  33. TREATMENT • Squamous Cell Carsinoma • Surgical excision (1 cm) • Radiotherapy
