NEOPLASMS - Coggle Diagram

- - - - Etiology: risk factors include exposure to ultraviolet light, genetic factors, long-term immunosuppressive, and arsenic ingestion
      - Method of Transmission: genetic predisposition as seen in several syndromes, such as nervous basal cell carcinoma syndrome (may be transmitted to offspring)
      - Characteristics: 85% found in the head and neck with most on the face, presents as a popular growth with a sessile base early, borders of lesions are raised and exhibit a pearly appearance, may be pigmented and resemble a nevus or may have a flat scar-like appearance, lesions are painless
      - Dental Implications: Pt should be referred to an appropriate physician for evaluation
      - Treatment/Prognosis: surgical excision, laser surgery, cryosurgery (freezing w/ liquid nitrogen), electrodesiccation (burning), and radiation therapy; Pt’s who have had one skin cancer have a 50% chance of developing another BCC at a different site within 5 years

    - - Etiology: risk factors include ultraviolet light, arsenic ingestion, radiation therapy, areas that were previously burned, genetics, and skin diseases or injuries that cause scarring; HPV has been associated with SCC in the head and neck region
      - Method of Transmission: NOT transmissible, unless associated with HPV after infection of the virus
        Characteristics: develops in a preexisting actinic keratosis, painless, non healing, rough, erythema, scaly papule, may cause pruritus or itching, lesion enlarges as it becomes indurated, surface eventually becomes ulcerated and crusted and bleeds easily, any non healing lesion should be biopsies and identified
      - Dental Implications: painless lesions, nonnhealing ulcers should be suspected as being SCC and should be biopsied
      - Treatment/Prognosis: surgical excision, laser surgery, cryosurgery (freezing w/ liquid nitrogen), electrodesiccation (burning), radiation therapy, and PDT, Pt should be monitored for new lesions on an annual basis
