Benign Cutaneous Neoplasms1 Flashcards
What age group are seborrheic keratosis most commonly found?
Over 30
What benign skin lesion begins as a demarcated macule and progresses into a ﾓwartyﾔ papule with a ﾓstuck-onﾔ appearance?
Seborrheic keratosis
Light complexion, blue eyes, and early freckling predispose to what pre-cancerous lesion
Actinic keratosis or solar keratosis
True/False: Immunocompromised patients are at an increased risk of developing actinic keratosis
TRUE
True/False: The lifetime risk of actinic keratosis progressing to squamous cell carcinoma is over 10%
FALSE
cutaneous horns are most commonly found in exuberant hyperkeratosis of what primary diagnosis
Actinic keratosis or solar keratosis
What are the treatment options for Actinic keratosis
Cryotherapy, 5-fluorouracil (5-FU), topical imiquimod, and photodynamic therapy
A ﾓdry, adherent scaleﾔ on a flesh colored/erythematous, ill defined macule or papule is characteristic of what benign cutaneous diagnosis
Actinic keratosis or solar keratosis
Keratoacanthomas (benign nodules, over 1cm in diameter, with crater like keratin plugs), progress, then regress, spontaneously ﾖ why is it critical to excise these benign nodules?
They are clinically and microscopically similar to squamous cell carcinomas
Small (under 1cm), firm, dome shaped papules, which are pink to brown in color and feel ﾓattachedﾔ to subcutaneous tissue represent what benign cutaneous neoplasm?
Dermatofibroma
Where are dermatofibromas most commonly found ?
Lower extremities
What is the dimple sign in diagnosing dermatofibroma?
apparent downward movement of the tumor on pinching the lesion, which behaves as it were attached to the subcutaneous
What is the ﾓbutton-holeﾔ sign in neurofibromas ?
Tumor easily invaginates with finger pressure
What disorder is associated with multiple neurofibromatous lesions
Neurofibromatosis (NF-I) or von Recklinghausenﾒs disease
Proliferation of neuromesenchymal tissue forms what benign cutaneous neoplasm
Neurofibromas
