DANGER SIGNALS!!

  • NO CAUSE
  • CAUSATIVE AGENT CARCINOGEN
  • LOCATION
  • ULCERATION, INDURATION,

REDNESS (ERYTHROPLAKIA)

HYPERKERATOSIS HYPERKERATOSIS- VARIATIONS

  • SOLAR CHEILITIS
  • NICOTINE STOMATITIS
  • SNUFF DIPPERS POUCH

IDIOPATHIC LEUKOPLAKIA MUST BE BIOPSIED! Brush “Biopsy” We’ll talk about this at the end of the course when we discuss various new diagnostic techniques.

LEUKOPLAKIA

MALIGNANT TRANSFORMATION

Non-smokers 24%

Smokers (continuous) 16%

Smokers (quit) 12%

Silverman, Gorsky, Lozada Cancer 53:563-568, 1984 LEUKOPLAKIA

In the absence of tobacco as an

irritating, causative agent, there

may be a more lethal initiating or

potentiating factor.

Silverman, Gorsky, Lozada Cancer 53:563-568, 1984

ERYTHROPLAKIA

90% dysplasia or squamous cell carcinoma ERYTHROPLAKIA 91% are either:

  • Invasive carcinoma
  • Carcinoma in situ
  • Severe epithelial dysplasia Shafer & Waldron Cancer 36:1021-1028, 1975 The persistence of erythroplastic lesions for more than 14 days without obvious cause requires biopsy. Mashberg, et al. Cancer 32:1436-1445, 1973

SPECKLED ERYTHROPLAKIA ALMOST ALWAYS CARCINOMA IN SITU OR SQUAMOUS CELL CARCINOMA Asymptomatic, early squamous cell carcinoma 90.5% had a red component 62% had a white component 78% of these were patchy or stippled Mashberg, et al. Cancer 32:1436-1445, 1973 DANGER SIGNALS!!

  • NO CAUSE
  • CAUSATIVE AGENT CARCINOGEN
  • LOCATION
  • ULCERATION, INDURATION,
