Proliferative verrucous leukoplakia (PVL) is an aggressive form of oral leukoplakia with multifocal presentation, high rates of recurrence and malignant transformation. Although development of regional lymph node metastasis is relatively frequent in patients with oral squamous cell carcinoma, axillary metastasis is quite uncommon. This paper presents a case of a 64-year-old female patient who was diagnosed with PVL and developed five oral squamous cell carcinomas and later an axillary lymph node metastasis.

Introduction: Bioelectrography measures the emission of photons and electrons from live beings, and it is possible to assess peoples’ health condition through it. Objective: to compare women with breast cancer (BC), healthy sedentary women (HS) and healthy runners women (HJ) concerning emotional pressure, yin percentage (yin%) and yang percentage (yang%) through electrobiographic photos (EB). Methods: EB were collected from all of the ten fingertips from 11 sedentary women diagnosed for BC (G12), aged 59±11 years; 18 sedentary women with no BC records (G3), aged 46±15 years; and 8 runners women with no BC records (G4), aged 45±9 years. EB were obtained and processed through Bio Well hardware and software, and later had been statistically analyzed through software IBM SPSS Statistics 23. Results: higher levels of emotional pressure (EP) were observed in G4 regarding G3 and G12. Greater levels of yang% and smaller levels of yin% were observed in G12 regarding G3 and G4 Conclusion: the present study points out the possibility of using bioelectrography as an option for detecting EP increasing inductive situations, as well as for those levels quantification, verifying the procedures presenting best results for EP control. Also becomes clear the possibility of using bioelectrography for measuring yin-yang percentage both in installed pathologies or as prophylaxis previously to clinical symptoms such as assessing balance between oncogenesis (yang) and suppressive genes (yin). Once this balance is set, cancer trunk cells growth will be under control avoiding cancer, cancer relapse or even its metastasis.
