Abstract:
BACKGROUND Extrapulmonary small cell carcinoma (SmCC) is a relatively rare clinical entity constituting only 2.5-5% of SmCCs. Recently, evidence has emerged that high-risk types of human papillomavirus (HPV) might play an etiologic role in oropharyngeal SmCC, similar to squamous cell carcinoma. CASE REPORT Here, we present a case of tonsillar SmCC that presented as combined SmCC-squamous cell carcinoma in a cervical lymph node, raising the possibility that the SmCC-component represents disease progression. CONCLUSIONS This case lends further support to the importance of HPV in the development of oropharyngeal SmCC and suggests a mechanism of disease progression.

Cell Potential and Free Energy
Thermodynamics is the branch of physics dealing with the relationship between heat and other forms of energy. In an electrochemical cell, chemical energy is converted into electrical energy.
Thus, a link can be predicted between cell potential, free energy change, and the equilibrium constant for the reaction. Cell potential can also be measured as the oxidant or the reducing strength, and similar acid-base strength measures are reflected in equilibrium...
