The difference between lysogenic and lytic cycles is that, in lysogenic cycles, the spread of the viral DNA occurs through the usual prokaryotic reproduction, whereas a lytic cycle is more immediate in that it results in many copies of the virus being created very quickly and the cell is destroyed. (wikipedia.org)
The superficial keratinocytes ultimately are shed with the stratum corneum, so no lytic phase exists in the HPV life cycle, as the apoptotic keratinocytes release the virus during degradation in the mucosal lumen (see the image below). (medscape.com)
