We have measured the resistance of some Bi2Sr2CaCu2O8 superconducting single crystals along ab plane and the c axis. In some single crystals, a remarkable resistivity anomaly near the superconduct ing transition temperature is observed in the ab plane. The peak is suppressed a nd vanishes gradually with increasing applied magnetic field (>100Gs) or transpo rt current. We proposed that the resistance peak is a quasi-reentrant behavior d ue to the inhomogeneous distribution of the superconducting phase.
