Searches for fermiophobic Higgs boson decaying into photon or weak boson pairs have been performed at LEP with the data collected at center of mass energies up to 209 GeV. A summary of several analyses allowing to cover some hundred different final state topologies is presented. No statistically significant evidence of fermiophobic Higgs boson has been found. A lower limit on the Higgs boson mass is presented. More generally, anomalous couplings of the Higgs boson are searched for through the processes e+ e− → H0 γ , e+ e− → e+ e− H0 and e+ e− → H0 Z by the L3 collaboration. The Higgs decay channels H0 → ff, H0 → γγ , H0 → Zγ and H0 → WW(∗) are considered and no evidence is found for anomalous Higgs production or decay and limits are put.
