PITYRIASIS LICHENOIDES CHRONICA, PITYRIASIS LICHENOIDES
Pityriasis lichenoides chronica (PLC) is the chronic form in the spectrum of pityriasis lichenoides [The etiopathogenesis of PLC remains uncertain with three major theories being proposed: a lymphoproliferative, an infectious; and an immune complex mediated theory [To date, there is no standard treatment of PLC. Several lines of treatments have been tried with variable results including topical agents, antibiotics and immunosuppressives. Combination therapy is considered the best approach by some authors [The aim of this study was to assess the therapeutic efficacy of azithromycin in comparison with NB-UVB in PLC patients and investigating the presence of streptococcal infection in PLC patients and its therapeutic implications.
