[Spirochetes in the cheilits granulomatosa and sarcoidosis].

Homogenate of seven cases of cheilits granulomatosa (CG), one case of Melkersson-Rosenthal syndrome (MRS) and one case of sarcoidosis (Sar) were found to have Borrelia underdark field microscope. CG culture of lip tissue of 2 cases showed Borrelia. Detection of anti-Borrelia Burgdorferi (BB)-antibody in serum showed that 8 (82%) of 11 cases of CG were positive, 3 (75%) of 4 cases of MRS and one case of Sar were positive. Histopathological changes in all cases were consistent with the pathological changes caused by spirochetes infection. The results confirmed that there is Borrelia in CG, MRS and Sar, which are spirochetes infected diseases.
