Background: Progressive cribriform and zosteriform hyperpigmentation (PCZH) is a disorder of pigmentation. Although several cases of PCZH have been reported, cases that associated with vitiligo have not been published in the past. Aim: We report the case to reveal the interesting mosaicism reflecting on the skin. Case Presentation: This case presents a phenomenon of the coexistence of hyperpigmentation and depigmentation arranged in unilateral and symmetric distribution in one patient. Conclusion: The aetiology of the pigmental disorders is still unknown. The linear nature of the pigmented bands probably reflects the clonal migration and proliferation of embryonic melanoblasts, so somatic mosaicism that develops during embryogenesis appears to be the underlying aetiology, which is leading to proliferation and migration of two mixed populations of melanocytes with different potential for pigment production.

Pyrolysis properties of lignin separated from four different kinds of wood （fir, larch, poplar, and eucalyptus） compared with commercial lignin were investigated using a thermogravimetric analyzer coupled to a Fourier-transform infrared spectrometer（TG-FTIR）. Kinetic parameters of lignin thermal cracking reaction, such as activation energy and pre-exponential factor, were calculated using a three-dimensional diffusion model. The carbon residue rate and activation energy of softwood lignin were higher than those of hardwood lignin, showing that the decomposition of the former is relatively more dif？cult than that of the latter during pyrolysis. The distinct characteristic peaks of small-molecule gases and oxygenated chemicals such as ethers, phenols, acids, aldehydes, and alcohols were observed near the maximum weight loss rate by analyzing the 3D IR spectrum of the gas phase products. The formation routes of the main gaseous products were discussed, and the following order of releasing amounts was noted： CO2〉CH4〉H2O〉CO. It is believed that these results will provide valuable information for the thermo-chemical conversion process of lignin from the point of view of feedstock.
