Evaluation of mycosis fungoides with reflectance confocal microscopy / 中华皮肤科杂志

ABSTRACT

Objective To investigate the reflectance confocal microscopy (RCM) features of mycosis fungoides (MF).Methods Four male and two female patients with MF,who were aged 7-73 years with a clinical course of 1-5 years,were collected from June 2011 to May 2012 in the department of dermatology.Of the six patients,two were in patch stage,three in plaque stage,and one in tumor stage.All the cases were confirmed by histopathological,immunohistochemical and relevant examinations.For each patient,three lesions were selected and investigated using RCM,and one of the three lesions was subjected to histopathological examination.Results RCM features of MF included hyperkeratosis,disarray of honeycomb of stratum spinosum,reduced refractivity of dermal papillary rings,roundish or round scattered hyperrefractive cells in the epidermis,infiltration of a small quantity of inflammatory cells in the papillary dermis.Occasionally,some round to oval hyporefractive cells aggregated to form vesicle-like structures.These RCM features correlated well with histopathologic findings.Conclusion Combined with clinical manifestations,RCM may serve as a noninvasive auxiliary tool for the diagnosis of MF.
