Abstract
Thin sections of molluscum contagiosum lesions from man were examined with the electron microscope. Cells were seen in the prickle cell layer of the epidermis which contained only a very few cytoplasmic elementary bodies and were considered to be early infected cells. Others were found with varying numbers of elementary bodies scattered through the cytoplasm and still others were entirely filled with elementary bodies forming a mature inclusion. Elementary bodies in the early infected cells differed somewhat in shape from most of those seen in the larger inclusions. The mature inclusion bodies were divided into locules by septa. The locules contained mature elementary bodies which appeared to form from the material composing the matrix of the septa by a process of segmentation and condensation. The elementary bodies when sectioned ap-peared in some instances to have a formed cortex and a less dense interior.
