[Teseus phenomenon: a new symptom]

Morphological proof of a new phenomenon is presented: moderately activated phagocyte (alveolar macrophage, neutrophil leucocyte) remains connected with a site of its movement by a thin thread. The latter represents a thin tube consisting of sarcolemma substance and contains retractile elements. Thread-like structure gives the phagocyting cell the possibility to return and to reach the major routes of the host--this is a way by which the normal tissue is cleaned up under conditions close to the physiological norm. The phenomenon reminds method used by Teseus for searching exit from the labyrinth after his victory over Minotaurus.
