The word "leucocytoplania" may seem intimidating at first glance, but it can be broken down phonetically. The first part, "leuco," comes from the Greek word for "white." The next part, "cyto," refers to a cell or group of cells. Finally, "plania" comes from the Greek word for "wandering." So, overall, "leucocytoplania" refers to the abnormal wandering of white blood cells. In IPA phonetic transcription, it is written as /lu:kəʊˌsaɪtəʊˈpleɪnɪə/.
Ths wandering of leucocytes out of the blood-vessels or through the tissues.
