Sometimes, journeys are not termed "true migration" because they are irregular (nomadism, invasions, irruptions) or in only one direction (dispersal, movement of young away from natal area).
Malignant properties of lung polyp cells, such as metastasis, tissue invasion, irregular tumor growth, tissue remodeling and inflammation, are linked with reformed proteolysis [3, 22].
Focal or diffuse disruption of the normal low signal intensity muscle wall, resulting in a nodular or irregular appearance, suggests muscle invasion of the bladder or rectum.
Collectively, it is common opinion that mastectomy renders radiation therapy unnecessary unless the tumor is 5 cm or larger, its margins are irregular with signs of invasion through basal membranes of adjacent normal mammary tissue, or if there is nodal metastasis.
The fracture appeared to he uniting, but the fracture line on the body fragment was irregular and worm-eaten, indicating invasion and absorption by tissue from the distal fragment.
Furthermore, when the same number of cells (1 × 10) was injected into BALB/c nude mice, the contour of the tumors yielded from the lower chamber cells was irregular and grown in the invasion way; additionally, the volume of the tumor originated from lower chamber cells was larger than their parallel Panc-1 cells).
Furthermore, there appeared to be no clear distinction between the proliferative and hypertrophic zones of the growth plate and the vascular invasion front was also irregular.
Narrowing of the vessel lumen, abrupt vessel cut-off, and focal irregular indentation are features of vascular invasion on MRA [ 55].
In conclusion, the iGels may be used in treating irregular small bone defects with minimal clinical invasion as well as for bone cell delivery.
They tend to have irregular margins with heterogeneous enhancement and vascular invasion.
