Primary skin lesions are initial, direct manifestations of a disease process. Bulla is a primary lesion (a large blister - like elevation). Lichenification (thickening of skin), Scales (flaking skin), and Erosion (partial - thickness skin loss) are secondary lesions, resulting from changes to primary lesions or other processes.

Cimex lectularius is the scientific name for bed bugs. Pemphigus is a skin disease, chiggers are Trombiculidae larvae, and papillomatosis involves growths like warts. So the common name for Cimex lectularius is bed bugs.
