| often the initial lesion before the patient or nature has had the chance to change it (by scratching, medication, etc.) | Primary lesions |
| often the "modifications" of the primary lesion | Secondary lesions |
| flat, non-palpable, <1 cm circumscribed discoloration (solar lentigo) | macule |
| a macule >lcm (vitiligo) | patch |
| solid, elevated lesion <lcm (milium) | papule |
| a papule> lcm (psoriasis) | plaque |
| a palpable, solid, round or ellipsoidal lesion with increased dermal involvement; depth differentiates this from a papule (dermatofibroma) | nodule |
| general term for any mass; indicates a large nodule (lipoma) | tumor |
| circumscribed, elevated, pus-containing lesion (acne) | pustule |
| elevated, fluid-containing lesion up to lcm (herpes) | vesicle |
| a vesicle> lcm (bullous pemphigoid) | bulla |
| solid, elevated, rounded or flat-topped lesion form by local, superficial, transient edema (hives/urticaria) | wheal |
| plug of sebum and keratin in a pilosebaceous (hair) follicle (acne) | comedo or blackhead |
| linear lesion produced by an intracutaneous animal or parasite (scabies) | burrow |
| accumulation of stratum corneum in perceptible flakes | scale |
| hardened deposits when serum, blood or purulent exudate dries on skin surface; characteristic of bacterial, infections | crusts |
| loss of epidermis and part of dermis; heals with scarring | ulcer |
| thickened skin with exaggerated skin lines often produced by rubbing | lichenification |
| linear cleavage or cracks in the skin | fissure |
| loss of part of the epidermis; heals without scarring | erosion |
| connective tissue repair after dermal injury | scar |
| superficial punctate and linear loss of epidermis from scratching | excoriation |
| color due to melanin deposition | pigmentation |
| decrease in amount of cells in the epidermis and/or dermis with resultant thinning | atrophy |
| ring shaped, implies area of central clearing | annular |
| circular or round | circinate |
| disc-shaped | discoid |
| snake like | serpiginous |
| bull's eye-like | targetoid |
| confluent/coalescing | lesions run together |

| generalized | widespread eruption |
| grouped | lesions cluster together |
| grouped vesicles, particularly in case of herpes infections | herpetiform |
| lesions in lines | linear |
| entire skin affected | universal |
| linear arrangement along a nerve/dermatome | zosteriform |
| implies redness from vascular dilation | erythematous |
| decreased pigmentation | hypopigmented |
| increased pigmentation, of brown in color | hyperpigmented |
| violaceous | purple |
| melanotic | black |
| painful, fluctuant soft-tissue swelling | abcess |
| sack that contains a semisolid substance or fluid | cyst |
