Skin Cancer and Other Skin Problems
Lesion distribution terminology
- Annular – Circular, begins in center and spreads to periphery (e.g., tinea corporis [ringworm])
- Asymmetric – Unilateral distribution
- Confluent – Merging together (e.g., urticaria [hives])
- Discrete – Distinct individual lesions that remain separate (e.g., acne)
- Gyrate – Twisted, coiled spiral, snakelike
- Grouped – Clusters of lesions (e.g., vesicles of contact dermatitis)
- Localized – Limited areas of involvement that are clearly defined (confined to one area)
- Polycyclic – Annular lesions grow together (e.g., psoriasis)
- Solitary – Single lesion
- Symmetric – Bilateral distribution
- Zosteriform – Linear arrangement along a dermatome area (e.g., herpes zoster)
Assessment variation in light and dark-skinned person
Condition |
Light skin |
Dark skin |
Cyanosis |
Grayish blue tone, especially in nail beds, earlobes, lips, mucous membranes, palms, and soles |
Ashen or gray color most easily seen in the conjunctiva of the eye, mucous membranes, and nail beds |
Ecchymosis |
Dark red, purple, yellow, or green color, depending on age of bruise |
Purple to brownish black. Difficult to see unless occurring in an area of light pigmentation |
Erythema |
Reddish tone, possibly accompanied by increased skin temperature secondary to localized inflammation |
Deeper brown or purple skin tone with evidence of increased skin temperature secondary to inflammation |
Jaundice |
Yellowish color of skin, sclera, fingernails, palms, and oral mucosa |
Yellowish green color most obviously seen in sclera of eye (do not confuse with yellow eye pigmentation, which may be evident in dark-skinned patients), palms, and soles |
Pallor |
Pale skin color that may appear white or ashen; also evident on lips, nail beds, and mucous membranes |
Lack of underlying red tone in brown or black skin. In light-skinned African Americans, yellowish brown skin. In dark-skinned African Americans, ashen or gray skin |
Petechiae |
Lesions appearing as small, reddish purple pinpoints, best observed on abdomen and buttocks |
Difficult to see. May be evident in the buccal mucosa of the mouth or conjunctiva of the eye |
Rash |
May be visualized and felt with light palpation |
Not easily visualized, but may be felt with light palpation |
Scar |
Generally heals, showing narrow scar line |
Higher incidence of keloid development, resulting in a thickened, raised scar |
