A blog about dermatology and its related topics. Guide to cope up with dermatology disorders and some dermatology treatments.
Diagnostic Hallmarks
Distribution: random but with some predilection for sun-exposed skin
Size: 3 to 7 mm
Round and evenly pigmented
Long history of unchanged appearance
Clinical Presentation
Nevi are pigmented lesions that may be flat (junctional) or elevated (compound and intradermal). They generally vary in color from light brown to dark black, but some intradermal nevi in older adults are so […]
Diagnostic Hallmarks
Distribution: back and chest
Color variation within and among the nevi
Red hues
Irregular configuration
Clinical Presentation
The subject of dysplastic nevi ( Clark ’s nevus) is probably the most controversial one in dermatology today. Although it is certainly possible to recognize a type of pigmented lesion that is clinically atypical, the histologic presence of a typicality is […]
Malignant melanoma occurs in several distinct clinical settings. In each of these settings the melanoma has a different clinical appearance, histologic pattern, and prognosis. These various types of melanoma are grouped together because they share common color changes, a common cell of origin, and the important biologic trait of progressive, inexorable growth and eventual metastasis.
Diagnostic […]
When more than a single lesion is present, the examiner should first search for, and then focus on, the most representative lesion that can be identified. The following information regarding that lesion should be documented:
Lesion type: Some authorities divide these lesions into primary and secondary types
Color: Skin-colored, white, brown-black, yellow, or red
Margination: sharp or diffuse
Configuration: […]
Are the Lesions Solid or Fluid Filled?
In simple terms, are blisters present or not? Recognition of large, intact blisters is easy, but identification of fluid-filled lesions is problematic in two other situations. First, very small vesicles, such as those occurring on the palms and soles in dyshidrosis, are often misidentified because of the their pinhead […]
Group Identification
Lesions assigned to the brown, blue, and black lesion group must be darker than the surrounding, normal skin. Colors appropriately considered for the lesions in this group include tan, brown, black, and blue. When the lesions are brown, particularly in a dark-skinned person, a careful search for underlying red hues should be undertaken. If […]
Diagnosis Hallmarks
Disttibution - chest, back, and face
Square shouldered, sharp margination
“Stuck on” appearance
Clinical Presentation
Seborrheic keratoses are flat-topped, brown papules 5 to 20mm in diameter. They are sharply marginated and squareshouldered in cross section. They are always wider than they are tall, and their superficial, exophytic growth pattern gives them a “stuck on” appearance. Early, […]
Diagnostic Hallmarks
Distribution- generalized, sclerae involved
Skin is normal in texture on palpation
Clinical Presentation
File earliest stage of jaundice is often hard to recognize because the normal skin color masks the yellow hue. There is not a exact correlation between bilirubin levels and the degree of jaundice. However, bilirubin levels generally need to be above 2.5 mg/100 ml […]
