In this article, I discuss seborrheic keratosis, stucco keratosis, benign melanocytic nevus, cutaneous horn, actinic keratosis, blue nevus, lentigo, and porokeratosis. Discover the symptoms and see pictures. Nevertheless, it is useful to know how the common skin lesions look like to be able to recognise them. c. Primary Skin Lesions. A macule (figure 3-3) is a definite area of skin in which the skin color has changed from the normal skin color. (1) Macule. Macule: a flat area of altered colour less than 1.5cm in diameter. These 2 types of skin lesions can be differentiated as follows: The majority of skin lesions are benign, but when a new lesion or mark appears on our skin, it can be difficult to tell whether it is dangerous. Secondary 3. special 4. Black skin lesions may be melanocytic, including nevi and melanoma. Black eschars are collections of dead skin that can arise from infarction, which may be caused by infection (eg, anthrax , angioinvasive fungi including Rhizopus, meningococcemia ), calciphylaxis , arterial insufficiency, or vasculitis . Benign lesions can be classified by their cellular origin: melanocytic, keratinocytic, vascular, fibrous, fat, and so on, Which are the common melanocytic lesions? Papule: a solid raised palpable lesion less than 0.5cm in diameter. Primary lesions are those lesions that arise de novo and are therefore the most characteristic of the desease process. This area is neither higher nor lower than the surrounding skin area. The skin of elderly persons possesses a greater number of benign growths and neoplasms than the skin of younger and middle-aged persons. Secondary skin lesions result from complications of primary skin lesions. Leprosy (or Hansen’s disease) is a chronic, progressive bacterial infection that can cause disfigurement and disability if left untreated. Patch: a flat area of altered colour greater than 1.5cm in diameter. From this information, diagnostic possibilities are considered. If you have any suspicions about a mark, mole or lesion, you should ask your doctor to check it. Skin lesions can be seen during a general physical examination in a dermatology clinic. When describing a skin lesion,it is important to note the following features:- 1)size 2)type 3)shape and symmetry 4)colour and pigmentation 5)surface area 6)Distribution over the body surface 3. Primary skin lesions are those which develop as a direct result of a disease process. Types of lesion Basic skin lesions are broadly categorized as : 1. Primary lesions (e.g., macules or papules) appear as a direct result of a disease process. Bulla : a circumscribed, elevated fluid-filled lesion greater than 1 cm in size (e.g. Primary 2. Common benign skin lesions of melanocytic origin include the ephilis, lentigo simplex, and melanocytic naevus (mole). Primary skin lesion s are basic and simple. A primary lesion is a change in the skin that is caused by a certain disease or infection. There are several different types, including the macule, papule, vesicle, plaque, bulla, patch, tumor, wheal, nodule, and pustule.These are not specific to one disease, and are not always considered to be a primary lesion. Skin lesions may be primary or secondary. Secondary lesions such as scales or ulcers may develop from primary lesions or result from external trauma (e.g., infections, scratching). There are two kinds of skin lesions. In contrast, secondary skin lesions result from changes over time caused by disease progression, manipulation (scratching, picking, rubbing), or treatment. This findings are recorded as morphology of lesion, the distribution of lesions and the arrangement or grouping of lesions.
