Describing Skin Lesions (Dermatological Nomenclature) - Macule, Papule, Pustule, Vesicle & Others

A macule, is a flat lesion that is usually circumscribed, and non-palpable, because it is not elevated above the skin surface. A papule, is also a circumscribed lesion, but it is palpable. They are smaller in size, typically less than 0.5-centimiters in diameter. A plaque, is a larger, palpable lesion. Its top is flat, and it is raised above the skin surface. A pustule, is a yellow-white pus-filled lesion, which is raised above the skin surface, hence palpable. They commonly occur due to infection. However, there are non-infective causes as well. A vesicle, is a small, fluid-filled blister, typically seen in impetigo and various bacterial infections. A bulla, is a larger, fluid-filled blister, measuring more than 1-centimeter in diameter. They commonly occur in bullous impetigo and bullous pemphigoid. Crusting, is caused by dried serum or exudate, typically after rupture of vesicles or bullae. Petechiae, are pinhead sized, non-blanching areas of hemorrhage. Purpura, is a large macule or papule of blood in the skin, which does not blanch on pressure. Ecchymosis, is a large confluent area of purpura. In Lichenification, epidermis become thicker with normal prominent skin markings. Finally, and excoriation is a superficial skin abrasion, which is usually due to scratching. #dermatology #medtoday skin lesions,dermatology for medical students,dermatology for health care,lesion (symptom),skin lesions nursing,types of skin lesions,dermatology lesions,dermatology nomenclature
