In specialized professions like dermatology, where terminology can be exceedingly complex and sophisticated, medical transcription is essential for the reliable documentation of patient information. Dermatology covers a broad spectrum of illnesses, skin disorders, and treatments and accurate record-keeping is necessary. Medical transcribers must guarantee precision and understanding in each transcript. Healthcare professionals that require accurate records without the hassle of manual documentation can rely on dermatology transcription services.
Understanding Dermatology Terminology
As a medical specialty, dermatology includes a wide range of words and diagnoses that call for a thorough understanding of the disorders and anatomy of the skin. Medical transcriptionists need to be knowledgeable in a wide range of medical terms, from psoriasis and dermatitis to biopsies and cryosurgery. Inaccuracies in transcription carry the risk of affecting patient care if these terms are not understood.
Transcriptionists receive specialized training in dermatology-related medical terminology. They gain knowledge of the various skin layers, kinds of lesions, and standard practices in this specialty. Accurate transcription of physician’s notes can be facilitated by their familiarity with words such as lesions, leukoderma, erythema and so on.
Here are some of the major terms used in Dermatology.
Skin structure
The deep subcutaneous tissue, middle dermis, and outer epidermis are the three layers that make up the skin. The basement membrane functions as a communication route between the two layers and divides the epidermis from the dermis.
Epidermis
The keratinocytes, or cells that make up the epidermis, are complex “brick walls” that generate the keratin protein. Also, the epidermis contains Merkel cells, which have a sensory role, Langerhans cells, which convey antigens to the immune system, and pigment cells termed melanocytes, which create melanin.
- Basal Layer– The columnar or rectangular cells at the base of the epidermis’ basal layer are the source of newly formed cells constantly. Melanocytes are often dispersed across this layer.
- Squamous cells– These are the flat epithelial cells that cover the surface of the skin. Since the skin’s cells are arranged in layers, the structure is referred to as stratified squamous epithelium.
- Granular layer– These cells that have been flattened are packed with keratohyaline protein-containing dark granules.
- The horny layer– This is the dry or keratinized stratum corneum, which is composed of stacks of dead cells devoid of nuclei. The outermost layer of cells relaxes and separates.
- Desmosomes– These are the structures that firmly connect neighboring keratinocytes to one another.
Dermis
This is the connective tissue that makes up the dermis and supports, nourishes, and shields the epidermis. The top layer below the epidermis is called the papillary dermis, and the bottom layer is called the reticular dermis.
- Collagen– The majority of the structural protein that makes up the dermis is collagen. Fibroblasts are the ones who make it. It is made up of three strong fibers twisted into a helix.
- Ground substance – The gel component of the dermis. Hyaluronic acid, dermatan sulphate, and chondroitin-6-sulphate, also known as glycosaminoglycans or anionic polysaccharides, are present in it.
- Elastin – The protein called elastin is what creates thin, elastic fibers. It is the fibroblasts that create them. They restore the resting position of distorted skin.
- Fibroblasts– These are dermal cells that produce fibronectin, elastin, collagen, and ground substance (a glycoprotein).
- Nerves– Sensory and autonomic fibers with unique nerve ends for touch, pressure, heat, cold, and pain.
- Blood vessels– Blood vessels that transport blood to and from the skin include arteries, arterioles, capillaries, venules, and veins.
- Lymphatics– The skin is nourished and drained by the vast network of thin-walled tubes known as the lymphatics.
- Arrector pili muscles– The muscles known as the arrector pili are connected to the hair follicles. Goosebumps arise from contraction.
- Cellular infiltration– Immune cells that surround the arteries and are used in large quantities to treat wounds and resist infections. Certain patterns of these cells are characteristic of several skin disorders.
Subcutaneous tissue
Adipocytes, or fat cells, make up the subcutaneous tissue, also known as subcutis. Nerves, blood vessels, and connective tissue surround them.
Distribution
The way the skin lesions are dispersed or stretched out is referred to as distribution. Skin lesions can be many or isolated (solitary or single). Given that skin disorders typically have distinct geographic distributions, the identification of numerous lesions in one area aids in diagnosis.
- Acral– Relating to or affecting the distal extremities, such as the nose, penis, nipples, ears, fingers, and toes.
- Blaschko lines– These are a pattern of lines on the skin representing the developmental growth pattern during epidermal cell migration.
- Dermatomal– These are lesions that are restricted to one or more skin segments that are innervated by a single spinal nerve.
- Extensor– Involves the limbs’ extensor surfaces, as opposed to flexor surfaces.
- Flexural– Flexural refers to skin folds that are associated with flexion, as those found in the groin, armpits, backs of knees, and elbow creases.
- Follicular– Lesion inside or surrounding hair follicles is known as a follicular lesion.
- Generalized– Lesions that are classified as “generalized” are spread randomly throughout the majority of the body’s surface area or within a specific anatomical region.
- Herpetiform– A cluster of firm papules.
- Koebnerized– Koebnerized refers to the development of new skin disease lesions, like psoriasis, near the trauma site.
- Photosensitive– Photosensitivity is an increase in the skin’s sensitivity to sunlight.
Configuration of lesions
The term “configure” describes the outline or form of the skin lesions. Skin lesions tend to cluster together. Given that many skin disorders have a distinctive configuration, the pattern or form may aid in the diagnosis.
- Nummular lesions: Also called discoid lesions, these are round, coin-shaped lesions.
- Linear lesions: Often called striates, they have a linear shape and are frequently caused by external factors like scratching.
- Target lesion: Iris lesions are also called target lesions; they resemble concentric circles on a dartboard.
- Gyrate rash: A rash that has a circular appearance.
- Annular: Lesions in a circle are called annular lesions.
Color
The following descriptive words are used to characterize skin color:
- Carotenoderma: It is a yellow-orange skin tone that is caused by an overabundance of beta-carotene, a vitamin precursor that is found in yellow-orange fruits and vegetables. It primarily affects the palms and soles and spares the sclera.
- Hyperpigmentation: Darker skin than usual, can be either localized or widespread.
- Hypopigmentation: It refers to skin tone that is lower than usual.
- White skin, or leukoderma, also called achromia.
- Black patches of necrotic tissue caused by a cut-off blood supply are called infarcts.
- Jaundice: An excess of bile pigments in the blood causes jaundice, which is yellowing of the skin and the whites of the eyes. Liver or biliary diseases are typically the cause of jaundice.
- Erythema: Red skin from an increased blood supply, can be used to describe any dermatosis with a red color.
Surface of the Skin
A skin lesion’s surface may appear smooth or normal because of the pathological process—which could be dermal or subcutaneous-that occurs beneath it. Surface changes suggest the presence of epidermal alterations.
- Scaling, also known as hyperkeratosis, is an increase in dead skin cells on the stratum corneum, the skin’s outer layer. Among the descriptive terms for scale are:
- Desquamation, or the peeling away of scales
- Psoriasiform (with big silver or white flakes)
- Pityriasiform, or powdery branny scale
- Lichenoid (skin surface appears to be closely adhering to scale)
- Keratotic (scale with horns)
- Exfoliation (skin peeling)
- Maceration (the peeling of moist skin)
- Warty and verrucous.
Secondary changes
- Lichenification– Chronic rubbing can lead to lichenification, which is characterized by palpably thicker skin, more skin marks, and lichenoid scaling. It happens in lichen simplex and persistent atopic eczema.
- Crusting– It is the outcome of plasma seeping through the skin’s erosion. It is either brown or yellow in color, and its surface is rough. Bloody crust can be purple, black, or crimson in color.
- Dystrophy– It is the abnormal formation or deterioration of the skin. It’s frequently used in reference to nail conditions.
- Excoriation– It is the result of scratching or an external injury that causes the epidermis and a piece of the dermis to shed. It could be punctate or linear.
- Erosion– A sore caused by the partial or superficial breakdown of skin or other surface tissue.
- Fissure– It is a thin skin ulceration, split, fracture, or erosion.
- Fungating– A big malignant tumor that is proliferating like a mushroom or fungus is described as “fungating.”
