Study Notes

Unit 7: Integumentary Disorders

Terminal Learning Objectives

  • Determine what exams and questions to ask to accurately identify the correct treatment plans for integumentary disorders

Enabling Learning Objectives

  • Analyze facts and principles related to integumentary disorders
  • Distinguish signs/symptoms/findings of common and life-threatening integumentary disorders
  • Comprehend importance of patient interviewing to arrive at correct diagnosis
  • Differentiate integumentary disorders
  • Calculate treatment plans and patient education for integumentary disorders
  • Appropriately identify red flags

Unit Overview

  • Conditions discussed include: Fungal Infections, Intertrigo, Pityriasis Rosea, Acne Vulgaris, Rosacea, Impetigo, Erysipelas, Cellulitis, Furunculosis Folliculitis, and Pseudofolliculitis barbae (PFB)
  • Also covers: Warts, Molluscum Contagiosum, Scabies, Pediculosis, Epidermal Inclusion Cyst, Actinic Keratosis, Squamous Cell Carcinoma, Basal Cell Carcinoma, and Malignant Melanoma

Important Integumentary Note

  • Note, most diagnoses lack a description or pictorial representation of the various disorders for people of color
  • Conduct a thorough and careful history and examination as presentations vary with all skin tones
  • Skin exams will sensitive patient areas, be respectful

Skin Structure

  • The skin has two layers called the Dermis and Epidermis
  • The Epidermis has 5 cell layers and 3 cell types
  • Keratinocytes provide strength and waterproofing
  • Melanocytes provide pigment of epidermis and absorb/scatter UV radiation
  • Langerhan's cells are macrophages
  • The epidermis lacks blood vessels

Dermis Characteristics

  • Functionally comprises fibrous connective tissues with nervous tissue and blood supply
  • Hair follicles, nails, skin glands (eccrine & apocrine sweat glands), sensory receptors, blood vessels and smooth muscle fibers originate in the dermis

Subcutaneous Layer Traits

  • Connects the skin to underlying organs
  • Contains major blood vessels that supply skin
  • There is no sharp boundary between it and dermis
  • Insulates for thermoregulation which conserves body heat and keeps heat out

Skin Lesion Terminology

  • Macule: Usually <1cm
  • Patch: Usually >1cm
  • Scale
  • Papule
  • Plaque
  • Nodule
  • Pustule
  • Vesicle
  • Bulla
  • Wheal
  • Crust
  • Erosion
  • Fissure
  • Ulcer
  • Hypertrophic Scar
  • Keloid
  • Excoriation
  • Lichenification
  • Cyst
  • Milia
  • Comedones
  • Petechia
  • Purpura
  • Telangiectasia

Calluses and Corns

  • Areas of hyperkeratosis occur at a site with high intermittent pressure or friction
  • Calluses are generally superficial, often covering broad areas of skin lacking a central plug
  • Corns are deeper lesions frequently painful or tender when pressure is applied

Signs and Symptoms for Calluses and Corns

  • Thick superficial lesions are more likely calluses; extreme friction makes calluses become thick and irritated
  • Deeper skin lesions are more likely corns, frequently painful and tender when pressure is applied

Focused History for Calluses and Corns

  • Inquire about shoe type
  • Check for poorly fitting military boots
  • Assess activity level and note any recent changes

Physical Exam for Calluses and Corns

  • Calluses lack a central plug and have a more even appearance
  • After paring, calluses show smooth translucent skin
  • Corns feature a keratinous plug, pea-sized or slightly larger, that extends through most of dermis
  • Soft Corns: Form between toes
  • Hard Corns: Over prominent bony protuberances
  • Paring shows a sharply outlined yellowish to tan translucent core

Differential Diagnosis for Calluses and Corns

  • Bunion: valgus deformity of great toe
  • Metatarsalgia: pain on the plantar surface of 2nd and 3rd metatarsals
  • Plantar wart: verrucous papule that may have pain with pressure
  • Molluscum contagiosum: pearly umbilicated papules
  • Furuncle: painful inflammatory swelling

Treatment for Calluses and Corns

  • Clinic: Manual removal (paring) using a dermablade or scalpel to gradually shave off layers of hyperkeratotic tissue
  • Home: Nail file, emery board, or pumice stone immediately after bathing to remove keratotic tissue
  • Use of keratolytics like salicyclic acid
  • Cushioning and altering foot biomechanics can help prevent corns and help existing corns
  • Reduce the pressure of the affected surface by redistributing where possible, use pads rings, and moleskin to help
  • Wear soft, well-fitting shoes where toes can move freely

Calluses and Corns: Follow Up Actions

  • Return for further evaluation if symptoms do not improve within 1 month
  • Green Directive: Routine Review by Preceptor IAW 44-103

Subungual Hematoma

  • Occurs when blood becomes trapped between the nail plate and the nail bed

Subungual Hematoma: Signs and Symptoms

  • Pain results from pressure in a confined space
  • Possible eventual separation of and temporary loss of the nail plate

Subungual Hematoma: Focused History

  • Trauma or injury history will provide vital information

Subungual Hematoma: Physical Exam

  • Look for swelling, ecchymosis, and disruption of nail plate
  • Blood may be visible under nail and the nail may be tender to palpation

Subungual Hematoma: Differential Diagnosis

  • Fracture if trauma is suspected, x-ray is needed
  • Subungual melanoma shows a pigmented nail, is painless, nail grows and spot doesn't move and no trauma history
  • Subungual keratoacanthoma presents suddenly with pain, swelling, and inflammation without trauma history

Subungual Hematoma: Treatment

  • Nail trephination can be used within 24-48 hours
  • Create a hole in nail plate to permit blood escape with an 18-gauge needle in a rotary, drilling motion/electrocautery device
  • Do not perform if nail is injured or deformed
  • Video reference to watch is https://www.youtube.com/watch?v=o7zB0uHT_lc

Subungual Hematoma: Follow-up Actions

  • Follow up for further evaluation if symptoms do not improve within 1-2 days
  • Green Directive: Routine Review by Preceptor IAW 44-103

Ingrown Toenail

  • Incurvation or impingement of a nail border into it's adjacent nail fold causes severe pain
  • Causes can be excessive trimming of nail plate tight shoes, abnormal gait, bulbous toe shape or various congenital variations in nail countour
  • Infection can eventually occur along the nail margin referred to as paronychia

Ingrown Toenail: Signs and Symptoms

  • Pain can be felt along corner of the nail fold or less commonly the entire lateral margin.
  • Discomfort initially is mild (especially with offending shows) but will increase over time

Ingrown Toenail: Focused History

  • Note any shoes worn (ex: military boots)
  • Activity Level
  • History of nail trauma
  • Nail trimming, either too short or rounded edges is a common cause

Ingrown Toenail: Physical Exam

  • Assessment presents clear incurvation or impingement of a nail border into the adjacent nail fold

Ingrown Toenail: Differential Diagnosis

  • Osteochondroma: Benign bone tumor common in young adults, X-rays are needed
  • Paronychia: Infection of the periungual tissues that causes pain along the nail margin
  • Amelanotic melanoma: occurs in older adults, granulation tissue surrounds toe
  • Tinea unguium (onychomycosis): presents as lusterless, brittle, discolored, hypertrophic nails
  • Bunion presents with valgus deformity of great toe

Ingrown Toenail: Treatment

  • In mild cases, insert cotton between ingrown nail plate and painful fold using a thin instrument
  • In more moderate development of infection, nail partial or occasionally total nail excision occurs
  • For recurrent ingrown nails, consider destruction of adjacent nail matrix with phenol or trichloro-acetic acid, ask for preceptor guidance if you chose a permanent solution

Ingrown Toenail: Follow-Up Actions

  • Wear well-fitting shoes, a larger toe box may help!
  • Warm Epsom salt soaks may relieve some symptoms
  • Proper nail trimming, cut straight across
  • Change socks often if in the field environment
  • Return for further evaluation if symptoms do not improve in one week or sooner if symptoms worsen
  • Green Directive: Routine Review by Preceptor IAW 44-103

Paronychia: Cause and Onset

  • Infection of tissues surrounding nail margin
  • Causative organisms: Staphylococcus aureus or streptococci
  • Organisms most often enter through a epidermal break causing inflammation, hangnail, trauma on the nail fold, loss of cuticle/ chronic irritation
  • In toes, infection starts as an ingrown toenail

Paronychia: Signs and Symptoms

  • Symptoms appear across margin of redness, swelling warmth and swelling
  • Discharge usually develops across nail margin/sometimes beneath

Paronychia: Physical Exam

  • Note, redness, swelling pain
  • Possible discharge / pus
  • Nail borders tender to palpation
  • Gait abnormalities

Paronychia: Differential Diagnosis

  • Felon: painful swollen pad of digit (“fingertip”), and often requires incision/drainage procedures
  • Osteochondroma: benign bone tumor common in young adults, X-rays needed
  • Amelanotic melanoma: occurs in older adults, granulation tissue is often seen surrounding toe
  • Ingrown toenail: incurvation or impingement of nail border into adjacent nail fold
  • Bunion: presents with valgus deformity of great toe

Paronychia: Treatment - Antibiotics, Drainage, and Potential for Infected Ingrown Toenail

  • Antibiotics will often consist of dicloxacillin or cephalexin, some CA-MRSA (community acquired methicillin resistant S. Aureus) cases will call for use of trimethoprimsulfamethoxazole or doxycycline
  • If the case has a fluctuant swelling or visible pus, drain with using with a #11 scalpel blade inserted between nail and nail fold. Skin incision is unnecessary
  • For an infected ingrown toenail, nail excision is used

Paronychia: Follow-Up & Preventative Actions

  • Warm compress and Epsom salt will likely help, initially.
  • Return for further reevaluation of symptoms don't improve in 1 week or sooner, symptoms worsen
  • Green Directive: Routine Review by Preceptor IAW 44-103

Urticaria

  • Consists of migratory, well-circumscribed, erythematous, pruritic plaques on the skin
  • Results from stimuli on an immunologic or nonimmunologic basis
  • The most common immunologic mechanism is mediated by IgE
  • Nonimmune-mediated mast cell activation by certain drugs, physical or emotional stimuli- mechanism is poorly understood
  • Most incidents are acute and self-limited (1-2 weeks)
  • Acute urticaria is often the result of food ingestion, infection, insect bite or sting, or medications.

Urticaria: Chronic vs Angioedema

  • Chronic urticaria lasts more than 6 weeks, often autoimmune or idiopathic in orgin
  • Angioedema may accompany urticaria
  • Angioedema is the involvement of deeper subcutaneous tissue with swelling of the lips, eyelids, palms, soles, and genitalia.
  • If the patient with angioedema involving lips, tongue, and mouth, immediately assess for signs of airway compromise

Urticaria & Angioedema: Signs & Symptoms

  • Well demarcated
  • Transient
  • Often involving the dermis
  • Red
  • Varies in size
  • Intensly pruritic
  • Lasts <24hrs
    • often only 2-4 hours

Urticaria & Angioedema: Focused History

  • Exposure history is key
    • Assess use of medications, food, and infections

Urticaria & Angioedema: Physcial Exam

  • Swellings range from millimeters to centemeters
  • The morphology of the lesion may vary over time, often resulting in bizarre or geographic patterns
  • Dermatographism may also be present
  • Wheal may appear after even small amounts of pressure to the skin
    • ie; scratching the skin

Urticaria: Differential Diagnosis

  • Papular urticaria is often correlated with insect bites, with it's central component
  • Those with hereditary angioedema have an extremely positive family history of gi or respiratory problems
  • Urticarial vasculitis often presents as serum sickness or an extreme drug reaction
  • Diffuse, symmetric, drug eruptions is associated with exposure to antibiotics such as anticonvulsants
  • Cellulitis is a diffuse, spreading infection from dermis w/ subcutaneous tissue, w a smaller/localized area

Urticaria Treatment & Follow-up

  • First generation antihistamines like hydroxyzine or diphenhydramine can be effective
  • Second generation antihistamines should be used 1st line and be less sedating

H2-blockers as Adjunct Therapy

  • H2 blockers like cimetidine can be utilized, systemetic corticosteroids are used in diffused areas with severe symptoms/with preceptor approval
  • To note corticosteroids are not chronic urticaria
  • Avoid all inciting factors such as hot air, food, stress, and drugs
  • Track all episodes with a episode diary, for those with unknown factors
  • Consistently maintain airway patency with frequent monitoring
  • Return for further evaluation if no airway has been compromised in 1 day
  • Blue Directive: Contact Preceptor Immediately

Drug Eruptions

  • Presents as cutaneous drug reactions, typically have acute abrupt onset due to symmetric widespread erythematous reactions
  • Rashes are most adversive and frequently are caused by antibiotics and other anti-convulsants
  • Often caused by - Amoxicillin - Ampicillin - TMP-SMX

Drug Eruption: Intensity Factor

  • Intensity ranges from little pigment changes to an exfoliative dermatitis or even toxic epidermal nercrolysis, which causes hospitilization and extensive blistering that has a great affect on the membranes

Drug Eruptions: Signs and Symptoms

  • Simple drug eruption:
    • Often attributed from antibiotics
    • Has a component of diffuse exanthem (rash) with little constitutional symptoms
    • Complex drug eruption, often attributed from - sulfonamides - Allopurinol/anticonvulsants -Has a feverish constitutional that can present as a Arthralgia or malaise

Drug Eruptions: Physical Exam, Diagnosis,

  • Assess any morbiliform or exanthematous that displays an exfloliative dermatitis
  • Determine if there is angioedema and any vasculitis symptoms
  • Be aware of Stevens-Johnson syndrome, which will require quick treatment, as the symptoms can be life threathening
  • Key to diagnosis, check medication hystory prescription & OTC
  • After any discontinuation, evaluate any additional issues, this helps to make sure that what's helping is working
  • Rechallenge could cause danger so it may need to be avoided if other options are exhausted

Drug Eruptions: Differential Diagnoses

  • Check for Angioedema and Urticaria that has diffused into a skin lesion with pruritic reactions
  • In drug eruptions there may be papillae, which needs to be investigated
  • Once a diagnosis is determined, stop offending agent

Drug Eruptions: Medication & Follow-up

  • Anti-histamines can help with uritcarial effects
  • Severe reactions can be stopped with EVAC and immediate transfer for treatment
  • Add any past allergies to the patient allergy logs with the proper reactions
  • Blue Directive: Contact Preceptor Immediately and monitor those symptoms, evaluate is symptoms persist after 48 hours or sooner

Contact Dermatitis

  • Acute or chronic dermatitis from direct skin contact with irritants or allergens
  • Types include Irritant Contact Dermatitis and Allergic Contact Dermatitis
  • ICD is caused by non-immune-modulated irritation of the skin by a substance leading to skin changes
  • ACD is a delayed hypersensitivity reaction in which a foreign substance comes into contact with the skin; skin changes occur with reexposure
  • 80% of occupational contact dermatitis; highest among those with "wet work" exposures - food handlers, health care workers etc.
  • Most common causes are poison /oak, topical antimicrobials, anesthetics, hair care products, jewelry (nickel), rubber, essential oils

Contact Dermatits: Signs and Sympthoms

  • Irratant Contact Dermatitis: - Acute is more painful than pruritic - Possible erythema, scaling & edema to erosions, crusting+blistering - Chronic is more often pruritic
  • Allergic Contact Dermatitis: - Pruritic rather then painful - Possible erythema, scaling & edema through vesiculation to severe swelling with billie
  • Localisation: Suggest the cause, hair dyes, or shampoo for scalpe + Face creams, cosmetics for face wash

Contact Dermatitus: Focused History & Physical

  • Occupational exposures, outdoor activities, or new body/hare products can help reveal cause
  • Also asess household duties, cosmetics habits + clothing choices
  • Physical:
    • Inspect if the skin is scaling, eruthmia, fissuring of scaling or crusting of the lesion
    • A linear streak pattern of the skin, suggest & allergic irratation cause by a type of plant
