Nikolsky's sign ?

Types of Nikolsky’s sign ?
May 1, 2023 35
Types of Nikolsky’s sign Direct Nikolsky’s sign-
When sign is elicited in normal skin away from the blister Indicates severe disease activity.
Marginal Nikolsky’s sign- When sign is elicited in normal skin near blister.
Pseudo Nikolsky’s sign- Shearing or tangential force cause peeling of skin which
is due to necrosis of the cells in contrast to acantholysis in pemphigus. Seen in Stevens-Johnson syndrome, Toxic epidermal necrolysis, burns.
May 1, 2023 36
Types of Nikolsky’s sign cont….. Microscopic Nikolsky’s sign-
Sign is elicited by rubbing normal appearing skin with an eraser around the blister to cause a microscopic blister.
Useful for taking a biopsy for histopathology.
False Nikolsky’s sign- This involves pulling of the peripheral remnants of
ruptured blister, thereby extending the erosion on the surrounding skin. Sign is positive in sub epidermal blistering disorders such bullous pemphigoid, JEB, mucous membrane pemphigoid.

Tzanck cells in pemphigus vulgaris (Giemsa stain, 40X )
Rounded keratinocyte with: perinuclear halo Hypertrophic/ dysmorphic
nucleus hazy or absent nucleoli increased N:C ratio abundant eosinophilic to
basophilic cytoplasm
May 1, 2023 40
Tzanck Smear ?
May 1, 2023 41
Tzanck Smear It is a bedside procedure done in blistering
disorders
The roof of the intact blister is opened along one side and floor is gently scraped with blunt edge of blade and material obtained is smeared on a glass slide and allowed to air dry.
Stained with Giemsa stain
May 1, 2023 42
Tzanck smear in cytodiagnosis ?
May 1, 2023 43
Skin biopsy
Epidermis : Suprabasal split with group of
acantholytic cells in the split. Basal layer shows loss of
adhesion with adjacent keratinoctye but attached to the basement membrane giving appearance of “row of tombstones”
Dermis: Superficial dermis shows scanty
perivascular lymphocytic infiltrate.

Summary?
May 1, 2023 47
Summary
32 years serving solider , hailing from Maharashtra, married with no co-morbidities with h/o non healing ulcers in mouth and fluid filled skin lesions/erosions over upper body with little tendency to heal for the last five months.
Dermatological examination revealed multiple raw area over scalp , face, neck, chest and back.
Tzanck smear, Skin biopsy, IF studies s/o Pemphigus Vulgaris

Diagnosis
Pemphigus Vulgaris
May 1, 2023 49
Pemphigus ?
May 1, 2023 50
Pemphigus
Autoimmune blistering disease characterized by blisters and erosions on the skin or mucosal membranes or both
Characterized by intraepidermal split
May 1, 2023 51
Classification Pemphigus vulgaris
- Pemphigus vegetans • Pemphigus vegetans of Neumann • Pemphigus vegetans of Hallopeau
Pemphigus foliaceus - Pemphigus erythematosus - Endemic pemphigus
Paraneoplastic pemphigus Drug induced pemphigusIgA pemphigus
- Subcorneal pustular dermatosis - Intraepidermal neutrophilic IgA dermatosis
May 1, 2023 52
Epidemiology Prevalence 0.09% to 6.8% ( India 0.09 to 1.8 %)
Both sex equally affected
Average age fourth and fifth decades( third and fourth in India)
Pemphigus vulgaris is commonest type
Most common in North India, Gujarat, Maharashtra and Assam
May 1, 2023 53
Etiology Genetic Determinants
Pemphigus vulgaris is linked to HLA DRB1 *0402, HLA DQB1*0503.
Environmental Factors Exposure to ultraviolet light Pesticides and foods (nuts, mangoes, bananas, tomatoes,
garlic, onion) having thiol, phenols, polyphenolic compound, drugs
Immunological Factors Autoimmune disease and autoantibodies against antigens
located in the epidermis ○ Desmogleins (Dsg-1, Dsg-3)○ Acetylcholine receptors (AChR alfa 9)○ Pemphexin
Pathogenesis
Antibodies to epidermal Desmoglein 1&3 (cell-cell adhesion molecule)
Immune complexes deposited b/w keratinocytes - intraepidermal clefting
Acantholytic cells
‘Row of tombstones’ Fishnet pattern on DIF
May 1, 2023 55
Clinical features Oral ulcers- 50-70% patient present with oral
lesions only Painful Little tendency to heal
Skin blisters- Flaccid on normal appearing skin Easily rupture its own Usually painless without itching Little tendency to heal Characteristic musty offensive odour Head, face, neck, upper trunk, axilla, groin and pressure
points are common area involved
May 1, 2023 56
Course and prognosis Average mortality without treatment is about 100% in severe
disease
With the use of steroids mortality is about 23%
With early diagnosis, use of steroids, immunosuppressants and improved treatment of complications mortality is about 5 – 15%
Most common cause of deaths Septicemia Pulmonary embolism Complication of steroids and immunosuppressants
May 1, 2023 57
Management Aim of treatment :
Decrease blister formation
Promote healing of blisters and erosions
Determine minimal dose of medication necessary to control the disease process
May 1, 2023 58
Contd…..
Therapy must be tailored for each patient, taking into account severity, preexisting and coexisting conditions
Evaluation by Physician For any comorbidities
Evaluation by Ophthalmologist Those patients requiring prolonged high-dose steroids for ocular
involvement i.e Intraocular pressure, cataract.
Evaluation by a Rheumatologist Patients requiring long term systemic corticosteroids/ ‘mabs
May 1, 2023 59
Contd…
Adequate nutrition Nursing care Control of secondary infections Fluid and electrolyte monitoring
May 1, 2023 60
Treatment Topical (mild cases)
Topical potent steroid Topical tacrolimus Topical epidermal growth factor(EGF)
Intralesional steroids (to hasten remission) Triamcinolone acetonide (5-10mg/ml for mucosal) (10-20mg/ml for cutaneous
lesions) every weekly
Systemic steroids: Mainstay of treatment Daily dosing Pulse therapy
Oral steroids + Immunosuppressants Cyclophosphamide, Azathioprine, Cyclosporine, Mycophenolate mofetil,
Methotrexate Dexamethasone cyclophosphamide pulse
May 1, 2023 61
BiologicsRituximab with or without Immunosuppressants
IVIG
Plasmapheresis
Immunoadsorption
Extracorporeal photochemotherapy
Definitive Management – this patient
• Monthly Dexamethasone Cyclophosphamide Pulse
• Interval Prednisolone 15mg daily
• Interval oral Cyclophosphamide 50mg daily
Five cycles of DCP given with moderate control of blisters
62May 1, 2023
May 1, 2023 63
Management (contd)….. In view of:
Moderate control of the disease Long course of DCP therapy Long term side effect of systemic steroids Sports career of the patient Family not complete
Patient given Rituximab after thorough work up
RA protocol- Two does o f 1gm 15 days apart, slow IV infusion.
1st dose given and patient tolerated therapy well
Oral Cyclophosphamide 50mg daily continuing
In remission without daily steroids
