  1. CUTANEOUS LUPUS ERYTHEMATOUS Tayyaba Mumtaz PG#2
  2. What Is Systemic Lupus Erythematosus? • Systemic lupus erythematosus (SLE) is a progressive chronic autoimmune disease that results in inflammation and tissue damage • Characterized by flares, spontaneous remission, and relapses • Highly heterogeneous • Can affect any part of the body – Often damages skin, joints, heart, kidneys, lungs, nervous system
  3. ACR (1997) Revised Criteria for Classification of SLE Skin Criteria • Butterfly rash • Discoid rash • Sun sensitivity • Oral ulcerations Systemic Criteria • Arthritis • Serositis • Kidney disorder • Neurological disorder Laboratory Criteria • Blood abnormalities • Positive ANA blood test • Immunologic disorder o Antiphospholipid antibodies, lupus anticoagulant, anti-DNA, false-positive syphilis test, positive anti- Sm 4 of 11 needed for a diagnosis
  4. SLICC SLE Diagnostic Criteria (2012) Requirements:>criteria (at least 1 clinical and 1 lab criteria) OR biopsy-proven Lupus nephritis with positive ANA or Anti-DNA CLINICAL CRITERIA IMMUNOLOGIC CRITERIA ACUTE OR SUB ACUTE CUTANEOUS LUPUS ANA CHRONIC CUTANEOUS LUPUS ANTI-DNA ORAL ULCERS OR NASAL ULCERS ANTI-SM NON-SCARRING ALOPECIA ANTIPHOSPHOLIPID ANTIBODY POSITIVITY, AS DETERMINED BY POSITIVE TEST FOR LUPUS ANTICOAGULANT SYNOVITIS INVOLVING 2 OR MORE JOINTS SEROSITIS RENAL DIRECT COOMBS’ TEST (IN THE ABSENCE OF HEMOLYTIC ANEMIA NEUROLOGIC HEMOLYTIC ANEMIA LEUKOPENIA (<4000/MM3) OR LYMPHOPENIA (<1000/MM3) THROMBOCYTOPENIA (<100,000/MM3)
  5. Diagnosis • No single test can determine whether a person has lupus, but several laboratory tests may help make a diagnosis • Diagnostic Tests – Antinuclear antibody (ANA) test – Autoantibodies: anti-DNA, anti-Sm, anti-RNP, anti-Ro (SSA), and anti- La (SSB) – Anticardiolipin antibody – Antiphospholipid antibody – Skin biopsy – Kidney biopsy
  6. CUTANEOUS LUPUS ERYTHEMATOSUS • CLE is Lupus affecting the skin. • Body’s immune system attacks healthy skin. • Three main sub types are: a. Acute Cutaneous Lupus (ACLE). b. Sub Acute Cutaneous Lupus (SCLE). c. Chronic Cutaneous Lupus (CCLE).
  7. CUTANEOUS LUPUS ERYTHEMATOSUS ACLE SCLE CCLE • Acute clinical course • Sub acute clinical course • Chronic clinical course • Rapid development of Cutaneous manifestation • Development of Cutaneous manifestation Over several weeks • Development of Cutaneous manifestation Over several months • 90% associated with systemic involvement • 20-30% associated with systemic involvement • Less than 5% associated with systemic involvement
  8. Acute cutaneous lupus Erythematous • There are two Forms of ACLE i. Localize Form ii. Generalize Form
  9. LOCALIZE FORM • Malar or butterfly rash that covers cheeks and nasal bridge. • Forehead and anterior neck may included. • Nasolibial folds are spared. • Rash triggered by sunlight, last days to weeks. • Reddish purple discolourization with mild edema and or papule are common. • d/ds acne rosescea ,seborrheic dematitis, dermatomyocitis which involves nasolibial folds.
  10. GENERALIZE FORM • Less common than localized form. • Maculopapular rash, or photosensitive dermitis, above or below neck on sun exposed areas.
  11. Diagnosis • Skin biopsy • Basal layer degeneration, edema at upper dermitis, mononuclear cell infiltration at dermal-epidermal junction, hyperkeratosis and perivasular inflammation. • Direct immunoflorence • Granular deposition of immunoglobins IGM and compliments C3 at dermal- epidermal junction.
  12. Treatment • Sun protection, Smoking cessation. • Topical Steroids • Systemic • Anti-malarial (chloroquine and hydrochloroquine) • Oral steroids in severe cases.
  13. Subacute cutaneous lupus SCLE • Rash on sun exposed skin ,upper torso, back, neck and arm, mid face is usually spared. • Erythematous, annular, polycystic lesion or may have non indurated, psoriform, polysquamous appearance. • 10 to 30% drug induced • Antihypertensive, thiazide diuretics ,ACE inhibitors, PPIs and antiepileptics. • Histopathalogy interface dermitis ,hyperkeratosis, basement mem thickining, follicular plugging and lymphocyte infiltration. • Treatment : Topical steroids , oral antimalarials.
  14. Subacute cutaneous lupus SCLE
  15. Chronic cutaneous lupus CCLE • Most common is discoid lupus, • Lesion classically on face, scalp, ears can also effect lips, nasal mucosa, conjunctiva and genitilis. • Triggers sun exposure, trauma, cold exposure, infection, dermatitis, thermal burns. • Coin shaped erythematous plaque, follicular hyperkeratosis and plugging , high potential for scarring. • Treatment topical steroids, topical calcineris, antimalarials,methotrexate,sytemic retinoid, thalidomide, dapsone, azothioprine.
  16. Chronic cutaneous lupus CCLE
  17. Atypical and Rare forms of CLE • Rare form of ACLE i. Bullous lupus Erythematous • Rare form of SCLE i. Erthrodermic LE ii. Lupus Erythermatosus gyratus repens iii. EAC-like LE
  18. Atypical and Rare forms of CCLE • Rare form of CCLE i. Hypertrophic ii. Lupus comedonicus iii. Lupus mastitis iv. Monogenic LE v. TEN (Toxic Epidermal Necrolysis)-like LE vi. EEM(Erythema exsudativum multifome)-like LE
  19. Bullous lupus Erythematous • Disseminated vesicles and crusts on erythematous to clinically normal skin. • Accompanied by residual hyperpigmentation and milia.
  20. Erthrodermic LE • Rare form of subacute cutaneous lupus occurs after sun exposure. generalized exfoliative erythroderma.
  21. Lupus Erythermatosus gyratus repens • Very rare varient of SCLE,with chronic recurrent figurate erythematous annular plaques.
  22. EAC-LIKE LE • Annular erythematous plaques with trailing scale similiar to eac erythema annular centifugum.
  23. OTHER FORMS OF ACLE • TEN like LE.(Toxic Epidermal Necrolysis) • EEM like LE.(Erythematic Exsudativum ) • Very rare forms of ACLE, associated with drug reaction.
  24. Hypertrophic • Rare form of CCLE ,on face and extensor surface of limbs, sole and palms.yperkeratotic lesion with congestive margins and central atropy
  25. Lupus Comedonicus • Erythematous to brown infiltrated plaques with open comedones .
  26. LUPUS MASTITIS • Breast involvement of lupus prefundus, chronic course with remission and flares.
  27. MONOGENIC LE • Rare variant with single gene mutation, occurs in children manifest in CNS, kidney, joint and skin.
  28. LINEAR LE Rare form CCLE, in children, especially on face and limbs.
