Additional workup • ENA SM AB : 1.2 pos RNP AB : 1.2 pos • Anti- ds DNA : 1149 pos DIAGNOSIS: SLE with EM= Rowell syndrome
Rowell syndrome • Original criteria for Rowell syndrome: 1- Lupus erythematosus 2- Erythema multiforme 3- Immunologic abnormalities in the serum: . Speckled pattern of antinuclear antibody (ANA) . Anti-La (SSB) antibody . Positive rheumatoid factor (RF)
Rowell Syndrome (RS) • Since its first description in 1963 by Rowell et al , Rowell Syndrome has been reported in 37 patients, often not respecting the initial criteria…. • Some authors postulate that RS represent a subset of SCLE with targetoid lesions.
Subacute cutaneous lupus erythematosus(SCLE) • First described by Sontheimer et al in 1979 as a distinct subset of cutaneous lupus characterized by: 1- Psoriasiform or annular lesions 2- Mild systemic involvement 3- Anti-Ro (SSA) antibodies 4- Associated with HLA-DR3
