7 CCLE: kronisk kutan LE (=DLE) - etterlater arr ! A 52 year old woman with a long history of photosensitivity and facial skin rashes treated by a dermatologist presented with proteinuria and facial skin lesions in a butterfly distribution as shown in the picture. The differential diagnosis consists of: 1. Acute butterfly skin rash of lupus erythematosus 2. Atrophic skin changes due to local corticosteroid treatment Wrong answer 3. Chronic lupus erythematosus with a butterfly appearance 4. Combination of skin lesion due to chronic lupus erythematosus and local treatment with corticosteroids.CCLE: kronisk kutan LE (=DLE) - etterlater arr !
8 Hypergammaglobulimeniske purpura ved prim Sjøgren (cf Waldenstrøm) A 58 year-old woman with a history of Sjögren’s syndrome (SS) for the last 10 years presented to Rheumatology Clinic with a skin rash involving the lower extremities. Clinical examination revealed bilateral parotid gland enlargement and palpable purpura over the extensor surfaces of the lower extremities. Antinuclear antibodies (ANA) were 1/1280 with a fine speckled pattern, IgM rheumatoid factor (RF) was 1/320 and antibodies to Ro (SSA) and La (SSB) were also positive. The differential diagnosis for the palpable purpura in this patient comprises: 1. Hypergammaglobulinemic purpura 2. Idiopathic thrombocytopenic purpura Wrong answer 3. Waldenström macroglobulinemia 4. T-cell lymphoma Hypergammaglobulimeniske purpura ved prim Sjøgren (cf Waldenstrøm)

15 A 55 year old woman with a history of “bronchial asthma”, recurrent iritis and articular chondritis presented with a high fever. Clinical examination revealed a dyspnoiec patient with a moon face and a saddle-shaped nose with diffuse wheezing bilaterally over the lungs. Laboratory evaluation showed leukocytosis with polymorphonuclearcytosis, high ESR, high CRP, and negative ANCA. The chest X-ray was normal. The differential diagnosis consists of: 1. Relapsing polychondritis 2. Cogan’s syndrome 3. Wegener's granulomatosis Wrong answer 4. Systemic vasculitis (Churg-Strauss syndrome) Saddle nose : trauma / polykondritt / Wegener’s granuolomatosis/ syfilis/ kokaine misbruk
18 A single 35 year-old woman with a history of Raynaud’s phenomenon since 1990 came to the Rheumatology outpatient clinic for evaluation. Her past medical and family history were unremarkable. Physical examination showed that the hands were cold with a bluish appearance and livedo reticularis was present on the lower extremities (figure). Immunological evaluation showed: positive antinuclear antibodies at low titer (1/80), positive anticardiolipin antibodies, both IgG and IgM (280 IU and 150 IU respectively, normal value <100 IU). The rest of the immunological evaluation was negative. What is the differential diagnosis? 1. Systemic lupus erythematosus 2. Progressive systemic sclerosis Wrong answer 3. Primary antiphospholipid syndrome 4. Atrophic blanche A number of conditions may cause the appearance of livedo reticularis:Cutis marmorata telangiectatica congenita a rare congenital conditionSneddon syndrome - association of Livedoid vasculitis and systemic vascular disorders, such as strokes, due to underlying genetic cause.Idiopathic livedo reticularis - is the commonest cause of livedo reticularis appearance and is a completely benign condition of unknown cause affecting mostly young women during the winter. May be mild, but ulceration may occur later in the summer.Secondary livedo reticularis:Vasculitis autoimmune conditions:Livedoid vasculitis - with painful ulceration occurring in the lower legsPolyarteritis nodosaSystemic lupus erythematosusDermatomyositisRheumatoid arthritisLymphomaPancreatitisTuberculosisAmantadine (drug)Obstruction of capillaries:Cryoglobulinaemia - proteins in the blood that clump together in cold conditions.Antiphospholipid syndrome due to small blood clotsHypercalcaemia (raised blood calcium levels which may be deposited in the capillaries)Haematological disorders of Polycythaemia rubra vera or Thrombocytosis (excessive red cells or platelets)Infections (syphilis and tuberculosis)Arteriosclerosis (cholesterol emboli) and homocystinuria (due to Chromosome 21 autosomal recessive Cystathionine beta synthase deficiency)Intra-arterial injection (especially in drug addictsLivedo reticularis
