RESUMEN
Systemic sclerosis (SSc) is characterized by the presence of microvascular disease and various patterns of cutaneous and parenchymal fibrosis. Manifestation of SSc may occur in numerous tissues and organs and can be particularly problematic when present in the lungs, kidneys or heart. Cardiac involvement in SSc includes pericarditis, myocardial disease, conduction abnormalities, and arrhythmia. Sick sinus syndrome is described as a combination of symptoms (dizziness, confusion, fatigue, syncope and congestive heart failure) caused by sinus node dysfunction and manifested by marked sinus bradycardia, sinoatrial block, or sinus arrest. Sinus node dysfunction is most often seen in the elderly but also, rarely, in systemic amyloidosis and connective tissue disease. Sick sinus syndrome is rarely found in patients with SSc, of which there has been only one case report, according to a review of the literature. Therefore, we report a case of sick sinus syndrome in a 71-year-old female with SSc.

Although tumor necrosis factor (TNF)-alpha antagonist is a successful treatment modality for various autoimmune diseases, including rheumatoid arthritis (RA), ankylosing spondylitis and psoriatic arthritis, many adverse effects have been reported. Cutaneous adverse reactions of TNF-alpha antagonist include skin rash, urticaria, lupus like rash, seborrheic dermatitis and different kinds of psoriasiform dermatitis. We report a case of psoriasiform dermatitis during TNF-alpha antagonist treatment in a 50-year-old woman with RA. The patient has been treated with adalimumab. After 2 months, she developed pruritic erythematous eruption and desquamative lesions on the head and limbs, which were defined as psoriasiform change by a skin biopsy. These skin lesions are successfully treated with combination therapy, including cessation of adalimumab, corticosteroid and phototherapy.
