RESUMEN

Introduction: Behçet's disease is a systemic vasculitis characterized by a large clinical polymorphism with a particular frequency of cutaneous signs. Sweet's syndrome is a neutrophilic dermatosis marked by the sudden appearance of painful skin lesions in the form of erythematous papules, nodules or plaques. This syndrome is associated with high fever, neutrophilia and histologically a diffuse infiltrate of neutrophils in the dermis. Observation: We report the case of a 43-year-old patient followed for Behçet's disease, who developed cutaneous plaques of neutrophilic dermatosis of both upper limbs. The clinical and biological picture was in favor of Sweet's syndrome. Conclusion: The coexistence of Sweet's syndrome and Behçet's disease is already reported in the literature. The association is however very rare given the differences in the clinical and pathogenic features between the two conditions. LEARNING POINTS: The appearance of neutrophilic dermatosis during a skin flare-up of Behçet's disease alerted us to a possible link between Sweet's syndrome and Behçet's disease.The morphology of the skin lesions associated with these pathologies is heterogeneous, making diagnosis sometimes difficult.Cases reported in the literature concerning the association between Sweet's syndrome and Behçet's disease are rare.

RESUMEN

Amyopathic dermatomyositis is a rare form of dermatomyositis characterized by cutaneous lesions without clinical, biological, or histological muscular involvement. Pulmonary complications associated with this condition are diffuse interstitial lung disease (ILD), pneumomediastinum, and spontaneous pneumothorax. The form associated with anti-melanoma differentiation-associated protein 5 (anti-MDA-5) antibodies is reputed to have a poor prognosis and is responsible for ILD which can rapidly progress to fatal respiratory failure. Treatment of amyopathic dermatomyositis is essentially based on corticosteroid therapy and immunosuppressants. We present the case of a 42-year-old patient followed for three months for diffuse ILD. The patient was hospitalized for respiratory distress secondary to an aggravation of ILD with pneumomediastinum and pneumothorax. The patient also presented with cutaneous lesions identified as Gottron's papules. The patient was diagnosed with amyopathic dermatomyositis positive for anti-MDA-5 antibodies.

RESUMEN

BACKGROUND: The association of inflammatory myopathy and myasthenia gravis is a rarely described entity whose clinical presentation has always been intriguing because of the great clinical similarity between these two pathologies. The presence of a thymic pathology often explains this combination, whose mechanisms are very complex. CASE PRESENTATION: A 56-year-old woman of North African origin, was hospitalized to explore the Raynaud phenomenon associated with proximal muscle weakness, pain, and arthralgia. There was no rash, and neuromuscular examination had revealed proximal tetraparesis and mild neck weakness. Tendon reflexes were normal. There was no abnormal nail fold capillaroscopy. A significant titer of muscle enzymes had been shown on blood tests, and autoimmune screening for myositis-specific and myositis-associated autoantibodies was negative. Electromyography had shown a myopathic pattern, and muscle biopsy confirmed an inflammatory myopathy. Although steroids were introduced, the clinical course was unsatisfactory; ophthalmic and bulbar symptomatology appeared. The association of myasthenia gravis was confirmed by an elevated level of serum acetylcholine receptor. A chest computed tomography scan had identified a thymoma. Treated with prednisone, pyridostigmine, and thymectomy, the patient's clinical and biological evolution was favorable. CONCLUSION: This case illustrates an exceptional association of two entities and the difficulty encountered during their diagnosis and treatment. The management of these two diseases is different, so it is essential to recognize this concomitant presentation.

RESUMEN

We report in this manuscript a case of newborn baby with asymptomatic form of congenital malaria; the screening of the peripheral blood smear of the baby after a positive result in the mother allowed the diagnosis. The authors were permitted through this case to discuss the therapeutic possibility in these cases.

RESUMEN

We report the case of Conn adenoma revealed by tetraparesis in a 33-year old pregnant woman at the 16thweek of amenorrhea. The patient had a blood pressure of 147/87 mmHg, which was considered high-normal, hypokalemia at 1.1 mmol/l. The diagnosis was confirmed by hormone dosage which showed elevated plasma aldosterone levels and decreased plasma renin activity. MRI showed a left adrenal nodule, 1.5 cm in diameter, compatible with adrenal adenoma. Left adrenalectomy was performed with simple postoperative course and normalization of kalemia and blood pressure.
