Background: The psychiatric manifestations of Sjögren’s syndrome are often overlooked despite their prevalence. They can be revelatory of the disease and include anxiety, depression, dementia and, rarely, psychosis. Case description: We report a case of 18-year-old female in whom a major depressive syndrome revealed primary Sjögren’s disease, with a favourable outcome after treatment with rituximab. Conclusion: The diagnostic of Sjögren’s syndrome should be considered in patients who present with unexplained and refractory neuropsychiatric symptoms, even in the absence of sicca symptoms.

Background: Systemic lupus erythematosus (SLE) is a multisystem autoimmune disease, characterised by multi-organ affections. Haematological involvement is a common manifestation of SLE, consisting of autoimmune peripheral cytopenia. Autoimmune myelofibrosis (AIMF) is a rare cause of cytopenia in SLE; it could precede or be concurrent with the diagnosis of SLE. There are few studies that describe this association. Case description: We report a case of AIMF revealing the diagnosis of SLE in a 34-year-old female, presented with episodes of gingival bleeding associated with peripheral inflammatory polyarthralgia, photosensitivity and deterioration of general condition. Clinical examination revealed a soft pitting oedema in the lower limbs. Laboratory investigations showed a pancytopenia, inflammatory biological syndrome, with positive 24-hour proteinuria and anti-native DNA antibodies. A bone marrow biopsy showed diffuse myelofibrosis associated with maturation disorders and no tumour infiltrate. Renal biopsy revealed proliferative glomerulonephritis class III with immune deposits. Conclusion: The association of AIMF with SLE has been rarely reported, and it could be another cause for cytopenia in SLE.

Introduction: Vitamin C deficiency (or scurvy) usually takes weeks to become apparent as cutaneous signs and impaired wound healing. Haemorrhagic pericarditis remains a rare complication of scurvy, which has never been reported as an isolated condition. We report the case of a haemorrhagic pericarditis revealing a vitamin C deficiency in a 56-year-old patient. Case description: A 56-year-old woman presented with a 2-week history of worsening chest pain and dyspnoea, with no significant medical history. Upon admission, the patient exhibited tachycardia, tachypnoea, low blood pressure, elevated jugular venous pressure, muffled heart sounds and multiple petechiae on her lower limbs. An ultrasound revealed a large pericardial effusion, and an emergency pericardiocentesis was performed, which yielded haemorrhagic fluid without atypical cells. An initial workup including haemoculture, PT and PTT, tuberculosis workup, autoantibodies, tumour markers and infectious disease was negative. A whole-body CT scan showed no evidence of tuberculosis or lymphoma. Additional testing showed that her vitamin C level was

Necrotizing fasciitis is a serious soft tissue infection that causes necrosis of the subcutaneous tissues and the muscle fascia. It is associated with a high mortality rate of around 25%. Necrotizing fasciitis of the breast is a rare entity. It is a rapidly progressive life-threatening condition which can lead to sepsis with multiple organ failure. We describe a case of necrotizing fasciitis of the right breast in a 48-year-old patient diagnosed with systemic sclerosis–rheumatoid arthritis overlap syndrome.

Introduction: Myasthenia gravis is a rare autoimmune disease caused by autoantibodies directed against the synapses of the neuromuscular junction. Patient and methods: We report the case of a young patient with myasthenia gravis associated with Hodgkin's lymphoma. Results: A 22-year-old patient presented with a 2-month history of severe weakness associated with muscle fatigability and intermittent ptosis without dysphonia or respiratory signs. Clinical examination revealed generalized myasthenia. The EMG did not show post-synaptic block, and anti-acetylcholine receptor antibodies were elevated at 3 nmol/l (normal ?0.3 nmol/l). CT of the thorax showed an anterior medial mass. Immunohistochemistry of the mass revealed mixed cellularity Hodgkin’s lymphoma. Conclusion: The association of lymphomas with myasthenia gravis has been rarely reported.
