We report the case of a patient with Rheumatoid Arthritis [RA] presenting with clinical-pathological and radiological features of Pulmonary Lymphomatoid Granulomatosis (PLG). This is a rare lung disorder characterized by multiple nodular lesions with lymphocytic invasion of vascular walls. We present one such case of PLG secondary to Methotrexate and Azathioprine therapy, who was successfully treated with Steroids and Rituximab. We wish to highlight the importance of lung biopsy in the diagnosis and the use of rituximab as a treatment modality for RA as well as PLG.Electronic supplementary materialThe online version of this article (doi:10.1186/2193-1801-3-751) contains supplementary material, which is available to authorized users.

We report the case of a man presenting with clinical features of a mononeuritis multiplex, a perinuclear-ANCA (p-ANCA), and a renal biopsy suggestive of Wegener granulomatosis (WG). We wish to highlight this case as a learning point for clinicians as WG rarely presents in this form, and can be easily overlooked as a cause of mononeuritis multiplex.

SUMMARYPeriodic thyrotoxic paralysis is a genetic condition, rare in the West and in Caucasians. Thyrotoxicosis, especially in western hospitals, is an easily overlooked cause of sudden-onset paralysis. We present a case of a 40-yearold man who awoke one morning unable to stand. He had bilateral lower limb flaccid weakness of 0/5 with reduced reflexes and equivocal plantars; upper limbs were 3/5 with reduced tone and reflexes. ECG sinus rhythm was at a rate of 88/min. PR interval was decreased and QT interval increased. Bloods showed potassium of 1.8 mEq/L (normal range 3.5-5), free T4 of 29.2 pmol/L (normal range 6.5-17) and thyroidstimulating hormone (TSH) of <0.01 mIU/L (normal range 0.35-4.94). Random urinary potassium was 8.8 mEq/L (normal range 12.5-62.5). The patient was admitted initially to intensive therapy unit and given intravenous potassium. His symptoms resolved within 24 h. He was diagnosed with thyrotoxic periodic paralysis. He was discharged on carbimazole and propanolol, and follow-up was arranged in the endocrinology clinic. BACKGROUND

We report a case of a 56-year-old female with a confirmed diagnosis of Dermatomyositis on muscle biopsy, which was refractory to 5 different disease modifying drugs as well as intravenous immunoglobulins and symptoms improved dramatically with a single course of Rituximab. We hereby wish to highlight the importance of Rituximab in this highly resistant case and that anti CD 20 biologic drugs can be considered as standard treatment protocol in refractory Dermatomyositis.

We hereby present a case of anaemia in a 73 years old patient with known past medical history of diffuse systemic scleroderma, who presented with acute onset of dizziness and haemetemesis. Blood tests revealed sudden drop of haemoglobin and an urgent gastroscopy revealed gastric antral vascular ectasia (GAVE) or “watermelon stomach”. GAVE is a rare but well recognised cause of acute bleeding in systemic scleroderma patients and should be kept as a differential diagnosis in the work up of anaemia in these patients.
