Sarcoidosis is a systemic granulomatous disease in which medullary involvement is a rare extrapulmonary manifestation. We present the case of a 37-year-old man with right abdominal and dorso-lumbar pain lasting for months. Computerized tomography showed renal microlithiasis and retroperitoneal, hilar and mediastinal adenopathies. Laboratory results showed an elevated erythrocyte sedimentation rate, IgG, ?2-microgobulin and angiotensin-conversion enzyme, serum calcium in the upper limit and hypercalciuria. There was a slight elevation of the CD4/CD8 ratio in bronchoalveolar lavage, without lymphocytic alveolitis. An endobronchial ganglion biopsy was inconclusive. A positron emission tomography scan demonstrated supra and infra-diaphragmatic, splenic and medullary involvement, suggesting lymphoproliferative disease (LPD). A bone marrow biopsy (BMB) revealed sarcoid-like epithelioid cell granulomas, excluding LPD. Sarcoidosis was assumed and corticosteroids were started. Although cytopenias were not present, the extensive ganglion, splenic and medullary involvement made LPD exclusion imperative, while BMB allowed for a definitive diagnosis.

Neurosyphilis refers to the involvement of the central nervous system by Treponema pallidum . Ocular syphilis can present with a range of manifestations, uveitis being the most common, and it can occur at any stage of acquired syphilis. There are multiple tests available for the diagnosis of syphilis. Moreover, the treatment of syphilis depends upon the stage of the disease. For years, the management of syphilitic uveitis was controversial among physicians, with several reviews debating whether ocular syphilis is a subtype of neurosyphilis. Recent recommendations state that ocular syphilis should be treated similarly to neurosyphilis, even with a normal liquor examination. Herein, we describe a case of a 57-year-old male patient who was diagnosed with ocular syphilis.

Macrocytosis is defined as a mean corpuscular volume greater than 100 femtolitres (fL). There are several causes for macrocytic anaemia, and they can be divided into megaloblastic or non-megaloblastic anaemia. Vitamin B12 deficiency is one of the most common causes of megaloblastic anaemia.The cause of vitamin B12 deficiency must be evaluated including the presence of pernicious anaemia as it could alter the treatment and follow-up.Pernicious anaemia can be associated with other autoimmune diseases constituting polyglandular syndromes.

Hepatocellular carcinoma is common in patients with cirrhosis regardless of the etiology. Its presentation is uncommon in patients without known cirrhosis. It can spread commonly to the lungs, abdominal lymph nodes and bone but cardiac metastases are rare. The screening and early diagnosis impact the treatment feasibility and prognosis. The most common etiologies of cirrhosis and hepatocellular carcinoma are alcohol consumption and viral hepatitis B and C, however, non-alcoholic fatty liver disease (NAFLD) is becoming a more pronounced known risk factor for steatosis, advanced liver fibrosis, cirrhosis, and thus hepatocellular carcinoma due to the rise of metabolic syndrome prevalence. Although a known risk factor, there are no current recommendations for cancer surveillance in patients with NAFLD. The aim of this paper is to raise awareness of this rising complication by describing a rare initial presentation of hepatocellular carcinoma.
