Pancytopenia in sarcoidosis

A man in his 80s with a history of sarcoidosis on chronic prednisone presented to the emergency department with several days of dyspnoea. A chest X-ray showed signs of pneumonia, and the patient was admitted. Blood and pleural fluid cultures grew Nocardia farcinica ; therefore, the patient was started on treatment with trimethoprim-sulbactam and imipenem. Brain imaging showed evidence of dissemination of the infection to the central nervous system (CNS). The patient's admission was complicated by pleural effusions, acute kidney injury and pancytopenia, and therefore, his antibiotic regimen was ultimately transitioned from trimethoprim-sulfamethoxazole (TMP-SMX), meropenem and linezolid to imipenem and tedizolid...

Sarcoidosis presents in a variety of ways, but historically, renal involvement has been considered rare with an incidence of 0.7% and is seldom the presenting feature of the illness. Concomitant involvement of kidney and bone marrow is extremely rare. Atypical forms of presentation, such as in this case, may pose a true diagnostic challenge. A 20-year-old African-American male presented to the emergency department with vague symptoms including fatigue, malaise, anorexia, right-sided lower back pain, and nausea...

Sarcoidosis is a systemic inflammatory disease that can cause granulomatous infiltration of almost all organs and tissues which allows for a wide variety of presentations that may overlap with other disease processes. Renal sarcoidosis is a much rarer site of extrapulmonary involvement and may present as hypercalcemia, tubular or glomerular dysfunction, and/or granulomatous interstitial nephritis. Prompt diagnosis of sarcoidosis is crucial for initiating appropriate treatment and avoiding organ dysfunction...

Sarcoidosis is a systemic inflammatory disease characterized by noncaseating epithelioid cell granulomas. However, certain infections can exhibit similar histological findings. We present a case of a 69-year-old man who was initially diagnosed with sarcoidosis and later was confirmed, through 16S rRNA sequencing, to have disseminated Mycobacterium genavense infection. Acid-fast bacteria were detected in the bone marrow biopsy using Ziehl-Neelsen staining, but routine clinical tests did not provide a definitive diagnosis...

Pancytopenia is a hematologic condition characterized by a decrease in all three peripheral blood cell lines. There are many causes of pancytopenia, and the proper approach is required for accurate diagnosis. Brucellosis and systemic lupus erythematosus (SLE) are both diseases that can initially present as pancytopenia, both of which require a targeted workup to diagnose. Due to the immune system's complexity, many distinct diseases may have similar symptomatology. Furthermore, infections and rheumatological diseases can stimulate the same molecular pathways and trigger T and B cells...

An 83-year-old woman with asymptomatic pulmonary sarcoidosis presented to our hospital with fever and malaise for three months. Abdominal CT showed splenomegaly, and bone marrow examination revealed non-caseating granulomas. Pancytopenia was diagnosed due to bone marrow and splenic lesions of sarcoidosis. Steroid pulses were administered, but the patient died without response to treatment. Pathological autopsy results showed non-caseating granulomas and hemophagocytosis in the spleen and bone marrow. This suggested hemophagocytic syndrome, which was not suspected before death, in addition to sarcoidosis...

BACKGROUND: Sarcoidosis is a systemic inflammatory disease that is characterized by non-caseating epithelioid-cell granulomas upon histology. However, similar histological findings may also be seen with certain infections. Thus, differentiation from infection is pivotal to ensure appropriate treatment. Here, we present a case of a disseminated infection with Mycobacterium genavense owing to an interleukin 12 receptor subunit beta 1 (IL-12Rβ1) associated immunodeficiency in a previously healthy female who was initially misdiagnosed with sarcoidosis...

Sarcoidosis is a multisystem inflammatory chronic disorder that can virtually affect any organ system in the body. Most commonly affected organs are the intrathoracic structures with 90% of the reported cases involving the lungs. Esophageal involvement in sarcoidosis is extremely rare. Involvement of the esophagus and kidney along with hematological involvement is extremely uncommon in the same patient. Here, we present a case of a 58-year-old gentleman with a similar rare presentation. The patient presented with shortness of breath, productive cough, fatigue, and difficulty in swallowing, along with a weight loss of 20-30 pounds over three months...

Secondary infections in coronavirus disease (COVID) are becoming common. We report a case of a female known case of diabetes, sarcoidosis on steroids and methotrexate admitted with COVID pneumonia. She was treated with steroids, remdesivir, and anticoagulants and was discharged. She revisited the hospital after 2 months with complaints of severe right-sided headache, eye pain, and vomiting. Magentic resonance image of brain and paranasal sinus revealed possibility of invasive rhinosinus mucormycosis. Functional endoscopic sinus surgery (FESS) was done and culture showed growth of mucor and methicillin resistant staphylococcus aureus (MRSA) following which she was started on amphotericin B and antibiotics...

Renal and bone marrow involvements in sarcoidosis are rare. We experienced the case of a 67-year-old man with systemic sarcoidosis, with bone marrow involvement, hepatic involvement and a unique constellation of renal lesion with cellular crescent formation. Immunosuppressive therapy was helpful for maintaining the stability of his pancytopenia, hepatic function and renal function. To the best of our knowledge, the association between sarcoidosis, bone marrow involvement and crescentic glomerulonephritis has been reported in only few cases in literature...

We describe a case of fever of unknown origin (FUO), renal failure, and pancytopenia. Initially, lymph proliferative disorder was suspected; therefore, bone marrow biopsy and 18F-fluorodeoxyglucose (18F-FDG) positron emission tomography/computed tomography (PET/CT) were performed. Bronchoscopy and lung biopsy were performed because of abnormal FDG uptake in both lung fields. Imaging data and laboratory and histological results confirmed sarcoidosis with bone marrow invasion. The patient was discharged after favorable response to corticosteroid therapy...

We examined a 22-year-old woman who was admitted to our hospital with abdominal distention. At 19 years of age, the patient presented with hepatosplenomegaly. She was examined several times in another hospital; however, the cause was unidentified. Our evaluation showed severe pancytopenia and a spleen 13×24 cm in size. The serum levels of angiotensin-converting enzyme and lysozyme were elevated. She was diagnosed with liver sarcoidosis based on non-caseating epithelioid granuloma in liver biopsy tissue...

A 46-year-old woman presented with massive hematemesis, caused by the rupture of esophageal varices. The laboratory investigations showed pancytopenia, and imaging tests revealed hepatosplenomegaly and ascites. A diagnosis of systemic sarcoidosis was made based on biopsies of the liver, stomach, lungs, heart, and skin. Although fat deposition was predominant, non-caseating granuloma and cirrhotic changes were found in the liver. Non-caseating granuloma was also identified in a biopsy specimen from minute depressions of the gastric folds...

An Afro-Caribbean woman presented with worsening breathlessness, weight loss, lethargy and fevers, developing a bilateral florid erythematous rash on her legs. She was recently diagnosed with rheumatoid arthritis and bilateral hilar lymphadenopathy was found on thoracic CT imaging. She was tachycardic and investigations revealed pancytopenia, eosinophilia, raised serum ACE, acute kidney injury and deranged liver function tests. Biopsy of the lymphadenopathy revealed mixed lymphoid cells and liver biopsy revealed extramedullary haematopoiesis, with hypercellular marrow found on bone marrow biopsy...

INTRODUCTION: Histoplasmosis is an endemic mycosis with most cases of clinical illness reported in North and Central America. Rarely, patients develop progressive disseminated histoplasmosis with extrapulmonary manifestations. These infections are fatal if not appropriately treated. CASE PRESENTATION: We report a case of progressive disseminated histoplasmosis presenting with fever, progressive dyspnea, and pancytopenia in a 51-year-old Caucasian man who had been treated with chronic steroids for a diagnosis of sarcoidosis made 20 years previously...

INTRODUCTION: Sarcoidosis is a multisystem granulomatous disease of unknown etiology. Although hepatic granulomas occur in 50-65% of patients with systemic sarcoidosis, isolated liver sarcoidosis is rare. Clinical presentation varies from asymptomatic to manifest. The diagnosis is based on a characteristic histopathological finding of liver biopsy. CASE REPORT: We reported a 69-year old man was admitted due to abdominal swelling and abdominal pain. Laboratory studies detected: cholestasis, pancytopenia and elevaton of angiotensin-converting enzyme...

To date, anti-tumor necrosis factor alfa (anti-TNF-α) therapy is the only alternative to nonsteroidal anti-inflammatory drugs for the treatment of ankylosing spondylitis. Etanercept is a soluble TNF receptor, with a mode of action and pharmacokinetics different to those of antibodies and distinctive efficacy and safety. Etanercept has demonstrated efficacy in the treatment of ankylosing spondylitis, with or without radiographic sacroiliitis, and other manifestations of the disease, including peripheral arthritis, enthesitis, and psoriasis...

Clinical presentation of sarcoidosis in children is very variable and dependant upon age. Herein, we report the first association of massive splenomegaly and pancytopenia as the revealing mode of sarcoidosis in an 8-year-old girl who, despite bone marrow involvement, had a remarkable good outcome following steroid therapy.

A 39-year-old male reported fevers, weight loss, watery loose stools, and decreased visual acuity in his right eye over the prior five years. He was pancytopenic, had an elevated American council on exercise level, total bilirubin, and alkaline phosphatase. Computed tomography revealed massive hepatosplenomegaly and emphysematous lung changes. Liver biopsy showed non caseating granulomas. The patient was diagnosed with extrapulmonary sarcoidosis and was treated with prednisone. The patient symptomatically improved but 5 mo later presented with abdominal pain caused by perforation of the cecum...

Bone marrow infiltration by granulomas rarely presents with cytopenias and is usually a result of atypical infections, lymphomas, or sarcoidosis. Drugs are also an important but often overlooked causal agent of bone marrow granulomas. Although rare, amiodarone has been associated with bone marrow granuloma formation. This case report describes a 73-year-old male who presented with pancytopenia during a preoperative evaluation. Amiodarone therapy was suspected to be the causal agent after diagnostic evaluation and exclusion of other causes...
