ABSTRACT
OBJECTIVE: This article provides an overview of the neurologic manifestations of sarcoidosis and select rheumatologic disorders. An approach to the assessment and differential diagnosis of characteristic clinical presentations, including meningitis and vasculitis, is also reviewed. A review of treatment options is included as well as discussion of distinct areas of overlap, including rheumatologic disease in the setting of neuromyelitis spectrum disorder and demyelinating disease in the setting of tumor necrosis factor-α inhibitors. LATEST DEVELOPMENTS: An increased understanding of the immune mechanisms involved in sarcoidosis and rheumatologic diseases has resulted in a greater diversity of therapeutic options for their treatment. Evidence directing the treatment of the central nervous system (CNS) manifestations of these same diseases is lacking, with a paucity of controlled trials. ESSENTIAL POINTS: It is important to have a basic knowledge of the common CNS manifestations of rheumatologic diseases and sarcoidosis so that they can be recognized when encountered. In the context of many systemic inflammatory diseases, including systemic lupus erythematosus, IgG4-related disease, and sarcoidosis, CNS disease may be a presenting feature or occur without systemic manifestations of the disease, making familiarity with these diseases even more important.

BACKGROUND: Hypercalcaemia is a common manifestation of sarcoidosis but is sparingly described in gastrointestinal stromal tumours (GISTs). We describe a case of acute kidney injury and hypercalcemia resulting from simultaneous diagnosis of GIST and sarcoidosis, the presentation of which has not yet been reported. CASE PRESENTATION: A 61-year-old male presented with acute kidney injury and hypercalcemia, with elevated 1,25-dihydroxyvitamin D levels. Investigations demonstrated a large gastric antral mass which was resected and proven to be GIST. Histopathology of incidentally found liver nodules revealed non-necrotising epithelioid granulomas consistent with concomitant sarcoidosis. The hypercalcemia was successfully treated with bisphosphonate therapy, resection of the GIST and a four month course of corticosteroids, which was truncated due to a mycobacterial infection. CONCLUSIONS: Our case report is the first to describe hypercalcemia due to GIST and biopsy-proven sarcoidosis, thereby raising the possibility of a common pathophysiological pathway relating the two entities. We review the literature describing the mechanisms of hypercalcaemia in GIST and the association between GIST and sarcoidosis.

Neurosarcoidosis can manifest in various neurological presentations. The occurrence of cavernous sinus involvement in neurosarcoidosis is rare, which can complicate the diagnostic process. We present a case of neurosarcoidosis demonstrating progressively deteriorating right cavernous sinus syndrome in a woman in her 50s, affecting the oculomotor, abducens and the ophthalmic division of the trigeminal nerves. MRI demonstrated meningeal thickening along the lateral wall of the right cavernous sinus, and a pan-CT scan of the chest, abdomen and pelvis revealed disseminated sarcoidosis involving the lungs and the liver. Histopathological analysis of the liver lesion ultimately confirmed the diagnosis of sarcoidosis. This case underscores the significance of considering neurosarcoidosis as a potential cause of cavernous sinus syndrome. In such cases, early initiation of corticosteroid treatment, with or without steroid-sparing agents, is crucial to prevent disease progression and relapse.

Granulomatous mastitis (GM) is a long-term inflammatory disease of the breast that usually occurs in women of reproductive age. Autoimmune mastitis is one of the most common pathological breast conditions necessitating tailored treatment. However, GM as a first clinical manifestation of sarcoidosis is uncommon. Simultaneous occurrence of GM, erythema nodosum (EN), and arthritis, termed "GMENA" syndrome, is a rare clinical entity associated with autoimmune rheumatic diseases. Herein, we report the case of a 31-year-old female patient with GMENA syndrome, who presented with a painful nodule of the left breast. Initial treatment entailed antibiotics under the presumption of a breast abscess, yielding negligible improvement. During this period, the patient developed polyarthritis and bilateral EN on the lower extremities. Histopathologic examination of the breast tissue exhibited noncaseating granulomas. The patient responded positively to prednisolone and methotrexate treatment. Literature review revealed a coherent pattern across GMENA cases. Our findings suggest that the "GMENA" syndrome represents a unique acute manifestation of sarcoidosis and highlight the necessity for heightened awareness, accurate diagnosis, and tailored therapeutic approaches for GMENA syndrome. Further research is warranted to elucidate its cause and optimize patient management. This case highlights the importance of identifying and effectively managing such interrelated clinical presentations.

Sarcoid -like reactions (SLRs) can occur in several malignancies adjacent to primary tumour location or the draining lymph nodes. The presence of peritumoural and intratumoural SLR in patients suffering from renal cell carcinoma (RCC) has been reported in few instances. However, the association of RCC with SLR in spleen, liver and other organs in the absence of systemic sarcoidosis is very rare.We present an unusual case of a gentleman in his 30s, who presented with a lesion in the left kidney along with non-specific lesions (likely granulomatous) in liver, spleen and lungs. Partial Nnephrectomy specimen confirmed conventional/clear cell RCC. The histopathology revealed an extensive epithelioid granulomatous reaction affecting both peritumoural and intratumoural areas. Follow-up images demonstrated an almost complete resolution of lesions in the spleen, liver and lungs. Our case supports the hypothesis that non-caseating granulomas of SLR could be a manifestation of an immunologically mediated antitumour response.

BACKGROUND: Sarcoidosis-associated pulmonary hypertension (SAPH) is listed in Group 5 of the clinical classification of pulmonary hypertension, due to its complex and multifactorial pathophysiology. The most common cause of SAPH development is advanced lung fibrosis with the associated destruction of the vascular bed, and/or alveolar hypoxia. However, a substantial proportion of SAPH patients (up to 30%) do not have significant fibrosis on chest imaging. In such cases, the development of pulmonary hypertension may be due to the lesions directly affecting the pulmonary vasculature, such as granulomatous angiitis, pulmonary veno-occlusive disease, chronic thromboembolism or external compression of vessels by enlarged lymph nodes. Based on the case of a 69-year-old female who developed SAPH due to pulmonary arteries stenosis, diagnostic difficulties and therapeutic management are discussed. CASE PRESENTATION: The patient, non-smoking female, diagnosed with stage II sarcoidosis twelve years earlier, presented with progressive dyspnoea on exertion, dry cough, minor haemoptysis and increasing oedema of the lower limbs. Computed tomography pulmonary angiography (CTPA) showed complete occlusion of the right upper lobe artery and narrowing of the left lower lobe artery, with post-stenotic dilatation of the arteries of the basal segments. The vascular pathology was caused by adjacent, enlarged lymph nodes with calcifications and fibrotic tissue surrounding the vessels. Pulmonary artery thrombi were not found. The patient was treated with systemic corticosteroid therapy and subsequently with balloon pulmonary angioplasty. Partial improvement in clinical status and hemodynamic parameters has been achieved. CONCLUSIONS: An appropriate screening strategy is required for early detection of pulmonary hypertension in sarcoidosis patients. Once SAPH diagnosis is confirmed, it is crucial to determine the appropriate phenotype of pulmonary hypertension and provide the most effective treatment plan. Although determining SAPH phenotype is challenging, one should remember about the possibility of pulmonary arteries occlusion.

BACKGROUND: Sarcoidosis can be associated with stroke. Whether granulomatous vasculitis directly causes stroke in patients with sarcoidosis remains unclear. This systematic review aims to consolidate reports of concurrent sarcoidosis and stroke. METHODS: Medline and Embase were searched for terms encompassing sarcoidosis and stroke with a censoring date of March 25, 2023. Cases were reviewed by two authors, with the inclusion criteria: biopsy-confirmed systemic sarcoidosis, stroke confirmed by imaging or pathology, clinical description of individual patient history, and English language publications. RESULTS: Of 1628 articles screened, 51 patients from 49 articles were included (65% male, mean age 41 years). Seventy-one percent of strokes were ischemic and 29% were hemorrhagic. Lesions were supratentorial in 78% of cases, infratentorial in 34%, and multifocal in 45%. Presenting symptoms were variable, with the most common being headache (38%) followed by weakness (35%). 10 patients had recurrent strokes. Stroke was the presenting symptom of sarcoidosis in 65%. 21 patients had brain biopsies. The most common neuropathologic findings were perivascular (33%) or intramural (33%) non-caseating granulomas. On imaging, 32 patients had findings suggestive of neurosarcoidosis, including 35% with evidence of meningeal enhancement. 63% of patients were treated with corticosteroids and/or other immunomodulatory therapy, with varying clinical improvement. CONCLUSIONS: Stroke associated with sarcoidosis generally follows trends in stroke incidence, with infarction being more common than hemorrhage and male sex carrying a higher risk. Most patients were diagnosed with sarcoidosis during or following their stroke episode. Brain biopsy infrequently shows clear granulomatous vasculitis.

OBJECTIVES: Sarcoidosis is a multi-system granulomatous disease of unknown origin. It is mainly thought of as a lung disease but it can affect any organ system. Sinus and endocrine dysfunctions are described but are rare and seldomly linked with sarcoidosis. METHODS: Here we describe a case of a young Caucasian man who already visited multiple care givers for sinusitis, erectile dysfunction and anorexia. He presented at the emergency department with fever and emaciation, polyuria and polydipsia. The results of the blood sampling revealed a hypercalcaemia as well as abnormal thyroid function. RESULTS: After biochemical, radiological and histopathological workup, he was diagnosed with pulmonary sarcoidosis. Treatment with corticosteroids resulted in resolution of the sinusitis and normalisation of the calcemia, as well as the thyroid function while the impotence, polydipsia and polyuria remained. Elaboration revealed extra-pulmonary involvement of the sarcoidosis with dysfunction of the hypothalamic-pituitary axis with hypogonadotropic hypogonadism and diabetes insipidus due to a sellar mass. CONCLUSION: This is a rare case of systemic sarcoidosis with both thoracic and extra thoracic manifestations, with pituitary and sinus involvement. It shows that sarcoidosis can affect any organ system and diagnosis can be difficult in case of extrapulmonary manifestations.

Systemic diseases can cause heart block owing to the involvement of the myocardium and thereby the conduction system. Younger patients (<60) with heart block should be evaluated for an underlying systemic disease. These disorders are classified into infiltrative, rheumatologic, endocrine, and hereditary neuromuscular degenerative diseases. Cardiac amyloidosis owing to amyloid fibrils and cardiac sarcoidosis owing to noncaseating granulomas can infiltrate the conduction system leading to heart block. Accelerated atherosclerosis, vasculitis, myocarditis, and interstitial inflammation contribute to heart block in rheumatologic disorders. Myotonic, Becker, and Duchenne muscular dystrophies are neuromuscular diseases involving the myocardium skeletal muscles and can cause heart block.

BACKGROUND: Sarcoidosis is a systemic disease that can affect multiple organs. While pulmonary sarcoidosis is most commonly observed, renal sarcoidosis occurs less frequently. We herein report a case of sarcoidosis with an exceptionally rare distribution including renal lesions. CASE PRESENTATION: A 51-year-old Japanese female was referred because of bilateral parotid swelling and renal dysfunction. Computed tomography scan showed the swelling of bilateral kidneys, parotid glands, and uterus. Ga scintigraphy also showed remarkable accumulation in these organs. Renal biopsy and cytological evaluations of parotid gland and uterus were performed and she was diagnosed as sarcoidosis of these organs. Treatment was initiated with prednisolone 40 mg/day and then renal dysfunction subsequently improved. In addition, the swelling of parotid glands and uterus improved and Ga accumulation in each organ had disappeared. CONCLUSION: This is a first case of renal sarcoidosis complicated by parotid glands and uterus lesions. Pathological findings and the reactivity observed in Ga scintigraphy indicated the presence of lesions in these organs.

Cardiac sarcoidosis (CS) is a form of inflammatory cardiomyopathy associated with significant clinical complications such as high-degree atrioventricular block, ventricular tachycardia, and heart failure as well as sudden cardiac death. It is therefore important to provide an expert consensus statement summarizing the role of different available diagnostic tools and emphasizing the importance of a multidisciplinary approach. By integrating clinical information and the results of diagnostic tests, an accurate, validated, and timely diagnosis can be made, while alternative diagnoses can be reasonably excluded. This clinical expert consensus statement reviews the evidence on the management of different CS manifestations and provides advice to practicing clinicians in the field on the role of immunosuppression and the treatment of cardiac complications based on limited published data and the experience of international CS experts. The monitoring and risk stratification of patients with CS is also covered, while controversies and future research needs are explored.

BACKGROUND: Sarcoidosis is a multisystemic inflammatory disease, characterized by the presence of non-caseating, epithelioid granulomas. Glomerular disease in patients with sarcoidosis is rare and membranous nephropathy (MN) is cited as the most common. The association between the two diseases remained unclear. This article reported a case of co-occurrence of sarcoidosis and anti-PLA2R-associated MN, to provide a possible relationship between these two entities. CASE PRESENTATION: A 61-year-old Chinese Han woman with a history of sarcoidosis was admitted to our hospital for nephrotic syndrome. Her sarcoidosis was diagnosed according to the adenopathy observed on the computed tomography scan and the biopsy of lymph nodes. The MN presented with nephrotic syndrome with a PLA2R antibody titer of 357RU/ml, and the final diagnosis was based on a renal biopsy. The patient's sarcoidosis was remitted after treatment with prednisone. One year later MN was diagnosed, and she was treated with prednisone combined with calcineurin inhibitors, based on a full dose of renin-angiotensin system (RAS) inhibitor. The patient's sarcoidosis had been in remission while the MN was recurrent, and her renal function deteriorated to end-stage renal disease 6 years later due to discontinuation of immunosuppression. A genetic test led to the identification of the HLA-DRB1*0301 and HLA-DRB1*150 genes associated with both sarcoidosis and MN, which provides a new possible explanation of the co-occurrence of these two diseases. CONCLUSION: This case suggested for the first time a potential genetic connection between idiopathic MN and sarcoidosis which needs further studies in the future.

Obstructive sleep apnea (OSA) is very prevalent in sarcoidosis patients. Sarcoidosis of the upper respiratory tract may affect upper airway patency and increase the risk of OSA. Weight gain due to steroid use, upper airway myopathy due to steroids and sarcoidosis itself, and interstitial lung disease with decreased upper airway patency are other reasons for the higher OSA prevalence seen in sarcoidosis. Several clinical manifestations such as fatigue, hypersomnolence, cognitive deficits, and pulmonary hypertension are common to both OSA and sarcoidosis. Therefore, early screening and treatment for OSA can improve symptoms and overall patient quality of life.

BACKGROUND: Sarcoidosis is associated with a poor prognosis. There is a lack of data examining the outcomes and readmission rates of sarcoidosis patients with heart failure (SwHF) and without heart failure (SwoHF). We aimed to compare the impact of non-ischemic heart failure on outcomes and readmissions in these two groups. METHODS: The US Nationwide Readmission Database was queried from 2010 to 2019 for SwHF and SwoHF patients identified using the International Classification of Diseases, 9th and 10th Editions. Those with ischemic heart disease were excluded, and both cohorts were propensity matched for age, gender, and Charlson Comorbidity Index (CCI). Clinical characteristics, length of stay, adjusted healthcare-associated costs, 90-day readmission and mortality were analyzed. RESULTS: We identified 97,961 hospitalized patients (median age 63 years, 37.9% male) with a diagnosis of sarcoidosis (35.9% SwHF vs 64.1% SwoHF). On index admission, heart failure patients had higher prevalences of atrioventricular block (3.3% vs 1.4%, P < .0001), ventricular tachycardia (6.5% vs 1.3%, P < .0001), ventricular fibrillation (0.4% vs 0.1%, P < .0001) and atrial fibrillation (22.1% vs 7.5%, P < .0001). SwHF patients were more likely to be readmitted (hazard ratio 1.28, P < .0001), had higher length of hospital stay (5 vs 4 days, P < .0001), adjusted healthcare-associated costs ($9,667.0 vs $9,087.1, P < .0001) and mortality rates on readmission (5.1% vs 3.8%, P < .0001). Predictors of mortality included heart failure, increasing age, male sex, higher CCI, and liver disease. CONCLUSION: SwHF is associated with higher rates of arrhythmia at index admission, as well as greater hospital cost, readmission and mortality rates compared to those without heart failure.
