Abstract
BACKGROUND Miliary sarcoidosis is a rare form of sarcoidosis characterized by numerous miliary-like micronodules dispersed throughout the lungs. It has been documented in less than 1% of all sarcoidosis cases. We first described a rare case of miliary sarcoidosis and then conducted a literature review on the subject. CASE PRESENTATION A 51-year-old male complained about a progressive loss of appetite, significant weight loss, occasional night sweats, and fatigue. After a thorough clinical exploration, a differential diagnosis of miliary lung disease was suspected - miliary tuberculosis, fungal infection, metastatic pulmonary carcinoma, or sarcoidosis. High-resolution chest computed tomography revealed bilateral diffuse micronodules with mediastinal lymphadenopathy. Histopathological analysis of transbronchial bioptic tissue identified non-caseating epithelioid granulomas, while no malignant cells were found. Lung tuberculosis and fungal infections were excluded. The levels of angiotensin-converting enzyme in the blood, as well as serum's and 24-hour urine calcium levels, were elevated. After a multidisciplinary discussion, the diagnosis of miliary pulmonary sarcoidosis was established. The patient was treated with prednisone for a total of 9 months, with full clinical and radiological recovery. Using PubMed, we also conducted a review of the literature on this topic and discovered only a few case reports of patients with miliary sarcoidosis, with just one systematic review accessible. The key findings of studies investigating patients diagnosed with miliary sarcoidosis are tabularly displayed. CONCLUSIONS Miliary sarcoidosis is an uncommon type of pulmonary sarcoidosis that can mimic several entities that manifest as miliary nodules. Most patients require treatment since it can have a significant impact on lung function.

Abstract
We present a unique case of biopsy-proven necrotising sarcoidosis involving the central nervous system in a man in his 40s. The patient presented with a 2-week history of right-sided headache and diplopia. He had right trochlear and abducens nerve palsy, sensory blunting over V1 and V2 segment of right trigeminal sensory nerve and right sensory neural hearing loss. A contrast-enhanced MRI revealed an enhancing dural-based mass lesion in the petroclival area suggestive of probable meningioma. Surgical resection was attempted and intraoperative consultation with frozen section revealed granulomata. So, the lesion was biopsied and surgical intervention was terminated. A diagnosis of necrotising neurosarcoidosis was confirmed on histopathology. He was treated with steroids after excluding other causes of intracranial necrotising granulomas like tuberculosis and he clinically responded favourably. We report one of the very few case reports of histologically proven necrotising sarcoidosis involving the central nervous system mimicking petroclival meningioma.

Abstract
IMPORTANCE Sarcoidosis is an inflammatory granulomatous disease of unknown cause that affects an estimated 2 to 160 people per 100 000 worldwide and can involve virtually any organ. Approximately 10% to 30% of patients with sarcoidosis develop progressive pulmonary disease. OBSERVATION Among patients with pulmonary sarcoidosis, the rate of spontaneous remission without serious sequelae ranges from 10% to 82%. However, lung disease progression occurs in more than 10% of patients and can result in fibrocystic architectural distortion of the lung, which is associated with a mortality rate of 12% to 18% within 5 years. Overall, the mortality rate for sarcoidosis is approximately 7% within a 5-year follow-up period. Worldwide, more than 60% of deaths from sarcoidosis are due to pulmonary involvement; however, more than 70% of deaths from sarcoidosis are due to cardiac involvement in Japan. Up to 70% of patients with advanced pulmonary sarcoidosis develop precapillary pulmonary hypertension, which is associated with a 5-year mortality rate of approximately 40%. Patients with sarcoidosis and precapillary pulmonary hypertension should be treated with therapies such as phosphodiesterase inhibitors and prostacyclin analogues. Although optimal doses of oral glucocorticoids for pulmonary sarcoidosis are unknown, oral prednisone typically starting at a dose of 20 mg/d to 40 mg/d for 2 to 6 weeks is recommended for patients who are symptomatic (cough, dyspnea, and chest pain) and have parenchymal infiltrates and abnormal pulmonary function test results. Oral glucocorticoids can be tapered over 6 to 18 months if symptoms, pulmonary function test results, and radiographs improve. Prolonged use of oral glucocorticoids may be required to control symptoms and stabilize disease. Patients without adequate improvement while receiving a dose of prednisone of 10 mg/d or greater or those with adverse effects due to glucocorticoids may be prescribed immunosuppressive agents, such as methotrexate, azathioprine, or an anti-tumor necrosis factor medication, either alone or with glucocorticoids combined with appropriate microbial prophylaxis for Pneumocystis jiroveci and herpes zoster. Effective treatments are not available for advanced fibrocystic pulmonary disease. CONCLUSIONS AND RELEVANCE Sarcoidosis has a mortality rate of approximately 7% within a 5-year follow-up period. More than 10% of patients with pulmonary sarcoidosis develop progressive disease and more than 60% of deaths are due to advanced pulmonary sarcoidosis. Oral glucocorticoids with or without another immunosuppressive agent are the first-line therapy for symptomatic patients with abnormal pulmonary function test results and lung infiltrates. Patients with sarcoidosis and precapillary pulmonary hypertension should be treated with therapies such as phosphodiesterase inhibitors and prostacyclin analogues.

Abstract
RATIONALE Necrotizing sarcoid granulomatosis (NSG) has recently been termed "sarcoidosis with NSG pattern" for the disease entity representing nodular sarcoidosis with granulomatous pulmonary angiitis. It is characterized by sarcoid-like granulomas, vasculitis, and a variable degree of necrosis. Its rarity and nonspecific clinical symptoms can easily lead to misdiagnosis or delayed diagnosis. PATIENT CONCERNS We report a 67-year-old female with a biopsy-confirmed sarcoidosis with NSG pattern mimicking pulmonary malignancy on initial chest computed tomography scan. DIAGNOSES Sarcoidosis with NSG pattern. INTERVENTIONS The patient underwent video-assisted thoracoscopic surgery with a lung biopsy. No further treatment was performed after the lung biopsy. OUTCOMES Follow-up imaging studies revealed spontaneous regression of the disease after 2 months. LESSONS Awareness of this rare benign disease entity and overlapping radiologic manifestations with pulmonary malignancy or other granulomatous diseases can be helpful for making a precise diagnosis with a better differential diagnosis.

Abstract
Sarcoidosis (SA) is a systemic granulomatous disorder of unknown etiology with lung and mediastinal lymph nodes (LNs) as the main location. T lymphocytes play important role in the formation of granulomas in SA, but still little is known about the role of maturation profile in the development of inflammatory changes. The aim of this study was to determine the CD4+ and CD8+ T cells maturation profile in LNs and in peripheral blood (PB) and its relation to disease severity expressed by diffusing capacity of the lung for carbon monoxide (DLCO). 29 patients with newly pulmonary SA were studied. Flow cytometry was used for cells evaluation in EBUS-TBNA samples. We observed lower median proportion of T lymphocytes, CD4+ T and CD8+ T cells in patients with DLCO< 80% than in patients with normal diffusion (DLCO > 80%). Patients with DLCO < 80% had lower median proportion of effector and higher median proportion of central memory CD4+ and CD8+ T cells than patients with DLCO > 80%. We reported for the first time that LNs CD4+ and CD8+ T cells maturation differs depending on the DLCO value in sarcoidosis. Lymphocytes profiles in LNs may reflect the immune status of patients with SA and can be analysed by flow cytometry of EBUS-TBNA samples.

Abstract
We report a case of a pulmonary necrotizing sarcoid granulomatosis (NSG)-like lesion possibly associated with coinfection of Mycobacterium avium and Propionibacterium acnes. A solitary nodule in the right middle lobe of the lung was notable for coagulative necrosis with aggregates of sarcoid-like epithelioid granulomas. Small arteries were damaged by granulomas. Both M. avium and P. acnes were detected in the lesion. Furthermore, more P. acnes genomes were detected in the granulomas than in the non-lesion lung. These findings blur the pathophysiologic boundaries among NSG, sarcoidosis, and mycobacteriosis, and suggest that NSG needs to be recognized as continuous spectra of sarcoidosis/mycobcteriosis.

Abstract
Sarcoidosis is a multi-systemic, non-caseating granulomatous disorder with an idiopathic aetiology. We report a 58-year-old Malay woman, with underlying type II diabetes mellitus, hypertension and history of stage II pulmonary sarcoidosis presenting with incidental finding of multiple hypodense liver lesions. Her recent contrasted enhanced computed tomography of the abdomen and pelvis demonstrated multiple intra-abdominal lymphadenopathies with evidence of liver and splenic infiltrations. Her ageappropriate malignancy screening was negative while liver biopsy showed non-caseating granulomatous hepatitis consistent with hepatic sarcoidosis. In view of her normal liver enzymes and normalised serum calcium levels, no immunosuppressive therapy was commenced. She remains asymptomatic and is currently under our close monitoring.

Abstract
The sarcoidosis is a systemic granulomatous disease. It is usually characterized by skin manifestations which may be suggestive of progressive sarcoidosis with visceral involvement. We here report a case of pulmonary sarcoidosis revealed by the reactivation of an old cutaneous scar following a trauma occurred 20 years earlier. Radiological assessment showed mediastino-pulmonary sarcoidosis stage 2. The diagnosis of sarcoidosis should be suspected in patients with any recent scar modification in order to establish early management.

Abstract
BACKGROUND Sarcoidosis is a multisystem granulomatous inflammatory disorder, that predominantly involves the lungs. Patients with Löfgren's syndrome (LS) are characterized by acute onset and usually have the HLA-DRB1*03 (DR3positive) allele and a good prognosis. Non-LS patients are usually DR3negative and are more likely to develop chronic disease. The study aimed to identify bronchoalveolar lavage fluid (BALF) cells that could associate with disease severity (reduced pulmonary function tests (PFTs), advanced chest radiographs, need for treatment) and/or chronicity (duration >2 years) in newly diagnosed LS and non-LS patients, respectively. METHODS We retrospectively included data from 955 non-LS patients, 477 LS patients, and 295 healthy controls (HC) in this study. Intra-group comparison of patients with resolving versus chronic disease was performed in LS and non-LS, respectively. Non-LS patients were divided into two subgroups according to the binary BALF cell concentrations for intra-group comparison (i.e. higher or lower than the 95th percentile of the BALF cells references in healthy individuals). RESULTS LS patients with a non-resolving disease course had higher BALF lymphocytes, neutrophils, and eosinophils than LS with a favourable outcome. In non-LS subjects increased BALF of the same cells and in addition also of basophils and mast cells were more likely associated with more severe disease course. CONCLUSION Increased BALF cells display prognostic significance in sarcoidosis. Certain BALF profiles should promote the clinician to monitor these patients more closely as they may associate non-resolving disease, in turn, resulting in future irreversible functional impairment.

Abstract
Pulmonary lesions on imaging are presumed to be metastatic lesions in patients with breast cancer. Here, we report an interesting case of a 63-year-old lady with breast carcinoma showing pulmonary lesions on imaging suggestive of pulmonary metastases. Detailed evaluation of pulmonary lesions confirmed the presence of co-existing pulmonary sarcoidosis. Modern diagnostic methods like 18-flurodeoxyglucose positron emission tomography (18-FDG PET) are unable to clearly differentiate metastatic disease from granulomatous diseases like sarcoidosis. Thus, histological confirmation is needed for accurate staging and determining response to treatment and rarely, in non-responders, detecting any co-existing disease. This case emphasizes the need for detailed histopathological examination of lymph nodes in patients with non-responsive disease or recurrent disease despite adequate chemotherapy.

Abstract
Sarcoidosis is a systemic condition characterized by formation of granulomas that can involve many organ systems, with the lungs and intrathoracic lymph nodes involved in more than 90% of cases. Sarcoidosis also can involve the cardiac, ocular, hepatic, dermatologic, and central nervous systems. The presentation of pulmonary sarcoidosis is nonspecific. Less than half of patients initially have respiratory symptoms and the disease often is detected as an incidental finding of lymphadenopathy on chest x-ray. However, lymphadenopathy can occur in many other conditions, ranging from tuberculosis to cancer, so sarcoidosis should be diagnosed only after excluding these other conditions. Typical granulomatous findings on lymph node biopsy can increase confidence in sarcoidosis diagnosis after the other conditions are excluded. However, there are three syndromes which, if present, are diagnostic of sarcoidosis: Lofgren syndrome, Heerfordt syndrome, and lupus pernio. The majority of sarcoidosis cases resolve spontaneously, so treatment typically is reserved for patients with progressive pulmonary or extrapulmonary involvement, specifically ocular, cardiac, or central nervous system. Systemic corticosteroids are first-line treatment. Second-line treatment with methotrexate or hydroxychloroquine is used if steroids are ineffective or to enable steroid tapering. Refractory disease should be comanaged with a sarcoidosis subspecialist.

Abstract
We herein report a rare case of pulmonary sarcoidosis leading to chronic respiratory failure with restrictive ventilatory impairment during a 53-year-long observation period. Nine years after the histological diagnosis of stage I sarcoidosis on chest X-ray in a woman in her 20s, she developed bilateral reticular and granular opacities on chest computed tomography and was started on prednisone for 18 years. Seven years after prednisone withdrawal, these persisting opacities around the bronchovascular bundle, including a central-peripheral band, had progressed, forming traction bronchiectasis clusters and peripheral cysts, some of which developed continuously at the distal side of these clusters, with eventual upper lobe shrinkage.

Abstract
RATIONALE Despite the availability of multi-"omics" strategies, insights into the etiology and pathogenesis of sarcoidosis have been elusive. This is partly due to the lack of reliable preclinical models and a paucity of validated biomarkers. As granulomas are a key feature of sarcoidosis, we speculate that direct genomic interrogation of sarcoid tissues, may lead to identification of dysregulated gene pathways or biomarker signatures. OBJECTIVE To facilitate the development sarcoidosis genomic biomarkers by gene expression profiling of sarcoidosis granulomas in lung and lymph node tissues (most commonly affected organs) and comparison to infectious granulomas (coccidiodomycosis and tuberculosis). METHODS Transcriptomic profiles of immune-related gene from micro-dissected sarcoidosis granulomas within lung and mediastinal lymph node tissues and compared to infectious granulomas from paraffin-embedded blocks. Differentially-expressed genes (DEGs) were profiled, compared among the three granulomatous diseases and analyzed for functional enrichment pathways. RESULTS Despite histologic similarities, DEGs and pathway enrichment markedly differed in sarcoidosis granulomas from lymph nodes and lung. Lymph nodes showed a clear immunological response, whereas a structural regenerative response was observed in lung. Sarcoidosis granuloma gene expression data corroborated previously reported genomic biomarkers (STAB1, HBEGF, and NOTCH4), excluded others and identified new genomic markers present in lung and lymph nodes, ADAMTS1, NPR1 and CXCL2. Comparisons between sarcoidosis and pathogen granulomas identified pathway divergences and commonalities at gene expression level. CONCLUSION These findings suggest the importance of tissue and disease-specificity evaluation when exploring sarcoidosis genomic markers. This relevant translational information in sarcoidosis and other two histopathological similar infections provides meaningful specific genomic-derived biomarkers for sarcoidosis diagnosis and prognosis.

Abstract
BACKGROUND Some patients with sarcoidosis experience worsening of pulmonary lesions. However, no biomarker has been identified that reflects pulmonary disease status in sarcoidosis. We investigated the usefulness of potential markers of pulmonary fibrosis in patients with sarcoidosis. METHODS Plasma matrix metalloproteinase 7 (MMP-7), CC-chemokine ligand 18 (CCL-18), and periostin levels were evaluated in 60 patients with sarcoidosis and 30 healthy controls; bronchoalveolar lavage fluid levels were analyzed in 22 patients with sarcoidosis. To determine the usefulness of these markers, we explored potential correlations between these markers and sarcoidosis clinical characteristics. RESULTS Plasma MMP-7, CCL-18, and periostin concentrations were significantly higher in patients with sarcoidosis than those in healthy controls. MMP-7 concentrations in plasma and bronchoalveolar lavage fluid were higher in patients with sarcoidosis with parenchymal infiltration than in those without lung lesions. Moreover, MMP-7 concentration was negatively correlated with pulmonary function. CONCLUSION Among these novel biomarkers, MMP-7 most precisely reflected pulmonary sarcoidosis disease status and thus, might be useful for diagnosing and evaluating sarcoidosis, particularly in patients with pulmonary parenchymal lesions.

Abstract
Sarcoidosis is a rare disease characterized by granulomatous inflammation in affected organs, primarily in lungs. Neutrophil/lymphocyte ratio (NLR) and platelet/lymphocyte ratio (PLR) are easy and practical methods providing valuable information in diagnosis, severity, and prognosis of various diseases. Here, we aimed to investigate the association between NLR, PLR, and hematological parameters in sarcoidosis. The study was performed with 75 sarcoidosis patients and 92 controls. Patients' NLR, PLR, and hematological parameters were compared with those of controls. Additionally, while differences between NLR and PLR were investigated in sarcoidosis patients, differences of extrapulmonary involvement, pulmonary hypertension (PH), and spontaneous remission between those with and without responses to treatment concerning stages were also assessed. NLR and PLR were significantly higher in sarcoidosis patients than controls. For NLR, sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were found as 68, 61, 58, and 70% respectively, while sensitivity, specificity, PPV, and NPV for PLR were found as 72, 67, 63, and 74%, respectively. In sarcoidosis patients, NLR and PLR were significantly higher at stage-2 and -3 than at stage -1 and -4. There was a significant weak positive correlation between C-reactive protein (CRP) and NLR and PLR. Mean platelet volume (MPV), hemoglobin (Hgb), and mean corpuscular volume (MCV) were lower among patients than controls. A positive moderate correlation was detected between NLR and CD4/CD8 in blood, while there was a strong positive correlation between CD4/CD8 in bronchoalveolar lavage (BAL) and positive moderate correlation between PLR and CD4/CD8 in BAL. High NLR and PLR values were not significantly associated with pulmonary PH, spontaneous remission, response to treatment, and prognosis. The increase in PLR and NLR may be a guide for diagnoses of both sarcoidosis and lung parenchymal involvement. To use these entities as markers, our findings should be supported with prospective studies with larger samples.

Abstract
Sarcoidosis is a multisystem granulomatous disease of unknown etiology and is pathologically characterized by non-caseating granulomas in the organs involved. We herein report a case of sarcoidosis in a Japanese woman with acute respiratory failure, diagnosed using endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) on the ventilator after intubation. Only a few cases of previously undiagnosed sarcoidosis presenting acute respiratory failure have been reported. It is important to be aware that undiagnosed sarcoidosis may present with acute respiratory failure. Therefore, EBUS-TBNA under mechanical ventilation may be useful for the immediate diagnosis of patients.

Abstract
Purpose To investigate whether sarcoidosis patients infected with SARS-CoV-2 are at risk for adverse disease outcomes. Study Design and Methods This retrospective study was conducted in five hospitals within the Mount Sinai Health System during March 1, 2020 to July 29, 2020. All patients diagnosed with COVID-19 were included in the study. We identified sarcoidosis patients who met diagnostic criteria for sarcoidosis according to accepted guidelines. An adverse disease outcome was defined as the presence of intubation and mechanical ventilation or in-hospital mortality. In sarcoidosis patients, we reported (when available) the results of pulmonary function testing measured within 3 years prior to the time of SARS‑CoV‑2 infection. A multivariable logistic regression model was used to generate an adjusted odds ratio (aOR) to evaluate sarcoidosis as a risk factor for an adverse outcome. The same model was used to analyze sarcoidosis patients with moderate and/or severe impairment in pulmonary function. Results The study included 7337 patients, 37 of whom (0.5%) had sarcoidosis. The crude rate of developing an adverse outcome was significantly higher in patients with moderately and/or severely impaired pulmonary function (9/14 vs. 3/23, p = 0.003). While the diagnosis of sarcoidosis was not independently associated with risk of an adverse event, (aOR 1.8, 95% CI 0.9–3.6), the diagnosis of sarcoidosis in patients with moderately and/or severely impaired pulmonary function was associated with an adverse outcome (aOR 7.8, 95% CI 2.4–25.8). Conclusion Moderate or severe impairment in pulmonary function is associated with mortality in sarcoidosis patients infected with SARS‑CoV‑2.

Abstract
Background: The diagnosis of sarcoidosis is not standardized but is based on three major criteria: a compatible clinical presentation, finding nonnecrotizing granulomatous inflammation in one or more tissue samples, and the exclusion of alternative causes of granulomatous disease. There are no universally accepted measures to determine if each diagnostic criterion has been satisfied; therefore, the diagnosis of sarcoidosis is never fully secure. Methods: Systematic reviews and, when appropriate, meta-analyses were performed to summarize the best available evidence. The evidence was appraised using the Grading of Recommendations, Assessment, Development, and Evaluation approach and then discussed by a multidisciplinary panel. Recommendations for or against various diagnostic tests were formulated and graded after the expert panel weighed desirable and undesirable consequences, certainty of estimates, feasibility, and acceptability. Results: The clinical presentation, histopathology, and exclusion of alternative diagnoses were summarized. On the basis of the available evidence, the expert committee made 1 strong recommendation for baseline serum calcium testing, 13 conditional recommendations, and 1 best practice statement. All evidence was very low quality. Conclusions: The panel used systematic reviews of the evidence to inform clinical recommendations in favor of or against various diagnostic tests in patients with suspected or known sarcoidosis. The evidence and recommendations should be revisited as new evidence becomes available.

Abstract
OBJECTIVE To evaluate the clinical characteristics and outcomes of patients with asymptomatic pulmonary sarcoidosis (APS) detected incidentally and compare them with symptomatic non-Löfgren sarcoidosis (SnLS) patients. METHODS Patients diagnosed as having APS at a University hospital in Barcelona, Spain, followed prospectively from 1976 to 2018. APS was defined as the presence of bilateral hilar lymphadenopathy (BHL) with or without lung parenchymal involvement discovered incidentally on chest radiograph or CT scan. APS was compared with SnLS. RESULTS APS was diagnosed in 50 (13.6%) and SnLS in 317 (86.4%) patients. At diagnosis, stage I chest radiograph was significantly more frequent in APS than in SnLS (p < 0.001) and there were no asymptomatic patients with stages III and IV. SnLS showed more severe impairment in FVC (p = 0.009) and forced expiratory volume in 1st second (FEV1) (p = 0.003) than APS, while DLco was similar in both groups. Extrathoracic involvement at diagnosis and during the follow up was less frequent in APS than in SnLS patients (p < 0.005). Endobronchial ultrasonography-guided transbronchial needle aspiration (EBUS) was the most used diagnostic tool. Treatment was more frequently required in the SnLS than in APS (p < 0.001). At five years, APS patients showed less presence of active disease than SnLS (p = 0.054). CONCLUSIONS APS showed earlier radiological stages, lesser impairment in lung function, extrapulmonary organ involvement and need for treatment than SnLS. EBUS was the most useful diagnostic tool. In spite of its benign presentation, around one third of patients evolved to persistent disease but usually with mild clinical and functional impairment.

Abstract
Sarcoidosis is a disorder characterized by granulomatous inflammation of unclear etiology. In this study we evaluated whether veterans with sarcoidosis exhibited different plasma metabolomic and metallomic profiles compared with civilians with sarcoidosis. A case control study was performed on veteran and civilian patients with confirmed sarcoidosis. Proton nuclear magnetic resonance spectroscopy (1H NMR), hydrophilic interaction liquid chromatography mass spectrometry (HILIC-MS) and inductively coupled plasma mass spectrometry (ICP-MS) were applied to quantify metabolites and metal elements in plasma samples. Our results revealed that the veterans with sarcoidosis significantly differed from civilians, according to metabolic and metallomics profiles. Moreover, the results showed that veterans with sarcoidosis and veterans with COPD were similar to each other in metabolomics and metallomics profiles. This study suggests the important role of environmental risk factors in the development of different molecular phenotypic responses of sarcoidosis. In addition, this study suggests that sarcoidosis in veterans may be an occupational disease.

Abstract
Sarcoidosis is a highly variable granulomatous multisystem syndrome. It affects individuals in the prime years of life; both the frequency and severity of sarcoidosis are greater in economically disadvantaged populations. The diagnosis, assessment, and management of pulmonary sarcoidosis have evolved as new technologies and therapies have been adopted. Transbronchial needle aspiration guided by endobronchial ultrasound has replaced mediastinoscopy in many centers. Advanced imaging modalities, such as fluorodeoxyglucose positron emission tomography scanning, and the widespread availability of magnetic resonance imaging have led to more sensitive assessment of organ involvement and disease activity. Although several new insights about the pathogenesis of sarcoidosis exist, no new therapies have been specifically developed for use in the disease. The current or proposed use of immunosuppressive medications for sarcoidosis has been extrapolated from other disease states; various novel pathways are currently under investigation as therapeutic targets. Coupled with the growing recognition of corticosteroid toxicities for managing sarcoidosis, the use of corticosteroid sparing anti-sarcoidosis medications is likely to increase. Besides treatment of granulomatous inflammation, recognition and management of the non-granulomatous complications of pulmonary sarcoidosis are needed for optimal outcomes in patients with advanced disease.
