The role of chest X-ray in the early diagnosis and staging of sarcoidosis: Is it really should be done?

BACKGROUND: Sarcoidosis is a chronic granulomatous disease characterized by non-caseating granuloma. The conventional chest X-ray (CXR) has important role in the diagnosis, staging and follow-up of disease. Computed tomography (CT) is a second-line imaging method used to determine the extent, complications and differential diagnosis of sarcoidosis. OBJECTIVES: To determine the role of CXR in the early diagnosis and staging of sarcoidosis and to compare with CT imaging. METHODS: One hundred and nine sarcoidosis patients followed at a single center were included in the study. Demographic, radiological, and clinical data of 81 patients were obtained from a total of 109 patients, and the record data of these 81 patients were evaluated. Patients who could not be reached for all tests were excluded from the study. CXR and CT imaging taken at diagnosis were evaluated retrospectively independently from two radiologists and one rheumatologist. RESULTS: Among 109 patients, eighty-one patients CXR and CT imaging taken at the same center has been reached. Among 81 sarcoidosis patients 23 (28.4%) were male, 58 (71.6%) were female. The mean patients age was 46.4 years and the mean disease duration was 3.8 years. CXR is regarded as normal at diagnosis in 30 patients (37%), while all of these patients had findings consistent with sarcoidosis on CT imaging. CT imaging are more superior than CXR in the early diagnosis and staging of sarcoidosis (p=0.001). Also CT imaging is more superior for detection of disease extent and complications. CONCLUSIONS: In this study, we observed that CT imaging outperforms CXR in terms of early detection and staging of sarcoidosis. The use of CT imaging is important for early diagnosis and staging of sarcoidosis. The low performance of CXR is a condition that requires the discussion of this method. Multicenter prospective study is needed in this regard.

SARS-CoV-2 Infection-Induced Necrotising Sarcoid Granulomatosis.

SARS-CoV-2 infection is a pandemic that affects predominantly upper airways and lungs. It may lead to reactivation of known inflammatory rheumatic diseases and/or initiation of various granulomatous disorders. Necrotising sarcoid granulomatosis (NSG) is a rare condition that can be confused with malignancy, granulomatosis with polyangiitis, and sarcoidosis. Herein we reported the development of NSG following a SARS-CoV-2 infection which mimicked granulomatosis with polyangiitis.

Increased circulating interleukin-23 level in patients with sarcoidosis.

BACKGROUND: Sarcoidosis is a Th1-mediated chronic inflammatory disease characterized by non-caseating granulomas. Its pathogenesis is not yet clear, but the possible role of various proinflammatory cytokines is being discussed. AIM: This study aims to determine serum cytokine (IL-6, IL-12, IL-17, and IL-23) levels in patients with sarcoidosis, and to determine a possible correlation with clinical and laboratory findings of the disease. MATERIAL AND METHOD: Forty-four biopsy-proven sarcoidosis patients followed up at a single centre and 41 healthy volunteers were included in the study. Demographic, clinical, laboratory, and radiological data of all patients were recorded. Serum samples from the patients and the control group were taken and IL-6, IL-12, IL-17, IL-23 were measured by ELISA method. RESULTS: Of the 44 sarcoidosis patients, 13(29.5%) were male and 31(70.5%) were female. Average patient age was 47.4 years, mean disease duration was 3.2 years. Twenty-one (47.7%) patients had erythema nodosum, three (6.8%) had uveitis, 40(90.9%) had arthralgia, 23(52.3%) had ankle arthritis, 15(34.1%) had enthesitis. Laboratory evaluation showed increased serum ACE levels in 24(54.5%) patients, increased serum calcium levels in 11 (25%) patients, increased serum D3 levels in 5(11.4%) patients, increased ESR and CRP levels in 22(50%) and 23(52.3%) patients, respectively. Compared with the control group higher serum IL-23 levels were found in the patients with sarcoidosis (p=.01). Serum IL-23 was associated with ankle arthritis (p=.02). Serum IL-6, IL-12, and IL-17 levels were similar in the sarcoidosis patients and the control group (p=.128, p=.212, p=.521 respectively). CONCLUSION: In our study, we found increased serum IL-23 in patients with sarcoidosis, while serum IL-6, IL-12, and IL-17 were detected as normal. Although our results are somewhat contradictory to other studies in the literature, the question should still be whether sarcoidosis is a Th1/Th17 disease. Multicentre studies are needed in this regard.

Atezolizumab Lung Toxicity and Importance of Combination Treatment: A Case Report.

BACKGROUND: Lung cancer is one of the most common and mortal cancers worldwide. According to pathological and clinical groups, treatments vary, and a tailored approach is considered. Adjuvant therapies, such as chemotherapy, radiation, and immune checkpoint inhibitors (ICI), are recommended by recent guidelines for patients with locally advanced cancer. OBJECTIVE: This study aimed to report the case of a patient with stage 2B squamous cell lung carcinoma who was managed for pulmonary toxicity after receiving adjuvant chemotherapy and atezolizumab treatment. CASE REPORT: A 66-year-old male patient received chemotherapy and immunotherapy after surgery for squamous cell lung cancer. A diagnosis of atezolizumab-associated pneumonitis was made using laboratory tests and imaging due to the patient's worsening dyspnea after treatment. Due to the patient's rapid progression, pulse steroid and MMF therapy were administered concurrently. When Klebsiella pneumoniae growth was detected in the sputum culture during the follow-up, IVIg was used to supplement the medication. The patient showed significant clinical and radiological improvement. CONCLUSION: In this study, we present an atezolizumab-induced pneumonitis case of a squamous cell lung cancer patient. It may be life-saving not to avoid aggressive treatment approaches by combining the steps of guideline recommendations in patients with rapidly progressive pneumonitis.

Treat to target and tight control: Could be a new approach in the treatment of sarcoidosis?

Sarcoidosis is a chronic granulomatous disease with multisystemic involvement. Although it is accepted as a benign disease, it can sometimes cause life-threatening organ (heart, brain) involvement that determines the prognosis of the disease. There are conflicting opinions about the treatment of the disease. In the generally accepted treatment approach the "step-by-step" model has gained weight. According to this approach, corticosteroids (CS) drugs alone are preferred in the first step in patients who require treatment. In the second step, immunosuppressive drugs (IS) are used in patients who do not respond to CS and/or have contraindications to CS use, and biologics (TNF-alpha inhibitors) are used in the third step. This treatment approach may be valid in cases with mild sarcoidosis. However, although sarcoidosis is considered a benign and self-limiting disease in some major organ involvement, the "step-by-step" approach may be a treatment option that puts the patient's life in danger. In such selected patients, much more rigorous, early and combined treatment approaches that definitely include CS, IS or biologic drugs may be required. In selected sarcoidosis patients with high risk, early diagnosis, "treat-to-target" (T2T) and "tight control" follow-up of patients seems to be a rational approach. This article reviews the "step-down" treatment regimens in light of recent literature data and hypothesizes that the T2T model may be a probable new treatment approach in patients with sarcoidosis.

Serum salusin-α and salusin-ß levels in patients with psoriatic arthritis.

Introduction: Psoriatic arthritis (PsA) is a chronic inflammatory disease characterized by skin lesions and joint involvement. Salusin-α and salusin-ß are two new bioactive molecules. It is reported that salusins may have role in regulation of the immune system and inflammation. The aim of our study was to evaluate the serum salusin-α and salusin-ß levels in PsA patients and to establish the possible relationship with the disease features. Material and methods: Our study included 40 PsA patients who fulfilled the CASPAR criteria and 40 healthy volunteers. Demographic, clinical, laboratory and radiological data and disease activity indices (PASI, BASDAI, BASFI, HAQ) were recorded in all patients. The enzyme-linked immunosorbent assay (ELISA) method was used to measure serum salusin-α and salusin-ß levels. Results: The demographic data were as follows: 13 patients (32.5%) were males and 27 (67.5%) were female, mean age was 48.5 years and mean disease duration was 2.4 years. Patients' history was taken and clinical assessment was performed; 20 (50%) patients had a family history, 18 (45%) patients were smoker, 19 (47.5%) patients had HLA-B27 positivity, 33 (82.5%) had sacroiliitis, 36 (90%) had enthesitis, 23 (57.5%) had distal interphalangeal (DIP) joint and nail involvement, 26 (65%) had wrist involvement, and 11 (27.5%) had ankle involvement. Laboratory data of the patients were recorded; 20 (50%) patients had elevated CRP level and 25 (62.5%) patients had an elevated ESR level. The study results showed that PsA patients had an elevated serum salusin-α level when compared with the control group (p = 0.004). The association between serum salusin-α level and ankle arthritis was found (p = 0.04). Serum levels of salusin-ß were similar in PsA patients and controls both (p = 0.285). Conclusions: We found elevated serum salusin-α in PsA patients while the serum salusin-ß levels were normal. Salusin-α may have a possible role in disease pathogenesis and it may be use as a reliable biomarker in PsA patients. Multicenter prospective studies are needed in this regard.

Serum galectin-3 and TGF-beta levels in patients with sarcoidosis.

INTRODUCTION: Sarcoidosis is a chronic granulomatous disease that develops with non-caseified granuloma formation. Galectin-3 is a multifunctional protein operating in biological processes such as fibrosis, angiogenesis, and immune activation. PURPOSE: This study evaluates the levels of serum galectin-3 and TGF-beta in sarcoidosis patients to determine a possible correlation with clinical findings. MATERIAL AND METHOD: Forty-four biopsy-proven sarcoidosis patients followed in a single centre and 41 age and sex-matched healthy volunteers were included in the study. The levels of serum galectin-3 and TGF-beta were evaluated by ELISA method. RESULTS: Among the 44 sarcoidosis patients, 13(29.5%) were male and 31(70.5%) were female. The average patient age was 47.4 and the average disease duration was 3.2 years. The level of serum galectin-3 was found to be the same as in the control group and had no significance statistically (p=.977). No correlation was determined between the level of serum galectin-3 and clinical and laboratory findings of sarcoidosis (p>.05). The level of serum TGF-beta was found to be higher in the sarcoidosis patients when compared to that of the control group (p=.005). While a correlation was found between serum TGF-beta and enthesitis, sacroiliitis, and arthralgia (p=.006, p=.034, p=.02), no correlation was determined on the other clinical and laboratory findings (p>.05). CONCLUSION: While the level of serum galectin-3 was determined to be normal in sarcoidosis patients, a high level of serum TGF-beta was found. These findings show that TGF-beta may play an important role in sarcoidosis pathogenesis and the formation of granuloma.

Ustekinumab-induced chronic lymphocytic leukemia in a patient with psoriatic arthritis.

Psoriatic arthritis (PsA) is a chronic inflammatory disease characterized by skin and joint involvement. The disease may present with various joint pattern involvement, which sometimes may lead to joint destruction and deformity. Early diagnosis and treatment with disease-modifying anti-rheumatic drugs may prevent joint deformity. Recently there are many new treatment options including biologic drugs. Ustekinumab, an interleukin 12/23 inhibitor, has proven efficacy in the treatment of psoriatic arthritis. Like other biologic drugs (anti-TNF-α), there are contradictory data about the safety of ustekinumab and possible relationship with cancer development. Herein we report the development of chronic lymphocytic leukemia in a patient with PsA treated with ustekinumab.

Malignancy in patients with sarcoidosis.

The relationship between sarcoidosis and malignancy is not clear yet. We retrospectively evaluated 131 sarcoidosis patients followed-up at the single Rheumatology center. The incidence of malignancies was investigated in this cohort. A total of 6 (4.6%) patients with malignancy were identified in our cohort of 131 patients with sarcoidosis. Hodgkin lymphoma (HL) was detected in three patients, followed by one patient with breast cancer, one patient with thyroid cancer and one patient with testicular cancer. All patients had chronic sarcoidosis with pulmonary involvement, and only 1 patient had acute sarcoidosis with Löfgren's syndrome. HL developed concomitantly with sarcoidosis in one patient while other two patients developed disease before and after sarcoidosis diagnosis. Two patients with solid tumors developed malignancy years before sarcoidosis diagnosis, while one patient developed thyroid cancer during sarcoidosis follow-up. All 6 sarcoidosis-malignancy patients survived after six year years follow up. We found low incidence of malignancy in patients with sarcoidosis in our small cohort. The sarcoidosis-malignancy relationship can only be a coincidence and/or can be explained by a common pathogenesis. New prospective studies involving large patients series are needed in this regard.

Serum Galectin-3 and TGF-Beta Levels in Patients With Sarcoidosis.

INTRODUCTION: Sarcoidosis is a chronic granulomatous disease that develops with non-caseified granuloma formation. Galectin-3 is a multifunctional protein operating in biological processes such as fibrosis, angiogenesis, and immune activation. PURPOSE: This study evaluates the levels of serum galectin-3 and TGF-beta in sarcoidosis patients to determine a possible correlation with clinical findings. MATERIAL AND METHOD: Forty-four biopsy-proven sarcoidosis patients followed in a single centre and 41 age and sex-matched healthy volunteers were included in the study. The levels of serum galectin-3 and TGF-beta were evaluated by ELISA method. RESULTS: Among the 44 sarcoidosis patients, 13(29.5%) were male and 31(70.5%) were female. The average patient age was 47.4 and the average disease duration was 3.2 years. The level of serum galectin-3 was found to be the same as in the control group and had no significance statistically (p=.977). No correlation was determined between the level of serum galectin-3 and clinical and laboratory findings of sarcoidosis (p>.05). The level of serum TGF-beta was found to be higher in the sarcoidosis patients when compared to that of the control group (p=.005). While a correlation was found between serum TGF-beta and enthesitis, sacroiliitis, and arthralgia (p=.006, p=.034, p=.02), no correlation was determined on the other clinical and laboratory findings (p>.05). CONCLUSION: While the level of serum galectin-3 was determined to be normal in sarcoidosis patients, a high level of serum TGF-beta was found. These findings show that TGF-beta may play an important role in sarcoidosis pathogenesis and the formation of granuloma.

Catch the rainbow: Prognostic factor of sarcoidosis.

Sarcoidosis is a systemic, chronic, inflammatory disease characterized by noncaseating granuloma formations. The fact that the etiopathogenesis of the disease has not been elucidated yet brings it many theories and assumptions. Being a systemic disease and ability to involve many organs and systems, it attracts the attention of physicians from different branches. In addition to lung involvement, skin, eye, heart, and locomotor system involvement is an important clinical finding. Sarcoidosis may present with very different clinical presentations, and therefore, it is one of the important "imitators" in the medical literature. I like sarcoidosis as a "rainbow," it is a disease that contains the characteristics of many diseases. Different clinical, radiological, and laboratory prognostic factors (lupus pernio, chronic uveitis, late-onset disease, chronic hypercalcemia, nephrocalcinosis, Afro-American race, progressive pulmonary sarcoidosis, radiologic Stage 4, bone involvement, neurosarcoidosis, cardiac involvement, and chronic respiratory failure) have been defined in this "rainbow." Early identification of these factors plays an important role in the determination of treatment strategies, morbidity, and mortality of the disease. In this article, clinical, genetic, laboratory, and radiological factors that determine the prognosis of sarcoidosis are discussed in light of the latest data in the literature.

Ustekinumab-induced Sarcoidosis in a Patient with Psoriatic Arthritis.

BACKGROUND: Psoriatic Arthritis (PsA) is a chronic inflammatory disease that may affect different joints. Sarcoidosis is a Th-1 cell-related chronic granulomatous disease characterized by non-caseating granuloma formation. The coexistence of both the diseases is a rare entity. Ustekinumab, an IL12 / 23 inhibitor, has shown efficacy and safety in the treatment of PsA. OBJECTIVE: This study presents a case with ustekinumab-induced sarcoidosis in a patient with PsA. CASE REPORT: A 52 years old female patient with complaints of pain and swelling of the wrists, MCP, PIP and DIP joints and skin lesions was referred to our Rheumatology clinic. On her medical history, she had been under follow up for 5 years with the diagnosis of psoriasis and one year ago, she started to receive ustekinumab prescribed by a dermatologist. On physical examination, she had psoriasis skin lesions and arthritis of both wrists, MCP, PIP, DIP joints. Bilateral hilar lymphadenopathies were detected in the chest X-ray and thorax computed tomography. In laboratory tests, acute phase reactants and serum angiotensin-converting enzyme levels were high. Endobronchial ultrasonography biopsy was performed and non-caseating granuloma consistent with sarcoidosis was reported. Ustekinumab was discontinued, methotrexate and low-dose corticosteroid were started. The patient was clinically stable in the 6th month of the treatment and the findings were regressed. CONCLUSION: Sarcoidosis development appears to be a new paradoxical effect of ustekinumab therapy, being another biological agent.

Serum adipokine levels in patients with sarcoidosis.

BACKGROUND: Sarcoidosis is a chronic inflammatory disease characterized by non-caseating granuloma which etiology is unknown yet. Adipokines are different proteins synthesized by adipose tissue that have an influence on angiogenesis, hemostasis, lipid metabolism, and immune system regulation. Adipokines may play a role in the pathogenesis of sarcoidosis. OBJECTIVES: To evaluate the serum adipokine levels in patients with sarcoidosis and to determine a possible correlation with clinical and laboratory signs of disease. METHODS: Forty-four biopsy-proven sarcoidosis patients followed at a single center and age- and sex-matched 41 healthy volunteers were included in the study. Demographic, clinical, laboratory, and radiological data were recorded and body mass index (BMI) was calculated in all patients. Routine laboratory tests (blood glucose, liver, and kidney function test) were measured. Serum adiponectin and leptin levels were measured by ELISA method. RESULTS: Among 44sarcoidosis patients, 13 (29.5%) were male and 31 (70.5%) were female. Twenty-one (47.7%) patients had erythema nodosum, three (6.8%) had uveitis, 40 (90.9%) had arthralgia, 32 (72.7%) had arthritis, 15 (34.1%) had enthesitis. Laboratory evaluation showed increased serum ACE level in 24 (54.5%) patients, increased serum calcium level in 11 (25%) patients, increased serum D3 level in 5 (11.4%) patients, and increased ESR and CRP levels in 22 (50%) and 23 (52.3%) patients, respectively. Compared with the control group, serum adiponectin levels were significantly higher in patients with sarcoidosis(p = 0.007). Serum adiponectin level was associated with arthralgia and ankle joint swelling (p = 0.007, p = 0.006 respectively). Serum leptin levels were similar in sarcoidosis patients and controls (p = 0.327). There was no relationship between serum leptin level and disease features (p > 0.05). CONCLUSIONS: In this study, high serum adiponectin level was detected in patients with sarcoidosis while serum leptin level was similar in the sarcoidosis and control group. Adiponectin, an anti-inflammatory protein, may play a role in the pathogenesis of sarcoidosis. Studies are needed to shed light on this topic.Key Points• Sarcoidosis is a chronic granulomatous disease characterized by granuloma formation• High serum adiponectin level was found in sarcoidosis patients• Serum adiponectin level was associated with some clinical features such as arthralgia and arthritis• High adiponectin levels in sarcoidosis patients may mitigate the inflammatory response, resulting in a mild form of the disease and/or spontaneous remission.

Regression of Sarcoidosis during Pregnancy: Case Report and Review of the Literature.

Sarcoidosis is a chronic granulomatous disease characterized by non-caseating granuloma formation. It usually involves the lung, but may also affects many organs and systems such as the musculoskeletal system, eye, skin, and heart. The data on the course of sarcoidosis during pregnancy are controversial. Generally, sarcoidosis patients do not have a decrease in fertility, and there is no increase in the incidence of congenital abnormalities or premature birth. On the other hand, sarcoidosis may progress during pregnancy. In this report, we discussed the effects of pregnancy on the disease activity in a patient with sarcoidosis.

Pembrolizumab-Induced Seronegative Arthritis and Fasciitis in a Patient with Lung Adenocarcinoma.

BACKGROUND: Immune checkpoint inhibitors (CPIs) are new promising anti-cancer drugs that block negative costimulation of T-cells leading to an enhanced anti-tumor immune response. Pembrolizumab, an a monoclonal antibody, targeting the programmed cell death protein 1 (PD-1) pathway. CPIs have been associated with a number of immune-related adverse events (AEs), including musculoskeletal and rheumatic disease. OBJECTIVE: To present a case with lung adenocarcinoma treated with pembrolizumab, which developed inflammatory arthritis and fasciitis. CASE REPORT: A 73-year-old male patient was referred to the rheumatology outpatient clinic with complaints of pain in the pretibial area, pain and swelling in both ankles joints and the right first metacarpophalangeal (MCP) joint. Three months ago he had diagnosed with lung adenocarcinoma and pembrolizumab was started. Locomotor system complaints were started after receiving two infusions of pembrolizumab. Physical examination revealed both ankle arthritis, mild edema in the pretibial region, tenderness in the muscles and arthritis in the right first MCP joint. Laboratory examinations showed mild acute phase reactants elevation. Lower extremity MRI showed diffuse edema in both gastrocnemius muscle and fascia, compatible with fasciitis. Pembrolizumab-related fasciitis and seronegative arthritis were diagnosed. Low dose corticosteroid was started and a significant regression was observed in the patient's complaints. CONCLUSION: Inflammatory myositis with fasciitis and inflammatory arthritis in lower extremities appears to be a new adverse effect of pembrolizumab therapy.

Immune Checkpoint Inhibitors-related Rheumatic Diseases: What Rheumatologist Should Know?

Immune checkpoint inhibitors are revolutionized drugs for cancer immunotherapy in the last years. The mechanism of action of CPIs including the limitation of the activation of Tcells, and thus enhancing the self-immune response against tumour cells. Checkpointinhibitors( CPIs) may dysregulate the immune system, resulting in some toxicities. These toxicities or side effects are called Immune-related Adverse Events (IRAEs) that can potentially affect any organ and tissue. Rheumatic diseases due to checkpoint inhibitors are also reported in the literature. The spectrum of rheumatic manifestations are quite wide; the most common are arthralgia/arthritis, myalgia/myositis, polimyalgia rheumatica, lupus, rheumatoid arthritis, Sjögren's syndrome. At the same time, these drugs can also cause an exacerbation of known rheumatologic disease. Treatment approaches for developing rheumatic findings due to checkpoint inhibitors should be multidisciplinary. There should be a close relationship between oncologists who follow-up these patients and rheumatologists. The rheumatic manifestations should be defined and treated early. In general, the musculoskeletal side effects are transient and may regress after stopping CPIs. The most commonly used medications are corticosteroids. Immunosuppressive drugs (HQ, MTX, anti-TNF-alpha, anti-IL-6) should be preferred when treatment is unresponsive or as steroid-sparing agents. The aim of this review was to evaluate the checkpoint inhibitors-related rheumatologic findings and therapeutic strategies in light of recent literature data.

Coexistence of Sarcoidosis and Gouty Arthritis.

Sarcoidosis is an inflammatory disease with unknown cause characterized by non-caseating granuloma formations. It may present with bilateral hilar lymphadenopathy, skin lesions, the involvement of eye and symptoms on the locomotor system. Gouty arthritis is an autoinflammatory disease characterized by hyperuricemia, recurrent arthritis attacks and the deposition of monosodium urate crystals in the joints and the surrounding tissues. We reported the coexistence of sarcoidosis and gouty arthritis in this paper.

Coexistence of sarcoidosis and adult onset Still disease.

Sarcoidosis is a chronic, inflammatory disease with unknown cause characterized by non-caseating granuloma formations. It can be presented with bilateral hilar lymphadenopathy, skin lesions, eye involvement and locomotor system findings. Adult onset Still disease (AOSD) is a chronic inflammatory disease which presents with fever, arthritis and typical skin rashes. The disease is rare and can be misdiagnosed due to the absence of typical clinical and laboratory findings. The association of sarcoidosis and AOSD has not been previously reported in the literature. Herein we reported the development of AOSD in a patient followed by the diagnosis of sarcoidosis. The patient did not respond to high-dose corticosteroids and methotrexate therapy, and the disease was under control with anti-IL-6 (Tocilizumab) drug.

Characteristics of Turkish patients with elderly onset psoriatic arthritis: A retrospective cohort study.

Psoriatic arthritis (PsA) is a chronic inflamatory disease characterized with axial and peripheral joints involvement. It rarely affects patients older than 65 years old.The purpose of this study is to compare and evaluate the demographic, clinical and laboratory features of elderly-onset psoriatic arthritis (EOPsA) and young-onset (YOPsA) patients.A total of 180 patients diagnosed with PsA according to CASPAR criteria and followed-up in single center were included in this study. The patients with initial symptoms started after age 65 were accepted as EOPsA. Demographic, clinic, and laboratory data and the medications which the patients received were recorded and retrospectively evaluated.Nineteen (10.5%) of 180 patients were diagnosed as EOPsA, and 161 (89.5%) patients were evaluated as YOPsA. The mean patient age was 42.1years for the YOPsA group and 68.3 years for the elderly onset group. Mean duration of disease was 5.6 years for the early onset group and 1.3 years for the elderly onset group (P = .001). Fourteen (73.3%) of 19 EOPsA patients were female and 5 of them were male. Higher rates of fatique, pain scores, comorbid diseases, and acute phase reactants elevation were detected in EOPsA patients comparing to YOPsA (P = .000, P = .000, P = .001, and P = .001, respectively). YOPsA patients have more dactilitis, nail involvement, elevated PASI scores, and smoking habitus when compared with EOPsA patients (P = .019, P = .03, P = .005, P = .004, respectively). In terms of the treatment options chosen, there was no significant difference in the use of nonsteroidal anti-inflammatory drugs (NSAIDs), corticosteroids (CS), methotrexate (MTX), and sulfasalazine (SSL), but there was a more frequent use of anti-tumor necrosis factor-alpha in the YOPsA group.YOPsA and EOPsA patients may presented with different clinical and laboratory features. EOPsA patients are characterized with higher rates of fatigue, pain scores, comorbid diseases, and acute phase reactants and less dactilitis, nail involvement, and anti-TNF-alpha usage.

Sarcoidosis presenting as penile mass.

Sarcoidosis is an inflammatory disease with unknown cause characterized by noncaseating granuloma formations. It may present with bilateral hilar lymphadenopathy, skin lesions, eye, and musculoskeletal system involvement. Rare involvement of the genital organs (prostate, testis, epididymis) has also been reported. However, penile involvement is observed quite rare. In this paper, we report a patient with penile mass who was diagnosed with sarcoidosis on the basis of the laboratory, radiological, and pathological investigations.
