Abstract
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. Laboratory workup was significant for leukopenia (2900 K/UL), serum creatinine level of 2.7 mg/dL (baseline: 1.2-1.7), and raised angiotensin-converting enzyme level at 187 nmol/ml/min. Chest X-ray showed bilateral widespread fine reticulonodular opacities, chest CT showed extensive bilateral reticulonodular opacities throughout the lung parenchyma, and fine-needle aspiration cytology of the right lung showed noncaseating granulomas. No fungal or acid-fast organisms were identified, and no evidence of malignancy was seen. Special stains for fungal (Grocott's methenamine silver and periodic acid-Schiff) and acid-fast organisms (acid-fast bacilli (AFB) and fluorescent AFB) were negative. Esophagogastroduodenoscopy (EGD) with gastric biopsy showed acute and chronic inflammation and no intestinal metaplasia, dysplasia, or malignancy was identified. Bronchoalveolar lavage was done, which showed macrophages (74%), neutrophils (6%), eosinophils (3%), and lymphocytes (17%), and was negative for malignant cells. QuantiFERON and AFB sputum/Mycobacterium tuberculosis polymerase chain reaction were negative. The patient was initially started on intravenous fluids and calcitonin, which significantly improved renal function and the calcium status of the body. Then prednisone 40 mg daily was started, which improved swallowing and breathing. After a week, prednisone was changed to 20 mg daily and was continued at the time of discharge.
