RESUMO
Background: Sarcoidosis is a noncaseating granulomatous disease that predominately occurs in the lungs. Vitiligo is the most common depigmentation disorder worldwide. Both diseases are autoimmune-mediated, suggesting that one could have implications for the other. However, relatively few reports have been published about patients presenting with coinciding symptoms of the 2 diseases. We report the case of a patient who presented with focal repigmentation of vitiligo with suspected pulmonary sarcoidosis. Case Report: A 63-year-old female with a medical history of diffuse vitiligo reported to the emergency department with the chief complaint of right lower extremity weakness and numbness for 1 week. She reported that she had had a chronic productive cough for the prior 4 to 6 months and had unintentionally lost 50 to 60 pounds in the prior 3 months. At that time, she began to notice numerous hyperpigmented macules and patches on both forearms and her face. Chest x-ray and chest computed tomography demonstrated bilateral hilar and mediastinal lymph node enlargement with multiple bilateral pulmonary nodules. Cytology and flow cytometry were negative for evidence of B- or T-cell lymphoproliferative disorder with evidence of granulomatous inflammation. Conclusion: This clinical presentation suggests a potential interplay between 2 unique disease processes. While both vitiligo and sarcoidosis share common autoimmune etiologies, little data are available about management when they coincide. This case highlights a patient with 2 seemingly distinct clinical manifestations that could yield further clinical information in the management of both diseases separately and together.
RESUMO
BACKGROUND: New onset or acute worsening of bilateral lower extremity swelling is commonly caused by venous congestion from decompensated heart failure, pulmonary disease, liver dysfunction, or kidney insufficiency. A thromboembolic event, lymphatic obstruction, or even external compression of venous flow can also be the culprit. CASE REPORT: We report the case of an 83-year-old male with a history of myelodysplastic syndrome that progressed to acute myeloid leukemia, bipolar disorder, and benign prostatic hypertrophy. He presented with altered mental status and new onset lower extremity edema caused by acute bladder outflow obstruction. Computed tomography of the abdomen and pelvis showed the patient's distended bladder compressing bilateral external iliac veins. CONCLUSION: Insertion of a Foley catheter resulted in several liters of urine output and marked improvement in his lower extremity edema and mental status a few hours later. Our extensive workup failed to reveal a cause of the patient's acute change in mental status, and we attributed it to a concept known as cystocerebral syndrome.
RESUMO
A 63-year-old woman with a history of infiltrating ductal breast cancer, status post-mastectomy and chemotherapy, was in remission for 18 months prior to being admitted to the hospital with complaints of a pruritic erythematous macular rash involving her head, chest, and bilateral upper and lower extremities. Along with the dermatologic manifestations, physical exam revealed proximal symmetrical muscle weakness and bilateral axillary lymphadenopathy. Initial workup for muscle weakness revealed a creatine kinase of 2,200 IU/L (normal 20-180 IU/L). After administration of intravenous fluids for renal protection, serum sodium dropped to 121 mEQ/L (normal 135-145 mEQ/L). Computed tomography of the chest showed axillary and supraclavicular lymphadenopathy. Biopsy of a supraclavicular node revealed infiltrating ductal cancer with histologic and morphologic characteristics similar to her previous breast cancer. Following an extensive laboratory workup, we concluded that our patient's myositis and hyponatremia were paraneoplastic syndromes secondary to her recurrent breast cancer.
