RESUMO
BACKGROUND: Mucoepidermoid carcinoma of the lung is a rare malignant tumor, accounting for 0.1%-0.2% of all lung malignancies. It is a primary salivary gland tumor of the lung. Surgical resection is the primary treatment for pulmonary mucoepidermoid carcinoma, for which there has been no standardized treatment strategy. This article reports a case of a young woman with pulmonary mucoepidermoid carcinoma with hemoptysis as the first symptom. CASE SUMMARY: A 24-year-old female patient presented with "4 d of hemoptysis" as the chief complaint. She had no special history and denied any smoking or drinking history. Physical examination revealed that the vital signs were stable and scattered small wet rales were heard in the left lung. After admission, the lung tumor markers were checked, and no abnormalities were found. After completing the bronchoscopy, a spherical lesion was observed at the main bronchus 1.5 cm away from the protubercle, with obvious pulsation and little blood seepage on the surface, and histopathological biopsy results showed acute and chronic inflammation. She was transferred to the Department of Thoracic Surgery for surgical treatment on the 16th day after admission. After exclusion of surgical conjunctures, the patient underwent resection of the tumor in the left main bronchus with single-pore video-assisted thoracic surgery on the 19th day after admission. The postoperative histopathological biopsy results showed mucoepidermoid carcinoma of the lung. The patient and her family refused to complete genetic testing and she was discharged from the hospital on the 8th day after surgery. During the follow-up period, the patient experienced shortness of breath after feeling active and had no special discomfort. CONCLUSION: We have documented a case of moderately differentiated mucoepidermoid lung cancer with hemoptysis as the first symptom to improve clinicians' understanding of the disease and provide a new dimension of thinking for its future diagnosis and treatment.
RESUMO
BACKGROUND: Behcet's disease (BD) is a chronic disease characterized by oral and vulvar ulcers as well as eye and skin damage and involves multiple systems. It presents as an alternating process of repeated attacks and remissions. Esophageal venous rupture and bleeding caused by BD is rarely reported at home and abroad. This paper reports a case of bleeding from oesophageal varices caused by BD, aiming to provide an additional dimension for considering the cause of bleeding from esophageal varices in the future. CASE SUMMARY: A 38-year-old female patient was admitted due to a gradual increase in shortness of breath and chest tightness after the activity, and was admitted to our hospital for treatment. After admission, relevant examinations showed that the patient had multiple blood clots. Four days after admission, she suddenly experienced massive hematemesis. Emergency esophagogastroduodenoscopy revealed bleeding from esophageal and gastric varices. The patient had no history of viral hepatitis or drinking habits, and no history of special genetic diseases or congenital vascular diseases. There is no obvious abnormality in liver function. After reviewing the medical history, it was found that the patient had recurred oral ulcers since childhood, ulcers were visible in the perineum during menstruation, and there was an intermittent red nodular rash and uveitis. The current skin acupuncture reaction is positive, combined with the evaluation of the external hospital and our hospital, the main diagnosis is BD. She received methylprednisolone, cyclophosphamide, immunomodulation, acid suppression, gastric protection, and anticoagulation and anti-infection treatments, and was discharged from the hospital. During the 1-year follow-up period, the patient did not vomit blood again. CONCLUSION: This case highlights bleeding from esophageal varices caused by BD, aiming to provide an additional dimension concerning the cause of bleeding from esophageal varices in the future.
