Angiomyolipomas are benign, solitary, noninvasive mesenchymal tumors. They most often arise in the kidney. Extrarenal presentations of these tumors are in skin, orophaynx, abdominal wall, gastrointestinal tract, heart, lung, liver, uterus, penis, and spinal cord. Angiomyolipoma of the mediastinum is extremely rare and is composed of an admixture of fat, smooth muscle cells, and tortuous, thick-walled, small to medium sized blood vessels. We present a surgically confirmed case of anterior mediastinal angiomyolipoma incidentally diagnosed in an asymptomatic patient.

CASE REPORT A 32-year-old Japanese man with a 1-month history of headache and 2-week history of facial swelling underwent chest computed tomography (CT); a diffuse mass-like lesion was revealed in the anterior mediastinum with severe stenosis of vital mediastinal organs.

Aim: This study had two aims: to analyze surgical patients with mediastinal cysts and masses according to clinical, histopathological, and surgical types; and compare the impact of the coronavirus disease 2019 (COVID-19) pandemic on these cases.
Methods: A retrospective analysis was conducted on 132 patients who had undergone surgical intervention for mediastinal cysts and masses. Demographic, clinical, and histopathologic data were recorded.

Hodgkin's lymphoma (HL) is a malignancy of the lymphocytes in the lymph nodes and presents with non-specific systemic symptoms like fever, night sweats, and weight loss. While HL often involves the mediastinum, it rarely causes superior vena cava (SVC) syndrome, and eosinophilia is noted in approximately 15% of cases. Here, we report a unique presentation of HL in a 52-year-old male with a history of chronic pruritus, chronic kidney disease, and inactive hepatitis B.

This study retrospectively evaluated the computed tomography (CT) findings of idiopathic multicentric Castleman disease (iMCD) at a single center and compared the CT findings of iMCD-TAFRO with those of iMCD-non-TAFRO. CT images obtained within 30 days before diagnostic confirmation were reviewed for 20 patients with iMCD (8 men and 12 women, mean age 52.8 ± 12.

A 59-year-old woman presented with multiple mediastinal masses 6 months after post-thymectomy for type B2 thymoma. A diagnosis of small-cell carcinoma (SmCC) via a computed tomography-guided biopsy and fluorine-18-fluorodeoxyglucose positron emission tomography/computed tomography revealed no primary lesions outside the anterior mediastinum. The pathologically reevaluated post-thymectomy specimen showed no neuroendocrine differentiation.
