[Hodgkin's disease with a giant thymic cyst]

Area of Science:

• Oncology
• Pathology

Background:

• Mediastinal masses can present diagnostic challenges.
• Anterior mediastinal masses require thorough investigation.

Observation:

• An asymptomatic 26-year-old male presented with an abnormal mediastinal shadow.
• Chest CT revealed a large anterior mediastinal mass with para-aortic lymphadenopathy.
• The mass exhibited multiloculated low-density areas with enhancing parenchymal rims.

Findings:

• Surgical resection of the cystic tumor and lymph nodes was performed.
• Pathological examination confirmed a thymic cyst.
• The cyst wall contained Hodgkin's lymphoma, including lacunar and Reed-Sternberg cells.

Implications:

• This case highlights a rare presentation of Hodgkin's lymphoma within a thymic cyst.
• Accurate pathological diagnosis is crucial for effective treatment planning.
• Further research into rare mediastinal malignancies is warranted.
