Invasive Lymphangioma of the Lung Manifesting as a Large Pulmonary Mass with Hemoptysis: Report of a Case

Rare Diagnosis of a Multilobular Pulmonary Mass

CASE PRESENTATION

A 57-year-old woman was admitted to our hospital for an abnormal chest shadow found during routine chest radiography. She had no respiratory symptoms. Her medical history included dyslipidemia, and her surgical history included conization for cervical cancer at age 38 years. She was a social drinker and ex-smoker of approximately 10 cigarettes per day (from ages 20 to 30 years); she denied recreational drug use.

A case of intrapulmonary lymphangioma surrounded by pulmonary hilar structures

A 53-year-old man was referred to our hospital for examination of a nodule in the right hilar region observed on a chest roentgenogram. Computed tomography and magnetic resonance imaging revealed a 34 × 32-mm multilocular cystic mass with partial calcification adjacent to the hilar structures in the right upper lung lobe. The mass was resected using video-assisted thoracoscopic surgery and identified as pulmonary cystic lymphangioma through postoperative histopathological analysis. Intrapulmonary lymphangioma is an uncommon benign tumor, with only few reports of surgically resected cases. We describe our surgical findings and recommend surgical resection where possible for suspected intrapulmonary lymphangioma.

Rapid growing pulmonary cavernous lymphangioma after chronic process for ten years

•

Pulmonary cavernous lymphangioma very rarely appears as a solid tumour.

•

We encountered a case of pulmonary lymphangioma mimicking a malignant disease.

•

Surgical resection of lymphangiomas is recommended for both diagnosis and treatment.

Introduction

Solitary cavernous lymphangioma is very rare disease characterized by abnormally proliferating lymphatic vessels. We report a 49-year-old woman with a cavernous pulmonary lymphangioma showing rapid growth after remaining indolent for 10 years.

Presentation of case

Chest computed tomography revealed a solitary, poorly demarcated mass in the left lower lobe; however, the tumour grew in size over the next 6 months. A left lower lobectomy was performed following suspected lung cancer. Histopathological and immunohistochemical analysis of the resected specimens revealed a pulmonary cavernous lymphangioma.

Discussion

It is difficult to make an accurate diagnosis of solitary cavernous lymphangioma by imaging findings, therefore a surgical resection is recommended as the diagnostic and therapeutic modality.

Conclusion

A pulmonary lymphangioma should be included in the differential diagnosis of a rapidly growing tumour.
