Syncope as the initial presentation of pulmonary embolism in a young adult with testicular tumor: A case report and literature review.

RATIONALE

Venous thrombus embolism (VTE) includes deep-vein thrombosis (DVT) and pulmonary embolism (PE) which may be an initial symptom for patients with cancer. PE has diverse clinical manifestations and is a rare complication of testicular tumor (TT).

PATIENT CONCERNS

Here, we report a 21-year-old man admitted to our hospital due to syncope.

DIAGNOSES

Clinical examinations upon admission demonstrated PE resulting in syncope. Further, a malignant TT, liver metastasis, and inferior vena cava (IVC) thrombosis were diagnosed.

INTERVENTIONS

Low molecular heparin was administered immediately after PE was diagnosed.

OUTCOMES

The patient suffered from cardiac arrest on hospitalization.

LESSONS

Physicians should consider the possibility of TT when a young male patient presents with syncope and is diagnosed with PE that cannot be explained by a common cause. Treatment for TT and PE should be performed as early as possible to improve the prognosis of patients combine with TT and PE.
