Pulmonary epithelioid hemangioendothelioma (P-EHE) is a rare disease. Thus far, consensus on a standard treatment for P-EHE has not been established given its low incidence worldwide. Apatinib combined with chemotherapy with doxorubicin/cyclophosphamide has been used as an effective combination treatment for human malignancies. However, the efficacy of this combination has not been reported in P-EHE cases.
We present the case of a 64-year-old woman with chest tightness, cough, and chest pain. Computed tomography showed multiple unresectable pulmonary nodules. She had been misdiagnosed with lung carcinoma and underwent gefitinib treatment at a hospital. Subsequently, the patient underwent a cardiothoracic surgery for further disease investigation. CD31, CD34, and Vimentin expression were detected in the resected nodule specimens by immunohistochemical analyses, and pathological analyses confirmed the diagnosis of P-EHE. Following this, four cycles of apatinib combined with chemotherapy with doxorubicin/cyclophosphamide were initiated. The patient demonstrated stabilization of multiple bilateral nodules and showed a dramatic improvement in the clinical presentation after combination treatment. The patient could not tolerate the side effects of chemotherapy. Therefore, she then continued apatinib monotherapy, which is ongoing to date. The patient was stable at the last follow-up after 24 mo.
Apatinib combined with chemotherapy with doxorubicin/cyclophosphamide may be an effective therapeutic option for P-EHE treatment.
Core tip: Pulmonary epithelioid hemangioendothelioma (P-EHE) is a rare disease. Patients with P-EHE demonstrate multiple unilateral or bilateral nodules that are often misdiagnosed as lung cancer or suspected to represent lung metastases. Meanwhile, currently, no standard treatment for this rare disease exists, and patients with P-EHE show a poor prognosis. Therefore, an effective therapeutic strategy for these patients is urgently required.
