Sclerosing hemangioma of the lung: An analysis of 8 cases

Background: Sclerosing hemangioma (SH) of the lung is a rare benign tumor. Few studies have evaluated the clinicopathological features and the surgical outcomes of this tumor. Aim: We aimed to evaluate clinical manifestations, radiological findings, and treatment outcomes of this tumor. Methods: We retrospectively reviewed eight cases of pulmonary sclerosing hemangioma diagnosed at our institution from January 2006 to April 2014. Results: There were four female and four male patients. The age at the time of diagnosis ranged from 23 to 79 years, with a mean age of 56.1 years. Two patients were asymptomatic. Among six symptomatic patients, hemoptysis is the most frequent symptom. The radiological appearance was a solitary nodule or mass in seven cases. In remaining case, there were multiple distinct masses and nodules in bilateral lung fields. The tumor involved lung parenchyma in seven cases and endobronchially located in remaining patient. Seven patients underwent surgery. Surgical procedure was wedge resection in four patients, lobectomy in two patients, and tumor enucleation in one patient. Diagnosis of SH was established by surgical biopsy in seven cases and by bronchoscopic biopsy in one case. The most common histological pattern was solid pattern. During the follow-up ranging from 2 months to 76 months, seven cases who underwent surgery had an excellent prognosis with no evidence of recurrence following surgery. The patient with multiple lesions died 1 month after diagnosis. Conclusions: Sclerosing hemangioma of the lung is a rare tumor. Surgical resection usually requires for both diagnosis and treatment of this tumor. The patients had excellent prognosis with no evidence of recurrence following surgery.
