Surgery treatment for pulmonary sclerosing hemangioma / 中华外科杂志

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the clinicopathological features and surgical treatment of pulmonary sclerosing hemangioma (PSH).</p><p><b>METHODS</b>Clinic data of PSH patients admitted by surgical resection from January 1985 to December 2010 was analyzed retrospectively. One hundred and sixty-five patients were enrolled in the study. There were 27 male and 138 female patients with a mean age of (48 ± 13) years. Seventy-nine patients were asymptomatic at the time of diagnosis. Eighty-nine tumors arose in the right lung (27 in right upper lobe, 24 in right middle lobe, 34 in right lower lobe, 2 in right upper lobe with invasion of right middle lobe, 1 in right middle lobe with invasion of right lower lobe, and 1 case with multiple lobe lesions), 75 in the left (33 in left upper lobe, 42 in left lower lobe), and 1 in the bilateral. There were huge mass lesions in 2 cases, endobronchial lesions in 2 cases, and multiple lesions in 6 cases. The mean size of the lesion was (2.6 ± 0.9) cm (ranging from 0.9 to 10.0 cm). Forty-eight cases (29.1%) were misdiagnosed as malignancies preoperatively, and 41 cases (24.8%) were misdiagnosed intraoperatively.</p><p><b>RESULTS</b>Resections were performed by means of video-assisted thoracoscopy (n = 53) and thoracotomy (n = 112). Surgical resection included pulmonary wedge excision in 61 patients, lobectomy in 89 patients, right bilobectomy in 5 patients, anatomic segmentectomy in 2 patient, enucleation in 6 patients, and synchronous bilateral pulmonary wedge resection in 1 patient. Operative mortality and morbidity occurred in 0 and 2 (4.3%) patients, respectively. Mean follow-up was 34.7 months (ranging from 6 to 62 months). There was no local recurrence or death from PSH.</p><p><b>CONCLUSIONS</b>PSH is a rare benign lung tumor. It is difficult to make accurate diagnosis preoperatively, and sometimes even intraoperative frozen sections can't differentiate it from malignant tumors. Surgical resection is usually indicated for definite diagnosis and treatment. Partial resection is a sufficient treatment in view of uncommon tumor recurrence. Thoracoscopic surgery is recommended for PSH.</p>
