Endobronchial Lipoma Accompanied with Primary Lung Cancer: Report of a Case

Abstract

A 72-year-old man was found to have an endobronchial lipoma accompanied with primary lung cancer. A left lower lobectomy with a mediastinal lymph node dissection and a sleeve resection of the lingual bronchus with telescoping bronchial anastomosis were done. The pathological staging was T1N2M0, stage IIIA. A histological examination showed well-differentiated squamous cell carcinoma in segment 10, in addition to the presence of mature adipose tissue which was diagnosed to be a benign endobronchial lipoma originating from the lingual bronchus. The postoperative course was uneventful and the patient was discharged 13 days after the operation. However, he had a recurrence in the subcarinal lymph node, and died 8 months after surgery.

Hemoptysis caused by an endobronchial lipoma

“…A new type of diaphragmatic hernia: Anterolateral hernia JØrôme Mouroux, MD, PhD, Daniel Pop, MD, Patrice Guiraudet, MD, Ricardo Giovanetti, MD, JØrôme Lauron, MD, and Nicolas Venissac, MD, Nice, France H eterogenous types of acquired hernias in the diaphragm have been described in the literature: the hiatal hernia through the esophageal foramen and the posterolateral hernia through the Henle costolumbar orifice or anterior foramen of Larrey-Morgagni hernia (retroxiphoid hernias). 1,2 To our knowledge, no anterolateral hernia has been reported. We describe the case of a hernia between the eighth and ninth anterior costochondral insertion of the muscular fibers of the diaphragm.…”

“…Almost two thirds of the tumors occur in the right side, and they are usually located in the main-stem or lobar bronchi. [1][2][3] Smoking and obesity are significant risk factors for EL development. 4 Cough, hemoptysis, and shortness of breath are common symptoms, 4,5 and patients are often misdiagnosed and treated for asthma for many years, as was our patient.…”

“…EL sometimes coexists with lung cancer, especially in patients who have smoked heavily. 1 Bronchoscopic resection should be considered the first choice of treatment for EL; Muraoka and associates 2 report that no patient presented with bronchial tumor recurrence after EL bronchoscopic resection. Tumor surgical resection is preferred in some cases: (1) extrabronchial growth or subpleural lipomatous disease; (2) expected technical difficulties during the bronchoscopic resection;…”

An unexpected encounter and outcome between endobronchial lipoma and carcinoma: a case report and literature review

“… 7 , 8 Endobronchial lipomas occur predominately in men aged 50–80 years old, but rarely in women. 1 – 5 , 7 – 10 Clinical symptoms in the vast majority of patients include cough, expectoration, hemoptysis, asthma, fever, and dyspnea, but there is no typical symptom. 1 , 9 , 10 It is well known that smoking and obesity are risk factors, but neither of these factors is found in our patient.…”

Lipoma endobrônquico

“…(8)(9) In some cases, there might be concomitant neoplastic disease, principally primary pulmonary tumor. (10) In a recent review of the Japanese literature, it was shown that 64 cases of endobronchial lipoma were reported between 1971 and 2001, accounting for 0.1% to 0.5% of all pulmonary tumors. (11) In the search for endobronchial lesions of adipose origin, chest X-rays are nonspecific.…”
