Patient with positional wheezing due to endobronchial lipomatous hamartoma.

Endobronchial hamartoma is a rare form of pulmonary hamartoma, and endobronchial lipomatous hamartomas are even rarer. We describe the case of a 39-year-old man who presented with a two-year history of dyspnea on exertion and wheezing over the left chest only while lying on his left side. The patient was diagnosed with endobronchial lipomatous hamartoma occluding the left main bronchus. He underwent a superior segmentectomy of the left lower lobe, which promptly relieved the dyspnea and positional wheezing. To our knowledge, fewer than 10 such cases are cited in the English literature, none of which presented with positional wheezing. This patient represents the first case of focal and positional wheezing resulting from endobronchial lipomatous hamartoma. © Georg Thieme Verlag KG Stuttgart · New York.
