Pulmonary pleomorphic liposarcoma

Abstract

Pulmonary liposarcoma is extremely rare with 6 cases previously reported in the English literature. The following is a report of a 36-year-old man with pulmonary liposarcoma. The patient had chest pain and a mass shadow in the right lower lung field was revealed on a chest X-ray film. A computed tomography and magnetic resonance imaging showed a heterogeneous tumor, compressing the right lower lobe of the lung. Because of the fatty tissue component in the tumor on the chest computed tomography, and the appearance as an extrapulmonary mass, preoperative diagnosis was posterior mediastinal liposarcoma. But thoracotomy revealed that the tumor originated from the lung. Right lower lobectomy and lymph node dissection was carried out with no additional therapy. The pathological diagnosis was pleomorphic liposarcoma originated from the lung. Two months after the operation, the patient died of respiratory failure due to local recurrence.

Primary dedifferentiated liposarcoma of the lung with rhabdomyoblastic and chrondroblastic differentiation

“…Previous reports of primary lung liposarcoma have described small numbers of myxoid, pleomorphic and unclassified subtypes, and only one dedifferentiated case. A lung liposarcoma arising in a hamartoma was of a well‐differentiated subtype .…”

“…Sir : Primary liposarcomas of the lung are rare, with fewer than a dozen having been reported in the literature . Among these, only one dedifferentiated liposarcoma has been described .…”

“…Sir: Primary liposarcomas of the lung are rare, with fewer than a dozen having been reported in the literature. [1][2][3][4][5][6][7][8] Among these, only one dedifferentiated liposarcoma has been described. 7 Here, we present a second case of primary dedifferentiated liposarcoma of the lung, in this instance showing rhabdomyoblastic and chondroblastic differentiation.…”

Primary intrathoracic liposarcoma: a clinicopathologic study and prognostic analysis of 23 cases

“…Radiotherapy had also been of some value as an adjuvant treatment for the myxoid type [11-13]. Since the limited data, we didn’t draw the conclusion.…”

Pleomorphic liposarcoma: A cytologic study of five cases

“…PLS is a rare variant of LS with a poor prognosis. These tumors are most commonly located in the upper or lower extremity but PLS has also been reported in a variety of other sites including: the orbit, retrotonsillar fossa,parotid as well as the mediastinum, pericardium, lung,breast,and bone, dura, and subcutaneous tissues . Location of a primary lesion in a nonextremity site appears to be associated with an even more aggressive course and worse outcome than with an extremity based tumor .…”
