Distant metastases favor the lung, liver, lymph nodes and skin. Metastatic pulmonary angiosarcoma commonly takes the form of a nodule but can sometimes appear as a thin-walled cyst. We report a case of 65 years-old male with a spontaneous pneumothorax, who underwent excision and radiotherapy for an angiosarcoma of the scalp 2 years ago. A chest CT scan revealed multiple cysts in the lung. The video-assisted thoracoscopic lung biopsy demonstrated subpleural cysts without tumor cells. A skin biopsy of the scalp showed an angiosarcoma. This case was diagnosed as a recurrence of an angiosarcoma with a supposed lung metastasis. This case suggests that a spontaneous pneumothorax in elderly people may be secondary to a pulmonary metastasis from an angiosarcoma of the scalp.

CJ Lee et al: Cystic lung metastasis of angiosarcoma Figure 3. On admission, Chest X-ray showed left pneumothorax. Figure 4. Subpleural cyst formation was seen in viedoassited thoracoscopic lung biopsy, but tumor cells were not seen (H&E stain, 10). Figure 5. Skin biopsy showed that cysts and intracytoplasmic spaces were formed by tumor cells (A, H&E stain, 200), which were positive for CD 31, marker of endothelial cells, on the immunohistochemical stain (B, 400). 았으며, 임상적으로폐로의낭성전이로판단하고 paclitaxel (70 mg/m 2 ) 로항암치료시작하였으나, 암전이가진행하여객혈및기흉지속되어사망하였다 (Figure 6). 고찰혈관육종은매우드문악성종양으로혈관의내피세포에서기원한다 1. 전체악성종양의 1% 이하를차지하며, 모든연조직육종의 2% 정도를이루는것으로알려져있다 2. 주로피부와표면의연조직에서발생하여, 노년의남성의얼굴, 두피, 목부위에서호발한다 2,3. 혈관육종의진 단시에이미전이가되어있는경우가많아서예후가불량하며, 주된전이부위는폐, 간, 림프절, 피부이다 4. 혈관육종이폐로전이되는경우객혈, 기흉, 혈흉등의호흡기증상을일으킬수도있다 5. Ukihide 등 6 의혈관육종의폐전이에대한흉부전산화단층촬영결과에대한연구에따르면폐전이가결절성병변을이루는경우가 63% 이고, 얇은벽의낭종을보이는경우가 21% 이었다. 병이진행하면서낭종의크기는커지며흉막하에위치하는경우에는기흉이나혈흉을일으키게된다. 낭종안에공기-액체층이 13% 에서관찰되었으며이는전이성병변의취약성으로인한출혈로생각된다. 376
Tuberculosis and Respiratory Diseases Vol. 64. No. 5, May. 2008 Figure 6. Chest CT scans revealed that multiple cysts have increased in size and number. During disease progression, increased ground glass opacity was observed and pneumothorax was recurred. 낭성변화를일으키는기전에대해서는여러가지가설이제시되고있다. 첫째, 결절성종양형성후에혈류장애로인해괴사되고괴사조직은빠져나가낭종이형성된다는것과, 둘째로종양색전에의해원위부폐실질이괴사되어낭종이형성된다는주장이있다. 셋째로는, 원래존재하던폐낭포주변으로종양세포가침윤한다는이론이있고, 넷째로종양이작은기관지를눌러서체크밸브역활을하여폐포를과다팽창시켜폐실질의낭성변화를일으킨다는것이다 7. 본증례의경우는폐의조직생검에서낭종의벽을이루는종양세포가관찰되지않아네번째이론에의한낭성변화로생각되며, 이로인해이차성기흉이발생한것으로여겨지나, 이런변화에대한연구는아직도진행중이다. Kitagawa 등 5 은 95예의부검을통해두피에서기원한혈관육종이다른부위에서기원한경우보다폐전이가더잘되어호흡기계합병증을더잘일으키는것으로보고하였으며, 특히기흉은두피기원의혈관육종환자에서만발견되었고매우불량한예후를나타낸다고하였다. 본 증례는 2년전두피의혈관육종을진단받고광범위절제술및수술후방사선치료를받은병력이있었으며당시시행하였던흉부전산화단층촬영상에서폐전이를시사하는소견은없었다. 2년후호흡기계증상이계속되어외래내원시촬영하였던양전자단층촬영-전산화단층촬영상에서폐의낭종이형성되어있었고병이진행하면서낭종이터져기흉이발생하여응급실로내원한경우였다. 기흉이재발하여다시내원했을때시행한신체검진에서두피의병변이새로이발견되어폐의쐐기절제술및두피조직검사를함께시행하여두피에서혈관육종의재발을확인하였으나폐조직검사에서는종양세포를관찰할수없었다. 혈관육종의폐전이를조직검사상에서확진할수없었으나병의진행경과를보고임상적으로폐전이를진단하였다. 두피의혈관육종을처음진단받았을당시의흉부전산화단층촬영상에서폐에서낭종이관찰되지않았으나호흡기증상과함께낭종이발견되기시작하였으며, 추적검사상에서폐의낭종이커지고출혈과기흉이반복되며진행하였기때문이다. 377
CJ Lee et al: Cystic lung metastasis of angiosarcoma 혈관육종의치료로는광범위절제술및수술후방사선요법이지만, 종양의범위를결정하기어렵고제거하기힘든위치에발생하는경우때문에완전히절제하기가어렵다. Pawlik 등 8 에따르면두피의혈관육종으로광범위절제술을받은 28명의환자중에서 6명 (21%) 만이절제후가장자리에서종양세포가발견되지않았다. 이연구에서 28명중 23명이방사선요법을받았으며, 방사선요법이국소부위의치료에도움이된다고주장하였다. 전신항암약물요법이혈관육종에효과가있다는것은입증되지않았으나, paclitaxel 이피부병변및폐전이에효과가있다는최근의연구보고들이있다 9,10. 본증례에서도 paclitaxel 로전신항암약물요법을 12회투여하였으나, 암전이가진행하여사망하였다. 본증례는혈관육종을진단받고치료받아관해를이룬상태에서객혈등의호흡기계증상을보여시행한영상학적검사상폐의낭종을진단받고이후낭종이터져기흉이발생되었던경우였다. 노년층에서기흉발생시에종양에의한이차성기흉을꼭감별하여야하며, 폐조직검사상종양세포가발견되지않더라도혈관육종의경우는폐전이소견이낭성변화일수있으므로이에대한확인이필요하다고판단되며문헌고찰과함께보고하는바이다. 요약혈관육종은매우드문악성종양으로고령남자의두피나얼굴에주로발생하며, 폐로전이되는경우가있다. 폐전이의경우객혈, 기흉등의호흡기계증상을일으킬수있다. 저자들은혈관육종의폐전이가낭성변화를일으켜기흉및혈흉을초래한 1예를경험하였기에문헌고찰과함께보고하는바이다. 1.
