Scalp angiosarcoma presents with spontaneous pneumothorax secondary to expanding cystic pulmonary metastasis.
Case Report (n=1)
Highlights the aggressive nature of angiosarcoma and the potential for pulmonary metastasis presenting as thin-walled cavitary lesions and spontaneous pneumothorax.
Spontaneous pneumothorax may signal cystic pulmonary metastases in angiosarcoma; single case leaves open need for prospective evaluation.
Angiosarcoma (AS) is a rare malignant tumor that originates from endothelial cells, and has an extremely poor prognosis. AS is frequently accompanied by pulmonary metastasis with a presentation of thin-walled cavitary lesions. We report a patient with AS manifesting as spontaneous pneumothorax secondary to pulmonary metastasis, which increased in size over the clinical course of several months. This case illustrates the need for awareness of the aggressive nature of this tumor and to suspect metastasis when pulmonary complications develop.

Kim et al. (2011) conducted a case report in Scalp Angiosarcoma with pulmonary metastasis (n=1). Scalp Angiosarcoma was evaluated on Clinical course of pulmonary metastasis. A patient with scalp angiosarcoma developed spontaneous pneumothorax secondary to cystic pulmonary metastasis, which increased in size over several months.
