Alveolar soft-part sarcoma is a slow-growing but nevertheless malignant soft tissue tumour arising in muscle. It occurs most frequently in young women and often presents as a painless swelling in an upper or lower limb. The swelling, which may have been present for a considerable time, is firm and appears to be well circumscribed but it may recur locally after excision. Blood-borne metastases to the lung are common and this is frequently the mode of presentation. Lymphatic metastases are unusual. The tumour is composed of nests of large cells and the histological appearances may resemble those of a renal adenocarcinoma (hypernephroma). Six new cases of this very rare tumour are presented and the published reports are reviewed.
肺泡软组织肉瘤是一种生长缓慢但却是恶性的起源于肌肉的软组织肿瘤。它最常见于年轻女性，常表现为上肢或下肢的无痛性肿块。该肿块可能已存在相当长一段时间，质地坚硬，边界似乎清晰，但切除后可能会局部复发。血行转移至肺部很常见，这也是其常见的表现形式。淋巴转移不常见。肿瘤由大细胞巢组成，组织学表现可能类似于肾腺癌（肾上腺样瘤）。本文报告了6例这种非常罕见的肿瘤新病例，并对已发表的报告进行了综述。
