Signet ring cell carcinoma is a unique mucin secreting adenocarcinoma. It generally arises from stomach, colon, rectum or breast and rarely from lung. Pleural membrane involvement is common in lung cancer manifesting as pleural effusion. Rarely, it may encase the whole lung without effusion mimicking mesothelioma and is termed as "pseudomesothelioma". A 35-year-old male presented with a pleural mass encasing the whole of the right lung without any pleural effusion and investigations revealed it to be primary signet ring cell adenocarcinoma of the lung.
印戒细胞癌是一种独特的分泌黏液的腺癌。它通常起源于胃、结肠、直肠或乳腺，很少起源于肺。肺癌中胸膜受累常见，表现为胸腔积液。罕见的情况下，它可能在无积液的情况下包裹整个肺，类似间皮瘤，被称为“假间皮瘤”。一名35岁男性因一个包裹整个右肺的胸膜肿块就诊，无任何胸腔积液，检查显示为原发性肺印戒细胞腺癌。
