Small-cell lung carcinoma produces salivary-type amylase: a case report with review.
A 53-year-old woman diagnosed with small-cell lung carcinoma (SCLC) was referred to our hospital because of general malaise and inappetence. Serum amylase levels were drastically elevated at 13,920 IU/l, with the salivary type dominating. She suffered multiple liver metastases and presented with disseminated intravascular coagulation (DIC). She succumbed to progressive malaise one month after admission. The amylase level was increased to 18,630 IU/l just before her death. Necropsy of the right supraclavicular lymph node confirmed SCLC with partial necrosis. Immunohistological analysis revealed that the SCLC produced salivary-type amylase. A rare case of salivary-type amylase-producing SCLC with a futile outcome was reported with review of the previous literature.
