Digital ischemia associated with lung cancer: a case report.
Digital ischemia or necrosis has unusually been associated with neoplasm. The occurrence of cryoglobulinemia and lung cancer with digital ischemia has been extremely rare in the past. This report concerns a case with adenocarcinoma of the lung associated with cryoglobulinemia, with rapidly developing digital ischemia of the tips of fingers and toes. Following concurrent chemoradiotherapy, there was improvement in digital ischemia and disappearance of serum cryoglobulin. The mechanisms of neoplasm-associated digital ischemia are complex; however, the cryoglobulinemia and probable arteritis may have played important roles in producing the ischemic symptoms in this case.
