Acquired ichthyosis was recognized in four patients, in whom the associated malignant disorders were carcinoma of the lung, breast, and cervix. This skin lesion may be a valuable clinical sign in recognizing the existence of a malignant condition. Although the emergence of an ichthyosiform dermatosis may have serious prognostic implications, it may also be useful in monitoring the course of the malignant disorder and the patient's response to therapy. The relationship to nonlymphoproliferative malignant neoplasms may be more common than has been previously recognized

The influence of EACA on C1 in whole human serum and on C1 and C (see article) as isolated molecules was assessed hemolytically. There was selective inhibition of C1 without effect on the levels of C4, C2, C3, and C9 in whole human serum that was reversed by dialysis. EACA was found to inhibit the intrinsic activation of C1 without inhibiting the already active molecule. This was confirmed by the capacity of trypsin to uncover C1 activity in cellular intermediates formed by C1 treated with EACA that did not evolve in the absence of this extrinsic activating mechanism. Inasmuch as the trypsin-dependent recovery of C1 was incomplete, an effect on binding cannot be excluded
