skip lesion

Any lesion in which normal tissue is interspersed with tissue affected by a pathologic condition. Skip lesions occur in metastatic carcinoma, polyarteritis nodosa (interspersed “skipping” or sparing of vessels), Crohn’s disease (interspersing of involved and relatively normal intestine), radiologically and on gross examination; it is regarded as a “classic” feature, but only occurs in 20–25% of cases.
