&NA;Primary linitis plastica of the colon is an uncommon tumor, with only 22 cases having been previously reported. Experience with two men and one woman between 17 and 55 years of age, portraying a spectrum of clinical presentations ranging from rectal bleeding to large‐bowel obstruction, is reviewed. Clinical and radiologic characteristics and histologic features helpful in making the diagnosis are detailed. Though the prognosis is grim, resective surgery, including oophorectomy in women, should be undertaken. Adjuvant therapy has been disappointing.
