Nic mucosa in this patient raise a second interesting consideration. In our previous description of the histopathologic features associated with colchicine in gastrointestinal tract biopsies, the finding of abundant metaphase mitoses, nuclear pseudostratification, and loss of polarity was present only in those patients with clinical colchicine toxicity. viagra without a doctor prescription india (3) biopsies from patients who were receiving colchicine but not at toxic levels did not show these distinctive morphologic features. (3) in the current case, these features were present only in the sigmoid polyp and were not manifest in the biopsy of endoscopically normal mucosa from the cecum. Additionally, careful review of this patient's medical history and laboratory values failed to reveal any evidence of colchicine toxicity. We hypothesize that colchicine effect in this case was manifest only in the region of increased proliferative activity, and that the normal mucosa was unaffected because the patient's colchicine level was not toxic. These findings would be expected, based on the results of our previous study (3) and other studies showing that colchicine preferentially affects tissues with the most proliferative activity. (2,10) in summary, recognition of the distinctive features of colchicine effect in this hyperplastic polyp avoided confusion with serrated adenoma; correspondingly, absence of these features in the nonpolypoid colonic mucosa supported the lack of clinical colchicine toxicity in this patient.
