33 Nonadenomatous dysplasia (small cell pattern). These cases show numerous, tiny glands that appear bland (but hyperchromatic) at low magnification, but that display nuclear alterations when examined at high power. Loss of nuclear polarity is evident here. patients are best served with close follow-up. We have seen a rare case of high-grade dysplasia in a patient taking colchicine for the treatment of gout. 154). 34 Lateral surface extension of dysplasia. Occasionally, dysplasia extends laterally on the surface of nonneoplastic cardiac or cadiac–oxyntic glands, as in this case.
51 Squamous cell carcinoma. This example of invasive squamous cell carcinoma is unassociated with overlying dysplasia. Instead the neoplastic cells appear to be “dipping down” from an abnormal basal layer. (tracheobronchial tree, aorta, and lung), and mediastinal lymph node metastases are more frequent clinical problems than distant metastases. Radiotherapy or chemotherapy is the usual treatment, sometimes with esophagectomy. However, this treatment is usually palliative, rather than curative. Esophageal squamous carcinoma has a dismal prognosis— the 5-year survival rate is 5% to 10%.
32 Basal crypt dysplasia. 31 better demonstrating enlarged, irregular, smudged nuclei with loss of nuclear polarity within the deep crypts. characterize BCD, we report this finding either in a descriptive diagnosis or as part of a comment if “indefinite for dysplasia” is offered as a diagnosis. Some examples of BCD show cytologic features identical to those of high-grade dysplasia. No clear guidelines exist regarding patient follow-up in this setting but most patients are probably best served if followed per LGD guidelines.
