Histopathological diagnosis of biopsy samples from early esophageal carcinoma.
Carcinoma of the esophagus is frequently diagnosed in advanced clinical stages. When an esophagic carcinoma has infiltrated the submucosa or the muscular or serosa, metastases are a common finding. Thus, early diagnosis and opportune treatment are vital for patients with this type of neoplasm. Timely diagnosis can be done through endoscopic or X-ray studies and confirmed through a histopathological study by directed biopsy. We presently report the case of a 65 year old man with precedents of achalasia who underwent an endoscopic study using the Lugol staining technique for suspected malignant lesion classified as 0-IIc. After two biopsies it was diagnosed as early carcinoma of the esophagus and was subjected to mucosectomy. Histopathological findings are reviewed at architectural and cellular level and are essential to establish the diagnosis of early neoplastic lesions of the esophagus epithelium. These cellular changes are corroborated by immunohistochemical studies with nuclear expression of p53. The relevant literature was reviewed and experiences by Japanese and North American pathologists compared with emphasis on the need for multidisciplinary management to make an early diagnosis by endoscopic studies, Lugol staining, X-rays, biopsy and conservative treatment based on mucosectomy.
