Histopathological types of malignant lesions of esophagus and stomach.
Upper part of gastrointestinal tract is common site of malignancy. Histological types of malignancy of esophagus and stomach may vary in different countries and also in different regions in the same countries. To find out the frequencies of different histological malignancies in Mymensingh region of Bangladesh, we analyzed the histopathological reports of 259 biopsy specimens examined in one pathology laboratory in Mymensingh town during the period from 6th January 2002 to 29th April 2004. Endoscopic biopsies were 234 (90.35%) and surgical biopsy specimens were 25 (9.35%). Male patients were 193 (72.52%) and female patients were 66 (25.48%). Specimens of esophagus were 73 (28.19%) and of stomach were 186 (71.81%). Out of 69 (94.53%) adequate samples of esophagus 46 (74.19%) were squamous cell carcinoma and 16 (25.81%) were adenocarcinoma. Adequate samples of stomach were 177 (95.16%) in which malignancies were found in 119 (67.23%). All the malignant tumor of stomach were in adenocarcinoma of which 82 (68.91%) were intestinal type, 17 (14.29%) were diffuse type and 20 (16.81%) mixed type. Intestinal type of gastric adenocarcinoma was found to be significantly associated with male patients (p < 0.005). From the present study it is suggested that in the Mymensingh region the common form of malignant lesion of esophagus may be squamous cell carcinoma followed by adenocarcinoma. Adenocarcinoma is the most common type of gastric malignancy of which intestinal type is more common
