Clinicopathologic Features of Gastric and Gastrooesophageal Junction Adenocarcinoma.

Gastric cancer (GC) is one of the most common tumors and remains the second leading cause of cancer mortality in the world. The incidence of gastric carcinoma is declining in the last few years in some areas like USA, UK, Canada etc, because of reduction in chronic H. pylori infection, smoking, decrease use of smoked and salted food. The gastric carcinoma still remains a burden for Bangladesh as the prevalence of H. Pylori has not substantially decreases. Among the gastric carcinomas, adenocarcinomas are the most common type. So the study was performed to observe the location and histomorphologic pattern of Gastric and gastrooesophageal junction (GEJ) adenocarcinoma. This descriptive cross sectional study was carried out at the Department of Pathology, Dhaka Medical College, Dhaka, Bangladesh from January 2013 to December 2014. A total of 130 patients with primary gastric and GEJ adenocarcinomas were included in this study. All the cases were evaluated for routine histological examination. The age range of the patients was 17 to 80 years and male to female ratio was 2.25:1. Antrum is the most common (66.9%) site being affected, followed by GEJ (19.2%), body (13%) and fundus (0.76%). Tumors of the antrum and GEJ were found mostly in the late age. On macroscopic examination, the ulcerated tumor mass (69.2%) was most frequent then the others. Regarding histological examination, 84(64.6%) cases were intestinal type, 32(24.6%) diffuse and 14(10.8%) mixed type by Laurens classification. According to WHO classification, about half of the cases (49.2%) were tubular carcinoma and rest were others. Most of the intestinal type carcinoma (71.4%) was presented with moderately differentiated and 25.0% with well differentiated. Where as the diffuse type presented with poorly differentiated in 96.9% cases.

Steatocystoma Simplex on the Scalp: A Case Report.

Steatocystoma is a benign adnexal tumor arising from the pilosebaceous duct junction. It can be classified into two groups (steatocystoma simplex and steatocystoma multiplex). Steatocystoma simplex, which presents as a solitary, non-herited very rare lesion in adult. It occurs most commonly in the axillae, in the sternal region and on the arms. Scalp is an extremely rare location. We report a case of 49-years-old male admitted in Department of Surgery, Dhaka Medical College & Hospital, Dhaka, Bangladesh on February 2017 presented with slowly progressing painless, soft, yellowish, single smooth surface mass on the left parietal scalp which had persisted for a period of 8 years. The histopathologic examination revealed a thin-walled cyst consisting of stratified squamous epithelium with lack of granular layer and containing sebaceous gland close to the wall. These findings were consistent with steatocystoma. At the 4-month follow-up, there was no sign of recurrence or development of the steatocystoma or any other masses.
