- Adenoacanthoma of the stomach is a rare lesion of obscure origin. Approximately 43 anthenticated cases of primary adenoacanthoma of the stomach have been compiled since the first description made by Rolleston and Trevor in 1905. No special clinical features could be found which help to separate this unusual cell type from the usual adenocarcinoma.
Three theories concerning the origin of these unusual tumors are 1) squamous cell metaplasia. 2)heterotopic islands of squamous cells, and 3) tumor cells arising from the direct stimulation of undifferentiated multipotential cells in gastric mucosa.
A 37-year-old Korean male was admitted to Seoul National university Hospital because of rapid weight loss, vomiting and epigastric fullness of 3 months duration. Physical examination revealed a 47kg. weighing male, but showing essentially negative in that no abdominal masses were palpable, no lymphadenopathy was noted, and rectal examination was normal. The significant laboratory data included an upper gastrointestinal series which demonstrated an large filling defect in pyloric antrum along the greater curvature, and findings of pyloric stenosis.
The resected stomach contained a polypoid, focally ulcerating neoplastic mass measuring 4 cm. in maximum cross, which is infiltrating deep into muscularis. Serosa is partly involved grossly by neoplastic tissue, and several swollen lymph nudes were encountered along the greater curvature. Microscopic examination revealed infiltrating tumor masses that are comprised partly by differentiated, focally pearl forming squamous cell nests invading into external muscularis. In areas there are atypical glandular component, with evidence of mucin production.

Abstract
PDF
- An autopsy case of a congenital sacrococcygeal teratoma in a dead born fetus of eight months gestation is reported. The fetus weighs 1.3 kg. and reveals a large protruding tumor mass in sacral region, measuring 14×10×10 cm. and weighing 400 gm. The tumor is completely covered with skin. The tumor masses are partly cystic and partly solid with variegated appearance on cut sections. Anteriorly the tumor is partly extending into spinal canal.
Microscopically the tumor is composed of various elements derived from trigerm layers. Most prominent elements are central nervous tissue with considerable amount of choroidal plexus. No evidence of malignancy is noted.
There are found no congenital anomalies except for the teratoma.
Brief review of literature is made.

Abstract

- A Pathologic study is made on 44 cases of retroperitoneal tumors of koreans, obtained during a period of 12 yearn, 1956-1967, at the Department of Pathology, College of Medicine, Seoul National University, and following are the results. 1. Poorly four retroperitoneal tumors examined consist of 7 (15.9%) benign and 37 (84.1%) cases of malignant tumors.
2. Thirty seven malignant and seven benign retroperitonea] tumors are histologically classified and tabulated. Among malignant tumors, Liposarcoma 9(20.4%), malignant Lymphoma (13.6%), metastatic Tumors (9.1%), and malignant teratoma (6.81%), especially prevalent, and among benign tumors, benign teratoma 3(6.8%) is more commonly encountered,.
3. Overall age distribution shows highest peaks of benign tumors in age range 31∼40 and of malignant in 51∼60. Average ages of malignant and benign retroperitoneal tumors are 40 and 28 years respectively.
4. Male is slightly preponderant than female
