The first edition of 'A Standardized Pathology Report for Gastric Cancer' was initiated by the Gastrointestinal Pathology Study Group of the Korean Society of Pathologists and published 17 years ago. Since then, significant advances have been made in the pathologic diagnosis, molecular genetics, and management of gastric cancer (GC). To reflect those changes, a committee for publishing a second edition of the report was formed within the Gastrointestinal Pathology Study Group of the Korean Society of Pathologists. This second edition consists of two parts: standard data elements and conditional data elements. The standard data elements contain the basic pathologic findings and items necessary to predict the prognosis of GC patients, and they are adequate for routine surgical pathology service. Other diagnostic and prognostic factors relevant to adjuvant therapy, including molecular biomarkers, are classified as conditional data elements to allow each pathologist to selectively choose items appropriate to the environment in their institution. We trust that the standardized pathology report will be helpful for GC diagnosis and facilitate large-scale multidisciplinary collaborative studies.

Extranodal intraoral Hodgkin lymphoma is not common. We report the case of a 78-year-old male patient with ulcer of the mandibular oral mucosa that was not cured for about 3 weeks. In biopsy and histopathologic examination, it was found to be extranodal intraoral Hodgkin lymphoma. Early diagnosis of oral lesions led to early detection of lesions of the opposite neck lymph node in an additional PET-CT scan. We report this case and review relevant literature.

Background: Errors in surgical pathology diagnosis can have serious consequences for the patient. Since the final product of a surgical pathology lab is the report, errors can be picked by reviewing reports of cases. Aim: To determine the frequency and types of error in surgical pathology reports of cases signed out in 2014 in a laboratory in Karachi, Pakistan. Materials and Methods: All surgical pathology reports in which changes were made in the original report after sign out and an amended report was issued were included. Errors included: (1) misinterpretations; (2) missing critical information; (3) erroneous critical information; (4) misidentification; and (5) typographic errors. Results: Errors were identified in 210 cases (0.37%). These comprised 199 formalin fixed specimens and 11 frozen sections. The latter represented 3.8% of a total of 2,170 frozen sections. Of the 11 frozen section errors, 10 were misinterpretations. Of the 199 permanent specimens, 99 (49.7%) were misinterpretations, 65 (32.7%) belonged to missing critical information category, 8 (4%) belonged to erroneous critical information category, 8(4%) were misidentifications, 16(8%) were typographic errors while 3 cases (1.5%) were other errors. Most misinterpretations occurred in the gastro intestinal, liver and pancreato biliary tract (23.2%) and breast (13.1%). Another 87 cases were reviewed on the clinicians' request. However diagnosis after review remained the same as the original diagnosis. In 49 out of these (56.3%), additional workup was performed at the time of the review. Conclusions: Our findings were similar to other published studies. We need to develop documented procedures for timely review of cases to detect errors.

Inflammatory myofibroblastic tumor, histologically characterized by the presence of bland-locking spindle cells and infiltration of chronic inflammatory cells, is extremely rare in the gastric wall. We report a case of gastric inflammatory myofibroblastic tumor In a 27-month-old boy. The fine needle aspiration biopsy from the mass showed loose clusters or scattered spindle cells and inflammatory cells, predominantly of lymphocytes and plasma cells. The spindle cells resembled fibroblasts or myofibroblasts. Differential diagnosis from benign and malignant diseases involving abdominal cavity was discussed.

Adenoid cystic carcinoma arising from the submucosal glands of the trachea and bronchial tree is rare. The histopathology and natural history of bronchial adenoid cystic carcinoma have been well documented, but detailed descriptions of its cytomorphology are few. We report a case of primary bronchial adenoid cystic carcinoma in a 20-year-old female, diagnosed by bronchial brushing cytology. The cytologic specimens showed large clusters of small cells arranged around cystlike spaces containing globular basophilic material.

This study aims to isolate and identify the causal pathogen of tomato bacterial wilt in Egypt. In 2008, tomato plants showing typical symptoms of bacterial wilt disease with no foliar yellowing were observed in Minia, Assiut and Sohag governorates, Egypt. When cut stems of symptomatic plants were submerged in water, whitish ooze was evident and longitudinal sections showed a brown discoloration in the vascular tissues. Bacteria were isolated on triphenyl tetrazolium chloride medium and fifteen isolates shown typical morphological and cultural characteristics were confirmed as Ralstonia solanacearum biovar 2 race 1. Pathogenicity tests showed that all isolates proved to be pathogenic to tomato plants, varied from 52 to 97% wilting. This is the first report of R. solanacearum biovar 2 race 1 causing bacterial wilt in tomato crop in Egypt.

An 11-year-old obese dog was referred for a liver mass. Cytologic examination revealed vacuolated hepatocytes with mild pleomorphism. A partial liver lobectomy was performed. On histopathologic examination, the mass was diagnosed as hepatocellular carcinoma composed of hepatocytes with clear vacuoles. These findings were consistent with clear cell hepatocellular carcinoma (CCHCC). The CCHCC is a rare subtype of hepatocellular carcinoma in dogs, and clinical features are poorly defined. This is the first report on the cytological, histological and clinical aspects of CCHCC, suggesting that obesity and hyperlipidemia are potential risk factors for CCHCC in dogs.

A 13-year-old intact male English Springer Spaniel presented with anorexia. Physical examination revealed a palpable abdominal mass without peripheral lymphadenopathy. Ultrasonography revealed hepatosplenomegaly and a markedly enlarged hepatic lymph node. Fine-needle aspiration of the splenic and nodal lesions revealed atypical round cells admixed with numerous histiocytes. The dog was euthanized owing to deteriorating condition despite a month of chemotherapy with lomustine. Histopathology revealed obliteration of the normal architecture of the liver, spleen, kidney, and hepatic and mesenteric lymph nodes by CD3⁺ neoplastic lymphocytes, accompanied by extensive F4/80⁺ histiocytic infiltration. This report describes a rare presentation of T-cell lymphoma with prominent histiocytic infiltration that may initially be misdiagnosed as histiocytic neoplasia in a dog.
