Gap Analysis Study before Implementation of Thailand’s National Guidelines for Point of Care Testing at Chiang Rai Province
The Bureau of Laboratory Quality Standards has published Thailand’s National Guidelines for Point-of-Care Testing (POCT) since August 2015. Still yet, the implementation of the guidelines is a great challenge....
Rate of Dyserythropoiesis-like Nuclear Changes in Erythroid Precursors in Bone Marrow
Dyserythropoiesis-like post-mortem changes in erythroid precursors at autopsy can look similar to certain kinds of pathologic processes. Objective: This study is to evaluate nuclear changes in erythroid precursors in marrow aspirate smears and histologic sections at different intervals...
Update in Thymoma for Surgical Pathologists
Thymoma is the most common mediastinal tumor in adulthood. By defi nition, it is a thymic epithelial neoplasm that displays at least some characteristics of normal thymus. Microscopically it comprises an admixture of thymic epithelial cells and immature T lymphocytes in various proportions and demonstrates marked intratumoral...
Transformation in Malignant Lymphoma: Morphologic Approach
Morphologic approach is still very crucial to detect transformation in malignant lymphoma. With the knowledge of each malignant lymphoma type, especially the clinical course, a number of lymphoma can have histologic progression as evidence of transformation as follow: large cell transformation, blastic transformation, and histiocytic...
The Many Faces (and Origins) of Adenocarcinoma in the Liver: Pattern Approach to Diagnosis on Small Tissue Samples
Focal liver lesions can be solitary or multiple, solid or cystic, congenital or acquired, and range from cysts, hamartomas, hyperplastic nodules and inflammatory entities to tumors and tumor-like lesions. The background liver may be normal or diseased. An algorithmic approach based on pattern recognition and cell profiling is outlined for the ...
Developing Pathology Services in Resource Poor Settings An Invitation to the International Academy of Pathology Meeting Bangkok 2014
The delivery of high quality laboratory medicine services in developing countries of low economic resources poses particular problems. International efforts to help develop pathology take many forms and include educa- tional and training initiatives by a number of organisations, although these are often disparate. In this article we will...
A practical approach to undifferentiated tumors: A review on helpful markers and common pitfalls
The term “undifferentiated” tumor is commonly used by pathologists when a tumor lacking evidence of lineage differentiation on the basis of routine light microscopic morphology is encountered. Immunohisto- chemistry plays an important role in elucidating the true nature of the undifferentiated tumor that is crucial for clinical management....
Diagnostic Pitfalls of Prostatic Adenocarcinoma in Biopsy Specimens
Prostatic adenocarcioma is a very common male cancer worldwide. Biopsy remains the most reliable means in making definite diagnosis. In the prostate-specific antigen (PSA) screening era, the rate of prostate biopsies rapidly increases, resulting in early detection of very small tumors. In the same time, general pathologists are forced to face...
