Skin Cancer

Skin Cancer

Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.
Basal Cell Carcinoma (BCC): BCC is the most common type of skin cancer, accounting for about 80% of cases. It typically develops in...

Classification of Epithelial Tissues: Overview

Classification of Epithelial Tissues: Overview

Epithelial tissues are classified according to the shape of the cells and the number of cell layers formed. Cell shapes can be squamous (flattened and thin), cuboidal (square-like, as wide as it is tall), or columnar (rectangular, taller than it is wide). Additionally, the nucleus shape helps identify the type of epithelial cells. Squamous cells have flattened disc-shaped nuclei, cuboidal cells have spherical nuclei, and columnar cells have elongated nuclei.
Based on the number of cell layers,...

Pulmonary Tuberculosis III

Pulmonary Tuberculosis III

Tuberculosis (TB) is a contagious infection primarily affecting the lung parenchyma but which can also affect other body parts. TB can be classified based on disease development, presentation, and the affected anatomical site.
The first classification is based on the development of the disease, and it includes the following categories:

Primary Lymphoid Organs

Primary Lymphoid Organs

Primary lymphoid organs are pivotal in the formation, development, and maturation of lymphocytes, the white blood cells that serve as the backbone of our immune system. This crucial function underscores their fundamental role in maintaining our overall health and immunity. The two primary lymphoid organs of prime importance are the red bone marrow and the thymus.
The red bone marrow is a soft, spongy tissue nestled in the interior of long bones such as the humerus and femur. It is the site...

Skin Diseases and Disorders

Skin Diseases and Disorders

Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

Classification of Leukocytes

Classification of Leukocytes

Leukocytes are classified into two groups based on the presence or absence of cytoplasmic granules. Granular leukocytes, which contain granules, belong to the myeloid lineage and are divided into three subtypes: neutrophils, eosinophils, and basophils. These cells are roughly spherical and characterized by the granules in their cytoplasm.
Neutrophils are the most abundant type of granular leukocytes, comprising 50-70% of all leukocytes. They feature small, evenly distributed granules and a...

Area of Science:

Dermatology and Hematology
Oncology
Pathology

Background:

Cutaneous lymphomas require standardized classification for accurate diagnosis and treatment.
Previous classifications lacked comprehensive inclusion of all primary cutaneous lymphoma entities.
The World Health Organization/European Organization for Research and Treatment of Cancer (WHO/EORTC) and subsequent WHO classifications established widely accepted standards.

Purpose of the Study:

To review the evolution and conceptual underpinnings of cutaneous lymphoma classifications.
To present the entities, definitions, and diagnostic criteria within the WHO/EORTC and WHO classifications.
To discuss recent updates, clinical implications, and future directions in cutaneous lymphoma classification.

Main Methods:

Literature review focusing on the historical development and conceptual frameworks of lymphoma classification.
Analysis of diagnostic criteria, including clinical, histological, immunophenotypic, and genetic features.
Examination of changes in terminology, staging, and practical applications.

Main Results:

The WHO/EORTC and WHO classifications represent landmark achievements in standardizing cutaneous lymphoma diagnosis.
These systems define distinct disease entities based on integrated clinicopathological, immunophenotypic, and genetic data.
The review outlines specific entities and their diagnostic criteria, emphasizing clinicopathological correlation.

Conclusions:

Accurate classification of cutaneous lymphomas is crucial for effective patient management.
The WHO classifications provide a robust framework for diagnosing primary cutaneous lymphomas.
Ongoing updates and future research are essential for refining diagnostic approaches and understanding these malignancies.
