Cellular Adaptation IV: Dysplasia and Metaplasia01:24

Cellular Adaptation IV: Dysplasia and Metaplasia

37
DysplasiaDysplasia refers to abnormal changes in the size, shape, and organization of mature cells, characterized by pleomorphism, nuclear abnormalities, and increased mitotic activity. It commonly affects epithelial tissues, including the cervix, gastrointestinal tract, respiratory mucosa, and endometrium. Although it may occur alongside hyperplasia, dysplasia is not a true adaptive response but a preneoplastic change with potential to progress to cancer.When confined above the basement...

Skin Cancer01:30

Skin Cancer

5.2K
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: Stratified Epithelium01:29

Classification of Epithelial Tissues: Stratified Epithelium

11.2K
Stratified epithelium consists of several stacked layers of cells. They provide the durability to withstand constant physical and chemical attacks. Stratified epithelium is named after the shape of the most apical layer of cells. Stratified squamous epithelium is the most common type found in the human body. In this tissue, the apical cells are squamous, whereas the basal layer contains either columnar or cuboidal cells. The basal cells divide to form new daughter cells, which gradually become...

Cadherins in Tissue Organization01:19

Cadherins in Tissue Organization

3.5K
The cadherins are a superfamily of cell adhesion molecules comprising over 180 variants, with specific tissues expressing a particular combination of cadherin types. Cadherins generally exhibit homophilic binding; i.e., cadherins on one cell bind to cadherins of the same or closely related type on another cell. Thus, cells of the same type have a specific affinity to bind to each other and sort themselves into clusters to form tissues.

Cancer Cell Migration through Invadopodia01:35

Cancer Cell Migration through Invadopodia

2.4K
Invadosome is a broad category of cell surface structures with proteolytic activity that  degrades the extracellular matrix (ECM). Invadosomes are present in normal cell types, including macrophages, endothelial cells, and neurons, as well as tumor cells. Although the macrophage podosomes and tumor cell invadopodia are classified as invadosomes, they have different structures, molecular pathways, and functions. Podosomes are short structures that last for a few minutes. However,...

Area of Science:

  • Oncology
  • Pathology
  • Pulmonology

Background:

  • Adenosquamous carcinoma is a rare and aggressive subtype of non-small cell lung cancer.
  • Its histogenesis and distinct clinical features remain incompletely understood.
  • The inherent heterogeneity of lung carcinoma contributes to diagnostic uncertainties.

Purpose of the Study:

  • To reappraise the definition and diagnostic criteria for adenosquamous carcinoma.
  • To address current challenges and practical issues in the pathological evaluation of this neoplasm.
  • To clarify the understanding of this aggressive lung cancer subtype.

Main Methods:

  • Literature review and synthesis of existing research.
  • Analysis of diagnostic criteria and histopathologic features.
  • Discussion of clinical and pathological challenges.

Main Results:

  • Persistent uncertainty exists regarding the histogenesis of adenosquamous carcinoma.
  • Heterogeneity within lung carcinoma complicates definitive classification.
  • Current diagnostic criteria require careful reappraisal.

Conclusions:

  • Accurate pathological evaluation is crucial for diagnosing adenosquamous carcinoma.
  • Further research is needed to clarify histogenesis and refine diagnostic criteria.
  • Addressing practical issues in evaluation will improve patient management.
