Classification of Epithelial Tissues: Overview01:22

Classification of Epithelial Tissues: Overview

19.3K
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,...

Skin Cancer

5.6K
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...

The Retinoblastoma Gene01:20

The Retinoblastoma Gene

4.5K
Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...

Barrett Esophagus-II: Clinical Manifestations and Management

583
Individuals with Barrett's esophagus are often asymptomatic, but they may experience symptoms commonly associated with GERD, such as heartburn and acid regurgitation. Additional symptoms can include difficulty swallowing, chest pain, unintentional weight loss, blood in the stool (which may appear black, tarry, or bloody), and episodes of vomiting.
To diagnose Barrett's esophagus, healthcare providers often recommend an endoscopy for those showing symptoms of acid reflux. The procedure...

Summary

Epithelioid sarcoma (ES) is an aggressive soft tissue cancer often affecting young adults. While surgery and radiotherapy are key for localized disease, advanced stages require chemotherapy, with novel therapies like tazemetostat showing promise.

Area of Science:

  • Oncology
  • Pathology
  • Genetics

Background:

  • Epithelioid sarcoma (ES) is a rare mesenchymal soft tissue sarcoma.
  • It typically affects young adults, with a peak incidence around 35 years.
  • ES is characterized by the loss of SMARCB1/INI1 or other SWI/SNF complex proteins.

Purpose of the Study:

  • To summarize the current understanding of epithelioid sarcoma.
  • To outline diagnostic and therapeutic strategies for ES.
  • To highlight the need for novel treatment approaches.

Main Methods:

  • Review of existing literature on epithelioid sarcoma.
  • Analysis of clinical presentation, molecular characteristics, and treatment outcomes.
  • Evaluation of current and emerging therapeutic options.

Main Results:

  • Two distinct types, proximal and distal, exhibit varying biology and outcomes.
  • Aggressive behavior includes high recurrence rates and lymph node metastasis.
  • Localized ES management involves wide surgical resection, potentially with radiotherapy.
  • Sentinel lymph node biopsy is recommended.
  • Metastatic ES has a poor prognosis (median survival ~1 year).
  • Doxorubicin-based regimens are standard for advanced disease.
  • Tazemetostat shows promise in clinical trials.

Conclusions:

  • Optimal long-term management strategies for ES are still evolving.
  • Multidisciplinary approaches are crucial for effective treatment.
  • Further research into novel therapies, including immunotherapy, is essential for improving patient outcomes.
