Cirrhosis I: Introduction

Cirrhosis is a chronic, irreversible liver disease characterized by the widespread replacement of healthy liver tissue with fibrotic scar tissue and the formation of regenerative nodules.Etiology of cirrhosisCirrhosis results from sustained liver injury that triggers progressive fibrosis and structural remodeling. The underlying causes are diverse, encompassing common and less frequent clinical conditions. Regardless of the origin, all causes lead to chronic inflammation, hepatocyte loss, and...
Nephrotic Syndrome I : Introduction01:24

Nephrotic Syndrome I : Introduction

Nephrotic Syndrome is a chronic kidney disorder defined by clinical findings such as severe proteinuria, hypoalbuminemia, hyperlipidemia, and edema. These symptoms result from damage to the glomeruli, the kidney’s filtering units, increasing their permeability to proteins.Definition and Meaning:Proteinuria, defined as the loss of more than 3.5 grams of protein per day in adults, is a crucial feature of nephrotic syndrome. This condition is often accompanied by edema, the accumulation of fluid...

Nodular fasciitis is often misdiagnosed due to its varied appearance. Definitive diagnosis requires immunohistochemical analysis, especially for head and neck masses with nonspecific findings.

Area of Science:

  • Pathology
  • Oncology
  • Head and Neck Surgery

Background:

  • Nodular fasciitis presents with diverse histological features and a pseudosarcomatous appearance, leading to frequent misdiagnosis.
  • Pre-operative, intra-operative, and final pathological analyses are often confounded by the condition's rarity and variable presentation.

Observation:

  • Review of four nodular fasciitis cases revealed initial misdiagnoses based on physical and radiological findings.
  • Imaging suggested parapharyngeal tumors, lymphoma, metastasis, or accessory parotid tumors.
  • Fine needle aspiration and frozen section examinations were inconclusive, often indicating neurogenic tumors or undifferentiated malignancy.

Findings:

  • Nodular fasciitis diagnosis was consistently delayed, requiring permanent section and immunohistological analysis.

  • Spindle-type cells were a common finding in frozen section examinations, contributing to diagnostic challenges.

    • Implications:

    • Consider nodular fasciitis in patients with head or neck masses exhibiting nonspecific investigation results.
    • Appropriate immunohistochemical markers are crucial for accurate final diagnosis of nodular fasciitis.
