Polymorphic Midline Reticulosis (PMR), also known as Midline Lethal Granuloma or Midline Malignancy, is a rare and aggressive type of non-Hodgkin lymphoma. This cancer primarily affects the mucosal lining in the midline facial and upper respiratory areas, such as the nasal cavity, throat, and palate. PMR is characterized by the presence of diverse cell types and is often difficult to diagnose due to its rarity and varied presentation.

Types of Polymorphic Midline Reticulosis:

1. Localized PMR: This type of PMR is confined to a specific area of the midline region, such as the nose or throat.
2. Systemic PMR: In systemic PMR, the disease has spread to other parts of the body, including lymph nodes and organs.

Causes of Polymorphic Midline Reticulosis:

The exact cause of PMR is not well understood, but several factors may contribute to its development. These include:

1. Viral Infections: Some viral infections, like Epstein-Barr virus (EBV), have been linked to an increased risk of PMR.
2. Genetic Predisposition: There may be a genetic component that makes certain individuals more susceptible to PMR.
3. Environmental Factors: Exposure to certain environmental toxins or allergens could potentially trigger PMR in susceptible individuals.
4. Immune System Dysfunction: An abnormal immune response may play a role in the development of PMR.
5. Autoimmune Disorders: People with autoimmune disorders may be at a higher risk of developing PMR.
6. Chronic Inflammation: Long-term inflammation in the nasal and throat areas may contribute to the development of PMR.
7. Immunodeficiency: Individuals with weakened immune systems may be more prone to PMR.
8. Unknown Factors: In many cases, the specific cause remains unknown.
