Abstract:
Non-Hodgkin lymphoma (NHL) comprise 7-10% of all malignant tumors in childhood. Early systems of classification (Rappaport, Luke-Collins) have been improved with the Working Formulation. NHL are classified into low, intermediate and high-grade disease. Head and neck manifestations of Burkitt's lymphoma are encountered in less than a quarter of the reported cases and usually present as cervical adenopathy. Parapharyngeal space and extranodal disease are unusual sites of involvement. We present a case of tonsillar lymphoma diagnosed with fine-needle biopsy and confirmed with excisional biopsy. Accurate staging (stage IV) and chemotherapy regimen was promptly begun. We review the clinical aspects, pathologic features and treatment of this disease.

Pharynx
Nasopharynx
The nasopharynx, bordered by the conchae of the nasal cavity, serves exclusively as an air conduit. In its superior region, the pharyngeal tonsils or adenoids are located. These tonsils are clusters of lymphoid reticular tissue akin to a lymph node. The precise...
Lymphoid Cells and Tissues
Lymphoid cells consist of various types of immune system cells. These include B and T lymphocytes, which are responsible for producing antibodies and killing infected cells, respectively. Dendritic cells act as messengers between the innate and adaptive...
Chronic Pharyngitis
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...
Tonsillitis II: Management
Pulmonary Tuberculosis I
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.

Pulmonary Tuberculosis II
Here is a detailed explanation of its pathophysiology:
Transmission: The process begins when a person inhales droplet nuclei containing M. tuberculosis. These are typically released into the air when an individual with pulmonary or...
