Tonsillar actinomycosis: a clinicopathological study

Area of Science:

• Otolaryngology
• Infectious Diseases
• Pathology

Background:

• Actinomycosis is a bacterial infection with a broad range of potential anatomic sites.
• While found in resected tonsils, its role in adeno-tonsillar disease remains understudied.
• Adeno-tonsillar hypertrophy and recurrent tonsillitis are common conditions requiring clinical attention.

Purpose of the Study:

• To investigate the prevalence and clinical associations of actinomycosis in patients undergoing adeno-tonsillar surgery.
• To explore potential links between tonsillar actinomycosis and specific medical conditions.
• To elucidate the etiopathologic role of actinomycosis in adeno-tonsillar hypertrophy.

Main Methods:

• A clinicopathological study was conducted on 302 patients who underwent adeno-tonsillar surgery.
• Tonsillar tissue samples were analyzed for the presence of actinomycosis.
• Statistical analysis was performed to identify significant associations between actinomycosis and clinical factors.

Main Results:

• Actinomycosis was detected in 86 (28.5%) of the patients studied.
• A significant association was found between tonsillar actinomycosis and tonsillar hypertrophy (56.8% vs. 10.3% in recurrent tonsillitis).
• New significant associations were observed between tonsillar actinomycosis and sickle cell anaemia, beta thalassaemia, bronchial asthma, and beta-hemolytic streptococcal infections.

Conclusions:

• Tonsillar actinomycosis is prevalent and significantly associated with tonsillar hypertrophy.
• Conditions such as sickle cell anaemia, beta thalassaemia, and bronchial asthma may predispose individuals to tonsillar actinomycosis.
• Actinomycosis may play a role in the pathogenesis of adeno-tonsillar hypertrophy and related diseases.
