Surgical implications of actinomycosis.

Area of Science:

• Infectious Diseases
• Surgical Pathology
• Medical Diagnostics

Background:

• Actinomycosis is a rare bacterial infection caused by Actinomyces species.
• Abdominal actinomycosis presents with diverse clinical manifestations, often mimicking other intra-abdominal pathologies.
• Diagnostic challenges arise due to the nonspecific symptoms and the organism's fastidious nature.

Observation:

• Two distinct cases of abdominal actinomycosis are presented.
• Case 1: Extensive intra-abdominal and thoracic actinomycosis mimicking metastatic carcinoma.
• Case 2: Rare retroperitoneal actinomycosis without intra-abdominal involvement.

Findings:

• Both patients demonstrated a positive response to appropriate antibiotic therapy.
• Unnecessary surgical procedures were performed in both cases prior to definitive diagnosis.
• The study highlights the importance of considering actinomycosis in the differential diagnosis of complex abdominal masses.

Implications:

• Accurate and timely diagnosis of actinomycosis is essential to avoid aggressive surgical interventions.
• The role of surgery in actinomycosis should be primarily diagnostic, not therapeutic.
• Increased awareness among clinicians can lead to improved patient outcomes and reduced healthcare costs.
