Actinomycosis can mimic carcinoma, leading to misdiagnosis. Two cases highlight the importance of histological confirmation before surgery for thoracic and pelvic-abdominal masses.

Area of Science:

  • Medical Mycology
  • Surgical Pathology
  • Differential Diagnosis

Background:

  • Actinomycosis is a rare bacterial infection often confused with malignant neoplasms.
  • Carcinoma and actinomycosis share overlapping clinical and radiological features, complicating diagnosis.
  • Accurate differentiation is crucial for appropriate patient management and treatment.

Observation:

  • Two distinct cases of actinomycosis are presented: one in the thorax and another in the pelvic-abdominal region.
  • Both cases initially presented with clinical signs suggestive of carcinoma.
  • Patients proceeded to surgical intervention without a definitive preoperative histological diagnosis of actinomycosis.

Findings:

  • Histological examination ultimately confirmed actinomycosis in both cases, revealing the true nature of the disease.

  • The similar presentation of actinomycosis and carcinoma underscores diagnostic challenges.
  • Delayed or missed diagnosis can lead to unnecessary surgical procedures and suboptimal treatment.

    • Implications:

    • Emphasizes the critical need for thorough diagnostic evaluation, including histological confirmation, for suspected thoracic and pelvic-abdominal masses.
    • Highlights the importance of considering actinomycosis in the differential diagnosis of neoplastic-like lesions.
    • Suggests a review of diagnostic protocols to improve the early identification of actinomycosis and prevent misdiagnosis as carcinoma.
