Hamartochondroma arising from a tracheal bronchus.

Area of Science:

• Pulmonology
• Thoracic Surgery
• Congenital Abnormalities

Background:

• Tracheal bronchus is a rare congenital respiratory tract abnormality.
• It is typically asymptomatic but can be associated with inflammatory diseases or, exceptionally, malignancy.
• This case explores a rare association with a benign tumor.

Observation:

• A 45-year-old male presented with a 3-month history of non-productive cough and chest pain.
• Imaging revealed a solitary pulmonary nodule in conjunction with a tracheal bronchus.
• The patient underwent video-assisted thoracoscopic surgery (VATS) for nodule enucleation.

Findings:

• Histopathological examination confirmed the solitary pulmonary nodule as a hamartochondroma.
• This represents the first documented case of a hamartochondroma associated with a tracheal bronchus.
• The patient's symptoms were attributed to this rare combination.

Implications:

• Highlights the importance of considering rare associations in congenital abnormalities.
• Suggests that hamartochondromas may occur in association with tracheal bronchus.
• Contributes to the limited literature on tracheal bronchus complications and associated pathologies.
