A thoracic benign mesenchymoma in association with hemihypertrophy

Area of Science:

• Thoracic oncology
• Surgical pathology
• Genetics and rare diseases

Background:

• Benign mesenchymomas are rare tumors.
• Hemihypertrophy is a congenital condition characterized by asymmetric overgrowth of body parts.
• Patients with hemihypertrophy have an increased risk of developing various neoplasms.

Observation:

• An 18-year-old male with hemihypertrophy presented with a large thoracic benign mesenchymoma.
• The tumor was composed of mature vascular spaces, adipose tissue, and smooth muscle.
• Surgical excision of the tumor was performed.

Findings:

• The patient experienced no recurrence of the benign mesenchymoma one year post-surgery.
• Histopathological analysis confirmed the benign nature and mixed cellular composition of the tumor.
• No complications were reported following the surgical removal.

Implications:

• This case highlights a rare presentation of benign mesenchymoma in a patient with hemihypertrophy.
• It underscores the importance of lifelong surveillance for individuals with hemihypertrophy due to their predisposition to neoplasms.
• Early detection and management of tumors in this population are crucial for favorable outcomes.
