Post-aural Nodular Fasciitis

Area of Science:

• Pathology
• Oncology
• Dermatology

Background:

• Nodular fasciitis is a rare, benign soft tissue proliferation.
• Distinguishing it from other neoplastic lesions can be challenging.
• Accurate diagnosis is crucial for appropriate patient management.

Observation:

• An 18-year-old male presented with a firm, immobile post-auricular mass.
• Radiology indicated a subcutaneous mass with specific density characteristics.
• Initial fine-needle aspiration cytology (FNAC) misdiagnosed the lesion as pleomorphic adenoma.

Findings:

• Histopathological examination confirmed the diagnosis of nodular fasciitis.
• The case highlights a potential pitfall in FNAC interpretation for post-auricular masses.
• Unusual locations of suspected pleomorphic adenoma warrant consideration of nodular fasciitis.

Implications:

• This case underscores the importance of integrating clinical, radiological, and pathological findings.
• Awareness of nodular fasciitis in unusual locations can prevent misdiagnosis.
• Accurate diagnosis of benign lesions like nodular fasciitis avoids unnecessary aggressive treatment.
