[Lymphoma misinterpreted as osteomyelitis].

Area of Science:

• Internal Medicine
• Oncology
• Diagnostic Radiology

Background:

• Accurate initial diagnosis is crucial for effective patient management and healthcare resource allocation.
• Diagnostic errors can lead to suboptimal treatment, prolonged illness, and increased healthcare costs.

Observation:

• A patient presented with symptoms initially suspected as osteomyelitis, leading to an eight-month diagnostic workup.
• Despite contradictory findings, the initial diagnosis of osteomyelitis was maintained.
• The patient was ultimately diagnosed with peripheral T-cell lymphoma.

Findings:

• Cognitive biases, such as confirmation bias, can significantly impede diagnostic accuracy.
• Persistent adherence to an incorrect tentative diagnosis can delay definitive treatment for the actual underlying condition.
• The case underscores the importance of critically evaluating diagnostic data and considering alternative diagnoses.

Implications:

• Recognizing and mitigating cognitive diagnostic pitfalls is essential for improving patient outcomes.
• Prompt interdisciplinary consultation should be sought when initial treatments for a tentative diagnosis are ineffective.
• This case emphasizes the need for continuous re-evaluation of diagnoses throughout patient care.
