[Pseudotumorous gout in a 34-year-old man]

Area of Science:

• Rheumatology
• Orthopedics
• Dermatology

Background:

• Gout is a common inflammatory arthritis characterized by hyperuricemia and urate crystal deposition.
• Atypical presentations of gout, such as tumor-like tophi, can pose diagnostic challenges.

Observation:

• A young male patient presented with multiple, prominent, tumor-like tophi.
• One large tophus was situated near the right knee joint, significantly restricting its range of motion.

Findings:

• The case highlights an unusual manifestation of gout with significant external physical impact.
• Surgical intervention was required to address the mechanical obstruction caused by the tophus.

Implications:

• This case underscores the importance of considering atypical gout in differential diagnoses for tumorous masses, especially near joints.
• Early recognition and management of gouty tophi are crucial to prevent joint damage and functional impairment.
