[Benign rheumatoid nodules. Report of 4 cases]

Area of Science:

• Rheumatology
• Dermatopathology

Background:

• Benign rheumatoid nodules (BRNs) are histologically identical to rheumatoid arthritis nodules.
• BRNs typically occur in healthy individuals lacking rheumatic disease manifestations.
• These nodules are more common in children and rare in adults.

Observation:

• The literature documents approximately 200 childhood cases and 25 adult cases of BRNs.
• This report details four new histologically confirmed cases of BRNs.
• Two cases were in children and two were in adults.

Findings:

• The study presents four new histologically proven cases of benign rheumatoid nodules.
• The cases included two children and two adults.
• Histological confirmation was obtained for all reported cases.

Implications:

• The findings support the generally optimistic prognosis for patients with benign rheumatoid nodules.
• This case series contributes to the limited documented adult cases of BRNs.
• Highlights the importance of histological confirmation for accurate diagnosis and prognosis.
