Summary
This case study details a rare multisystemic disease, multicentric reticulohistiocytosis, presenting with joint and skin lesions. Combination therapy showed significant improvement in the patient's symptoms.
Area of Science:
- Rheumatology
- Dermatology
- Pathology
Background:
- Multicentric reticulohistiocytosis is a rare, systemic non-Langerhans cell histiocytosis.
- It is characterized by destructive arthritis and characteristic skin and mucosal lesions.
Observation:
- A 33-year-old woman presented with rheumatoid arthritis-like joint changes and papulonodules.
- Cutaneous lesions evolved, followed by dyspnea and a husky voice.
- Biopsies revealed multinucleated giant cells with eosinophilic cytoplasm, consistent with multicentric reticulohistiocytosis.
Findings:
- Bronchoscopy showed bronchial nodules, and laryngoscopy revealed a laryngeal mass.
- Imaging indicated pleural effusion, pericardiac effusion, splenomegaly, and peritoneal fluid.
- Histopathological examination confirmed multicentric reticulohistiocytosis.
Implications:
- Combination therapy with prednisone, cyclophosphamide, and methotrexate led to significant improvement in cutaneous and joint symptoms.
- This case highlights the extensive systemic involvement possible in multicentric reticulohistiocytosis.
- Early diagnosis and multidisciplinary management are crucial for patients with this rare condition.
