Summary
Sinus histiocytosis with massive lymphadenitis (Rosai-Dorfman disease) is a rare condition. This report details an unusual case of skin and eye involvement without lymph node disease, a presentation not previously documented.
Area of Science:
- Dermatology
- Ophthalmology
- Pathology
Background:
- Sinus histiocytosis with massive lymphadenitis, also known as Rosai-Dorfman disease (RDD), is a rare benign histiocytic proliferative disorder.
- While typically affecting lymph nodes, RDD can manifest extranodally, with the skin being the most common site.
- Ocular involvement is infrequent and usually confined to the eyelids.
Observation:
- This case study presents an unusual instance of RDD in a young girl with purely cutaneous lesions.
- The patient exhibited bilateral uveitis, indicating ocular involvement.
- Notably, there was no evidence of lymph node involvement in this case.
Findings:
- The presented case is the first documented instance of concurrent cutaneous and ocular Rosai-Dorfman disease occurring in the absence of lymphadenopathy.
- This finding expands the spectrum of RDD presentations.
Implications:
- This case highlights the importance of considering RDD in the differential diagnosis of unexplained cutaneous and ocular inflammatory conditions, even without typical lymph node enlargement.
- Further research may elucidate the specific mechanisms driving extranodal RDD presentations.
- Recognizing this rare variant is crucial for accurate diagnosis and appropriate patient management.
