Summary
This case study details an unusual adult Letterer-Siwe disease (LSD) presentation in a 71-year-old woman. Despite initial response to topical therapy, the histiocytosis X (HX) rapidly disseminated, proving fatal.
Area of Science:
- Hematology
- Dermatology
- Oncology
Background:
- Histiocytosis X (HX) is a rare histiocytic proliferation disorder with diverse clinical presentations.
- Letterer-Siwe disease (LSD) is a subacute disseminated form of HX, typically affecting infants but rarely seen in adults.
Observation:
- An unusual case of LSD in a 71-year-old woman with a 3-year history of splenomegaly preceding skin lesions.
- Diagnosis of HX was confirmed via skin biopsy.
- Initial treatment with topical nitrogen mustard (NM) achieved complete remission of cutaneous lesions.
Findings:
- The patient experienced a rapid and fatal systemic dissemination of HX after 10 months of stability.
- Systemic therapies including prednisone, vinblastine sulphate, and suppressin A (SA) were ineffective in controlling the disseminated disease.
- Histopathologic, immunohistochemical, and electron microscopic findings characteristic of HX were documented.
Implications:
- This case highlights the potential for rare adult presentations of LSD and the challenges in managing disseminated HX.
- The ineffectiveness of systemic treatments underscores the need for further research into novel therapeutic strategies for adult LSD.
- Reviewing adult LSD cases and treatment options is crucial for improving patient outcomes in this rare condition.
