Multicentric reticulohistiocytosis in a Malaysian Chinese lady: a case report and review of literature .
A 36-year-old Malaysian woman with erosive arthritis presented with multiple asymptomatic skin colored papulonodules on the hands, elbows, knees, ears, and feet; many macules, papules, and plaques were photodistributed. Progressive, erosive arthritis began about 18 months after the onset of skin involvement. Initially the patient was diagnosed to have dermatomyositis due to her skin findings, but later proved to have multicentric reticulohistiocytosis based on the typical histopathological features of histiocytic multinucleated giant cells with eosinophilic ground glass cytoplasm on skin biopsy. Workup for associated diseases including malignancies was negative. Her skin lesions and joint pain responded to treatment with methotrexate and prednisolone.
