Abstract:
Sea-blue histiocytosis is a rare disorder seen in patients with lipid metabolic or ceroid storage diseases. Sea-blue histiocytes are ceroid-laden macrophages detectable by May-Giemsa staining. We report a case of a 28-year-old woman diagnosed with Niemann-Pick disease at 2 or 3 years of age. To confirm this diagnosis, we examined her bone marrow, which revealed scattered foci containing aggregates of foamy macrophages. May-Giemsa staining identified blue-staining foamy macrophages, referred to as sea-blue histiocytes. In summary, we report the detection of sea-blue histiocytosis in an adult with Niemann-Pick disease.
Insights
Sea-blue histiocytosis, characterized by ceroid-laden macrophages, is detected in an adult with Niemann-Pick disease. This finding highlights the diagnostic utility of identifying sea-blue histiocytes in rare lipid metabolic disorders.
Area of Science:
- Hematology
- Genetics
- Metabolic Disorders
Background:
- Sea-blue histiocytosis is a rare condition associated with lipid metabolic and ceroid storage diseases.
- Sea-blue histiocytes are macrophages containing ceroid, identifiable through May-Giemsa staining.
Observation:
- A case study of a 28-year-old woman with a history of Niemann-Pick disease diagnosed in early childhood is presented.
- Bone marrow examination revealed foamy macrophages in aggregates.
- May-Giemsa staining confirmed the presence of sea-blue histiocytes.
Findings:
- The study successfully detected sea-blue histiocytosis in an adult patient.
- Niemann-Pick disease was confirmed as the underlying condition in this adult case.
Implications:
- This case underscores the importance of recognizing sea-blue histiocytosis in adult patients with Niemann-Pick disease.
- The findings may aid in the diagnosis and understanding of rare lipid storage disorders.
- May-Giemsa staining remains a valuable tool for identifying sea-blue histiocytes in clinical diagnostics.
