Leukemia cutis. A histopathologic study of 42 cases
The American Journal of Dermatopathology
|April 1, 1985
Summary
Skin biopsy analysis in leukemia cutis reveals variable histopathologic changes. Definitive leukemia typing requires peripheral blood or bone marrow examination, not solely skin biopsy findings.
Area of Science:
- Dermatology
- Hematology
- Pathology
Background:
- Leukemia cutis, a manifestation of leukemia in the skin, presents diverse histopathologic features.
- Understanding these variations is crucial for accurate diagnosis and patient management.
Purpose of the Study:
- To analyze the histopathologic characteristics of skin biopsy specimens in patients with leukemia cutis.
- To evaluate the utility of skin biopsy in differentiating various types of leukemia.
Main Methods:
- Histopathologic and histochemical examination of skin biopsy specimens from 42 leukemia cutis patients.
- Classification of leukemia based on peripheral blood and bone marrow findings.
Main Results:
- Leukemia cutis typically shows diffuse leukemic cell infiltration in the dermis and subcutaneous tissue.
- Specific findings like vascular and adnexal involvement were noted in granulocytic, monocytic, and myelomonocytic types.
- Significant variability in histopathologic changes was observed across different leukemia types and even within the same type.
Conclusions:
- Skin biopsy findings in leukemia cutis are highly variable.
- Accurate leukemia typing necessitates integration of morphologic and histochemical studies of peripheral blood and/or bone marrow smears alongside skin biopsy analysis.
