Summary
A rare skin cancer, agranular CD4+/CD56+ hematodermic neoplasm, presented as a cutaneous form without internal involvement. This case highlights a novel manifestation of aleukemic leukemia cutis.
Area of Science:
- Hematology
- Dermatology
- Oncology
Background:
- Agranular CD4+/CD56+ hematodermic neoplasm, or blastic NK-cell lymphoma, is a distinct entity.
- Characterized by skin tropism, bone marrow involvement, and poor prognosis.
- Commonly expresses T helper CD4 and NK cell marker CD56.
Observation:
- An 86-year-old male presented with hemorrhagic skin lesions on the trunk.
- Skin biopsy confirmed an agranular CD4+/CD56+ hematodermic tumor.
- No internal or bone marrow involvement was detected during an 18-month follow-up.
Findings:
- The case represents a cutaneous form of hematodermic tumor.
- This presentation is considered a novel manifestation of aleukemic leukemia cutis.
- The tumor cells expressed both CD4 and CD56 markers.
Implications:
- Highlights the diverse clinical presentations of hematodermic neoplasms.
- Suggests that cutaneous involvement can occur without systemic disease.
- Emphasizes the importance of skin biopsy in diagnosing rare hematologic malignancies.
