Abstract
BACKGROUND

Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is a rare and clinically aggressive hematologic malignancy originating from the precursors of plasmacytoid dendritic cells. BPDCN often involves the skin, lymph nodes, and bone marrow, with rapid clinical progression and a poor prognosis. The BPDCN diagnosis is mainly based on the immunophenotype.

CASE SUMMARY

In this paper, we retrospectively analyzed 2 cases of BPDCN. Both patients were elderly males. The lesions manifested as skin masses. Morphological manifestations included diffuse and dense tumor cell infiltration of the dermis and subcutaneous tissues. Immunohistochemistry staining showed that cluster of differentiation CD4, CD56, CD43, and CD123 were positive.

CONCLUSION

In this paper, we retrospectively analyzed 2 cases of BPDCN. Both patients were elderly males. The lesions manifested as skin masses. Morphological manifestations included diffuse and dense tumor cell infiltration of the dermis and subcutaneous tissues. Immunohistochemistry staining showed that cluster of differentiation CD4, CD56, CD43, and CD123 were positive.

Core Tip: Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is a highly malignant tumor of the hematopoietic and lymphoid tissue, which is extremely rare. BPDCN is highly aggressive and often involves the skin, lymph nodes and bone marrow, with rapid clinical progression and a poor prognosis. In this paper, we retrospectively analyzed 2 cases of BPDCN and reviewed their pathological features, immunophenotype, differential diagnosis, treatment and prognosis, with the aim of improving pathologists’understanding of this entity.
