Background: Germline GATA2-deficiency usually manifests as immunodeficiencies and myeloid neoplasms and sometimes with dermatological diseases, including warts, panniculitis, and skin cancers.
Case: We report a 36-year-old woman with germline GATA2-deficiency who developed Merkel cell carcinoma followed by acute myeloid leukemia. Molecular analysis revealed a germline GATA2 S447R variant, not reported from the previous reported case, suggesting a potential association with Merkel cell carcinoma.
Conclusion: This case broadens the spectrum of solid cancers linked to GATA2-deficiency, emphasizing the need for considering primary immunodeficiency in young patients with myeloid neoplasms or rare skin cancers, facilitating early detection and treatments.
Keywords: GATA2‐defieciency; Merkel cell carcinoma; acute myeloid leukemia.
