Dyskeratosis congenita (DC) is a rare inherited bone marrow failure syndrome caused by defective telomere maintenance. It often presents with mucocutaneous features, cytopenias, and progressive organ involvement, but remains underrecognized in resource-limited settings. We report a 32-year-old Indonesian male of Javanese ethnicity who presented with progressive anemia, thrombocytopenia, and bilateral hip pain. Physical examination revealed long-standing reticulate hyperpigmentation and premature graying. Bone marrow evaluation showed aplastic anemia, requiring periodical packed red cells transfusions. Telomere length testing demonstrated markedly shortened telomeres, and genetic analysis identified a heterozygous TERC mutation (n.269G > C) in both the patient and his mother. The patient also developed avascular necrosis of both hips, requiring bilateral hip replacement. This case highlights the importance of considering telomere biology disorders such as DC in patients with unexplained cytopenias and premature aging features. Early recognition is essential to guide appropriate management and avoid potentially harmful therapies, particularly in resource-limited settings where these conditions may be underrecognized.
