Dyskeratosis congenita in Adult
The condition also may cause lacrimal duct atresia with excessive tearing, and bone marrow failure with consequent anemia, thrombocytopenia, or pancytopenia. Hyperhidrosis of palms and soles, blister formation, acrocyanosis, hair loss (scalp), and early tooth loss also occur.
Pneumonia and sinusitis, likely due to defective humoral immune system (dysgammaglobulinemias), are common. Suppression of cellular immunity is evidenced by opportunistic infections with Pneumocystis pneumonia and cytomegalovirus. Pancytopenia, Fanconi type, is a possible complication. Death by the third decade from bone marrow failure, infection, malignancy (squamous cell cancer, usually of mucous membranes, acute myelogenous leukemia, or Hodgkin disease), pulmonary fibrosis, or liver cirrhosis is a frequent occurrence.
Dyskeratosis congenita has an X-linked recessive inheritance, most frequently, or may be inherited in an autosomal recessive or dominant fashion.
