Dermatologists should be vigilant in diagnosing DKC, especially in young patients without typical features. Early diagnosis allows for effective treatment and management through skin cancer monitoring, sun protection measures, and, if necessary, bone marrow transplantation.
Dyskeratosis congenita (DKC) is a genodermatosis of variable inheritance and is often characterised by the classical triad of nail dysplasia, reticulate hyperpigmentation of upper chest and neck, and oral leukoplakia. We report 2 cases of DKC from National University Hospital, Singapore, whose clinical presentations differed greatly from each other. Dermatologists should hold a high index of suspicion for DKC in young patients who present without the classical triad of features, as early dermatological care can be instituted through reinforcement of rigorous sun protection and regular surveillance for skin cancers. Early diagnosis also offers physicians the time to organise haematopoietic stem cell transplantation if necessary, as bone marrow failure is often inevitable. As a multisystemic disease with high morbidity and mortality particularly from haematological complications if left undetected and untreated in the early stages, the role of the dermatologist in diagnosing DKC is a crucial one.
