Dyskeratosis congenita: presentation of cutaneous triad in a sporadic case.

Dyskeratosis congenita (DKC) also known as Zinsser-Cole-Engman syndrome is a progressive genetic disease with a classical presentation characterised by a triad of reticulate pigmentation of skin, nail dystrophy and leukoplakia. It may be a multisystem disease with the involvement of haematological, gastrointestinal, genitourinary, neurological, ophthalmic, pulmonary and skeletal system. We report a sporadic case of DKC presenting with poikiloderma, nail dystrophy and oral leukoplakia.
