Cutaneous Cysts with Nail Dystrophy in a Young Female: A Classical Association.

Pachyonychia Congenita (PC) refers to a group of autosomal dominant disorders with variable clinical presentations. While nail dystrophy and plantar keratoderma are the most consistent features in all the variants, a myriad of other manifestations has been observed. This report highlights a case of young female presenting with multiple asymptomatic cutaneous cysts associated with plantar kearatoderma and nail dystrophy. Similar nail changes were evident in her son also. Such clinical presentation, in corroboration with histopathological evaluation of the cutaneous cyst prompted us to make a diagnosis of Pachyonychia Congenita type II.
