What is the life expectancy of someone with dyskeratosis congenita?
Life expectancy ranges from infancy to well into the 7th decade. Up to 40% of patients will have BMF by the age of 40. Major causes of morbidity include BMF, cancer and pulmonary complications.
What is the treatment for Darier’s disease?

What is malignant dyskeratosis?
Abstract. Dyskeratosis congenita (DC) is a rare genodermatosis characterised by a classic triad of dystrophic nails, reticular skin pigmentation and mucous membrane leukoplakic patches, which have a high rate of malignant transformation.
What are the symptoms of dyskeratosis congenita?
What are the symptoms of dyskeratosis congenita?
- abnormalities of the skin, such as unusual pigmentation with a net-like pattern on the neck and upper chest.
- defects in fingernails and toenails, including cracking, splitting, and underdevelopment or distortion.

What is keratosis follicularis (Darier disease)?
NORD gratefully acknowledges Dr. Susan Burge, Honorary Consultant Dermatologist, Oxford University Hospitals NHS Trust, United Kingdom, for assistance in the preparation of this report. Keratosis follicularis, also known as Darier disease, is a rare, genetic skin disorder.
How do you treat hyperkeratosis follicularis?
Therapy that helps soften and shed hardened, abnormal skin (keratolytics) such as treatment with salicylic acid in propylene glycol gel may also help treat hyperkeratosis. Topical corticosteroids and substances that soothe and soften the skin (emollients) have also been used to alleviate inflammation in localized keratosis follicularis.
What is the histologic pattern of acantholytic dyskeratosis?
As the histologic pattern is an epidermal reaction pattern of acantholytic dyskeratosis, the differential diagnosis often includes Grover’s disease, Darier’s disease, and acantholytic actinic keratosis or squamous cell carcinoma. Therefore, clinicopathologic correlation is necessary.
What is the pathophysiology of keratosis follicularis?
Keratosis follicularis is a genetic disorder that occurs randomly as the result of a spontaneous genetic change (i.e., new mutation) or the mutation is inherited as an autosomal dominant trait.
