Warty dyskeratoma
Learn about Warty dyskeratoma, its reported features, relevant specialists, and questions to discuss at a medical consultation.
Also known as: Follicular dyskeratoma
The sources compiled here do not cover: diagnosis, treatment, prevention, prognosis, prevalence. Ask the treating doctor about these.
What it is
From: Orphanet
A rare, benign, epidermal disease characterized by a solitary, asymptomatic, verrucous, skin-coloured to red-brown papule or nodule, which contains a central pore and keratotic plug, occuring most frequently on the scalp, face and neck (rarely, in the mouth, under the nail plate or on the mons pubis). Occasionally, lesions may be multiple and/or pruritic. Histologically, a well-circumscribed, cup-shaped, keratin-filled invagination, with prominent acantholytic dyskeratosis, suprabasilar clefts and villi projecting into the clefts, is observed.
Reported clinical features and what the terms mean
The following findings are associated with this condition in Orphanet. They are not a checklist for diagnosing yourself, and they do not all occur in every affected person. Some are examination, imaging or laboratory findings that cannot be recognised at home.
The frequency labels describe how often a finding was reported among people with the condition in the source. They do not give the chance that a person with that symptom has the condition. Definitions below reproduce HPO terminology; they explain the term, not the likely severity in an individual.
- Abnormal perifollicular morphology · Very frequent (99-80%)
- Any structural anomaly in the areas surrounding the hair follicles.
- Acantholysis · Very frequent (99-80%)
- The loss of intercellular connections, such as desmosomes, resulting in loss of cohesion between keratinocytes.
- Epidermal thickening · Very frequent (99-80%)
- Thickening of the epidermal layer of the skin.
- Localized skin lesion · Very frequent (99-80%)
- A lesion of the skin that is located in a specific region rather than being generalized.
- Abnormality of the neck · Frequent (79-30%)
- An abnormality of the neck.
- Abnormality of the scalp · Frequent (79-30%)
- Any anomaly of the scalp, the skin an subcutaneous tissue of the head on which head hair grows.
- Acrokeratosis · Frequent (79-30%)
- Overgrowth of the stratum corneum characterized by flesh-coloured or slightly pigmented smooth or warty papules on the upper surface of hands and feet.
- Erythematous papule · Frequent (79-30%)
- A circumscribed, solid elevation of skin with no visible fluid that is reddish (erythematous) in color.
- Skin-colored papule · Frequent (79-30%)
- A papule with the same color as the surrounding skin.
- Umbilicated nodule · Frequent (79-30%)
- A type of skin nodule that has a small depression that resembles a navel (i.e., is umbilicated).
- Focal epithelial hyperplasia of oral mucosa · Occasional (29-5%)
- The occurrence of multiple or unique whitish or normal in color small papules or nodules in oral cavity, especially on labial and buccal mucosa, lower lip and tongue, and less often on the upper lip, gingiva and palate.
- Oral mucosa nodule · Occasional (29-5%)
- A palpable, solid lesion greater than 5mm in diameter that is located in the mucosa of the mouth.
- Abnormal bleeding · Very rare (<4-1%)
- An abnormal susceptibility to bleeding, often referred to as a bleeding diathesis. A bleeding diathesis may be related to vascular, platelet and coagulation defects.
- Abnormal fingernail morphology · Very rare (<4-1%)
- An abnormality of the fingernails.

Which doctor should you see?
The suggested department for discussing Warty dyskeratoma is Dermatology, with a dermatologist as the relevant type of clinician. Dermatologist; paediatric services for children as appropriate.
This is an editorial referral starting point. The appropriate clinic depends on the person’s age, symptoms, previous diagnosis and local services. The first clinician can decide whether another specialty or a team is needed; a department label does not confirm the diagnosis.
How to prepare for an assessment
Bring a short timeline of the main symptoms: when they first appeared, whether they are constant or episodic, what seems to change them, and how they affect daily activities. Include previous reports, discharge summaries, current medicines and supplements, allergies, and any relevant family history. A dated record is more useful than trying to match every feature in an online article.
Ask the clinician what is already established and what remains uncertain. If a test is suggested, ask what question it answers, what its limitations are and how the result would change the next step. The information here is not an instruction to arrange every possible test. In children, bring growth, developmental and school information if it is relevant to the concern.
- Which features of the skin, hair or nails distinguish the possibilities?
- Would photographs over time help document the changes?
- What should be expected from treatment, and how will irritation or other adverse effects be managed?
Treatment discussions and follow-up
The material gathered for this draft does not provide a complete condition-specific treatment pathway for Warty dyskeratoma. That gap does not mean that treatment is unavailable. A clinician needs to establish the diagnosis and review current guidance before recommending medicines, procedures, rehabilitation or other support.
Before leaving the appointment, clarify the next review date, who will communicate results, and whom to contact if the situation changes. Discuss difficulties with sleep, work, school, mobility, eating or emotional wellbeing when these are relevant. Practical support may require coordination between the treating clinician and other services.
The collected references do not establish a complete prevention or long-term outlook section for this entry. Missing information should not be interpreted as proof that prevention is impossible or that a particular outcome is inevitable. Ask what is known for the exact subtype, stage and personal circumstances, and which uncertainties remain.
When to seek emergency help
Severe breathing difficulty, collapse, new stroke-like symptoms, a seizure that is prolonged or repeated without recovery, uncontrolled major bleeding, or an immediate risk of self-harm require emergency help. In India, call 112 or reach the nearest emergency department. This is a general, non-exhaustive warning list; it is not a condition-specific triage tool.
This condition is usually assessed by a dermatologist. Every profile shows the doctor’s registration and what has been checked.
