Diagnosis: Verruca vulgaris
A 15-year-old male presents with a six-month history of multiple hyperkeratotic papules on the dorsal surfaces of his fingers, characterized by black dots. The lesions are asymptomatic but have become a source of cosmetic concern for the patient.
A 15-year-old male presents with a six-month history of multiple hyperkeratotic papules on the dorsal surfaces of his fingers, characterized by black dots. On examination, the lesions are firm, raised, and exhibit a rough surface, typical of viral warts. The patient reports no associated pain or itching.Multiple lesions: Numerous raised papules clustered on both hands.Black dots: Characteristic thrombosed capillaries present within the lesions.Firm texture: Lesions are hard to palpation, indicating hyperkeratosis.Asymptomatic: No pain or pruritus reported by the patient.Location: Primarily on the dorsal fingers, with some lesions on the knuckles.
The patient first noticed the lesions approximately six months ago, with gradual progression in number and size. He reports no significant history of trauma or other skin conditions. Previous treatments include over-the-counter salicylic acid preparations, which provided minimal improvement. The patient has no relevant past medical history and lives in a household with multiple siblings, increasing the likelihood of HPV transmission.Onset: Lesions first appeared six months prior and have progressively increased in number.Previous treatments: Salicylic acid preparations used without significant improvement.Family history: No known history of viral warts or other dermatologic conditions.Social history: Lives with siblings, increasing potential exposure to HPV.Trauma history: No significant trauma or prior skin conditions reported.
Acute / First-Line ManagementTopical salicylic acid: Applied daily, starting with concentrations of 17% to 40% to promote exfoliation of the wart tissue.Cryotherapy: Liquid nitrogen applied every 2-3 weeks for 2-3 sessions, leading to wart destruction.Cantharidin: Topical application, followed by occlusion, can be considered for treatment, leading to blister formation and subsequent lesion resolution.Workup and Diagnostic ConfirmationClinical diagnosis: Typically made through physical examination and characteristic appearance of lesions.Histopathology: Not routinely necessary but can confirm diagnosis in atypical cases, revealing koilocytic changes.Long-Term ManagementMonitoring: Regular follow-up appointments to assess treatment response and potential recurrence.Education: Patients should be advised on hygiene practices to prevent transmission and recurrence.Alternative therapies: For recalcitrant cases, consider intralesional bleomycin or immunotherapy with Candida antigen.
Common wart: Characterized by similar hyperkeratotic papules, typically found on the hands and feet; may include black dots from thrombosed capillaries.Plantaris wart: Found on the plantar surface, often tender on pressure; may be confused with calluses.Flat wart: Smaller, smooth papules, usually multiple, more common in children and adolescents.Seborrheic keratosis: Usually presents as a stuck-on appearance, typically seen in older adults, and lacks the characteristic black dots.Actinic keratosis: Rough, scaly patches in sun-exposed areas, typically in older adults, and may progress to squamous cell carcinoma.Acrochordon: Soft, pedunculated lesions commonly found in skin folds, differing in texture and appearance.Keratoacanthoma: Rapidly growing nodules resembling squamous cell carcinoma; typically solitary and often require biopsy for diagnosis.Basal cell carcinoma: May present as a pearly papule with telangiectasia; more common in sun-exposed areas.
High-Yield PearlsViral etiology: Caused by human papillomavirus (HPV), commonly affecting children and young adults.Transmission: Spread through direct contact and can occur in communal settings, such as swimming pools.Diagnosis: Primarily clinical; characteristic appearance and symptoms are usually sufficient for diagnosis.Treatment options: Include topical therapies, cryotherapy, and procedural interventions; effectiveness varies by individual.Recurrence: Common; patients should be educated on preventive measures and potential need for repeat treatments.Verrucae vulgaris are benign epidermal tumors caused by HPV, often resolving spontaneously but may require intervention for symptomatic or cosmetic concerns.
