Progressive Flat Papules on the Extremities: Epidermodysplasia Verruciformis

Area of Science:

• Dermatology
• Medical Missions

Background:

• A US military medical mission provided an opportunity to diagnose a rare skin condition.
• The patient, a 32-year-old woman with Fitzpatrick skin type IV, presented with a chief complaint of numerous white spots on her arms and legs.

Observation:

• The lesions were first noticed 25 years prior and had continuously increased in number.
• The patient reported no family history of similar lesions and was otherwise healthy.
• Examination revealed numerous 3- to 5-mm, well-circumscribed, hypopigmented macules and flat papules on all four extremities.

Findings:

• The case describes a chronic, progressive, and asymptomatic presentation of hypopigmented macules and papules.
• The distribution was limited to the extremities, with no other skin findings.
• This presentation is consistent with a rare, idiopathic dermatosis.

Implications:

• This case underscores the importance of thorough dermatological evaluation, even in resource-limited settings.
• Further investigation may be warranted to determine the exact etiology and optimal management of such chronic hypopigmented conditions.
• Understanding rare dermatoses encountered during medical missions can improve global health awareness.
