Segmental distribution of nodules on trunk.

Area of Science:

• Dermatology
• Pathology

Background:

• This case highlights a rare dermatological condition characterized by numerous, persistent skin papules.
• The patient, a 70-year-old male, reported the onset of lesions at age 28, with gradual increase in size and number.

Observation:

• Numerous, nontender, fleshy, skin-colored papules (3-8 mm) were observed on the trunk.
• Incidental finding during examination for unrelated nonhealing cheek lesions.
• Patient's son had a similar lesion, suggesting a possible genetic component, though no other family history was reported.

Findings:

• A biopsy of a nodule was performed for definitive diagnosis.
• The clinical presentation suggests a benign neoplastic or hamartomatous process.

Implications:

• Accurate diagnosis is crucial for appropriate management and patient reassurance.
• Understanding the etiology may guide future treatment strategies for similar cases.
• This case underscores the importance of thorough dermatological examination for incidental findings.
