Papulolinear collagenoma: a rare entity in children

Area of Science:

• Dermatology
• Genetics
• Pathology

Background:

• Connective tissue nevi are rare benign skin tumors.
• Collagenomas are a subtype characterized by excessive collagen deposition.
• Papulolinear collagenoma describes a specific morphologic variant.

Observation:

• A case of a young female patient presenting with skin lesions was observed.
• The lesions exhibited a distinct papulolinear distribution.
• Histopathological examination confirmed increased dermal collagen content.

Findings:

• The patient was diagnosed with papulolinear collagenoma.
• This diagnosis aligns with the definition of a dermal hamartoma.
• The case highlights a rare presentation of a connective tissue nevus.

Implications:

• Understanding rare dermatological conditions like papulolinear collagenoma is crucial for accurate diagnosis.
• This case contributes to the limited literature on connective tissue nevi.
• Further research may elucidate the genetic and developmental basis of this condition.
