[Cutaneous myofibroma--late manifestations]

Area of Science:

• Dermatology
• Pathology
• Oncology

Background:

• Infantile myofibromatosis is a recognized condition, typically presenting in newborns.
• Solitary lesions are more common than multiple lesions in infantile myofibromatosis.

Observation:

• A case report details a 17-year-old female with a tumor resembling basal cell epithelioma.
• This tumor appeared unusually late, not presenting until adolescence.

Findings:

• Histologically, the tumor in the 17-year-old was indistinguishable from infantile myofibroma.
• The late onset of this lesion led to the proposal of the term "cutaneous myofibroma".

Implications:

• The diagnosis of cutaneous myofibroma should be considered in young patients presenting with basal cell epithelioma-like lesions.
• This case expands the known presentation spectrum of myofibroma-related tumors.
