Fibromatosis Colli: About 26 Cases

Area of Science:

• Pediatric Pathology
• Neonatal Care
• Diagnostic Imaging

Background:

• Fibromatosis colli is a rare benign soft tissue tumor affecting newborns and infants.
• It typically presents as a firm mass in the sternocleidomastoid muscle.
• Understanding its epidemiological and clinical features is crucial for appropriate management.

Purpose of the Study:

• To identify the epidemiological, diagnostic, therapeutic, and evolutionary aspects of fibromatosis colli.
• To determine risk factors associated with its occurrence.
• To analyze clinical presentation and treatment outcomes.

Main Methods:

• Retrospective descriptive study of 26 cases of fibromatosis colli.
• Data collected from patient files over three years (2017-2019).
• Parameters included demographics, clinical findings, ultrasound results, treatment, and evolution.

Main Results:

• The condition occurred at a frequency of 6.5 cases/year, with a mean age of 2.1 months.
• Obstetrical trauma (61.5%) and primiparity (57.5%) were common associated factors.
• Cervical ultrasonography confirmed the diagnosis in all cases; surveillance was the primary treatment (84.6%).

Conclusions:

• Fibromatosis colli is a rare condition diagnosed clinically and confirmed by ultrasound.
• Management is straightforward, primarily involving surveillance.
• The condition typically shows spontaneous regression within a few months.
