Facial paediatric desmoid fibromatosis: a case series, literature review and management algorithm

Infantile fibromatosis of the mandible- Is radical treatment justified?

Infantile fibromatosis is characterized by proliferation of fibrous soft tissue with a potential of invading the adjacent structures but lacks the ability to metastasize, thus making it a fairly benign lesion with borderline characteristics. The pathology resembles sarcomatous growth, therefore making it difficult for the clinician to correctly diagnose. There are two variants of extra-abdominal desmoid juvenile and adult variant depending upon the age group it predominately involves. Fibromatosis is comparatively a rare tumour with unpredictable growth and varying local recurrence rates. The mass usually grows slowly, rapid growth and recurrences being mostly associated with the juvenile forms. The disease may present as single or multifocal lesion with widespread distribution, thus requiring whole body scans to identify any insidious growth elsewhere. Here, we report a case of recurrent juvenile/infantile fibromatosis in a 2-year-old child, conservatively managed without any growth disturbance and signs of recurrence.

Massive congenital cervicofacial desmoid-type fibromatosis in a 5-month-old infant

Desmoid-type fibromatosis (DF) is a borderline tumor of soft tissues that has low malignant potential but described as infiltrative, locally aggressive and rapidly growing. In the pediatric population, it occurs in the head and neck. Presentation varies based on tumor size and location. Despite the high recurrence rate, surgical excision remains the modality of choice with. Here, we report a case of a 5-month-old boy, with extensive head and neck DF that was managed twice with conservative debulking surgery through a combined transoral-transcervical approach. On 2-year follow-up, he was gaining weight with no developmental delay and had no clinical evidence tumor regrowth.

Orbital Desmoid-Type Fibromatosis: A Case Report and Literature Review

Purpose

Desmoid-type fibromatosis is a benign fibrous neoplasia originating from connective tissue, fascial planes, and musculoaponeurotic structures of the muscles. Currently, there is no evidence-based treatment approach available for desmoid fibromatosis. In this article, a case of a patient in the pediatric age affected by desmoid fibromatosis localized in the orbit is presented. The aim of the article is to describe this unusual and rare location for the desmoid fibromatosis and outline the principle phases in the decision-making process and the therapeutic alternatives for a patient affected by desmoid fibromatosis.

Methods

The protocol of this review included study objectives, search strategy, and selection criteria. The primary end point of this study was to analyze the head and neck desmoid fibromatosis. The secondary end point was to identify the available therapies and assess their specific indications.

Results

The mean age of patients was 18.9 years ranging from 0 to 66, and 52% were female. A bimodal age distribution was observed, and two age peaks were identified: 0–14 years (57%) and 28–42 years (18%). The most common involved areas were the mandible (25%) followed by the neck (21%). In 86% of the cases, the treatment was the surgical resection of the disease, and only in 5% of the cases, the surgical resection was followed by adjuvant radiotherapy.

Conclusion

The orbital location is extremely rare, especially in the pediatric population. The management of desmoid fibromatosis is based on the function preservation and the maintenance of a good quality of life, but in case of symptomatic patients or aggressive course of the disease or risk of functional damages, the surgical approach may be considered. Therapeutic alternatives to surgical resection are radiotherapy and systemic therapy.
