Sonographic Diagnosis of Fibromatosis Colli

Fibromatosis colli is a frequent cause of congenital muscular torticollis, a condition in which the patient suffers from a benign neck mass within the sternocleidomastoid muscle that considerably shortens the length of the affected side. The origin of fibromatosis colli has been linked to traumatic birth, intrauterine malposition, or vascular occlusion. Infants who present with fibromatosis colli often develop congenital muscular torticollis. Torticollis is described as the tilting of the head with the chin angled to the nonaffected side. Because of its low cost, lack of ionizing radiation, and the fact that no sedation is needed, sonography has proven to become the modality of choice when evaluating infants who present with a pediatric neck mass. This article offers a case report, the sonographic appearance, the suspected causes, and applicable research that may prove indispensable in achieving the sonographic diagnosis of fibromatosis colli.

Fibromatosis Colli Presenting as an Infantile Neck Mass: Sonographic Appearances in Two Patients

Fibromatosis colli is rare, but is the most common cause of congenital torticollis. We describe, using two case reports as an example, how this condition can be diagnosed, by careful clinical history taking and using ultrasound as the imaging tool. Prompt detection with ultrasound can avoid more invasive methods of evaluation and treatment, and the variations of sonographic appearances of fibromatosis colli are highlighted.

Infantile fibromatosis of the sternocleidomastoid muscle mimicking muscular torticollis

Infantile fibromatosis is a rare entity in children. Although the cervical region is one of the frequent sites of location for this tumor, the diagnosis may be delayed if it occurs in a usual location for a well-known entity, such as muscular torticollis or fibromatosis colli. The authors present an infant with infantile desmoid fibromatosis of the sternocleidomastoid muscle, which has been considered initially as olive of muscular torticollis.

Fibromatosis colli in both heads of the sternocleidomastoid muscle: sonographic findings

Objective: To describe the sonographic findings of fibromatosis colli if both heads of the sternocleidomastoid muscle are involved. Materials and methods: In a retrospective study nine examinations for fibromatosis colli were collected from 67 sonographic studies of the neck. The examinations were analyzed for involvement of one or both heads of the sternocleidomastoid muscle. Results: Both heads of the sternocleidomastoid muscle were involved in six of nine patients. Conclusion: Involvement of both heads of the sternocleidomastoid muscle seems to be frequent in fibromatosis colli. Knowledge of the sonographic appearance of this condition will facilitate its recognition and will preclude an incorrect diagnosis.

Bilateral sternocleidomastoid tumor of infancy

The sternocleidomastoid tumor of infancy (STOI), also known as fibromatosis colli, presents as a firm well circumscribed mass within the sternocleidomastoid muscle (SCM) in infants of 1–8 weeks of age. Some of these lesions are associated with torticollis, facial and cranial asymmetry. Incidence of STOI is ≈0.4% of live births and usually 90% of the patients will have a good prognosis if therapy is initiated and continued for the appropriate period of time. This paper presents two cases of bilateral involvement of STOI, which is very rare. The bilateral nature of the masses added to the uncertainty of the clinical diagnosis and the unusual features of these cases are discussed.

Diagnosis of fibromatosis colli by fine-needle aspiration.

Fibromatosis colli is a benign disorder presenting as a neck mass in neonates and older children. The differential diagnosis includes malignancies such as rhabdomyosarcoma. Neck masses in ten infants, discovered between the second and sixth week of age, were evaluated by fine-needle aspiration (FNA). The male to female ratio was 7:3. In 8 patients there was good obstetrical history. Six of the 8 patients had a difficult delivery, as indicated by breech presentation or the need for forceps. Diagnostic aspirations were performed between the second to ninth week of age. The major cytologic finding was benign spindle fibroblasts, usually arrayed in clusters. The cells possessed plump, ovoid nuclei. There were also multinucleated cells consistent with degenerating skeletal muscle fibers. Only one case demonstrated significant inflammation. FNA can provide a rapid and reliable diagnosis in fibromatosis colli. There is support for the idea that in this setting, the disorder is related to perinatal muscular trauma.

Fibromatoses: Clinical and pathological features suggestive of recurrence

Background/Purpose: Fibromatoses represent a spectrum of nonneoplastic spindle cell tumors frequently identified in childhood. Although they may be locally aggressive, they do not metastasize. The authors have reviewed their experience of these lesions in an attempt to identify clinical and pathological features suggestive of recurrence. Methods: Clinical records and pathological specimens from 55 cases of fibromatosis diagnosed and treated at British Columbia's Children's Hospital from 1982 to 1995 were reviewed. Results: Thirty boys and 25 girls with ages ranging from 1 month to 14 years were identified. Eighteen tumors (33%) were congenital. Diagnoses were as follows: musculoaponeurotic fibromatosis (n = 27), infantile myofibromatosis (n = 10), Dupuytren-type fibromatosis (n = 7), fibromatosis colli (n = 7), and digital fibroma (n = 4). Clinical follow-up showed a survival rate of 98%. The single mortality occurred in an infant born with an intraabdominal visceral myofibromatosis, which proved unresectable. Fifteen cases recurred (27%), and nine cases (16%) of infantile myofibromatosis spontaneously regressed. All remaining cases were controlled successfully by surgical resection. Conclusions: Clinical features suggestive of recurrence included (1) presentation at greater than 5 years of age, (2) extremity location of disease, and (3) incomplete surgical resection. Pathological features suggestive of recurrence were (1) microscopic evidence of tumor at resection margins, (2) mitotic index of 5 or more per 10 high-power fields, and (3) areas of necrosis and inflammation within the tumor.

Diagnosis of fibromatosis colli by fine needle aspiration (FNA) cytology.

This study presents eight cases of fibromatosis colli accurately diagnosed by FNA cytology. Fibromatosis colli is a rare fibroblastic lesion that manifests in the sternocleidomastoid muscle during the first to second months after birth. The tumours varied in size from 1 to 3 cm and engaged the lower, middle as well as the upper part of the sternocleidomastoid muscle. The FNA cytology smears showed mostly mature fibroblasts in a background of pink granular material and fragments of striated muscle fibres with degeneration. The cytological presentation together with the typical clinical setting will allow a definitive and accurate diagnosis, avoiding surgery.

Fibrous tumours in children: imaging features of a heterogeneous group of disorders.

Fibrous tumours are predominantly soft tissue lesions which are relatively frequent in childhood but are little known. Imaging is often used in the evaluation of these tumours but their characteristics, particularly on US or MRI, have not been studied systematically. To provide an overview of the clinical and imaging features of the different disorders, and to correlate them with the currently used classification schemes. Twenty-five patients with fibrous tumours were evaluated retrospectively. Clinical histories were studied for the histopathological diagnosis, age, signs and symptoms at presentation, mode of therapy and follow-up where available. Imaging findings were analysed for the following variables: number, location, size, margin and architecture of soft tissue and/or visceral lesions and the presence and pattern of osseous involvement. Comparison with the available literature was performed. The following tumour types were encountered: desmoid fibromatosis (n = 9), myofibromatosis (n = 7), fibromatosis colli (n = 2), congenital-infantile fibrosarcoma (n = 2), adult-type fibrosarcoma (n = 2), fibrous hamartoma of infancy (n = 1), angiofibroma (n = 1) and hyaline fibromatosis (n = 1). While some tumours were non-specific in their clinical and radiological manifestation, others such as myofibromatosis, fibromatosis colli, fibrous hamartoma of infancy and angiofibroma exhibited a characteristic pattern which allowed a diagnosis to be made even without histology.

Fibromatosis colli. The utility of fine-needle aspiration in diagnosis.

Fibromatosis colli (FC), also known as sternocleidomastoid tumor of infancy, is a benign spindle cell lesion of the sternocleidomastoid muscle. It usually is seen in the first few weeks of life and is the most common cause of a neck mass in the perinatal period. Although FC may lead to congenital muscular torticollis requiring surgical intervention, if the diagnosis of FC is certain, the usual initial treatment option is conservative management. To show the utility of fine-needle aspiration in the diagnosis of FC. Five cases in which fine-needle aspiration was used in the evaluation of patients with FC were identified retrospectively by a search of the cytopathology files of the State University of New York Health Science Center at Syracuse and the Virginia Commonwealth University, Medical College of Virginia, Richmond. Fine-needle aspiration yielded an initial diagnosis of FC in 4 of the 5 cases. Smears made from the aspirated material were of low cellularity, but showed a characteristic population of spindle-cell fibroblasts. In addition to these fibroblasts, a variable amount of degenerating skeletal muscle was present in the background. With the collaborative efforts of otolaryngologists and pathologists, fine-needle aspiration can be used to confirm a clinical diagnosis of FC while avoiding the expense and risk of open biopsy.

US, CT, and MR imaging of neck lesions in children.

Neck lesions are common findings in pediatric patients and can be classified as congenital, vascular, inflammatory, or tumoral. They can be evaluated with ultrasonography (US), computed tomography (CT), and magnetic resonance (MR) imaging, either alone or in combination. US should be considered first for studying suspected congenital, vascular, and inflammatory lesions, although CT and MR imaging are best for demonstrating the extent of benign and malignant tumors and the presence or absence of bone erosion, vascular encasement, and airway compromise. MR imaging is also preferred for ruling out intracranial and intraspinal extension (eg, as occurs in rhabdomyosarcoma and neuroblastoma, respectively). In the authors' experience, thyroglossal duct cysts and lymphangioma are the most common congenital anomalies; jugular vein aneurysms are the most common vascular lesion; lymphadenitis is the most common inflammatory lesion; fibromatosis colli is the most common benign tumor or tumorlike condition; and lymphoma is the most common malignant neoplasm.

Fibroblastic-Myofibroblastic Tumors in Children and Adolescents: A Clinicopathologic Study of 108 Examples in 103 Patients

A review of over 900 soft tissue tumors in children and adolescents revealed 108 fibroblastic-myofibroblastic tumors in 103 patients from newborn to 20 years of age, which had been accessioned in a 25-year period. Based on clinicopathologic criteria, 82 (76%) were regarded as benign, 14 (13%) as borderline, and 12 (11%) as malignant. The average age at diagnosis for the entire series was 7 years with a male/female ratio of 1.8:1. The most frequent topographic site was the extremities (48, 44%), followed by the trunk (31, 29%) and the head and neck region (27, 25%). Virtually 50% (51 tumors) of cases were diagnosed during the first year of life, and 73 (71%) occurred in the first decade. The known recurrence rate was 16% (17 cases). Fibromatosis of various subtypes accounted for 95% of the histologically benign group. Infantile myofibromatosis was the most frequent form of fibromatosis, followed by aggressive (desmoid) fibromatosis (20 cases, 19%). Ninety percent of infantile myofibromatoses were diagnosed in the first year of life. In contrast, 70% of aggressive fibromatoses occurred in the second decade. Associated conditions included familial desmoid fibromatosis, Gardner syndrome, and previous surgery. The borderline category was represented by the 14 (13% of the series) congenital-infantile fibrosarcomas. All of the 14 (13%) malignant tumors were classic adult-type fibrosarcomas that occurred only in later childhood and adolescence. Fibromatosis colli, fibrous hamartoma of infancy, juvenile nasopharyngeal angiofibroma, Dupuytren-type fibromatosis, infantile digital fibromatosis, juvenile aponeurotic fibroma, unclassified fibromatoses, and fibroma of tendon or nerve sheath constituted the remaining cases.

Superficial fibrous tumors in childhood.

A review is made of superficial fibrous tumors of childhood and differences between the pattern of fibrous tumor proliferation in children and adults are discussed. The fibrous tumors that occur specifically in childhood and infancy include recurring digital fibrous tumor, juvenile aponeurotic fibroma (cartilage analogue of fibromatosis), juvenile hyalin fibromatosis, fibrous hamartoma of infancy, congenital fibromatosis and fibromatosis colli (Torticollis). Palmoplantar fibromatosis and fibrosarcoma may appear in all ages. Dupuytren contracture, however, is not usually observed early in life. Similarly, the histiocytomas and dermatofibromas which are the most common fibrous tumors of adults are extremely rare in childhood.

The fibromatoses. A histological classification of 156 cases

This study was based on 156 cases of fibromatoses seen at the Soft Tissue Branch of the Armed Forces Institute of Pathology, the Australian Soft Tissue Tumour Registry and the Institute of Medical and Veterinary Science, Adelaide. There were 86 'adult' fibromatoses, 50 'juvenile' fibromatoses, and 20 unclassified lesions. 'Adult' fibromatoses, found predominantly in patients older than 20 yr, fell into 2 main groups; the Dupuytren type fibromatoses (27) and the desmoid tumours (59). In the former group, there were 5 cases of palmar fibromatosis, 15 of plantar fibromatosis, 3 knuckle pads (dorsal fibromatosis), 4 lesions resembling palmar fibromatosis in unusual locations, and no cases of Peyronie's disease. In the desmoid group, there were 13 abdominal desmoids, 39 extra-abdominal desmoids, one mesenteric fibromatosis, 3 examples of multiple extra-abdominal desmoids, one of abdominal desmoid and mesenteric fibromatosis, and 2 of Gardner's syndrome. Six desmoids occurred in scars. There were no cases of multiple familial desmoids. 'Juvenile' fibromatoses occurred predominantly or exclusively in the first 2 decades of life. There were 11 congenital 'fibrosarcomas', 2 congenital generalized fibrornatoses, 8 solitary lesions resembling congenital generalized fibromatoses, 4 fibromatosis colli, 3 diffuse infantile fibromatoses, 5 fibrous hamartomas of infancy, 5 recurring digital tumours of childhood and 12 juvenile aponeurotic fibromas. As a group, the fibromatoses are best regarded as non-metastasizing proliferations of fibrous tissue which may recur locally after excision. They may be both multiple and familial, their growth rate frequently decreases after an initial period of rapid growth, and they may regress spontaneously.
