Cervical congenital infantile fibrosarcoma: a case report

Background

Congenital infantile fibrosarcoma is a rare mesenchymal tumor seen in children as well as adults. The congenital variety is rare and out of the reported cases only one case sited in the neck has been reported so far. Another such case is presented here who was successfully managed.

Case presentation

A 3-month-old Hindu baby boy presented with a congenital neck swelling. The apparent clinical diagnosis was lympho-venous malformation. With a remote possibility of malignancy, an excisional biopsy was done. Histopathology revealed congenital infantile fibrosarcoma.

Conclusion

A successful excision of cervical congenital infantile fibrosarcoma has not been reported. This diagnosis should be kept as a possibility in all congenital cervical swellings. These are commonly misdiagnosed as lympho-venous malformations and histopathology is confirmatory.

Infantile Fibrosarcoma: Retrospective Analysis of Eleven Patients

Aims and background

Infantile fibrosarcomas are soft tissue sarcomas that are diagnosed at or soon after birth. In the present study, we retrospectively evaluated clinical characteristics, treatment modalities and outcome of patients diagnosed with infantile fibrosarcoma at our institution.

Methods

A retrospective review was conducted to evaluate demographic characteristics, presenting features, type and timing of surgery, other treatment modalities and survival characteristics.

Results

Nine males and 2 females were diagnosed with infantile fibrosarcoma between 1970–2008. The initial surgical procedure was subtotal resection in 4 patients, gross-total resection in 3 and biopsy in 4. Neoadjuvant chemotherapy was given to 10 patients. Three patients died, one for the disease and 2 from complications of therapy. Eight patients are under follow-up with no evidence of disease for 1.3 to 13.5 years. None of the patients in the series underwent amputation.

Conclusions

Owing to the chemosensitive nature of the tumor and possibility of spontaneous regression, neoadjuvant chemotherapy should be considered to prevent extensive or mutilating surgery.

Congenital intestinal fibrosarcoma with rapid recurrence requiring adjuvant chemotherapy

A total of 16 cases of congenital fibrosarcoma have been reported from 1975 to March 2015. Five of the 16 had abnormal fusion between erythroblast transformation specific translocation variant 6 and neurotrophin recptor gene neurotrophic tyrosine kinase, receptor, type 3 (ETV6-NTRK3); in another five out of 16 this was absent, and six were not tested. All were managed by surgical resection but none involved metastasis. Herein we report the case of a newborn baby girl with congenital fibrosarcoma negative for ETV6-NTRK3 gene fusion, who presented with ileal perforation and positive resection margin. She had rapid recurrence with lymph node metastasis treated with postoperative chemotherapy. There was no further recurrence at >3 years of follow up.

Partial fasciectomy is a useful treatment option for symptomatic plantar fibromatosis

Plantar fibromatosis is a rare, benign fibroproliferative disorder of the plantar fascia. It is considered as a low-grade tumour and it can be locally aggressive. It can present as painful swelling with impairment of local function. Upon failure of non-operative management, surgical treatment options include total fasciectomy or partial fasciectomy. Although surgical excision is the mainstay of treatment, recurrence rate can be up to 60%. The aim of this study was to determine the recurrence and complication rates of surgically treated plantar fibromatosis. A retrospective study was conducted involving patients who had a confirmed diagnosis and excision of plantar fibromatosis treated in our institution between 2011 and 2016. Demographic data, follow-up duration, recurrence and complications were reviewed. Eighteen patients underwent 19 operations. Mean age was 41.3 years (20-57). There were 12 male patients. The main presenting features were pain, swelling and impairment of function. They were investigated by ultrasound scan (12 feet, 63%) and/or magnetic resonance imaging (8 feet, 42%). Two patients (11%) had prior surgery at other institutions whilst 3 patients (17%) had multiple nodules at presentation. All patients underwent partial fasciectomy of the plantar fibromatosis. At up to 5 years follow-up, one patient (6%) had a recurrence in our series whilst 3 patients (17%) had scar related problems (2 patients with scar pain and one patient had hypersensitive scar that resolved after 12 months). Symptomatic plantar fibromatosis can be effectively treated with partial plantar fasciectomy.

Primary Pulmonary Fibrosarcoma With Bone Metastasis: a Successful Treatment With Post-Operation Adjuvant Chemotherapy

Introduction:

Pulmonary fibrosarcoma has been an extremely rare tumor in children. Wide surgical resection of infantile fibrosarcoma would be the treatment of choice.

Case Presentation:

Post-operative chemotherapy has shown the benefit in the cases of residual disease after initial surgery and metastatic disease in the literature. We have presented the case of a 70-days old male child with primary infantile fibrosarcoma of the left lung and distant metastasis of skull.

Conclusions:

The aim of this publication was to highlight the role of adjuvant chemotherapy to improve outcome of infantile fibrosarcoma with residual tumor and / or metastatic disease.

Congenital infantile fibrosarcoma: review of imaging features

BACKGROUND

Fibrosarcoma is a rare tumor in children with limited information on imaging features of these tumors in the literature.

OBJECTIVE

To retrospectively review the imaging features of histologically proven congenital infantile fibrosarcoma.

MATERIALS AND METHODS

The list of histologically confirmed congenital infantile fibrosarcomas between November 1999 and June 2013 was obtained from the oncology-pathology database. Imaging features and pathology reports of these tumors were reviewed. Patient charts were reviewed and clinical features, management and outcomes were recorded.

RESULTS

During the study period, 13 children (9 girls and 4 boys; age range: 0 day-16 months, median age: 2.5 months) with congenital infantile fibrosarcomas were available for complete radiological review. The translocation (t[12;15]) was present in 11/13 (84.6%) and absent in 2/13. Eight/thirteen (61.5%) tumors were located in extremities (5 in lower and 3 in upper), 3/13 in thoracolumbar paraspinal regions, and one each in abdomen and sternocleidomastoid muscle. Imaging features included iso- to hyperintensity on T1-W, hyperintensity on T2-W as compared to skeletal muscles and heterogeneous enhancement. Six (37.5%) tumors showed hemorrhagic components and 2 (15.4%) showed low intensity foci. None of the patients had evidence of regional or distant metastases at diagnosis. Management included surgical resection only (1/13) and combined surgery and chemotherapy (10/13). Overall survival was 100% with a median follow-up of 49.3 months.

CONCLUSION

Congenital infantile fibrosarcoma has nonspecific imaging characteristics but should be high on the differential diagnosis in a soft-tissue tumor presenting in infancy, located in an extremity and showing tumoral hemorrhage. Patients have a favorable outcome.

Congenital infantile fibrosarcoma: Association with bleeding diathesis

PATIENT

Male, 2 month

FINAL DIAGNOSIS

Congenital infantile fibrosarcoma Symptoms: Bleeding Medication: Vincristine • actinomycin • cyclophosphamide Clinical Procedure: Surgical resection Specialty: Pediatric Oncology.

OBJECTIVE

Diagnostic/therapeutic accidents.

BACKGROUND

Congenital infantile fibrosarcoma (CIF) is a soft-tissue tumor occurring during the first 2 years of life, most commonly in the extremities. CIF is frequently initially misdiagnosed as a vascular tumor, but its association with bleeding and coagulopathy has not been well characterized.

CASE REPORTS

We describe 2 infants with CIF presenting with bleeding and coagulopathy, requiring urgent intervention. Both patients did well; one underwent partial resection followed by chemotherapy, and the other received 2 cycles of chemotherapy followed by gross total resection. We also provide a review of all reported cases of coagulopathy in the setting of CIF in the English literature, uncovering an association that seems to be more prevalent in patients diagnosed in the neonatal period, with associated anemia and thrombocytopenia, and a significant mortality rate.

CONCLUSIONS

CIF needs to be considered in the differential diagnosis of vascular congenital tumors, especially when there is evidence of bleeding, anemia, or thrombocytopenia.

Margin status and multimodal therapy in infantile fibrosarcoma

PURPOSE

The rarity of infantile fibrosarcoma (IF) has precluded comprehensive treatment evaluation. The purpose of this study was to better define the extent of surgical resection required and the role of chemotherapy.

METHODS

Patients (0-2 years) with IF were evaluated from the National Cancer Data Base (1985-2007). Survival was estimated using the Kaplan-Meier method stratifying patients by margin status and treatment with or without chemotherapy.

RESULTS

Of the 224 patients, 171 (76.3 %) were <1 year of age. Of the 64 (28.6 %) with positive margins, 36 (56.3 %) had microscopic disease, 12 (18.8 %) had macroscopic disease, and 16 (25 %) had unknown margin status; none were found to have metastases. Most were managed with surgical resection (171, 76.4 %). The proportion treated with both surgery and chemotherapy increased over time (18-40 %, p = 0.025). Disease-free survival was 90.6 %. No significant survival difference was noted in this retrospective, non-randomized cohort based on margin status, nodal involvement, tumor size, or treatment modality.

CONCLUSIONS

The use of multimodal therapy has increased over time. There was a small increase in survival associated with negative margins and the use of multimodal therapy, however, neither result reached significance. Future studies investigating tumor biology and chemosensitivity will likely determine the optimal management of IF.

Primary giant congenital infantile fibrosarcoma of the left forearm

Infantile fibrosarcoma is a rare soft tissue tumor in the infant, and only a few cases have been reported as congenital. We report a case of congenital infantile fibrosarcoma of the left forearm at birth. An amputation was performed because the tumor was relapsed soon after surgical removal, and associated with anabrosis and bleeding.

Clinical management of infantile fibrosarcoma: a retrospective single-institution review

BACKGROUND

Infantile fibrosarcoma (IFS) is an uncommon soft-tissue sarcoma. Here we review our experience treating this tumor.

PATIENTS AND METHODS

We retrospectively reviewed records of patients with IFS treated at St. Jude Children's Research Hospital between 1980 and 2009.

RESULTS

We identified 15 patients, 8 girls and 7 boys; 13 white and 2 black. Median age at diagnosis was 3 months. Primary sites included the leg (n = 3), chest wall (n = 2), foot (n = 2), and one each in the tongue, occipital region, axilla, parascapular region, arm, forearm, retroperitoneum, and thigh. All patients underwent resection; 11 upfront surgery, and 4 delayed. Complications included loss of the posterior tibial nerve and artery, axillary vein, biceps, pectoralis major, gallbladder, and transverse/sigmoid sinus. Eight received chemotherapy and three radiotherapy. Seven experienced local recurrence and three lung metastasis. Median follow-up was 65 months. At the time of the review, 12 patients were alive and 3 had died. All deaths were in patients older than 1 year at diagnosis with an axial primary site.

CONCLUSIONS

Non-mutilating surgery should be the primary treatment for IFS. Neoadjuvant chemotherapy is indicated when upfront resection is unfeasible. Patients with positive surgical margins should receive adjuvant chemotherapy. Radiotherapy is indicated for axial primary sites where complete resection is impossible.

Cardiac metastasis and hypertrophic osteoarthropathy in recurrent infantile fibrosarcoma

Cardiac metastasis and hypertrophic osteoarthropathy are both quite rare. We describe a patient presenting with hypertrophic osteoarthropathy as the first symptom of recurrent infantile fibrosarcoma (IF). During surgical resection of lung metastasis, the patient suffered sudden cardiac arrest. Autopsy demonstrated a metastatic lesion in the intraventricular septum of the heart, which is previously undescribed in the literature. This case demonstrates that IF can be aggressive despite its more typical benign course.

Congenital fibrosarcoma of the chest wall: report of a case

Congenital fibrosarcoma (CFS) is a rare soft tissue tumour that usually occurs before the age of 1, and involves the distal extremities. The literature regarding the precise diagnosis and treatment of these tumours is limited. We present and discuss a case of CFS which ended fatally due to lung metastasis after 2 years.
