Does a Vertebra Fracture Cause a Tumor? A Dorsolumbar Paraspinal Desmoid Tumor: Case Report

Extraabdominal desmoid tumors are uncommon soft-tissue tumors. The etiology of the tumor is still unclear. Injury is one of the etiological factors of soft-tissue tumors. A 41-year-old female patient who had a traumatic vertebral body fracture on the thoracic spine was treated conservatively. Two and a half years later, she presented a painful, palpable swelling on the thoracolumbar region. In the present report, was discuss the patient, who underwent a surgery to remove the desmoid tumor (aggressive fibromatosis), within the context of the current literature. The literature on desmoid tumor caused by a trauma is rare. This is the first case that demonstrates an extraabdominal desmoid tumor following a spinal fracture. The swelling on the region of the trauma must be examined carefully and desmoid tumor must be kept in mind as a possible diagnosis.

Role of Nonsteroidal Anti-inflammatory Drug in Treatment of Extra-abdominal Desmoid Tumors

BACKGROUND: We retrospectively reviewed the outcomes of patients who had been treated with meloxicam for the extra-abdominal desmoid tumors and evaluated the correlation between clinical outcome and clinic pathological variables. METHODS: Twenty patients treated with meloxicam were followed up every 3 to 6 months. Meloxicam administration was planned at 15 mg/day orally for 6 months. RESULTS: Of the 20 patients evaluated, according to Response Evaluation Criteria in Solid Tumors criteria, there were five patients with partial response (25.0%), eight with stable disease (40.0%), and seven with tumor progression (35.0%). The cumulative probability of dropping out from our nonsurgical strategy using meloxicam was 35.0% at 1 year and 35.0% at 5 years. CONCLUSIONS: The present study suggests that conservative treatment would be a primary treatment option for this perplexing disease even though we were not able to determine that the use of a cyclooxygenase-2 inhibitor would have an additional influence on the natural course of a desmoid tumor.

Extra abdominal mammary fibromatosis (Desmoid tumor) of breast in an elderly female.

The extra-abdominal form of desmoid tumor is very rare and the incidence of mammary desmoid tumor is <0.2% of primary breast neoplasm. We report a case of mammary fibromatosis in an elderly female in which no associated risk factor was discernible. After simple mastectomy as per the patient’s wish, in view of posterior margin positivity, adjuvant radiotherapy was given. The patient has remained recurrence free after one year of follow up.

Pediatric fibromatosis involving mandible: case reportand a five-year post-operative follow-up / Fibromatose pediátrica em mandíbula: relato de caso e avaliação pós-operatória de cinco anos

Extra-abdominal fibromatosis is a benign fibrous neoplasm of locally aggressive behavior. Surgical excision with a wide margin is the treatment of choice. The aim of the present work is to report the case of fibromatosis in an 11-year-old melanodermic patient, who showed swelling in the area of the right mandible. Conservative surgery was performed based on the initial histopathological diagnosis of benign lesion suggestive of neural origin. The new anatomopathological examination of the surgical specimen was compatible with fibromatosis. The patient is still under periodic observation as part of the five-year surgical follow-up, showing no signs of recurrence.

Fibromatose extra-abdominal é uma neoplasia fibrosa benigna, caracterizada por comportamento agressivo local. Geralmente, o tratamento de escolha consiste na excisão cirúrgica com ampla margem de segurança. O objetivo deste trabalho é relatar um caso de fibromatose em uma paciente de 11 anos, melanoderma, que apresenta aumento de volume na mandíbula do lado direito. A partir do diagnóstico histopatológico inicial sugestivo de lesão benigna de origem neural, foi realizado tratamento cirúrgico conservador. Um novo exame anatomopatológico da peça cirúrgica foi compatível com fibromatose. A paciente encontra-se sob controle periódico de cinco anos da cirurgia, não havendo recorrência clínica da lesão.
