Laparoscopic Excision of Anterior Abdominal Wall Tumors: A Case of Desmoid-Type Fibromatosis Arising in the Rectus Muscle

PURPOSE: Laparoscopic approaches to the anterior abdominal wall are difficult because of the inherent limitations of laparoscopic surgery. METHODS: A 25-year-old young female visited to our hospital with an incidentally-found palpable abdominal mass. Computed tomography revealed a 7-cm round enhancing mass arising from the left posterior rectus sheath. The patient underwent laparoscopic excision of the inner mass arising from the anterior abdominal wall. RESULTS: The operation lasted for 45 minutes and there was no measurable bleeding during the procedure. Pathological assessment revealed that the tumor was a DTF 7.0 cm in size. The patient was discharged on the second postoperative day in good condition, and is currently being followed on a routine basis for surveillance without adjuvant therapy. CONCLUSION: Laparoscopic approach for the anterior abdominal wall tumor could be feasible in select patients. This minimally-invasive approach helps to ensure good cosmetic outcomes and quality of life.

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.
