ABSTRACT
Phyllodes tumors (PT) are rare neoplasms accounting for <1% of breast lesions. A transformation of a fibroadenoma (FA) to a PT is even more rare and unpredictable. Many challenges face PT management, since diagnostic through surgical treatment. We describe a case of a 63-year old woman with PT that was previously diagnosed as a FA who underwent an oncoplastic conservative surgery. A review of the literature on the diagnostic and surgical management of PT was performed. The diagnostic of PT can be hard mostly in needle biopsy, and the close follow up of negative lesions is recommended. Oncoplastic techniques might be an important tool on the conservative treatment of these patients.
O tumor filoide (TF) é uma rara neoplasia que corresponde a menos de 1% das lesões mamárias. A tranformação do fibroadenoma (FA) em TF é um evento raro e imprevisível. Existem muitos desafios no manejo dos TF, desde o seu diagnóstico ao tratamento. Nós descrevemos o caso de uma paciente de 63 anos com TF com diagnóstico prévio de FA que foi submetida ao tratamento cirúrgico conservador da mama por técnicas oncoplásticas. Uma revisão da literatura sobre o diagnóstico e tratamento do TF foi realizada. O diagnóstico dessa condição pode ser especialmente difícil quando feito a partir de amostra de biópsias por agulha, e em caso de resultados negativos recomenda-se acompanhamento rigoroso. As técnicas oncoplásticas podem ser uma importante ferramenta no tratamento cirúrgico conservador desses pacientes.
ABSTRACT
PURPOSE: Breast conserving surgery(BCS) for breast cancer has a common treatment protocol. Oncoplastic surgery represents a form of BCS which combines both a cosmetic mammoplasty approach and oncologic resection for the treatment of breast cancer. Depending on the tumor site, BCS can make an unsatisfactory cosmetic result, especially in inferiorly placed tumors. This study describes the use of oncoplastic techniques for inferiorly located breast tumors in immediate partial mastectomy reconstruction. METHODS: From September of 2006 to February of 2008, these techniques were used in 11 patients at the OO hospital. After BCS was preceded, breast reshaping by oncoplastic techniques were selected depending on the location and size of the tumor within the breast as well as the size of breast itself. Oncoplastic techniques after partial mastectomy included 'Wise pattern (inverted T)' reduction mammoplasty, 'vertical pattern' mammoplasty, 'J-pattern' mammoplasty. In order to improve the cosmetic outcome, repositioning of the nipple areola complex(NAC) or reshaping of the contralateral breast may be considered additionally. RESULTS: These techniques have been used in 11 patients. The mean age was 51 and the average follow- up period was 8 months. Eleven of these patients underwent the 'Wise pattern(inverted T)' reduction mammoplasty(n=6), 'vertical pattern' mammoplasty(n=3) and 'J-pattern' mammoplasty(n=2). There was one wound dehiscence during the follow-up periods. This complication was treated by conservative approach. The overall cosmetic result was evaluated in 6 months. The majority of patients were satisfied at the cosmetic result. CONCLUSION: Oncoplastic techniques in inferiorly located breast tumors could be a reasonable and safe option for breast cancer patients who desire conserving surgery with esthetical breast.
