Phyllodes tumors tend to grow quickly, but they rarely spread outside the breast. In epidermal hyperplasia definition, the World Health Organization classified the phyllodes tumors into three subtypes benign, borderline and malignantaccording to various clinicopathological characteristics, including the degree of stromal cell atypia and stromal overgrowth, tumor necrosis, the status of mitosis and the tumor margin.

Tumoră phyllodes gigantică

In this paper we present a case of giant phyllodes tumor of the breast in a young woman, with its clinicopathological particularities and the different treatment options. Acestea au tendinţa de a creş­te ra­pid, diseminând foarte rar în afara sânului. ÎnOr­ga­ni­za­­ţia Mondială epidermal hyperplasia definition Sănătăţii a clasificat tumorile phyllodes în trei sub­ti­puri benigne, borderline şi maligneîn funcţie de di­fe­ri­tele ca­rac­teristici clinicopatologice, incluzând gradul de ati­pie celulară stromală, gradul de epidermal hyperplasia definition tumorală, numărul mi­to­zelor şi prezenţa invaziei marginilor de rezecţie.

În această lu­cra­re prezentăm cazul unei paciente tinere cu tumoră phyllodes, cu particularităţile clinicopatologice pe care le prezintă şi op­ţiunile diferite de tratament.

The name of the phyllodes tumor comes from the Greek word phullon meaning leaf. Phyllodes tumors are divided into three subtypes benigne, borderline and malignant ,   depending on the degree of the stromal cellular atypia, mitotic activity per 10 high-power fields, degree of stromal overgrowth these three are the maintumor necrosis, and margin appearance.

Borderline tumors have the greatest tendency for local recurrence 2,3. All forms of phyllodes tumors have malignant potential and can behave like sarcomas, epidermal hyperplasia definition metastases to various organs, commonly the lungs, bone and abdominal viscera 4.

The only helmintox kaina eurovaistine option for these tumors is the surgical removal. Case report A year-old female presented to our department in Decemberwith a lump in the left breast that had been gradually increasing for three months.

In the last month before presenting to the hospital, the tumoral mass had ulcerated and started to bleed. A biopsy showed a phyllodes tumor. The patient perfomed total mastectomy without axillary dissection.

Large left breast mass on the clinical examination Macroscopic findings A breast tissue measuring 20×18×13 cm in dimensions was resected Figure 2 epidermal hyperplasia definition Figure 3. Deep margin displays sole smooth surfaced nodules, cut surface is multinodular and shows variable sized fleshy, soft to firm, off-white to ash colored leafy nodules. Figures 2 and 3. The extended area of the epidermis of the covering epidermis, plated with granular tissue with infiltrated polymorphic infiltration lymphocytes, numerous plasmocytes, rare polymorphonuclear neutrophils and eosinophils.

The patient was evaluated gynecologically because of uterine changes that showed the presence of multiple uterine fibroids, and at the level of bone system, by bone scintigraphy, that did not show the presence of bone metastases. Postoperatively, the initiation of adjuvant chemotherapy followed by chest irradiation was discussed.

Inthe World Health Organization classified phyllodes tumors into three subtypes — benign, borderline and malignant —, according to various clinicopathological characteristics, including the degree of stromal cell atypia and stromal overgrowth, tumor necrosis, the status of mitosis and the tumor margin However, the histologic classification epidermal hyperplasia definition not always predict epidermal hyperplasia definition outcome.

The therapeutic decision is difficult to take due to the lack of predictive factors. Different studies have shown that infiltration of resection margins, elevated mitosis rates, and rapid stromal growth are important prognostic and predictive factors Not all patients with positive margins develop recurrence.

KI67 is an important prognostic marker. Another tumor prognostic factor was considered the tumoral size, which was found to positively correlate with distant metastasis, and it was also observed that women with distant metastases tended to present with larger tumors Several authors found radiotherapy to reduce the local recurrence rates, but unlike with the usual invasive breast cancers, radiation did not improve the survival in malignant phyllodes Local recurrences still deve­loped in patients who received radiation, but few studies demonstrated that these women had large tumors and involved surgical margins, which rendered them at high risk of recurrence regardless.

Tan and colleagues developed a nomogram to predict recurrence-free survival, based on stromal atypia, mitoses, stromal overgrowth and surgical margins Even though the nomogram was not developed specifically epidermal hyperplasia definition distant metastasis, it is likely still relevant, since recurrences are more often systemic, rather than isolated local recurrences, in malignant phyllodes.

Conclusions Phyllodes tumors are a heterogeneous tumor group whose prognosis is difficult to define.

Epidermal hyperplasia definition

The epidermal hyperplasia definition cancerul se epidermal hyperplasia definition singur on the histological and biological characteristics of the tumors. The only therapeutic method is the surgical treatment at present, and the complete resection with clear surgical margins appears to be the best predictor of a good survival.

In case of phyllodes benign and borderline tumors, post-resection follow-up remains the method of choice, although adjuvant chemotherapy and radiotherapy are discussed in borderline tumors.

Involved margins are associated with distant metastases, and the conventional chemotherapy and radiation treatments do not appear effective.
