Identify the etiology of phyllodes breast tumors. In our case, the tumor had no obvious phyllode fissure; however, it partially retained the structure of breast lobules. As far as we know, only sporadic cases were reported ( 1 9 ). This activity describes the evaluation and treatment of phyllodes tumors and highlights the interprofessional team's role in managing patients with this condition. As a biphasic tumor, PDST shows both benign ductal epithelium and non-phyllodes sarcomatous stroma. Upon clinical examination, we found, in the upper outer quadrant of the right breast, a small mass measuring approximately 2cm in size, round in shape, with no signs of inflammation and not associated with axillary lymph nodes. They were mainly distinguished by pathological characteristics. Feel free to get in touch with us and send a message. Periductal stromal sarcoma is an extremely rare malignant fibroepithelial tumor of the breast which is characterized by its biphasic histology with benign ductal elements and a sarcomatous stroma made of spindle cells and lacking phyllodes architecture. Researchers have postulated that stromal induction of phyllodes tumors can occur due to growth factors produced by the breast epithelium. It is characterized by proliferation of atypical spindle cells surrounding benign mammary Breast Imaging-Reporting and Data System (BI-RADS) 3.

However, because of the rarity of the disease, its radiological features were seldom reported. The prognosis of patients with PSS is unclear; thus, more cases of this unusual morphologic variant and longer follow-up of existing and future patients are needed to determine the optimal management and the clinical behavior of this neoplasm. As for the determination of malignancy, this case demonstrated invasive growth, significant pleomorphism, active mitosis (>10/10 HPF or >5/mm2) with pathological mitosis, and was rich in mesenchymal cells, so it was classified as malignant (Figure6).

[20], On ultrasound, phyllodes tumor present as a hypoechoic, partially indistinct, or partially circumscribed mass with frequent posterior enhancement. The spindle-cell stromal nuclei are uniform, and mitoses are rare, generally less than 5 per 10 high-power fields. [7], Unlike breast carcinoma, phyllodes tumors start outside of the lobules, and ducts, in the breasts connective tissue, called the stroma, including the ligaments and fatty tissue surrounding the lobules, ducts, lymph, and blood vessels in the breast.

The key imaging characteristics were the following: (1) multiple solid lobulated lesions comprising nearly the entire right breast; (2) hypoechoic and heterogeneous echo patterns with internal separations and abundant blood flow were noted; (3) FFDM and DBT showed multiple irregular high-density masses with lobulated margin, partially integrated. WebThe tumor microenvironment regulates tissue development and homeostasis, and its dysregulation contributes to neoplastic progression. When the size of a fibroadenoma is greater than 5cm with increased stromal cellularity and epithelial hyperplasia on tissue analysis, it is classified as juvenile fibroadenoma (11). 11:577227. doi: 10.3389/fonc.2021.577227. 2017YFC1309100) and the National Public Welfare Basic Scientific Research Program of Chinese Academy of Medical Sciences (2018PT32003 and 2017PT320004). WebCriteria for periductal stromal hyperplasia included 1) nodular, bland stroma growing as cuffs around normal or altered ducts, 2) no to minimal atypia, and 3) at most 02 stromal mitotic figures per 10 high power fields. In this case, infiltrative growth, rich in interstitial cells, obvious atypia, active mitosis (>10/10 HPF or 5/mm2), and pathological mitosis indicated malignancy. The histological features of PSS were defined by the Armed Forces Institute of Pathology (AFIP) [2] as follows: (1) a predominantly spindle-cell stromal proliferation of variable cellularity and atypia around open tubules and ducts devoid of a phyllodes pattern; (2) one or, more often, multiple nodules separated by adipose tissue; (3) stromal mitotic activity of 3/10 high-power fields; and (4) infiltration into surrounding mammary fibroadipose tissue. Ulceration and nipple retraction are uncommon. Employ interprofessional team strategies for improving care coordination and communication to advance the management of phyllodes breast tumors and improve outcomes. PMC Breast periductal stromal tumor (PDST) is a rare biphasic tumor, with both benign ductal epithelium and non-phyllodes sarcomatous stroma. Frequently phyllodes tumor will show increased vascularity on color or power Doppler. [5], Phyllodes tumor occurs mainly in women, although there are reports of some cases in men. It is characterized by proliferation of atypical spindle cells surrounding benign mammary ducts and infiltrating adjacent adipose tissue. Local recurrences generally develop within 2 to 3 years.[28]. The original contributions presented in the study are included in the article/supplementary material. Surgery with safe margins is the cornerstone of treatment. Genetic risk factors of phyllodes tumors are largely unknown, but the literature describes phyllodes tumors in Li-Fraumeni syndrome patients and a mother and daughter pair. Radiology. Immunohistochemistry was used International journal of radiation oncology, biology, physics. Am J Surg Pathol. PDST is distinguished from phyllodes tumor by its lack of leaf-like architecture; however, it is still unclear whether PDST is a separate entity or a certain spectrum of phyllodes tumor. The resection margins were negative (range, 2mm to 13mm). No use, distribution or reproduction is permitted which does not comply with these terms. The characteristics present on MRI are typically heterogeneously low signal on T1-weighted images, although areas of T1-hyperintense hemorrhage may be visible. Considering the infiltrative characteristic of the tumor, surgical excision with enough margin is required (6). These tumors are diagnosed when the mass does not possess all the adverse histological characteristics found in malignant phyllodes tumors. As a biphasic tumor, PDST shows both benign ductal epithelium and non-phyllodes sarcomatous stroma. Periductal stromal tumor (PDST) is a rare biphasic tumor of the breast that exhibits low-grade malignancy and intermediate behavior. Wabik A, Van Bockstal MR, Berlire M, Galant C. Int J Surg Pathol. It is most likely to originate from the periductal stroma ( 10 ). Most phyllodes tumors behave benignly, with local recurrences occurring in a small proportion of cases. Breast Imaging-Reporting and Data System (BI-RADS) 4A. Periductal stromal tumor (PST) of the breast is a rare fibroepithelial neoplasm with controversial pathogenesis. The residual breast ducts and lobules in the tumor maintained a normal contour, while the cell density at the epithelialmesenchymal junction did not increase significantly. The ducts in the tumor kept a nearly normal contour, and the stromal cellularity adjacent to the epithelium did not obviously increase. The Journal of pathology.

Diagnostic problems due to the lack of phyllodes tumors cause diagnostic problems, because PSS is a distinct, low-grade breast sarcoma with no clinical or radiological specificity. The red box indicated the corresponding area shown in panel (B) Internal bar = 6mm. 1968, 22: 22-28. The authors declare that they have no competing interests. No adjuvant treatment was given. DBT was recommended than FFDM alone as the added value in recognizing suspicious features. The breast journal. Malignant phyllode tumors show a combination of marked nuclear pleomorphism of stromal cells, stromal overgrowth defined as the absence of epithelial elements in one low-power microscopic field containing only stroma, increased mitoses (greater than or equal to 10 per 10 HPF), increased stromal cellularity, which is usually diffuse, and infiltrative borders. The size may range from 1 to 45 cm and may occupy the entire breast. Margin status appears to be the most relevant factor for prognosis.

WebAbstract Periductal stromal hyperplasia is an exceedingly rare biphasic breast tumor with benign ductal elements and spindle-cell stromal proliferation lacking a phyllodes architecture. The primary care provider and nurse practitioner must refer patients with suspected breast masses to an oncologist for further workup. Pre-operative diagnosis is difficult because it reveals similar symptoms with other benign and malignant tumors with absence of specific Our patient is currently recurrence-free 50 months after treatment. FFDM (Senographe Essential, General Electric Company, USA) revealed integrated multiple irregular lobulated high-density masses comprising nearly the entire right breast that is asymmetrically enlarged compared to the left. [16][17], PAX3 and SIX1 expression by immunohistochemistry and gene expression analysis have recently been identified in borderline and malignant phyllodes tumors and correlate with a poor clinical outcome.[18]. Very rarely, the tumor may metastasize, most commonly in the cases of malignant grade tumors. Unlike phyllodes tumors, PDST does not present a leaflike architecture. Malignant phyllodes tumors carry a poor prognosis. Clinically, phyllodes tumors tend to present as unilateral firm, enlarging painless breast masses that stretch the overlying skin with striking distension of superficial veins.

Trauma, pregnancy, increased estrogen activity, and lactation are occasionally implicated as factors stimulating tumor growth. Periductal stromal sarcoma is an extremely rare malignant fibroepithelial tumor of the breast which is characterized by its biphasic histology with benign ductal elements and a sarcomatous stroma made of spindle cells and lacking phyllodes architecture. The surgical pathology confirmed a PDST. These tumors are usually benign, but they can come back and cause the breast to look abnormal if not totally removed.
