This report presents a unique case of a 56-year-old female diagnosed with a malignant phyllodes tumor (PT). Following a modified radical mastectomy, the patient exhibited metastasis to the lungs, bones, and, uncommonly, the scalp. Despite treatment interventions, including chemotherapy and radiotherapy, the patient's condition progressed, underscoring the aggressive nature of malignant PTs. This case emphasizes the importance of recognizing unusual metastatic sites and the challenges in managing such aggressive tumors.

Giant fibroadenomas are common in young females and are rarely reported in perimenopausal or menopausal females. These fibroadenomas are observed as single, mobile, small to large, with distinct boundaries. These tumors are hyperplastic and characterized by their aberrant growth in both the epidermal and mesenchymal layers, which can be accompanied by pain in some instances. These tumors have similar clinical resemblances to other epithelial and stromal tumors, such as phyllodes tumors, except for the level of disease severity and malignancy. Treatment of giant fibroadenomas includes surgical resection. Surgical excision is done by complete excision of the fibroadenoma, with the rest of the breast tissue and the nipple-areolar complex preserved. Timely diagnosis can be helpful in the prevention of adverse outcomes. This is a case of a 40-year-old female who presented with a lump in her right breast, for which she underwent a wide local excision. On histopathology, it was found to be a giant fibroadenoma. Her postoperative recovery was uneventful.

INTRODUCTION
Primary breast sarcoma (PBS), excluding phyllodes tumors, is an extremely rare and heterogeneous group of cancers, accounting for <1 % of all breast cancers. PBS is typically diagnosed in the fifth or sixth decades of life. There are no pathognomonic clinical or radiological features. Diagnosis is generally established through a microbiopsy. For young women, the diagnosis can be confused with a benign pathology.
CLINICAL PRESENTATION
Our patient was 27 years old, with no family or personal history of breast cancer, which was initially brought to the emergency department with a breast abscess. The clinical diagnosis of abscessed mastitis was made. The patient underwent tissue excision with evacuation of blood clots and necrotic tissue. Histopathological examination revealed a primary breast sarcoma. An MRI showed locally advanced retro-glandular tumor. An abdominal and pelvic CT scan performed showed no evidence of secondary locations. Therefore, the patient was referred for neoadjuvant radiotherapy and chemotherapy. After the third course of chemotherapy, the patient died following cardiogenic shock.
DISCUSSION
The PBS in younger women is extremely rare. The etiopathogenesis remains undetermined. The clinical and radiological characteristics of PBS mimic breast adenocarcinoma. Mastectomy is the treatment of choice but in the case of locally advanced tumor, the use of neoadjuvant chemotherapy can be indicated. PBS presents a significantly poorer prognosis.
CONCLUSION
Breast sarcomas are rare malignant tumors for which treatment protocols are not well-established. Further research efforts are needed to improve the understanding and treatment of PBS.

Observational Study
Effect of adjuvant radiotherapy on overall survival and breast cancer-specific survival of patients with malignant phyllodes tumor of the breast in different age groups: a retrospective observational study based on SEER.
PURPOSE
Malignant phyllodes tumor of the breast (MPTB) is a rare type of breast cancer, with an incidence of less than 1%. The value of adjuvant radiotherapy (RT) for MPTB has been controversial. The aim of the study was to explore the effect of radiotherapy on the long-term survival of female patients with MPTB at different ages.
METHODS
Female MPTB patients were selected from the Surveillance, Epidemiology, and End Results (SEER) database between 2000 and 2020. A Kaplan-Meier survival analysis was conducted to investigate the value of RT for the long-term survival of MPTB patients in different age groups. Additionally, univariate and multivariate Cox regression analyses were performed for overall survival (OS) and breast cancer-specific survival (BCSS) of MPTB patients. Furthermore, propensity score matching (PSM) was also performed to balance the differences in baseline characteristics.
RESULTS
2261 MPTB patients were included in this study, including 455 patients (20.12%) with RT and 1806 patients (79.88%) without RT. These patients were divided into four cohorts based on their ages: 18-45, 46-55, 56-65, and 65-80. Before adjustment, there was a statistically significant difference in long-term survival between RT-treated and non-RT-treated patients in the younger age groups (age group of 18-45 years: OS P = 0.019, BCSS P = 0.016; age group of 46-55 years: OS P < 0.001, BCSS P < 0.001). After PSM, no difference was found in long-term survival of patients in both younger and older groups regardless of whether they received RT (age group of 18-45 years: OS P = 0.473, BCSS P = 0.750; age group of 46-55 years: OS P = 0.380, BCSS P = 0.816, age group of 56-65 years: OS P = 0.484, BCSS P = 0.290; age group of 66-80 years: OS P = 0.997, BCSS P = 0.763). In multivariate COX regression analysis, RT did not affect long-term survival in patients with MPTB.
CONCLUSION
There is no evidence that long-term survival of MPTB patients in specific age groups can benefit from RT.

RATIONALE
Breast malignant phyllodes tumors (MPT) are quite uncommon. It is rarely reported that they occur in conjunction with breast cancer. We detailed a case in which an MPT and ductal carcinoma in situ carcinoma occurred simultaneously in 2 different breasts.
PATIENT CONCERNS
A 79-year-old female patient was seen for a rapidly growing lump in the upper left quadrant of her breast. The lump was described as huge, hard, irregular, and palpable. MRI of the breasts revealed a big mass in the left breast and a smaller lump in the right.
DIAGNOSIS
Ductal carcinoma in situ with breast MPT.
INTERVENTIONS
We performed a double mastectomy. Post-operative endocrine treatment was suggested.
OUTCOMES
During the 18-month follow-up period, no signs of recurrence or metastasis were seen. The ultrasound examination of the chest wall showed no abnormality. Bilateral axillary and supraclavicular ultrasonography showed no lymphadenectasis and a CT scan of the lungs showed no suspicious cancer nodules.
LESSONS
It is possible for MPT and ductal carcinoma in situ to occur simultaneously in different breasts. Surgeons need to integrate clinical observations, imaging tools, and patient history to make an early diagnosis. Before undergoing surgery, a thorough examination of both breasts is required.

Ruptured phyllodes tumors, though extremely rare, can necessitate emergency surgery in certain cases, particularly those with active bleeding. A 51-year-old woman presented to our hospital with a newly identified mass in her right breast that developed over the past two months. The tumor had ruptured through the paramammary nipple. While initially diagnosed with a phyllodes tumor and scheduled for elective surgery, she experienced active bleeding from the ruptured tumor, leading to a drop in hemoglobin levels. An emergency right simple mastectomy was performed to control the bleeding. Postoperatively, no complications or recurrences were observed. Phyllodes tumors, which are characterized by rapid growth, may present with active bleeding following rupture and may require emergency surgery.

The molecular pathogenesis of breast fibroepithelial tumors continues to be elucidated. Recently, highly recurrent mutations arising in exon 2 at codon 44 were discovered in fibroadenomas and phyllodes tumors. In addition, a high prevalence of promoter mutations in two hotspots (124 and 126 bp upstream from the translation start site) was discovered in up to 65% of phyllodes tumors. Breast periductal stromal tumors are a potentially distinct category of fibroepithelial lesions that are exceptionally rare with controversial classification and pathogenesis. Herein, we report the first comprehensive molecular genetic workup of a breast periductal stromal tumor that harbored a promoter -124C > T mutation, supporting a relation to phyllodes tumors.

We present the case of a 52-year-old female with a giant phyllodes tumor (GPT), which was fungating through the skin that showed fleshy polypoid outgrowths. Histological analysis revealed stromal atypia, mitotic activity, and stromal overgrowth; however, the tumor border was well-defined, and malignant heterologous elements were not observed. Therefore, as some but not all malignant histological characteristics were present, we diagnosed the patient with borderline GPT. In cases of phyllodes tumor (PT) with the unique gross findings of fungation through the skin as fleshy polypoid outgrowths, caution is required for the subsequent course because even if the PT is graded as benign histologically, a malignant process can occur. Pathologists should note that the sampling of the collection site and the ambiguity of the histological grading of PT may affect the final diagnosis of GPT. It is also important to perform surgery with adequate preservation of the resected margins to control recurrence for patients with GPT.

INTRODUCTION AND IMPORTANCE
The presence of eosinophilic inclusion bodies in the breast is very rare and fewer than 20 cases were described in the literature. Herein we report the first case of borderline phyllodes tumour associated with this kind of cells. To the best of our knowledge, this is also the first time that a molecular sequencing is made targeting the stroma cells with inclusion bodies.
CASE PRESENTATION
A 33-yr-old woman presented a large mass in the right breast. Imaging techniques by mammogram and ultrasonographic examination were performed. After multidisciplinary approach, a breast conserving surgery has been decided. Microscopic analysis, immunohistochemical stains and molecular tests were performed on the lesion. The proposed diagnosis is borderline phyllodes tumour with eosinophilic inclusion bodies.
CLINICAL DISCUSSION
Inclusion bodies are typically found in the infantile digital fibromatosis. Finding them in extradigital fibromatosis is rare. Their signification is still unclear. Some studies suggest a disturbance in the metabolism of proliferating myofibroblasts.
CONCLUSION
The presence of inclusion bodies in breast tumour do not seem to have a prognosis impact. It might be interesting to perform others molecular tests on lesions with eosinophilic inclusion bodies to discover potential mutations.

INTRODUCTION
Fine-needle aspiration cytology (FNAC) is often used as a screening tool. Cytopathologist should be aware of various mimickers of the malignancy. One of these is infarction of benign breast lesions. Careful examination of cytomorphological features will avoid the misdiagnosis of malignancy in such cases.
MATERIAL AND METHODS
Six cases were diagnosed as benign breast lesion for 4 years and 5 months in our newly established tertiary referral center. Histopathology follow-up was available in one case.
RESULTS
Of six cases, three cases (50%) were reported as fibroadenoma with infarction, two cases (33%) as benign breast lesion with infarction favor fibroadenoma, and one as breast lesion with infarction favor phyllodes tumor in view of recurrence. Most were in the second or third decade of their life. All cases showed dyscohesive cells with pyknotic nuclei. Monolayered sheets of necrotic cells were seen in the four cases (66%). Viable cells were seen in four cases.
CONCLUSIONS
FNAC provides a rapid and accurate diagnosis of benign breast lesions with infarction in the hands of experienced pathologists who can help in better patient care. Small-sized uniform pyknotic nuclei of dyscohesive cells and regular nuclear membranes help to differentiate them from inflammatory and malignant lesions.
