Phyllodes tumors of the breast are rare, accounting for less than 1% of the breast tumors. They are mostly seen in women between 45 and 49 years old. These are fast growing tumors with a large spectrum of behavior (from benign to metastatic) and can resemble fibroadenomas. Correct diagnosis mostly through core needle biopsy is important to decide whether a surgical excision has to be done. Here we report a case of a 57-year-old woman with a fast growing, ulcerated tumor in the left breast. Core needle biopsy suggested a malignant phyllodes tumor with heterologous liposarcomatous differentiation...

We describe a case of an unusual endometrial endometrioid carcinoma occurring in a 67-year-old woman. The tumor involved uterine corpus as well as lower uterine segment and presented as polypoid tumor protruding through the cervical orifice. Microscopically, the tumor was characterized by broad zones of cytologically bland fibromyxoid stroma resembling nodular fasciitis, showing vaguely nodular architecture. Neoplastic glands were characterized by interconnected elongated slit-like and large cystic profiles, mostly lined by flattened epithelium with variable squamous differentiation, whereas typical columnar endometrioid cells were only focally present...

BACKGROUND: Malignant phyllodes tumors of the breast are rare biphasic neoplasms. Only few cases related to pregnancy have been reported. CASE REPORT: A 37-year-old woman presented with swelling and pain in her left breast as well as hyperemia on the breast skin, 4 weeks after labor. In her family history, her aunt and maternal cousin had had a breast cancer diagnosis. Clinical evaluation of the patient was consistent with a breast abscess. Therefore, abscess drainage and biopsy from the cavity wall were performed...

Attempts at identification of an ideal prognostic/predictive biomarker in phyllodes tumour (PT) have not been fruitful so far. Studies evaluating c-kit expression in PT have shown contradictory results. Recently aldehyde dehydrogenase 1A1 (ALDH1A1) was proposed as a stem cell marker for malignant PT but its expression has not been studied in benign and borderline tumours. We aimed to evaluate expression and prognostic significance of c-kit and ALDH1A1 in different grades of PT. Epithelial and stromal c-kit and ALDH1A1 expression were studied in 104 PT cases (86 primary and 18 recurrent tumours) and compared with different clinico-pathological features and recurrence rates...

BACKGROUND: Malignant phyllodes tumor (PT) is a rare fibro epithelial neoplasm of the breast, which is poor prognosis due to high risk of recurrence and distant metastasis. METHODS: We report a case of malignant PT. It had recurred locally five times, and the sixth relapse was occurred 54 months after first diagnosis, presenting a huge pelvic mass (14 cm × 11 cm) by CT scan. Histopathological examination has demonstrated a metastatic phyllodes tumor. After postoperative chemotherapy treatment, a longer survival has been achieved, which is more than 72 months...

Phyllodes tumors (PTs) are rare fibroepithelial tumors of the breast with epithelial and stromal components, and surgical resection is the standard and only available treatment for malignant PTs. To provide a better understanding of these tumors, we developed mouse models that recapitulate the pathological and clinical properties of human malignant PTs. Mouse undifferentiated mammary gland cells were infected with a retrovirus encoding the human oncoprotein H-Ras(G12V) , and the infected cells were transplanted orthotopically into the mammary fat pads of syngeneic mice...

INTRODUCTION: Primary extra osseous osteogenic sarcomas have been reported in many tissues of the body but their occurrence in the breast is extremely rare. It can arise as a result of osseous metaplasia in a pre-existing benign or malignant neoplasm of the breast. CASE PRESENTATION: A 24 year-old young lady was diagnosed to have mass in right breast.Tru cut biopsy showed it was malignant phyllodes tumour. There was no distant metastasis or any axillary lymph nodes palpable...

Mixed epithelial and stromal tumor of the kidney is an uncommon complex neoplasm, and previous studies have included only a modest number of cases and have left gaps in our understanding of its morphology. We analyzed 53 tumors (46 F, median age: 49 y), collecting data on gross, histologic, and immunohistochemical features. The most common gross appearance was solid and cystic (47%). Hypocellular fibrous and cellular spindle cell stroma were the most common stromal types, followed by smooth muscle differentiation, edematous stroma, and adipose tissue...

INTRODUCTION: Benign Phyllodes Tumours (PTs) are rare fibroepithelial neoplasms that resemble fibroadenoma. But unlike fibroadenoma, benign PT can recur and both stromal & epithelial components can progress to malignancy. Contrary to earlier belief that benign PT is a stromal neoplasm and possibly arises from fibroadenoma, more recent molecular studies have suggested that both stroma and epithelium can become neoplastic. Sometimes, benign PT can occur synchronously with fibroadenoma. Here histomorphologic analysis of eleven cases of benign PT are presented including some unusual features...

We report a patient with a giant phyllodes tumor of the right breast associated with a hypoglycemic attack. A 48-year-old woman experienced a loss of consciousness and was transferred via ambulance to our hospital emergency department. Upon arrival, her blood glucose level was 26 mg/dl, and a giant tumor (>20 cm in diameter) with skin ulceration was observed on the right breast. Core needle biopsy led to a histological diagnosis of a phyllodes tumor of the breast. Ultrasonography and computed tomography detected neither distant metastasis nor a pancreatic endocrine tumor...

The Li-Fraumeni syndrome is characterized clinically by the appearance of tumors in multiple organs generally at an early age. This hereditary condition is caused by germinal mutations in the TP53 gene, which codifies for the tumoural suppressor gene p53. We present the case of a patient aged 31 with clinical and molecular diagnosis of Li-Fraumeni syndrome who presented two synchronous tumors: a leiomyosarcoma on the forearm and a phyllodes breast tumour. She had a family history of cancer, including a son diagnosed with a cortical adrenal carcinoma when he was three years old, who died at five from the disease...

Breast sarcomas are a diverse group of neoplasms arising from the nonepithelial and mesenchymal tissues of the breast. Their behaviors vary from the more indolent tumors like cystosarcoma phyllodes to the extremely aggressive angiosarcoma. They should be approached in a similar fashion to their soft tissue sarcoma counterparts in other locations and managed by multidisciplinary sarcoma specialists with attention to wide-margin surgical excision. The use of adjuvant chemotherapy is controversial and should be discussed on a case-by-case basis and preferably given in the context of a clinical trial...

Metastasis of a phyllodes tumor to the stomach is an extremely rare condition with important clinical implications. A 44-year-old woman was initially diagnosed with a phyllodes tumor in her right breast in 2008, and subsequently presented to an out-patient clinic with dizziness on December 16, 2013. We found that she had severe anemia (hemoglobin levels: 6.7 g/dL), and we quickly performed esophagogastroduodenoscopy to identify the cause. This procedure revealed large ulcerofungating masses with active bleeding in the stomach...

Breast tumors in pregnancy are often times diagnosed at advanced stages secondary to difficulty distinguishing between pathologic from normal physiologic changes. Often benign, phyllodes tumors are rare fibroepithelial stromal tumors of the breast, most commonly diagnosed in the 4th and 5th decades of life. However, these tumors may be characterized by malignancy with metastases in 10% of cases. In this paper, we report a novel case of a young woman presenting at 8 weeks gestation with a large borderline phyllodes tumor...
