Background: Phyllodes tumors of the breast are rare fibroepithelial lesions, so relatively little is known about this disease entity. The present study was designed to identify differences in clinical features between benign borderline and malignant phyllodes tumors. Materials and Methods: Data from 246 women with phyllodes tumors of the breast treated in Cancer Hospital Chinese Academy of Medical Sciences between 2002 and 2012 were collected and analyzed, including age at presentation, age at treatment, course, size of primary tumor, location, histological type, type of surgery and treatment, local recurrence, distant metastasis, fibroadenoma history, disease-free survival and number of mitosis per 10hpf. There are 125 (55%) benign, 55 (24%) borderline and 47 (21%) malignant tumors. Results: In univariate analysis, average age at presentation, average age at treatment, size of primary tumor, ulceration or not, type of primary surgery, distant metastasis and number of mitosis per 10 hpf turned out to be statistically different among the three PT types (p=0.014, 0.018, <0.000, 0.003, <0.000, 0.001 and <0.000, respectively), while recurrence and disease-free survival (DFS) demonstrated trends for statistical significance (P =0.055 and 0.060, respectively). Multivariate analysis revealed distant metastasis and excision were significantly different in benign, borderline and malignant phyllodes tumors of the breast (p=0.041 and 0.018, OR=0.061 and 0.051). At the same time, size of primary tumor with p=0.052 tended to be different between groups (OR=1.127). However, age at treatment, ulceration and DFS showed no statistically significant variation (p=0.400, 0.286 and 0.413, respectively). Conclusions: Benign borderline and malignant phyllode tumors have different distant metastasis risk, different primary tumor size and different surgical procedures, and malignant PTs are more likely to be bigger and to metastasize.

Phyllodes tumors of the breast are relatively rare fibroepithelial tumors that account for less than 1% of primary breast neoplasms. Phyllodes tumors have epithelial and stromal components and they originate from the periductal stroma. They are classified as benign, borderline, or malignant. Carcinomatous differentiation of the epithelial components of phyllodes tumors is rare, and their imaging features have not been accurately described. Herein, we report a rare case of invasive ductal carcinoma originating from a borderline phyllodes tumor in a 21-yearold female with radiologic and pathologic findings.

Objects : This study is a report on treatment effect of the case that treated by using of Korean medical treatment to phyllodes tumors(PT) of breast patient. Methods : The patient diagnosed with PT of breast was treated by using of acupuncture, manipulation therapy and herbal medicine. VAS scale was used as the tool of treatment effect. Results : Although the tumor size was intact, the Korean medical treatment reduced the breast pain(VAS 5 → 1). Conclusions : This study suggests that the oriental medical treatment might be useful for breast pain reduction in PT of breast patient, and make a psychological stability of the patient.

Myxoid liposarcoma is an extremely rare malignant breast tumor. We report the case of a 44-year-old woman who had myxoid liposarcoma of the breast with a history of phyllodes tumor and describe the imaging findings on US, mammography, and MRI. Before surgery, the mass was considered to be a recurrent phyllodes tumor. However, using US, we retrospectively identified some differences between myxoid liposarcomas and phyllodes tumors.

Phyllodes tumor(PT) is a rare distinctive fibroepithelial breast tumor that occasionally shows unpredictable clinical behavior. Wide excision should be the primary treatment of PT and enucleation, the standard procedure for fibroadenoma(FA), is proscribed due to high frequency of local recurrence. Therefore an accurate preoperative diagnosis of PT is essential in order to ensure proper surgical treatment. However, the differentiation between benign PT and FA is often difficult on the basis of cytologic findings. In an attempt to better understand the cytologic features of benign PT and possibly to differentiate PT from FA on the findings of fine needle aspiration(FNA) smears, we reviewed cytologic smears from 22 histologically diagnosed cases each of benign PT and FA, respectively. The cytologic features assessed were cellularity and atypia of both epithelial and stromal components, and shape of epithelial cell clusters. Atypia of stromal cells was more frequent in PT, while blunt branching pattern of epithelial cells was more frequent in FA. The specific cytologic diagnosis of PT is not possible in many cases, but the abundance of stromal cells with moderate nuclear atypia in the correct clinical setting such as older age and larger size(>4cm) allows the diagnosis.

Nodular fasciitis is a benign proliferative lesion of the fibroblasts and/or myofibroblasts, generally detected in the soft tissue of the upper extremities. It has also been reported in the lower extremities, head, and neck, and rarely in the breast. Its rarity and nonspecific clinical and radiological features resemble those of malignant tumors of the breast and make the differential diagnosis and management difficult. Herein, we present a rare case of nodular fasciitis of the breast, which was initially suspected to be a phyllodes tumor.

Periductal stromal sarcoma (PSS) is a type of rare malignant fibroepithelial tumor. PSS is a recently introduced diagnostic entity and there are few reports about radiological features of this tumor. Pre-operative diagnosis is difficult because it reveals similar symptoms with other benign and malignant tumors with absence of specific radiologic findings. We present a woman age 30 that underwent mammotome biopsy for a BI-RADS 4 lesion on her left breast and received histopathology diagnosis of a phyllodes tumor. Additionally, she underwent a wide excision depending on her histopathology diagnosis. Her final diagnosis was PSS. Six months later, no recurrence was detected. However, frequent follow-up is needed because PSS can develop into phyllodes tumor or entity of breast cancer.

Purpose: To estimate the incidence of breast cancer in Yemeni female patients presenting with a breast mass. Materials and Methods: This retrospective study was carried out with 595 female patients with palpable breast lumps, attending to Alkuwait university hospital, Sana'a, Yemen. Triple assessment, including breast examination, mammography and biopsy (FNAC, core needle, or excision), for all patients were performed. Results: The incidences of benign and malignant lesions was calculated. Some 160 (26.9%) of 595 patients had malignancies; 213 (35.8%) were fibroadenomas; 12 (2.0%) were fibrocystic change; 143 (24.03%) were inflammatory lesions (including mastitis and ductectasia); 62 (10.4%) were simple cysts, while 5 (0.8%) were phyllodes tumors. The mean age of patients with malignant lumps was 44.3 years. Conclusions: Among Yemeni female patients with palpable breast lumps, the rate of breast cancer is high, with occurrence at an earlier age than in Western countries. Improving breast cancer awareness programs and increasing breast cancer screening centers inb different areas of Yemen are needed to establish early diagnosis and offer early and optimal treatment.
