Onco Targets Ther 2021; 14:3003-3011. [PMID: 33986601 PMCID: PMC8110257 DOI: 10.2147/ott.s298379] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/21/2020] [Accepted: 02/25/2021] [Indexed: 11/26/2022] Open
Abstract
Phyllodes tumors (PTs) account for less than 1% of breast tumors, and malignant PTs account for even less. Here, we described an unusual case of malignant PT with mixed liposarcoma (myxoid liposarcoma [MLP] and pleomorphic liposarcoma [PLP]). A 52-year-old woman discovered a small lump in her left breast. Twenty years later, the lump suddenly grew within 1 month. Mammography showed space-occupying lesions of the left breast. Histologically, the tumor was characterized by hypercellular stroma covering the epithelium and protrusion of the myoepithelium into the cyst to form a lobulated structure; regions of loose mucus and hypercellular structures alternated. A region of peripheral benign fibroadenoma was also observed, and many stellate and spindle cells or signet ring-like cells were identified in loose areas. Some areas showed a characteristic thin branching vascular pattern. In the cell-rich area, adipocytes and odd megakaryocytes were observed. Atypical mitotic figures were observed in the cell-rich and mucus areas (16 mitoses/10 high-power fields [HPF] and 2 mitoses/10 HPF, respectively). In the immunohistochemical analysis, a small number of tumor cells were positive for AE1/3 and vimentin, whereas all cells were negative for cytokeratin 34βE12, E-cadherin, p63, estrogen receptor, progesterone receptor, human epidermal growth factor receptor 2, and S-100, ruling out the possibility of metaplastic carcinoma. Interestingly, cyclin-dependent kinase 4, mouse double minute 2 (MDM2), and p16 were strongly positive in both loose mucus and cell-rich areas. However, the fluorescence in situ hybridization test results showed that MDM2 was not amplified. Combined with morphological characteristics, these findings supported that the tumor was a mixed malignant PT with MLP and PLP. Our patient did not receive radiation therapy, and after 47 months of follow-up, no recurrence or metastasis occurred. This case report serves to expand the morphologic spectrum of mixed malignant PT with liposarcoma.

Abstract
INTRODUCTION Phyllodes tumours are rare fibroepithelial malignancies of the breast, accounting for less than 1% of malignant breast tumours. Further malignant differentiation of phyllodes tumours can occur, resulting in cases of extremely rare heterologous sarcomatous differentiation. PRESENTATION OF CASE Two females in their fifties were diagnosed with malignant phyllodes tumour associated with heterologous sarcomatous differentiation. The first patient, aged 50 had phyllodes tumour with chondrosarcoma, osteosarcoma and ductal carcinoma-in-situ. The second patient, aged 53 had phyllodes tumour with osteosarcoma and liposarcoma. DISCUSSION The association of phyllodes tumour and heterologous sarcomatous differentiation is rare, with only 4 previously reported cases in English literature. The paucity of evidence presents challenges in its management with uncertain prognosis and monitoring requirements for two aforementioned patients. CONCLUSION Further case series and long-term follow up is required for accurate characterisation of phyllodes tumours with heterologous sarcomatous differentiation.

Abstract
Background Fibroadenomas are benign human breast tumors, characterized by proliferation of epithelial and stromal components of the terminal ductal unit. They may grow, regress or remain unchanged, as the hormonal environment of the patient changes. Expression of antigen TF in mucin or mucin-type glycoproteins and of galectin-3 seems to contribute to proliferation and transformations events; their expression has been reported in ductal breast cancer and in aggressive tumors. Findings Lectin histochemistry, immunohistochemistry, and immunofluorescence were used to examine the expression and distribution of antigen TF and galectin-3. We used lectins from Arachis hypogaea, Artocarpus integrifolia, and Amaranthus lecuocarpus to evaluate TF expression and a monoclonal antibody to evaluate galectin-3 expression. We used paraffin-embedded blocks from 10 breast tissues diagnosed with fibroadenoma and as control 10 healthy tissue samples. Histochemical and immunofluorescence analysis showed positive expression of galectin-3 in fibroadenoma tissue, mainly in stroma, weak interaction in ducts was observed; whereas, in healthy tissue samples the staining was also weak in ducts. Lectins from A. leucocarpus and A. integrifolia specificaly recognized ducts in healthy breast samples, whereas the lectin from A. hypogaea recognized ducts and stroma. In fibroadenoma tissue, the lectins from A. integrifolia, A. Hypogaea, and A. leucocarpus recognized mainly ducts. Conclusions Our results suggest that expression of antigen TF and galectin-3 seems to participate in fibroadenoma development.

Abstract
Fibroadenomas are human benign breast tumors characterized by proliferation of epithelial and stroma cells of the terminal ductal unit. Expression of O-glycans seems to contribute to the proliferation and transformation events. With this in mind, we evaluated the expression of glycans in fibroadenoma tissue through immunohistochemistry with antibodies against mucin epitopes (Anti CA15-3 and MUC1), as well as with lectins specific for glycans linked to proteins or lipids, and we compared findings with healthy breast specimens. Our results show positive expression of CA15-3 and MUC1 in fibroadenoma tissue, mainly in duct and stroma cells, whereas, in normal samples, staining was observed in duct cells. The lectin from Glycine max recognized equally well duct and stroma cells; this was the only lectin showing co-localization with anti-CA15-3 in healthy and tumor tissues. Dolichos biflorus, Artocarpus integrifolia, and Griffonia simplicifolia lectins recognized duct cells in control healthy tissues as well as in fibroadenoma tissue. The lectin from Amaranthus leucocarpus recognized only duct cells in control samples, whereas, in fibroadenoma tissue, it recognized duct and some stromal cells, suggesting that O-glycans-type mucin linked to proteins and mucin participate in the development of fibroadenomas.

Abstract
OBJECTIVE To evaluate the experience of a single cancer center with unusual tumors. To analyze Primary breast sarcomas (PBS). To investigate treatment and prognostic factors influencing overall survival (OS) and disease-free survival (DFS). PATIENTS AND METHODS Retrospective study of a series of 42 patients. We reviewed the clinical records and pathology slides of 42 women with PBS treated in our institution between 1970 and 2002. Log-rank tests were used to determine OS and DFS. RESULTS The median age at diagnosis was 56.9 years (24-81 years). Surgery was part of the therapeutic strategy in all the patients. Patients with angiosarcoma and those with malignant cystosarcoma constituted distinct populations. The 10-year OS and DFS rates were 53% and 55% for angiosarcoma patients and 89% and 100% for cystosarcoma patients (p=0.009 and 0.01 respectively). CONCLUSION Careful preoperative multidisciplinary assessment is required before making the decision to treat. Mastectomy is generally indicated. Axillary lymph node dissection is not indicated.

Abstract
Cystosarcoma phyllodes constitutes only 0.3-0.9% of all breast tumors. The term "sarcoma" was initially used because of its fleshy appearance, a more modern term is Phyllodes tumor (PT). The behavior of PT constitutes a spectrum from benign and locally recurrent to malignant and metastatic. In a general surgical series, 6.2% of the tumors were malignant. The microscopic appearance of PT is that of epithelial elements and connective tissue stroma. Malignancy is determined by characteristics of the stroma. The metastatic spread of malignant PT is mainly hematogenous to lung, with infrequent lymphatic involvement. Wide local excision with 2 cm margins is the treatment of choice. In 20% of both benign and malignant cases, PT will locally recur. There is no proven benefit of radiation or chemotherapy, although radiotherapy may be useful in selected cases. We present a case of a sarcomatous overgrowth in a malignant phyllodes tumor involving multiple histologic types.

Abstract
Cytological and histological findings of a rare case of a malignant phyllodes tumor (with liposarcomatous components) of the breast are presented. The atypia of the stromal cells and naked nuclei in a lesion considered benign clinically and on imaging alerted us to the possibility of a phyllodes tumor, despite the low cellularity of the preoperative fine-needle aspiration smears. The excisional biopsy was histologically diagnosed as malignant phyllodes tumor with liposarcomatous components. Peculiar atypical cells with large, pale, transparent cytoplasm, or with intranuclear chromatolytic areas similar to intranuclear cytoplasmic inclusions, in addition to atypical lipoblasts revealed in imprint smears from the excised tumor, may be important for cytopathologists to achieve a definitive cytological diagnosis, and also to observe patients over long periods for recurrences and metastasis after surgery for this rare breast tumor.

Abstract
Osteosarcomatous differentiation in phyllodes tumors is uncommon. The clinicopathologic features of 22 such cases in our files were retrospectively reviewed to evaluate the prognostic significance of this rare neoplasm. All patients were women between 40 and 83 years of age (mean, 60 years). Most (73%) presented with a palpable mass. None had prior irradiation to the breast or chest region. Patients were treated with excisional biopsy (N = 4), partial mastectomy (N = 1), or mastectomy (N = 17). All axillary nodes, dissected in 11 patients, were free of tumor. Two patients had extramammary spread at diagnosis. The neoplasms measured 1.9-15 cm (mean, 6.4 cm); 54% were grossly circumscribed or multilobulated. The osteosarcomatous component was classified as fibroblastic (N = 11), osteoclastic (N = 6), or osteoblastic (N = 5) and occupied a variable percentage of the phyllodes' stroma ranging from -25% to essentially 100% of the neoplasm. Of 21 patients with available follow-up, 11 (52%) were alive at a median follow-up of 44 months. Nine patients (43%) developed locally recurrent (N = 1) or metastatic (N = 8) disease. Metastases were clinically apparent within 1 year of diagnosis in all eight patients; seven died within 12 months of detection of initial metastasis. By univariate analysis, gross tumor size and osteosarcoma subtype significantly correlated with prognosis. In a multivariate analysis, neither of these factors were independent prognosticators. Phyllodes tumors with an osteosarcomatous component are potentially aggressive neoplasms, particularly when large (>5 cm) or associated with an osteoclastic or osteoblastic osteosarcoma. Complete excision without axillary dissection is advised.
