    Uterine myometrial mature teratoma presenting as a uterine mass: a review of literature.
    BMC Clin Pathol 2016 22;16. Epub 2016 Mar 22.
    Department of Obstetrics and Gynecology, Catholic University of Health and Allied sciences, P.O.BOX 1464, Mwanza, Tanzania.
    Background: Teratomas are a germ cell tumors composed of two or more tissues which originate from ectoderm, endoderm or mesoderm. These tumors commonly arise from the ovary although other extragonadal sites can be involved, especially in children.

    Case Presentation: We report a case of a 21-year-old female of Sukuma ethnicity from the northern region of Tanzania who presented with abdominal pain and distension, fever, and abnormal vaginal discharge for the previous three weeks. Read More

    Bone metastasis from malignant phyllodes breast tumor: report of two cases.
    BMC Clin Pathol 2016 29;16. Epub 2016 Feb 29.
    Department of Pathology, Mohamed V military Hospital, Hay Riad, Faculty of Medicine, Mohamed V University, BP10000 Rabat, Morocco.
    Background: Phyllodes tumors are rare fibroepithelial tumors accounting for less than 1 % of all breast neoplasms. They are malignant in 20 % of cases. Only a few cases of malignant phyllodes tumors metastatic to bone have been reported. Read More

    Histopathological characterization of corrosion product associated adverse local tissue reaction in hip implants: a study of 285 cases.
    BMC Clin Pathol 2016 27;16. Epub 2016 Feb 27.
    Department of Pathology and Laboratory Medicine, Hospital for Special Surgery, 535 East 70th Street, New York, NY 10021 USA.
    Background: Adverse local tissue reaction (ALTR), characterized by a heterogeneous cellular inflammatory infiltrate and the presence of corrosion products in the periprosthetic soft tissues, has been recognized as a mechanism of failure in total hip replacement (THA). Different histological subtypes may have unique needs for longitudinal clinical follow-up and complication rates after revision arthroplasty. The purpose of this study was to describe the histological patterns observed in the periprosthetic tissue of failed THA in three different implant classes due to ALTR and their association with clinical features of implant failure.

    Quantitative assessment of placental morphology may identify specific causes of stillbirth.
    BMC Clin Pathol 2016 9;16. Epub 2016 Feb 9.
    Institute of Human Development, Faculty of Medical and Human Sciences, University of Manchester, Oxford Rd, Manchester, M13 9PL UK ; Maternal and Fetal Health Research Centre, 5th floor (Research), St Mary's Hospital, Oxford Road, Manchester, M13 9WL UK.
    Background: Stillbirth is frequently the result of pathological processes involving the placenta. Understanding the significance of specific lesions is hindered by qualitative subjective evaluation. We hypothesised that quantitative assessment of placental morphology would identify alterations between different causes of stillbirth and that placental phenotype would be independent of post-mortem effects and differ between live births and stillbirths with the same condition.

    Primary leiomyosarcoma of the submandibular gland: a case report.
    BMC Clin Pathol 2015 15;15:22. Epub 2015 Dec 15.
    Department of Pathology, Mohamed V Military Hospital, Hay Riad, Rabat Morocco.
    Background: Leiomyosarcoma is a rare malignant mesenchymal tumor that represents 5-7 % of all soft tissue sarcomas. The occurrence of this tumor in the salivary glands is exceptional. Only five cases are reported in the submandibular gland. Read More

    Expression of a-Tocopherol-Associated protein (TAP) is associated with clinical outcome in breast cancer patients.
    BMC Clin Pathol 2015 9;15:21. Epub 2015 Dec 9.
    Department of Pathology, University of Rochester Medical Center, Rochester, NY 14642 USA.
    Background: The role of vitamin E in breast cancer prevention and treatment has been widely investigated, and the different tocopherols that comprise this nutrient have been shown to have divergent associations with cancer outcome. Our previous studies have shown that α-Tocopherol-associated protein (TAP), a vitamin E binding protein, may function as a tumor suppressor-like factor in breast carcinogenesis. The current study addresses the association of TAP expression with breast cancer clinical outcomes. Read More
