[Reversed polarity high-cell carcinoma of the breast: A case report].

Reverse polarity high-cell carcinoma of the breast, formerly known as reverse polarity solid papillary carcinoma, is a rare entity recently introduced into the latest edition of the WHO classification of breast tumors. Its phenotype is triple-negative, and its diagnosis difficult. Although few cases have been reported in the literature, knowledge of this breast tumor is essential to distinguish it from other triple-negative carcinomas, which have a poorer prognosis.

Prevalence and Prognostic Value of HPV among Tunisian Patients with Laryngeal Cancer and Relationship between DNA HPV and p16, IGF-1R, Survivin, p53 Expressions.

Objectives: Tobacco and alcohol are the main etiological factors common to laryngeal cancers. However, the Human Papilloma Virus (HPV) constitutes an alternative risk factor according to several studies. In Tunisia, despite the annual increasing incidence of laryngeal squamous cell carcinoma (LSCC), the prevalence and prognostic significance of HPV have never been explored.

The Prognostic Significance of IGF-1R and the Predictive Risk Value of Circulating IGF-1 in Tunisian Patients with Laryngeal Carcinoma.

The aim was to evaluate the clinical impact of IGF-1/IGF-1R in Tunisian laryngeal carcinoma. A high IGF-1R immunohistochemical expression was found in our series (81.43%).

MARCKS protein overexpression is associated with poor prognosis in male breast cancer.

Background: Male breast cancer (MBC) is a rare and aggressive disease. Thus, identification of new therapeutic targets is crucial.

Objective: Our objective was to evaluate the protein expression of MARCKS (Myristoylated Alanine-Rich C-Kinase Substrate) in MBC and to investigate its prognostic value.

Expression Profile of Survivin and p16 in Laryngeal Squamous Cell Carcinoma: Contribution of Tunisian Patients.

The objective of this study was to evaluate the expression of survivin and p16 in laryngeal squamous cell carcinoma (LSCC) in order to analyze their pathogenesis and prognostic significance in Tunisian patients. A total of 70 patients with LSCC collected at the Salah Azaiez Cancer Institute of Tunis were retrospectively evaluated. Expression of survivin and p16 was examined using immunohistochemistry, and the correlations with clinicopathological parameters, overall survival (OS), and disease-free survival (DFS) were statistically evaluated.

Submandibular lipoblastoma: Case report of a rare tumor in childhood.

Lipoblastoma is a rare, benign tumor usually occurring in childhood. It is essentially localized in the extremities and trunk, with few cases reported in the neck. We report the case of a 2-year-old girl with a rapidly enlarging, painless neck mass.

Forkhead box M1 (FOXM1) expression predicts disease free survival and may mediate resistance to chemotherapy and hormonotherapy in male breast cancer.

Background: Male breast cancer (MBC) is a rare and neglected disease. Prognostic and predictive factors in MBC are extrapoled from trials conducted on its female counterpart.

Objective: Since the relationship between the transcription factor Forkhead box M1 (FOXM1) expression and the clinical response to chemotherapy and hormonotherapy in MBC remains unknown, we sought to investigate the predictive value of FOXM1 in MBC.

Clinico-pathological and prognostic findings on 27 cases of medullary thyroid carcinoma.

Introduction: Medullary thyroid carcinoma is a rare tumor accounting for less than 10% of thyroid neoplasm. This tumor is characterized by important histological polymorphism which makes morphological diagnosis difficult and immunohistochemical study often necessary.

Objective: We aim to perform a retrospective review of clinical and pathological characteristics of medullary carcinoma.

Comparative study of two complementary proliferation markers in 200 breast carcinomas: Ki67 and mitotic index.

Background: The evaluation of the proliferation in the mammary carcinomas provides useful prognostic and predictive information for subsequent management. The purely morphological evaluation of proliferative activity was represented by the evaluation of mitotic index. New analytical methods were gradually developed and performed.

Mucinous breast carcinoma a rare entity to be known: clinico-pathological study of 48 cases.

Background: Mucinous carcinoma is a particular type of breast cancer characterized by the presence of extracellular mucin and is linked with a more favorable prognosis than invasive breast carcinoma of no special type. It accounts for 1 to 7% of all breast cancers. We propose in this work to study at first the clinic-pathological characteristics and the evolution of 48 cases of mucinous carcinomas.

Expression profile of biomarkers altered in papillary and anaplastic thyroid carcinoma: Contribution of Tunisian patients.

Aims: The objective of this study was to compare the protein expression profile between well-differentiated (papillary) and undifferentiated (anaplastic) thyroid carcinoma in Tunisian patients.

Methods: This first Tunisian retrospective study concerned data of 38 thyroid cancer cases (19 papillary carcinoma PTC and 19 anaplastic carcinoma ATC) collected at Salah Azaiez Institute of Tunisia. Immunohistochemistry was used to evaluate tumor expression of different molecular markers (p53, Ki67, E-cadherin, cyclin D1, bcl2, S100 and Her-2).

Descriptive analysis of molecular subtypes in Tunisian breast cancer.

Aim: The objective is to report the correlation between pathology and molecular subtype classifications of breast cancer in Tunisian women.

Methods: This retrospective study concerned data of 966 breast cancer cases collected from 2007 to 2009 at Salah Azaiz Institute of Tunis. These cases were classified by an immunohistochemistry test for estrogen and progesterone receptors and human epidermal growth factor receptor 2 (HER2) status in the four molecular subtypes, namely luminal A, luminal B, HER2+ and triple negative.

Malar bone metastasis revealing a papillary thyroid carcinoma.

Papillary thyroid carcinoma is the most common form of differentiated thyroid carcinoma. It is generally confined to the neck with or without spread to regional lymph nodes. Metastatic thyroid carcinomas are uncommon and mainly include lung and bone.

Prognostic evaluation of p53, heat shock protein 70, Ki67, and CD34 expression in cancer of the tongue in Tunisia.

Objectives: Oral tongue cancer remains an aggressive tumour in Tunisia, and patients often present with locally advanced disease, leading to high mortality. The molecular pathway of its tumorigenesis is not yet understood. This study aimed to assess the biologic significance of p53, heat shock protein 70 (Hsp70), Ki67, and CD34 and their influence on survival in patients with tongue cancer.

[Squamous cell carcinoma arising in a papillary carcinoma of the thyroid: a case report].

Background: primary squamous cell carcinoma (scc) of the thyroid is a rare malignant tumor that needs to be distinguished from other neoplasms. Cases of papillary carcinoma merging in association with squamous cell carcinoma are extremely rare.

Aim: the characteristics of such association will be studied herein through a review of literature.
