Cancer in the Grand Libreville, Gabon (2013-2017).

Background: The burden of cancer is expected to nearly double in sub-Saharan Africa over the next 20 years. In Gabon, the primary population-based cancer registry to be established is located in the Grand Libreville. This study presents cancer incidence rates covering the first 5-year period of registration in this region.

HPV genotypes in high-grade cervical lesions and invasive cervical carcinoma detected in Gabonese women.

Background: Cervical cancer is the third most common cancer among women worldwide, but particularly affects women living in sub-Saharan Africa. Screening and vaccination programs are two prevention approaches that can reduce cervical cancer incidence. However, effective vaccination campaigns require better knowledge of the prevalence of the main human papillomavirus (HPV) genotypes reported in high-grade neoplastic lesions and invasive carcinomas in women.

Molecular analysis of human Papillomavirus detected among women positive for cervical lesions by visual inspection with acetic acid/Lugol's iodine (VIA/VILI) in Libreville, Gabon.

Background: The human papillomavirus (HPV) is the causative agent of cervical cancer, which is the leading cancer-related cause of death for women in Sub-Saharan Africa. In 2013, the Gabonese Ministry of Health and the Sylvia Bongo Ondimba Foundation implemented cervical cancer screening programs based on the detection of cancerous lesions by visual inspection with acetic acid and/or Lugol's iodine (VIA/VILI). This pilot study was set up to determine the HPV profile and analyze the nucleotide sequence variation of HPV16 circulating in patients with cervical abnormalities detected by VIA/VILI testing.

Morphologic criteria associated with Trichomonas vaginalis in liquid-based cytology.

Objective: To evaluate the morphologic criteria associated with Trichomonas vaginalis on Cytyc (Marlborough, Massachusetts, U.S.A.

Low-grade adenosquamous carcinoma of the breast--A case report with a BRCA1 germline mutation.

Breast cancers occurring in women with germline BRCA1 mutations tend to fall into the category of triple-negative or basal-like phenotypes, such as metaplastic carcinoma. Low-grade adenosquamous carcinoma of the breast is a rare variant of metaplastic carcinoma. We present the case of a 49-year-old woman with a past medical history of invasive ductal breast carcinoma 13 years ago, and who was recently diagnosed as having a low-grade adenosquamous carcinoma in the same breast.

Angiolipoma of the breast in a male: a case report and review of the literature.

Objective: Angiolipoma is an unusual variant of lipoma involving subcutaneous tissues on trunk and extremities. This tumor is rarely described in the breast and particularly in breast male.

Case Report: We report here the case of angiolipoma of the breast in a 55-year-old man complained of tenderness in the left breast.

High prevalence of high-risk human papillomavirus infection among women with Trichomonas vaginalis infection on monolayer cytology.

Objective: To evaluate the risk of high-risk human papillomavirus (HPV) infection in women with Trichomonas vaginalis infection, and the reason remains unclear.

Methods: A total of 40,000 liquid-based cytology specimens were tested from 2005 to 2008. Among these, high-risk HPV testing using the hybrid capture II assay was performed in positive cases of T.

Lymph node involvement in multicystic peritoneal mesothelioma.

Multicystic peritoneal mesothelioma is an uncommon lesion most frequently encountered in women of reproductive age. Although the pathologic characteristics have been documented, the lymph node status associated with this pathology, the etiopathogenesis and prognosis of which remain unclear, is unknown. We report here the case of a 35-year-old woman with a 5.

Ovarian involvement by desmoplastic small round cell tumor with leydig cell hyperplasia showing an unusual immunophenotype (cytokeratin negative, calretinin and inhibin positive) mimicking poorly differentiated sertoli leydig cell tumor.

Desmoplastic small round cell tumor (DSRCT) is a rare aggressive tumor primarily involving serosal surfaces in adolescents and young men. Diagnosis is based on specific clinicomorphologic, immunohistochemical, and genetic features. We report here a variant of DSRCT involving the ovaries that mimics the Sertoli-Leydig cell tumor in a 21-year-old woman complaining of abdominal pain.

Immediate surgical resection of residual microcalcifications after a diagnosis of pure flat epithelial atypia on core biopsy: a word of caution.

The entity of pure flat epithelial atypia remains a challenge due to controversy of the surgical management of residual microcalcifications after core needle biopsies. This study aims to assess the morphological data observed in immediate surgical resection specimen of residual microcalcifications after a diagnosis of pure flat epithelial atypia on mammotome core biopsy. Sixty-two mammotome core biopsy with a diagnosis of pure flat epithelial atypia (flat epithelial atypia without associated atypical ductal hyperplasia, in situ and/or invasive carcinoma) were identified.

Accuracy of lymph nodes cell block preparation according to ultrasound features in preoperative staging of breast cancer.

To analyse the correlation between axillary ultrasonography (US), cell block (CBs) preparation, and histological diagnosis of lymph nodes from patients with primary breast cancer with the intention to assess the accuracy of cell block (CB) technique in preoperative staging. We tested a series of 26 patients who underwent axillary cell blocks from ultrasound guided fine-needle aspiration with histologic follow-up (axillary lymph nodes dissection). The specificity of axillary cell block was 100% vs.

Primary ovarian carcinoid tumor with luteinized stromal cells.

Background: Primary ovarian carcinoid tumors are rare. Distinct histologic patterns have been described in the literature as insular, trabecular, mucinous and mixed types.

Case Report: We describe a case of 71-year-old woman diagnosed with a left ovarian tumor.
