Paget’s disease of the breast is a rare cancer. This typical clinical case illustrates the different epidemiological, clinical, histological, therapeutic, and evolving aspects of the disease. We report a case of Paget’s disease in a 43-year-old woman who presented eczema of the nipple. Mammography and ultrasounds did reveal a lesion in situ. The patient was scheduled for mastectomy and sentinel node biopsy. She had chosen a radical bilateral surgery. The histological diagnosis was Paget’s disease of the breast with a carcinoma in situ. There was no metastasis in either of the sentinel nodes. Paget’s disease must be considered with the presence of a persistent eczematous involvement of the nipple, which does not respond to local treatment. Ultrasounds, mammography, and magnetic resonance imaging can allow searching an underlying cancer and guiding the surgical management. There is no evidence at this time that one of the two surgical techniques (conservative or mastectomy) would improve survival. The prognosis depends on the presence of a palpable mass and the invasiveness of the cancer.

We report a case of renal metastases from prostate cancer to show that the possibility of tumor metastasis, although rare, should always be considered in the differential diagnosis of renal mass.

Objective: In this article, we present two case reports. The first case was a malignant germ cell tumor of the right ovary in a 23-year old woman and the second case was a bilateral undifferentiated granulosa cell tumor in a 71-year old woman. The aim of these reports is to illustrate the interest of the immunohistochemical analysis to define the correct diagnosis, to better classify these ovarian tumors and improve their management.Methods: In this study, we report two cases. The first case concerns a 23-year old woman (A) with a mixed germ cell tumor of the right ovary [dysgerminoma (75%), yolk sac tumor (20%), and a mature teratoma (5%)], and the second case concerns a 71-year old woman (B) with a bilateral non-differentiated and necrotic granulosa cell tumor of both ovaries. The staging system was used according to both the classifications: International Federation of Gynaecology and Obstetrics 1987 for ovarian cancer and TNM code 2009.Results: The immunostaining establishes the malignancy and the immunochemistry contributes to confirm effectively the right diagnosis (Tables 2 and 3).Conclusion: An immunohistochemical analysis is mandatory for the choice of chemotherapy to obtain a better response of the disease and improve the survival prognosis. The efficiency of the chemotherapy authorizes a conservative surgery including a unilateral salpingo-oophorectomy preserving fertility (A). Concerning the non-dysgerminoma tumor (B), and after a surgical staging and debulking, chemotherapy was recommended. The type of tumor and its histological feature conditioned the choice of treatment. The benefit of the immunohistological analysis in this case allowed the right adjuvant treatment.

The presence of tumor cells can be identified in the lymph node when metastasis has occurred from the primary cancer site into the lymph node (1) If the sentinel lymph node ganglion is negative for the presence of tumor cells at the time of histological examination, the other lymph nodes are also negative in 99% of cases. If no tumor cells are identified in the sentinel lymph node ganglion by histological examination, the other lymph nodes are also negative for the presence of tumor cells in 99% of cases. The sentinel lymph node advantageously replaces axillary dissection as a staging method in breast cancer T1 and T2 (2). Approximately 40% of breast cancers metastasize to axillary lymph nodes and metastatic extension depends on disease stage. Sentinel lymph nodes are affected in the following stages: T1a (4.3%), T1b (19.5%), T1c (23.8%), T2 (48.9%), T3 (66.7%).

Verrucous carcinoma of the vulva is a rare lesion (1). Affecting essentially postmenopausal women, this lesion is a distinct and particular entity in vulval carcinoma classification and its scalability is uncertain and unpredictable. Here, we present a case concerning a 48-year-old patient, without follow-up after a condyloma acuminate of the vulva (large left lip). The origin of this case will be discussed in this article. The treatment decided was only surgical. A review of literature shows the rarity of this lesion of the female genital tract.
