Cystic squamous metaplasia in a giant benign phyllodes tumor of the breast: a case report.

Phyllodes tumor is a rare tumor of the breast, which encompasses both stromal and epithelial components. In these components, metaplastic changes can be observed occasionally. We report the case of a 51-year-old woman nulligest menopaused who presented a huge mass, largely ulcerated in her right breast. The radiological examination revealed a large tumor with microcalcifications classified as Breast Imaging and Reporting Data System Category 5. The patient undergone right mastectomy and the histological analysis revealed benign phyllodes tumor with cystic squamous metaplasia. Therefore, we aim to present this uncommon event occasionally occurring in phyllodes tumor of the breast.

Unusual case of parietal metastasis from papillary thyroid carcinoma: a case report.

Parietal metastasis is a very rare secondary location of papillary thyroid carcinoma. It associated with poor prognosis. We report a case of a 61-year-old woman with parietal metastasis from papillary thyroid carcinoma. The patient presented a parietal nodule on the back. In her past history, she had been diagnosed papillary thyroid carcinoma after total thyroidectomy and also reoperated for local recurrence. The CT scan performed has revealed metastasis to the lungs, bones, lymph nodes and adrenal glands. The parietal nodule was excised and submitted for histopathological examination. The histologic and immunohistochemical findings confirmed the thyroid origin. Although papillary thyroid carcinoma is a relatively indolent tumour, it can exhibit an unusual metastatic behaviour.

Ovarian cystic tumor composed of brenner tumor and stroma ovarii.

INTRODUCTION: Brenner's tumors are transitional cell ovarian tumors composed of mature cells similar to urothelial cells forming nests within a fibromatous stroma. CASE REPORT: In this observation we report the case of a brenner's tumor diagnosed in a 63 year old female patient. The positive diagnosis was difficult to retain. DISCUSSION: Brenner tumors are rare fibroepithelial ovarian tumors, representing 1 to 2 % of all ovarian tumors. They are almost always benign. CONCLUSION: The treatment is essentially surgical and the indication of chemotherapy remains debatable.
