The paper describes a clinical case of surgical treatment in a female patient with radiation-induced pleural fibrosarcoma. in 1990 due to lymphoepithelial thymoma, she underwent anterior superior mediastinal mass removal, followed by radiotherapy in a total focal dose of 60 Gy. 25 years later, an examination revealed an anterior superior mediastinal mass, a morphological examination diagnosed fibrosarcoma G2.

Supernumerary nipples can be found in approximately 1 % of women. During the second and the third months of embryonic development when the regression of ectodermal thickening of mammary line takes place, incomplete regression with remaining of some foci may occur. These foci can further develop into a supernumerary breast or a supernumerary nipple. In this article, we would like to present five cases of supernumerary nipples. In 80% of cases, there was a single unilateral supernumerary nipple located along the right mammary line. In all the described cases this minor defect was efficiently excised for cosmetic purposes.

Acanthosis nigricans (AN) is characterized by hyperpigmented, thickened skin plaques with a velvety texture. The histology of these lesions shows hyperkeratosis and dermal papillomatosis. According to the clinical data the key role in the development of acanthosis nigricans belongs to an excessive concentration of growth factors. Such condition is ofparticular interest because of its association with internal malignancies. Its malignant form is often associated with gastric adenocarcinoma (55-61%), though coexistence with a variety of other malignancies (ovarian cancer, endometrial carcinoma, bladder cancer, etc.) has been reported. Clinical case of patient with AN and coexisting breast cancer and hepatocellular carcinoma is presented. The severity of skin manifestations improved after chemotherapy, mastectomy and radiation therapy. However, skin hyperpigmentation relapsed after development of the hepatocellular carcinoma and the progression of the primary tumor. An underlying malignancy should be suspected in each case of AN.
