Occult breast cancer (OBC) is characterized by metastatic presentation of undetectable breast tumor on imaging exams. OBC is a rare disease (accounting for 0.3% to 1.0% of all breast cancers) that represents a major diagnostic challenge. The aim of this study was to report a case of OBC with primary presentation of multiple cutaneous metastases with subsequent emergence of bone metastasis. A 70-year female patient had multiple cutaneous metastatic lesions in the left cervical region, left breast, left axillary region, left subscapular region, in three chirodactylus of the right hand and three chirodactylus of the left hand. Imaging tests (mammogram, ultrasonography and magnetic resonance imaging of the breast) did not show alterations. Biopsy, histology sections and immunohistochemistry of the left cervical cutaneous lesion were compatible with OBC. After two years of anastrozole treatment (1mg/day), there was regression of all cutaneous lesions and stabilization of bone metastasis. OBC has a better prognosis. It may exhibit spontaneous regression or respond to less aggressive treatment strategies, as described in this case.

OBJECTIVE: Triple-negative breast cancer (TNBC) is characterized by lack of estrogen receptor, progesterone receptor, and human epidermal growth factor receptor 2 (HER2) expression and accounts for 15-20% of all breast cancers. This study aims to analyze prognostic factors related to a reduction in overall survival (OS), disease-free survival (DFS), and risk of mortality and recurrence in TNBC.METHODS: This is a retrospective observational cohort study. Medical records of 532 patients with breast cancer diagnosed from 2007 to 2020 were analyzed. Of these patients, 93 (17%) were women with TNBC. Ten medical records were excluded, and the final sample was composed of 83 women with TNBC. OS and DFS were estimated by the Kaplan-Meier model. Univariate analysis (log-rank test) and multivariate analysis (Cox regression) were used to examine prognostic factors related to a statistically significant reduction (p<0.05) in OS and DFS and increased risk of mortality and tumor recurrence.RESULTS: Smoking, advanced clinical stage, larger tumor size, angiolymphatic invasion, positive sentinel lymph node, axillary node involvement, higher cancer burden, surgical treatment with mastectomy, and recurrence were related to a significant decrease in OS and/or DFS and increased risk of mortality and/or recurrence in TNBC. The 10-year OS and DFS was around 61 and 65%, respectively. CONCLUSIONS: Advanced clinical stage, positive sentinel lymph node, axillary node involvement, surgical treatment with mastectomy, and higher residual cancer burden were related to a significant reduction in OS and DFS and increased risk of mortality and recurrence in TNBC.

Background: Poland’s syndrome is a rare congenital non-inherited anomaly that usually manifests itself during adolescence and is characterized by absence or deficient development of one of the breasts. To our knowledge, no case of breastfeeding after reconstruction surgery in patients with Poland’s syndrome has been described. Case Report: A 22-year-old female patient with Poland’s syndrome underwent breast reconstruction. The procedure performed consisted of rotation of a myocutaneous flap harvested from the ipsilateral latissimus dorsi muscle, which was subsequently attached to the anterior thoracic wall to create a pouch and place a 300-ml round textured cohesive silicone gel-filled breast implant. 5 years later the patient got pregnant, and 1 year after delivery she is still breastfeeding normally with both breasts. Conclusion: Reconstruction surgery with the latissimus dorsi muscle and a prosthesis was shown to be a potential and safe solution to achieve improvement of breast symmetry and to provide confidence and comfort in relation to self-image and, moreover, the ability to breastfeed.

Malignant breast neoplasia is the main cause of cancer mortality in women in Brazil, after non-melanoma skin cancer, and about 5 to 10% of these cases are associated with family inheritance; BRCA1 and BRCA2 genes are the most frequently mutated. In this sense, there has been a paradigm shift in medical practice regarding breast cancers in recent years, with the implementation of risk-reducing surgical procedures, such as bilateral mastectomy and salpingo-oopherectomy, which still have controversies in the indication, in addition to fears and sufferings of patients, before and after the procedure. A 54-year-old female patient has been undergoing routine examinations since 2009 (49 years), as she has a family history of breast cancer. In May 2014 (54 years old), the patient underwent genetic research, discovering the pathogenic 648delT mutation in heterozygosity in the BRCA1 gene. Although complementary exams did not indicate any neoplasia, the patient wanted to undergo risk-reducing surgery. After interprofessional discussion with the patient, bilateral risk-reducing mastectomy and salpingo-oophorectomy were performed. The patient had a postoperative infection, and one of the silicone prostheses was removed from her breast. In 2015 (55 years old), she underwent a new prosthesis inclusion, evolving without complications. Currently, she is being followed up and without evidence of active cancer disease. Despite the complication with the prosthesis, there was an improvement in psychological aspects that bothered her, referring to a reduction in anxiety and fear of cancer. Although beneficial, risk-reducing mastectomy has associated risks, especially in patients with advanced age and comorbidities. However, with an appropriate approach and focused on the complexities of each person, it is possible to provide the patient with a better overall psychological experience, as demonstrated in this case reported.
