Objectives: To present the results of adopting CBR/FEBRASGO/SBM recommendations for breast cancer screening and diagnosis during 2020 COVID-19 PANDEMIC on mammograms (MMG), breast ultrasound (BUS), breast biopsy (BB), and cancer diagnosis (CD) rates. Methodology: Comparing by month the total number of MMG, BUS, BB (composed of fine needle, core, and vacuum procedures), and invasive and in situ cancers diagnosis (CD) performed at Redimama, a private breast unit from Belo Horizonte Brazil, that adopted CBR/FEBRASGO/SBM recommendations for breast cancer screening and diagnosis during the 2020 COVID-19 pandemic year to 2019 same period. Results: In April 2019, 391 MMG, 714 BUS, 223 BB, and 22 CD were performed, compared with 115 (29.4%) MMG, 313 (43.8%) BUS, 116 (52%) BB, and 11 (50%) CD in 2020. A continuous and fast recovery occurred along the time. In 2019 first semester, 2241 MMG, 4229 BUS, 1214 BB, and 84 CD were performed, compared with 1,903 (88.7%) MMG, 4,227 (99.2%) BUS, 1,044 (86%) BB, and 92 (109.5%) DC in 2020. In 2019, 4,424 MMG, 10,395 BUS, 3,304 BB, and 231 CD were performed, compared with 4,561 (110.79%) MMG, 11,549 (120.72%) BUS, 3,011 (91.13%) BB, and 226 (97.83%) CD in 2020. In 2019, the median size in image (T) by MMG/BUS for invasive cancers (IC) was 18.18 mm, from CD 184 (79.66%) were IC, and 47 (20.4%) ductal carcinoma in situ (DCIS) compared to a T of 18.2 mm, 191 (86.52%) IC, and 35 DCIS in 2020. Conclusion: Adopting the CBR/FEBRASGO/SBM recommendations for breast cancer screening and diagnosis results to recovery the prior pandemic levels. Recovery of MMG and BUS is faster and shows a “J” curve compared with recovery of BB and CD that shows a “´U”` curve with a delay. This strategy should be adopted in Brazil in order to maintain breast cancer screening and diagnosis.

Introduction: Lymph node tuberculosis is the most common extra-lung presentation of tuberculosis, responsible for 43% of peripheral lymphadenopathies in developing countries. The coexistence between lymph node tuberculosis and breast cancer is rare, ranging from 0.1% to 4.9%.Objective: To present a case of axillary lymph node tuberculosis due to its rare association with breast cancer. Methods: We have investigated the case of a 48-year-old woman from Congonhas, Minas Gerais, Southeastern Brazil, who presented a palpable nodule in the junction of the right upper quadrants with two years of progression, category 4B of the Breast Imaging Reporting and Data System (BI-RADS) on mammography and ultrasound, with core needle biopsy compatible with benignancy. No axillary lymphadenopathy was identified. Case report: The patient underwent resection of the right breast nodule with safety margins due to disagreement between biopsy and imaging tests. Anatomopathological examination was consistent with luminal B invasive ductal carcinoma, measuring 1.6 cm. The patient was submitted to sentinel lymph node biopsy using patent blue in the right axilla. Anatomopathological analysis revealed tuberculous lymphadenitis. Chest computed tomography showed pulmonary nodules. The patient received adjuvant radiotherapy and tamoxifen, as well as antituberculous antibiotics, with regression of pulmonary nodules. The final staging was pT1cN0M0- IA. Discussion: Most cases of coexistence between these diseases involve tuberculous lymphadenitis with or without neoplastic lymph node involvement. Some reports indicate that the involvement by tuberculosis does not prevent neoplastic proliferation. Before starting chemotherapy, tuberculosis must be treated to avoid the immunosuppressive effect that can cause a spread of tuberculosis. Conclusion: Despite the rare coexistence of these diseases, we should not rule out this possibility, especially in endemic tuberculosis areas. Also, an accurate diagnosis prevents incorrect staging and can spare the patient from a more aggressive treatment.

Introduction: Sarcomas are a heterogeneous group of malignant neoplasms and represent less than 1% of neoplasms among adults; 80% of these cases originate in soft tissues. The liposarcoma corresponds to 20% of the subtypes of sarcoma in adults. Objectives: To present a rare case of liposarcoma of the breast. Methods: We studied the case of A.N.R, a 54-year old male patient, from Belo Horizonte, Minas Gerais, presenting a progressive growth nodule in the right breast. Mammography and breast ultrasound suggested lipoma. Core-needle biopsy of the nodule in the right breast was performed, and the anatomopathological was compatible with lipoma. Case report: Due to the progressive growth, the patient was submitted to nodule resection, with safety margins. Anatomopathological and immunohistochemical of the surgical piece were compatible with well-differentiated liposarcoma. The patient was followed-up by the oncologist and had a staging computed thoracic and abdominal tomography without changes, thus not indicative of adjuvant treatment. Discussion: Liposarcoma presents as a painless mass, of progressive growth, being more common in extremities and the retroperitoneum. When the well-differentiated morphological subgroup is located in the extremities and the torso, its excision is curative, and its metastatic potential is null in comparison to other locations; however, it is not recommended to underestimate the risk of local recurrence. Conclusion: even though the prevalence of benign lesions in soft tissues is higher than malignant lesions, it is important to consider a differential diagnosis of malignancy when the behavior and presentation of the tumor are atypical (deep location to the muscle fascia, larger than 5 centimeters, progressive growth), therefore leading to better surgical and therapeutic planning and to a more accurate treatment for the patient.
