Heparin-induced thrombocytopaenia (HIT) is a life and limb-threatening acquired autoimmune complication of heparin-based treatment, characterised by thrombocytopaenia and thrombosis. We present a case of a 77-year-old female with concomitant metastatic ovarian and breast cancer who presented to our institution with worsening shortness of breath. She had been diagnosed with acute pulmonary embolism 1 month earlier that was treated with therapeutic low molecular weight heparin (LMWH). In view of her worsening symptoms, CT imaging was performed. This demonstrated significant progression of the bilateral pulmonary emboli and new mural thrombosis of the thoracic aorta, despite being compliant with therapeutic anticoagulation. She had also developed thrombocytopaenia since commencing LMWH, which raised the clinical suspicion of HIT syndrome. The HIT pre-test probability score was intermediate and LMWH was immediately discontinued pending further investigation. She was commenced on rivaroxaban, a direct oral anticoagulant, and her platelet count soon recovered. Laboratory testing was strongly positive on both immunological and functional assays, thus confirming a diagnosis of HIT syndrome. A repeat CT scan 3 weeks later showed a reduction in the overall thrombus load. Whilst venous thrombosis is observed in as many as half of patients with HIT, arterial thrombosis is a far less common event. Furthermore, arterial involvement usually affects the distal vessels with significant atherosclerotic burden and typically presents as acute limb ischaemia or ischaemic stroke. Aortic thrombosis, as in this case, is a rare complication of HIT syndrome.

We present a case of a 63-year-old woman with an acute history of abdominal distension and shortness of breath. She had no risk factors for liver disease though her prior medical history was positive for breast carcinoma, in remission for 14 years. Examination and investigations were initially consistent with decompensated cirrhosis, thought to be due to subclinical autoimmune hepatitis. Imaging revealed hepatic contour irregularity, atrophy of the liver parenchyma and numerous lesions highly suggestive for multifocal hepatocellular carcinoma. Surprisingly, tissue histology revealed no evidence of cirrhosis, but recurrence of breast cancer which had mimicked cirrhosis. Pseudocirrhosis may be indistinguishable from true cirrhosis without histopathology. It has previously been linked to chemotherapy-induced hepatic injury and nodular regenerative hyperplasia, although our case illustrates an uncommon pathophysiology. Pseudocirrhosis often represents a poor prognosis even with a good baseline performance status, and early involvement of palliative care specialists may be advisable.

A 45-year-old Asian woman was presented with fever, easy fatigability, shortness of breath, cervical and axillary lymphadenopathy and other signs and symptoms of anemia. After all the baseline work-up, the patient was investigated for Mono-coombs C3d levels, which were elevated, suggesting the diagnosis of Cold autoimmune hemolytic anemia (Cold AIHA). An Ultrasound-guided true-cut biopsy was done to determine the primary cause associated with it, which showed the presence of tumor cells arranged in cords and clusters. They have dark staining cells with mitotic activity, suggestive of breast carcinoma as an association of Cold AIHA. Estrogen receptor (ER), progesterone receptor (PR) and human epidermal growth factor receptor 2 (HER2) were sent, which came out to be positive. So, the patient was diagnosed with Cold AIHA in association with triple-positive breast cancer.

The novel coronavirus disease (COVID-19) arises from the virus SARS-CoV-2 which is similar to the original SARS virus. The most common symptoms of the COVID-19 infection are fever, coughing and shortness of breath. According to the current data, the primary mode of transmission for the COVID-19 virus is between people through respiratory droplets and contact routes. The virus may lead to worse respiratory complications, including pneumonia, especially in older patients and patients with pre-existing illnesses, such as cancer. Cancer patients are at a significantly higher risk of getting infected with COVID-19 since their immune system can be compromised and that reality has to do with both that they have cancer and that they are on therapy for their cancer. COVID-19 crisis has impacted every aspect of the practice, including outpatient, elective, wards, emergency care, conferences, teaching and research. We should make sure cancer patients on active treatment are treated appropriately. In this review, we tried to explain how to prevent the negative effects of the COVID-19 pandemic on the diagnosis and treatment of breast cancer patients.

A 59-year-old incarcerated woman who was diagnosed with invasive ductal carcinoma in 2016 was brought in for evaluation of the breast cancer. Upon evaluation of the computed tomography chest for breast cancer restaging, diffuse bilateral ground glass opacities and a reverse halo sign in the right lower lobe concerning for atypical viral pneumonia were discovered. The patient was afebrile, had an oxygen saturation of 100%, and denied chest pain as well as shortness of breath. On physical exam, she exhibited decreased breath sounds bilaterally and expiratory wheezing. She later received a COVID-19 test, which came back positive. Infection with the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2, also known as COVID-19) may remain asymptomatic in the initial phase, leading to under-recognition and incidental detection on procedures for standard clinical indications. Hospitals, in particular diagnostic imaging services, should prepare accordingly in regard to health precautions while keeping in mind the potential discrepancies between clinical presentation and resultant radiologic patterns. This awareness should be heightened in patients at higher risk (ie, prisoners). Furthermore, by acting upon the incidental detection of this virus during its early stages, subsequent steps could help prevent the spread of the virus.

In the absence of clear interstitial invasion, encapsulated papillary carcinoma (EPC) of the breast may be attributed to an extremely good prognosis if handled similarly to ductal carcinoma in situ (DCIS) with suitable local treatment. Here, we report our experience with a case of EPC of the breast that presented with carcinomatous pleuritis and lymphangitis carcinomatosa postoperatively, which rapidly resulted in a poor outcome. A 67-year-old woman was diagnosed with DCIS of the left breast and underwent left partial mastectomy and sentinel lymph node biopsy. EPC was diagnosed because the pathological examination showed no sign of interstitial infiltration. Postoperative radiation therapy was performed. Five years and 9 months postoperatively, the patient began experiencing cough and shortness of breath on exertion. Imaging showed right pleural effusion and consolidation of the lung field, but nothing suggesting local recurrence in the preserved left breast, local lymph nodes, or opposite breast was observed. Postoperative recurrence of breast cancer, carcinomatous pleuritis, and lymphangitis carcinomatosa were diagnosed based on the results of pleural fluid cytology. One month later, multiple brain metastases were found, and the patient died of the primary disease 5 months after recurrence. After surgery for EPC without clear interstitial infiltration, there was a small possibility of a poor outcome from distant metastasis. Therefore, although distant metastasis is uncommon, regular examination and testing should be performed.
