Paget disease (PD) of the nipple with coexisting intraductal (DCIS) and invasive carcinoma of the breast comprises 0.6-1.8% of all malignant epithelial neoplasms of this organ. Unlike invasive ductal carcinoma, there are many controversies concerning histological features of PD and the significance of the immunohistochemical characteristics of this neoplasm, which limits the optimal treatment protocols. Therefore, we decided to verify the immunohistochemical markers of PD basing on the retrospective analysis of postoperative material from 69 patients treated surgically. Microscopic examination revealed partial (7 cases) or total (62 cases) replacement of the squamous epithelium of the nipple with nests of atypical glandular cells spreading in an area ranging from 0.2 to 2.5 cm. DCIS coexisting with the PD lesions was present in all examined patients, and infiltrating carcinoma occurred in 31 (44.9%) patients. Both intraepidermal and DCIS components presented c-erbB2 overexpression. Positive estrogen and progesterone receptor staining was observed only in 7 (10.1%) and 2 (2.7%) tumours, respectively. Ki-67 proliferation index of PD cells ranged from 10% to 30%, whereas in DCIS it varied from 4% to 20%. The value of Ki-67 index exceeding 25% in the intraepidermal component of PD was associated with worse overall survival rate.

Extraskeletal osteosarcoma (ESOS) represents a rare soft tissue entity, accounting for ⁓1% of all soft tissue malignancies. It is generally considered to have an even worse prognosis than bone osteosarcoma, therefore detailed investigations and proper treatment are required. ESOSs arising in the subcutaneous tissue are even rarer than the ones positioned in deep tissues, and they are considered to have far better outcomes.

Background: The majority of respiratory syncytial virus (RSV) infections in young children are managed in primary care, however, the disease burden in this setting remains poorly defined.
Methods: We did a prospective cohort study in primary care settings in Belgium, Italy, Spain, the Netherlands, and the UK during the RSV seasons of 2020-21 (UK only; from Jan 1, 2021), 2021-22, and 2022-23. Children aged younger than 5 years presenting to their general practitioner or primary care paediatrician with symptoms of an acute respiratory tract infection were eligible for RSV testing.

Some skin tumors can extend beyond their clinical appearance. This presents an additional challenge, especially when the affected area is the genital region, which is more difficult for both the patient and the physician to access and monitor due to its location and anatomical characteristics. The treatment of these lesions is complex, and literature postulates Mohs surgery as the best therapeutic option.

Diseases affecting bone encompass a spectrum of disorders, from prevalent conditions such as osteoporosis and Paget's disease, collectively impacting millions, to rare genetic disorders including Fibrodysplasia Ossificans Progressiva (FOP). While several classes of drugs, such as bisphosphonates, synthetic hormones, and antibodies, are utilized in the treatment of bone diseases, their efficacy is often curtailed by issues of tolerability and high incidence of adverse effects. Developing therapeutic agents for bone diseases is hampered by the fact that numerous pathways regulating bone metabolism also perform pivotal functions in other organ systems.

Unlabelled: Upper extremity deep vein thrombosis (UEDVT) is relatively rare, and much less as an initial presentation of systemic lupus erythematosus (SLE). Primary UEDVT should be considered in individuals with unilateral arm swelling where the brachial, axillary, and subclavian veins are frequently involved. SLE is a chronic autoimmune disease that predominantly affects women of childbearing age and of African descent.
