ABSTRACT
AIM: In this study we used a new technology for localization of non-palpable breast tumors using a small steel marker in conjunction of sentinel nodes (SLNs) detection through injection of SPIO nanoparticles; both detected through a magnetic probe. Materials & methods: Ten patients with biopsy-proven nonpalpable invasive breast carcinoma or premalignant lesions eligible for SLNs biopsy were enrolled in this study. RESULTS: All tumors were removed with safe surgical margins. The mean nodal detection rate was 3.4 nodes per patient. No interferences in magnetic probe measurements due to the presence of both markers in the same breast were observed. CONCLUSION: Simultaneous use of the magnetic method in localization of impalpable breast tumors and SNs detection makes breast surgery convenient.

Myositis ossificans (MO) is characterized by abnormal heterotopic ossification formation, typically involving muscles, tendons, ligaments, fascia, and aponeurosis. It can be categorized into nonhereditary and hereditary types, with the latter being a distinct entity with a separate pathophysiology and treatment approach. The pathophysiology of MO formation remains to be fully elucidated. MO is most commonly observed in muscle tissue as a solitary lesion. The disease has been reported to occur in all ages, including the very young and in atypical locations, including hands, feet, ribs, head and neck. The present case report describes an unusual pseudomalignant form of MO in the breast. The authors discuss the clinical and morphological characteristics of the tumor and its treatment options.
ABSTRACT
A 62-year-old man presented with diabetes insipidus, pulmonary fibrosis, right atrial tumor and bilateral knee osteoarthritis with cystic lesions of distal femur and proximal tibia. Scintigraphy and histological examination of right femur bone biopsy revealed changes characterized for Paget's disease. Re-evaluation of the computer tomography (CT) scans and histological samples revealed diffuse infiltrates of foamy histiocytes in the bone marrow what was consistent with Erdheim-Chester disease. Positron emission tomography/computed tomography (PET/CT) was performed to access the activity and extent of disease.
