Article Synopsis
  • Miyoshi myopathy/dysferlinopathy (MMD) is a rare muscle disease linked to mutations in the DYSF gene, which also affects the brain's structure and function, although this impact hasn't been fully studied.
  • Using MRI techniques, a family study revealed significant differences in the brain of MMD patients, including an asymmetrical increase in the size of their inferior lateral ventricles and notable decreases in magnesium levels and energy metabolism in brain regions like the hippocampus.
  • Following a month of magnesium supplementation, the MMD patients showed improvements, suggesting potential benefits and calling for more research into the brain functions of MMD patients and further testing of magnesium therapy.

The incidence of small bowel schwannomas is extremely low. In the current literature, we found just a few reported small intestine schwannomas that were located in the duodenum, jejunum, or ileum. This study reports a surprising finding of a relatively large size ileal schwannoma in a patient whose preoperative magnetic resonance imaging described a tumour in the lesser pelvis probably derived from the right adnexa.

Mammography breast cancer screening programs and continuing improvements in early diagnosis of the disease have led to more frequent detection of nonpalpable breast lesions. The commonly used technique in guiding the surgical removal of these lesions is hook wire-guided localization (WGL). However, the WGL procedure has been criticized for the last years.

Introduction And Importance: Mammary myofibroblastoma (MFB) is a rare benign mesenchymal lesion. It belongs to the family of benign spindle cell tumours of the mammary stroma and may exhibit confusing variants. Some of them may mimic invasive tumours, leading to the diagnostic dilemmas, especially in core needle biopsy specimens or frozen sections.

Carbonic anhydrase IX (CA IX) is recognized as an excellent marker of hypoxia and an adverse prognostic factor in solid tumors, including breast cancer (BC). Clinical studies confirm that soluble CA IX (sCA IX), shed into body fluids, predicts the response to some therapeutics. However, CA IX is not included in clinical practice guidelines, possibly due to a lack of validated diagnostic tools.

The objective of this study was to gain our initial experience in one-step nucleic acid amplification (OSNA) for detecting sentinel lymph node (SLN) metastasis as compared to standard pathological staging in patients with breast cancer. Fifteen patients with preoperatively confirmed early breast cancer eligible for breast‑saving therapy and sentinel lymph node biopsy (SLNB) were enrolled in the study. Lymphatic mapping and SLNs detection were performed through the magnetic method.

Background: Muscle growth promoters are being developed for the treatment of disease-induced loss of muscle mass. Ligandrol and ostarine are selective androgen receptor modulators (SARMs) with a non-steroidal structure and a presumably more favorable side effect profile. In recent years, these substances with or without "post-cycle therapy" (PCT) are often misused by amateur athletes aiming to promote muscle growth.

Purpose: The most commonly used technique for guiding the surgical removal of impalpable breast lesions is wire-guided localization (WGL). Potential complications of WGL include wire migration, wire transection, patient discomfort, and pneumothorax. Recently, another possibility for preoperative localization of breast lesions trough small steel seeds was developed.

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.

Dermatofibrosarcoma protuberans (DFSP) is a rare malignant tumor of subcutaneous tissue characterized by slow infiltrative growth. The tumor occurs in patients of all ages, with the highest frequency occurring between the second and the fifth decades of age. Genetically, DFSP is characterized by a reciprocal translocation t(17;22)(q22;q13), or more often, as a supernumerary ring chromosome involving chromosomes 17 and 22.

Article Synopsis
  • Axillary lymph node dissection (ALND) has been the primary method for assessing lymph node status in breast cancer, but many patients with positive sentinel lymph nodes (SLN) do not benefit from additional ALND due to low rates of metastases in non-sentinel nodes (non-SLN).
  • A study analyzed data from 163 patients to determine which clinical and pathological factors, such as age, tumor stage, and receptor status, could predict the likelihood of non-SLN metastases in those with positive SLN.
  • The findings revealed that only the stage of the tumor was a significant predictor for metastasis in non-SLN, with a notable increase in the ratio of non-SLN positive to negative nodes in more advanced disease stages.

The authors present five cases of periosteal osteosarcoma located in the femur (4) and tibia (1) in children and young adults (1 female and 4 males) with an age range of 9 - 23 years (mean age 15 years). Radiographs in all cases showed a broad-based soft tissue mass attached to the cortex with periosteal reaction and in two of them cortical disruption with extensive medullary involvement. Follow-ups were available in four cases (range 11 - 73 months) and revealed pelvic metastasis after 15 months with ultimately rapid dissemination and death in a 9-year-old girl and metastasis to the humerus after 13 months in a 15-year-old boy.

The authors present a unique case of small cell variant of clear cell sarcoma of soft parts in a 42-year old woman. The tumor originally arose in the right flank of the soft tissues and ultimately developed both a local recurrence and multiple distant skin metastases two years and ten months thereafter. Nonspecific morphology of small blue round cell tumor was preserved at all microscopically verified sites and initially led to the spectrum of erroneous diagnoses such as an extraskeletal myxoid chondrosarcoma, Ewing sarcoma as well as malignant melanoma.
