Sixty six-year-old woman status post ileocecal resection for well-differentiated neuroendocrine tumor in the terminal ileum 7 years ago, who is on octreotide therapy for liver metastases. Ga DOTATATE PET/CT showed soft tissue masses with mildly increased radiotracer uptake in the bilateral subscapular/infrascapular regions. In retrospective image review, these soft tissue masses were first noted 7 years prior and have gradually increased in size over the years. Read More

Chest wall neoplasms mainly include malignancies, metastatic in particular. Differential diagnosis should include clinical data; tumor location, extent, delineation; the degree of homogeneity; the presence of calcifications; the nature of bone destruction and the degree of vascularization. The aim of the paper is to present both the benefits and limitations of ultrasound for the diagnosis of chest wall neoplasms. Read More

In recent years, the number of cancer patients who undergo endoscopic surgery has been increasing, and port-site recurrence is becoming a more common complication. A 66-year-old woman underwent thoracoscopic left lower lobectomy with lymph node dissection for pT1aN0M0 adenocarcinoma of the lung. Six years after surgery, CT revealed a subscapular tumor measuring 3 cm at the site of the surgical port wound. Read More

Radioiodine uptake in the thyroid tissue, metastasis of differentiated thyroid cancer (DTC), and in other tissues, depends on the expression of sodium-iodide symporter (NIS). Vascular permeability, effusions, inflammation, and other mechanisms may also play a role in the accumulation of radioactive iodine. A 63-year-old woman underwent radioiodine therapy, as well as a post-therapy whole-body scan, as she was suspected of having lung metastasis from thyroid carcinoma. Read More

Lipomatous lesions are common musculoskeletal lesions that can arise within the soft tissues, bone, neurovascular structures, and synovium. The majority of these lesions are benign, and many of the benign lesions can be diagnosed by radiologic evaluation. However, radiologic differences between benign and malignant lipomatous lesions may be subtle and pathologic correlation is often needed. Read More

Elastofibroma is a rare tumour that occurs in the subscapular space, and it typically presents in middle-aged and older individuals. The aetiology of elastofibroma remains unknown. Recent, sporadic reports have shown, immunohistologically, that fibroblasts in elastofibroma may produce abnormal elastic and collagen fibres through the action of transforming growth factor-beta (TGF-β), a factor that promotes fibroblast proliferation.

Elastofibroma dorsi (ED) is considered a member of a heterogeneous group of benign fibrous (fibroblastic or myofibroblastic) soft-tissue tumors, frequently localized in the periscapular region in middle aged or older individuals. However, the pathogenesis of ED is still unclear and many authors believe that ED results from a reactive hyperproliferation of fibroblastic tissue, while others suggest that it may be a consequence of a mechanical friction. In our study, we examined 11 cases of ED using histochemical and immunohistochemical methods, in order to extend the knowledge about extracellular matrix composition and histopathogenesis of ED.

From 1990 to 2013 at our center, 115 patients underwent elestofibroma surgical removal, including 2 bilateral and one relapsed. For all the patients ultrasound preoperative examination was requested, sometimes with a diagnosis of lipoma or fibrolipoma because of the rarity of this type of lesion and therefore the lack of experience of the radiologists.
