Orbital pseudolymphomas are uncommon benign tumors composed of reactive lymphocytes. The typical clinical presentation is painless onset of ptosis, proptosis, diplopia, or eyelid swelling. Virtually any adnexal structure can be affected, but lacrimal gland, orbital soft tissue, or extraocular muscles are the usual sites of involvement. Historically, treatment has been with oral corticosteroids ...

Human sparganosis is a foodborne zoonosis endemic in Asia. We report a series of 9 histologically confirmed human sparganosis cases in Hong Kong, China. All parasites were retrospectively identified as Spirometra erinaceieuropaei. Skin and soft tissue swelling was the most common symptom, followed by central nervous system lesions.

Acute urinary retention secondary to vasculitic penile swelling in children is extremely rare. Henoch-Schönlein purpura is a self-limiting IgA-mediated cutaneous vasculitis, which can cause soft tissue edema. Acute urinary retention requires urgent intervention to prevent obstructive uropathy. Suprapubic catheterization provides an effective management strategy in the emergency setting.

Six patients, aged between 3 and 51 years, with tuberculosis of the upper cervical spine were studied. Prominent features of the disease included pain and stiffness, paralysis, swelling of the retropharyngeal soft tissue, osteolytic erosions, and atlanto-axial subluxation. Cure was obtained with antibiotics, transoral decompression and C1-2 fusion.

Haemangioma is a common benign soft tissue tumour. Intramuscular haemangiomas may present as a perceived sporting injury. Magnetic resonance imaging is the investigation of choice. Intramuscular haemangioma should be considered in the differential diagnosis of unexplained pain and swelling in a muscle.

Nasolabial cyst is a rare non-odontogenic, soft-tissue, developmental cyst occurring inferior to the nasal alar region. The patient usually presents with a slowly enlarging asymptomatic swelling, typically without radiographic abnormalities. This paper documents the presentation and management of a 46-year-old woman with a nasolabial cyst. The histopathologic features, differential diagnosis, t...

Background Pachydermodactyly is a rare benign superficial fibromatosis, aetiology unknown, characterized by asymmetric painless swelling of the proximal interphalangeal (PIF) joints of the hands, most frequently in adolescent males. Radiographs and MRI show only soft tissue thickening. Histological exam reveals epidermic hiperplasia, collagen fibers and fibroblast proliferation and increased mu...

objective: the aim of this study is to evaluate the effect of tissue composition on dose distribution in electron beam radiotherapy. methods : a siemens primus linear accelerator and a phantom were simulated using mcnpx monte carlo code. in a homogeneous cylindrical phantom, six types of soft tissue and three types of tissue-equivalent materials were investigated. the tissues included muscle (s...

in this paper an automatic examination robot was developed to improve the process of cancer detection, tumor localization and geometrical shape diagnosis. a uniformly distributed compressive load was applied to the top tissue surface and the resultant mechanical stress was measured that was employed for the tumor diagnosis task. the experimental examinations were performed on the soft tissue of...
