Osseous metaplasia is a phenomenon which is described in a variety of tissue types with respect to both neoplastic and non-neoplastic conditions. In the gastrointestinal tract, osseous metaplasia (heterotopic bone formation) is rarely detected. Most of the reported cases were associated with malignant lesions. Here, we are reporting a rare case of a juvenile rectal polyp in a 14 years male, whi...

Synovitis, acne, pustulosis, hyperostosis, and osteitis (SAPHO) syndrome, a rare disorder with spectrum of manifestations overlapping osseous cutaneous symptoms, shares pathogenesis various autoimmune diseases. SARS-CoV-2 has been previously linked to diseases like Guillain-Barré syndrome (GBS), multi-inflammatory in children (MIS-C), or rheumatoid arthritis, but there is no existing work showi...

Tarsal tunnel syndrome (TTS) is defined as the entrapment of the posterior tibial nerve in the tarsal tunnel of the ankle. The etiologies of tarsal tunnel syndrome are mainly the presence of a ganglion, osseous prominence with tarsal bone coalition, trauma, varicose veins, neurinoma, hypertrophy of the flexor retinaculum, or systemic disease (rheumatoid arthritis, ankylosing spondylitis). Howev...

Secondary osseous involvement in lymphoma is more common compared to primary bone lymphoma. The finding of osseous lesion can be incidentally discovered during the course of the disease. However, osseous metastases are infrequently silent. Detection of osseous metastases is crucial for accurate staging and optimal treatment planning of lymphoma. The aim of imaging is to identify the presence an...

We compared the ability to diagnose skeletal metastasis between serum prostate specific antigen (PSA), C-terminal propeptide of blood type I procollagen (PICP), and urine type I collagen-crosslinked N telopeptide (NTx) in prostate cancer patients. In sixty-nine patients with prostate cancer, bone scintigraphy was performed, and serum PSA and PICP and urine NTx were measured. The median level of...

The neurofibroma (NF) is a benign tumor of the peripheral nerve sheath that rarely affects the head and neck. However, among neural lesions, this is the one that most frequently affects this region. The NF can be intra or extra-osseous, alone or multiple (associated with type I neurofibromatosis). The most common extra-osseous mouth NF locations are tongue, oral mucosa and lips. In the literatu...
