We present a case of cerebellar tumoral multiple sclerosis in an 11-year-old girl and emphasize these two features: (1) Tumoral multiple sclerosis can occur within the posterior fossa and should be strongly considered in the differential diagnosis of mass lesions of the posterior fossa when typical white matter lesions are seen on T2-weighted images. (2) Tumoral multiple sclerosis can demonstra...

Glioblastomas, (grade 4 astrocytomas), are aggressive primary brain tumors characterized by histopathological heterogeneity. High-resolution sequencing technologies have shown that these tumors also feature significant inter-tumoral molecular heterogeneity. Molecular subtyping of these tumors has revealed several predictive and prognostic biomarkers. However, intra-tumoral heterogeneity may und...

OBJECTIVE Tumoral calcinosis is an uncommon lesion, composed of ectopic calcified tissue, most commonly seen in the large joints of the hips, knees, shoulders, and elbows. The involvement of the hand in a healthy patient is extremely rare, and therefore this condition can cause diagnostic confusion. The purpose of this report is to describe one case of idiopathic tumoral calcinosis that occurre...

INTRODUCTION Tumoral calcinosis is an uncommon disorder characterized by the development of calcified masses within the peri-articular soft tissues of large joints, but rarely occurs within the hand. CASE PRESENTATION We present the case of a 31-year-old pregnant Indian woman with a three-month history of painful swelling within the tip of her right middle finger following a superficial lacer...

Idiopathic tumoral calcinosis is an unusual benign condition characterized by the presence of calcified soft tissue masses of varying size around the joints. In this retrospective study,clinical data and radiological features of nine cases of idiopathic tumoral calcinosis are reviewed. Imaging features, particularly magnetic resonance imaging findings are detailed.

A morphometric analysis of tumoral Langerhans cells and activated macrophages was conducted using canine cutaneous tumors (65 cases of canine cutaneous histiocytoma and 7 cases of pyogranuloma). The histiocytic origin of the tumor cells was confirmed using immunohistochemistry. The parameters of the morphometric analysis included cellular and nuclear size and shape and the nuclear:cytoplasmic r...

We report a case of a tumoral calcinosis mimicking the appearance of recurrent osteosarcoma of the left femur and tibia in a 29-year-old woman with a history of osteosarcoma and chronic renal failure. Both processes can appear radiographically and histologically similar. Due to loosening of the orthopedic hardware, our patient underwent surgical revision and biopsy. We review the imaging appear...

INTRODUCTION Tumoral calcinosis is a rare syndrome characterized by massive subcutaneous soft tissues deposits of calcium phosphate near the large joints. The condition has been reported in patients ranging from age 5 months to 83 years (Bostrom et al, 1981; Aprin et al 1986), it usually becomes manifest in the second decade of life (Aprin et al, 1986). Men and non-whites are affected more comm...
