An infant boy presented at birth with a large mass protruding from the left orbit that significantly displaced the left globe laterally and inferiorly . Biopsy of the mass was performed the next day, yielding the diagnosis of infantile myofibromatosis. Therapy was considered but the parents opted for no treatment, although they agreed to yearly CT follow-up examinations. The CT study at the tim...

Infantile myofibromatosis (IM) is a rare benign tumor in children. It was first described as congenital fibrosarcoma. Later, sporadic cases were discussed, and in 1981, 61 cases were examined and named as IM. Three different forms were described: solitary, multicentric and visceral IM.1 Three quarters of soft tissue tumours in children and adolescents are benign, 95 % of them are fibromatosis, ...

Spectrum of Fibroblastic and Myofibroblastic Tumors When one considers soft tissue tumors in pediatrics, tumors of vascular (29%), neurogenic (15%), and myogenic (striated muscle, 14%) origin occur more often than fibroblastic-myofibroblastic tumors (12%). The spectrum of fibroblastic/myofibroblastic tumors is quite divergent from both clinical and histopathologic viewpoints (Table 1). These tu...

Infantile myofibromatosis (IMF) is a rare group of reactive lesions. Their clinical, radiological, and pathological features may be confused with those of malignancy. The lung and mediastinum are the most common site of IMF in all pediatric age groups [1–4]. We present a case of a 9-year-old boy presenting with a history of recurrent abdominal pain and chronic diarrhea since the age of one. He ...

We introduce a new class of games, congestion games with failures (CGFs), which extends the class of congestion games to allow for facility failures. In a basic CGF (BCGF) agents share a common set of facilities (service providers), where each service provider (SP) may fail with some known probability. For reliability reasons, an agent may choose a subset of the SPs in order to try and perform ...

The amino (AA) profile of eight feedstuffs (two samples of fishmeal, soybean meal [SBM], formaldehyde-treated SBM, sopralin, cotton-seed meal [CSM], rapeseed meal [RSM], corn distillers grains [CDG], and corn gluten feed [CGF]) was determined before and after ruminal incubation for 8 and 12 h in three lactating Friesian cows using nylon bags. The profile of AA disappearing during intestinal pas...

Desmoid fibromatoses are benign, slow growing fibroblastic neoplasms, arising from musculoaponeurotic stromal elements. Desmoids are characterized by local invasion, with a high rate of local recurrence and a tendency to destroy adjacent structures and organs. Desmoid fibromatoses are rare in children, and though they may occur in the head and neck region, are extremely rare in the paranasal si...
