Fibromatoses are benign tumors that can occur anywhere in the body. They are locally aggressive and tend to recur; they also cause considerable morbidity, particularly when they arise in the head and neck. Fibromatosis in the submandibular region is rare. Here, we present a case of fibromatosis of the submandibular region in a 42-year-old female who presented with a right submandibular mass. Th...

Mesenteric fibromatosis is a rare benign disease characterized by proliferating fibrous tissue in the bowel mesentery. We report a case of aggressive mesenteric fibromatosis with ureteral stenosis arising in a 46-year-old woman who suffered from intermittent right abdominal pain. Computed tomography revealed a right retroperitoneal mass with right ureteral stenosis at the level of the right com...

Fibrous tissue proliferations express a wide spectrum of histologic and morphologic variation in both infants and adults. This ranges from hypertrophic scar formation at one end to malignant fibrosarcoma at the other end of the spectrum. Aggressive fibromatosis is an intermediate tumor which is in proximity to fibrosarcomas. These are locally invasive and often recur after excision, but do not ...

Gingival fibromatosis is a progressive gingival enlargement caused by an over growth of the collagenous element of the gingival fibrous connective tissue. Pharmacologically induced, hereditary (familial) and idiopathic forms of gingival fibromatosis are recognized. This paper reports a case of idiopathic gingival fibromatosis in a 13 year old boy involving the right maxillary and mandibular arc...

Mesenteric fibromatosis is a rare benign nonmetastatic neoplasm that appears as a sporadic lesion or occurs in patients with familial polyposis, while chylous ascites associated with aggressive mesenteric fibromatosis during pregnancy has never been reported thus far. Here we present the case of a 28-year old pregnant woman, in whom an aggressive mesenteric fibromatosis with chylous ascites was...

Desmoid-type fibromatosis is a rare mesenchymal neoplasm with local aggressiveness. The incidence of desmoid-type fibromatosis is 2-5/million/year with intra-abdominal fibromatosis, such as that which is reported in this clinical case, occurring only in 12-18% of cases. After having analyzed the pathogenetic hypotheses of desmoid-type fibromatosis, the authors point out that the diagnosis of th...

Fibromatosis is a benign tumor that rarely affects the breast and is an unusual site for its occurrence. Whilst the definite etiology of breast fibromatosis is unclear, it may present itself following surgical trauma or silicone implant. Wide local excision with adequate safety margins is considered the standard of care. We review three cases of breast fibromatosis who were presented to and ope...

Gingival fibromatosis is usually seen as an isolated finding or occasionally in association with other features as part of a syndrome. The combination of gingival enlargement, hypertrichosis, epilepsy and mental retardation is also a commonly reported syndrome that features gingival fibromatosis. The following report is about a mentally retarded patient who has shown no sign of hypertrichosis, ...

Background: Aggressive fibromatosis is a rare benign tumor with no potential for metastasis; however, its aggressive nature causes treatment failure and episodes of recurrence. There is no report from Iran about the treatment of this tumor, and all published articles are single-case reports, therefore in this study, we report our experience from two of...

Mesentery fibromatosis, also called abdominal desmoid, is a rare clinical entity. It is part of the clinical-pathologic spectrum of so-called deep fibromatoses. The deep fibromatoses encompass a group of benign fibroproliferative processes that are locally aggressive; they may infiltrate the adjacent organs or recur, but do not create distant metastatic lesions. The small bowel mesentery is the...
