Gardner fibroma
Gardner fibromas or Gardner associated fibromas are benign fibrous plaque-like soft tissue masses formed by a haphazard arrangement of collagen fibres usually associated with familial adenomatous polyposis.
Terminology
The term 'desmoid precursor lesion' is now discouraged 1.

Article
Desmoplastic fibroma
Desmoplastic fibromas are extremely rare bone tumours that do not metastasise but may be locally aggressive. They are considered to be a bony counterpart of soft tissue desmoid tumours and are histologically identical.
Epidemiology
Desmoplastic fibroma of bone is rare and mostly found in youn...
Article
Ovarian fibroma
Ovarian fibromas are benign ovarian tumours of sex cord/stromal origin. Although fibromas account for ~4% of all ovarian neoplasms, they are the most common sex cord ovarian tumours.
Epidemiology
Fibromas occur at all ages but are most frequently seen in middle-aged women.
Associations
They ...
Article
Odontogenic fibroma
Odontogenic fibromas are benign mesenchymal odontogenic tumours with varying amounts of fibrous connective tissue.
Epidemiology
Odontogenic fibromas are rare tumours and are more common in women. Central odontogenic fibromas occur in a wide age range and peripheral odontomas have a peak betwee...
Article
Cardiac fibroma
Cardiac fibromas, also known as cardiac fibromatosis, are benign congenital cardiac tumours that usually manifest in children.
Epidemiology
Cardiac fibromas are tumours that primarily affect children (most cases are detected in infants or in utero) with a ratio of 4:1 compared with adults 5. ...
Article
Ossifying fibroma
Ossifying fibromas are benign bone lesions that should be differentiated from non-ossifying fibromas and fibrous dysplasia. Osteofibrous dysplasia is considered as a separate pathological entity in view of its different presentation and treatment, although histopathologically similar to ossifyin...
Article
Chondromyxoid fibroma
Chondromyxoid fibromas (CMF) are extremely rare, benign cartilaginous neoplasms that account for <1% of all bone tumours 1.
CMF accounts for one of the 'C's in the popular mnemonic for lucent bone lesions FEGNOMASHIC.
Epidemiology
As with all rare lesions, reported epidemiology varies:
age:...
Article
Ameloblastic fibroma
Ameloblastic fibromas appear as unilocular lucent mandibular lesions, most frequently in the posterior mandible, and are usually associated with impacted teeth, centred on the unerupted crown. They, therefore, appear very similar to unilocular ameloblastomas. They are composed of enamel and embr...
Article
Calcifying aponeurotic fibroma
Calcifying aponeurotic fibromas, also known as juvenile aponeurotic fibromas or just aponeurotic fibromas are superficial benign potentially recurrent fibroblastic soft tissue tumours usually seen in the palms and soles of children and adolescents 1,2.
Epidemiology
Calcifying aponeurotic fibr...
Article
Nuchal type fibroma
Nuchal-type fibromas or nuchal fibromas are rare benign fibrous tumours arising from the connective tissues of the neck.
Terminology
The term 'collagenosis nuchae' is now discouraged 1.
Epidemiology
Nuchal-type fibromas are rare tumours and are mainly found in men in their 30s and 40s 1.
As...
Article
Tendon sheath fibroma
Tendon sheath fibromas are rare proliferative lesions with common imaging features of tenosynovial giant cell tumours.
Epidemiology
They are found in adults typically between the age of 20 and 50 with a 3:1 male predominance 2.
Pathology
Tendon sheath fibromas are lobulated, round-to-oval, e...
Article
Non-ossifying fibroma
Non-ossifying fibromas (NOF) are benign and generally self-limiting osteoclastic giant cell-rich bone tumours typically found in the metaphyses of long bones. They are classified as osteoclastic giant cell-rich bone tumours 1,2.
NOFs account for the 'N' in the popular mnemonic for lucent bone l...
Article
Cemento-ossifying fibroma
Cemento-ossifying fibroma (COF) are rare, benign neoplasms that usually arise from the mandible or maxilla. They most often arise from the tooth bearing areas of these bones.
Terminology
In the 2005 WHO histological classification of odontogenic tumours, this tumour is referred to as "ossifyin...
Article
Osteofibrous dysplasia
Osteofibrous dysplasia is a benign fibro-osseous cortical lesion that occurs almost exclusively in the tibia and fibula. It is most commonly seen in the mid-diaphysis of the tibia. Some consider it synonymous with ossifying fibroma because of histological similarities, but it is generally consid...
Article
Desmoplastic fibroblastoma
Desmoplastic fibroblastoma also known as collagenous fibromas are rare benign fibroblastic soft tissue tumours with an abundant collagenous or myxocollagenous stroma seen in adults1-3.
Epidemiology
Desmoplastic fibroblastomas are rare and usually occur in the adult population with a median age...
Article
Solitary fibrous tumour of the thorax
Solitary fibrous tumours of the thorax are rare pleural-based tumours that account for <5% of all primary pleural tumours 16. While their behaviour is variable, they are typically indolent, benign-behaving tumours. Locally aggressive features with malignant transformation, into undifferentiated ...
Article
Inclusion body fibromatosis
Inclusion body fibromatosis is a superficial benign myofibroblastic tumour characterised by eosinophilic intracytoplasmatic inclusions. These tumours are also known under the terms infantile digital fibroma or fibromatosis, recurring digital fibroma of childhood, recurring digital fibrous tumour...
Article
Osteoblastoma
Osteoblastomas are rare bone-forming tumours that may be locally aggressive. Compared to their histological relative, the osteoid osteoma, they are larger (>2 cm) and more frequently affect the axial skeleton 1.
Osteoblastoma accounts for the 'O' in the popular mnemonic for lucent bone lesions ...
Article
Uterine leiomyoma
Uterine leiomyomas, also known as uterine fibroids, are benign tumours of myometrial origin and are the most common solid benign uterine neoplasms. Commonly an incidental finding on imaging, they rarely cause a diagnostic dilemma.
Epidemiology
They are clinically apparent in ~25% of women of r...
Article
Benign fibrous histiocytoma of bone
Benign fibrous histiocytoma of bone is a term that has been used for a type of bone lesion considered histologically identical to non-ossifying fibroma but was distinguished on the basis that it was described in the adult population 1,2. The lesion needs to be differentiated from cutaneous or de...
