Abstract
BACKGROUND Collagenous fibroma or desmoplastic fibroblastoma is a rare benign fibrous tissue tumor. It usually presents as a painless, slowly growing mass. Collagenous fibroma arises ordinarily inside the subcutaneous tissues or skeletal muscles. Histopathologically, the tumor consists of scattered stellate and spindle cells in a hypovascular collagenous stroma without atypia or infiltration. The oral cavity is a very uncommon site for desmoplastic fibroblastoma. Only 15 published articles in the literature reported the intraoral location. We present a case of collagenous fibroma with a bilateral distribution on the hard palate. This is the second case of bilateral collagenous fibroma after a previously reported one in literature; however, our case was larger, occupying almost the whole palate. We discuss the management of this rare tumor and how we can reach definite diagnosis. CASE PRESENTATION A 37-year-old Caucasian female patient had a huge bilateral firm palatal mass that caused breathing problems. There was no history of trauma and the patient had no relevant medical history Total surgical excision under general anesthesia was carried out and histopathological examination suggested a benign mesenchymal tumor. Immunohistochemistry was necessary to confirm the tumor origin and to exclude aggressive fibromatosis. A diagnosis of bilateral collagenous fibroma was reached. Six months after surgery, there was no recurring lesion and the patient's health was good. CONCLUSIONS Collagenous fibroma is a benign fibrous tissue tumor of unknown cause that is treated with simple excision. The prognosis is good with no recurrence. Reaching an accurate diagnosis is mandatory to avoid aggressive treatment since collagenous fibroma may be misdiagnosed as aggressive fibromatosis in case of massive size. Clinicians and pathologists should be aware of this unusual tumor for conservative management without side effects.

[PMID: 33829348 PMCID: PMC8026786 DOI: 10.1186/s40792-021-01171-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/08/2021] [Accepted: 03/29/2021] [Indexed: 11/16/2022] Open
Abstract
Background Desmoplastic fibroblastoma is an uncommon, benign, fibrous tumor exhibiting infiltrative growth. Most of these tumors are small, slow-growing, and develop as subcutaneous lesions in the extremities. Cases of desmoplastic fibroblastoma in the chest wall are quite rare, and the preoperative diagnosis of such cases remains challenging as these tumors can mimic the characteristics of desmoid-type fibromatosis, which often occurs in the chest wall. We aimed to describe a rare case of desmoplastic fibroblastoma exhibiting rapid growth in the chest wall of a patient that was successfully treated with marginal excision only by diagnostic imaging before surgery. Case presentation A 79-year-old man was admitted to our hospital after experiencing right shoulder pain lasting for a few months. A 4 × 4 × 2 cm mass was incidentally detected at the right second rib two years prior. Chest computed tomography revealed a well-defined homogeneous mass with a muscle-like density along the right lateral chest wall, the size of which had increased to 12 × 10 × 4.5 cm in two years. Dynamic contrast-enhanced computed tomography revealed abundant vascularity at the periphery of the tumor. Magnetic resonance imaging revealed iso-intensity to muscle on T1-weighted images, slightly high intensity on T2-weighted images, and rim-like contrast enhancement at the periphery of the tumor, with uniform thickness on gadolinium-enhanced T1-weighted images with fat suppression. Rim-like contrast enhancement is an imaging feature that can distinguish cases of desmoplastic fibroblastoma from desmoid-type fibromatosis. We diagnosed the tumor as desmoplastic fibroblastoma by diagnostic imaging without tissue biopsy. Marginal excision with videoscopic assistance was performed through a small incision. The pathological diagnosis was desmoplastic fibroblastoma. The patient’s postoperative course was uneventful, and his shoulder pain was relieved after the surgery. Conclusions Desmoplastic fibroblastoma in the chest wall is extremely rare, but should be considered in the differential diagnosis when desmoid-type fibromatosis is clinically suspected. Gadolinium-enhanced magnetic resonance imaging is helpful in confirming the differential diagnosis.

Abstract
BACKGROUND The term "symmetrical palatal fibromatosis" was recently suggested to designate bilateral palatal lesions presenting as typically broad, "mirror" images on the posterior lateral region of the hard palate. PURPOSE We report an additional case of this as-yet poorly understood oral lesion in a 67-year-old male patient, with emphasis on differential diagnoses and immunohistochemical characterization. CASE REPORT The histopathological examination demonstrated a hypocellular, fibrous connective tissue with prominent thick collagen bundles and few blood vessels. Scattered large, stellate, and sometimes binucleated fibroblasts were found. Immunohistochemistry was positive for vimentin and negative for smooth muscle actin, S-100, desmin, HHF-35, AE1-AE3, Factor XIIIa, CD68, and FOSL1. This is the second study to show the immunohistochemical profile, with emphasis in FOSL1, of an additional case of symmetrical palatal fibromatosis. CONCLUSIONS We encourage further reports about this entity, especially in relation to immunohistochemical and molecular features, so far poorly described, but very important for better recognition of this entity. Key words:Palate, symmetrical palatal fibromatosis, desmoplastic fibroblastoma, immunohistochemistry.

Abstract
OBJECTIVE To present five cases of symmetrical palatal fibromatosis (SPF), a lesion reported very rarely in the English language literature, under more than a dozen different names, and to recommend the most appropriate name. METHODS Five SPF cases are characterized with a literature review. RESULTS Three females and two males, aged 20-39 years, presented with bilateral, symmetrical, asymptomatic, sessile, moderately firm, or soft (n = 2) masses of the lateral posterior hard palate; two were isolated to the tuberosities. All masses were normal in color, with smooth, non-ulcerated surfaces and occasional surface nodularity. Underlying bone was radiographically normal, and adjacent teeth were asymptomatic. All masses originated from supra-periosteal tissues over palatal bone, only secondarily extending to gingivae and/or crestal tuberosity. Cases were present between 4 months and 15 years, with no familial or environmental etiologies identified. Histopathologically, masses were comprised of dense, avascular fibrous tissue with scattered thick bands of collagen. Surface epithelium showed occasional long, thin, sometimes pointed rete processes, and subepithelial stroma contained scattered large, angular fibroblasts. Conservative surgical excision appeared curative in all cases. CONCLUSIONS The present investigators propose SPF as the most accurate name for this rare entity.

Abstract
Desmoplastic fibroblastoma is a rare fibrous tumor that usually presents as a painless, slow-growing mass in the subcutaneous tissues and skeletal muscles. It has a wide anatomic distribution, with the most common involvement being the arm and shoulder. Here, we report a case of a tiny painful desmoplastic fibroblastoma arising on the scalp. According to a microscopic examination, this tumor was composed of spindle-shaped fibroblasts in the dense collagenous stroma. On immunohistochemical staining, tumor cells were positive for vimentin and negative for smooth muscle actin, CD34, and S100. Our case is unique in that desmoplastic fibroblastoma developed on the scalp and there was presence of pain despite its small size.

Abstract
Desmoplastic fibroblastoma (DF) is a rare benign soft tissue with spindle-to-stellate-shaped fibroblasts and myofibroblasts embedded in a prominent collagenous background. DF, mainly affecting subcutaneous and muscle tissue, very rarely occurs in the oral cavity. Hitherto, only one case of DF on the tongue has been reported. Here, we report another case. A 66-year-old woman was referred to our hospital with a mass formation in the tongue. On examination, a well-circumscribed, elastic, soft tumour with normal surface mucosa, measuring 13×12 mm, was observed on the left dorsal surface of her tongue. MRI and ultrasonography confirmed the mass, and a benign tongue tumour was suspected. The tumour was surgically resected under general anaesthesia 1 month later, leading to the histopathological diagnosis of DF. She experienced an uneventful clinical recovery after surgery, with no recurrence noted for more than 1 year postoperatively.

Abstract
Collagenous fibroma, also known as desmoplastic fibroblastoma, is a rare benign slow growing tumor particularly uncommon in the oral cavity. The aim of this study was to analyze the clinical and histopathological features of an oral collagenous fibroma as well as to compare this data with those reported in an English-literature review. The thirteenth case of collagenous fibroma in the oral cavity and the first to present clinically as a bilateral mass was described. A 48-years-old female patient was referred to a School of Dentistry, complaining about an asymptomatic swelling on the hard palate, lasting around ten years. The intraoral examination revealed two well-defined mass, bilaterally in the hard palate. An excisional biopsy was performed. Microscopically, the connective tissue consisted of dense collagen bundles in which were seen scarcely distributed spindle-shaped to stellate fibroblastic cells. Blood vessels were few, as well as inflammatory cells. Immunohistochemical staining was positive for vimentin, α-smooth muscle actin and factor XIIIa and negative for S-100, CD68, CD34, HHF35, desmin and AE1/AE3. The patient remains disease-free 24 months after excision. In conclusion, oral collagenous fibroma should be included in the differential diagnosis of bilateral sessile nodules in the oral cavity.

Abstract
AIM The aim of the present study was to analyze the prevalence of benign tumors of the orofacial region at a tertiary referral center in the south-western region of Saudi Arabia. METHODS Cases from 2009 to 2014 were retrieved from October 2014 to June 2015 from the archives of the histopathology department of the center. Demographic and clinical details of the patients were recorded. RESULTS Of the 714 oral and maxillofacial biopsy specimens, 78 (10.9%) were benign tumors. The mean age and range were 34.6±19.8 and 3-85 year, respectively. Sex distribution was equal. Most tumors were mesenchymal (34.6%), followed by epithelial (26.9%), odontogenic (20.5%), and salivary gland tumors (17.9%). Squamous cell papilloma (20.5%) was the most common, followed by pleomorphic adenoma (15.4%) and fibrous tumors (15.4%). CONCLUSIONS The low prevalence of benign orofacial tumors found in this study indicates a lack of awareness of the importance of taking biopsy for such lesions. The information reported here emphasizes the need for biopsy investigation for all oral lesions to ascertain appropriate diagnosis.

Abstract
UNLABELLED Desmoplastic fibroblastoma is benign soft tissue tumor, with fibroblastic or myofibroblastic origin, that rarely occurs in oral cavity. We reported the case of a 56-year-old man who presented a tumor in the left mandibular alveolar ridge, with slow and asymptomatic growth, with no osseous involvement. The tumor was sessile with lobulated surface, covered by healthy mucosa with erythematous areas. The lesion was excised and specimens sent to histopathology and immunohistochemistry. Histopathological exam showed a non-encapsulated fibroblastic proliferation, characterized by myofibroblasts, spindle and stellate fibroblasts with large or oval nuclei and bi or tri nucleation, immersed in an abundant hypocellular dense collagen stroma. Tumor cells were positive for vimentin, HHF35, α-smooth muscle actin and factor XIIIa. The diagnosis of desmoplastic fibroblastoma was based in the clinical history of absence of trauma related to the growth in the alveolar ridge, associated with macroscopic, microscopic and immunohistochemical features. The patient is free-diseases by eight months. KEY WORDS Collagenous fibroma, desmoplastic fibroblastoma, neoplasm of connective and soft tissue.

Abstract
The fibrous epulis, a common tumor-like lesion of the gingiva, appears in the interdental papilla as a result of local irritation. Lesions are asymptomatic and have a variable growth rate. A 75-year-old woman was referred for the evaluation of a large painless gingival mass. It had started 10 years back and has been increasing in size the last year. No bone involvement was noted. The tumor was totally removed by excision with surgical scalpel under local anesthesia without teeth extraction. The microscopic findings were suggestive of a fibrous epulis. Differential diagnosis, clinical considerations and factors to prevent recurrence are discussed.

Abstract
Desmoplastic fibroblastomas (DFs) are rare fibrous soft tissue tumours that usually arise in subcutaneous tissue or skeletal muscle in a variety of anatomical sites. These lesions most frequently present as painless, slow-growing mobile masses. A case of DF is described in a 47-year-old man who presented with a painless right parotid mass of 2 months duration. At surgery, the lesion was attached to the tail of the right parotid gland. Histopathological examination demonstrated a fibrous lesion comprising spindled and stellate shaped fibroblasts with focal myxoid stromal change. The features were consistent with a DF. This report documents a rare parotid lesion which may mimic other more common parotid gland neoplasms.
