Prepubertal vulvar tumors are rare and may represent mesenchymal tumors, hamartomas, or vascular malformations. Their presentation may be similar but they do not have the same prognosis and management. We report 2 cases of labium majus hypertrophy corresponding to prepubertal vulvar fibromas.

A 35-year-old woman was referred to the Department of Oral Medicine and Orofacial Surgery after several recurrences of an ossifying fibroma (OF) that affected the free and attached gingiva of the maxillary right central incisor. Surgery was performed with a complete excision of the lesion together with the surrounding healthy tissue up to the bone. To guide the healing of the anterior esthetic framework and the excised tissues, a porcine collagen matrix as an alternative to connective tissue graft was used...

Cowden syndrome is an autosomal dominant disorder with a predisposition to multiple benign and malignant tumors with unique oral manifestations. We present a case of Cowden syndrome in a patient diagnosed with breast cancer, traumatic fibromas, bronchial asthma, and multiple papillomatous fibromatosis of the oral cavity. Close association between oral papillomatosis associated with Cowden syndrome and PTEN gene mutation may increase the risk for malignant transformation. Therefore, patients of Cowden syndrome should be monitored carefully for all kinds of cancers...

BACKGROUND: Retrospective studies to assess the distribution of oral diseases (ODs) are helpful in estimating the prevalence of oral diagnoses in the population, and thus help in preventive and curative services. Prevalence and frequency data for ODs are available from many countries, but information from Chile is scarce. MATERIAL AND METHODS: This study investigated the frequency of OD in a Chilean population. For this, we included all patients treated at the University of Talca (UTALCA, Chile) between 2001 and 2014...

There are several treatment options for hyperplastic gingival lesions. Among these, diode lasers have the advantages of less bleeding, which is an important characteristic in mucosal lesions, a shorter procedure time, better healing, and less complications. We present the case of a 48-year-old male patient with a history of cerebral palsy and a presumptive diagnosis of traumatic fibroma. The entire lesion was removed in one session with no complications. No recurrence was observed at 3 months follow up. This procedure can be considered a good modality especially for physically challenged patients...

Inactivating mutations that lead to loss of heterozygosity within the HRPT2/Cdc73 gene are directly linked to the development of primary hyperparathyroidism, parathyroid adenomas, and ossifying fibromas of the jaw (HPT-JT). The protein product of the Cdc73 gene, parafibromin, is a core member of the polymerase-associated factors (PAF) complex, which coordinates epigenetic modifiers and transcriptional machinery to control gene expression. We conditionally deleted Cdc73 within mesenchymal progenitors or within mature osteoblasts and osteocytes to determine the consequences of parafibromin loss within the mesenchymal lineage...

Desmoplastic fibroma (DF) of bone is considered a benign but locally aggressive tumor of fibroblastic origin. DF is rare, representing less than 1% of all bone tumors. Approximately 84% of patients are younger than 30 years. DF has a slow but aggressive growth potential and can recur locally when it has not been completely excised. Complete resection is the treatment of choice to decrease recurrence and morbidity. Mandibular reconstruction is mandatory in pediatric patients to ensure correct craniofacial development...

BACKGROUND: Head and neck ossifying fibroma (OF) is a rare, benign, locally aggressive, fibro-osseous tumor. The mandible is the most common site of involvement, followed by the maxilla, and, less frequently, the sinonasal cavities, orbit, skull base, and calvarium. In this study, we aimed to expand our understanding of this entity by presenting a case series of OF that involved the maxilla and sinonasal tract. METHODS: A multicenter retrospective review was performed on all the patients with a diagnosis of OF from 2004 to 2013...

Gingival growths are one of the most frequently encountered lesions in the oral cavity. A plethora of lesions can be seen having similar clinical presentation, making diagnosis a dilemma. Peripheral odontogenic tumors are rare neoplasms to occur on gingiva, the most common among them being the peripheral odontogenic fibroma (POdF). The POdF is a benign, slow-growing, exophytic lesion. Although considered to have a recurrence potential after excision, the actual recurrence rate is not known due to paucity of reported cases...

Fibroma is one of the most common soft tissue benign tumors of the oral cavity. These masses represent hyperplasias instead of true neoplasm, which develop due to irritation to the mucosal tissue resulting in proliferation of the cells. Although so common in the oral cavity, its occurrence on the palate is rare, mainly due to fewer chances of trauma. Here, we report a case of palatal fibroma in a child diagnosed on the basis of clinical, radiological, and histological features. The case represents an extremely rare occurrence as unusual trauma due to thumb sucking seemed to be the only apparent traumatic factor in the palatal region...

OBJECTIVES: As intraosseous venous malformations (IVMs) of the zygoma are very rare and clinical features are not typical, a correct preoperative diagnosis may be difficult to make. This study presents 4 cases of IVM of the zygoma and gives a review of their clinical manifestations, radiographic features, preoperative diagnosis, and differentials. METHODS: The report of 4 cases was performed with an average 6-year follow-up. Medical records including clinical, radiographic, and histopathological information were reviewed...

OBJECTIVE: It is the aim of this study to evaluate if the CO2 laser can beneficially be applied for excising epulides. BACKGROUND DATA: The standard procedure for treating epulides involves the excision of the hyperplastic tissue followed in most cases by the removal of parts of the underlying bone and the final closure of the wound by a flap. The use of the CO2 laser for the treatment of epulides has been documented only in isolated case reports and very few case series...

Fibroma of tendon sheath, which is a benign soft tissue tumor, primarily affects the finger, hand, or wrist. It rarely involves the knee and only a few cases appear in the literature. Here, we report a case of fibroma of tendon sheath on the medial side of the knee, in a previously hardly reported location, and provide detailed imaging and histological findings. A 54-year-old man presented with his right knee pain and a palpable mass that had developed 3 months earlier. Magnetic resonance imaging showed isointensity in the soft tissue tumor on T1-weighted images, variable intensity on T2-weighted images, and contrast enhancement...

The techniques and outcomes of heart transplantation in the pediatric population continue to improve over the years, although the supply of organs remains limited. Donor-to-recipient size matching is critical, especially in neonates and small infants. We present a novel strategy for heart transplantation that includes the Lecompte maneuver because of the features of the donor allograft available in a 8-month-old patient with a cardiac fibroma. We discuss the basis principles for extending the indication of this procedure to exceptional transplantation scenarios and describe the results at long-term follow-up...

The psammomatoid ossifying fibroma (POF) is a rare and benign fibro-osseous lesion predominantly affecting the paranasal sinuses and orbits of children and young adults. The diagnosis and management of the lesion remains challenging. The present study reported a rare case of a large POF in a 39-year-old male patient. The patient had a 30 year history of a slowly growing tumor and this had resulted in right craniofacial deformity, as well as right lateral displacement of the eye ball. Due to the large tumor size, surgical removal of the lesion was the predominant treatment...

Ameloblastic fibroma (AF) is an uncommon true mixed odontogenic tumor, with a relative frequency between 1.5% and 4.5% of all odontogenic tumors. It may behave either as a true neoplasm or as a hamartomatous proliferation of odontogenic epithelium of the enamel organ and odontogenic mesenchyme of the primitive dental pulp. Frequently diagnosed between the first and second decades of life with 75% of cases was diagnosed before the age of 20 and present with a well-defined unilocular or multilocular radiolucencies...

Extraovarian sex cord-stromal tumor is an exceedingly uncommon entity that may cause a diagnostic dilemma clinically. We report a case of extraovarian fibroma with minor sex cord elements arising in the left broad ligament. The patient was a 66-year-old woman presenting with an intra-abdominal solid mass near the left ovary on magnetic resonance imaging. The tumor was located in the left broad ligament in contact with the left ovary and fallopian tube based on laparotomy findings. Histological examination revealed that the tumor was a fibroma that contained cell nests with aggregates resembling the Call-Exner bodies of granulosa cell tumors and irregularly shaped cell nests composed of undifferentiated sex cord-type cells...

We describe an interesting case of pleomorphic fibroma of the subungual region in a middle aged woman who presented with a recurrence of thickening, lateral ridging, and a midline split of the right third fingernail, 20 years after initial excision. Histology of the specimen demonstrated hyperchromatic stellate cells within the superficial corneum, which were CD34 positive, consistent with a pleomorphic fibroma. Pleomorphic fibroma is a rare mesenchymal neoplasm characterized by atypical spindled cells amidst a collagenous stroma...

Microscopic, heterotopic extraovarian sex cord-stromal proliferations have only recently been reported in the literature. We describe the largest series to date, of 30 cases of microscopic, incidentally detected, heterotopic extraovarian sex cord-stromal proliferation, in women aged 25-79 yr who had undergone surgery for a range of benign and malignant gynecologic conditions. In 14 patients the foci of proliferation comprised ovarian cortical stroma, in some cases with an ovarian fibroma-like appearance. Ten cases of adenofibroma and cystadenofibroma were also identified, including 1 Brenner adenofibroma; 2 cases comprised both ovarian cortical stroma and serous cystadenofibroma; 4 cases showed sex cord proliferation resembling microscopic adult granulosa cell tumors...
