Peripheral odontogenic keratocyst: Report of two new cases and review of the literature
2020
Peripheral odontogenic keratocyst (POKC) is a rare soft tissue entity showing the same histological characteristics of odontogenic keratocyst. Herein, we report two cases of POKC affecting the gingiva/alveolar mucosa. Case 1. A 43-year-old female was referred for evaluation of a painless well-defined nodular, sessile, non-tender swelling in the right maxillary buccal gingiva. No radiological alterations were observed. The patient was submitted to excisional biopsy and histological diagnosis was POKC. There were no signs of local recurrence after a 4-year follow-up. Case 2. A 63-year-old female was referred for evaluation of a painless well-defined nodular, sessile, yellowish swelling in the…
Percutaneous osteoplasty in treatment of bone lymphangiomatosis
2013
Primary bone lymphangiomatosis is a disease of unknown etiology that can cause lytic lesions in long bones, the pelvis, the spinal column and the cranium. We are presenting the case of a woman with localized bone lymphangiomatosis in the left knee. The authors believe this is the first case in which percutaneous osteoplasty was used in long bones for the treatment of bone lesions resulting from this disease showing good clinical results.
Tongue metastasis of cutaneous melanoma: Report of two cases and literature review
2018
Introduction Malignant metastases to the oral cavity are rare and metastatic melanomas of the tongue are considered exceptionally uncommon, with less than 10 cases published in the English literature so far. Case reports Two female patients in the 7th decade of life presented to our dental service with nodules in the tongue. Both patients had multiple metastases at the time of oral diagnosis and primary melanoma originated on the skin. An intra-oral incisional biopsy was performed under local anesthesia and the histopathologic analysis was characterized by the proliferation of atypical epithelioid cells displaying a poorly delimited cytoplasm and hyperchromatic nucleus which contained eosin…
Traumatic neuroma of the mandible: a case report with spontaneous remission
2014
Traumatic neuroma is a well-known disorder involving peripheral nerves, which occurs following trauma or surgery. The lesion develops most commonly in the soft tissues of the mental foramen area, lower lip and tongue. Intra-osseous lesions arising in jawbones are very uncommon. In this paper, we report a new case of an intra-osseous traumatic neuroma, discovered incidentally on a panoramic radiograph obtained for orthodontic documentation. In addition, the case herein described developed spontaneous remission, a situation not previously reported in the literature. Finally, we discuss relevant demographic, clinical, microscopic, immunohistochemical and treatment aspects of traumatic neuromas…
A rare case of oral multisystem Langerhans cell histiocytosis
2017
Langerhans cell histiocytosis (LCH) is a rare disorder characterized by high proliferation of Langerhans dendritic cells. LCH is a solitary or multifocal disease that primarily involves bone tissue and often affects children and young men. A 29 years-old Caucasian man was referred to the Oral Surgery Unit of George Eastman Hospital - Umberto I teaching hospital, with third degree mobility of teeth belonging to second, third and fourth quadrant. Panoramic radiograph showed multiple radiolucent areas with well demarcated borders on the right and left site of the mandible and on the left site of the maxilla. Extractions of compromised teeth and biopsy of the osteolytic tissue were performed. T…
Gossypiboma in the oral region: case report and literature review
2014
Gossypiboma is an inflammatory reaction to a foreign body, specifically composed of a cotton matrix left behind after surgery. The present study aims to present a case report of gossypiboma 23 years after a dental surgery and to make a literature review of the English language cases published on the issue. A 42-year-old woman was attended to evaluate complaints of pain on the right side of the maxilla. The patient reported that dental extractions in this region had been performed over a period of nearly 23 years. The panoramic radiograph demonstrated an opacity in the right maxillary sinus, which presented a spongiform aspect, irregularly shaped radiopaque image, as well as a rupture of the…
Photobiomodulation laser therapy in a Lenvatinib-related osteonecrosis of the jaw: A case report
2021
Background Medication-related osteonecrosis of the jaw (MRONJ) is a serious adverse drug reaction often presenting as a post-surgery complication that may interfere in the quality of the patient's life. In the last decade, additionally to bisphosphonates, other drugs have been associated with MRONJ including other antiresorptive, antiangiogenic or multitarget drugs such as levantinib. The data on MRONJ associated to lenvatinib is scarce with no guidelines for best management option. Our aim is to report a case of MRONJ associated with lenvatinib and the useful of a non-invasive management using local photobiomodulation (PBM) therapy with a 635nm diode laser. Material and methods A 61-year-o…
Retinoblastoma and mosaic 13q deletion: a case report
2021
Abstract Background Patients with 13q-syndrome are at risk of retinoblastoma when the RB1 gene, located in the chromosomal band 13q14.2, is deleted. This syndrome is frequently associated with congenital malformations and developmental delay, although these signs could be mild. Mosaic 13q-deletion patients have been previously reported in the literature; their phenotype is variable, and they may not be recognized. Case presentation Retinoblastoma diagnosed in a child with 13q-mosaicism confirmed in blood, oral mucosa, healthy retina and retinoblastoma. A second RB1 hit is present exclusively in the retinoblastoma sample (RB1 c.958C>T p.Arg320Ter). Other detected molecular events in retin…
Cavernous hemangioma of the parotid gland in adults
2014
Hemangiomas account for 0.4-0.6% of all tumors of the parotid gland and most of them occur in children, nevertheless in adults hemangiomas are very rare. We report the case of a 62 year old woman with a mass in the parotid right tail associated with fluctuating swelling episodes unrelated to meals and with a slowly progressive growth. The provisional diagnosis was a pleomorphic adenoma, so a right superficial parotidectomy was performed. During surgery, the macroscopic appearance makes suspect a vascular lesion. The histopathological result was a cavernous hemangioma. The classic clinical presentation of a parotid hemangioma is an intraglandular mass associated or not with skin lesions char…
Mercaptopurine Treatment in an Adult Man with Orbital and Intracranial Rosai-Dorfman Disease.
2016
Background. Rosai-Dorfmann disease (RDD) is a rare, idiopathic non-Langerhans cell histiocytosis, affecting children and young adults, that commonly presents as painless, massive cervical lymphadenopathy with fever, weight loss, and polyclonal hypergammaglobulinemia. Cervical lymphadenopathy and extranodal involvement are the main presentations. On the contrary, ophthalmic involvement and localisation in the central nervous system are rare.Case Report. An old man was admitted to our hospital for first seizure. Brain imaging studies revealed on the left an extra-axial thickening of the dura mater with enhancement and perilesional oedema, infiltrating the sphenoorbital fissure and an isointen…
