Multiple Myeloma presenting as Gingival mass

The Bloody Crossroads: Interactions between Periodontitis and Hematologic Diseases

Periodontitis is a common oral condition that can have a significant impact on the overall health of the body. In recent years, attention has been paid to potential relationships between periodontitis and various hematological disorders. This publication aims to present information available in the literature on this relationship, focusing on examples of red blood cell disorders (such as aplastic anemia and sickle cell anemia) and white blood cell disorders (such as cyclic neutropenia, maladaptive trained immunity, clonal hematopoiesis, leukemia, and multiple myeloma). Understanding these associations can help physicians and dentists better diagnose, monitor, and treat patients associated with both groups of conditions, highlighting the need for interdisciplinary care for patients with oral disorders and hematologic diseases.

Multiple myeloma with oral manifestations as maxillary ulceroproliferative lesion: A case report

ABSTRACT

Multiple Myeloma (MM) is the most common malignant neoplasm of bone and can manifest with different clinical features in oral cavity. MM lesions in skull and jaws have characteristic punched out lesions but are often confused with meningioma when they occur in skull as solitary lesions. We report a case of MM that reported in oral cavity for which prompt diagnosis was done, but there were symptoms that persisted for years and a skull lesion that was diagnosed and treated as meningioma before MM was diagnosed from the oral lesions. This is the first case where the patient has been actually treated for meningioma, and then diagnosed with MM after months. In that case, SBP or MM should be included in the differential diagnosis of a dural mass, particularly when a patient is complaining of neurological deficits. Also, the role of oral physician in the diagnosis of MM should be stressed in diagnosis and multidisciplinary management, thus facilitating better clinical outcomes.

Multiple myeloma masquerading as mandibular medication-related osteonecrosis of the jaw: a case report

This is a unique case report of a 67-year-old female diagnosed with multiple myeloma and extensive use of intravenous bisphosphonate, whose clinical and radiographic presentation of an oral lesion made it challenging to confirm its definitive diagnosis. This patient was referred to the dental service for a suspected medication-related osteonecrosis of the jaw (MRONJ). Clinically, the lesion was located underneath a fixed partial denture in the left posterior mandible. There was a purulent swelling on the lingual side of the fixed partial denture, and a hyperplastic exophytic lesion on the buccal side of the bridge. Panoramic radiograph showed a well circumscribed radiolucent lesion in the left mandible. A biopsy of the gingival lesion on the buccal aspect was inconclusive. As the positron emission tomography scan showed lytic lesions, oral manifestation of multiple myeloma could not be ruled out. A computed tomography-guided biopsy of the left mandible showed plasma cell neoplasm in the histological analysis. Upon confirmed diagnosis, the patient was treated with 20Gy to the left mandible and subsequent debridement of the loose necrotic bone. Following treatment, this gingival lesion resolved completely, and the tumour has remained stable till date.

Identification of Gingivitis-Related Genes Across Human Tissues Based on the Summary Mendelian Randomization

Periodontal diseases are among the most frequent inflammatory diseases affecting children and adolescents, which affect the supporting structures of the teeth and lead to tooth loss and contribute to systemic inflammation. Gingivitis is the most common periodontal infection. Gingivitis, which is mainly caused by a substance produced by microbial plaque, systemic disorders, and genetic abnormalities in the host. Identifying gingivitis-related genes across human tissues is not only significant for understanding disease mechanisms but also disease development and clinical diagnosis. The Genome-wide association study (GWAS) a commonly used method to mine disease-related genetic variants. However, due to some factors such as linkage disequilibrium, it is difficult for GWAS to identify genes directly related to the disease. Hence, we constructed a data integration method that uses the Summary Mendelian randomization (SMR) to combine the GWAS with expression quantitative trait locus (eQTL) data to identify gingivitis-related genes. Five eQTL studies from different human tissues and one GWAS studies were referenced in this paper. This study identified several candidates SNPs and genes relate to gingivitis in tissue-specific or cross-tissue. Further, we also analyzed and explained the functions of these genes. The R program for the SMR method has been uploaded to GitHub(https://github.com/hxdde/SMR).

Oral health status of patients with multiple myeloma

Objective

To describe the oral health status of patients with multiple myeloma and compare to a control group.

Materials and methods

The medical history of the studied subjects was obtained from the medical records and through interviews. Trained examiners evaluated the oral mucosa, teeth, periodontium and imaging aspects. The dental status was evaluated by the decayed, missing and filled teeth index. The presence of bone lesions was investigated with cone beam computer tomography images of the jaws.

Results

The most common oral mucosa features were paleness (31%) and coated tongue (14.3%) in the multiple myeloma group (N = 42); and coated (21.4%) and fissured tongue (10.7%) in the control group (N = 28). The mean DMFT index of patients with multiple myeloma was high, but not significantly different from controls (14.57 versus 19.69, p = 0.975). Hypodense lesions suggestive of multiple myeloma were observed in the jaws of 73.8% of the patients. Hypodense lesions related to teeth were detected in 33.3% of the patients and in 53.6% of the controls (p = 0.832).

Conclusions

The studied population of multiple myeloma patients presented many oral health issues that needed attention. Thus, oral care should be included in the routine treatment to improve the quality of the oral status in these patients.

Multiple myeloma presenting as an unhealed extraction socket: Report of a case with brief review of literature

Multiple myeloma (MM) is a relatively rare malignant hematological disease, which is characterized by a monoclonal malignant proliferation of plasma cells that causes osteolytic lesions. Maxillofacial presentations in patients with MM are not uncommon, but because the symptoms are varied, it is very difficult to diagnose MM in this region especially in patients with initial oral involvement. Furthermore, maxillofacial manifestations as an initial sign or symptom are scarce. We report a case of a 40-year-old male patient who presented with an unhealed socket in lower left back tooth region for the past 2 months. The panoramic radiograph revealed a multilocular radiolucency. Histopathological examination of the biopsy specimen revealed a malignant hematopoietic neoplasm formed by plasmacytoid cells. Radiographic survey and immunoreactivity for CD 138 and lambda chain antibody further confirmed the diagnosis of MM.

Toothache as the initial symptom of plasma cell myeloma

Patients with plasma cell myeloma may initially present to their dentists or dental surgeons with toothache, loose teeth, or gingival masses. An X-ray of the jaw can reveal osteolyses. In addition, accumulation of monoclonal light chains in AL-amyloidosis can lead to macroglossia. It is prudent that the dentist or dental surgeon recognizes the underlying disease and refers the patient to the oncologist or hematologist for further workup to prevent the complications of plasma cell myeloma such as renal impairment, fractures, bone pain, infections, hypercalcemia, anemia, or heart failure. Another area where the dentist or dental surgeon is involved with patients suffering from plasma cell myeloma is prevention and therapy of osteonecrosis of the jaw, occurring after administration of bisphosphonates or denosumab for osteolytic bone disease. The case report presented here shows a patient complaining of toothache for whom recognition of a systemic disease by the dentist led to the diagnosis of plasma cell myeloma, highlighting the need for interdisciplinary cooperation. As recent years have seen many changes in the management of patients with plasma cell myeloma, an update for dentists and dental surgeons is warranted.

Can dentists detect multiple myeloma through oral manifestations?

Objective

To review published data on oral manifestations of multiple myeloma.

Methods

An electronic database search was performed of articles published from 1971 to November 2016 in order to identify studies that reported oral manifestations of patients with multiple myeloma. Case reports and case series with oral manifestations of multiple myeloma in English were included in the study. An additional search was performed of the references of the selected articles.

Results

Thirty-seven articles that reported 81 patients with oral manifestations of multiple myeloma were selected: 30 case reports (82%) and seven case series (18%). The most common clinical features in the dental cavity were swelling (65.4%), bone pain (33.3%), paresthesia (27.1%) and amyloidosis lesions (11.1%). Osteolytic lesions detected on imaging exams were reported in the majority of the patients (90.1%) as plasmacytomas or ‘punched-out’ lesions.

Conclusions

Swelling and osteolytic lesions represent the most common clinical and radiographic signs of the jaws relating to multiple myeloma, respectively.

Maxillary Swelling as the First Evidence of Multiple Myeloma

Multiple myeloma is a malignant neoplasm of plasma cells characterized by proliferation of a single clone of abnormal immunoglobulin-secreting plasma cells. Since the amount of hemopoietic bone marrow is decreased in the maxilla, oral manifestations of multiple myeloma are less common in the maxilla than in the mandible. We report the case of 33-year-old Japanese man who presented with a mass in the right maxillary alveolar region. Computed tomography and magnetic resonance images showed a soft tissue mass in the right maxilla eroding the anterior and lateral walls of the maxillary sinus and extending into the buccal space. The biopsy results, imaging, and laboratory investigations led to the diagnosis of multiple myeloma. This case report suggests that oral surgeons and dentists should properly address oral manifestations as first indications of multiple myeloma.

Facial Swelling as a Primary Manifestation of Multiple Myeloma

Facial swellings are commonly encountered in the dental office, the cause of which could range from a congenital etiology to an acquired one or it may even be a manifestation of an underlying systemic disease. The clinician must have a thorough knowledge of the various clinical and imaging manifestations and the sites of occurrence of the various conditions to arrive at the appropriate diagnosis. Facial swellings can be classified into different groups which include acute swellings with inflammation, nonprogressive swellings, and slowly or rapidly progressive swellings. The various imaging modalities like CT and MRI are useful for assessing the extent of the swelling as well as evaluating the soft tissue and osseous involvement of the swelling. Multiple myeloma represents clonal proliferation of plasma cells and is a condition in which a facial swelling might be present, though not common. This paper reports a case of a patient with a unilateral facial swelling, which on investigation led to a diagnosis of multiple myeloma.

Multiple osteolytic lesions

Several systemic diseases initially present with various oral manifestations. Investigation of these oral symptoms may at times lead to the diagnosis of grave underlying life-threatening conditions. We present one such case, where the patient manifested with gross enlargement of the mandible, along with lesions in the lower limbs. These lesions were the initial manifestation and on further investigations the patient was diagnosed with multiple myeloma.

Maxillary pain is the first indication of the presence of multiple myeloma: A case report

Multiple myeloma is a primary malignancy of bone marrow characterized by the clonal proliferation of plasma cells and production of monoclonal immunoglobulin. The disease occurs more frequently in males, with the average age at diagnosis being ∼60 years. The first manifestation of multiple myeloma is varied and depends on the sites and extent of involvement. The predominant clinical symptoms of multiple myeloma are associated with bone pain and renal dysfunction. Neoplastic cells usually produce large amounts of monoclonal immunoglobulin light or heavy chains that can be detected in serum or urine, while plasmacytoma may be identified on marrow biopsy. The present study reported on the case of a 69-year-old male patient presenting with a complaint of a painful lesion in the left maxilla. Physical examination, imaging, laboratory investigations and biopsy were conducted, confirming the diagnosis of multiple myeloma. The results obtained suggest that the dentist should address oral manifestations as first indications of multiple myeloma.
