Multiple myeloma presenting with extensive oral and perioral amyloidosis

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.

Oral lesions and lymphoproliferative disorders

Lymphoproliferative disorders are heterogeneous malignancy characterized by the expansion of a lymphoid clone more or less differentiated. At the level of the oral cavity, the lymphoproliferative disorder can occur in various ways, most commonly as lymphoid lesions with extranodal externalization, but sometimes, oral lesions may represent a localization of a disease spread. With regard to the primary localizations of lymphoproliferative disorders, a careful examination of the head and neck, oral, and oropharyngeal area is necessary in order to identify suspicious lesions, and their early detection results in a better prognosis for the patient. Numerous complications have been described and frequently found at oral level, due to pathology or different therapeutic strategies. These complications require precise diagnosis and measures to oral health care. In all this, oral pathologists, as well as dental practitioners, have a central role in the treatment and long-term monitoring of these patients.

Macroglossia Secondary to Systemic Amyloidosis: Case Report and Literature Review

Amyloidosis is characterized by an abnormal extracellular deposition of amyloid in different tissues and organs, where it usually causes some type of dysfunction. Its cause is unknown. The two main forms of amyloidosis are systemic and localized; the latter is rare. No satisfactory treatment for systemic amyloidosis has been discovered, and mean survival is poor, ranging from 5 to 15 months depending on the presence or absence of multiple myeloma. We report a case of primary systemic amyloidosis in a 71-year-old man. The diagnosis of amyloidosis was established by tongue biopsy, and its systemic nature was identified by analysis of aspirated abdominal fat. At the 1-year follow-up, the patient's clinical condition had not changed, and he was thereafter lost to follow-up.

Oral candidiasis and multiple myeloma. An unusual association

A case of oral candidiasis possibly associated with multiple myeloma is presented. A review of the literature and a pertinent discussion relevant to this unusual association are offered.

Tongue, primary amyloidosis, and multiple myeloma

A case of macroglossia and resulting apertognathia because of primary amyloidosis in a 65-year-old man with multiple myeloma is described. In addition, a retrospective study of the oral manifestations of primary amyloidosis and multiple myeloma in the last 15 years is reported.

What to look for after you say 'open wide'. A guide to examination of the oral cavity

Abnormal conditions of the oral cavity can have a significant impact on overall health, yet during many ostensibly complete physical examinations, the area is given only a perfunctory glance. Drs Thomas and Bender present guidelines for systematic, comprehensive evaluation of the oral cavity and provide case reports and figures to illustrate typical important findings.

Multiple myeloma and bullous lichenoid lesions: an unusual association

Many associations of lichenoid reactions have been described but this case appears to be a previously unreported association--with multiple myeloma. This case also demonstrates the necessity of a mucosal biopsy with adequate hematologic and serologic investigations to obtain a definitive diagnosis.
