Oral involvement in neuroblastoma
Michael H. Stern, DDS James E. Turner, DDS Thomas P. Coburn, MD, Memphis
Eighty-three patients with
neuroblastoma were
examined retrospectively to determ ine the fre quency with which this malignancy affects the os seous structures of the oral cavity. These struc tures were involved in 21 (25%) of all patients and in 21 (49%) of the 43 with bone métastasés as judged from clinical, radiologic, and pathologic findings. Evidence of oral involvement led to diag nosis in two instances and was discovered during the initial evaluation in ten of the 21 patients with facial manifestations. The most common clinical signs were facial or intraoral, swellings or both, loose or displaced teeth, and paresthesia. The most important radiologic findings were lytic le sions, expansion of the dental follicle, and poorly defined borders around the crypts of developing teeth. This study indicates that oral involvement in neuroblastoma is much more common than was previously thought, and that clinical and radio logic evidence of jaw metastasis may be of value in early diagnosis.
Neuroblastoma, a highly malignant tumor of sympathetic nervous tissue origin,1 is the sec ond most common malignancy of children, pre ceded only by leukemia.2 It may occur as a lo calized lesion but is usually widespread at the time of diagnosis.1-4 Common sites of metas tasis are the lymph nodes, bone, liver, and lungs.5,6 The bones most frequently affected are the femur, humerus, skull, and pelvis.7 3 46 ■ JA D A , V o l. 88, F e b ru a ry 1974
Although the skull is a frequent site of meta static neuroblastoma, only 12 isolated cases of oral metastasis have been reported to date.2,710 Our experience with this tumor suggested that involvement of the oral cavity was much more frequent than indicated by published findings. A retrospective study was therefore conducted to test this impression and to determine the char acteristics that mark the spread of this disease to the jaws.
Patients
The radiographs and records of 83 patients with neuroblastoma treated at St. Jude Children’s Research Hospital between March 1962 and Oc tober 1972 were reviewed. In each instance the diagnosis was established from a histologic ex amination of biopsy tissue. Clinical, radiograph ic, and pathologic reports were used to deter mine the frequency and extent of oral involve ment. The race, age, and sex of each patient with evidence of jaw metastasis are given in the Ta ble. The median age at diagnosis for this group was 3 years (range: 10 months to 8 years, 1 month).
Results
The adrenal gland was the site of tumor origin in most patients in this series. Other areas com monly involved were the lymph nodes, bones, and bone marrow. Symptoms were variable and nonspecific, consisting largely of anorexia, fe ver, pain, and irritability. The main initial phys ical findings were palpable abdominal masses,

The mandible was af fected in 15 o f these patients, the maxilla in one, the zygom a in one, and a com bination o f sites in the remaining four (Table). Oral evidence o f neuroblastom a w as the presenting complaint in tw o patients and was found on physical exam ination during diagnostic procedures in another ten. In the remaining patients, the mean time from diagnosis until the appearance o f jaw le sions was 8.1 months. The oral clinical signs o f neuroblastom a were facial sw elling, intraoral m asses, loose or dis placed teeth, and alterations in nerve function (Table). Facial sw elling was unilateral and quite prominent in eight patients (Fig 1). Although the sw elling closely resem bled that caused by ab scessed teeth, it w as usually not accom panied by pain. Intraoral m asses o f various sizes were found in 12 patients, mainly in association with lo o se or displaced teeth (F ig 2). Four patients experienced sudden neurological changes as in348 ■ JADA, V o l. 88, F e b ru a ry 1974

Radiographic changes con sisted o f ill-defined borders around the crypts o f developing teeth, expansion o f the dental fol licle, displaced or floating teeth or both, and lytic lesions (Table). L oss o f definition o f the white borders around dental crypts was seen in seven patients. This change was confined to the premolar and molar areas and ranged in appear
ance from a decreased w hiteness to a com plete, loss o f crypt definition (F ig 3). Unilateral (F ig 4) or bilateral (Fig 3) expansion o f the dental fol licle with displacem ent o f the tooth bud w as seen in nine patients. T ooth displacem ent was appar ent in five patients. T he absence o f supporting bone around these teeth som etim es suggested the appearance o f floating teeth (Fig 5, 6). Lytic lesions, the most com m on pathologic change, were seen in 16 of the patients. T he lesions were confined to the posterior body and ramus area o f the mandible, and their appearances ranged from

D is c u s s io n Oral involvem ent by neuroblastoma, formerly thought to be rare,2-7'10 was seen in 25% (21 o f 83) o f the patients treated for this malignancy at St. Jude Children’s Research H ospital dur ing the past ten years. Improved diagnostic tech niques such as dental panoramic radiography, as w ell as a growing aw areness o f the oral com plications o f this disease, have been important 350 ■ JADA, V o l. 88, F e b ru a ry 1974
factors in the recognition o f mandibular and maxillary m etastases. T he actual incidence o f or al m etastasis may be greater than that found in this limited series because the natural history o f neuroblastoma is one o f widespread involvem ent with an affinity for bone. Since the skull is one o f the areas m ost frequently affected by this malig nancy (57% in this series), w e would expect to find a higher frequency o f oral involvem ent as larger numbers o f patients are exam ined for this com plication. Orofacial signs can be prominent early in the course o f neuroblastoma, and a patient may have oral sym ptom s before any other m anifestations o f the disease. In this study prominent oral sw ell ings led to a diagnosis o f neuroblastom a in tw o patients, and oral findings were present at the time o f diagnosis in half the number o f patients with jaw lesions. T he m ost com m on early find ings w ere facial or intraoral swellings due to tu mor infiltration, loose or displaced teeth, and neurological disturbances with no history o f as sociated trauma or infection. W hereas bone pain was often an early physical finding, intraoral or facial pain was noted only late in the course o f the disease. Although oral radiographic findings in neuro blastom a are not diagnostic, panoramic radiog raphy o f osseou s structures o f the oral region has been included at this hospital as a routine screening procedure for all our patients. T he present findings indicate that certain radiograph ic changes in the jaw s o f young children should com pel one to include neuroblastom a in the dif ferential diagnosis o f jaw lesions. Such altera tions are destruction o f the white sclerotic bor der o f the dental crypts, expansion o f the den tal follicle, displacem ent o f teeth, floating teeth, and destructive lucent lesions with irregular out
lines. As shown by this study, oral involvement in neuroblastoma is not rare. M oreover, recogni tion of the clinical and radiologic features pecu liar to neuroblastoma that has spread to the oral structures may be of prime importance in the establishment of an early diagnosis. By recog nizing one or more of these signs and by referring the patient to a physician for immediate eval uation, the dentist can provide an essential step in the detection of this malignancy.

Foley’s Footnotes ------------------R epeatedly in th e lay literature nom inations have been presented fo r "th e m eanest m an .” Several of them have a relation to dentistry, usually to dentures. An episode in a short story published in th e A tla n tic M o n th ly of June 1876 gives a good exam ple of this type of relationship. ‘Lisha M anchester had been frettin ’ at th e girls because they w ould hev their m other buried with her false teeth in. T h e teeth w a ’n’t none of his g e ttin ’, but he said they could be m ade over fo r him, or they’d fetch som eth in’ to sell, and it was a dretful w aste to bury ‘em , and he kept on so about 'em that they had to watch him pretty close fo r fear h e ’d take 'em out, say w h at they would! A nother “ m eanest m an” nom ination appeared in H a rp e r's N e w M o n th ly M a g a z in e of N ovem ber 1883. T h e edito r com m ents on “ a rivalry In various parts of th e country as to w h at place can produce th e m eanest m an .” T h e prize is claim ed by a man in th e W est w ho unfortunately lost his w ife just after he had procured her a new set of teeth . Th e husband fe lt th e loss deeply, because she was a good w om an, and pon dered how he could lessen his cost. B efore th e funeral he rem oved th e set of te eth and took them back to the dentist, with the request th a t he should have his m oney back, as they had been very little used. A noth er recom m endation for dishonorable m ention in this category of m eanness was an old curm udgeon of C oncord, NH. He m ade his w ife keep a com plete cash account. During one of his weekly exam inations of her financial report he exploded: “ Look here, Sarah, m ustard plasters, 50 cents; three teeth extracted, tw o dollars!
