Here, we report a case of non-Hodgkin's lymphoma (NHL) in a 51-year-old male patient with manifestations in the oral cavity, presenting as multiple ulcers and swelling. The other findings include the small lymphocytic lymphoma with extranodal involvement, distortion of facial symmetry, and cervical lymphadenopathy. A comprehensive evaluation by the dental clinician is crucial to identify the disease in its initial stage, for better prognosis and management. Early and prompt diagnosis of NHL by fine-needle aspiration cytology supplemented by immunocytochemistry may aid in early prevention of the disease with further investigations of biopsy and immunohistochemistry.

| Introduction|| |
Hodgkin's lymphoma (HL) has an incidence rate of 1%–4% in the extranodal sites, whereas approximately 40% of non-HL (NHL) cases occur in the extranodal sites and commonly involve the cervicofacial region. NHL has twice the preponderance over extranodal onset as compared with HL. The gastrointestinal tract is the most common site of extranodal disease, occurring in over 50% of patients, followed by the head-and-neck region which varies from 11% to 33%. A very small proportion of head-and-neck NHLs occur within the oral cavity. We have reported a case of NHL where oral manifestations of NHL are predominant over the tongue. There are very less literature and reported cases of oral manifestations of NHL. In 3%–4% of these NHL cases, the initial manifestation is in the oral cavity and the features are quite perplexing. They present with a wide array of sign and symptoms like in acquired immune deficiency syndrome, squamous cell carcinoma, salivary gland tumors, space infections, periodontal disease, and osteomyelitis, which emulate clinical conditions such as patients with oral lesions for which they frequently report to a dental surgeon. These traits of NHL cause difficulty in the early diagnosis, prognosis, and management. The case report highlights the extraoral and intraoral features of NHL in a 51-year-old male who presented with a swelling involving the anterior part of the tongue in the dorsum region and was diagnosed as small-cell NHL CD20 positive. The patient was treated with chemotherapy, and after 4 weeks of administration of chlorambucil and prednisolone, the swelling in the tongue subsided completely.
| Case Report|| |
A 51-year-old African male originating from the central part of Africa reported with complaints of swelling in the face and neck region, multiple ulcers in the oral cavity, and difficulty in eating food for 8–9 weeks. On examination, a swelling in the anterior part of the tongue dorsum region and along the left side of the neck and below the chin was found. Later, a similar kind of the swelling was noticed in the armpits and in the groin region. Concurrently, he also developed multiple ulcers in the various region of the oral cavity. The swellings in these regions gradually increased to the present size. There was a history of weight loss. The patient had sought numerous medical consultations and was put on various antibiotics without any relief. The multiple nonhealing ulcers and difficulty to eat made him report to a dentist.
On general examination, multiple lymph nodes in the cervical, inguinal, and intra-abdominal region were palpable. There was obvious facial asymmetry with enlargement of lymph nodes in the submental, submandibular (level 1), and upper jugular (level 2) region, with the largest one measuring approximately 5 cm × 3.5 cm in size. The lymph nodes were asymptomatic, fixed, and firm in consistency. The skin overlying the lymph nodes was normal without any secondary changes [Figure 1] and [Figure 2].

Intraoral examination revealed multiple large ulcers on the upper lip, buccal vestibule, and floor of the tongue. The glaring finding was a swelling in the anterior part of the tongue in the dorsum region, measuring 2 cm × 2.5 cm in size [Figure 3] and [Figure 4].
Ultrasonography of the abdomen was done where hepatosplenomegaly retroperitoneal and mesenteric lymphadenopathy was detected [Figure 5]. Further investigations were ordered to diagnose the condition; fine-needle aspiration cytology (FNAC) of the upper jugular group bone marrow biopsy was done. FNAC smear showed predominantly monomorphic population of small lymphocytes in a hemorrhagic background with lymphocytes showing irregular margins with prominent one or two nucleoli. Minimal atypia was seen. Bone marrow biopsy report was suggestive of chronic lymphocytic leukemia (CLL). To confirm the diagnosis, biopsy of the right submandibular lymph node was done. Microscopic examination report unveiled a diffuse infiltrate by a monomorphic population of small lymphoid cells. Immunohistochemistry reported that tumor cells were CD45 and CD20 positive indicative of small-cell NHL.
The patient was treated with chemotherapy, and after 4 weeks of administration of chlorambucil and prednisolone, the facial symmetry was restored, the oral lesions, i.e., ulcers and swelling in the tongue, subsided completely [Figure 6] and [Figure 7].
| Discussion|| |
Based on the lymphoid cell lineage and its behavior, more than 20 different subtypes have been identified. The majority are of B-cell lineage, namely diffuse large B-cell lymphoma, small lymphocytic lymphoma (SLL), and Burkitt lymphoma.,, SLL is clinically related to CLL which also involves the B-cells along with lymph node involvement. The CLL can be differentiated from NHL by immunohistochemistry studies, which identifies distinct proteins on the surface of the B-cells known as CD20 and CD45. SLL is primarily seen in the middle age and above, with a mean average age of 55–61 years. The male-to-female predilection for SLL is approximately 2:1., The early presentation of SLL is painless involvement of a cervical group of lymph nodes, namely the submental, submandibular, and jugular groups; lymph nodes of the armpit and groin region are also involved. The patient may also present with symptoms of fever, night sweat, and weight loss. The above-mentioned findings coincide with our case presentation.
A comprehensive evaluation is necessary for the early diagnosis and treatment. The investigation should include FNAC, biopsy, and immunohistochemistry studies. Timely diagnosis and early referral reduces the morbidity in these patients.
| Conclusion|| |
Refractory oral lesions and cervical lymphadenopathy mimicking the malignancy should forewarn the clinician for a comprehensive evaluation consisting of detailed clinical examination and histopathological and radiological procedures for timely diagnosis and appropriate treatment. Lymphomas have a good prognosis, when timely treated, they reciprocate very well to chemotherapy and oral lesions begin to heal completely.
