“…Molecular detection, FISH analysis, gene rearrangement and flow cytometry (FCM) analysis were not performed in most of these cases. Only a few cases were reported for FCM detection[19], immunoglobulin monoclonal gene rearrangement[1,21], PCR detection[23] or detection of bcl-2 mcr/JH fusion DNA sequences[1]. Our case was detected by the FISH method, and the result showed that only bcl-6 break-apart rearrangement (3q27) was observed in tumor cells of DLBCL.…”

“…We concluded that the most common subtypes of lymphoma were FLs (10 cases)[1-10], followed by Hodgkin’s lymphoma (4 cases)[11-14] and diffuse large B cell lymphoma (6 cases)[4,15-18]. The others were small lymphocytic lymphoma/chronic lymphocytic leukemia (3 cases)[19-21], mantle cell lymphoma (1 case)[22], extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue (1 case)[23], Lennert lymphoma (1 case)[24], peripheral T-cell lymphoma (2 cases)[25,26], and T lymphoblastic leukemia/lymphoma (1 case)[27]. In these patients, 4 cases of T-cell lymphoma and 25 cases of B-cell lymphoma were observed.…”

BACKGROUNDWarthin’s tumor (WT) is composed of several cysts that are lined with tall, bilayered oncocytic columnar cells and lymphoid stroma. Within WT, the two components rarely transform into carcinoma or lymphoma, and when it does, carcinoma is the most common type. Approximately 28 cases of lymphoma with WT have been reported, most of which were non-Hodgkin lymphomas, and only a few cases were Hodgkin lymphomas. In the present report, we studied a case of diffuse large B cell lymphoma (DLBCL) arising from follicular lymphoma (FL) with WT in the parotid gland and its immunophenotypic and genetic features.CASE SUMMARYA 67-year-old man presented with a slowly enlarging right cheek mass for 12 years, and the mass began to change in size over a 2-mo time period. Over time, the patient felt mild local pain and right cheek discomfort. His medical history included a hepatitis B virus infection for 20 years and 30 years of smoking. Gross examination of the excised specimen showed a gray-red and gray-white appearance and a soft texture lobulated external surface neoplasm that measured 9 cm × 8 cm × 7 cm and was well circumscribed by relative normal parotid gland tissue. In cross section, the cut surfaces of the neoplasm were multicystic and had a homogeneous scaly appearance. A small fluid was discovered in the cyst. Bilateral oxyphilic, cuboidal or polygonal epithelium cells and lymphoid intraparenchymal components were observed. Many medium- to large-sized lymphoid cells were observed diffusely in part of the neoplasm, and a few secondary lymphoid follicles were observed at the center or edge of the neoplasm. Immunohistochemical staining showed that the columnar oncocytic cells were positive for AE1/AE3; neoplastic cells located in coarctate follicular were positive for CD20, Pax-5, bcl-2 and bcl-6; and the adjacent diffusely medium- to large-sized lymphoid cells were positive for Pax-5, bcl-6, CD20, MUM-1, bcl-2 and CD79a. The bcl-6 (3q27) break-apart rearrangement was observed, and an Epstein Barr virus test was negative in the tumor cells. The patient survived 6 months after being diagnosed without any treatment.CONCLUSIONWT-associated lymphoma is a very rare neoplasm in the parotid gland. Most cases are B cell non-Hodgkin lymphomas and involve middle-age and older males. This case highlights the extremely rare association of DLBCL arising from FL with WT and the importance of deliberate evaluation of the WT intraparenchymal stroma. Molecular detection techniques have potential advantages in the diagnosis of lymphoma with WT.

“…Multiple tumours may be considered from three perspectives: according to their histological type with identical or different histology, time of development as synchronous or metachronous and localisation as unilateral, bilateral and multiple . The rare occurrence of other primary malignant salivary gland tumours could also be a result of malignant transformation of the epithelial or lymphoid component of WT …”

“…Recurrence of WT is probably associated with the multifocality of WT or inadequate excision . In rare cases—about 1%‐ malignant transformation of WT may occur, ie, squamous cell carcinoma or other carcinoma may develop from the epithelial component, and lymphoma may involve the lymphoid component . Some patients with malignant transformation of WT give a history of radiation.…”

“…In such cases of malignant transformation of the epithelial component of WT, the differential diagnosis includes squamous or mucous metaplasia, and metastases of extra‐salivary malignancies to a pre‐existing WT.

Warthin's tumour (WT) is a benign epithelial salivary tumour, one type of salivary adenoma. Histologically, WT is structured of two components, epithelial tissue that often lines cystic formations and lymphoid tissue in the tumour stroma. FNA is a reliable diagnostic approach in the diagnosis of salivary gland lesions allowing a highly accurate categorization of benign tumour‐like lesions, benign tumours and malignant tumours. In the proposed Milan reporting system of salivary gland lesions, WT is categorized in the IVA group of benign neoplasms. Accurate cytological diagnosis is straightforward when three characteristic components are present: oncocytes, either isolated or associated in clusters, lymphocytes and lymphoid cells and often an inflammatory/necrotic‐like substance. Also, specific features of scintigraphy and radiological imaging contribute to the diagnosis of WT. WT is categorized according to Seifert G. et al in 4 types, depending on the proportions of the epithelial component and lymphoid stroma. Differential cytopathological and pathohistological diagnosis include other salivary gland lesions with lymphoid, oncocytic epithelial and cystic components. In some cases, such as the metaplastic WT variant, there are additional cytopathological and histological diagnostic difficulties. Moreover, bilateral, multicentric or multiple and infrequently seen extra‐salivary localizations of WT are associated with further cytopathological diagnostic difficulties. Also, a rare possibility of malignant transformation of the epithelial or lymphoid component of WT as well as possible association with other primary tumours remains a challenge in accurate cytopathological and histological diagnosis of WT.

Follicular Lymphoma Diagnosed in Warthin Tumor: A Case Report and Review of the Literature

Warthin tumor is one of the most common benign salivary gland tumors. It is unusual and difficult to diagnose follicular lymphoma within the lymphoid tissue of Warthin tumor. We present a rare case of a 69-year-old man with systemic follicular lymphoma initially diagnosed in a Warthin tumor. Lymphomas occurring within Warthin tumors are rare, however, follicular lymphoma is most commonly reported. Because these patients require further treatment depending on the stage of a disease, it is important for a pathologist to review the histology of Warthin tumors diligently to identify occult lymphomas.
