Pseudolymphoma of the tongue mimicking Hodgkin' disease (A Case Report)

Eosinophilic Ulcer of the Tongue: A case report with immunohistochemical study.

“…The histiocytic component was mitotically active and sometimes showed apparently atypical features. Such monotonous, diffuse proliferation is likely to be misdiagnosed as malignant lymphohistiocytic tumor (39)(40)(41)(42)(43)(44)(45)(46) . However , neoplastic changes have never been documented until now .…”

“…In summary, the importance of EU is that it can pose considerable problems diagnostically. Clinically, the lesion is highly suspicious for oral cancer and histologically misdiagnosed as lymphohistiocytic tumor (39)(40)(41)(42)(43)(44)(45)(46) . Both clinicians and pathologists should avoid such risks.…”

Oral Eosinophilic Ulcer, an Epstein-Barr Virus-Associated CD30+ Lymphoproliferation?

“…Adding to this list, identical clinical features exclusively seen in nursing infants are known as Riga-Fede disease [19]. In a similar manner, the condition has been referred to histopathologically as reparative lesion [20], lymphohistiocytic lesion [21], atypical histiocytic granuloma [22,23,24,25] and pseudolymphoma [26,27,28]. Nevertheless, these different clinical and histopathological terms have common cardinal features that are not present together in any other similar disease at this location.…”

Benign Lymphoid Hyperplasia of the Tongue Masquerading as Carcinoma: Case Report and Literature Review

“…Benign lymphoid hyperplasia (BLH) of the oral cavity and especially of the tongue is an uncommon, poorly understood entity which may be confused clinically and histologically with malignant lymphoma. 1,2 A limited number of publications addressing this subject are available in the literature and little is known about the etiology, natural history, and distinctive histologic features of these lesions. The posterior hard palate is the most common site to be affected.…”

“…A small number of patients have developed recurrences after local excision but have not shown any evidence of a malignant process after long-term follow-up. 2,3 Morphologically, BLH is characterized by a dense lymphoid infiltrate within the lamina propria and submucosa. The squamous epithelium is normal or slightly hyperplastic.…”
