This paper presents an unusual case of gingival ALCL, which mimicked a benign hyperplastic lesion that occurred in a 57-year-old white man representing the first clinical manifestation of acquired immunodeficiency syndrome (AIDS). The patient was referred to the Dental Clinic of PUCPR complaining of a lobulated nodule on the gingiva of his upper central incisors. The presence of advanced chronic periodontitis and dental plaque raised suspicion for a benignancy. An excisional biopsy was performed, and large pleomorphic cells with an abundant cytoplasm, sometimes containing prominent nucleoli and “Hallmark” cells, were observed through hematoxylin and eosin staining. The tumor cells showed strong CD30 expression, EMA, Ki-67, and LCA, and negative stain for p80NPM/ALK, CKAE1/AE3, CD20, CD3, CD56, and CD15. The final diagnosis was ALCL (ALK-negative). Further laboratory tests revealed positivity for human immunodeficiency virus (HIV). The patient was submitted to chemotherapy, but four months after diagnosis, the patient died due to pneumonia and respiratory failure. Oral anaplastic large-cell lymphoma (ALCL) is a rare disorder. Only 5 cases involving the gingiva have been reported, and to our knowledge, this is the first case reported of the ALCL, which mimicked a hyperplastic benignancy as the first clinical manifestation of AIDS.

BACKGROUND The epidermal growth factor receptor (EGFR) and the extracellular matrix metalloproteinase inducer (EMMPRIN) have been identified as oncologically important targets. This study aimed to evaluate the immunoexpression of EGFR and EMMPRIN in a series of cases of head and neck squamous cell carcinoma (HNSCC). METHODS Forty-five cases of HNSCC were selected for this study and evaluated with anti-EGFR and anti-EMMPRIN antibodies. The percentage of positive cells was determined assessing to the following categories: score 1 (staining in 0-50% of cells), score 2 (staining in 51-75% of cells), and score 3 (staining in >75% of cells). Immunostaining intensity was graded according to the following parameters: score 1 (absent/weak expression) and score 2 (strong expression). RESULTS For EGFR, a predominance of high median scores was observed in cases of both histological grades of malignancy and in different clinical stages (p>0.05). For EMMPRIN, a statistically significant difference was observed between the histological grades of malignancy (p=0.030). Regarding the immunostaining intensity of EMMPRIN, it was observed a predominance of score 1 in cases with stages I/II, whereas most cases with stages III/IV presented score 2 (p=0.032). Considering the anatomical location, most cases of buccal floor presented higher median score of EMMPRIN in comparison with the other sites (p=0.015). CONCLUSIONS These findings suggest that both proteins are potential targets for cancer therapy and EMMPRIN can be used as a prognostic marker of a more aggressive biological behavior in patients with HNSCC.
