Primary laryngeal lymphoma: a diagnostic challenge

Catarina Lombo, Carlos Matos, Rui Fonseca

Abstract


Lymphomas of head and neck constitute 5-15% of malignancies in this region. However, its primary occurrence at the larynx is exceedingly rare due to the paucity of lymphoid tissue. Here, we reported a case of a 41 year old male who presented with a 1 month history of hoarseness and odynophagia. The examination revealed right vocal cord palsy and an ipsilateral subglottic exudate, that was misdiagnosed as infectious disease. The lesion quickly progressed to airway obstruction, requiring a tracheotomy. Multiple biopsies under general anesthesia were needed before reaching the final diagnosis of diffuse large B-cell lymphoma, Epstein-Barr positive. Selected treatment modality included 3 cycles of chemotherapy followed by radiotherapy in moderate dose with complete remission after 2 years of follow up. The tracheotomy was removed, however, the patient did not recover vocal quality. This case highlighted the heterogeneous presentation of extra-nodal head and neck lymphomas and emphasized the need for suspicion of neoplasm when an infection doesn’t respond to maximal medical therapy.
