The higher incidence of immunosuppressive status is increasing in the last years the diagnosis of tumours of unusual location and behaviour. We present the case of a HIV-seropositive 41 years-old woman, bearing of high dysphagia and pharyngolalic voice. The exploration showed a tumour emerging in lingual tonsil and spreading out to hypopharynx and larynx. No lymph nodes were observed. Its resistance to chemotherapy made necessary its surgical removal.
