[Peritoneal metastasis from regionally advanced hypopharyngeal cancer].

A very rare case of patient with locally advanced hypopharyngeal cancer with solitary, large peritoneal metastasis was presented. Diagnostic imaging excluded other organs metastases (lungs, liver, bones). At 62-old patient with advanced hypopharyngeal cancer (T4N2b) a dynamical nodal progression (within 1.5 months) without primary tumour progression was observed, and number of metastatic nodes was increased from 2 to 9. Simultaneously, a solitary peritoneal metastasis was detected and other metastases were excluded. Stage of disease was determined as T4N2cM1 and patient was qualified to palliative treatment.
