Primary mucinous carcinoma of the vulva with signet ring cells deriving from the cloaca

Vulvar neoplasias are rarely encountered lesions at female genital tract, regardless if they are primary or metastatic. Presence of signet ring cells in a tumour at female genito-urinary tract is highly suggestive of a metastatic lesion particularly from a gastrointestinal tumour. Here the authors present a case of vulvar carcinoma with signet ring cells with an undetermined primary site possibly originating from embryonic cloaca.
