Abstract: Objective: To demonstrate a unique case report about late and isolated vulvar metastasis of sigmoid adeno-carcinoma with review of
the literature. Material-method: 57 year old postmenopausal patient with prior sigmoid colon cancer was admitted with isolated vulvar mass.
Immunohistochemistry (IHC) and KRAS gen mutation analysis following surgery were performed to discriminate the metastasis from a vulvar
primary malignancy. Further imaging techniques were also performed to exclude additional tumours. Results: Immunohistochemistry (IHC)
and KRAS gene mutation analysis revealed isolated metastasis of the colonic adeno-carcinoma in the vulva. Conclusion: Isolated and late
occurring vulvar metastasis of colonic origin is very unusual. Careful evaluation is mandatory and IHC is useful for such cases.
