Cutaneous metastases from carcinoma of gall bladder.

Cutaneous metastases from internal carcinoma are relatively rare. Metastasis to extremities is still rarer. We report a case of cutaneous metastasis from carcinoma of gall bladder in a 40-year female presenting as a mass in the left lower thigh. The mass was there for four months duration which was progressively growing in size and painful. Mass was 5 x 7 cm2 in size, mobile, hard and tender. The skin overlying the swelling was eroded with ulcer formation showing sloping edge and slough in the floor. Fine needle aspiration cytology and excisional biopsy revealed a metastatic adenocarcinoma. Cutaneous metastases have been regarded as a bad prognostic indicator.
