Cutaneous metastases from signet cell carcinoma of the gut: A report of two cases

Abstract

Cutaneous metastasis from visceral tumors is a rare entity with a reported incidence between 0.3% and 9.8%. These usually occur late in the course of the disease; the average time interval between the diagnosis of malignancy and presentation of cutaneous metastases has been reported to be 33 months. In rare instances (in about 0.8%–1.3% of patients), cutaneous metastases may be a pointer to an underlying undiagnosed malignancy. We report two patients presenting to us with soft, nodular, cutaneous lesions, which was the manifestation of metastatic signet cell carcinoma arising from the gut. We report these cases owing to their rarity.
