The cutaneous manifestations of gastrointestinal malignancy

The skin is often the herald of an underlying systemic illness, and gastrointestinal malignancies can present in numerous ways in the skin. Paraneoplastic phenomenon, such as acanthosis nigricans and tripe palm, may be the first indicator of a gastrointestinal malignancy.

Inflammatory systemic conditions such as dermatomyositis and multicentric reticulohistiocytosis can be associated with underlying malignancy.
