title: Cutaneous Metastasis from Signet-ring Gastric Adenocarcinoma in a Carcinoma En Cuirasse Pattern: An Unusual Clinical-diagnostic Sequence.
abstract: Cutaneous metastasis (CM) of gastric adenocarcinoma (ADC) is rare and usually presents late in the course of the disease. We report a rare case of carcinoma en cuirasse (CEC) pattern of CM secondary to gastric malignancy in a 55-year-old male patient-the interesting part being that CM was the first-presenting sign, which on further histopathological and immunohistochemical evaluation led to the diagnosis of hidden gastric carcinoma. The finding of signet ring cells (SRCs) on cutaneous biopsy further added a differential of the rare possibility of primary cutaneous tumors.
