Mucinous Carcinoma of the Skin: A Case Report.

Unlabelled: Primary mucinous carcinoma of the skin is a rare malignant neoplasm showing predilection to the periorbital region. These tumours are indolent and low-grade, with a tendency for local, sometimes multiple, recurrences. Distinguishing between these primary neoplasms and the more frequent metastatic mucinous deposits on the skin from primaries in the breast and gastrointestinal tract constitutes a diagnostic dilemma. In this case report, we have put forth the findings of a 70-year-old male who presented with a slow-growing periorbital swelling and was subsequently diagnosed with mucinous adenocarcinoma. An extensive workup in search of another primary tumour failed to show a primary malignancy elsewhere and the diagnosis of primary mucinous adenocarcinoma of the skin was rendered.
