ABSTRACT
In the English literature, there have only been seven reports of metastasis from cancer of the gallbladder to the skin. This is the report of a 75-year-old woman who developed cutaneous metastasis from an adenocarcinoma of the gallbladder which was confirmed histologically. We report the uncommon metastatic potential of gallbladder carcinoma to the skin.

Symptomatic colonic lipomas, although unusual, continue to present difficulties in the preoperative differential diagnosis between malignant and benign colonic neoplasm. Although new imaging techniques are available, they are frequently diagnosed at laparotomy, and definitive histology is required. Local excision is adequate treatment, but segmental excision may be necessary when there is doubt about the diagnosis, or when a complication occurs.

The clinical and pathological features of two cases of retrorectal cyst-hamartoma are presented. Both lesions were characterized by the presence of cysts lined by mucus-producing, ciliated and transitional epithelium. The anatomical and histological findings in our cases of retrorectal cyst-hamartoma are in favor of an embryologic origin from remnants of the postanal gut. The differential diagnosis includes teratomas, dermoid cysts, duplication cysts of the rectum, anal gland cysts, and anal gland carcinomas. To avoid complications, particularly malignant transformation, early complete excision is recommended.
