Popularized as the “Sister Joseph’s nodule” is the metastatic lesion of the umbilicus. Hitherto, cases had been reported worldwide. Therefore, this article aims to document the patterns of it obtained among an ethnic group in a developing community. Incidentally, a few indigenous doctors suspected the lesions to be of the Sister Joseph nodule type. The epidemiological data included equality of sex and the preponderance of adenocarcinomas.

Metastatic carcinoma of the umbilicus gained prominence when, “during the early days of the Mayo Clinic, Sister Mary Joseph, the superintendent of St. Mary’s Hospital and Dr. William Mayo’s frequent first assistant, imparted this clinical observation to Dr. Mayo after noting a firm nodule of the umbilicus in many patients with intra-abdominal cancer” . Indeed, Sharaki and Abdel-Kader  published on 12 cases and entitled them “the Sister Joseph’s nodule.” Likewise, “Sister Joseph’s nodule” topped the title of the 7 cases published by Brustman and Seltzer , as well as the single case of Bank and Liberman  and also that of Samitz .
Individual cases are noteworthy especially as they centered
on the different primary growth from the skin  and the uterine cervix . Accordingly, deserving of documentation is the author’s series from a developing community.
The findings were made in Nigeria concerning 16 patients of the Ibo/Igbo ethnic group . Moreover, the data came through a histopathology data pool just as was recommended for epidemiological analysis by a Birmingham (UK) group . Doctors serving the populace were encouraged to carry out biopsies, to preserve them in normal-saline and to give adequate clinical details in the Request Forms. The data were analyzed personally.
Of the more recent findings, the tendency is still to dwell on
the Sister Joseph nodule nomenclature. Thus, Palaniappan 
and group saw a case series in which 4 Sister Joseph nodules
came from 4 different viscera, namely, gall bladder, ovary, rectum
and gastrointestinal stroma. The literature came from Morocco
, Taiwan , Greece  and India .
