ABSTRACT

The metastasis of a visceral malignancy to the umbilicus is known as "Sister Mary Joseph's nodule". It is a rare clinical sign indicating advanced, metastasizing intraabdominal cancer. We report a 50-year-old man who developed metastatic skin cancer in the form of semicircular indurated plaque on top of which was a firm mobile rounded nodule at the umbilical area. Histopathological examination demonstrated diastase-resistant periodic acid-Schiff and mucicarmine positive signet ring cells, suggesting gastric carcinoma. Immunohistochemical staining showed that these cells were positive for cytokeratins and epithelial membrane antigen, suggesting epithelial origin.

ABSTRACT

OBJECTIVE: To uncover the frequency and the spectrum of NPHS2 mutations in Egyptian children with non familial steroid-resistant nephrotic syndrome (SRNS). METHODS: Sixteen patients were screened by PCR-single-strand conformation polymorphism analysis of NPHS2 gene followed by direct sequencing. RESULTS: NPHS2 mutations were evident in four patients (25%) who were bearing four novel mutations including two frame shift mutations (R238fs and P45fs) and two missense mutations (I136L and F216Y). There were no phenotypic or histological characteristics of patients bearing NPHS2 mutations, apart from the earlier onset of the disease, compared to those who were not bearing mutations. CONCLUSION: NPHS2 mutations are prevalent in Egyptian children with non-familial SRNS and this may in part explain the less favorable prognosis reported in these patients.
