Although gastrointestinal involvement by metastatic malignant melanoma is common but primary gastrointestinal (GI) melanoma has been reported in rare cases. In this study we report two cases of primary gastrointestinal malignant melanoma that one of them is a known case of neurofibromatosis type 1(NF1). Both cases showed no evidence of any lesions in skin and eye. Malignant melanoma of GI tract in patient with neurofibroma is reported with hypothesis of a possible relation between two pathologies. Both primary GI melanoma and combination of NF1 with primary GI melanoma are rare entities discussed in this article.

Background and Objective: Failure to thrive (FTT) is a sign that describes a particular problem rather than a diagnosis and explain growth failure or more advanced failure to gain weight appropriately. The aim of this study was to determine the prevalence and type of chromosomal abnormalities in patients presented with FTT.
Materials and Method: One hundred FTT cases with clinical impression of having chromosomal abnormality referred for cytogenetic study during a period of 5 years (2007-2011) with age range from 5 month to 15 years. Chromosomal analysis was carried out for them. The standard protocol for peripheral blood lymphocyte culture was followed by metaphase chromosome preparation and conventional analysis of G-banded chromosomes. All analyses were performed using the SPSS soft ware package, version 18.
Result: Fifteen cases showed karyotypic abnormality. The most common karyotype abnormality was aneuploidy resulted from monosomy of the chromosome X in girls.
Conclusion: Turner syndrome with various forms of chromosomal complement is the most common chromosomal abnormality causing growth failure in girls.
