Hypomelanosis of Ito is a neurocutaneous phenotype comprising pigmentary anomalies, neurological defects, structural malformations, and chromosomal abnormalities. It has been described as a distinct multisystem birth defect or, more specifically, as a neurocutaneous syndrome. The main purpose of this study is to provide evidence that this disorder does not exist as a syndrome. Rather, it is a causally nonspecific pigmentary disorder caused by genetic mosaicism.
UNLABELLED: Most cystic lesions of the pancreas are pseudocysts caused by acute or chronic pancreatitis. Congenital cysts are rare and may occur in congenital syndromes like von Hippel-Lindau syndrome. Cystic tumors of the pancreas may be difficult to distinguish clinically; however, because of their malignant potential, in particular in cases of mucinous types, diagnostic verification is crucial. Hence, in all cases of cystic lesions of the pancreas, which are not a sequela of an etiological confirmed acute or chronic pancreatitis, a cystic neoplasm must be ruled out. Differential diagnosis may be difficult even with ultrasonography, computertomography, endoscopic retrograde cholangiopancreatography and serum analyses; endoscopic ultrasound, magnetic resonance tomography and analysis of the cyst content may be of particular value. The therapeutic approach for pseudocysts is now well established and guided by symptoms and complications. If a cystic neoplasm is suspected, surgical resection of the complete lesion is warranted. CONCLUSION: The most important differential diagnosis in all cystic lesions of the pancreas with atypical presentation includes a cystic neoplasm. Therefore complete resection is indicated whenever the suspicion cannot be ruled out.
