BACKGROUND Growth patterns of patients with Noonan syndrome (NS) were established before the involved genes were identified. OBJECTIVE The goal of this study was to compare growth parameters according to genotype in patients with NS. SUBJECTS AND METHODS The study population included 420 patients (176 females and 244 males) harboring mutations in the PTPN11, SOS1, RAF1, or KRAS genes. NS-as...
LEOPARD syndrome (LS, OMIM 151100) is a rare multiple congenital anomalies condition, mainly characterized by skin, facial and cardiac anomalies. LEOPARD is an acronym for the major features of this disorder, including multiple Lentigines, ECG conduction abnormalities, Ocular hypertelorism, Pulmonic stenosis, Abnormal genitalia, Retardation of growth, and sensorineural Deafness. About 200 patie...
Background Limited information exists between the associations of diabetes mellitus (DM) and solar lentigo (SL); a benign, common skin lesion characterized by hyperpigmented macules. Methods This study was conducted on 90 patients diagnosed with DM and their age and sex matched controls who were referred to the Departments of Endocrinology at Babol University of Medical Science in Northern of...
Pigmented spots in the skin and mucosa (lentigines) can be found in various diseases called familial lentiginosis syndromes; Peutz-Jeghers syndrome (PJS) is one of them. It is characterized by the association of mucocutaneous melanin pigmentation and hamartomatous gastrointestinal polyps. Patients with PJS are at increased risk of intussusception and cancer development (gastrointestinal and non...
Quality-switched (q-switched) laser systems are the gold standard for the treatment of benign pigmented lesions and tattoo removal. A frequently used system is the q-switched ruby laser that emits monochromatic light at the wavelength of 694 nm. This system is used for the removal of age spots (senile lentigines), seborrhoeic keratosis, tattoos, and other dyschromatoses. The increasing need for...
Agminated nevus is a cluster group of melanocytic nevi confined to a localized area of the body. There are many pigmented lesions described in the literature as agminated, such as blue nevi, multiple lentigines and Spitz nevi, but only a few cases of congenital agminated melanocytic nevi have been described. We report a case of a male child who presented with congenital agminated nevi, emphasiz...
The LEOPARD syndrome is an exceptional autosomal dominant genetic disease with a missense mutation of the PTPN11 gene in more than 90% of the cases. The principal clinical manifestations include extensive lentiginosis, heart conduction abnormalities, hypertrophic obstructive cardiomyopathy, ocular hypertelorism, pulmonary stenosis, genital anomalies, mental retardation, growth retardation and d...
