Situs inversus in a patient with nevoid basal cell carcinoma syndrome: a histogenetic relationship?
(65/106)
Nevoid basal cell carcinoma syndrome (NBCCS) is an uncommon autosomal dominant inherited disorder with high penetrance and variable expressivity. It affects multiple organ systems, including the stomatological, skeletal, skin, eye, reproductive, and central nervous systems. It is caused by mutations in the patched tumor suppressor gene, PTCHI, located in the 9q22.3-q31 chromosome. To our knowledge, this is the first report of a patient with unusual radiological features, i. e. dextrocardia and situs inversus totalis, in conjunction with common features including multiple keratocystic odontogenic tumors, bifid ribs, palmar and plantar pits, bridging of the sella turcica and calcification of the falx cerebri. We examined whether these genetic conditions were associated, as both involve ciliary dysfunction. (+info)

Gorlin syndrome is an autosomal dominantly inherited disorder that results in numerous basal cell carcinomas as well as a number of other facial and skeletal findings. We present a patient with many classic features and review some of the treatment options available for these patients. (+info)

Gorlin-Goltz syndrome--a medical condition requiring a multidisciplinary approach.
(71/106)
Gorlin-Goltz syndrome is a rare genetic condition showing a variable expressiveness. It is inherited in a dominant autosomal way. The strongest characteristic of the disease includes multiple basal cell carcinomas, jaw cysts, palmar and plantar pits, skeletal abnormalities and other developmental defects. Owing to the fact that the condition tends to be a multisystemic disorder, familiarity of various medical specialists with its manifestations may reduce the time necessary for providing a diagnosis. It will also enable them to apply adequate methods of treatment and secondary prevention. In this study, we present symptoms of the disease, its diagnostic methods and currently used treatments. We searched 2 scientific databases: Medline (EBSCO) and Science Direct, for the years 1996 to 2011. In our search of abstracts, key words included nevoid basal cell carcinoma syndrome and Gorlin-Goltz syndrome. We examined 287 studies from Medline and 80 from Science Direct, all published in English. Finally, we decided to use 60 papers, including clinical cases and literature reviews. Patients with Gorlin-Goltz syndrome need particular multidisciplinary medical care. Knowledge of multiple and difficult to diagnose symptoms of the syndrome among professionals of various medical specialties is crucial. The consequences of the disease pose a threat to the health and life of patients. Therefore, an early diagnosis creates an opportunity for effective prevention and treatment of the disorder. Prevention is better than cure. (+info)
