Abstract
Lipomas are common benign tumors of mature adipose tissue, enclosed by thin fibrous capsules. They can occur on any part of the body; however, peritoneal lipoma is extremely rare. We encountered a case of a 75-year-old man presenting with intermittent abdominal pain, who had undergone right hemicolectomy due to colon cancer. Abdominal computerized tomography showed a well-defined heterogenous fatty mass measuring 4.5 × 3.5 cm in size, suggesting fat necrosis located in the abdominal wall. Laparotomy showed a very large soft mass of peritoneum. Pathologically, the tumor was diagnosed as lipoma containing fat necrosis located in parietal peritoneum not fixed to any organs, but with small bowel adhesion. Due to its rare etiologic origin and obscure cause of development, we report on a case of lipoma of parietal peritoneum causing abdominal pain.

Abstract
Adipose and myxoid tumors in children are an unusual and challenging group of neoplasms that have some unique aspects in contrast to these tumors in adults. Less than 10% of soft tissue neoplasms in the 1st 2 decades of life have an adipose phenotype and most are benign. The most common are various types of lipoma and lipoblastoma. Liposarcoma in young patients is rare and has a distinctive distribution of histologic subtypes, including classic myxoid liposarcoma, and unusual variants, such as pleomorphic-myxoid liposarcoma. Pathologic examination enhanced by adjunct techniques, such as immunohistochemistry and cytogenetic or molecular genetic studies, is useful for classification of difficult cases. Myxoid tumors can overlap with adipose tumors and are included in this review because of the morphologic similarities and importance of diagnostic accuracy. This article reviews the clinicopathologic features of adipose and myxoid tumors with an emphasis on the unique aspects of these neoplasms in children and adolescents and the differential diagnosis.

Abstract
The PTEN hamartoma tumor syndromes (PHTS) are a collection of rare clinical syndromes characterized by germline mutations of the tumor suppressor PTEN. These syndromes are driven by cellular overgrowth, leading to benign hamartomas in virtually any organ. Cowden syndrome (CS), the prototypic PHTS syndrome, is associated with increased susceptibility to breast, thyroid, and endometrial cancer. PTEN is located on chromosome 10q22-23 and negatively regulates the prosurvival PI3K/Akt/mTOR pathway through its lipid phosphatase activity. Loss of PTEN activates this pathway and leads to increased cellular growth, migration, proliferation, and survival. Clinical management of patients with PHTS, particularly those with CS, should include early and frequent screening, surveillance, and preventive care for associated malignancies. Concomitant with improved understanding of the biology of PTEN and the PI3K/Akt/mTOR pathway, inhibitors of this pathway are being developed as anticancer agents. These medications could have applications for patients with PHTS, for whom no medical options currently exist.

Abstract
Bannayan-Riley-Ruvalcaba syndrome (BRRS) is characterised by macrocephaly, intestinal hamartomatous polyps, lipomas, pigmented maculae of the glans penis, developmental delay and mental retardation. The syndrome follows an autosomal dominant pattern of inheritance. In 1997 reports on two BRRS patients with a deletion at 10q23.2-q24.1 were published. In the same year, the first two families with BRRS and a mutation of the PTEN gene were reported. Mutations in the PTEN gene have also been demonstrated in patients with Cowden syndrome (CS), which shows partial clinical overlap with BRRS, and in families with cases both of BRRS and CS. PTEN mutation positive BRRS and CS are likely to be different phenotypic presentations of the same syndrome. If BRRS and CS are one single condition, the question arises whether patients with BRRS should be screened for malignant tumours, since patients with Cowden syndrome have an increased risk of breast, endometrial, thyroid and renal cancer. We present two isolated cases and one family and confirm that BRRS and CS are allelic. Furthermore, we review the PTEN mutation positive BRRS cases, to further delineate the phenotype and to compare the cases with a genomic deletion with the cases with a point mutation. We recommend offering BRRS cases with a mutation in PTEN the same surveillance protocol for (malignant) tumours as is currently recommended for CS. In addition, we propose a yearly haemoglobin test from early infancy for the early detection of intestinal hamartomas, which are likely to give severe complications, especially in BRRS cases.

Abstract
Cowden syndrome (CS) and Bannayan-Zonana syndrome (BZS) are two inherited hamartoma syndromes characterized by distinct phenotypic features. Mutations in the PTEN gene have been identified in patients with CS and BZS, suggesting the presence of a common genetic basis. We describe a single kindred with individuals manifesting both CS and BZS phenotypes (CS/BZS overlap family) in which we have identified a novel mutation in PTEN by DNA sequencing. We have confirmed these results by means of restriction enzyme analysis. The presence of individuals with CS and BZS within the same family, and moreover the identification of identical PTEN gene mutations in these individuals, suggest that these two syndromes represent different phenotypic expressions of one disease. Furthermore, these findings imply that, like patients with CS, individuals with BZS should be monitored for the onset of malignancy.

Abstract
Single café-au-lait macules (CALMs) are common in the pediatric population and in most children represent a normal finding. It is important to recognize whether the presence of multiple CALMs in a particular patient is normal or indicates an association with a multisystem disorder. This article addresses issues concerning the prevalence, genetics, and natural history of CALMs in the general population and reviews disorders in which CALMs are present as a characteristic trait.

Abstract
BACKGROUND Bannayan-Zonana syndrome is a rare hamartomatous disorder, characterized by macrocephaly, multiple lipomas, and hemangiomas. Inheritance is by autosomal dominant transmission with few reported sporadic cases. Male predominance is also reported. METHODS We describe a patient who presented with multiple subcutaneous lipomas, mild macrocephaly, and an extradural spinal hemangioma. Other affected family members and 24 other previously reported cases are discussed. RESULTS Spinal hemangiomas have not been described previously with this syndrome. The patient also had a "malignant bone tumor" removed from his humerus 20 years ago. Two of the patient's siblings also had lymphoma, which is an unusual accompaniment not reported previously. Only the male members in the family showed multiple subcutaneous lipomas. CONCLUSION Some patients with Bannayan-Zonana syndrome may have hamartomatous lesions producing cord compression or intracerebral hemorrhage, or they may rarely have other malignant tumors; therefore it is important that neurosurgeons are aware of the entity. The early diagnosis of BZS is also important for genetic counseling.

Abstract
Since its first description few cases of the rare association of macrocephaly with multiple soft tissue and visceral hamartomas (Bannayan-Zonana syndrome) have been reported. In this paper we report a case of a 7 year old child in whom lipomas of the abdomen and right flank have been treated with liposuction. We could find no previous evidence that this surgical technique has been used in the treatment of this syndrome.

Abstract
We describe 2 unrelated patients, a boy and a girl, with an overgrowth syndrome and the following common characteristics: macrocrania, obesity, ocular abnormalities (retinal coloboma and nystagmus), downward slant of palpebral fissures, mental retardation, and delayed bone maturation. Both cases are of sporadic occurrence with no consanguinity between the parents. We suggest that this syndrome is due to a new autosomal dominant mutation and propose to designate it with the acronym of "MOMO syndrome" (Macrosomia, Obesity, Macrocrania, Ocular anomalities.

Abstract
Children with Sotos syndrome have growth acceleration, macrocephaly, acromegaloid features and delay in neuropsychomotor development during infancy. Syndrome delineation and differential diagnosis are based on evaluation of phenotypic characteristics and evolutive history of the patients. Seven patients with this syndrome are reported, and the relative occurrence of the phenotypic characteristics present in 198 reported cases are reviewed. Motor difficulties present in those patients during early infancy are responsible for the poor performance on IQ tests. Oriented stimulation should be encouraged in order to help the affected children to overcome their initial difficulties and to achieve normal scholarity and life performance.
