Cutaneous lipomas are rare in children, but these tumors can occur as part of the inherited disease Bannayan-Zonana syndrome.Lipomas are usually relatively small with diameters of about 1–3 cm, but in rare cases they can grow over several years into "giant lipomas" that are 10–20 cm across and weigh up to 4–5 kg. Other animals
Lipomas occur in many animals, but are most common in older dogs, particularly older Labrador Retrievers, Doberman Pinschers, and Miniature Schnauzers. Overweight female dogs are especially prone to developing these tumors, and most older or overweight dogs have at least one lipoma. In dogs, lipomas usually occur in the trunk or upper limbs. They are also found less commonly in cattle and horses, and rarely in cats and pigs. However, a pedunculated lipoma can cause entrapment and torsion of the intestine in horses, causing necrosis, colic, and possibly death. The intestine becomes twisted around the stalk of the lipoma and loses blood supply. References

Feingold syndrome (also called oculodigitoesophagoduodenal syndrome) is a rare autosomal dominant hereditary disorder. It is named after Murray Feingold, an American physician who first described the syndrome in 1975. Until 2003, at least 79 patients have been reported worldwide. Presentation
Feingold syndrome is marked by various combinations of microcephaly, limb malformations, esophageal and duodenal atresias. Cognition is affected, and ranges from below-average IQ to mild intellectual disability. Genetics
Feingold syndrome is caused by mutations in the neuroblastoma-derived V-myc avian myelocytomatosis viral-related oncogene (MYCN) which is located on the short arm of chromosome 2 (2p24.1). This syndrome has also been linked to microdeletions in the MIR17HG locus which encodes a micro RNA cluster known as miR-17/92. Diagnosis
The diagnosis is based on the following clinical findings:
microcephaly
clinodactyly and shortness of index and little fingers
syndactyly of 2nd & 3rd and 4th & 5th toe
short palpebral fissures
esophageal and/or duodenal atresia

Treatment
There is no known treatment for the disorder, but surgery for malformations, special education, and treatment of hearing loss are important. References
