Nasopalpebral lipoma-coloboma syndrome

Nasopalpebral lipoma-coloboma syndrome (also known as Penchaszadeh syndrome) is an extremely rare congenital disorder characterized by the combination of congenital upper eyelid colobomas (notch-like defects in the eyelids) and symmetrical lipomas (benign fatty growths) affecting the nose and eyelids. The condition is present at birth and primarily affects structures of the face, particularly the eyes and nose. Key clinical features include bilateral upper eyelid colobomas, nasopalpebral lipomas that may extend from the inner corners of the eyes across the bridge of the nose, telecanthus (widely spaced inner corners of the eyes), and a broad nasal bridge. Some patients may also have additional findings such as sparse or absent eyebrows medially, and mild facial dysmorphism. Vision may be affected depending on the severity of the eyelid colobomas, which can lead to corneal exposure and associated complications if left untreated. The syndrome was first described by Penchaszadeh in 1982. It appears to follow an autosomal dominant inheritance pattern, though the underlying genetic cause has not been fully elucidated. The condition has been reported in a very small number of families worldwide. Treatment is primarily surgical and supportive, focusing on repair of the eyelid colobomas to protect the cornea and preserve vision, as well as cosmetic removal of the lipomas if desired. Early ophthalmologic evaluation is important to prevent corneal damage. With appropriate surgical management, the prognosis is generally favorable, as the condition does not typically involve systemic or life-threatening complications.
