Nasopalpebral Lipoma-Coloboma syndrome: Clinical, radiological, and histopathological description of a novel sporadic case

Nasopalpebral Lipoma sine Coloboma Syndrome-First Case Report

The nasopalpebral lipoma-coloboma syndrome was described for the first time in 1982. It is an autosomal dominant syndrome with complete penetrance and is characterized by features like congenital symmetric upper eyelid and nasopalpebral lipomas, bilateral symmetric upper and lower eyelid colobomas, broad forehead, widow's peak, abnormal eyebrow pattern, telecanthus, broad nasal bridge, maxillary hypoplasia, and ophthalmological abnormalities. We report a case of a milder variant of the nasopalpebral lipoma-coloboma syndrome that we have termed "nasopalpebral lipoma sine coloboma syndrome." Such a milder variant is not reported hitherto in the literature. We also describe the surgical correction of the deformity in a case that presented in adulthood, with a satisfactory and pleasing aesthetic outcome.

Diagnosis and treatment of upper eyelid lipoma: A case report

Purpose

Presentation of a rare lesion: a case of upper eyelid lipoma,

Observations

A 76-year-old otherwise healthy woman presented with a right upper eyelid swelling. Her medical history was recorded. On ophthalmologic examination a soft, non-ulcerated and not well-circumscribed mass was evident. An ultrasonography examination was carried out showing a hyperechoic non capsulated mass situated between the superior orbital margin and the orbicularis oculi muscle.

Conclusions and Importance

Eyelid lipomas must be differentiated from herniated orbital fat, cystic lesions, tumours, and the lacrimal gland.

A pre-operative differential diagnosis of eyelid lipoma can be done through medical history, ophthalmologic, and ultrasonography examinations. Nevertheless, in case of doubt a magnetic resonance imaging (MRI) should be performed to assess a possible orbital involvement and to plan for the right surgical procedure to be performed.

Exome sequencing identifies a de novo frameshift mutation in the imprinted gene ZDBF2 in a sporadic patient with Nasopalpebral Lipoma-coloboma syndrome

Nasopalpebral lipoma-coloboma syndrome (NPLCS, OMIM%167730) is an uncommon malformation entity with autosomal dominant inheritance characterized by the combination of nasopalpebral lipoma, colobomas in upper and lower eyelids, telecanthus, and maxillary hypoplasia. To date, no genetic defects have been associated with familial or sporadic NPLCS cases and the etiology of the disease remains unknown. In this work, the results of whole exome sequencing in a sporadic NPLCS patient are presented. Exome sequencing identified a de novo heterozygous frameshift dinucleotide insertion c.6245_6246 insTT (p.His2082fs*67) in ZDBF2 (zinc finger, DBF-type containing 2), a gene located at 2q33.3. This variant was absent in parental DNA, in a set of 300 ethnically matched controls, and in public exome variant databases. This is the first genetic variant identified in a NPLCS patient and evidence supporting the pathogenicity of the identified mutation is discussed. © 2016 Wiley Periodicals, Inc.

Congenital upper eyelid coloboma: embryologic, nomenclatorial, nosologic, etiologic, pathogenetic, epidemiologic, clinical, and management perspectives

Purpose:

To review the recent literature and describe the authors’ experience with congenital upper eyelid coloboma.

Methods:

In this review, we will summarize the embryologic and etiopathogenetic bases of congenital upper eyelid coloboma, and study the published clinical reports. We will also attempt to briefly shed some light on the rarer syndromic curiosities associated with upper eyelid coloboma.

Results:

Congenital upper eyelid colobomas are one of the few nontraumatic oculoplastic emergencies that may occasionally present in the first few days of life with a corneal ulcer and may even present with impending perforation. They can present with or without corneopalpebral adhesions, may be isolated findings or a part of a larger spectrum of congenital anomalies as in the case of Fraser syndrome or Goldenhar syndrome, or could be associated with other rare curiosities that could challenge the clinician with a huge diagnostic dilemma.

Conclusions:

Existing literature dealing with congenital colobomas of the upper eyelid is fraught with nosologic problems, confusing etiologies, and overlapping clinical features. We attempted to clarify the salient clinical features, outline the management principles, and until a time in the not-so-distant future where advances in molecular genetic testing would help redefine the etiology and the diverse clinical spectrum of genetic diseases associated with upper eyelid colobomas, we propose a simplified classification scheme based on the relation of the coloboma to the cornea, the presence or absence of systemic features, and all the syndromic and nonsyndromic associations of congenital coloboma of the upper eyelid known today.

In this review, the authors will describe the pathogenesis of upper eyelid coloboma, suggest a new simplified classification system, describe the clinical picture in detail, clarify the various syndromic associations of upper eyelid coloboma, and lay out the basic surgical principles of management.

Syndromic lipomatosis of the head and neck: a review of the literature

INTRODUCTION

Patients with syndromic causes of lipomatosis of the head and neck, although rare, often present late in the course of the disease in a myriad of ways, including concomitant airway obstruction, severe functional limitations, and/or significant cosmetic defects. The goal of this report was to review the literature and present a concise overview of the major syndromes causing lipomatosis of the head and neck.

METHODS

A literature search was performed to gather information on syndromic lipomatosis of the head and neck region. PubMed was searched for the following conditions: Familial multiple lipomatosis (FML), multiple symmetrical lipomatosis (MSL), congenital infiltrating lipomatosis of the face (CIL-F), and Nasopalpebral lipoma-coloboma syndrome (NLCS). Data gathered included results of surgical cases of the head and neck region.

RESULTS

A total of 48 reports comprising 172 cases of syndromic lipomatosis of the head and neck region were deemed eligible for review. Eighty-five percent of patients were male with an average age of 35 years. Seventy-four percent of cases appeared in the neck region, whereas 23 % presented in the face and scalp. 89 % of cases were treated with surgical excision, with 11 % of cases treated with liposuction. The most common complications were hematoma and seroma in MSL, recurrence in FML, neuropraxia in CIL-F, and mild telecanthus in NLCS.

CONCLUSIONS

Syndromic causes of lipomatosis are generally benign in nature but difficult to control long term. Because these conditions include frequent recurrence and subsequent difficulty in clearing the disease, the authors advocate early and aggressive surgical excision of syndromic lipomatosis.
