Conclusion: Medulloepithelioma in a child can present as a clinical triad of leukocoria, lens changes, and a white cystic ciliary body mass. [ojoonline.org]

To date, there has been no report of a child with ectopia lentis as the only presentation of an intraocular tumor. We present 2 children with malignant medulloepitheliomas who presented in this fashion. [ncbi.nlm.nih.gov]

Typical presentation: Patients typically present with a clear to flesh-toned mass arising from the ciliary body. [morancore.utah.edu]

  If CSF is obtained within 10 days of the operation, detection of tumor cells within the spinal fluid is possibly related to the surgical procedure. [cancer.gov]

• Aspiration

  Transscleral fine needle aspiration was performed. Aspirates were rich and composed of two distinctive populations of cells. The first consisted of epithelioid large cohesive cells with rare rosettes. [ncbi.nlm.nih.gov]

  PURPOSE: To report a case of an adult with a ciliary body mass diagnosed as a medulloepithelioma by fine-needle aspiration, confirmed by tissue biopsy, and successfully treated with brachytherapy. DESIGN: Interventional case report. [uthscsa.influuent.utsystem.edu]

  Definitive diagnosis and eye-conserving therapy is possible with fine-needle aspiration biopsy. [pubmed.ncbi.nlm.nih.gov]

• Visual Impairment

  Symptoms: The usual presenting symptoms of medulloepithelioma are a red eye, change in color of the iris, visible mass in the iris, and visual impairment. [medigoo.com]

  As a result, they tend not to impair visual acuity except in the rare instance in which they cause cataract progression. [atlasgeneticsoncology.org]

• Confusion

  Medulloepithelioma, often confused with less aggressive PNETs, can mimic intrinsic brainstem glioma, responds poorly to treatment, and is prone to CNS dissemination at the time of tumor progression. [ncbi.nlm.nih.gov]

  It should not be confused with an even rarer tumor sometimes encountered within the brain; see medulloepithelioma of the brain. [radiopaedia.org]

  It is emphasised that with such confusing clinical presentations, histopathological diagnosis should not be made on the basis of a small biopsy from a part of the tumor only. [ijo.in]

Diagnosis, Workup and Treatment The leading differential diagnoses included retinoblastoma, medulloepithelioma and juvenile xanthogranuloma. [reviewofophthalmology.com]

Treatment with iodine-125 brachytherapy (4,648 cGy) was employed to debulk the mass before eyewall resection. [ncbi.nlm.nih.gov]

All six patients that were managed by local resection (iridocyclectomy) as primary treatment developed tumor recurrence, requiring additional treatment of enucleation in four, exenteration in one, and cryotherapy in one patient. [5] Intraocular medulloepithelioma [ojoonline.org]

On the other hand, medulloepitheliomas occurring in the eye or the orbit generally benefit from a gross-total resection and may present a good prognosis. [ncbi.nlm.nih.gov]

Treatment and prognosis Medullary epithelioma carries dismal prognosis with a median survival of 5 months. [radiopaedia.org]

Disease Medulloepithelioma Etiology Medulloepithelioma is a tumor that arises from the epithelium of the medullary tube, most often the ciliary body. [atlasgeneticsoncology.org]

Iris cysts ICD-9 364.60 ICD-10 H21.302 Etiology An iris cyst is an epithelial-lined space that involves a layer of the iris. A primary iris cyst does not have a recognizable etiology. [eyewiki.aao.org]

However, non-neoplasmic etiologies must be ruled out. The presence of the ciliary mass may be secondary to chronic inflammatory lesion. Granuloma forming infection like ocular toxocariasis must be considered. [egms.de]

Epidemiology: Medulloepithelioma is a rare intraocular cancer, so rare in fact, that incidence is difficult to quantify. 75-90% of intraocular medulloepitheliomas present in the first decade of life, however, there are reported cases of new medulloepitheliomas [morancore.utah.edu]

Epithelium from stromal cysts contains goblet cells. [3] Pathophysiology The pathogenesis of primary iris cysts is not entirely understood, and proposed mechanisms in the literature are controversial. [eyewiki.aao.org]

Treatment A total resection to completely remove the tumor is usually necessary to prevent it from spreading further. Radiotherapy is used may also be necessary in some cases, in order to shrink the tumor and prevent it from growing. [bookinghealth.com]

However, the long gap in follow-up prevented a more timely diagnosis because it delayed further investigations, such as ultrasound biomicroscopy, computed tomography, or magnetic resonance imaging. 2 In cases with an idiopathic diagnosis, avoiding premature [healio.com]

We have shown that a chemotherapy regimen consisting of systemic vincristine, carboplatin and etoposide appears to have been a safe adjuvant treatment following enucleation and may help to prevent recurrence and metastases. [nature.com]

Early diagonosis and treatment led to regression, allowing enucleation and preventing further extrascleal spread. [medcraveonline.com]

Adjuvant radio and chemotherapy is often indicated.[14] Prevention There are no primary preventive measures available for medulloepithelioma. References ↑ Chakrabarti I, Majumdar K, Giri A (2012). [wikidoc.org]
