Zusammenfassung
Bindehauttumoren betreffen in Diagnostik und Therapie alle Bereiche der augenärztlichen
Praxis. Das beginnt mit der klinischen Kontrolle von Bindehautnävi und anderen benignen
Tumoren, der Einschätzung von entzündlichen Pseudotumoren und ihrer Abgrenzung zu
Präkanzerosen oder vernarbenden Erkrankungen und mündet in der hochspezialisierten
und interdisziplinären Führung onkologischer Patienten mit Lymphomen, hochmalignen
Melanomen oder invasiven Plattenepithelkarzinomen.
Abstract
The aim of this paper is to give an overview of different benign and malignant epibulbar
tumors. Categories can be made of the age of manifestation (paediatric tumors versus
tumors of adults), the originating cell types (squamous cell tumors, melanocytic tumors,
lymphomas or germ cell tumors) or genesis (proliferative, infectious or degenerating
tumors). Most epibulbar tumors show lesions on the conjunctiva or the cornea. These
can be flesh coloured or pigmented efflorescences with leucoplakias or hyperkeratosis.
Especially malignant tumors show atypical growth of blood vessels, are often prominent
and can have ulcerations or bleeding. In case of tumor growth, change in pigmentations
or atypical bleedings a malign tumor can be suspected. The diagnosis should be confirmed
using histopathological evaluation after an incisional or excisional biopsy. Molecular
pathologic techniques extend the diagnostic tools and have an implication on the therapy
of metastatic tumors.
Therapeutic options of the malignant tumors (apart from lymphomas) are chirurgical
excision preferably with a no touch technique and afterwards an adjuvant therapy consisting
of radiation or cryotherapy. A topical chemotherapy with Mitomycin C, 5-Fluorouracil
or Interferon α2b can be effective to reduce persisting precancerosis and reduce recurrences.
In case of a suspected malignant tumor it is advisable to refer the patient to an
ophthalmo-oncologic center to plan and ensure interdisciplinary therapy.
