Orta kulak mukozasının primer malign melanomu: Olgu sunumu

Orta kulak ve mastoid kavite mukozasının malign melanoma bağlı primer tutulumu nadirdir. Sol ku- lakta ağrı, dolgunluk ve işitme kaybı yakınmalarıy- la başvuran 81 yaşındaki kadın hastanın otosko- pik muayenesinde mor renkli, vasküler görünüm- de kitlenin sol dış kulak yolunu tıkadığı görüldü. Bilgisayarlı tomografide yumuşak doku dansite- sindeki kitlenin orta kulak ve mastoid kaviteyi dol- durduğu, mastoid korteksi erode ederek dış kulak yolunun medial ve orta kısımlarını invaze ettiği görüldü. Kitleden alınan biyopsi sonucu malign melanom olarak bildirildi. Hastaya subtotal tempo- ral kemik rezeksiyonuna ek olarak radikal boyun diseksiyonu uygulandı ve ameliyat sonrası dö- nemde dakarbazin verildi. Temporal kemikten kaynaklanan tümörlerin ayırıcı tanısında malign melanomdan şüphelenmek erken tanıya olanak sağlamaktadır

Primary malignant melanoma of the middle ear mucosa: a case report

Primary involvement of the middle ear and mastoid mucosa by malignant melanoma MM has been rarely reported. We report an 81-year-old Caucasian woman presenting with otalgia, left-sided aural fullness, and hearing loss. Otoscopic examination revealed a purple coloured polyp that appeared to be vascular and occu- py left external auditory canal EAC . The computed tomography scanning showed a mass in soft tissue density, filling the tympanic and the mastoid cavities, eroding the mastoid cortex, and invading medial and Central parts of EAC. A biopsy was performed with the diagnosis of MM. The patient undervvent subtotal tem- poral bone resection with radical neck dissection.Dacarbazine was given postoperatively. The case pre- sented herein emphasizes the need to be aware that MMs can arise in the middle ear and mastoid cavity. An index of suspicion in the differential diagnosis of tem- poral bone tumours is necessary for early recognition.
