Aggressive papillary tumors of the middle ear constitute a small percent of adenomatous middle ear tumors. Patients usually present with long-lasting tinnitus, hearing loss, and vertigo and occasionally facial paralysis. Computed tomography findings predominantly suggest bone invasion. Thus, it is commonly misdiagnosed with chronic otitis media with a cholesteatoma. A 72-year-old man presented with chronic ear pain and ear drainage. The patient had a 63 decibels (dB) mixed-type hearing loss and a mass lesion at the temporal bone high resolution computed tomography. Explorative tympanotomy revealed a tumor with thick mucoid secretion and no bone erosion, for which an incisional biopsy revealed an adenoma. Radical modified mastoidectomy was performed and the definite pathology result was compatible with an aggressive papillary tumor. The patient was free of disease at six months of follow-up.
Angiomyolipoma is a benign tumor consisting of vascular structures, smooth muscle and adipose tissue. It is most commonly found in the kidney and more infrequently in the liver, lung, heart, intestines, nasal cavity, oral cavity and ear. Cutaneous angiomyolipomas are very rare and show some differences with non-cutaneous angiomyolipomas, these are mostly located in the distal extremities and due to trauma, HMB-45 antibody negativity and appear more frequently in men.
All cases except one presented until today were observed not to have cellular atypia; thus, cutaneous angiomyolipomas are considered not to perform malign transformation. It is thought that total excision of the mass is adequate in treatment of cutaneous angiomyolipoma.
Our case applied to our clinic with a left preauricular mass which was thought to be a parotid mass after initial physical examination. After magnetic resonance imaging (MRI) scan was performed, it was seen that the mass did not originate from parotid gland After the FNAC resulted non-diagnostic, the mass was excised. Pathological examination revealed "angiomyolipoma" diagnosis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
