Verruca vulgaris of the larynx (VVL) is an extremely rare disease that can be easily misdiagnosed as papillary keratosis, squamous papilloma or verrucous carcinoma, which would have led to needless operation. We experienced a case of VVL in a 66-year-old man with 1-year history of progressive hoarseness. Whitish lesions in both vocal cords were observed by using indirect laryngoscopy and completely removed via microlaryngeal surgery with $CO_2$ laser.

Heterotopic salivary gland tissue (HSGT) or salivary gland choristoma is defined as the histologically normal salivary gland tissue found in organs other than salivary glands. HSGT in middle ear is an extremely rare entity. It is considered as a result of developmental abnormality and may be associated with abnormalities of adjacent structures. A 59-year-old male patient, who suffered from the left side hearing impairment after a head trauma 40 years ago, visited our outpatient clinic. The audiogram showed severe conductive hearing loss on the left side and small soft tissue density filling in the middle ear cavity was observed. Explotympanotomy was done for diagnosis as well as treatment. The stapes was surrounded by yellowish soft tissue and adhered to exposed tympanic segment of the facial nerve. After removing the soft tissue, ossiculoplasty was followed. The final pathological diagnosis was HSGT and the patient is under observation without any complications.

Iophendylate (Pantopaque), an oil-based contrast media, was introduced in 1940s and widely used in myelography, cisternography and ventriculography. Because of its low clearance rate, it caused chronic complications such as arachnoiditis and it was replaced by watersoluble medium after 1990s. However, the remnants are found on imaging tests even several decades later. A 65-year-old man visited with vertigo and sudden hearing loss on his right ear. Temporal bone magnetic resonance imaging conducted and two hyperintense nodules in left internal auditory canal on both T1- and T2-weighted images. Also, computed tomography revealed multiple intracranial hyperdense plaques. Additional history taking confirmed that patient received myelography 40 years ago, and the image findings were consistent with iophendylate.

Ceruminous adenoma is rare neoplasm of external auditory canal (EAC) and can present a diagnostic difficulty because of their varied clinical and histological manifestations. We experienced a case of EAC mass extending to middle ear and mastoid cavity which was first diagnosed as malignancy on frozen biopsy, but confirmed as benign ceruminous adenoma on permanent pathology. Further imaginary evaluations reveal that no other abnormalites were shown except EAC, middle ear, and mastoid cavity. A complete surgical excision via subtotal petrosectomy was done to prevent recurrence. To our knowledge, most of reported ceruminous adenoma cases have been localized to EAC, making this case uncommon. Herein, we present a case of histologically confirmed EAC ceruminous adenoma extending to mastoid and middle ear cavity with brief literature review.
