ABSTRACT
Acquired middle ear cholesteatoma is considered to be formed by retraction of the tympanic membrane. There are rare cases in which the tympanic membrane epidermis extends into the medial surface of the tympanic membrane from the margin of its perforation, namely so-called secondary cholesteatoma. We studied the cases of secondary cholesteatoma clinically. These cases were found in 13 of 419 ears (3.1%) with acquired middle ear cholesteatoma operated on in our hospital from March 2001 to October 2010. The average age of all the cases was 51.5 years old, with a range of 11-65 years. We adopted the canal wall down tympanoplasty procedure with canal reconstruction in all cases. The postoperative hearing improvement rate was 84.6%. There were no cases of recurrence of the cholesteatoma.

We report a case of malignant epiglottic natural killer (NK)/T cell lymphoma. A 33-year-old man seen 1-month period for throat pain was found in endoscopic larynx examination to have inflammation with plaques and redness epiglottic. The 4 month period, right epiglottic inflammation showed progressive necrosis. The diagnosis of malignant lymphoma was confirmed by 3 biopsies. Laryngomicrosurgery specimens histologicalily showed moderate leukocytic infiltration mainly of atypical lymphocytes. Neoplastic cells were UHCL1+, CD3+, L26-, CD79a, and EBER-ISHW. Despite 4 units of DeVIC chemotherapy and regional irradiation, the man died of metastatis 1 year and 9 months after initial treatment. Among malignant laryngeal tumors, malignant epiglottic NK/T cell lymphoma is extremely rare, with only one case reported in the literature.
