Background and Objectives : Vocal polyps are caused by inflammation induced by stress or irritation. Many patients with vocal polyps complain voice discomfort. For vocal polyps, surgery such as laryngeal microsurgery has been the mainstay of management. We analyzed the clinical features of vocal polyps, and how the size and location of vocal polyps affect the outcomes of surgery. Methods : We retrospectively reviewed 42 patients from March 2014 to December 2015, who were diagnosed as unilateral single vocal polyp. When we operated on a vocal polyp with laryngeal microscopy, we measured their size and location. The quality of voice was evaluated by GRABS scale, jitter, shimmer, NHR (noise to harmonic ratio), MPT (maximum phonation time), and VHI (voice handicap index) before operation and 4 weeks after operation. Results : When we divided the patients into large-sized vocal polyp group (the longest length >3 mm) and small-sized vocal polyp group (the longest length ${\leq}3mm$), all parameter differences tend to be greater at large sized vocal polyp. However, these differences were not statistically significant (p>0.05). When we divided into two groups depending on the volume of vocal polyp, no distinct tendency was found. When we compared the location (anterior, mid and posterior) of vocal polyp with the improvement of voice quality, more change was found at mid portion vocal polyp, except the difference of VHI. However, these differences were also not statistically significant (p>0.05). Conclusion : All parameter differences tend to be greater at large vocal polyp and polyp of the mid location.

Progressive transformation of germinal centers(PTGC) is a rare benign lymph node enlargement characterized by chronic lymphadenopathy and the presence of germinal centers with fused and expanded mantles within a lymph node that are 3-5 times the size of a typical reactive follicle. Although PTGC is reported in 3.5-10% of chronic lymphadenopathy, head and neck surgeons do not often experience this condition and its clinical implications. Al-thoug PTGC is benign disease, it could not be excluded the association with other malignant lymphoid diseases. Therefore, periodic follow up of PTGC patient could be required. We report two cases at this study ; a 16 years old man who visited out-patient clinic due to palpable mass of right cervical area, several months ago, and a 35 years old man who visited out-patient clinic for evaluating right cervical mass. Both of two patients were diagnosed with PTGC. In this study, we focus on the clinic-pathologic features of this uncommon disease along with other literature reviews.
