    Ir J Med Sci, 2016 Feb;185(1):249-57.
    PMID: 25894278 DOI: 10.1007/s11845-015-1287-4
    BACKGROUND: The anatomy of the vermiform appendix shows variations in its macroscopic dimensions and microscopic features, some of which have potentials of influencing the clinical aspects of the appendix.

    AIM: The aim of this study was to find out some microscopic features of appendix and evaluate the correlation between the microscopic features of the appendix and the age of the subjects and to determine whether these findings should influence the clinical implications of appendix.

    METHODS: In this cross-sectional observational study, thirty adult males' (age from 18 to 67 years) postmortem appendices and adnexa from Bangladeshi victims of road traffic accidents were sectioned at the base, midzone and tip stained with H+E stain and examined under microscope. Measurements were taken at the base, at the midzone and at the tip of the appendix, and the mean of the three measurements was considered as the overall value.

    RESULTS: The overall number of mucosal glands in a section ranged from 42.33 to 130.00 and the number of the germinal centres varied between 2.33 and 10.00. The overall luminal diameter ranged between 1764.58 and 3208.33 µm. The overall luminal diameter in more than 52 % of cases was between 2700.00 and 3299.99 µm with a median value of 2750 µm.

    CONCLUSION: The overall number of mucosal glands showed a tendency towards a positive correlation with age. The overall luminal diameter and the overall number of germinal centres showed a tendency towards a negative correlation with the age. However, none of the tendencies of correlation reached statistically any significant level.

    We encountered a patient with a tongue base lymphoma that we initially diagnosed as a lingual tonsil in view of its benign appearance. We established the correct diagnosis of Waldeyer ring lymphoma by histology. This case led us to conduct a study of all cases of Waldeyer ring lymphoma that had been treated at our center during a 10-year period. We retrospectively examined our case records and found 35 such cases. From this group, we excluded 5 cases because of incomplete data. Thus our final study group was made up of 30 patients-14 males and 16 females, aged 14 to 76 years (mean: 51.6; median 54). The primary presenting signs and symptoms were dysphagia (n = 17 [57%]), a neck mass (n = 7 [23%]), nasal symptoms (n = 5 [17%]), and pain (n = 1 [3%]). Only 4 patients (13%) had B symptoms. A total of 20 patients (67%) presented with tonsillar involvement, 8 (27%) with nasopharyngeal involvement, 1 (3%) with tongue base lymphoma, and 1 with anterior tongue involvement. Most patients (77%) presented at an early stage. Histologically, 25 patients (83%) had high-grade diffuse large B-cell lymphoma, 4 (13%) had T-cell lymphoblastic lymphoma, and 1 (3%) had follicular lymphoma. Twenty-one patients (70%) were treated with chemotherapy, 4 (13%) received adjuvant chemotherapy with either radiotherapy or surgery, 3 (10%) resorted to other forms of treatment (primarily traditional remedies), and 2 (7%) declined treatment altogether. There were 14 patients (47%) alive at the end of the study period.
