Objective:
To find out the pattern, trend and site distribution of extranodal lymphomas in Ibadan.
Design:
Case series.
Setting:
Department of Pathology, University College Hospital.
Subjects:
All cases of malignant lymphomas with extranodal manifestations between 1981 and 1998.
Main Outcome Measures:
Frequency and distribution of primary extranodal lymphomas.
Results:
Extranodal lymphomas constituted 9.8% of non-Hodgkin's lymphomas(NHLs) during the period, increasing from 8.5% of NHLs from 1980 to 1990 to 12.4% from 1991 to 1998. During the entire 18 year period the nasal/nasopharynx, gastro-intestinal tract (GIT), tonsils and skin were the most commonly affected sites constituting 20.2%, 19.3%, 14.3% and 13.4%, respectively of all extranodal lymphomas. However, between 1980 and 1991 the GIT was the most commonly affected site (26.1%) followed by the nasal/nasopharyngeal region (11.6%). The involvement of the nasopharyngeal area during the second period of the study accounted for 32.0%.
Conclusion:
The reasons for this changing trend are unknown and the significance of HIV infection in this regard is uncertain.

The spleen is a vital organ in the lymphatic system, nestled in the upper left side of the abdomen. It is composed of two primary regions: the red pulp and the white pulp, each having distinct functions. The red pulp performs a significant role in blood filtration. It efficiently purges the blood of old or damaged red blood cells and...
