Aim: Malignant renal tumour is a relatively rare type of cancer that occurs third in urological tumours after prostate and bladder cancers. Little is known in the literatures about its existence in Sokoto which prompted this research. This study was carried out to determine the prevalence and histopathological pattern of malignant renal tumours in Sokoto, Nigeria. Methods: A total of 11,554 H&E stained sections were reviewed from 2001 to 2012. Patient's data such as age and sex were analyzed from 36 samples which were confirmed for renal tumours. Result: Nephroblastoma has the highest occurrence in malignant cases (48.4%) followed by renal cell carcinoma (41.9%) and transitional cell carcinoma (9.68%). It was observed that nephroblastoma (15 cases) was most prevalent in the 0-7 year age group showing it is a childhood tumour, while the other ones occurred mostly in the adults. Conclusion: Nephroblastoma has the highest occurrence in malignant renal cases in Sokoto, Nigeria.

Background: Breast cancer is one of the most important tumours affecting women in Nigeria and all over the world, with high morbidity and mortality if detection is delayed. Objectives: This study was carried out to review the histology of all breast biopsies sent to Histopathology Laboratory in UDUTH. Method: Using haematoxylin and eosin staining method, breast biopsies received from January 2002 to December 2011 were analyzed. Demographic data such as age, sex, site of the biopsy of all the patients were obtained through histology request card and biopsy registers. Result: A total of 788 breast samples were received during the period under review, 403 samples (51.1%) were benign lesions, 256 samples (32.5%) malignant lesions and 61 samples (7.7%) are inflammatory lesions. The age group with the highest occurrence of breast pathology is 20-29 years which are mostly benign lesions, with 50-59 years age group having the highest occurrence of malignant lesions. Conclusion: The study indicated that most breast lesions occurring in the first three decades of life are benign, while those in the elderly are mostly malignant. We recommend strong awareness among the populace to encourage early detection of these lesions.
