Background:We undertook this study to determine the relative frequencies of childhood malignancies and their age – sex distribution in this environment.Materials and Methods:Hospital-based data of histological and cytologically confirmed cases of malignancies in children, aged ≤ 15 years, was collated over a period of 11 years, from the Cancer Registry.Results:A total of 329 children aged ≤ 15 years, with confirmed malignant disease, was recorded. This constituted 8.44% of all malignancies diagnosed in the same period with a Male : Female ratio of 1.5:1. Burkitt’s lymphoma accounted for 27.01% of the cases followed by retinoblastoma (17.02%), non-Hodgkin’s non-Burkitt’s Lymphoma (9.42%), and Rhabdomyosarcoma (9.42%). Others were Nephroblastoma (8.81%), Hodgkin’s lymphoma (6.69%), Neuroblastoma (3.34%), Colorectal carcinoma (2.43%), Osteosarcoma (2.13%), and Unspecified lymphomas (1.82%). Burkitt’s lymphoma was most prevalent in the 5–9 and 10–15 year age groups, retinoblastoma in the 0–4 year age group, and Non–Hodgkin’s lymphoma, Hodgkin’s lymphoma, and unspecified carcinomas were more prevalent in the 10–15 year age group.Conclusion:Lymphomas were the most prevalent malignancies of childhood seen in this region and the majority were of the Burkitt type, in contrast to the predominant leukemic and central nervous system trend seen in developed nations.

Primary gastrointestinal angiosarcomas are very rare and those of the small bowel even more rare. We report a case which is the first in the literature from this part of the world. It presented in a 25-year-old woman with multiple dissemination and rapid fatality. Diagnosis was based on histological morphology using Hematoxylin and Eosin (H and E) stains, plus reticulin special stain to outline the vascular nature.

BackgroundProbably benign breast lesions in the Breast Imaging Reporting and Data Systems (BI-RADS 3) constitute a crucial category and a considerable number of all palpable breast masses. Local data concerning the outcome of such lesions in the Nigerian environment is almost non-existent.ObjectivesThe goal of this article is to report the frequency, outcome and malignancy detection rate among palpable breast masses that were categorised on ultrasound as BI-RADS category 3 (probably benign) according to the American College of Radiology (ACR).MethodsBetween January 2015 and July 2017, 603 patients had diagnostic whole-breast ultrasound scans. There were 277 women who complained of palpable breast masses, of whom 151 women were diagnosed as having BI-RADS 3 lesions. The final lesion outcome was determined by either biopsy or ultrasound follow-up examination for a total of 2 years. All data were recorded and analysed with Statistical Package for the Social Sciences (SPSS) version 20 (Chicago, USA).ResultsThe frequency of BI-RADS category 3 lesions among all the women who underwent breast ultrasound was 25% (151/603); and 54% (151/277) in patients with palpable breast masses. There were 25 patients who were excluded because of incomplete data or who were lost to follow-up. A total of 122 patients had both ultrasound examination and histopathologic diagnosis, while only 4 were followed up for 2 years on ultrasound alone. Of the 122 women biopsied, 117 (95.9%) had benign histologic outcomes, and of the remaining 5, cancer was confirmed in 2 (1.6%), while the remaining 3 patients (2.5%) had lesions considered intermediate at histology (juvenile papillomatosis, borderline phylloides and atypical ductal hyperplasia). Three out of four patients who had ultrasound follow-up alone had stable lesions after 2 years, while one patient had complete resolution.ConclusionThis study found a significantly high biopsy rate of 80% (122/151) for probably benign lesions but a low detection rate for malignancy (1.6%). Follow-up with imaging rather than biopsy for lesions sonographically described as probably benign, will reduce medical costs and unwarranted invasive procedures.

Pseudoangiomatous stromal hyperplasia (PASH) is an uncommon benign mesenchymal tumor of the breast. Majority occur as diffuse lesions, and diagnosis is often incidental or in a background of other breast pathologies. Bilaterality with multiple tumoral masses in giant breasts is a rarity. We report a 34-year-old nonlactating female with 2-year history of rapid progressive painless bilateral enlargement of the breasts following surgical excision of ill-defined breast lumps which were not subjected to histopathological evaluation a year earlier. Examination revealed bilateral nontender giant breasts extending to the umbilical area with masses which were not attached to overlying skin, Grade 2 pressure ulcers on the lateral posterior breast aspects bilaterally and peau d’orange. There were no other palpable masses or lymph nodes. A clinical assessment of bilateral gigantomastia was made. Bilateral mastectomy revealed giant PASH which was confirmed with positive immunohistochemical reactivity for CD34 and vimentin. No other breast pathologies were seen with extensive sectioning. Diffuse multiple breast lesions with incomplete excision are associated with rapid growth in PASH as seen in this case. The presence of concurrent bilateral giant tumoral masses without any underlying breast pathology is a novelty. The mainstay of treatment in this case is mastectomy despite its benign nature.
