Background. In the Nigerian setting the curriculum of each medical school is the sole responsibility of the senate of the respective university. This arrangement results in variability in learning objectives and in students' acquisition of skills to manage clinical problems. Educational objectives can be used to both standardise and evaluate ...

Background. The aim of the study was to investigate the demographics, aetiological factors, anatomical lesions, biological features, management protocol and outcomes of patients admitted with major burn injuries to the Nelson Mandela Academic Hospital (NMAH), which is one of only three tertiary hospitals in the Eastern Cape and is in ...

* Struma ovarii is a monodermal variant of ovarian teratoma. Thyroid-type carcinoma arising in struma ovarii is rare. The most common type is papillary carcinoma, followed by typical follicular carcinoma, and the new entity of follicular carcinoma--highly differentiated follicular carcinoma of ovarian origin; other forms occur rarely. Consensus on the ...

* Hidradenocarcinomas are rare, aggressive skin adnexal tumors of sweat gland origin that demonstrate a high potential for local recurrence, metastasis, and poor outcome. These neoplasms can derive from preexisting clear cell hidradenomas but more commonly appear de novo, with the molecular events responsible for the pathogenesis currently unknown. Historically, ...

* Appendiceal goblet cell carcinoid (GCC) is a rare tumor with histologic features of both adenocarcinoma and neuroendocrine tumor (carcinoid). Clinically, it behaves more aggressively than classic appendiceal carcinoid and commonly presents with peritoneal carcinomatosis. We report 2 cases of appendiceal GCC, one with uterine cervical involvement and the other ...

* Context.--Gene expression profiling of diffuse large B-cell lymphoma using complementary DNA microarrays has revealed 2 major prognostic groups in Western countries: germinal center B-cell-like and nongerminal center B-cell-like lymphomas. Immunohistochemical analysis using antibodies specific for CD10, BCL6, and MUM1 has been proposed as a surrogate for gene expression profiling.
