Esophageal cancer in Yemen

To document the age and gender distribution, histopathologic type as well as grading characteristics of Esophageal Cancer [EC] in Yemen. A case series. Department of Pathology, Sana'a University, Sana'a, Yemen, from January 2005 to December 2011. Three hundred twenty five cases of EC were included for review. The diagnoses were made on hematoxylin and eosin stained sections and the cases were categorized into Squamous Cell Carcinoma [SCC] and adenocarcinoma [ADC]. Out of the 325 EC cases, 163 [50%] were SCC [females 67%, males 33%] and 158 [49%] were ADC [females 30%, males 70%]. The rest of the cases were 2 adenosquamous carcinoma and 2 non-Hodgkin's lymphoma. The mean age, for SCC was 60 years while the mean age for ADC was 65 years. The peak incidence for SCC was found in the age groups of fifth and sixth decades for females and in fifth and seventh decades for males. The maximum number of patients with ADC was seen in sixth and seventh decades for both gender. Well-differentiated histological grading accounted for 247 [77%] for both genders and types. The moderately differentiated and poorly differentiated accounted, for 17% and 6% respectively. The EC in Yemen had a predominance of SCC in female patients and predominance of ADC in male patients which was usually of a well-differentiated grade

Childhood lymphomas in Yemen. Clinicopathological study

To find out the frequency of childhood lymphomas in all ages, and to describe patterns of lymphomas in relation to gender and site in Yemen. This is a descriptive record-based study of 1167 cases of lymphomas diagnosed by 3 pathologists in the Department of Pathology, Sana'a University, Sana'a, Yemen from 1st January 2004 to 30th December 2007. The diagnoses were made on hematoxylin and eosin stained, and categorized non-Hodgkin's lymphoma [NHL] according to the National Cancer Institute Working Formulation classification, and Hodgkin's disease [HD] according to Rye classification. Out of 1167 lymphomas, 801 [68.6%] were NHL, and 366 [31.4%] were HD, amongst these 347 [29.7%] were patients aged

Histologic pictures of male infertility in Yemeni patients

To define subgroups of male infertility and frequency of focal normal spermatogenesis in multiple testicular biopsies of non-obstructive asoozpermia in Yemeni patients. A descriptive record based study of 485 cases of male infertility was carried out in the in vitro fertilization [IVF] center in Sana'a, Yemen during the period from 1st August 2000 to 30th December 2007. During histological analysis the sample was evaluated regarding the size of seminiferous tubules, the thickness of tubules, the relative number and types of germ cells, the degree of fibrosis, and presence of focal normal spermatogenesis. The results were commonly classified according to the used clinical practical classification. Out of a total of 485 testicular biopsies, 164 [33.8%] cases showed germ cell aplasia. The fibrosis represented the lowest frequency being 93 [19.2%] cases. Obstructive asoozpermia was present in 99 [20.4%] cases, and maturation arrest in 116 [23.9%] cases. Focal normal spermatogenesis was found in 106 [27.5%] out of 385 cases of non-obstructive asoozpermia with higher frequency in fibrosis cases [36.6%]. We have shown in this study the different histopathologic patterns in our local patients, which correlate with some studies and shows discrepancies with others. Therefore, these findings are informative for concerned IVF centers to help the patients who are suffering from primary infertility
