Urinary bladder cancer in adults: a histopathological experience from Madinah, Saudi Arabia.

OBJECTIVE: To delineate the frequency and clinicopathological features of urinary bladder cancer. METHODS: This retrospective study was conducted at the King Fahd Hospital, Madinah, Saudi Arabia, and comprised medical records related to bladder tumours, from January 2006 to October 2015. Data was obtained from histopathologic reports and evaluated for age, gender, cystoscopic findings and histopathological characteristics at the time of presentation. RESULTS: Of the 116 cases, 96(82.7%) were of men while 20(17.3%) were of women. The mean age was 62.4±15.62 years (range: 20-115 years). Transitional cell carcinoma was the most common histological type, seen in 111(95.7%) cases, followed by adenocarcinoma 3(2.6%) and squamous cell carcinoma 2(1.7%). Of the transitional cell carcinoma cases, 78(70.5%) were superficial, while 33(29.5%) were muscle invasive. Most of the transitional cell carcinoma cases 72(65%) were of lower grade (grade I and II), while 39(35%) were of grade III. CONCLUSIONS: Our hospital-based pathology experience of urinary bladder cancer was comparable with earlier studies.

Clinicopathologic Patterns of Adult Renal Tumors.

BACKGROUND AND AIM: Adult renal tumors (ARTs) are rare as compared with tumors of other organs and systems; however, it is important to have demographic and pathology data of rare tumors, including ART. No such data are available from the Kingdom of Saudi Arabia (KSA). Therefore, we aimed to study the demographic and pathological data of ART from King Fahad Hospital, Al-Madinah, KSA. MATERIALS AND METHODS: This is a retrospective study of computerized data from the histopathology laboratory of King Fahad Hospital during a 10-year period (January 2006-September 2015). RESULTS: There were 42 cases of ART, comprising 28 males and 14 females (male:female ratio of 2:1). The study group ranged in age from 17 to 83 years, with a mean of 54.5 years. In the study cohort, 93% of the patients had malignant tumors and 7% had benign lesions. Renal cell carcinoma (RCC) accounted for 85.8% of cases, followed by squamous cell carcinoma and sarcoma. The benign tumors recorded in our series were oncocytoma (4.7%) and angiomyolipoma (2.4%). The tumor size of RCC ranged from 4 to 17 cm, with a mean of 7.4 cm. The majority of patients (68%) had Fuhrman Grade II tumor. Gross capsular invasion, renal vein invasion and lymph node metastases were present in one case each. CONCLUSION: We conclude that the pathological findings of ART from the Madinah region are in concordance with studies in national and international literature.

Ghost cell odontogenic carcinoma of the maxilla: a case report with a literature review.

The aim of this report is to present a rare case of a Ghost cell odontogenic carcinoma (GCOC) of a 21-year-old man with review of the literature. The patient was treated surgically, and one of the surgical margins was involved, the patient received adjuvant radiotherapy for local control. Five months later, patient presented with infraorbital lesion which was proven histological to be GCOC. Radiological images, histological sections and clinical photographs are also presented. One year after the second surgery, the patient was tumor free. The only effective treatment modality was surgical removal.

Oral malignant melanoma: a rare case with unusual clinical presentation.

Primary Oral malignant melanoma is a rare tumor with an indigent prognosis. This is a case report of 47-year-old Sudanese female diagnosed as Oral malignant melanoma of the mandible with an unusual pattern of growth and clinical presentation. Furthermore, a possibility of intraosseous origin is suggested.

Pattern of lymph node pathology in western Saudi Arabia.

BACKGROUND: This study aimed to characterize the histopathological pattern of lymph node pathology among Saudi patients and to highlight the age and gender variations of these lesions as base line data. MATERIALS AND METHODS: We retrospectively analyzed the data from lymph node biopsy specimens received at the Department of Pathology, King Fahad Hospital, Madinah, Saudi Arabia from January 2006 to December 2013. RESULTS: Of the 289 lymph node biopsy specimens received, 154 (53.3%) were from males and 135 (46.7%) from females giving a male: female ratio of 1.14:1. Age of the patients ranged from 2.5 to 96 years with a mean age 33.9 years. The commonest lymph node group affected was the cervical (30.4%) followed by axillary (9.7%) and inguinal (8.7%). Malignant lymphoma [71 Hodgkin's disease (HD), 57 non Hodgkin's lymphoma (NHL)] 128 (44.3%), reactive hyperplasia 68 (23.5%), and tuberculosis 41 (14.2%) were the common causes of lymph node enlargement. While HD, reactive hyperplasia and tuberculosis were commonest in young adult patients (10-29 years old) and rare above the age of 50 years; NHL was the predominant cause of lymph node enlargement above 50 years. CONCLUSIONS: Lymph node biopsy plays an important role in establishing the cause of lymphadenopathy. Among the biopsied nodes, lymphomas were the most common (44.3%) followed by non-specific reactive hyperplasia (23.5%) and tuberculous lymphadenitis (14.2%).

Histopathologic characterization of prostate diseases in Madinah, Saudi Arabia.

AIMS: To delineate the histopathological pattern of prostate diseases and to highlight age variations in prostate specific antigen (PSA) values and histopathological features. MATERIALS AND METHODS: A retrospective review was made of all prostate biopsy reports seen between January 2006 and December 2013 at the King Fahad Hospital, Madinah, Saudi Arabia. Prostate lesions were tabulated and classified into benign and malignant groups. Histological scoring of adenocarcinomas was accomplished using the Gleason system. PSA values were correlated with Gleason scores. RESULTS: Of 417 prostate lesions reviewed, 343 (82.3%) were benign and 74 (17.7%) were malignant, giving a benign to malignant ratio of 4.6:1. Benign prostatic hyperplasia (both with and without inflammation) was the commonest prostatic lesion and accounted for 80.3% of all cases and 97.6% of all benign cases. The age range was 20 to 97 years with a mean of 69.2 years and a peak age group at 70-79 years. Seventy one cases of adenocarcinoma accounted for 95.9% of the total of 74 malignant tumors. It showed an age range of 44 to 95 years, a mean age of 70.9 years and peak prevalence in the 80-89 year age group. Gleason score seven was the most frequent (39.4%) in occurrence. Most adenocarcinomas, 41 cases (57.7%), were moderately differentiated (Gleason score of 5-7). PSA values ranged widely between 16-1,865 ng/ml with a mean of 363.4 ng/ml. Elevated PSA (>100 ng/ml) levels were found in 53 (81.6%) patients. There was a statistically significant positive correlation between serum PSA level and Gleason score (p=0.0304). CONCLUSIONS: Prostatic lesions constitute a significant source of morbidity among adult males in Madinah. Benign prostatic hyperplasia was the commonest benign prostatic lesion and adenocarcinoma was the commonest histological subtype of prostatic cancer.
