However, the rates of false-negative and false-positive diagnosis remain a challenge for pathologists. Objectives: To assess the value of thyroid fine-needle aspiration as a screening tool and its accuracy of diagnoses relative to final histological diagnoses. Patients and Methods: A chart review was conducted of all adult patients who underwent fine-needle aspiration of thyroid nodule(s) and were subjected to thyroid surgery at King Abdulaziz Medical City, Jeddah, Saudi Arabia, between January 2007 and June 2014. The fine-needle aspiration results were correlated with final histopathology results. Results: Of the 408 aspirates from 373 patients, the Bethesda System for Reporting Thyroid Cytology (BSRTC) diagnostic categories were as follows: nondiagnostic in 26 aspirates (6.4%); benign in 128 (31.4%); atypia/follicular lesion of undetermined significance in 52 (12.7%); follicular neoplasm/suspicion for a follicular neoplasm in 83 (20.3%); suspicious for malignancy in 23 (5.6%) and malignant in 96 (23.5%). The comparative histopathological diagnoses were benign in 192 (47.1%) and malignant in 216 (52.9%) aspirates. The calculated risk of malignancy in the fine-needle aspiration categories was 34.6% in diagnostic category (DC) I, 15.6% in DC II, 50% in DC III, 52% in DC IV, 95.7% in DC V and 100% in DC VI. The sensitivity of fine-needle aspiration with BSRTC was 88.9%, specificity was 75.6%, positive predictive value was 79.7%, negative predictive value was 84.4% and accuracy was 81.5%. Conclusion: The results of this retrospective study demonstrated higher risks of malignancy in DC I, DC II, DC III and DC IV than that of the original BSRTC definition, along with a higher specificity and positive predictive value for cancer diagnosis, and a lower sensitivity and negative predictive value.

Cutaneous side effects due to levetiracetam are rarely reported in the literature. In this article, we describe a patient with skin hyperpigmentation due to the treatment with levetiracetam with complete resolution after discontinuation of the medication. In addition, we review the topic and hypothesize the mechanism behind this rare complication. To the best of our knowledge, this is the first report of skin hyperpigmentation as a side effect of levetiracetam in the literature. The prescribing physicians should inform the patients about all potential side effect of levetiracetam including skin hyperpigmentation. Similar to many undiagnosed conditions, increased awareness of their existence is the key to diagnosis. Early recognition and timely cessation of therapy are important to reverse this effect. Further studies should be conducted to explore the pathophysiology of this r...

We report a case of colonic adenosquamous carcinoma with MSI-H (microsatellite instability-high) ... more We report a case of colonic adenosquamous carcinoma with MSI-H (microsatellite instability-high) in a 43-year-old male who presented with bowel obstruction due to a circumferential mass involving the descending colon and splenic flexure. Microscopically, it showed poorly differentiated adenocarcinoma with squamous differentiation, tumor infiltrating lymphocytes >3/high-power field, and mild peritumoral lymphocytic response. Immunohistochemistry was equivocal for MLH-1, PMS-2, and MSH-2, with retention of MSH-6 expression. Polymerase chain reaction testing demonstrated MSI-H pattern with instability of BAT-25, BAT-26, and NR-21. Review of the literature revealed only one recently published case of MSI-H adenosquamous carcinoma. The role of MSI in adenosquamous carcinoma pathogenesis is still unknown. In conclusion, MSI testing in colonic adenosquamous carcinoma combined with other MSI-related clinical and histological features is indicated.

The patient was a known case of panhypopituitarism for 5 years. Comprehensive patient evaluation including FNAC with papillary thyroid cancer result then she underwent total thyroidectomy and bilateral neck dissection and final histologic examination confirmed papillary thyroid carcinoma in the background of lymphocytic thyroiditis, associated with Langerhans cell histiocytosis (LCH). The draining cervical lymph nodes were also involved by LCH and metastatic papillary thyroid carcinoma. Although the association of LCH with papillary thyroid carcinoma in the thyroid has been reported, their co-existence with LCH in the draining lymph nodes is very uncommon.

We report here a child with chronic iron deficiency anaemia, melena and skin lesions. She had severe hypochromic microcytic anaemia. Upper and lower endoscopy revealed hundreds of red-bluish polypoid lesions involving the entire GI tract primarily of the small bowel. Due to localisation of the most severe lesions, the patient responded well to surgical treatment, allowing a sustained clinical remission.

MALT lymphoma of the lacrimal gland usually presents as a localized disease process in extranodal tissues. The treatment options of MALT lymphoma of the lacrimal gland chiefly include radiation of the tumor, chemotherapy, surgical removal, or a combination of these strategies. We report a case of localized MALT lymphoma of the lacrimal gland, with prolonged sustained remission after eradication of gastric Helicobacter pylori (H. Pylori) infection. He sustains in remission of lacrimal MALT lymphoma for four years without chemotherapy or radiotherapy.

Chronic GVHD can occur after previous or ongoing acute GVHD or in patients without a history of acute GVHD (eg, de novo disease) as illustrated by this case. In evaluating a patient presenting with chronic diarrhea more than 100 days after BMT, one must consider a serious underlying illness such as chronic GVHD because it is a major cause of morbidity and mortality of allogeneic stem cell transplantation. As indicated by this case, chronic GVHD can cause diarrhea. Complete evaluation of the diarrhea state should be part of the initial investigation. In many cases, however, the diagnosis of GVHD is not straightforward, and gastrointestinal biopsy and histologic confirmation is often necessary to corroborate a clinical impression of chronic GVHD.

The index case presented with hoarseness and characteristic skin lesions. Some of the patients had photosentivity with milia and hypertrichosis. The diagnosis of lipoid proteinosis was confirmed by histopathology and by the findings of normal blood porphyrin levels. The condition is inherited as an autosomal recessive disorderm and consanguinity was an important factor. The rarity of this condition and the common occurrence of close-relative intermarriages in Saudi Arabia prompted this report, which we believe is the first and largest family with lipoid proteinosis possessing an established Arabian ancestry.

Only those patients in whom liver biopsy was performed for a tissue diagnosis were included. Fifty patients were investigated, all below the age of 12 years, of whom 36 were male and 14 female. Thirty-two were of neonatal-infantile group, 11 had a diagnosis of neonatal giant cell he hepatitis of infections origin and an intact biliary tree. Two had septic shock and one had leishmaniasis. The remaining 18 patients of the neonatal-infantile group constituted five case of glycogen storage disease, six of infantile obstructive cholangiopathy (biliary atreasia), four of fatty change and one each of congenital hepatic fibrosis, neuroblastoma and nonspecific reactive hepatitis. The eighteen older children had the following diagnoses: thalassemia in five, sickle cell disease in four, two each of Re...
