ABSTRACT: When detecting a proliferative splenic lesion, veterinarians usually choose splenectomy before a conclusive diagnosis, which can provide a deleterious effect to the dog. The most appropriate would be to perform splenectomy as a therapeutic procedure only in cases with real surgical indication, which can be established after defining microscopic diagnosis and prognosis. The objectives of this study were: to determine the frequency of different types of lesions in spleens of splenectomized dogs in the period of 12 years (2006-2017); determine the representativity of neoplastic lesions (benign and malignant) and non-neoplastic lesions; to evaluate and compare the safety and efficiency of fine needle aspiration biopsy (FNA) and ultrasound-guided Tru-cut needle biopsy for cytological and histopathological diagnosis, respectively, of splenic nodular lesions. In the studied period 224 cases of lesions were found in splenectomized spleens. The frequency of non-neoplastic lesions (50,45%, 113/224) and neoplastic lesions (49,55%, 111/224) was very similar. Among the neoplastic lesions, the malignant ones were more frequent (79,27%, 88/111), and the hemangiosarcoma was the most common (52,25%, 58/111). The possibility of malignant neoplasm was about 74% greater than a benign one. In summary, it was verified that 60.71% (136/224) of the cases corresponded to benign lesions without indication to splenectomy. FNA techniques and Tru-cut biopsy showed a low risk of complications. Regarding the diagnostic efficacy, the FNA obtained 71.43% (15/21) of conclusive diagnoses, 60% (9/15) of which were compatible with the final result of the histopathological evaluation, after splenectomy (gold standard). The Tru-cut biopsy obtained 71.43% (5/7) of conclusive diagnoses and 28.57% (2/7) of inconclusive diagnoses. Among the conclusive one, in 100% of the cases the diagnosis was compatible with the gold standard. Thus, since the possibility of benign splenic lesions in dogs is 1.52 times greater than malignancies, splenectomy should be recommended as a therapeutic procedure only in cases with proven surgical indication, which can be established after definition of microscopic diagnosis and prognosis. The use of FNA and Tru-cut biopsy should be recommended, especially for small and focal splenic lesions, since such techniques are good alternatives for establishing diagnosis previously to splenectomy, which may reduce the number of unnecessary splenectomies. The importance of recommending such techniques is emphasized, especially for dogs with focal splenic lesions smaller than three centimeters.

Introduction: Urinary bladder cancers are heterogeneous diseases consisting of a divergent group of tumors.  Diseases of the urinary bladder, both neoplastic and nonneoplastic contribute to notable mortality and morbidity. Histopathology remains the gold standard of diagnosis. Bladder transurethral resection of the tumor is a therapeutic procedure that ensures the material necessary for histopathological diagnosis because it allows assessment of the degree of differentiation, depth of tumor invasion, parameters useful in the elaboration of diagnosis and prognosis assessment Material and Methods: All the urinary bladder biopsies submitted in the pathology laboratory during 1 year time period were included in the study. Results: Among the 51 total cases in the study, the male to female ratio was 4.67:1 with the age group of 22-96 years. Among the study population, 30 (52.7%)  presented with hematuria, 10 (19.2%)  with burning micturition, frequent urination, and lower abdominal pain. In the study, 44 (86%) showed neoplastic lesions while 7(14%) remaining were non-neoplastic lesions. Infiltrative urothelial carcinoma with low and high grades was diagnosed in  23% (12/51) Conclusions: This study has revealed that neoplastic lesions are more common than non-neoplastic lesions. A great majority of neoplastic lesions are of urothelial origin. Majority of which are invasive urothelial neoplasm. All urothelial neoplasms are more common in males. Cystoscopic studies and biopsies help in the early detection of bladder neoplasms and they form the mainstay of the diagnosis and follow-up.

ABSTRACT Background: Conventionally Pleural effusions are suspected by history of pleuritis, evaluated by physical signs and multiple view radiography. Trans-thoracic pleural aspiration is done and aspirated pleural fluid is considered the gold-standard for pleural effusion. Chest sonography has the advantage of having high diagnostic efficacy over radiography for the detection of pleural effusion. Furthermore, ultrasonography is free from radiation hazards, inexpensive, readily available  and feasible for use in ICU, pregnant and pediatric patients. This study aims to explore the diagnostic accuracy of trans-thoracic ultrasonography for pleural fluid detection, which is free of such disadvantages. The objective is to determine the diagnostic efficacy of trans-thoracic ultrasound for detecting pleural effusion and also to assess its suitability for being a non-invasive gold-standard.   Subject and Methods: This retrospective study of 4597 cases was conducted at pulmonology  OPD-Gulab Devi Teaching Hospital, Lahore from November 2016 to July 2018. Adult patients with clinical features suggesting pleural effusions were included while those where no suspicion of pleural effusion, patients < 14 years and pregnant ladies were excluded. Patients were subjected to chest x-ray PA and Lateral views and chest ultrasonography was done by a senior qualified radiologist in OPD. Ultrasound-guided pleural aspiration was done in OPD & fluid was sent for analysis. At least 10ml aspirated fluid was considered as diagnostic for pleural effusion. Patient files containing history, physical examination, x-ray reports, ultrasound reports, pleural aspiration notes and informed consent were retrieved, reviewed and findings were recorded in the preformed proforma. Results were tabulated and conclusion was drawn by statistical analysis. Results: Out of 4597 cases, 4498 pleural effusion were manifested on CXR and only 2547(56.62%) pleural effusions were proved by ultrasound while 2050 (45.57%) cases were reported as no Pleural effusion. Chest sonography demonstrated sensitivity, specificity, PPV, NPV and diagnostic accuracy 100 % each. Conclusions: Trans-thoracic ultrasonography revealed an excellent efficacy that is why it can be considered as non-invasive gold standard for the detection of pleural effusion.

Background: Although endoscopic retrograde cholangiopancreatography (ERCP) is accepted as the gold standard, there is a place for magnetic resonance cholangiopancreatography (MRCP) and diffusion-weighted imaging (DWI) in the diagnosis of obstructive biliary disorders.Aim: To compare the findings of MRCP with ERCP in patients with obstructive biliary disorders and to investigate the diagnostic efficacy of MRCP combined with DWI.Study design: Retrospective, analytic, cross-sectional study.Methods: The MRCP images of 126 patients who underwent both MRCP and ERCP owing to biliary obstruction were reviewed. Nine patients were excluded because of incomplete diagnostic workup or a long period (>3 months) between MRCP and ERCP. Ninety-two patients underwent DWI, which was also evaluated. The sensitivity, specificity and accuracy of MRCP and DWI were analysed.Results: The sensitivity, specificity and accuracy of MRCP according to ERCP results as the gold standard was 97%, 71% and 93% for assessment of biliary dilatation; 100%, 94.7% and 97.5% for the diagnosis of choledocholithiasis; 93.7%, 100% and 99% for the identification of benign strictures; 100%, 100% and 100% for the diagnosis of malignant tumours; and 100%, 100% and 100% for the detection of complicated hydatid cysts; respectively. The sensitivity and specificity of DWI for the diagnosis of malignant tumour was 100%. In the detection of choledocholithiasis, the sensitivity and specificity of DWI was 70.8% and 100%.Conclusions: MRCP is an alternative, non-invasive, diagnostic modality, comparable with ERCP for the evaluation of pancreaticobiliary diseases. DWI can be helpful for diagnosis of choledocholithiasis and tumours.

Rare Case Report

Background: Osteosarcoma is a malignant neoplasm that occurs most often in long bones, with the head and neck region being rarely affected, accounting for less than 1% of all cancers in this region. Objective: To report a rare case of a large-extension osteosarcoma with emphasis on its clinical and diagnostic aspects. Case presentation: A 43-year-old woman presenting an intraoral exophytic lesion with involvement of other maxillofacial structures, such as nostril, zygoma and orbit. Despite the initial clinical diagnosis of actinomycosis, an incisional biopsy confirmed the histopathological diagnosis of osteosarcoma, showing a wide morphological variety. Conclusion: This case highlights the importance of clinical and histopathological findings for the correct diagnosis of osteosarcoma. Moreover, it shows that, although surgical resection is the primary treatment for this neoplasia, depending on the extent of the tumor and its proximity to vital anatomical structures, the most appropriate conduct is not always feasible.

Background: Breast tumours are very common cause of morbidity and mortality worldwide specially in developing countries. Breast lesions show broad spectrum of disease patterns in respect to benign, malignant, and non-neoplastic. Breast cancer is one of the most frequently occurring cancer among women. Objective: To study the frequency, age distribution, clinical and histological patterns of neoplastic and non-neoplastic lesions of breast in this rural population. Material and methods: This observational study was conducted over a duration of three years. In which we studied 210 cases of breast lesions. Specimens were received in department of pathology. Grossing, tissue processing, staining done according to standard protocol. Haematoxylin and eosin (H&E) stained sections were examined under microscope to categorise different type of lesions in the form of non-neoplastic and neoplastic. Results:  Out of 210 breast lesions, fibroadenoma was the commonest (114 cases) benign lesion. While invasive ductal carcinoma (70 cases) was commonest in malignant category. Non neoplastic lesions stand on third place, study showed 6 cases out of 210 total cases, in which acute mastitis (4 cases) was most common. Benign tumours were mostly seen in 2nd and 3rd decade and malignant tumour mainly in 5th and 6th decade Conclusion: Early histopathological diagnosis of breast lesions is very important to differentiate between benign and malignant lesions. Large number of cases of invasive ductal carcinoma (>33% of all cases) were seen in our study, which is a serious concern. So, generation of awareness among women is need of time to reduce the morbidity and mortality specially in Indian rural setup

Aim: To outline various histopathological types of ovarian cysts received in our teaching hospital along with their prevalence and mode of presentation and to assess the proportion of physiologic versus pathological cysts and benign versus malignant ovarian cysts. Duration of study: From Jan 2019 to March 2021. Methods: Histopathology Department of Bakhtawar Amin Medical & Dental College & Hospital, Multan. A retrospective review of 122 ovarian lesions including physiological/functional cysts, pathological non neoplastic cysts as well as benign, borderline and malignant neoplasm. Histopathology reports of all ovarian specimens were reviewed and counted. Details like age, marital status, parity, presenting complaints, procedure opted, laterality, size, gross and microscopic details and final histological diagnosis etc were recorded. H&E stained slides of all cases were reviewed. In difficult suspicious cases, immunohistochemistry was also carried out. Percentage and proportions were calculated for all the variables. Relevant tables and charts were computed. Results: A total of 122 ovarian specimens with some lesion were segregated in histopathology department of Bakhtawar Amin Hospital from 117 patients with 5 patients having bilateral lesions. The mean age was 33.2 years (ranging from 13-71 years). Most ladies presented between 25-45 years of age. Out of these 117 patients, 18 ladies were unmarried. Out of the 99 married, 12 were nulliparous. Sixty four ladies (54.7%) found to have cysts/neoplasm in right sided ovary, forty eight (41%) presented with left sided ovarian involvement and 5 (4.3 %) presented with bilateral ovarian lesions. Conclusion: Non neoplastic ovarian cysts are more frequent as compared to neoplastic masses. Histopathological diagnosis is mandatory for final confirmatory diagnosis.

INTRODUCTION: The skin being largest organ of the body has vast spectrum of disorders which can be difcult to diagnose correctly solely on the basis of clinical features. Hence histopathological examination is necessary to categorise skin lesions. The aim was to study relative frequency of various skin lesions and distribution of these lesions according to age and sex. METHODS: This is a retrospective descriptive hospital based study. The skin biopsies samples which came in the duration of two years from January 2019 to December 2020 at the Department of Pathology, Sardar Patel Medical college and associated group of hospitals, Bikaner, Rajasthan were taken in this study. All skin biopsies that showed denite histopathological diagnosis were included. After proper xing and staining procedures these lesions were examined under light microscopy and categorized as non-neoplastic and neoplastic. Relative frequency of various lesions, distribution of lesions according to age and sex was analyzed. The data collected was tabulated, interpreted and compared with other similar studies. RESULTS: Out of 346 patients, incidence of neoplastic lesions 259 (74.9%) were higher than non-neoplastic lesions 87(25.1%). Males were affected more compared to females with male to female ratio 1.45:1. Non-neoplastic lesions were mostly caused because of infectious etiologies among which leprosy was the most common infection. Keratinocytic tumors 99(52.2%) constituted most common type of neoplastic lesion. Benign tumors 191(73.7%) outnumbered malignant tumors 68(26.3%). The cases of benign tumors were seen more in younger population while that of malignant tumors were seen in older age groups. Among the keratinocytic type of malignant skin tumors squamous cell carcinoma (63.5%) was the most common variant which was followed by basal cell carcinoma 19(36.5%). Male predominance was observed in both squamous cell carcinoma and basal cell carcinoma. CONCLUSION: A wide heterogenesity of skin lesions was observed in the present study . These skin lesions were mostly affecting age group of 10-30 years. Inspite of extensive programmes and research, leprosy and tuberculosis remains a rampant cause of infectious non-neoplastic skin lesions. Sometimes ignorance by patient for a very small appearing skin lesions becomes life threatening. Hence early clinician consultation with proper examination and accurate histopathological diagnosis becomes the mainstay in early treatment and recovery.

Abstract Background The purpose of this study is to explore the combined diagnostic value of anti-cyclic citrullinated peptide antibody (A-CCP), rheumatoid factor (RF) and imaging result in early rheumatoid arthritis, and the role of A-CCP and RF in prediction for radiological outcomes. Methods 101 patients with rheumatoid arthritis and 97 control individuals were detect their A-CCP, RF and radiological joint changes, the diagnostic efficacy of the respective indicators and the combined indicators was analyzed by logistic regression model. Results Our results showed that values of A-CCP and RF were significantly higher in the RA group than in the normal group. Receiver operating characteristic curve results show that the sensitivity of RF is higher than A-CCP and radiological outcome, and specificity of CCP is higher than RA and radiological outcome, and the diagnostic ability of combination of RF, A-CCP and radiological outcome is the strongest. Furthermore, RF and A-CCP had high significant OR for radiological joint damage and progression. Conclusions Our study indicated that the combined diagnosis of RF and A-CCP with radiological outcome can improve the diagnostic efficacy of RA, and RF and A-CCP are independent predictors of radiological damage and progression.

Background: Leiomyomas are benign tumors of smooth muscle cells commonly encountered in women of reproductive age group. Aim of this study was to conduct a histopathological study of leiomyomas in hysterectomy specimens and to correlate them with clinical findings.Methods: A prospective study was done on 130 hysterectomy specimens clinically diagnosed as leiomyoma. The specimens were subjected to histopathological examination.Results: In this study, the most common age group was 31-50 years (87.69%). Most common complaint was menorrhagia (51.54%). In endometrium, the most common histopathological diagnosis was proliferative phase (46.15%) followed by endometrial hyperplasia (19.23%). The most common secondary change was hyalinization and the most common site was intramural (62.9%).Conclusions: Hysterectomy is a commonly performed procedure in the management of uterine leiomyomas. The ultimate diagnosis and prognosis depends on the histopathological examination; therefore, every operated specimen must be subjected to histopathology.
