A histopathological and immunohistochemistry analysis of endometrial lesions among women presenting with abnormal uterine bleeding.

Objectives: We aimed to histopathologically evaluate the morphological spectrum, apoptotic index (AI), and mitotic index (MI) of endometrial lesions in patients presenting with abnormal uterine bleeding (AUB). Methods: A cross-sectional study was done over a period of 18 months where a total of 60 newly diagnosed cases of perimenopausal women presenting with AUB were included. All H and E stained pathology slides from the specimens were reviewed for initial histopathological evaluation and diagnosis. Immunohistochemistry for Bcl-2 and Bax was done. The study subjects were divided into two groups: Group 1 included 30 cases of histologically proven proliferative endometrium (PE) and endometrial polyps and Group 2 included 30 cases of hyperplasia, endometrial epithelial neoplasia (EIN)/or carcinoma. For all cases, AI and MI were calculated and compared among the two groups. Statistical Analysis: Quantitative variables were compared using the Independent t-test/Mann-Whitney test between the two groups and Kruskal-Wallis test for comparison between more than two groups. Qualitative variables were correlated using the Chi-square test. P < 0.05 was considered statistically significant. Results: In our study of 60 patients of AUB, the mean age was 45.87 years with a parity of 2 or more in most of the patients. Most of the patients in our study had heavy menstrual bleeding (66.67%) with associated complaints of weakness, pallor, and low backache. Out of 60 patients of AUB, Endometrial carcinoma was diagnosed in 13 (21.67%) patients, with the most common histopathological type being Endometrioid carcinoma. There was a significant difference in the AI, MI, and the ratio of AI/MI among various histopathological diagnoses. AI was highest for Endometrial carcinoma and lowest for hyperplasia and polyps. MI was also highest for Endometrial carcinoma and lowest for hyperplasia and polyps. However, the ratio was incongruent as it was highest for hyperplasia without atypia and lowest for PE with endometrial carcinoma being midway. The Bcl-2 expression of relatively benign conditions (Group 1) was significantly higher than Group 2 (Endometrial epithelial neoplasia/carcinoma). Bax intensity showed an almost inverse pattern, being highest in endometrial carcinoma and lower in hyperplasia and polyps with the lowest expression in PE. Even the Bcl-2:Bax ratio was also highest for PE and lowest for endometrial carcinoma with others falling in between them. Conclusion: It can be concluded that the combination of the proliferative and apoptotic markers and the ratio will help as a tool in aiding the diagnosis of endometrial lesions for patients presenting with AUB.

Critical Analysis of Laboratory Requisition Forms Received in a Cytopathology Laboratory of a Tertiary Care Centre: An Audit and Review of Literature.

Background: A laboratory requisition form (LRF) is the main communication link between the laboratories and the clinicians. In a cytopathology laboratory, incomplete forms with inadequate information significantly impact the quality of the results and waste precious time of the lab. Aims: The aim of this study was to audit the LRFs for adequacy of demographic and clinical data and to analyze the reasons for the same. Settings and Design: A retrospective study was conducted in the cytopathology laboratory of a tertiary care center. Materials and Methods: All the original LRFs received for Pap smears and FNACs of 1-month duration were retrieved. The forms were scrutinized for the presence of specific parameters which were classified as patient information, clinician information and clinical information. In addition to the completeness of the form, clarity of the data was also noted. Statistical Analysis: The data were entered on excel worksheets and percentage of Pap smear and FNAC forms lacking information of various parameters was calculated. Results: A total of 431 LRFs were received in the month of January 2020. These included 274 Pap smear LRFs and 157 FNAC LRFs. Patient information was mentioned in predominantly all the forms, however, clinician and clinical information, which is indispensible for reporting, was missing in a significant proportion of the Pap smear and fine needle aspiration cytology (FNAC) forms. Conclusions: Receiving inadequately filled LRFs has been an age-old problem in all medical laboratories. Audit of inadequacy of LRFs helped in assessing the prevailing practices in the hospital and gave an insight into the quality of information available to the cytologists for reporting. Many clinicians withhold information out of ignorance about its importance or due to lack of time to fill up the details on the LRF. Also, filling out a LRF is a task usually delegated to the junior doctor in the OPD and the significance of filling the LRF correctly and comprehensively is often not emphasized upon adequately by the senior clinicians. This audit helped us taking preventive action by giving feedback to the clinicians and emphasizing to them the importance of clinical data on the LRF and in improvising the LRF using a more objective and user-friendly format.

Toward early diagnosis of oral cancer: Diagnostic utility of cytomorphological features, a pilot study.

INTRODUCTION: Early detection of oral cancer is one of the most efficient ways to reduce the high mortality from this disease because of the ready accessibility of the oral cavity. We need to devise urgent diagnostic tools to detect early oral premalignant and malignant lesions. AIM: The aim of the present study was to grade the oral lesions in an attempt toward developing a novel cytological grading system. Further, morphometric analysis of cellular parameters was also performed to compare their significance in differentiating benign from malignant lesions. MATERIALS AND METHODS: The present study was conducted at a tertiary care hospital catering to the low socioeconomic population. Patients presenting in the various Out Patient Departments with suspicious oral lesions were evaluated by cytology in the Department of Pathology. RESULTS: A total of 72 patients were evaluated with a mean age of 43.54 ± 10.35 years. The involvement of the buccal mucosa was the most common site of oral lesions. Cytologically, the lesions were graded according to the oral/oro-pharyngeal cytology grading system into grades A to F. Cyto-morphometric analysis showed an increasing trend in mean nuclear diameter from benign to malignant cases while the mean cytoplasmic diameter decreased, value of P < 0.05 was observed indicating a statistically significant difference between the two groups. CONCLUSIONS: Cytological features of pleomorphism are a unique feature in oral carcinoma reflecting intracellular alterations in cells. Grading of lesions according to cytological characteristics can be helpful in standardizing the reporting of the oral lesion. However, our study was restricted by limited data; we emphasize more extensive studies to assess the usefulness and applicability of such a grading system. We also conclude that the use of cytomorphometry can improve the diagnostic reliability of exfoliative cytology.

Pancreatic and Gastric Heterotopia in the Gallbladder: A Rare Incidental Finding.

Heterotopic or ectopic tissue is a congenital anomaly, which is defined as the presence of the tissue outside its normal location, without neural, vascular, or anatomic connection with the main body of an organ in which it normally exists. This tissue is usually discovered incidentally and may be asymptomatic or may present with nonspecific gastrointestinal (GI) symptoms. Pancreatic and gastric heterotopia are the two predominantly occurring heterotopic tissues in the GI tract.[12] The prevalence of ectopic pancreatic tissue in the GI tract ranges from 0.6% to 13.7% of autopsy series and it can be present anywhere in the GI tract with the most common localizations being stomach (27.5%), duodenum (25.5%), colon (15.9%), esophagus, and Meckel's diverticulum.[345] It is a rare finding in the gallbladder and its prevalence has not been ascertained due to lack of large-scale studies and systematic review of literature. Similarly, heterotopic gastric tissue is common throughout the GI tract from the tongue to the rectum,[67] but it is extremely rare in the gallbladder with only around 34 cases reported in literature so far, while other cases of different types of heterotopic tissues in the gallbladder such as liver tissue and others such as adrenal and thyroid tissues have been described.[8] The most common presentation of ectopic tissue in the gallbladder is colicky pain in the epigastrium or right upper quadrant sometimes associated with nausea and vomiting. Here, we are presenting two incidentally detected cases, each of gastric and pancreatic heterotopias in the gallbladder.

Cichorium intybus attenuates streptozotocin induced diabetic cardiomyopathy via inhibition of oxidative stress and inflammatory response in rats.

The aim of the present study was to investigate the effects of Cichorium intybus on lipid peroxidation activities of both enzymatic and non-enzymatic antioxidants, inflammatory mediators, myocardial enzymes and histopathology of cardiac tissues in experimental diabetic cardiomyopathy (DCM). DCM was induced by single intraperitoneal injection of streptozotocin (STZ) (40 mg/kg) combined with high energy intake in rats. Seed extract of Cichorium intybus (CIE) (250 mg/kg & 500 mg/kg) was administered orally once a day for 3 weeks. Phytochemical investigations of seed extract revealed presence of some active ingredients such as alkaloids, tannins, saponin, phenols, glycosides, steroids, terpenoids and flavonoids. Seed extract of Cichorium intybus confirmed a significant potency towards restoring the blood glucose, an elevation of the levels of aspartate aminotransferase (AST), lactate dehydrogenase (LDH), superoxide dismutase (SOD), thiobarbituric acid reactive substances (TBARS), blood glutathione (GSH), TNF-α and IL-6 and a reduction in the levels of catalase (CAT) was observed following the STZ treatment. Oxidative stress was accompanied by myocardial degeneration as evidenced by histopathological examination of cardiac tissues. Administration of CIE reduced the lipid peroxides level in heart. Serum levels of AST, GSH, LDH and SOD were brought down to physiological levels by CIE in STZ induced DCM rats. CIE also markedly down-regulated serum TNF-α and IL-6 levels. Catalase that was reduced in serum was brought back to near normal level. The extensive necrotic changes of cardiac tissue by STZ was minimized to normal morphology upon CIE administration. The study demonstrates the cardioprotective effect of CIE via inhibition of oxidative stress and pro-inflammatory cytokines.

Pitavastatin ameliorates myocardial damage by preventing inflammation and collagen deposition via reduced free radical generation in isoproterenol-induced cardiomyopathy.

Pitavastatin inhibits 3 hydroxy 3 methyl glutaryl coenzyme A (HMGCoA) reductase enzyme, preventing cholesterol synthesis along with elevating high density apolipoprotein A1 (Apo-A1). The present study was designed to evaluate cardioprotective potential of pitavastatin at 1 mg/kg/day and 3 mg/kg/day dose for 14 days in low dose isoproterenol (ISO) (5 mg/kg/day for 7 consecutive days) induced myocardial damage. ISO administration induced significant reduction in endogenous antioxidant enzymes like reduced glutathione (GSH), superoxide dismutase (SOD), catalase (CAT) and raised thiobarbituric acid reactive substances (TBARS) indicating activated lipid peroxidation. Along with this, a significant increase in level of cardiac injury biomarkers vie, creatine kinase (CK-MB), lactate dehydrogenase (LDH), aspartate amino transferase (AST), tumor necrosis factor (TNF-α) and transforming growth factor (TGF-ß) as well as brain natriuretic peptide (BNP). Histological examination also revealed marked myocardial tissue damage in ISO treated rats. However, pretreatment with pitavastatin (3 mg/kg/day) significantly maintained nearly normal levels of cardiac biomarkers and oxidant antioxidant status as well as lipid peroxidation in ISO induced MI rats. Cardiac histological assessment and infarct size assessment also showed marked reduction in myocardial architecture alteration including infarct size as well as collagen deposition by pitavastatin that strongly supported biochemical findings. These observations strongly corroborate that pitavastatin prevents myocardial damages via up regulation of endogenous oxidants along with its hypocholesterolemic activity.

Poorly differentiated carcinoma of thyroid: Case report of an uncommon entity.

Malignant thyroid tumors of follicular origin comprise a spectrum, with the indolent well-differentiated thyroid carcinoma (WDTC) at one end and lethal anaplastic thyroid carcinoma (ATC) at the other. Poorly differentiated thyroid carcinoma (PDTC) lies intermediately between WDTC and ATC in terms of morphology and prognostic standpoint. This thyroglobulin producing neoplasm accounts for 4-7% of all thyroid malignancies. PDTC has been controversial due to lack of defined diagnostic criteria. We hereby report a case of PDTC in a 42-year-old female presenting with neck swelling, pain, and dysphagia for 10 months. She was diagnosed as colloid goiter on fine-needle aspiration cytology. On imaging, a large complex thyroid with central neck nodes was seen. Total thyroidectomy and central neck node dissection were done. Based on the morphology, immunostaining, and the diagnostic criteria, a diagnosis of PDTC was made. PDTC is a diagnostic challenge due to its rarity and previous equivocal diagnostic criteria.

Diagnostic challenges of tubercular lesions of breast.

INTRODUCTION: Tuberculosis (TB) in the developing countries presents with both pulmonary and extrapulmonary manifestations. Breast TB, however, remains a rare presentation. Its importance lies in the fact that it may mimic malignancy or present as inflammatory lump/abscess. AIMS AND OBJECTIVE: The aim of the present study is to highlight the importance of breast TB and its diagnostic challenges. MATERIALS AND METHODS: It was a retrospective study conducted at a tertiary care hospital, over 2 years between 2013 and 2015 during which eight cases of breast lesions were diagnosed as of tubercular origin. RESULTS: Granulomas were seen in five cases while three cases revealed only few epithelioid cells, and necrosis was seen in all cases on fine-needle aspiration cytology. Histopathological evaluation was available in six out of the eight cases, while acid-fast bacilli were positive in three cases, the characteristic granulomas were seen in all the six cases evaluated. CONCLUSION: Significance of TB breast lies in the fact that it may masquerade as breast malignancy or pyogenic abscess. India is a developing country where TB is endemic, a high index of suspicion should be expressed in evaluating breast masses, and TB should be considered in the differential diagnosis.

Clinicopathological Study of Eosinophilic Cholecystitis: Five Year Single Institution Experience.

INTRODUCTION: Gallbladder diseases are very common in Northern India, most common of which is Chronic Cholecystitis. Rarely, histopathological diagnosis of Eosinophilic Cholecystitis (EC) is given when transmural cellular infiltrate consists of more than 90% eosinophils. AIM: To determine the prevalence and clinicopathological profile of eosinophilic cholecystitis at a tertiary care hospital of New Delhi. MATERIALS AND METHODS: This was a retrospective clinicopathological study done on twenty two cases of eosinophilic cholecystitis over a period of five years from January 2011- December 2015. In cases diagnosed histopathologically as eosinophilic cholecystitis, clinical details were obtained from hospital records and slides were retrieved. Various histologic features, pattern of the inflammatory infiltrate and association of EC with other medical diseases, drugs and allergic states were evaluated. RESULTS: Out of a total of 1370 cholecystectomy specimens received during five year period, Eosinophilic cholecystitis was diagnosed in 22 (1.6%) of the specimens. Clinically, seven of these patients had a clinical diagnosis of acute cholecystitis. Patient's age ranged from 25-64 years and male to female ratio was 1:2.7. Most common symptom reported was abdominal pain. Most of the cases showed gallstones radiologically (90%) while only two cases showed peripheral eosinophilia (9%). Histologically, mucosal and muscular eosinophilic infiltrate was seen in 72.6% of the cases. No association with drug therapy, allergies or other pre-existing medical conditions was noted. CONCLUSION: EC is a relatively uncommon entity in which histopathology remains the main stay of diagnosis. Although the presentation may be similar to general cholecystitis, if a postoperative histopathological diagnosis of EC is made, then the patient must be investigated thoroughly to rule out other associated disease conditions, which may have a worse prognosis than cholecystitis itself.

Coexistence of tuberculosis and malignancy: a mere coincidence or a causal association.

Tuberculosis (TB) and malignancy are among the most important current global health problems. Many authors suggest that their coexistence is a chance association owing to their high prevalence. There is, however, enough evidence that one condition may predispose the other. In our retrospective report of two cases, TB in draining lymph nodes was discovered incidentally on histopathology, following surgical resection for malignancy. The possibility of coexistent lesions, especially in regions endemic for TB, mandate a detailed histopathological examination to prevent the chances of diagnostic failure and thus therapeutic error.

Tuberculosis 'The Great Imitator': A usual disease with unusual presentations.

BACKGROUND: A number of infectious diseases have been referred to by the phrase 'The Great Imitator', of which the oldest is syphilis; others include Lyme disease, nocardiosis, etc. Tuberculosis has been described as the second great imitator as it can imitate various other disease processes. An awareness of the atypical clinical manifestations of tuberculosis is important, especially in regions where tuberculosis continues to be a major public health problem, such as India. Extrapulmonary tuberculosis (EPTB) constitutes about 15-20% of all cases of tuberculosis in immunocompetent patients and accounts for more than 50% of the cases in human immunodeficiency virus (HIV)-positive individuals. METHODS: We hereby report 4 cases of tuberculosis at unusual sites, which were not suspected clinically and were subsequently diagnosed by pathological examination and by ancillary techniques. OBSERVATIONS AND RESULTS: In all the four cases, the involvement was extrapulmonary in nature and at unusual sites. Three cases were diagnosed by a positive Ziehl Neelsen stain while culture for Mycobacterium tuberculosis was positive in three cases. All the four patients tested negative for HIV status on serology. CONCLUSIONS AND IMPLICATIONS: Unusual presentations, which mimic many diverse conditions, as seen in this series, highlight the importance of a high index of suspicion in the timely diagnosis of tuberculosis. Evidence of systemic or lung involvement may not always be present and laboratory and radiological findings play an important role.

Expression of Apoptosis Related and Proliferative Proteins in Malignant Lympho-Proliferative Disorders.

BACKGROUND & OBJECTIVE: The current study aimed to perform an immunohistochemical analysis of patterns of apoptotic and cell proliferative related protein expression in different histological grades and immune phenotypes of malignant lymphomas and other lymphoproliferative disorders. METHODS: This observational study was carried on 60lymph node biopsies of lymphoproliferative disorders. The biopsies were analyzed histologically and immunohistochemically. RESULTS: A total of 60 lymph node biopsies were included in the study, of which 81.6% were of malignant lympho-proliferative lesions. The majority of the biopsies were B-cell (66%) and were grouped in the intermediate grade. Bax and BCL-2 protein expression was presented by percentage of immune positive neoplastic cells per 10fields and graded on a scale of 1 to4. A Bcl-2, Bax Protein Ratio (BBPR) was determined for each case by dividing the estimated Bcl-2 protein (percentage of Bcl-2 positive cells x Bcl-2 staining intensity) by the estimated Bax protein (percentage of Bax positive cells x Bax immunostaining intensity). The mean BBPR was found to be significantly higher in indolent lymphomas (2.64 ± 1.3) as compared to aggressive lymphomas (0.47 ± 0.9) (P<0.01). The expression of P53 and PCNA in 35 biopsies of Non Hodgkin Lymphomas (NHL) was found to increase from low to high grade tumors. CONCLUSIONS: A significant correlation was found between BBPR and predicted biological behavior of indolent and aggressive lymphomas. This indicates the important role of Bcl-2 and Bax in biological behavior of lymphomas. Furthermore, P53 and PCNA expression were found to increase from low to high-grade tumors suggesting their prognostic value in NHL.

Inflammatory Pseudotumor of the Spleen Masquerading as Splenic Malignancy.

Inflammatory pseudotumors (IPTs) of the spleen are extremely rare, benign tumors of unknown etiology, and are most frequently detected incidentally. We report a case of IPT of the spleen in a 19-year-old male, who presented to the Hamdard Institute of Medical Sciences and Research, New Delhi, with a history of pain and heaviness in the left hypochondrium. On clinical examination, splenomegaly was detected. Ultrasonography and contrast-enhanced computed tomography of the abdomen revealed an enlarged spleen with a mass lesion completely occupying the lower pole of the spleen. Therefore, a diagnosis of splenomegaly with a malignant splenic lesion was suggested. Open splenectomy was performed. On gross examination, a well-circumscribed nodular growth measuring 9 × 8 × 5 cm in diameter was seen on the lower pole of the spleen, which on cut section appeared tan white with foci of yellowish discoloration. Microscopic examination of the nodular growth revealed spindle cells in a hyalinized stroma with inflammatory infiltration of predominantly plasma cells and lymphocytes. On immunohistochemistry, the spindle cells were positive for smooth muscle actin. A diagnosis of IPT of the spleen was rendered following histopathology testing. Splenectomy is both diagnostic and curative for this rare entity, and prognosis is usually favorable following the procedure.

An Incidental Primary Papillary Carcinoma Arising in a Thyroglossal Duct Cyst: Report of a Rare Finding.

The thyroglossal duct cysts (TGDCs) are the most common congenital anomaly of the thyroid, usually manifested as painless midline neck mass. Malignancy is very rare and is reported in around 1% of cases as an incidental finding after histopathological evaluation of resected cyst. Papillary carcinoma is the most common carcinoma reported in TGDC. Here, we report a case of 17-year-old-female, who presented with a gradually increasing midline neck mass which moves with swallowing. On imaging a diagnosis of infected TGDC was made. The Sistrunk operation was done and a diagnosis of primary papillary carcinoma arising in a TGDC was rendered histopathologically. The contemporary appearance of papillary carcinoma thyroid was reported in about 20% cases of TGDC carcinoma, thus it is essential to differentiate primary papillary carcinoma arising in a TGDC from those of metastatic papillary carcinoma thyroid by strict diagnostic criteria.

A Critical Appraisal of the Spectrum of Image Guided Fine Needle Aspiration Cytology: A Three Year Experience from a Tertiary Care Centre in Delhi.

OBJECTIVE: Image guided fine needle aspiration cytology (FNAC) is a safe, simple, rapid, cost effective and accurate modality in evaluation of deep seated lumps (abdominal, pelvic and intrathoracic masses) which are unapproachable by blind FNAC. In this study, a critical analysis of the utility of image guided FNAC in deep seated and otherwise inacessible mass lesions was carried out. MATERIAL AND METHOD: Fifty-four ultrasound (USG) or computed tomography (CT) guided FNACs from lumps at any location in the body, that is, thoracic, abdominal, pelvic etc over a period of 3 years (January 2012- December 2014) were included in the study. The most common site aspirated, the indications for a guided aspiration and the accuracy of aspiration cytology in comparison to the histological diagnosis were evaluated, wherever possible. RESULTS: Fifty-four image guided FNACs were performed (46 USG guided and 8 CT guided). Inconclusive, inflammatory, benign tumors, suspicious and malignant lesion rates were 5.6%, 29.6%, 11.1%, 5.6%, and 48.1%, respectively. The most common site was the liver (25.5%), followed by the thyroid (18.5%), lung (14.8%), gallbladder (11.1%), and lymph nodes (7.4%). Cytohistological correlation could be performed in 32 cases with a diagnostic accuracy of 100%. CONCLUSION: FNAC coupled with a diagnostic imaging technique such as USG or CT can improve the diagnostic yield and a definite diagnosis can be reached in most of the cases.

Clinco-Pathological Patterns in Women with Dysfunctional Uterine Bleeding.

BACKGROUND: The term dysfunctional uterine bleeding (DUB) refers to any abnormal bleeding from the uterus, unassociated with tumour, inflammation and pregnancy. The histological diagnosis of DUB is very essential for adequate management especially in perimenopausal and postmenopausal females. The present study was undertaken with the aim of evaluating DUB in various age groups, carry out histopathological study of the endometrium and analyze its clinic-pathological patterns. METHODS: The study included 500 cases of atypical uterine bleeding, out of which 120 cases of DUB were included based on clinical features and detailed investigations. Study was conducted in Jawaharlal Nehru Medical College, Aligarh Muslim University, between March 2003 to December 2004 Endometrial tissue was collected by D&C procedure and the samples were sent for histopathological evaluation by pathologist. RESULT: Hyperplasia was the commonest endometrial pathology (20.5%) followed by luteal phase insufficiency (15.6%) and secretory endometrium (13.7%). Endometritis including tubercular endometritis (12.7%), post abortal (5.8%), proliferative (6.8%), polyp (3.9%), atrophic (3.9%), exogenous hormone changes (2.9%) and anovulatory cycles (6.8%) made up for the remaining lesions. CONCLUSION: DUB occurs secondary to a wide variety of functional and structural abnormalities, warranting a thorough evaluation especially in perimenoupausal females. Menorrhagia is a common symptom and the most likely etiology relates to the patient's age. Significant number of endometrial samples revealed pathology rendering endometrial curetting and biopsy an important procedure. Cervical cytology is a valuable adjunct however histopathology remains the gold standard in diagnosis.

Delayed Uterine Necrosis: Rare Cause of Nonhealing Wound.

Uterine necrosis is a very rare condition and most of the reported cases occurred after pelvic arterial embolization for post-partum haemorrhage, embolization of fibroid uterus or application of B-Lynch sutures. A case of delayed myometrial necrosis is reported in post-cesarean patient where no embolization or uterine compression sutures have been applied. Patient presented with foul smelling discharge from the gaped abdominal wound following caesarean section. Abdomen was closed after exploration and lavage. Patient did not have complete healing and area of unhealed wound remained through which subinvoluted uterus was peeping out. Patient was taken for resuturing again but the uterus was found to be completely necrotic and hysterectomy was performed. Patient responded to treatment.

Cystic Change in Pleomorphic Adenoma: A Rare Finding and a Diagnostic Dilemma.

Pleomorphic adenoma forms the majority of salivary gland neoplasms. Cystic change in pleomorphic adenomas is a diagnostic dilemma and can mimic mucoepidermoid carcinoma, mucocele or carcinoma ex pleomorphic adenoma and squamous cell carcinoma. Hereby we report this interesting and rare case of cystic pleomorphic adenoma in a 32-year-old male.

Primary Endometrial Squamous Cell Carcinoma In Situ: Report of a rare disease.

Squamous cell carcinoma (SCC) of the endometrium, whether primary or secondary to cervical cancer, is a rare entity. Primary endometrial squamous cell carcinoma in situ is even more uncommon; it usually occurs in postmenopausal women and has a strong association with pyometra. We report a 60-year-old multiparous postmenopausal woman who presented to the Hakeem Abdul Hameed Centenary Hospital, New Delhi, India, in May 2014 with a lower abdominal swelling corresponding in size to a pregnancy of 26 gestational weeks and vaginal discharge of one year's duration. A total abdominal hysterectomy with a bilateral salpingooophorectomy was performed, which revealed an enlarged uterus with pyometra. Histopathology showed that the entire endometrial lining had been replaced with malignant squamous cells without invasion of the myometrium. Immunohistochemistry revealed that the tumour cells were positive for p63 with a high Ki-67 labelling index. No adjuvant therapy was required and the patient was disease-free at a seven-month follow-up.

Postoperative thrombocytosis: An unusual case report.

Thrombocytosis is often an incidental finding seen in 35-50% of cases and the cause determination creates a diagnostic challenge. Extreme thrombocytosis is rare and seen in 2-5.8% patients only. Among the various causes of increased platelet count, surgical procedures have attracted much attention in both experimental and clinical domain. The appearance of thrombocytosis after surgery needs to be diagnosed to establish the type of thrombocytosis (clonal or reactive), as treatment and prognosis are quite different between them. This case report is vital because of two reasons: First, the increase in platelet count is difficult to rationalize than many of the other thrombocytoses, such as those related to primary augmentation of the function of the bone marrow; second, the association of platelets with the clotting process has led to the belief that their increase after a surgical procedure is connected with the occurrence of postoperative thrombosis. This case presents an interesting finding from a patient who has undergone major abdominal surgery and has shown an unexpected perpetual increase in platelet count.
