Cervical cancer screening by molecular Pap-transformation of gynecologic cytology.

BACKGROUND: Cervical cancer is one of the common cancers in women accounting for 7.9% of all cancers. In India it is the second commonest cancer in women. The immortality of the cancer cell and the relatively long time frame from acquisition of infection to development of cervical cancer was established. As major advancements like LBC, HPV testing were introduced in the recent years, screening has taken a new avatar, the Molecular pap!! The objectives of this study were: To compare gynecologic cytology and abnormal results with respect to conventional and LBC. To study the role of HPV cotesting and ancillary tests performed, that is, HPV CISH, and p16ink4a by IHC. METHODS: About 71 924 Conventional and LBC samples were included from August 2009 to December 2017. Cases for HPV testing along the conventional smears were 1539. HPV can be tested from the same LBC vial as the sample remains stable at room temperature for 6 weeks. HPV DNA PCR was carried out in our laboratory for High and Low risk genotypes. Cytology findings were also correlated with histology. RESULTS: Detection rate of SILs in LBC samples were higher (2.20%). The commonest abnormality was LSIL in LBC and ASCUS in conventional smears. Commonest HR HPV and LR HPV detected was 1 61 856 and 61 142. CONCLUSION: LBC with HPV cotesting improves sensitivity and specificity and reduces ambiguous results; allows better compliance, as a negative result of both tests allows patients to get screening every 5 years, thereby increasing screening intervals, important in a resource limited situation.

Giant Perivascular Epithelioid Cell Tumor of the Orbit: A Clinicopathological Analysis and Review of the Literature.

AIM: To describe and review the clinical, radiological, and histopathological characteristics of an orbital perivascular epithelioid cell tumor (PEComa). METHODS: A systematic review of clinical records, radiological investigations, microscopic features, and immunohistochemical characteristics was done. RESULTS: A 9-year-old female child presented with a year-long history of a large orbital mass associated with painless, progressive proptosis of the right eye. Radiologically, a well-defined orbital mass was seen with no intracranial extension. Excision was performed and histopathological examination showed uniform epithelioid cells in nests separated by thin fibrovascular septae. The tumor cells stained positively for Human Melanoma Black-45, but neg-atively for desmin, S-100, smooth muscle actin, MyoD1, microphthalmia-associated transcription factor, vimentin, CD10, CD31, and CD34 with a low proliferation index of 5-7%. Based on the tumor's morphological and immuno-histochemical characteristics, a diagnosis of giant orbital PEComa was made. No recurrence was seen at the last follow-up. CONCLUSIONS: PEComas are uncommon mesenchymal neoplasms that have typical histological features, with an immunohistochemical profile of negativity for epithelial markers and positivity for melanocytic markers. For benign PEComas, complete excision is advised. However, since PEComas elsewhere in the body have been known to be malignant, a close follow-up of such cases is recommended.

Solid variant of orbital angioleiomyoma: An unusual tumor at an unusual site.

We describe the clinicopathological features of a solid variant of orbital angioleiomyoma. A review of clinical records, diagnostic, and radiographic studies combined with histopathological evaluation with standard histochemical staining and immunohistochemistry was conducted. A 22-year-old male patient presented with a mass in the region of the left lacrimal gland that was gradually increasing over the past 2 years. Radiological and clinical examinations showed no signs suspicious of a malignancy and fine needle aspiration cytology was inconclusive. Therefore, an excision biopsy was performed. On histopathological examination, the picture was consistent with a benign spindle cell tumor. Immunohistochemistry showed positivity for CD 34 and CD 31 (markers for vascular endothelium). The tumor also showed positivity for smooth muscle actin and Ki-67 proliferative index was low. Angioleiomyomas are rarely encountered in the orbit and has features seen in leiomyoma as well as some vascular tumor elements. In most cases, surgical excision is usually curative.

Unusual ganglioglioma with extensive calcification and ossification.

Ganglioglioma is a slow-growing relatively low-grade mixed glioneuronal tumor with most cases corresponding to the WHO Grade I category. It frequently presents with seizures. The temporal lobe is the most common location followed by frontal, parietal, and occipital lobes. These generally behave in a benign fashion and have a favorable prognosis. We describe a case of a 24-year-old male presenting with convulsions and a calcified parieto-occipital mass. This mass removed from the parietal lobe showed neoplastic glial and dysplastic neuronal tissue amidst extensive areas of calcification and foci of ossification. On immunohistochemistry, the glial component expressed glial fibrillary acidic protein whereas the dysplastic neuronal component expressed synaptophysin and CD34. Epithelial membrane antigen was negative and Ki-67 showed a low proliferative index. After the surgery, the patient is free of neurological symptoms. Widespread calcification and ossification are very unusual in ganglioglioma, which prompted us to report this case.

Bone marrow abnormalities in HIV infected children, report of three cases and review of the literature.

Bone marrow abnormalities in HIV infected adults include hypocellularity, myelodysplasia and poor marrow recovery. Data in children is limited. We report a series of three HIV infected with varied bone marrow abnormalities. First child was a 7-year-old boy with pulmonary tuberculosis, anemia, thrombocytopenia and bone marrow examination showed hypoplastic marrow. He succumbed to his disease within seven days of hospitalization. Second child was a three and a half year old girl who had severe anemia and her bone marrow examination showed dyserythropoiesis. Third child was a 7-year-old boy who had splenic abscesses and pancytopenia and bone marrow examination showed myelofibrosis with increased plasma cells. He also succumbed due to a fatal pulmonary bleed. Thus, advanced HIV disease in children can lead to bone marrow suppression in form of hypoplasia or myelofibrosis which can be fatal.

Lymphoma in HIV patients: Varied presentations.

Although lymphomas have been reported in patients with acquired immunodeficiency syndrome, it has rarely been reported from the Indian subcontinent. We present three human immunodeficiency virus-infected patients (two adults and one child) who had non-Hodgkin's lymphoma - plasmablastic variety, Hodgkin's lymphoma - nodular sclerosis type II and B cell lymphoma, respectively.

Incidence and prognostic factors associated with biliary atresia in western India.

AIM: To estimate the incidence of biliary atresia(BA) amongst neonatal cholestatic syndromes (NCS) and determine prognostic factors in BA patients who have undergone Kasai's portoenterostomy. Study design- Retrospective analysis. SETTING: Pediatric Hepatobiliary Clinic at B.J. Wadia Children's Hospital, Mumbai. METHODS AND MATERIALS: 32 patients diagnosed with BA referred to the clinic from May 2005 to July 2007 were included in the study. All patients underwent a detailed history, clinical examination and were tested for liver function tests (LFT), USG abdomen, liver biopsy, intra-operative cholangiogram and CMV tests. Patients were followed up for a period of 1 month to 7 years post operatively and complications such as cholangitis, progress to liver cell failure and cirrhosis was noted. RESULTS: Incidence of BA amongst NCS (n = 88) was 36.4%. 8 patients of BA (25%) were lost to follow up. Out of the remaining, 10 (41.7%) improved and 14 (58.3%) did not improve. The mean age of presentation was 89 + 55.8 days. 1 patient (25%) out of 4 with bile duct size of < 100 microns showed an improvement whereas 3 (37.5%) out 8 patients with bile duct size 100-200 microns showed improvement and 4 (50%) with bile duct size of > 200 microns had improvement post Kasai surgery. Those with bile duct sizes > 200 microns had better prognosis than those with sizes 100-200 microns (Odd's ratio = 1.8) and < 100 microns (Odd's ratio = 3). 12 patients (50%) were operated before 3 months of age and 50% of them responded to surgery. The remaining 12 patients were operated after 3 months of age and only 33% showed any improvement. (Odd's ratio = 2). Other parameters like SGOT (P = 0.598), SGPT (p = 0.901), total Bilirubin (p = 0.349), Direct Bilirubin (p = 0.429), Alkaline Phosphatase (p = 0.605) and GGTP (p = 0.480), cirrhosis (p = 0.417), degree of fibrosis (p = 0.384), degree of inflammation (p = 0.964) and Cholangitis (P = 0.388) had no effect on the outcome. CONCLUSION: Biliary Atresia is a common cause of NCS in India. Children with Bile duct size > 200 microns have a good prognosis. Portoenterostomy before 3 months of age has a better outcome.

Aplastic anemia in an HIV infected child.

Hematologic manifestations of HIV in children are common and include anemia, neutropenia, lymphocytopenia, thrombocytopenia that may occur due to many reasons. However, aplastic anemia due to HIV infection is rare and even more so in children. Though anemia is seen with advanced disease and associated with poor prognosis it is treated with various therapeutic modalities. Our patient with aplastic anemia due to HIV infection responded to antiretroviral therapy.

Von Hippel-Lindau disease: a case report.

Von Hippel Lindau (VHL) disease is a rare autosomal dominant condition manifested by central nervous system hemangioblastoma, retinal angiomas, cysts of pancreas, kidney and epididymis, pheochromocytomas and renal cell carcinoma. We present such a case in a 45 years old male patient.
