“STUDY OF ENDOMETRIAL PATHOLOGY IN ABNORMAL UTERINE BLEEDING”

CONTEXT - Histopathological analysis of endometrial samples in various forms of abnormal uterine bleeding in adjunction with clinical history of patient to identify underlying cause of bleeding. This also helps in early diagnosis of premalignant and malignant lesions leading to their proper follow up and improved prognosis. AIMS - Histopathological analysis of causes of abnormal uterine bleeding with their clinical correlation. SETTINGS AND DESIGN -A prospective observational study MATERIAL AND METHODS - This study was done in department of pathology, GSVM medical college, Kanpur. This was a prospective study from year 2017-2018. A total of 300 cases were studied. Specimen received were xed in 10% formalin, processed and sections of 3-4 micron were prepared, stained with H and E. Histopathological examination was done. RESULTS - It was observed that the highest number of patients were between 41-50 years of age. (44.33%). Menorrhagia is the most common symptom accounting for 135 (45%) patients followed by metrorrhagia accounting for 135 (45%) patients and hypomenoorhea is the least common complaint. It was observed that there were signicantly higher number of patients with proliferative phase – 68 (22.67%) and in endometrial hyperplasia 35 (33.66%) patients. The least common cause were endometrial polyp, seen in 4 (1.33%) patients, gestational endometrium and gestational trophoblastic tumor accounted for 2 ( 0.67%) patients. In patients who presented with metrorrhagia, secretory phase endometrium was the most common histopathological nding accounting for 34.62% followed by proliferative phase. In cases of endometrial hyperplasia, 28 (80%) cases were simple cystic type, 5 ( 14.29%) cases were of simple endometrial hyperplasia with atypia and complex endometrial hyperplasia with atypia was found in 2(5.71%) cases. Among cases of endometrial hyperplasia, 28 (80%) cases were simple cystic type, 5 ( 14.29%) cases were of simple endometrial hyperplasia with atypia and complex endometrial hyperplasia with atypia was found in 2(5.71%) cases. Endometrial carcinoma is commonest complain in 51-60 years and >60 years age group. CONCLUSION - Histopathological analysis of AUB causes helps in identifying the cause and early diagnosis of premalignant and malignant cases.

Characteristics of Osteochondral Lesions of the Talus in Different Age Groups

We analyzed the characteristics of 112 consecutive patients who were operatively treated for osteochondral lesions of the talus from August 2014 to April 2019 in our hospital. The patients were divided into three age groups: young-adult (<40 years), middle-age (40–60 years) and old-age (>60 years). The basic clinical features, localization and size of the lesions, Hepple stage, and surgical procedures were compared among groups. Several significant differences were found on the characteristics of osteochondral lesions of the talus among age groups. There were more female patients in the old-age group (p<0.01), and old patients had a longer duration of symptoms (p<0.05). The OLTs in middle- and old-age patients were mostly located in the medial part of the talus with larger depth (p<0.01). Hepple stage 5, the cystic type, was very common in the old-age group (p<0.01). With regard to surgical procedures, more osteochondral autograft transplantations were applied in the old-age group (p<0.01). Female and deep medial talar subchondral cyst is the typical characteristics of patients over 60 years old. Age is an important factor that must be considered when choosing surgery procedure for patients with osteochondral lesions of the talus.

P14.42 Diagnostic challenges of infratentorial hemangioblastomas: improvement of current radiological classification scheme

BACKGROUND Hemangioblastomas (HBMs) are known to exhibit very typical radiological features and thus classified by well-established radiological classification scheme. However, after we have experienced unusual cases in which current radiological classification system was not enough to categorize them, we reviewed our series of infratentorial HBMs in order not only to evaluate the relevance of current classification scheme, but also to possibly improve it. Also, we added descriptions on several cases with unusual radiological magnetic resonance imaging (MRI) findings in which differential diagnosis was challenging. MATERIAL AND METHODS We retrospectively reviewed preoperative MRI of 118 patients with pathologically diagnosed infratentorial HBMs at our institution between 2002 and 2015. Total 128 tumors were included to this study and classified into four categories based on the presence and nature of cystic components: extratumoral cystic (Type Ce, classical cystic with a mural nodule), intratumoral cystic (Type Ci), mixed cystic (Type Cm), and solid (Type S). The association with von Hippel-Lindau (VHL) disease was also investigated. RESULTS In 118 patients (65 male and 53 female), 79 (66.9%) had solitary HBMs and 39 (33.1%) were diagnosed with VHL disease. Type Ce with typical radiological findings was the most prevalent type of HBM (63.3%), followed by Type S (21.1%). HBMs with intratumoral cysts were uncommon (Type Ci, 11.7%) and mixed extratumoral and intratumoral cysts (Type Cm) accounted for only 3.9%. No intergroup differences were observed in the proportions of each subtype between the solitary and VHL disease-associated HBMs. CONCLUSION Radiological features of HBMs are usually typical thus preoperative presumption is not difficult in majority of cases. Improved radiological classification scheme is more practical because it does not only help surgeons determine whether the cystic wall should be removed or not, but also covers cases with atypical radiological presentations. For solid and extraparenchymal HBMs, differential diagnosis is more difficult as well as very critical as surgical removal is often very challenging.

Meconium pseudocyst revisited

Meconium peritonitis is defined as a sterile chemical or foreign-body peritonitis that is caused by escape of meconium from the intestinal tract into the peritoneal cavity during the fetal or perinatal period. Although meconium peritonitis is indicative of intrauterine perforation of the intestine, it may occur as early as the 4th to 6th month of INTRA NATAL life and as late as several hours after birth. It can be classified into three pathological variations: fibro-adhesive; cystic and generalized. The cystic type has a meconium filled pseudocyst that may rupture in the peritoneal cavity. Intra-abdominal calcification is pathognomonic for the diagnosis. Here, author reported a classical case of meconium peritonitis with pseudocyst formation, which was treated successfully conservatively.

Ultrasonography and fine-needle aspiration biopsy in the diagnosis of a cystic type of thyroid papillary cancer

Background: Cystic type of thyroid papillary carcinoma is a rare independent disease of this organ. Its prevalence among papillary carcinomas is from 2.5 to 6%.Aim: To identify ultrasonographic features of the cystic form of papillary carcinoma for the differential diagnosis of solitary liquid neoplasms of the thyroid and to elaborate an optimal technique for its fine-needle aspiration biopsy.Materials and methods: We retrospectively analyzed the data on the diagnosis and treatment of 29 patients with the cystic type of thyroid papillary carcinoma (26 women, 3 men, mean age 52 years). The instrumental diagnosis was based on a comprehensive ultrasonography and fine-needle aspiration biopsy.Results: We identified the following ultrasonographic characteristics of “potentially malignant” cystic nodules of the thyroid: the wall thickness of 2 to 3 mm with marginal tissue components of various size (from 10 mm to 3 cm in diameter) and microcalcinates; presence of focal blood supply by color Doppler mapping; homogeneity and low echogenicity of the liquid component. Conclusion: The right interpretation of the ultrasonographic results and adequately performed fine-needle aspiration biopsy help to verify the diagnosis of thyroid carcinoma and to avoid mistake in the treatment of this patient category.

Long-term evaluation of Primary Osteochondral Autograft Transfer System (OATS) for large cystic type osteochondral lesion of talus

Category: Ankle Introduction/Purpose: Osteochondral lesions of talus (OLTs) are often treated primarily by fragment excision, abrasion, drilling, or microfracture. However, OLT accompanying with large cyst has been challenged to yield good outcome nevertheless of many surgical options. Recent study showed significant high failure rate of arthroscopic marrow stimulation treatment larger than 150mm2. The current study is to investigate the outcome of the primary osteochondral autograft transfer system (OATS) for large cystic type OLT (>150mm2). Methods: This retrospective analysis included 19 talus (19 patients) with diagnosed large cystic type OLT (>150mm2) who received primary OATS between September 2009 and March 2013. Defect size area was measured on magnetic resonance imaging (MRI) by the ellipse formula from coronal and sagittal length. The patients completed the visual analog scale (VAS) and the American Orthopaedic Foot & Ankle Society (AOFAS) score preoperatively and at follow-up. Plain radiographs were used to show the improvement of radiolucency postoperatively. Results: The mean follow up period was 83.9 months (57 – 99) and the average defect size area was 169.4 mm2 (151.3 – 392.6). The Mean VAS score decreased from 6.95 preoperatively to 2.6 postoperatively. Average AOFAS score improved from 66.8 preoperatively to 88.7 postoperatively. Eighty percent of patients rated their result excellent or good. The radiolucent area of the cysts disappeared on the plain radiographs in all cases. Conclusion: Long-term clinical results of primary OATS in large cystic type OLT showed good outcomes and patients could significantly benefit from this surgery.

Histogenesis and classification of diffuse and cystic uterine adenomyosis

Purpose: Recently, focal adenomyosis was classified into three subtypes according to magnetic resonance imaging findings: connected to the endometrium (subtype I), connected to the perimetrium (subtype II), and not connected to either the endometrium or the perimetrium (subtype III). However, diffuse adenomyosis and cystic adenomyosis have not been investigated. We attempted to classify diffuse-type adenomyosis and cystic-type adenomyosis according to magnetic resonance imaging findings and verified the validity of the previous classification of focal adenomyosis. Methods: A total of 1504 cases of adenomyosis (focal, n = 1093; nodular, n = 15; diffuse, n = 383; cystic, n = 13) shown in magnetic resonance imaging findings of patients who underwent conservative surgical treatment from 2002 to 2016 at our hospital were reviewed according to the criteria of Kishi. Results: Of the 383 patients with diffuse adenomyosis, 272 (70.8%) were classified as subtype I, while all cases of cystic-type adenomyosis developed in the lateral wall of the uterus were classified as subtype III. Conclusion: Our findings indicate that diffuse adenomyosis develops from the same mechanism as focal adenomyosis subtype I. In addition, we consider that subtype III has greater relationship with cystic adenomyosis than the other types.
