Background: Abnormal uterine bleeding (AUB) is the most common health issue in women, defined as any bleeding pattern that differs in frequency, duration, and amount. Endometrial sampling and its histopathological examination is the first-line test in patients presenting with AUB. The aim of this study was to analyze the histopathological patterns of endometrium in women with AUB and to find the predominant histopathologic pattern in the different age groups of women with AUB.

Background: Lichenoid dermatitis is a very common dermatological condition and is defined by features of basal cell damage and a dense band-like infiltration at the dermo-epidermal junction. There is a wide range of lesions included under this and the prototype lesion is Lichen Planus. Aims and Objectives: The aims of this study were to study the histopathological spectrum of the conditions with lichenoid tissue reaction and to find clinicopathological concordance of the lichenoid lesions. Materials and Methods: A retrospective study was conducted in a tertiary care center, where all the skin biopsy cases diagnosed clinically and/or histologically as lichenoid dermatitis for 2 years (2018–2019) were included in the study. Demographic details, clinical diagnosis, histological diagnosis, and the different histological features were collected from the respective case sheets and biopsy reports and entered in an excel worksheet. Frequency and percentages were used to represent the data. Results: A total of 47 cases were clinically diagnosed as lichenoid dermatitis, of which 38 cases showed concordance between clinical and histopathological diagnosis. Nine cases showed discordance between clinical and histopathological diagnosis and were categorized as lesions without lichenoid features. Seven cases were diagnosed as lichenoid dermatitis only on the histopathological study with an absence of such a differential diagnosis clinically. Out of the total 45 cases diagnosed as lichenoid dermatitis, 27 were lichen planus, five were lichen planus pigmentosus, four were hypertrophic lichen planus, three were lichenoid dermatitis, and two cases each of lichen planopilaris, lichen keratosis, and lichen sclerosis. Lichenoid dermatitis was seen commonly among the 41–50 years age group. Females were more commonly affected than males. Conclusion: Lichen planus is the prototype lesion among the lichenoid dermatitides. Definitive diagnosis of the specific entity among the lichenoid lesions is important as decision-making regarding the treatment modality and prognosis of the patient depends on it. Histopathological examination is vital for the definitive diagnosis, along with clinical correlation which concludes that clinicopathological correlation is the key.

Background: The connective tissue around the blood vessels in the body (except cerebral vessels) is called perivascular adipose tissue (PVAT). Whenever there is a vascular pathology, PVAT increases in volume and becomes dysfunctional. This change promotes dedifferentiation of adipocytes. PVAT inflammation (PVATi) starts secreting anti-vasodilation and pro-inflammatory substance, leading to infiltration of inflammatory immune cells, endothelial dysfunction which initiates atherosclerosis followed by stenosis. It is now recognized that PVATi plays an important role in many vascular pathologies. Aims and Objectives: The objectives of the study were (1) to estimate the prevalence of coronary PVATi in an autopsy case, (2) to determine the coronary atherosclerotic changes and cardiac changes associated with PVATi, and (3) to correlate the association of PVATi with age and sex. Materials and Methods: Autopsy-based retrospective study done for a period of 1 year. From the autopsy requisition form, details such as age, gender, cause of death (COD), and gross findings of the organs were noted. The left coronary artery, right coronary artery, left anterior descending artery, left circumflex artery, and myocardium slides were reviewed microscopically to note the presence of PVATi, type of inflammatory infiltrate, atherosclerotic changes, percentage of stenosis, and associated cardiac changes. Range, frequencies, percentage, mean, standard deviation, and P-value were calculated. P<0.05 was taken as statistically significant. Results: Fifty-two cases showed PVATi among 400 autopsy cases performed during the period of 1 year. Forty-two cases were from males and 10 cases were from female. The most common COD noted was sudden death following chest pain. Ten cases showed PVATi involving major branches of the coronary artery. Thirty-six cases showed hypertrophic changes in myocardium. Acute myocardial infarction (MI) and old healed MI were noted in 7 and 23 cases, respectively. Conclusion: PVATi of coronary arteries has significant association with atherosclerosis and sudden death cardiac death.
