OBJECTIVE
The research aimed to isolate, adapt to cell culture, and characterize the lumpy skin disease virus (LSDV) from clinically infected cattle in Bangladesh.
MATERIALS AND METHODS
From September 2019 to June 2020, 37 skin nodules and skin swabs were aseptically collected from afflicted cattle in the outbreak regions of Jhenaidah and Kishoreganj in Bangladesh. The LSDV was isolated from embryonated specific pathogen-free (SPF) chicken eggs along the chorioallantoic membrane (CAM) route and the Vero cell line after several blind passages. The viral attachment protein was targeted for molecular detection using polymerase chain reactions (PCR). For phylogenetic analysis, PCR-positive products were partially sequenced.
RESULTS
The virus was evident in the cell line, showed cytopathic effects after the 13 blind passage, and on the CAM of SPF chicken eggs, exhibited thickening of the CAM with pock-like lesions. A total of 12 samples (32.43%) tested positive for LSDV by PCR. Phylogenetic analysis of the present isolates (accession numbers MN792649 and MN792650) revealed 100% similarity with strains from India (MN295064), Kenya (AF325528, MN072619, KX683219), Greece (KY829023), Serbia (KY702007), and Kazakhstan (MN642592); moreover, 99.43% to 100% similarity to the sheep pox virus.
CONCLUSION
Partially sequenced LSDV was developed as a vaccine seed and was first isolated in Bangladesh and characterized at the molecular level.

Anaplastic thyroid carcinoma is a rare and aggressive form of thyroid cancer that has a poor prognosis and a high mortality rate. It is characterized by rapid growth and invasion of nearby tissues. It typically presents as a rapidly growing goiter or nodule that is firm to the touch and firmly attached to the underlying structures. Case reports of unusual presentations of anaplastic thyroid carcinoma have been reported. The presentation of anaplastic thyroid carcinoma mimicking cervical tuberculosis is very unusual. We reported a case of a 65-year-old patient who had a left cervical swelling that had been evolving for 4 months, causing dysphagia. Initial imaging showed a necrotic mass in the left lobe of the thyroid, communicating with a second necrotic mass in the subcutaneous tissue that was fistulized to the skin and suggesting cervical tuberculosis. The mass was incised with pus and whitish material resembling caseous tuberculosis was discharged. Acid-fast bacilli (AFB) Polymerase chain reaction (PCR) was negative and biopsy revealed a nonspecific granulomatous lesion. Due to the growth of the mass and the presence of a permeation nodule, a second biopsy was performed, revealing anaplastic thyroid carcinoma. The patient was referred for radiochemotherapy due to tumor inoperability.

Review
The fusariosis is an opportunistic mycosis caused by Fusarium spp. Its clinical presentation depends on the immunological status of the host, especially in patients with hematooncological diseases, whose manifestations vary from localized to invasive fungal infections. Skin or blood culture helps to guide combined antifungal treatment with amphotericin B and voriconazole. Here, we present 13 cases in a period of eleven years of patients with cancer who developed disseminated fusariosis and their outcomes, together with a review of the related literature. In this series of cases, mortality was 61.5 % (8/13), despite the use of the antifungal. Out of the 13 cases, 11 had hematological neoplasia and 2 solid neoplasia. The most determinant risk factor was profound neutropenia. Skin involvement and positive blood cultures in most cases allowed combined treatment prescription. Persistent febrile neutropenia associated with skin lesions, onychomycosis, nodules, or lung masses lead to suspicion of Fusarium spp. fungal invasive infection. The aim of this series of cases is to remind healthcare professionals that oncological patients with deep and persistent febrile neutropenia can develop fusariosis.

Skin metastasis is a relatively rare complication of pulmonary carcinoma. The clinical features are varied and can present as sclerodermoid, bullous, erysipeloid, or alopecia, but they can also manifest as skin nodules, as in our case. We report a case of a 66-year-old man exhibiting this unusual manifestation. This case report aims to review and describe different findings in ultrasound, CT and pathology, to establish the diagnosis of pulmonary carcinoma manifested by skin metastasis.

Meta-Analysis
OBJECTIVE
The current body of evidence lacks clarity regarding the comparative efficacy and safety of radiofrequency ablation (RFA) and microwave ablation (MWA) as minimally invasive treatments for benign thyroid nodules. The primary objective of this study is to clarify these concerns.
MATERIALS AND METHODS
A comprehensive search was conducted using the Cochrane Library, Scopus, Europe PMC, and Medline databases until October 10th, 2023, using a combination of relevant keywords. This study incorporated literature that compared RFA and MWA for benign thyroid nodules. The primary outcome was the volume reduction ratio (VRR) from baseline to follow-up. Secondary outcomes were symptom score, cosmetic score, ablation time, major complications rate, hemorrhage, hoarseness, skin burn, cough, and sympathetic nerve injury. We used Risk of Bias in Non-randomized Studies - of Interventions (ROBINS-I) tool to assess the risk of bias in the included studies. We employed random effects models to analyze the standardized mean difference (SMD) and odds ratio for the presentation of outcomes.
RESULTS
Nine studies with 2707 nodules were included. The results of our meta-analysis indicated similar efficacy between RFA and MWA in terms of VRR during the 1 (SMD 0.06; 95% confidence interval [CI]: -0.13 to 0.26; = 0.52) and 3 (SMD 0.11; 95% CI: -0.03 to 0.25; = 0.12) months of follow-up. VRR was significantly higher in RFA than in MWA at the 6 (SMD 0.25; 95% CI: 0.06-0.43; = 0.008) and 12 month of follow-up (SMD 0.38; 95% CI: 0.17 to 0.59; < 0.001). There were no significant differences between RFA and MWA in symptom scores, cosmetic scores, or the incidence of complications, including hemorrhage, hoarseness, skin burn, cough, and sympathetic nerve injury.
CONCLUSION
RFA showed a higher VRR than MWA at 6 and 12-month follow-ups, with a comparable safety profile.

INTRODUCTION
Cutaneous metastasis of urothelial carcinoma is a rare occurrence, accounting for a small percentage of skin metastases in cancer patients. This case presentation highlights the importance of considering cutaneous metastasis in patients with a history of urologic malignancy presenting with new dermal nodules.
CASE PRESENTATION
A 79-year-old male with a history of papillary urothelial carcinoma of the bladder and metastasis to the rectum presented with a painful and pruritic rash in the right inguinal region. Physical examination revealed firm papulonodules forming confluent, hyperpigmented to violaceous plaques. A punch biopsy confirmed the diagnosis of cutaneous metastasis of urothelial carcinoma based on histopathological and immunohistochemical findings.
CONCLUSION
While cutaneous metastasis is uncommon in urothelial carcinoma, early recognition and diagnosis are crucial in guiding patient management and setting realistic expectations regarding prognosis. Timely identification of cutaneous lesions can help facilitate appropriate treatment decisions and discussions of goals of care.

Review
Hidradenitis suppurativa (HS) is a chronic skin disorder characterized by nodules, comedones, and sinus tracts that often leave prominent scarring. In recent years, non-invasive imaging techniques have been used to assess the inflammatory activity, vascularization, and treatment response of lesions. Specifically, fluorine-18 fluorodeoxyglucose positron emission tomography/computed tomography (FDG-PET/CT) scans may aid in identifying systemic inflammation in patients with HS, improving diagnosis. Inflamed hypermetabolic tissues exhibit a greater uptake of FDG due to increased glucose uptake and vascularity. A systematic review was conducted to summarize the utility of nuclear imaging techniques in the diagnosis and treatment follow-up of HS. PubMed, Scopus, and ScienceDirect databases were utilized for relevant articles discussing the utility of PET scans in managing HS. A total of 51 citations were identified in the initial search. Following the review of titles, abstracts, and duplicates, 43 articles were excluded, leaving a total of eight articles for analysis. Data were extracted from each article, encompassing the number of patients, imaging techniques employed, and final results. An analysis of the data demonstrated that FDG-PET showed evidence of identifying subclinical lesions of the disease, improving the visualization of HS, and providing an objective method of assessing severity.

Review
Systemic sclerosis, also referred to as scleroderma, is a chronic autoimmune disease that affects both internal organs and the skin. Systemic sclerosis predominantly affects female patients and can coexist with other disorders, including those affecting the thyroid gland. Common symptoms such as fatigue and weight changes can be attributed to either systemic sclerosis or thyroid disease. In this comprehensive review, an extensive analysis is conducted using research from 2002 to 2022, sourced from PubMed. The main focus of this exploration is to understand the intricate relationship between thyroid disorders and systemic sclerosis. We obtained these results by analyzing a number of 32285 patients included in 21 original studies. The existing evidence suggests that there is a higher incidence of elevated TSH levels and hypothyroidism in patients with systemic sclerosis, particularly in females, compared to the general population. This remains true even when comparing patients from iodine-deficient regions. Additionally, there is an increased occurrence of hyperthyroidism in the context of systemic sclerosis, which negatively impacts the prognosis of these patients. Furthermore, thyroid antibodies, predominantly anti-thyroid peroxidase (anti-TPO) antibodies, and autoimmune disorders are more commonly observed in individuals with systemic sclerosis. Although thyroid nodules are not specifically linked to the disease, when considering thyroid volume, it is observed that the thyroid gland in systemic sclerosis patients has a decreased volume, possibly due to fibrosis. Conversely, other studies have revealed that patients without autoimmune thyroid diseases (AITDs) are more likely to have a history of digital ulcers, pulmonary fibrosis detected by computed tomography scan, and a requirement for immunosuppressive medication. The majority of the studies did not establish a connection between thyroid disease in these patients and the occurrence of the limited or diffuse forms of systemic sclerosis, as well as the presence of digital ulcers, calcinosis, pulmonary arterial hypertension, scleroderma renal crisis, Raynaud phenomenon, and various other clinical manifestations.

Granulomatous rosacea is a chronic inflammatory skin disease. We present the case of a 30-year-old woman with a three-month history of erythematous monomorphic papules and nodules on the cheeks and forehead. Histopathological examinations revealed tuberculoid granulomas with multinucleated giant cells. Granulomatous rosacea should be differentiated from other similar granulomatous skin diseases such as cutaneous sarcoidosis and Lupus miliaris disseminates faciei.

Review
Buruli ulcer (BU), a neglected tropical disease (NTD), is an infection of the skin and subcutaneous tissue caused by . The disease has been documented in many South American, Asian, and Western Pacific countries and is widespread throughout much of Africa, especially in West and Central Africa. In rural areas with scarce medical care, BU is a devastating disease that can leave patients permanently disabled and socially stigmatized. is thought to produce a mycolactone toxin, which results in necrosis of the afflicted tissue and may be involved in the etiology of BU. Initially, patients may notice a painless nodule or plaque on their skin; as the disease progresses, however, it may spread to other parts of the body, including the muscles and bones. Clinical signs, microbial culture, and histological analysis of afflicted tissue all contribute to a diagnosis of BU. Though antibiotic treatment and surgical removal of infected tissue are necessary for BU management, plant-derived medicine could be an alternative in areas with limited access to conventional medicine. Herein we reviewed the geographical distribution, socioeconomic, risk factors, diagnosis, biology and ecology of the pathogen. Complex environmental, socioeconomic, and genetic factors that influence BU are discussed. Further, our review highlights future research areas needed to develop strategies to manage the disease through the use of indigenous African plants.
