Osteosarcoma pleural effusion: A diagnostic challenge with some cytologic hints

alwin shared this article with you from Inoreader Osteosarcoma pleural effusion: A diagnostic challenge with some cytologic hints Via Diagnostic Cytopathology Abstract Pleural effusions can be the first manifestation, recurrence, or metastasis of small round cell sarcomas in children. The most common are Ewing sarcoma, neuroblastoma, and rhabdomyosarcoma. The cytomorphology is variable, the cells can be cohesive, single cells, small or large, morphologically mimicking lymphomas, carcinomas, melanomas, and mesothelioma depending on the sarcoma involved. Osteosarcomas are rare. Their rarity, variable histomorphologic features, immunophenotypic heterogeneity, being of osseous or extraosseous origin and focality of malignant osteoid matrix make their cytologic recognition a diagnostic challenge. They can be confused with small round cell sarcomas, may be misinterpreted as degenerative inflammatory cells, or masked by florid reactive mesothelial hyperplasia particularly in pleural effusions. However, attention to certain cytomorphologic features in smears and cellblock sections should raise suspicion. We report a case of a 9‐year‐old child who pr esented with cough, chest pain and breathing difficulty, left pleural effusion, a collapsed consolidated lower lung lobe, and a clinical impression of pneumonia. Pleural fluid cytology was initially reported as inflammatory effusion with florid reactive mesothelial hyperplasia. Tissue biopsy of the lung mass showed histomorphologic features consistent with osteosarcoma. A careful look at the cytology materials and cellblock sections showed helpful cytomorphologic features that were masked by florid reactive mesothelial cells and misinterpreted as degenerative inflammatory lymphocytes. An extracellular matrix was a helpful hint. Malignant pleural effusion secondary to osteosarcoma is rare. Cytologic examination may help reach the correct diagnosis if the smears and cellblock sections are carefully evaluated for certain helpful cytomorphologic features, particularly osteoid matrix.

Clear‐cell chondrosarcomas: Fine‐needle aspiration cytology, radiological findings, and patient demographics of a rare entity

alwin shared this article with you from Inoreader Clear‐cell chondrosarcomas: Fine‐needle aspiration cytology, radiological findings, and patient demographics of a rare entity Via Diagnostic Cytopathology Abstract Background Clear‐cell chondrosarcomas (CCCSs) constitute a very rare subtype of chondrosarcoma. CCCS may radiologically mimic chondroblastoma, and given the difference in surgical approach, it is important to distinguish these two entities preoperatively. Design Using the institutional digital records, we identified histologically verified CCCS between 1996 and 2013, where preoperative fine‐needle aspiration (FNA) cytology was available. Clinical characteristics were categorized and described, and FNAs were reviewed by a panel of senior cytopathologists. In addition, corresponding radiological imaging was reviewed by senior radiologists, and a literature review on CCCS and chondroblastoma was conducted. Results A total of seven CCCS FNAs were identified from six patients. The cytomorphology showed low to intermediate cellular smears of clusters and single round or oval tumor cells. Tumor cells had rounded (sometimes binucleated) nuclei with limited pleomorphism and rich vacuolated cytoplasm. Chondroid background matrix was always found. While CCCS patients had a significantly higher age at diagnosis compared to chondroblastoma, no age cut‐off would distinctly separate the two. Conclusions CCCS has distinguished cytomorphological features on FNA smears. CCCS should be considered as a possible differential diagnosis in adults (>25 years) with a radiological suspicion of chondroblastoma. Since radiology and patient age cannot conclusively distinguish CCCS from chondroblastoma, FNA may prove an important tool for correct preoperative diagnosis of CCCS. View on the web Inoreader.

Fine‐needle aspiration of parathyroid adenomas: Indications as a diagnostic approach

alwin shared this article with you from Inoreader Fine‐needle aspiration of parathyroid adenomas: Indications as a diagnostic approach Via Diagnostic Cytopathology Abstract Background We aimed to determine the indication of fine‐needle aspiration (FNA) for parathyroid adenoma (PA)‐suspected nodules and the cytological features of PA, and to discuss the ancillary techniques for diagnostic confirmation. Method Clinical, cytological, and histological examinations of 15 PA patients (4.0% of all PA resected patients) were conducted through FNA on 16 nodules. We also examined the cytological preparations of 10 follicular neoplasms (FNs) and 10 poorly differentiated thyroid carcinomas (PDTCs). Results FNA was performed to detect PA in nine (56.3%) nodules. The remaining seven (43.8%) nodules underwent FNA for lesions considered as thyroid nodules or lymph nodes. The levels of parathyroid hormone (PTH) in the aspiration needle washout fluid were observably high, except for that from one nodule with unsatisfactory FNA. Cytologically, the incidences of wedge pattern (86.7%) and salt and pepper chromatin (86.7%) in PAs were significantly higher than in FNs and PDTCs. In contrast, the appearance of colloid globules and nuclear grooves was less frequent than that of FNs and PDTCs. GATA‐3 expression was intense in all PAs that immunocytochemistry were performed. Histologically, capsular invasion and/or laceration, tumor seeding, granulation tissue, and fibrosis were observed. Conclusions When PA localization is unusual or inconclusive despite extensive imaging, FNA may be performed. We asserted that wedge pattern, salt and pepper chromatin, and the absence of colloid globules and nuclear grooves are diagnostic cytological indicators of PA rather than of FN or PDTC. We recommend PTH measurements using needle washout fluid for PA‐suspected nodules, and immunocytochemistry with the GATA‐3 antibody for cytologically PA‐suspected nodules. View on the web Inoreader.

Via pubmed j oral pathol med [... Related Articles The health-related quality of life and psychological profile in patients with oropharyngeal Pemphigus Vulgaris in complete clinical remission: a case-control study. J Oral Pathol Med. 2020 Dec 13;: Authors: Calabria E, Adamo D, Leuci S, Pecoraro G, Aria M, Coppola N, Mignogna MD Abstract BACKGROUND: Pemphigus Vulgaris (PV) is a severe autoimmune blistering disease which may affect the patient's health related quality of life (HR-QoL) and mood even during quiescent disease activity. We sought to evaluate HR-QoL, quality of sleep (QoS), anxiety and depression in oropharyngeal PV patients (OPV) in complete clinical remission on or off therapy (CCR-on, CCR-off). METHODS: 30 OPV patients and 30 healthy controls were enrolled. The Short Form 36 Health Survey Questionnaire (SF-36), Pittsburgh Sleep Quality Index (PSQI), Epworth Sleepiness Scale (ESS), Hamilton Rating Scale for Depression (HAM-D) and Hamilton Rating Scale for Anxiety (HAM-A) were administered. Descriptive statistics, including the Mann-Whitney U test and hierarchical multiple linear regression analysis, were used. RESULTS: The OPV patients had statistically lower scores in the majority of items of the SF-36 and higher scores in the PSQI, HAM-A and HAM-D than the healthy controls (p<0.004; p<0.001; and p<0.001 respectively). Nine (30%) of the OPV patients were poor sleepers (PSQI >5) with higher scores in the SF-36, HAM-A and HAM-D compared with the good sleepers (PSQI<5). No statistically significant difference was detected in the OPV group when comparing patients in CCR-on and CCR-off, or in consideration of the cumulative time of the disease duration (< 1, 1-3 and > 3 years). CONCLUSIONS: HR-QoL of OPV patients can be impaired even over periods of relatively well-being, therefore, clinicians should monitor periodically their HR-QoL, QoS and psychological profile in order to guide treatments also towards improving their HR-QoL.

J Oral Pathol Med. 2020 Dec 13;: Authors: Romano A, Di Stasio D, Lauritano D, Lajolo C, Fiori F, Gentile E, Lucchese A Abstract BACKGROUND: The introduction of Photodynamic therapy (PDT) in various branches of the dental field such as endodontics, implantology, periodontology, and restorative dentistry and oral medicine has become useful in recent decades. This systematic review presents an overview of the literature to evaluate the usefulness of topical PDT for the treatment of benign oral soft tissue lesions and to identify limitations in prior studies to improve PDT applications. METHODS: We performed a review of the literature using different search engines (PubMed, ISI Web of Science, and the Cochrane Library) employing MeSH terms such as "Photodynamic therapy" and "PDT" in conjunction with other terms. We utilized the Population, Intervention, Comparison, Outcomes, and Study design (PICOS) method to define our study eligibility criteria. RESULTS: Initial results were 1513. Finally, there were only 21 studies that met our selection criteria. We divided the 21 selected items into two groups: inflammatory diseases and infective diseases. CONCLUSIONS: Although topical PDT is an easy to perform and well-tolerated treatment and appears to be a valid method with promising results in the treatment of benign lesions of the oral cavity's soft tissues, further studies are needed to complete the current knowledge of this technique.

The aim of this study was to evaluate the clinicopathological profile and survival outcomes of pediatric patients affected by salivary gland tumors. MATERIALS AND METHODS: An extensive search was carried out using the MEDLINE/PubMed, EMBASE, Scopus databases, and grey literature. The risk of bias was available in all papers included. RESULTS: A total of 2,830 articles were initially retrieved with 54 remaining for data extraction, resulting in 2,937 cases. This comprised forty-five case series' and nine cohort studies. These tumors were slightly more prevalent in females (57.4%). The patients' age ranged from 0.3 to 19 years old, with a mean age of 13.3 years. Parotid was the most affected site (81.9%), and 99.2% of cases clinically exhibited a swelling. Presence of pain/tenderness was reported in 13.5% of the cases, with an average duration of 12.6 months for the appearance of symptoms. Most of the reported cases were malignant tumors (75.4%), with mucoepidermoid carcinoma the most common tumor of all tumors (44.8%), followed by pleomorphic adenoma (24.1%). Surgery alone was the leading treatment choice in 74.9% cases and the 5-year overall survival rate of patients was 93.1%. Patients with symptoms (P =0.001), local recurrence (P <0.001), metastasis (P <0.001), and those not undergoing surgery or surgery combined with radiotherapy (P <0.001) showed lower survival rates. CONCLUSION: The pediatric patients present a high frequency of malignant salivary neoplasms and a high overall survival rate.

Minimal Residual Disease Eradication by Azacitidine Maintenance in a Patient with Core-Binding Factor Acute Myeloid Leukemia

alwin shared this article with you from Inoreader Minimal Residual Disease Eradication by Azacitidine Maintenance in a Patient with Core-Binding Factor Acute Myeloid Leukemia Via Chemotherapy Although core-binding factor AML (CBF-AML) has a favorable outcome, disease relapses occur in up to 35% of patients. Minimal residual disease (MRD) monitoring is one of the important tools to enable us to identify patients at high risk of relapse. Real-time quantitative PCR allows MRD to be measured with high sensitivity in CBF-AML. If the patient with CBF-AML is in complete morphologic remission but MRD positive at the end of treatment, what to do for those is still uncertain. Preemptive intervention approaches such as allogeneic hematopoietic stem cell transplantation or intensive chemotherapy could be an option or another strategy might be just follow-up until overt relapse developed. Although using hypomethylating agents as a maintenance therapy has not been widely explored, here, we r... View on the web Inoreader. Take back control of your news feed.
