Well differentiated papillary mesothelioma of abdomen- a rare case with diagnostic dilemma

AbstractWell-differentiated papillary mesothelioma is a rare tumor occurring predominantly in the peritoneum of young women, a few with history of asbestos exposure. A 28-year-old woman presented with ascites and pain abdomen. Ultrasonography and computed tomography scan of the abdomen revealed a mass in the retroperitoneum measuring 15 cm × 12 cm. Histopathological examination along with immunohistochemistry (IHC) confirmed it to be a papillary mesothelioma in the peritoneum. It is difficult to differentiate from more common malignant mesothelioma and papillary adenocarcinoma, which also have poorer prognosis. The difficulty can be resolved by clinico-radiological correlation along with histopathological examination and IHC.

<p>Tuberculosis of the nose is so rare that it has become a forgotten entity among the clinicians. The clinicians fail to diagnose primary nasal TB as symptoms and signs of this specific nasal inflammation mimic other nonspecific nasal inflammatory conditions and therefore, its diagnosis and treatment is often delayed. We came across a case of primary nasal TB in a 65 years old female presented with complaints of nasal obstruction, epistaxis and anosmia since past 3 years. Anterior rhinoscopy showed friable nasal mass in both nasal cavities. Computed tomography scan showed heterogeneously enhancing soft tissue in nasal cavity with destruction of the nasal septum and hard palate. Histopathological examination and GeneXpert confirmed mycobacterium tuberculosis. The patient was put on antituberculous therapy.Nasal endoscopy and tissue biopsy play important role in diagnosis of the disease. GeneXpert test not only has good sensitivity and speciﬁcity for the diagnosis of EPTB but also perfectly ﬁts the requirements of the Indian health care setting.</p>

Abstract Background Excessive dynamic airway collapse (EDAC) is an uncommon cause of high airway pressure during mechanical ventilation. However, EDAC is not widely recognized by anesthesiologists, and therefore, it is often misdiagnosed as asthma. Case presentation A 70-year-old woman with a history of asthma received anesthesia with sevoflurane for a laparotomic cholecystectomy. Under general anesthesia, she developed wheezing, high inspiratory pressure, and a shark-fin waveform on capnography, which was interpreted as an asthma attack. However, treatment with a bronchodilator was ineffective. Bronchoscopy revealed the collapse of the trachea and main bronchi upon expiration. We reviewed the preoperative computed tomography scan and saw bulging of the posterior membrane into the airway lumen, leading to a diagnosis of EDAC. Conclusions Although both EDAC and bronchospasm present as similar symptoms, the treatments are different. Bronchoscopy proved useful for distinguishing between these two entities. Positive end-expiratory pressure should be applied and bronchodilators avoided in EDAC.

In this work, we discovered a new phenomenon—asymptomatic COVID-19 infection, or covert case, during the pandemic. All the 3 patients had a history of exposure, with no symptoms, and no abnormalities were found in computed tomography scan or lab tests. Except for case 2, the other patients’ severe acute respiratory syndrome coronavirus 2 (SARS-COV-2) nucleic acid tests were negative. But their anti-SARS-COV-2 nucleocapsid antibody showed a dynamic trend, consistent with the process of virus infection and clearance. A growing number of asymptomatic or covert cases need more attention. Lack of surveillance may lead to another outbreak. We hope to demonstrate our cases to attract the attention of governments or health authorities that covert cases should be the focus as well.

Isolated gall bladder tuberculosis (GBTB) is exceedingly rare even in an endemic region and is usually found as a GB mass in association with cholelithiasis. Confirmed preoperative diagnosis is very difficult, and most cases are diagnosed after cholecystectomy. We present a case of a 45-years-old woman who came with symptoms of chronic cholecystitis. Computed tomography scan revealed intraluminal gallbladder mass and cholelithiasis. The patient underwent open cholecystectomy and GBTB was diagnosed after histopathological examination. Histopathological examination should be done after all cholecystectomy operations. Faridpur Med. Coll. J. 2020;15(2): 106-107

Giant fibroids are known to arise from the uterus, and very rarely from the broad ligament. Large fibroids often undergo hyaline, cystic, and at times, red degeneration. In the present case, cystic degeneration with intervening septations in an adnexal mass raised the suspicion of ovarian neoplasm as the ovaries were not seen as separate from the lesion. The ultrasonographic and contrast-enhanced computed tomographic findings of this case were characteristic of ovarian neoplasm. The differential diagnosis included rare possibility of giant fibroid with cystic degeneration. The diagnosis was confirmed on histopathological examination. The patient underwent excision of the broad ligament fibroid, hysterectomy, and bilateral salpingo-oophorectomy. Magnetic resonance imaging has a role in the diagnosis of such lesions.

A 1.5-y-old spayed female Juliana pot-bellied pig was presented to the Purdue University Veterinary Teaching Hospital with a history of wasting and anorexia. Enlarged and partially mineralized lymph nodes were identified on radiographs and computed tomography scan. Generalized lymphadenomegaly and disseminated nodules in the lungs, liver, spleen, and kidneys were identified on postmortem examination. Histologic examination revealed caseonecrotic granulomas with numerous intracellular, acid-fast bacilli. Mycobacterium kansasii type II was identified as the etiologic agent by PCR amplification using universal Mycobacterium primers, direct sequencing of the PCR amplicon, and comparison to sequences in GenBank. We describe a case in a pot-bellied pig of mycobacteriosis caused by an atypical mycobacterial species and highlight the important role of laboratory testing in suspected cases of tuberculosis.

Amoebic colitis, caused by ingestion of water or food contaminated with the protozoan Entamoeba histolytica, can progress to a fulminant colitis. Computed tomography (CT) findings reported in the literature on this type of colitis are sparse. We present a 59-year-old male patient with a one-week history of progressive abdominal pain, abdominal distension and associated watery and bloody diarrhoea. A CT scan revealed deep ulcerations with submucosal and intramural tracking of contrast. Colonoscopy and biopsy confirmed a diagnosis of Amoebic colitis. The patient required a laparotomy and demised. Deep ulcerations with submucosal and intramural tracking of contrast on CT are diagnostic of fulminant amoebic colitis. Although not demonstrated at CT in this case, discontinuous bowel necrosis, omental wrapping (seen at laparotomy in our case) and neovascularisation of the bowel wall may be other features to look out for.

Primary tracheal synovial sarcoma is a rare malignancy and is usually found incidentally. Tumours can present with cough, dyspnoea, stridor and intermittent haemoptysis. The diagnosis is challenging because it is rare, and the symptoms may mimic other diseases of airway obstruction. A previously well 53-year-old man presented with an eight-month history of cough. He had a history of minimal haemoptysis a few months prior to presentation. Spirometry showed an obstructive pattern, and a computed tomography scan of the thorax revealed an intraluminal tracheal mass. This case highlights that a thorough initial evaluation, including spirometry, leads to an earlier diagnosis and successful treatment of this rare sarcoma.
