IntroductionAppendicular mucocele is a rare well-described clinico-pathological occurrence. It denotes an obstructive dilatation of the appendicular lumen by mucinous secretions.Case reportA 60-year-old patient presented with right lower abdominal pain and nausea for 2 years. Abdominal CT scan suggested a diagnosis of a appendicular mucocele. Following informed consent, surgical exploration revealed a cystic mass arising from the body of the appendix with inflamed walls with no evidence of perforation. Simple appendectomy was performed as the caecum and the mesenteric nodes were free of pathological involvement. The final diagnosis of mucinous cystadenoma was confirmed by histopathology. Postoperative course was uneventful. The patient was in good health during a four years regular follow-up.DiscussionAppendicular mucocele is a rare disease with vague symptoms. Abdominal imaging is an important diagnostic tool, but histopathology is the standard for definitive diagnosis. Surgery for benign appendicular mucoceles has an excellent long-term prognosis.

HighlightsIdiopathic pneumoperitoneum is a rare clinical entity that is challenging to identify and manage.Unneccessary surgical intervention in idiopathic pneumoperitoneum can lead to significant morbidity and even mortality.Conservative treatment with close observation is optimal if no peritonitis or radiological evidence of perforation.Contrast-enhanced CT may help exclude gastrointestinal perforation with 86% accuracy and thus help avoid unnecessary surgical intervention.

Background: Mycetoma is a chronic, progressive, disfiguring, and destructive disease. It caused by a variety of microorganisms including fungi and higher bacteria. It is primarily an infection of the skin and soft tissue, most frequently affecting the lower extremity and the hand and spread through fascial planes and lymphatics. Methods: Current medical and surgical management are still inadequate and the recurrence rate is high with severe disabilities. Results: This review describes some reconstructive techniques that were performed to address essential aspects with regard to mycetoma surgical management that include coverage of large skin and soft-tissue defects left after local excisions, enhancing the rate of chronic mycetoma wound healing, and preservation or restoration of functional status of the affected limbs. Conclusion: These applied techniques—which had acceptable preliminary outcome—have to be considered by the surgeons dealing with mycetoma to improve the functional and cosmetic outcomes and to minimize tremendous morbidities and disabilities that are associated with this neglected disease.

<b><i>Introduction:</i></b> Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the viral agent responsible for the coronavirus disease of 2019. The disease is primarily a respiratory illness; however, multisystem involvement is not uncommon. The infection is reported to be more severe in patients with multiple comorbidities and immunocompromised patients. Patients with hematological malignancies are immunocompromised and prone to develop severe SARS-CoV-2 infection. The SARS-CoV-2 had developed several mutations that resulted in different strains with different virulence and different degree of protection by vaccination or prior infection. The Omicron variant is reported to cause mild illness; however, the effect on patients with hematological malignancies like myeloproliferative neoplasms (MPNs) is not clear. We present patients with MPNs who had infection with the Omicron variant of the SARS-CoV-2 and their outcomes. <b><i>Methods:</i></b> Retrospective data from the National Center for Cancer Care and Research records from December 20, 2021, to January 30, 2022. Participants were adults over the age of 18 years with Omicron infection who had been diagnosed with Philadelphia-negative MPNs, essential thrombocythemia, polycythemia vera (PV), and primary myelofibrosis according to the 2008/2016 WHO classification for MPN. <b><i>Results:</i></b> Twenty-two patients with Philadelphia-negative MPN had Omicron infection. All patients had a mild disease according to the WHO classification of COVID-19 severity. Most of the patients had medical comorbidities, with hypertension being the most common comorbidity. However, only one patient with PV required hospitalization. <b><i>Discussion/Conclusions:</i></b> In patients with Philadelphia-negative MPN, the Omicron variant of SARS-CoV-2 usually results in mild infection.

We report a rare case of primary hepatic lymphoma (PHL) in a hepatitis B virus- (HBV-) infected young female patient who presented with right upper abdominal pain, nausea, and vomiting for a few days. The preoperative diagnosis was difficult due to the rarity of the disease and the presence of a solitary hypodense mass in the left lobe of the liver on contrast-enhanced computed tomography (CT) scan with a normal alpha-fetoprotein (AFP) and negative cytology. She underwent an uneventful extended left hemihepatectomy, and the surgical biopsy revealed a PHL—of diffuse large B-cell lymphoma (DLBCL) type—with negative resection margins. She received adjuvant combination chemotherapy and remained disease-free with normal serial radiology over a 2-year follow-up period.
