Intraparenchymal Hemorrhage Secondary to Rhino Orbitalcerebral Mucormycosis: A Case Report and Literature Review

 

Case study:

Intraparenchymal Hemorrhage Secondary to Rhino Orbitalcerebral Mucormycosis: A Case Report and Literature Review

St. Luke’s Medical Center, Institute for Neurosciences, Section of Adult Neurology, Capital Towers, E. Rodriguez Ave., Quezon City, Philippines

Mucormycosis is a rare invasive opportunistic fungal infection with high morbidity and mortality, with Intraparenchymal Hemorrhage (ICH) being one of the less common complications cited in available literature. In this case report, we present a case of a 65 year old Filipino diabetic male with non-small cell lung cancer and recent history of steroid use who presented with headache. This patient developed proptosis, chemosis, and purulent discharge from the right eye, and eventually had sudden onset decrease in sensorium on the 6th day of admission. CT scan showed findings of ICH on the right frontal and patient underwent craniotomy and evacuation of hematoma. Histopathology and culture findings confirmed the diagnosis of Rhino-orbital-cerebral mucormycosis. The patient was treated with Amphotericin B initially then shifted to voriconazole based on culture and sensitivity testing. The patient was managed in-patient for 3 months and eventually survived 18 months from the diagnosis.

To date, no case reports of ICH secondary to Rhino-orbital-cerebral mucormycosis are available in our locale. Additionally, patients from all previous published case reports all succumbed to the infection. This case demonstrates that a high index of suspicion and early workup is warranted in patients presenting with headache and having risk factors for mucormycosis. Early diagnosis and prompt treatment are keys towards achieving a good outcome in these patients.

Histopathological and Immunochemistry Characteristics of Gastrointestinal Stromal Tumors at Two Sub-Saharan Hospitals

 Bbosa BrianFrancis Basimbe*, Niyonzima Nixon and Emmanuel Othieno

Abstract

Introduction: Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal neoplasms of the gastrointestinal system. Histopathological and immunochemistry examination takes an important part in confirming the types of GISTs, to choose appropriate therapeutics for patients. Patients demographics, anatomic sites, histopathology and immunochemistry characteristics of GISTs are unknown in St Francis Hospital Nsambya (SFHN) and Uganda Cancer Institute (UCI).

Objectives: This study aimed to explore the demographics, anatomic sites, histopathological and immunochemical characteristics of GISTs in St Francis Nsambya Hospital and Uganda Cancer institute.

Methodology: A cross sectional study was conducted. The study population included patients with a histological diagnosis of GISTs who presented between 2018 to 2021 in both facilities. Clinical, pathological and immunochemistry data was collected and analyzed.

Results: A total of 146 records/blocks of patients were reviewed and out of these only Histology and immunochemistry was done on 81 blocks/ patients. Majority of the patients were aged 40 to 59years, (42%) and had a median age of 57 years with IQR (45-65). There was a male predominance of 51.9%. The commonest tumor site was the stomach, (81.5%). The commonest histological type was spindle cell (79%) followed by mixed (11.1%) then epithelioid 8 (9.9%). Most of cases in our study were benign (80.1%) and mitotic count ≤ 5/50 HPF in 71.6% cases. All cases with low mitotic rate were mostly benign with a p value of <0.0001.

Conclusion: We found GISTs were more common in male gender, stomach being the commonest site and 19% of GISTs were below 40 years. Spindle cell was the commonest histologic type and most of them were CKIT positive. Malignancy was correlated with non-spindle cell type and high mitotic rate.
