Hypertensive Intracerebral Hemorrhage in Young Patients From a Tertiary Care Center in Saudi Arabia: An Observational Study.

Objective: Young patients with intracerebral hemorrhage (ICH) make up a small but important subgroup of patients with ICH. This study investigated the clinical characteristics and outcomes of hypertensive ICH in very young (18-45 years) and young (46-55 years) patients.Methods: This was a retrospective study of patients aged 18-55 years with hypertensive ICH admitted to a hospital from April 2014 to April 2019. Clinical and radiologic features as well as long-term clinical outcomes were compared between 2 age groups: group 1 (18-45 years) and group 2 (46-55 years). Factors affecting the clinical outcome were investigated as well.Results: Of 63 patients with hypertensive ICH, 24 (38.1%) were in group 1 (mean ± SD age of 38 ± 4.6 years), and 39 (61.9%) were in group 2 (50 ± 2.5 years). The risk factor profile was similar except for diabetes, which was more prevalent in group 1 (odds ratio [OR] = 4.65; 95% CI, 1.4-15.2). Patients in group 1 had higher mean ± SD NIH Stroke Scale scores (15.7 ± 4.6, P = .044), had lower Glasgow Coma Scale (GCS) scores (OR = 3.33; 95% CI, 1.0-10.8), were at higher risk of intubation (OR = 2.79; 95% CI, 1.1-9.9), and had higher ICH volume (21 ± 18, P = .034). Worse clinical outcome was higher in group 1 (OR = 5.14; 95% CI, 1.0-26.1). Low GCS score, mean hematoma volume, and intraventricular extension were independently associated with worse outcome.Conclusions: Relatively young patients with hypertensive ICH have higher prevalence of diabetes and worse clinical outcome in comparison to older patients with hypertensive ICH. Such patients should be monitored and treated more aggressively.

Primary paranasal sinus hyalinizing clear cell carcinoma: a case report.

BACKGROUND: Hyalinizing clear cell carcinoma (HCCC) is a rare low-grade tumour of salivary glands that was first described as a distinct entity in 1994 by Milchgrub et al. EWSR1-ATF1 fusion was found to be specific for this tumour. The majority of the reported cases of HCCC arise from minor salivary glands within the oral cavity. Primary HCCC of the paranasal sinus is extremely uncommon. To our knowledge, only three cases have been reported in the English literature. Herein, we present a case of HCCC of the posterior ethmoid/maxillary sinus. CASE PRESENTATION: A 63-year-old lady who presented with a long history of epistaxis. CT scan revealed a destructive mass in the left ethmoid/posterior maxillary sinus extending to the nasal cavity. Surgical excision was done and microscopic evaluation showed a tumour composed mainly of nests of clear epithelial cells separated by fibrocellular and hyalinized septa with extensive bone destruction. The tumour cells expressed CK5/6, EMA and p63 immunohistochemically but were negative for S100 protein, PAX-8, RCC and CK7. Sinonasal renal cell-like adenocarcinomas, myoepithelial carcinoma and metastatic renal cell carcinoma were excluded by radiological and immunohistochemical studies. Fluorescence in situ hybridization analysis revealed an EWSR1 gene rearrangement. Postoperative radiation was administrated and the patient did not show recurrence or distant metastasis 4 months after the surgery. CONCLUSION: Head and neck region have many tumours that demonstrate clear cell changes on histology. Thus, the differential diagnosis for HCCC is wide. Awareness of this rare entity and the possibility of it is arising in unusual location is necessary. EWSR1-AFT1 fusion, a consistent finding in HCCC, can be used to confirm the diagnosis.
