An Unusual Solitary Fibrous Tumor of the Ischiorectal Region.

Solitary fibrous tumors (SFTs) are rare fibroblastic/myofibroblastic proliferations that occur in a wide range of anatomical sites. These tumors have nonspecific clinical presentations often with unpredictable biological behavior. SFTs can be slow growing low-risk tumors or rapidly growing high-risk tumors. They show a wide variety of histological features and typically are characterized by NAB2-STAT6 fusion. SFTs of the ischiorectal fossa are rare, with few studies reported in the literature to date. Here, we report a 90-year-old male who had a road traffic accident in October 2018. A pelvic computed tomography (CT) revealed a mass measuring 3.5 × 2.5 cm in the right ischiorectal fossa. Histopathology of the CT-guided biopsies confirmed the diagnosis of low-grade SFT. No surgical intervention was needed since the patient was asymptomatic. In January 2022, a follow-up CT showed a gradual increase in tumor size (5 × 3.5 × 3 cm), but not infiltrating the surrounding structures. However, the patient complained of constipation, which warranted a surgical excision of the mass. Subsequently, immunohistological examination reconfirmed the diagnosis of low-risk SFT. Here, we discussed the clinicopathological features of the case and the relevant literature about pelvic SFTs. In conclusion, SFTs should be considered in the differential diagnosis of any ischiorectal mass. It is recommended that tissue samples be obtained, and immunohistology should be performed.

Primary Basidiobolomycosis of the Cecum in Immunocompetent Patients: Two Case Reports.

Colonic basidiobolomycosis is a rare fungal infection caused by Basidiobolus ranarum. Primary cecal basidiobolomycosis is an exceptionally rare condition. The study describes two cases of primary basidiobolomycosis of the cecum in immunocompetent male and female patients (one each). The patients presented with fever, abdominal pain, weight loss, eosinophilia, and high erythrocyte sedimentation rates. Computed tomography revealed wall thickening and mass lesions involving the cecum, suggesting malignancy. Right hemicolectomies were performed to relieve the intestinal obstruction. On microscopy, there were destructive, transmural eosinophil-rich pyogranulomatous reactions with thin-walled, pauci-septated fungal elements surrounded by Splendore-Hoeppli bodies. The patients received antifungal drugs, with no evidence of dissemination or recurrence on follow-up. Primary cecal basidiobolomycosis in immunocompetent hosts is a rare occurrence. It oftentimes clinically masquerades malignant neoplasms and therefore its identification mandates its inclusion in the differential diagnosis of a colonic mass, equally both on the part of the clinicians and pathologists.

A comparison between transabdominal ultrasonographic and cystourethroscopy findings in adult Sudanese patients presenting with haematuria.

PURPOSE: Gross and microscopic haematuria both are a common cause of referral to urology clinics. It has a wide spectrum of differential. In many occasions, it is a presentation of underlining serious urological problems. Evaluation of gross and significant microscopic haematuria is of paramount importance. This study was conducted to assess and compare the findings and diagnostic competency of transabdominal ultrasonography (US) versus cystourethroscopy in patients with haematuria of lower urinary tract origin. METHODS: Prospective hospital-based study done at Ibn Sina Specialized and Omdurman Military Hospitals from June 2012 to March 2013. The study included 109 patients. Structured questionnaires were used to gather data from patients. All patients were evaluated by transabdominal US before cystourethroscopy examination. RESULTS: One hundred and nine patients were studied. Patients' mean (SD) age was 57.9 (18.8) years. Fifty-four patients (49.5 %) presented with macroscopic haematuria, while 55 patients presented with microscopic haematuria. The sensitivity and specificity of the US in detecting prostate enlargement, vesical stones, bladder wall tumour, cystitis and schistosomiasis were [(84, 80 %); (82.6, 97.7 %); (64.7, 92.1 %); (15.3, 96.8 %); and (15.3, 98.9 %)], respectively, as compared to cystoscopic finding as the gold standard. CONCLUSIONS: Ultrasonography is accepted only as a first-line imaging tool for evaluation of haematuria in poor settings, but cannot replace or became as good as cystoscopy, which remains the gold standard.
