Presented is a case report of spontaneous rupture of the renal parenchyma associated with urinoma. A 3-year-old boy had a history of transient gross hematuria followed by sudden onset of left flank pain. Echograms and computed tomographic (CT) scan revealed a left hydronephrotic kidney with perirenal urinoma which had a cyclic change in size corresponding to the pain. Left retrograde pyelogram showed stenosis of the ureteropelvic junction without extravasation of contrast medium. A pin-hole tear was detected in the middle of the left renal parenchyma on exploratory surgery. Left pyeloplasty and retroperitoneal drainage were performed. The postoperative course was satisfactory. Spontaneous rupture of the renal parenchyma, which is frequently caused by renal tumor, vascular disease and/or infection, seems to be seldom caused by increased renal intrapelvic pressure as in rupture of the renal pelvis.

Perinephric abscess commonly arises from rupture of an intrarenal abscess into the perinephric space. It rarely results from gastrointestinal pathology. We report two pediatric patients with retrocecal appendicitis that presented with perinephric abscess. A 3-year-old girl presented with high fever and right flank pain for more than 1 week. Ultrasonography showed a right perinephric fluid collection with normal renal parenchyma and collecting system. A perinephric abscess extending from a ruptured retrocecal appendix was diagnosed by abdominal computed tomographic (CT) scan. Her hospital course was complicated with empyema, peritonitis, and pericardial effusion. A 6-year-old girl had lower abdominal pain for 3 days and high fever on the day of admission. Ultrasonography showed a right perinephric abscess with a normal renal contour and a fecalith in the enlarged appendix in the right lower quadrant of the abdomen. Appendectomy and drainage of the perinephric abscess were performed in both cases. We suggest that a ruptured retrocecal appendix must be considered in cases of perinephric abscess, especially in patients with gas bubbles in the abscess and a normal urogenital appearance. Ultrasonography and abdominal CT scan are the preferred diagnostic tools. Prolonged antibiotics and drainage of the abscess are mandatory to decrease morbidity and mortality.

Glomangiomas are a subset of glomus tumors that have a rich vascular network. Although a majority of the glomus tumors occur in the skin of the hand, they have also been reported in the deep soft tissue, bone, lungs, and gastrointestinal tract, especially the stomach. To our knowledge, only one such case has previously been reported primarily occurring in the liver. We report a case of a glomangioma primarily arising in the liver of a 57-year-old man who presented with right flank pain of several months' duration. A 3.0-cm hepatic mass was excised and consisted of numerous, small-to-medium branched vessels with the stroma containing small, round, regular cells with sharply outlined round-to-oval nuclei. Immunostains showed the tumor cells to be diffusely positive for vimentin and smooth muscle actin and to be focally positive for calponin. Collagen IV stained the pericellular matrix. The immunostain for CD34 highlighted the vascular network as well as outlined the tumor cells in many areas. Coexpression of actin and CD34 in glomus tumors, although unusual, has recently been reported in the literature. Despite its bland histology, the large tumor size and deep visceral location were suggestive of aggressive behavior; thus, a close clinical follow-up was recommended. The patient had an unremarkable postoperative course and has no evidence of metastatic disease 12 months after the procedure. An accurate diagnosis and an understanding the biology of this rare disease, especially in an unusual location, are crucial to its management.

Background: Kidney and renal pelvic cancer was the sixth most common cancer in men and 10th most common in women in the United States in 2018. Renal cell carcinoma (RCC), accounts for 86% of malignancies of the kidney. RCC patients are often asymptomatic; up to 25-30% have metastases at diagnosis. Few present with the triad of gross hematuria, flank pain, and abdominal mass. In RCC patients, 36% had 2 symptoms of the triad, and 60% had gross hematuria as 1 symptom. Point-of-care ultrasound (POCUS) offers a way to identify clinically meaningful anatomic abnormalities. This case series presents 3 patients in whom routine POCUS examination performed in an outpatient cardiology clinic found asymptomatic renal masses, resulting in surgical resection and cure of early-stage RCCs. Case Presentation: Patient 1: 54-year-old female with hypertension (HTN). Two solid masses were identified with POCUS in the right kidney. Patient 2: 63-year-old male with coronary artery disease (CAD) and HTN was seen at an 8-month follow-up visit. A 6-cm mass was identified in the left kidney. Patient 3: 69-year-old male with CAD, HTN, and smoking history seen at 5-month follow-up visit. A 3-cm mass in the right kidney was identified. Conclusions: Incorporating POCUS into the routine physical examination in the ambulatory care setting may improve rates of detection and increase the pretest probability of identifying renal pathology with formal imaging studies. With minimal clinician training, earlier and increased detection of asymptomatic RCC may result in improved patient survival.
