INTRODUCTION: It is a challenge to make accurate pre-surgical diagnosis for renal tumors. This study is to report the findings, management, and outcome of one rare case of ossification in a cystic renal mass. We present and discuss the pathological characteristics, radiologic features, and treatment alternatives of the patient. PATIENTS AND METHODS: A 38 years old female patient had intermittent epigastric pain and microscopic hematuria for two months. Computerized tomography (CT) scan and Magnetic Resonance imaging (MRI) showed a mass with rough edge and dense calcification in the upper pole of the right kidney and normal left kidney. Pre-operative diagnosis is cystic nephroma or cystic renal mass (Bosniak III type, Bosniak renal cyst classification). GFR was within normal limits for age and no other significant laboratory aberrations were noted. Patient underwent a right retroperitoneal laparoscopic partial nephrectomy (margin status was negative). A mini literature review was performed to highlight the principals of diagnosis and treatment of cystic renal mass with heterotopic ossification. RESULTS: The entire renal mass was successfully removed from upper pole of the right kidney by laparoscopic nephron sparing surgery. The size of renal mass is 38×35×30 mm3 with thick and hard capsular wall. The cystic cavity contains yellow lipid-like substances without stone. Histological examination revealed renal cyst in which the cyst wall reveals fibrosis and no obvious lining epithelium. The additional unique feature includes the presence of dense calcification and ossification in the renal mass. Localization tissue of yellow bone marrow was detected. No complications occurred in 9 months after surgery during follow-up. CONCLUSIONS: Cystic renal mass with heterotopic ossification is a rare case of non-malignant renal tumor. Whether surgery is needed depends to whether patients have symptoms. For symptom renal tumors, laparoscopic nephron sparing surgical procedure is recommended. Furthermore, complete surgical resection of the lesion is needed when the mass is suspected to be malignant. An accurate histologic diagnosis is key in its diagnosis.

Multilocular cystic nephroma is a relatively rare benign tumour of the kidney, which usually presents as a unilateral multicystic renal mass without solid elements. The lesions typically have a bimodal age, with peak incidence in male children under 24 months and another one in women over 40 old. We present an unusual case report of multilocular cystic nephroma in the right kidney in a 30-year-old male. Laparoscopic partial nephrectomy was performed. The pathologic examination confirmed a multilocular cystic nephroma in the right renal specimens. We present the image findings, pathological features, treatment alternatives and a review of the literature.

The hemangiopericytoma (HPC) of the kidney is extremely rare perivascular neoplasm. There are no specific radiological or clinical findings that can aid in preoperative diagnosis. In the world literature, only 41 cases of renal HPC have been previously documented. We report on a 56-year old woman with renal HPC of the right kidney who had lung metastasis at the time of diagnosis. The right radical nephrectomy was performed and the combination chemotherapy was given, postoperatively. After 3 cycles of chemotherapy, disease was stable, but progression was seen at the end of 6 courses of chemotherapy. The patient died due to progression of disease ten months later after the diagnosis. We suggested that for patients present with renal mass, renal HPC as well as the other renal tumors should be considered in the differential diagnosis.


We report a very rare case of squamous cell cancer of the right foot which had metastasize to the ipsilateral popliteal lymph node after initial diagnosis and treatment for the loco-regional disease.

Abstract We present an interesting case of a 70-year-old female who presented with haematuria on the suspected cancer pathway. Renal ultrasound showed a vascular renal mass on her right kidney measuring 8x7cm with an unremarkable left kidney. She underwent a laparoscopic radical nephrectomy following confirmation of an 8cm renal mass in the right kidney on the contrasted staging CT scan with a repeat review at the multidisciplinary meeting. Post-operatively a subsequent review of the pre-operative CT and ultrasound scan, showed an incidental large left(contralateral) upper quadrant retroperitoneal fatty mass sized 15x10cm, displacing the stomach and spleen. Further investigation in the form of an MRI Abdomen excluded features of a liposarcoma, resulting in the diagnosis of a large retroperitoneal lipoma. This case highlights the significance of selective attention in imaging interpretation. We believe this to be a prime example of the level of meticulousness required as fat-rich tissues have low attenuation on CT-scans, which can be easily missed out. A cautious multi-clinician interpretation of scans should be performed to avoid missing potentially sinister pathology which would impact patient care dramatically. This case has led to more thorough review of future pre-operative imaging by the operating surgical team.

Introduction. Hydatid disease is a cyclozoonotic parasitic infestation caused by the cestodeEchinococcus granulosus. The cysts mainly arise in the liver (50 to 70%) or lung (20 to 30%), but any other organ can be involved, in abdominal and pelvic locations, as well as in other less common sites, which may make both diagnosis and treatment more complex. Isolated renal involvement is extremely rare.Case Presentation. We report a rare case of isolated renal hydatid disease in a 71-year-old man with a history of vague abdominal pain, anemia, fever, and microhematuria. Ultrasonographic examination revealed a complex cyst in the right kidney, including multiple smaller cysts with internal echoes. A magnetic resonance scan of the abdomen confirmed the findings, and hydatid cyst disease was diagnosed. Right nephrectomy was performed, and microscopic examination confirmed the diagnosis of hydatid cyst. Albendazole, 10 mg/kg per day, was given for 4 weeks (2 weeks preoperatively and 2 weeks postoperatively).Conclusion. Isolated primary hydatidosis of the kidney should always be considered in the differential diagnosis of any cystic renal mass, even in the absence of accompanying involvement of liver or other visceral organs.

Paragangliomas can be found from the skull base to the sacrum. Sinonasal paragangliomas are infrequent. A 16-year-old female reported spontaneous discrete bilateral epistaxis once a month beginning when she was 3 years of age. Computed tomography showed an expansive hypervascular mass occupying the right nasal cavity and nasopharynx. Sinonasal paragangliomas usually occur in middle-aged women. Radiologic investigation is essential for the diagnosis of sinonasal paragangliomas and evaluating extension of the lesion. Endoscopic and conventional approaches are effective, and preoperative embolization is paramount for reducing bleeding risk. Histopathological features cannot differentiate benign from malignant paragangliomas, and since metastasis may eventually occur, follow-up must be carried out for a long period of time.

Acute clavicle osteomyelitis in children is rare representing <3% of osteomyelitis cases. We treated a 12-year-old boy who presented with acute pain in the right clavicle and high fever for 4 days. MRI showed abnormal signal in the right clavicle with periosteal reaction.Staphylococcus aureusisolated from blood was susceptible to methicillin, clindamycin, and macrolides. Clindamycin was given intravenously for 3 wks and orally for another 3 wks with no recurrence. We reviewed clavicle osteomyelitis cases in children searching PubMed English literature. From a total of 89 studies retrieved, only 6 fulfilled the criteria and were analyzed. Sixteen patients (56% female) were included with a median age of 9 yrs (range 2 wks–16 yrs). Osteomyelitis was hematogenous in most cases, withS. aureusbeing the most frequent cause, isolated from either blood or tissue. Symptoms included fever, swelling, and localized bone tenderness. Antimicrobial therapy lasted for 4–12 weeks (median 7.5). Three patients required drainage or curettage. Recurrence occurred in 1/16 cases (6.2%) and persistence of symptoms occurred to 2/16 cases (12.5%) reported before 90s with unknown antimicrobial susceptibility of the pathogen. Acute clavicle osteomyelitis mainly affects older children and has generally good prognosis.Staphylococcus aureusis most commonly implicated and surgery may be needed.

Background: Often, the cause of bony torticollis is difficult to determine, especially in cases of multiple craniovertebral junction anomalies. Case Description: We report a rare case of a dysplastic C1 vertebra (assimilation to the right occiput and C2, a nonseparated left odontoid, and discontinuity in both anterior and posterior arches of the atlas) in a 6-year-old child with progressive torticollis. Notably, the mechanism of torticollis was not a rotatory subluxation of C1-C2, but differential growth between C1-C2. The child underwent a successful C1-C2 Goel and Harms fusion with reduction/correction of the torticollis. Conclusion: Torticollis caused by differential growth between the C1 and C2 vertebrae resulting in a nonrotatory subluxation/torticollis in a 6-year-old child, was successfully managed with a C1-C2 Goel and Harm’s fusion.

Abstract Background Glomus tumor (GT), which are neoplasms of the glomus body, usually occur in the extremities, particularly under the nail bed. GT occurring in the bladder is very rare and has been reported as sporadic. In the present study, a rare case of bladder GT is reported and its clinical and histopathological characteristics are summarized by literature review. Case presentation A 57-year-old woman presented with intermittent gross hematuria for 2 years. Urinalysis displayed hematuria. The bladder ultrasound showed an avascular and homogeneous isoechoic polypoid mass with a maximum diameter of 6 mm at the right lateral wall of bladder. The bladder endoscopic examination showed a polypoid lesion, with a smooth surface, located in the right lateral wall. Then, a transurethral resection was performed, its histopathological features indicated a benign GT. Conclusions GT arising in the bladder is extremely rare, and only four cases have been identified in studies reported in English. It is difficult to diagnose bladder GTs according to their clinical features. The gold standard method used for their diagnosis is histopathology. However, it should also be considered in the differential diagnosis for bladder mass.
