Background: Lipomas are benign fatty tumors made of fat tissue. Bladder lipomas are extremely rare. For this reason, it is necessary to be aware of the imaging features when incidentally detected in imaging. Case Report: In the abdominal computed tomography (CT) performed as part of the follow-up examination of a 43-year-old patient, who had undergone surgery for adrenal adenoma five years earlier, a 14x9x8 mm smoothly marginated, ovoid-shaped, hypodense mass lesion with a homogeneous internal structure was detected in the anterior bladder wall. The pre-contrast density of the lesion was measured as -105 HU. The magnetic resonance imaging performed one year after the CT examination revealed a 14x9x8 intramural mass in the bladder wall, showing protrusion toward the lumen. The group was observed to be markedly hypointense on fat-suppressed T1 and T2-weighted images and considered consistent with a bladder lipoma. Discussion: Bladder lipomas are benign lesions that can vary in clinical presentations but usually cause hematuria. The differential diagnosis of bladder lipomas includes other mesenchymal rare benign tumors that can arise from the urinary bladder submucosal layer, including leiomyoma, hemangioma, plasmacytoma, fibroma, and neurofibroma, in imaging bladder lipomas present as homogeneous lesions containing macroscopic fat. Only the liposarcoma and pelvic lipomatosis could also show similar features. The less differentiated liposarcomas tend to present more heterogeneous enhancement, irregular-shaped margins, and infiltrative behavior. Also, appropriate multiplanar reconstructions may allow the radiologist to determine it is an extravesical pelvic lipomatosis. Conclusion: Using CT and MRI, these lesions rich in adipose tissue can be distinguished from other lesions, and their diagnosis can be made to a great extent. However, a histopathological examination is required for a definitive diagnosis.

Carcinoid tumors are quite common neoplasm of the appendix. The clinical presentation of these lesions somewhat corelates to that of acute appendicitis, or the tumors are asymptomatic. The carcinoids are commonly found incidentally during histopathological examination of the resected appendix following appendectomy or other abdominal procedures. Appendiceal carcinoids usually behave as benign tumors and appendicectomy alone is a sufficient treatment in the majority of cases, while for larger lesions (lesions at the base of the appendix), right colectomy should be performed. The prognosis of patients with local appendiceal carcinoids is excellent. The present study reports the case of a 49-years-old male patient that presented with recurrent abdominal pain of 6 weeks duration. The patient underwent successful appendectomy and recovered four days later. Subsequently, an appendiceal carcinoid tumor located at the tip of the appendix was diagnosed by histopathological examination. Follow-up examination one year after surgery revealed that the patient was well with no discomfort.

Objective: To reassess the double continence technique for open retropubic radical prostatectomy, proposed by Malizia and employed by Pagano et al., with the “tension free continuum-urethral anastomosis” (T.F.C.U.A.) personal modification and the use of image magnification optical systems and appropriate and delicate surgical tools. Materials and methods: A total of 173 radical retropubic prostatectomies, performed by the same surgeon, were evaluated in terms of early and late continence. Results: The presence of residual prostate cancer cells within the muscle layer was always excluded by the histopathological examination that also demonstrated that the muscle layer was well represented; satisfactory outcomes were obtained in terms of both early urinary continence (60%) and urinary continence at 6-12 month follow-up (92.4% for the whole series and 97.2% for the last series of patients). Conclusions: The “tension free” anastomosis obtained by the suspension of the anterior bladder wall to the the pubis along the median line allowed to achieve satisfactory outcomes in terms of urinary continence, even if these data obviously need to be confirmed by other series and comparative trials.

Abstract Background: Parotid neoplasm is a result of inadequate surgical incision during the treatment of head and neck cancers, and most of them are benign tumors. Hence, to explore a new surgical incision for parotid benign tumor in order to minimize the scar size on the premise of guaranteeing the safety of operation.Methods: We conducted a retrospective study of 48 patients who had undergone parotid surgeries from Jan. 01 2008 to Dec. 30 2014 at the department of otolaryngology, Jinshan Hospital of Fudan University. Histopathological examination confirmed benign parotid tumor (Warthin's tumor, pleomorphic adenoma, cysts, and monomorphic adenomas.) in all cases. All patients underwent a mini incision (cutting the skin directly on the surface of the tumor, and the incision was slightly longer than the diameter of the tumor). Results: Among the 48 cases, no recurrence and facial nerve injury were reported during the follow-up period of more than 4 years. Two cases of saliva fistula and one case of temporary facial nerve dysfunction were reported; however, they recovered quickly after symptomatic treatment.Conclusion: Extracapsular dissection is a safe and effective surgical procedure for the treatment of parotid benign tumor, and the postoperative scar is very small.

Background: Cardiac fibromas are rare benign tumors of the heart composed of fibroblasts and collagen. They are common among children and adolescents but are rarely present in adults. Case presentation: We here report the case of a fifty-seven-year-old man who complaining of a 2-year history of chest tightness at rest. Transthoracic echocardiography detected a severe calcified mass protruding outside the right ventricular anterior wall near the apex. The patient was referred for tumor resection. The calcified mass was determined to be a cardiac fibroma with postoperative histopathological examination. The patient experienced an unremarkable post-operative recovery and was discharged 8 days later. Subsequent follow-up has shown complete freedom from his troublesome symptom. Conclusions: Preoperative diagnosis with various imaging modalities and early surgery are the keys to improve prognosis of patients with cardiac fibromas.

Pilonidal sinus in the intermammary region is a rare location of an inflammatory condition commonly occurring in the natal cleft. It is typically characterised by a pus and hair containing cavity in the skin lined by granulation tissue connecting the skin surface. A 22 year-old female presented with chronically discharging sinuses in the intermammary region with recurrent abscess formation for one year duration. Although a rare location, clinical diagnosis of pilonidal sinus was made. Complete excision of sinus tract with abscess cavity with primary closure was performed under general anaesthesia. Histopathological examination confirmed pilonidal sinus. On follow up, the scar was healthy with no keloid formation. Pilonidal sinus may rarely occur in intermammary region. Complete excision and primary closure is the mainstay treatment.

Bladder Leiomyoma

Bladder leiomyomas (BLs) are extremely rare benign tumors of mesenchymal origin. The exact pathophysiological mechanisms that lead to their appearance remain unclear including hormonal disorders, chromosomal abnormalities, and fetal remnants in the bladder. They usually remain asymptomatic for a long period of time. Solitary fibrous tumors (SFTs) are also rare neoplasms of mesenchymal origin with malignant potential usually affecting the pleura. The pathogenesis of SFTs remains unclear. We report the case of a 28-year-old male presenting with SFT of the pleura and synchronous BL. The patient presented with persistent cough as a sole symptom. Computed tomography (CT) of the thorax revealed a pleural mass, which was surgically removed and proved to be a SFT. At an early follow-up, abdominal CT scan revealed a bladder wall mass that proved to be a BL. This is the first report of BL with synchronous SFT of the pleura. Synchronous BLs and SFTs may be incidental, but the coexistence of two mesenchymal tumors at different sites, in a young patient, may raise the suspicion of a new clinical syndrome that warrants further investigation.

Renal leiomyoma is a rare benign mesenchymal tumor of the kidney that predominantly originates from the renal capsule or pelvis. However, because of its nonspecific clinical and imaging features, renal leiomyoma remains poorly characterized and may even lead to radical or partial nephrectomy on the basis of preoperative suspicion of renal carcinoma. We herein present a case involving a 12-year-old boy with acute abdominal pain who was diagnosed with renal leiomyoma based on both clinical imaging and histopathological examination. One year after radical nephrectomy, the patient recovered to good condition. This case demonstrates that the comprehensive application of imaging and histology are essential for early clinical diagnosis and effective treatment of renal leiomyoma.

The desmoplastic fibroblastoma (DF) is a rare benign soft-tissue tumor of fibroblastic and myofibroblastic origin, and its occurrence in the oral cavity is rare. This study details a new case of an elevated lesion in the alveolar ridge of a 59-year-old woman, painful during mastication. The histopathological exam showed non-encapsulated stellate-to-spindle cells proliferation in a hypocellular collagen-rich stroma. Tumor cells were strongly and diffusely positive for vimentin, and some cells were focally positive for α-smooth muscle actin, CD99, and β-catenin. The exams were conclusive for DF diagnosis. The patient is in the follow-up period, and no recurrent lesions were detected within one year. Despite having similar clinical, pathological, and immunohistochemical features to the cases previously described, the DF in this report is at an unusual oral site and associated with painful symptomatology. Immunohistochemistry is an important tool in DF cases where the histopathological examination is not conclusive.

Intestinal Gvhd

Abstract Intestinal TMA, a upcoming and serious problem after HSCT, usually manifests diarrhea, vomiting, GI bleeding and abdominal pain as initial clinical presentations similar to those of intestinal GVHD. But intestinal TMA should be distinguished from GVHD, because they needed to be treated in absolutely different way. Here we investigated the incidence of intestinal TMA and evaluated their clinical progressions in HSCT patients. We retrospectively reviewed 243 gastrointestinal mucosal biopsy slides obtained from HSCT patients having suffered from GI problems in the Catholic University Hospital, from 2000 to 2004. The collected cases were reviewed by two pathologists blindly and classified into TMA; showing microthrombi formation in the lumina of microvasculatures, GVHD; showing epithelial apoptosis and/or loss of glands, TMA+GVHD and non-specific inflammation. And next, their incidence and clinical outcomes were analyzed. On histopathological examination, 15 out of 243 cases (6.2%) showed luminal thrombi of microvasculature compatible with TMA, 58 cases (23.9%) showed findings compatible with GVHD, 3 cases (1.2%) showed both TMA and GVHD, and 173 cases (71.2%) showed nonspecific gastroenteritis. On peripheral blood smear examination, all 15 TMA cases showed less than 1% of fragmented RBC at the time of biopsy. But 2 out of 15 cases (13.3%) showed increase to 8% and 10% of fragmented RBC in follow-up, and they had been aggravated clinically and improved only after treatments including discontinuing immunosuppressant and plasma exchange. Among 58 GVHDs, 34 patients (75.9%) were improved with steroid pulse therapy, but 14 patients (24.1%) failed. These results show that intestinal TMA is not infrequent in HSCT patients and can be combined with intestinal GVHD. In conclusion, intestinal TMA should be recognized in pathological diagnosis of HSCT patients. It is important to differentiate intestinal TMA from GVHD in patients suffering from severe and refractory diarrhea after HSCT.

The imaging features of 42 histopathologically confirmed cases of Gastrointestinal Stromal Tumors (GIST) were analyzed, to observe the pattern of metastasis. At presentation 22 of 42 patients (52.3%) showed metastasis. During follow-up, three more cases developed metastasis, within one year of resection. Mesentery, omentum, and liver were the most frequent sites for metastasis. Other sites that were rarely reported to be involved were increasingly recognized to show metastasis due to longer survival. The metastasis often showed attenuation and enhancement characteristics, similar to primary GIST, and frequently showed necrosis, hemorrhage, and calcification.
