The value of MSCT in diagnosis of parotid benign tumor (An analysis of 84 cases)

Objective:The purpose of the study was to assess diagnostic performance of MSCT images in patients with parotid benign tumors and provide useful criteria for the characterization of their various pathological types preoperatively. Methods: Retrospectively analyzed clinical and imaging characteristics of 84 cases of pathologically confirmed primary parotid benign tumors. MSCT plain-scan and enhanced-scan were performed in all cases. After injection of 50 mL contrast material at a rate of 3.5 mL/s,spiral CT scans were obtained at arterial and venous phases with scanning delay of 30 s and 75 s,respectively. The attenuation change and enhancement patterns in the tumors were assessed. Quantitatively assess the increased CT number of the tumors in different enhanced-phases compared with the plain-scan and the ratio of increased CT number at venous phase scanning to that at arterial phase scanning also was calculated. Results:In all of 84 cases,40 cases were solitary pleomorphic adenomas,29 cases were adenolyphomas,6 cases were multiple tumors,2 cases were bilateral,15 cases were Basal cell tumor,and one of them had two small lesions. The diameter was 1–5 cm in most of cases,whose margin was smooth and clear,cystic changes in some cases. At two-phase scans,pleomorphic adenomas showed a pattern of slight enhancement and venous enhancement,adenolymphomas showed a pattern of strong enhancement at arterial phase scanning with a decrease at venous phase scanning,basal cell tumor showed a pattern of persistent strong enhancement with commonly significant cystic areas. The ratio of increased CT number was significant different between adenolymphomas and other pathological types. Conclusion: The evaluation of enhancement patterns at two-phase enhanced-scan MSCT is helpful in the differential diagnosis of parotid gland benign tumors.

Conclusions: Benign breast tumor can be excised through cosmetology incision, and no obvious scar leaves behind, so it can satisfy the cosmetic requirement of many patients.

Pleomorphic adenoma(mixed tumor)of the upper lip:A case report

BACKGROUND Salivary gland tumors are relatively rare.Most minor salivary gland tumors are malignant with benign tumors accounting for 18%of the tumors.Pleomorphic adenoma(PA)is the most common salivary gland tumor.Lip PA is uncommon with 9.8%occurring in the upper lip.We are adding on the knowledge of the rare upper lip PA(benign mixed tumor).CASE SUMMARY We report an upper lip PA(benign mixed tumor)in a 28-year-old man.His complaint was a painless swelling on the upper lip.A painless,non-tender,well-circumscribed,slightly mobile,sessile,nodular,and rubbery(in consistency)tumor measuring 5.0 cm x 2.0 cm was noted on the left side of his upper lip.The overlying skin was not fixed and of normal color.There was no ulceration,and palpation did not elicit pain or bleeding.There was no history of trauma.Blunt dissection was used to completely excise the nodular,whitish,and encapsulated tumor.Microscopy showed a well-circumscribed and partly encapsulated biphasic lesion,with large lobules of myxo-chondroid stroma and intervening cellular nodules of basaloid cells,well-formed tubules containing eosinic secretion,and nests of myoepithelial cells.A diagnosis of PA(benign mixed tumor)was confirmed.CONCLUSION Blunt dissection is indicated to preserve the cosmesis and function of the upper lip.

Duodenum-preserving resection and Roux-en-Y pancreatic jejunostomy in benign pancreatic head tumors

This study was conducted to explore the feasibility of partial pancreatic head resection and Roux-en-Y pancreatic jejunostomy for the treatment of benign tumors of the pancreatic head(BTPH). From November 2006 to February 2009, four patients(three female and one male) with a mean age of 34.3 years(range: 21-48 years) underwent partial pancreatic head resection and Roux-en-Y pancreatic jejunostomy for the treatment of BTPH(diameters of 3.2-4.5 cm) using small incisions(5.1-7.2 cm). Preoperative symptoms include one case of repeated upper abdominal pain, one case of drowsiness and two cases with no obvious preoperative symptoms. All four surgeries were successfully performed. The mean operative time was 196.8 min(range 165-226 min), and average blood loss was 138.0 m L(range: 82-210 m L). The mean postoperative hospital stay was 7.5 d(range: 7-8 d). In one case, the main pancreatic duct was injured. Pathological examination confirmed that one patient suffered from mucinous cystadenoma, one exhibited insulinoma, and two patients had solid-pseudopapillary neoplasms. There were no deaths or complications observed during the perioperative period. All patients had no signs of recurrence of the BTPH within a follow-up period of 48-76 mo and had good quality of life without diabetes. Partial pancreatic head resection with Roux-en-Y pancreatic jejunostomy is feasible in selected patients with BTPH.

Liver transplantation for benign liver tumors

Benign liver tumors are common lesions that are usually asymptomatic and are often found incidentally due to recent advances in imaging techniques and their widespread use.Although most of these tumors can be managed conservatively or treated by surgical resection,liver transplantation(LT)is the only treatment option in selected patients.LT is usually indicated in patients that present with life-threatening complications,when the lesions are diffuse in the hepatic parenchyma or when malignant transformation cannot be ruled out.However,due to the significant postoperative morbidity of the procedure,scarcity of available donor liver grafts,and the benign course of the disease,the indications for LT are still not standardized.Hepatic adenoma and adenomatosis,hepatic hemangioma,and hepatic epithelioid hemangioendothelioma are among the most common benign liver tumors treated by LT.This article reviews the role of LT in patients with benign liver tumors.The indications for LT and long-term outcomes of LT are presented.

Rarity among benign gastric tumors: Plexiform fibromyxoma-Report of two cases

Plexiform fibromyxoma is a very rare mesenchymal tumor of the stomach, found almost exclusively in the antrum/pylorus region. The most common presenting symptoms are anemia, hematemesis, nausea and unintentional weight loss, without sex or age predilection. We describe here two cases of plexiform fibromyxoma, involving a 16-year-old female and a 34-year-old male. Both patients underwent complete resection(R0) by distal gastrectomy and retrocolic gastrojejunostomy(according to Billroth 2); for both, the postoperative course was uneventful. Histology showed multiple intramural and subserosal nodules with characteristic plexiform growth, featuring bland spindle cells situated in an abundant myxoid stroma with low mitotic activity. Immunohistochemistry showed α-smooth muscle actin-positive spindle cells, focal positivity for CD10, and negative staining for KIT, DOG1, CD34, S100, β-catenin, STAT-6 and anaplastic lymphoma kinase. One of the cases showed focal positivity for h-caldesmon and desmin. Upon followup, no sign of disease was found. In the differential diagnosis of plexiform fibromyxoma, it is important to exclude the more common gastrointestinal stromal tumors as they have greater potential for aggressivebehavior. Other lesions, like neuronal and vascular tumors, inflammatory fibroid polyps, abdominal desmoid-type fibromatosis, solitary fibrous tumors and smooth muscle tumors, must also be excluded.

Detecting benign uterine tumors by autofuorescence lifetime imaging microscopy through adjacent healthy cervical tissues

The endogenous fluorophores such as reduced nicotinarmide adenine dinucleotide(phosphate)(NAD(P)H)and favin adenine dinucleotide(FAD)in cells and tissues can be imaged by fuo-rescence lifetime imaging microscopy(FLIM)to show the tisute morphology features,as well as the biomolecular changes in microenvironment.The two important coenzymes in cellular metabolism,NAD(P)H and FAD,can be used to monitor the cellular metabolic status.This work proposed a novel method to study the uterine metabolism at the adjacent site of healthy cervix.It was found that the benign uterine tumors such as leiomyomas and adenomyosis with abnormal cell growth can be detected by measuring the fluorescence lifetime of NAD(P)H and FAD in adjacent healthy cervical tisues.This method opened a novel strategy for alicted women to undergo the cervical biopsies instead of hysterectomies for detecting tumors,which can preserve the fertility of patients.The FLIM studying on NAD(P)H and FAD indicated the correlation between metabolism and some diseases,including diabetes,hyperthyroidism and obesity.It was also suggested that the metabolic level might be quite different for a patient with a malignant tumnor history.

Frequency of Benign and Malignant Tumors in Localized Vitiligo in Comparison to Generalized and Universal Vitiligo

Background: Autoimmune diseases like pemphigus and systemic lupus erythematosus are protective against skin malignancies like basal cell carcinoma and squamous cell carcinoma. Objective: As vitiligo is an autoimmune diseases, the aim of the present work is to record the frequency of all benign and malignant skin tumors among patients with different severity of vitiligo and to be compared with the skin tumors in healthy control. Patients and Methods: This is a case series, descriptive study done in the Department of Dermatology—Baghdad Teaching Hospital, Baghdad, Iraq, during the period from May 2014-May 2015. History was taken from each patient with vitiligo regarding age, gender, duration, personal and family history of vitiligo and other autoimmune diseases such as diabetes mellitus, thyroid dysfunction, and alopecia areata. Patients were assessed for past and present history of photodermatosis and any skin cancers. Healthy control was considered. Results: Three hundred and fifty patients with vitiligo were included in this study: 50 patients with universal vitiligo, 100 patients with generalized vitiligo, and 200 patients with localized vitiligo as well as 500 subjects as a healthy control. The ages of all studied subjects ranged between 31 and 77 years. Twenty four(48%) patients with universal vitiligo were males and 26 (52%) were females;49(49%) patients with generalized vitiligo were males and 51(51%) were females;101(50.5%) patients with localized vitiligo were males and 99(49.5%) were females and 235(47%) of control were males and 265(53%) were females. All skin tumors were seen to be high in healthy subjects and lower or absent in patients with vitiligo. Also patients with mild vitiligo had a higher frequency of skin tumors including benign and malignant than patients with severe vitiligo especially in patients with universal vitiligo. In addition, no photosensitivity or actinic reticuloid was detected in patients with vitiligo. Conclusions: Vitiligo especially generalized and universal type as an autoimmune disease had a protective action against photodamage, photosensitivity and skin tumors whether benign or malignant.

Nasal Dermoid Cyst with Sinus Tract Intranasal Bone: A Case Report

Dermoid cysts are benign tumors originating from germ cells, which can form in various locations, including the nasal area in rare cases. They are of unknown exact etiology, but it is suggested that it is due to abnormal tissue migration during early embryonic development. Nasal dermoid cysts albeit rare, can present in various forms such as sinuses, fistulas, or intracranially extending tracts. They can be asymptomatic and incidentally discovered or present with a visible external mass or sinus that is either painful, infected or cosmetically concerning. If nasal dermoid cysts with an intra-nasal bone sinus tract are left untreated, they can lead to life-threatening complications. This report describes the case of a 6-year-old girl with a nasal dermoid cyst connected to a superficial punctum by an intra-nasal tract. She had undergone surgical excision of a nasal swelling previously diagnosed as a dermoid cyst. One year later, she returned to our clinic with a recurrence of the nasal swelling. Imaging tests revealed a nasal dermoid cyst with a tract extending to the nasal tip, without intracranial expansion. The cyst, along with the entire tract, was successfully removed surgically, and the postoperative follow-up indicated no complications. Histopathology confirmed the diagnosis of a dermoid cyst. This case underscores the significance of considering the dermoid tract in nasal cyst cases and the necessity of its complete removal to prevent recurrence.
