Does the length of time dried distillers' grain with solubles substitution for soybean meal affect physiological indicators and meat quality in finishing lambs?

This study examined how inclusion of dried distillers' grains with solubles (DDGS) in finishing lamb diets for different periods affects some physiological indicators and meat quality. A total of 40 male lambs were divided into four groups according to feeding regimen during the 120-day finishing period as follows: C120: no DDGS included in diet for 120 days; D120: DDGS included in diet for 120 days; D75: no DDGS included in diet for 45 days + DDGS included in diet for 75 days; D45: no DDGS included in diet for 75 days + DDGS included in diet for 45 days. Dietary inclusion rate of DDGS was 27.5%. Fattening performance and rumen parameters were not affected by treatment. Feeding regimens had no significant effect on meat quality except the instrumental tenderness and juiciness score. DDGS fed lambs had higher level of total trans fatty acids and n-6/n-3 ratio in meat. 10t-C18:1, 11t-C18:1 and 9c,11t conjugated linoleic acid contents of adipose tissue were higher in all the DDGS groups compared with C120 lambs (p < .001). These results suggest that soybean meal can be replaced with corn DDGS in lamb diets for up to 120 days during the finishing period with no adverse effects on some physiological response feedlot performance and meat quality.

Effect of dried corn distillers' grains with solubles and soybean meal supplements on physiological indicators and reproductive performance of ewes.

This study aimed to evaluate the effects of adding dried distillers' grains with solubles (DDGS) to the nutritional regimens of ewes at different time periods on reproductive traits, serum hormones and serum metabolites. In Experiment 1, 100 ewes were divided into 4 groups (n = 25) according to diet. The four diets were grass hay (H) alone (group H), H with barley (group H + B), H with DDGS for the whole feeding period (27 d) (group H + DDGS) or H and DDGS for 5 d (d 8-12 of oestrus cycle) (group H + DDGS5). Serum progesterone concentrations were affected by oestrus cycle (p < 0.001), but not by dietary treatments. However, feeding H + DDGS caused significant increases in serum insulin, leptin and growth hormone concentrations (p < 0.05). In Experiment 2, 30 ewes were divided into 2 groups (n = 15), receiving DDGS or soybean meal (SBM) during the prepartum period. Diets had no significant effect on weights of dams or lambs at birth; however, the weaning weights of lambs born from ewes of group DDGS were significantly higher (p < 0.05). Moreover, serum glucose, blood urea nitrogen, triglyceride and beta hydroxybutyric acid (BHBA) concentrations during the prepartum period were affected by dietary treatments and by time (p < 0.001). During the prepartum period, BHBA concentrations of ewes fed SBM were higher, while BHBA levels decreased during the last weeks of pregnancy regardless of diet. Lamb serum immunoglobulin G concentrations increased from 1 h to 24 h after birth (p < 0.001). Colostrum of ewes fed SBM had higher fat-free dry matter (DM) and protein contents in comparison to colostrum of ewes fed DDGS (p < 0.05). In conclusion, DDGS can be included as protein source in pregnancy rations up to 15% of DM to obtain reproductive performance outcomes equal to or exceeding those obtained with SBM.

Effects of pre-slaughter diet/management system and fasting period on physiological indicators and meat quality traits of lambs.

This study determined the effects of pre-slaughter diet/management system on blood and rumen parameters and meat-quality traits of Norduz lambs. Eighty lambs were divided into two groups according to diet (AH: alfalfa hay; BAH: alfalfa supplemented with 500 g/head barley) for 21 days. Following this period, lambs from each group were distributed among four groups according to pre-slaughter fasting period as 0, 12, 24 or 48 h. Cortisol concentrations were found to be significantly higher in the 24 h and 48 h groups when compared to the 0 h group (p<0.01). Diet and fasting period had limited effect on muscle glycogen content and ultimate pH·L*, WHC and moisture decreased in line with increases in the fasting period (p<0.01). In conclusion, carcass conformation and some meat quality traits were better in BAH lambs. Fasting had a negative effect on some meat quality parameters, with significant increases in some physiological stress indicators after fasting periods of 24 h or longer.

Transcriptomic and Immunohistochemical Profiling of SLC6A14 in Pancreatic Ductal Adenocarcinoma.

We used a target-centric strategy to identify transporter proteins upregulated in pancreatic ductal adenocarcinoma (PDAC) as potential targets for a functional imaging probe to complement existing anatomical imaging approaches. We performed transcriptomic profiling (microarray and RNASeq) on histologically confirmed primary PDAC tumors and normal pancreas tissue from 33 patients, including five patients whose tumors were not visible on computed tomography. Target expression was confirmed with immunohistochemistry on tissue microarrays from 94 PDAC patients. The best imaging target identified was SLC6A14 (a neutral and basic amino acid transporter). SLC6A14 was overexpressed at the transcriptional level in all patients and expressed at the protein level in 95% of PDAC tumors. Very little is known about the role of SLC6A14 in PDAC and our results demonstrate that this target merits further investigation as a candidate transporter for functional imaging of PDAC.

Shared gene expression alterations in prostate cancer and histologically benign prostate from patients with prostate cancer.

Prostate cancer (PCa) field effect alterations provide important clues regarding the initiation of these tumors and suggest targets for prevention or biomarkers for early detection. However, biomarkers of PCa field effects that have passed independent validation are lacking, largely because these alterations are subtle and difficult to distinguish from unrelated small changes in gene expression. We hypothesized that shared expression alterations in PCa and benign prostates containing PCa (BPCs) would have a higher potential for independent validation than alterations identified in BPCs alone. Expression analyses were performed on 37 PCas and 36 unmatched BPCs and were contrasted with 28 benign prostates (BPs) from patients free of PCa. Most of the protein-coding genes and nonexonic RNAs selected according to the hypothesis were validated by quantitative RT-PCR in an independent set of 51 BPCs and BPs. A statistical model based on two markers distinguished BPCs from BPs in the RT-PCR set and in an external microarray (area under the curve = 0.84 and 0.90, respectively). In addition, genes with predominant expression in stroma were identified by expression profiling of pure stroma and epithelial cells. Pathway analysis identified dysregulated platelet-derived growth factor receptor signaling in BPC stroma. These results validate our approach for finding PCa field effect alterations and demonstrate a PCa transcriptome fingerprint in nonneoplastic cells in prostates containing cancer.

Candidate serum biomarkers for prostate adenocarcinoma identified by mRNA differences in prostate tissue and verified with protein measurements in tissue and blood.

BACKGROUND: Improved tests are needed for detection and management of prostate cancer. We hypothesized that differential gene expression in prostate tissue could help identify candidate blood biomarkers for prostate cancer and that blood from men with advanced prostate disease could be used to verify the biomarkers presence in circulation. METHODS: We identified candidate markers using mRNA expression patterns from laser-capture microdissected prostate tissue and confirmed tissue expression using immunohistochemistry (IHC) for the subset of candidates having commercial antisera. We analyzed tissue extracts with tandem mass spectrometry (MS/MS) and measured blood concentrations using immunoassays and MS/MS of trypsin-digested, immunoextracted peptides. RESULTS: We selected 35 novel candidate prostate adenocarcinoma biomarkers. For all 13 markers having commercial antisera for IHC, tissue expression was confirmed; 6 showed statistical discrimination between nondiseased and malignant tissue, and only 5 were detected in tissue extracts by MS/MS. Sixteen of the 35 candidate markers were successfully assayed in blood. Four of 8 biomarkers measured by ELISA and 3 of 10 measured by targeted MS showed statistically significant increases in blood concentrations of advanced prostate cancer cases, compared with controls. CONCLUSIONS: Seven novel biomarkers identified by gene expression profiles in prostate tissue were shown to have statistically significant increased concentrations in blood from men with advanced prostate adenocarcinoma compared with controls: apolipoprotein C1, asporin, cartilage oligomeric matrix protein, chemokine (C-X-C motif) ligand 11 (CXCL11), CXCL9, coagulation factor V, and proprotein convertase subtilisin/kexin 6.

Anaplastic lymphoma kinase immunoreactivity correlates with ALK gene rearrangement and transcriptional up-regulation in non-small cell lung carcinomas.

Recently, the fusion gene EML4-ALK was identified in non-small cell lung carcinoma, which could be a potential therapeutic target. We investigated the prevalence of anaplastic lymphoma kinase protein expression in these tumors by immunohistochemistry and correlated the results with data from ALK molecular studies. Gene expression profiling was performed on 35 adenocarcinomas to identify cases with ALK gene up-regulation, which was correlated with protein overexpression by immunohistochemistry. Immunohistochemistry was also performed on an independent cohort consisting of 150 adenocarcinomas and 150 squamous cell carcinomas to evaluate the utility of anaplastic lymphoma kinase immunostaining as a screening tool. Florescence in situ hybridization for the ALK locus and reverse transcriptase-polymerase chain reaction for EML4-ALK were performed on tumors positive for anaplastic lymphoma kinase by immunohistochemistry. Transcriptional up-regulation of ALK was identified in 2 (6%) of 35 adenocarcinomas by gene expression profiling. These 2 cases were positive for anaplastic lymphoma kinase by immunohistochemistry, whereas the remaining 33 cases were completely negative. In the independent cohort, anaplastic lymphoma kinase immunostaining was positive in 1 of 150 squamous cell carcinomas and in 3 of 150 adenocarcinomas. The 6 cases positive for anaplastic lymphoma kinase by immunohistochemistry showed evidence of ALK locus rearrangement by florescence in situ hybridization but were negative for EGFR and KRAS mutation. The presence of EML4-ALK fusion transcript was confirmed in 2 cases by reverse transcriptase-polymerase chain reaction. In conclusion, anaplastic lymphoma kinase immunoreactivity in non-small cell lung carcinomas was associated with transcriptional up-regulation, ALK locus rearrangement, and the presence of EML4-ALK fusion transcript. Anaplastic lymphoma kinase immunohistochemistry may have utility as a screening tool or as a surrogate marker for the molecular techniques to detect the EML4-ALK fusion gene in these tumors.

Impact of sample acquisition and linear amplification on gene expression profiling of lung adenocarcinoma: laser capture micro-dissection cell-sampling versus bulk tissue-sampling.

BACKGROUND: The methods used for sample selection and processing can have a strong influence on the expression values obtained through microarray profiling. Laser capture microdissection (LCM) provides higher specificity in the selection of target cells compared to traditional bulk tissue selection methods, but at an increased processing cost. The benefit gained from the higher tissue specificity realized through LCM sampling is evaluated in this study through a comparison of microarray expression profiles obtained from same-samples using bulk and LCM processing. METHODS: Expression data from ten lung adenocarcinoma samples and six adjacent normal samples were acquired using LCM and bulk sampling methods. Expression values were evaluated for correlation between sample processing methods, as well as for bias introduced by the additional linear amplification required for LCM sample profiling. RESULTS: The direct comparison of expression values obtained from the bulk and LCM sampled datasets reveals a large number of probesets with significantly varied expression. Many of these variations were shown to be related to bias arising from the process of linear amplification, which is required for LCM sample preparation. A comparison of differentially expressed genes (cancer vs. normal) selected in the bulk and LCM datasets also showed substantial differences. There were more than twice as many down-regulated probesets identified in the LCM data than identified in the bulk data. Controlling for the previously identified amplification bias did not have a substantial impact on the differences identified in the differentially expressed probesets found in the bulk and LCM samples. CONCLUSION: LCM-coupled microarray expression profiling was shown to uniquely identify a large number of differentially expressed probesets not otherwise found using bulk tissue sampling. The information gain realized from the LCM sampling was limited to differential analysis, as the absolute expression values obtained for some probesets using this study's protocol were biased during the second round of amplification. Consequently, LCM may enable investigators to obtain additional information in microarray studies not easily found using bulk tissue samples, but it is of critical importance that potential amplification biases are controlled for.

Malignant peripheral nerve sheath tumors of cranial nerves and intracranial contents: a clinicopathologic study of 17 cases.

Malignant peripheral nerve sheath tumors (MPNSTs) arising from cranial nerves or their branches are very uncommon. The literature consists mainly of isolated case reports and small series. We identified 17 such cases in 14 males and 3 females. With one exception, the tumors affected adults (age range 5 to 69 y, mean 39, median 32). Sites of involvement included vestibular nerves (n=6), vagal nerves (n=4), facial nerves (n=3) (1 centered in the geniculate ganglion), and 2 unspecified cranial nerves in the posterior fossa. In addition, 1 tumor involved the optic chiasm (n=1). Only 1 tumor arose in brain parenchyma of (frontal lobe). All but 3 lesions were intracranial. Five tumors arose in patients who satisfied clinical criteria for neurofibromatosis type 1 (NF1). One patient with a vestibular tumor and presumed NF2 had previously undergone resection of a contralateral vestibular cellular schwannoma. One posterior fossa tumor was a malignant melanotic schwannoma. Four patients had postirradiation malignant peripheral nerve sheath tumors, 2 having been treated for optic chiasm glioma, both being NF1 affected. One patient was irradiated for hypothalamic pilocytic astrocytoma and another for cervical Hodgkin disease. Identifiable precursor lesions included schwannoma (n=4), plexiform neurofibroma (n=2), and solitary intraneural neurofibroma (n=2). All tumors were histologically high grade (6 grade III and 10 grade IV). Three tumors showed heterologous elements, 2 osseous, and 1 rhabdomyoblastic. More often scattered than diffuse, S-100 protein staining was noted in 11 of 16 tumors and variable collagen IV staining in 10 of the 16. Immunoreactivity for p53 protein was diffuse and strong in 7 of 11 tumors. Twelve patients died within 17 months to 3 years of diagnosis, 1 was lost to follow-up, 2 are very recent cases, and 2 patients are currently alive, 1 after 2 recurrences, and another with spinal leptomeningeal metastases. Malignant cranial nerve sheath tumors are rare and are associated with the same poor prognosis as those of spinal nerves at other sites.

Eruptive vellus hair cysts: report of a pediatric case with partial response to calcipotriene therapy.

Eruptive vellus hair cysts (EVHCs) are characterized by asymptomatic, follicular, comedonelike papules usually located on the anterior chest and abdomen. We present a pediatric case of EVHC associated with attention deficit hyperactivity disorder that partially responded to calcipotriene cream within 2 months. Our aim is to refamiliarize clinicians with a common albeit frequently unrecognized disorder of vellus hair follicles.

Malignant myoepithelioma of cranial dura.

Malignant tumors of myoepithelial origin have been increasingly recognized at a variety of sites. Herein, we describe an example of malignant myoepithelioma arising in intracranial dura. The patient is a 47-year-old woman who presented with intracranial hemorrhage and on magnetic resonance imaging was found to have an enhancing tumor. No extracranial primary tumor was identified. A gross total resection was performed. Histologically, it varied in pattern from diffuse to focally (<10%) ductular and consisted of epitheloid to spindle cells showing marked mitotic activity. Prominent infiltration of the dura was noted. Immunohistochemical stains showed convincing expression of cytokeratins (AE1/AE3 and CAM 5.2), S-100 protein, smooth muscle actin, and glial fibrillary acidic protein. Electron microscopy performed on formalin-fixed, paraffin-embedded tissue demonstrated cohesive cells with focal intermediate filament content and surface basal lamina formation at stromal interfaces. Occasional desmosomes with tonofilaments surrounded intercellular lumina containing masses of filamentous material. This example of malignant myoepithelioma is the first convincing primary salivary gland type tumor to arise in an intracranial location outside the sellar region or ear. Intracranial dura should be added to various sites at which this morphologically heterogenous tumor may arise.

Protective effects of trapidil in ischemia-reperfusion injury due to testicular torsion and detorsion: an experimental study.

OBJECTIVE: We aimed to detect the preventive effects of trapidil in ischemia-reperfusion (IR) injury due to testicular torsion and detorsion. METHODS: Forty prepubertal albino rats were used. In the IR group, torsion was created by rotating the left testis over 2 h, and detorsion was done by untwisting the testis. Bilateral orchiectomies were performed after 4 h. In study group, 2-h torsion was performed and trapidil was administered as a single dose 1 h before detorsion. Bilateral orchiectomies were performed after 4 h. In the sham group, a sham operation was done. In the sham plus trapidil group, a sham operation was done and trapidil was administered as a single dose. Testicular tissue malondialdehyde (MDA), nitric oxide (NO) and total sulfhydryl (T-SH) levels were determined for each group. The grades of interstitial injury were determined in histopathologic examination. RESULTS: The NO and MDA levels in the IR group were significantly higher than the study, sham and sham plus trapidil groups in the left testis (P<0.05, P<0.001 and P<0.001, respectively). A statistical difference was not found among study, sham and sham plus trapidil groups in the left testis in NO and MDA levels (P>0.05). The T-SH level in the study group was significantly higher than in the IR, sham and sham plus trapidil groups in left testis P<0.05). In the IR group (left testis), grade 1 interstitial injury was 30% (3/10), grade 2 injury was 60% (6/10) and grade 3 injury was 10% (1/10). In the study group (left testis), grade 1 interstitial injury was 30% (3/10) and there was no injury in 70% (7/10). CONCLUSION: Trapidil decreased free oxygen radical formation in testicular torsion and detorsion, and attenuated histopathological damage in the ipsilateral twisted testis.

Trapidil, an inhibitor for phosphodiesterase and platelet-derived-growth factor, ameliorates corrosive esophageal burn in rats.

Corrosive esophageal burn is a common health problem in the pediatric age group and causes serious esophageal injuries. The medical treatment in acute phase of corrosive esophageal injury is of particular importance for prevention of esophageal stricture. We therefore aimed to investigate the possible beneficial effect of trapidil (triazolopyrimidine), an inhibitor for phosphodiesterase and platelet-derived-growth-factor, during acute phase of esophageal corrosive injury. Wistar albino rats were randomly allocated to untreated, treated, and sham-operated groups (n = 10 for each group). Corrosive esophageal burn was generated with 10% NaOH solution. The rats were left untreated (untreated group) or treated with trapidil as a single dose of 40 mg/kg intraperitoneally after one hour of the injury (treated group). Abdominal esophageal segment was isolated and tied in sham-control group. The studied esophageal segment was removed from each animal after 24 hours. Malondialdehyde (MDA) and nitric oxide (NO) levels were measured in the esophageal tissues. The ulcer depth was graded by histopathologic examination. MDA and NO levels were significantly higher in the untreated group than in the treated group. Namely, trapidil treatment significantly decreased MDA and NO levels in the injured tissues, the levels of which are similar to those in the tissues of control animals. The grades of ulcer depth were significantly improved in the treated group. These results indicate that the reactive oxygen radicals increase in the early phase of corrosive esophagitis and cause tissue damage. We suggest that trapidil treatment may be useful in acute phase of corrosive esophageal injury.

Protective effects of trapidil in lung after abdominal aorta induced ischemia-reperfusion injury: an experimental study.

UNLABELLED: We aimed to investigate the protective effects of trapidil after the occlusion of abdominal aorta and the reperfusion injury in lung. Eighteen New Zealand albino rabbits were used in the study. In six animals [group 1, ischemia-reperfusion (IR) group], the abdominal aorta was exposed and a microvascular clamp was placed in the infrarenal abdominal aorta for 60 min. After the ischemic period, the microvascular clamp was removed and reperfusion was provided for 2 h. After the reperfusion period, the lungs were removed carefully and specimens were prepared for histopathological and biochemical studies in appropriate conditions. In group 2 (study group), trapidil (Rocarnal, Rentschler-UCB GmbH, Kerpen, Germany) was administered intraperitoneally as a single dose 1 h prior to trial, the IR procedure was performed and lung specimens were prepared similar to group 1. In group 3 (sham group), the infrarenal abdominal aorta was exposed and lung specimens were prepared for histopathological and biochemical studies at the end of the study. Histopathological changes, malondialdehyde (MDA), nitric oxide (NO) and total sulfhydryl group (T-SH) levels were evaluated. There was a statistical difference between the IR group and study group regarding NO and MDA levels (P < 0.05 and P < 0.01, respectively), but this was not detected between the IR group and the sham group (P > 0.05). There was no statistical difference among the three groups regarding T-SH levels (P > 0.05). While a statistical difference was found between the sham group and study group in the NO level (P < 0.05), no statistical difference was found in the MDA level (P > 0.05). There was a statistical difference in interstitial edema, PMN infiltration and hemorrhage scores among the groups (P < 0.05). There was a statistical difference between the IR group and study group in PMN infiltration (P < 0.05), but this was not detected between the groups in interstitial edema and hemorrhage scores (P > 0.05). There was a statistical difference between IR group and sham group in interstitial edema, PMN infiltration and hemorrhage scores (P < 0.05). Statistical difference was found between the sham group and study group in interstitial edema and hemorrhage scores (P < 0.05), but not in PMN infiltration (P > 0.05). CONCLUSIONS: Infrarenal abdominal aortic occlusion and reperfusion causes lung injury. We conclude that trapidil has preventive effects in the lung tissue after IR injury.

Bilateral upper eyelid edema in Melkersson-Rosenthal syndrome.

Melkersson-Rosenthal syndrome is an uncommon disorder characterized by a triad of facial nerve palsy, orofacial edema, and fissured tongue. A 42-year-old woman with Melkersson-Rosenthal syndrome presented with painless, nonpitting, bilateral asymmetric upper eyelid edema. The left eyelid was a bit larger than the right eyelid. CT and MRI demonstrated periorbital soft tissue thickening compatible with the microscopic findings of infiltration of lymphocytes, edema, and cystic dilatation of lymphatic vessels. After treatment by systemic doxycycline and corticosteroid, she showed some improvement of the eyelid edema. Isolated bilateral eyelids swelling may be observed in Melkersson-Rosenthal syndrome. In the case of unexplained nonpitting eyelid edema, biopsy should be performed.

Prognostic significance of mucin expression in gastric carcinoma.

In patients with gastric carcinomas, the role of the alteration of mucin expression in overall survival has been a matter of some speculation, but few studies have been reported. The aim of our study was to determine the relationship between MUC1, MUC2, and MUC5AC expression and patient survival, with a secondary aim designed to investigate the alteration of MUC expression within various clinicopathologic parameters. Forty-four specimens from gastric carcinoma patients were immunohistochemically evaluated using the monoclonal antibodies for MUC1 (EMA, clone E29), MUC2 (CCP58), and MUC5AC (human gastric mucin, clone 45M1). MUC1 expression increased in gastric carcinoma. MUC1 positivity was determined to be statistically significant, with poor clinicopathological parameters and decreased long-term survival. MUC5AC expression decreased in gastric carcinoma. In addition, patients with MUC5AC-positive tumors also had poor clinicopathological parameters and showed shorter survival than those with MUC5AC-negative tumors. MUC2 expression was not significantly associated with patient survival. We confirmed that the expression of mucins is associated with characteristics of differentiation in gastric carcinoma. Poor patient outcomes were seen in gastric carcinomas with MUC1 mucin expression and MUC5AC positivity.

A confirmatory report for the close interaction of Helicobacter pylori with gastric epithelial MUC5AC expression.

BACKGROUND: Helicobacter pylori (H. pylori) infection is associated with the development of gastritis and peptic ulcer and is presumed to be a risk factor for low-grade B-cell lymphoma and gastric cancer. H. pylori also causes critical alterations in gastric mucin structure. Our aim was to determine the effect of H. pylori on MUC1, MUC2, and MUC5AC expression. METHODS: Thirty H. pylori-positive and 15 H. pylori-negative antral gastric endoscopic biopsy specimens were evaluated for MUC1, MUC2, and MUC5AC expression with immunohistochemical staining. From the same specimens, we scrutinized the presence of H. pylori infection by hematoxylin and eosin and immunohistochemical staining. RESULTS: In H. pylori infected patients, the expression of MUC5AC was found to be localized to the cells in the superficial epithelium and upper parts of the gastric glands. The number of MUC5AC-expressing cells and the staining intensity of MUC5AC were shown to decrease in patients with H. pylori infection. Histopathology and immunostaining patterns of gastric mucins implied that H. pylori was physically associated with extracellular MUC5AC and MUC5AC-producing cells. H. pylori infection does not significantly affect staining intensity and patterns of MUC1 and MUC2 expressions. MUC1 was not found in dysplastic tissues or intestinal metaplasia areas. MUC5AC was expressed in dysplastic areas, but not in intestinal metaplasia. MUC2 was expressed in both dysplastic and intestinal metaplasia areas. CONCLUSION: H. pylori decreases the amount of MUC5AC expression. With reducing MUC5AC-producing cells and MUC5AC mucin, H. pylori may potentially cause significant alterations of the structure and function of gastric mucins. H. pylori-dependent inhibition of mucin synthesis deserves more investigations to clarify the role of H. pylori and gastric MUC5AC interaction.

Chondroid syringoma of the upper lip: a case report.

Chondroid syringoma (mixed tumor of the skin) is a rare benign neoplasm of the sweat glands which often occurs in the head and neck region. We present a 73-year-old white farmer man with a mass in the anterior surface of the upper lip that was histologically diagnosed as a chondroid syringoma after surgical wide excision. There were no signs of recurrence during a follow-up of 14 months.
