Abstract Objectives LCH is a rare systemic disorder characterized by an infiltration of CD1a+/Langerin+ histiocytes. LCH commonly involves bone, skin, and lymph nodes in children. Hepatic involvement is rarely observed in multisystem LCH. We describe an exceptional case of hepatic LCH in an adult, mimicking AMA-negative PBC, preceding the diagnosis of multisystem LCH. Methods A 65-year-old man presented with intermittent pruritus, weakness, dyspnea, fever, and chills that have been progressive for 4 years. Physical examination was unremarkable. Laboratory work revealed elevated alkaline phosphatase (471 U/L; ref 40-120 U/L), GGT (271 U/L; ref 0-41 U/L), total bilirubin (2.0 mg/dL; ref 0.0-1.2 mg/dL), and direct bilirubin (1.1 mg/dL; ref 0.0-0.3 mg/dL). Indirect bilirubin, AST, and ALT were within normal limits. Liver biopsy was performed. Results Liver biopsy showed lobular and portal nonnecrotizing granulomas with one “florid duct lesion” with duct injury, suggestive of PBC. Tests for autoimmune diseases including AMA were negative. ERCP was negative for biliary obstruction. One month after the liver biopsy, he developed flaking, red, and burning rash on the right scalp, forehead, and epigastric skin. A skin biopsy at an outside institution revealed dermal and epidermal infiltration of CD1a-positive histiocytes with indented nuclei and pale eosinophilic cytoplasm, consistent with LCH. Subsequent reexamination of the liver biopsy showed that the histiocytes within the florid duct lesion were positive for CD1a and S-100, while the remaining granulomas were negative. The following day, a small focus of LCH was noted in his gastric biopsy performed for gastritis symptoms. Conclusion Hepatic LCH may mimic AMA-negative PBC histologically and clinically, and may present as a harbinger of multisystem LCH. While rendering the diagnosis would be challenging without prior history of LCH and with focal involvement, awareness of such presentation and communication with clinical colleagues may be helpful.

Background: A Grey 12-year-old Arabian endurance horse gelding was referred to the SHS Veterinary Center for anorexia, mild colic of 5 days duration, and melena of 1 day duration. The owner reported recurring colic, 12 episodes of mild colic in the previous year. Methods: On admission, vital signs were within normal limits and body condition score was estimated to be 3/9. Results: Packed cell volume (PCV) was 28% [reference range (RR): 31% to 47%] and plasma total protein was 58 g/L (RR: 60 to 80 g/L). Hematochezia was observed. Abdominal ultrasound examination detected no abnormalities. Over the next 12 h, the horse experienced hematochezia and several mild episodes of colic and death. A necropsy was performed. A mass arising from the right dorsal ascending colon near the base of the cecum and extending transmurally from the colonic mucosa into the mesocolon was a 8 cm × 5 cm × 8 cm firm, homogenous, tan mass. The portion of the mass that extended into the colonic lumen was pedunculated, with an ulcerated surface. The adjacent segments of colon were markedly reddened and edematous. Histologically, the mass was comprised of large interweaving sheets of small, spindle cells with ill-defined cell borders embedded in abundant myxomatous matrix. Tumor cells contained scant eosinophilic cytoplasm and oval to elongate nuclei with finely stippled chromatin and inconspicuous nucleoli. Mitotic figures were rare (1/10) high power fields. Tumor infiltrated between the muscularis interna and the muscularis externa at the myenteric plexi. Conclusion: Gross and histologic appearance, were consistent with a diagnosis of gastrointestinal stromal tumor.

Abstract Background Cardiac Hibernomas are very rare benign tumors and usually remain asymptomatic. Neonatal cardiogenic shock due to cardiac tumors is extremely very rare. Until this date a few cases of cardiac hibernoma have been reported in the literature. Transthoracic echocardiography help in the differential diagnosis, but the definitive diagnosis is histological. The management strategy is not clearly codified. The Aim is to report and discuss the clinical features of a cardiac Hibernoma and review the relevant literature. Case presentation We describe a case of a 2-day-old Caucasian full-term male neonate admitted in neonate intensive care with cardiogenic shock, having fluid resuscitation and inotropic drugs. Ventilatory support was started immediately with the subsequent reestablishment of normal blood pressure. Then he was transferred to the echocardiography laboratory. Transthoracic echocardiography showed two echogenic masses in the right atrium and right ventricle. The masses were extended to the pulmonary trunk. Pulmonary artery flow measurements showed the presence of pulmonary and tricuspid obstruction. Surgery was rapidly considered since the baby was hemodynamically unstable. Intraoperative evaluation showed a mass embedded in the interventricular septum that occupy the right ventricular cavity and the right atrium. The tumor involved also the chordae of the tricuspid. Partial resection was done. Tricuspid valve repair was performed by construction of new chordae from the autologous pericardium. The specimen was sent for histopathological analysis. The baby died immediately after surgery. Histological examination of the surgical specimen revealed clear multivacuolated cells filled with lipid droplets and granular intense eosinophilic cytoplasm which confirms the diagnosis of Hibernoma. Conclusion Cardiac Hibernomas are rare benign tumors. The prognosis and treatment strategy is closely dependent on the location, initial clinical presentation and possible complications. The prognosis can be unfavorable if the tumor was obstructive and infiltrate the myocardium.

AbstractInflammatory myofibroblastic tumors (IMTs) in the head and neck region are common, but those with sympathetic trunk involvement are extremely rare. Here we present a case of cervical sympathetic trunk-centered IMT which is also accompanied by ipsilateral carotid artery, internal jugular vein, and vagus nerve involvement. The patient initially complained of an episodic painful swelling on the right side of the neck and underwent surgery. Preoperative and postoperative serum IgG4 level during 3-year follow-up time is within normal limits. Immunohistochemical study of the tumor has also revealed negativity to IgG4. Postoperative first bite syndrome (FBS) was observed. Surgery seems to be first-line therapy in the patient with IgG4-negative IMT.

Plexiform neurofibromas are benign tumors that tend to occur in patients suffering from neurofibromatosis type 1 (NF-1). This report addresses a rare case where the tumor affected the parotid gland, deriving almost exclusively from the peripheral portion of the facial nerve. A 6-year-old male was referred to us complaining about a gradually enlarging swelling over the right parotid area. Imaging localized the lesion to the superficial lobe of the parotid gland, suggesting a neurofibroma. Cosmetic disfigurement and a functional deficit led us to perform complete surgical resection. Meticulous surgical dissection as well as auriculotemporal nerve origin made complete extirpation possible with almost zero morbidity and ensured alleviation of both aesthetic impairment and pain. This is the first case of an intraparotid PN in a pediatric NF-1 patient, which originated from branches of the auriculotemporal nerve and particularly from fibers of the autonomic nervous system. Radical surgical excision was decided according to established decision-making algorithms.

A patient who suffered a transient global amnesia (TGA) attack underwent regional cerebral blood flow (rCBF) SPECT imaging and neuropsychological testing in the acute phase, after one month and after one year. Neuropsychological testing in the acute phase showed a pattern of anterograde and retrograde amnesia, whereas memory was within age normal limits at follow up. SPECT data were analysed with a within subject comparison and also compared with those of a group of healthy controls. Within subject comparison between the one month follow up and the acute phase detected increases in rCBF in the hippocampus bilaterally; further rCBF increases in the right hippocampus were detected after one year. Compared to controls, significant hypoperfusion was found in the right precentral, cingulate and medial frontal gyri in the acute phase; after one month significant hypoperfusion was detected in the right precentral and cingulate gyri and the left postcentral gyrus; after one year no significant hypoperfusion appeared. The restoration of memory was paralleled by rCBF increases in the hippocampus and fronto-limbic-parietal cortex; after one year neither significant rCBF differences nor cognitive deficits were detectable. In conclusion, these data indicate that TGA had no long lasting cognitive and neural alterations in this patient.

Abstract Aim To highlight the importance of appropriate imaging modalities for abnormal clinical presentations. Method Xyo woman presented with severe right upper-quadrant pain to the emergency department. Prior history of colicky abdominal pain for 1 year, right-sided nephrectomy and hypertension. She stated that the current epsiode of pain was the worst so far, becoming more persistent, prompting her to call an ambulance. Cholecystitis was suspected, so a Computed Tomography abdomen/pelvis was performed. A dilated, inflamed gallbladder was noted in contact with the right psoas major, with what appeared to be an abscess in the right psoas major. Results A Magnetic Resonance Cholangiopancreatography was performed, which demonstrated that the aforementioned abscess was in fact a large cavity within the psoas major, containing up to 15 gallstones. Cholelithiasis was also seen, with common bile duct dilatation and evidence of a common bile duct stone. An Endoscopic Retrograde Cholangiopancreatography was performed, and X recovered well post-procedure with analgesia and antibiotics. Conclusions Acute cholecystitis/intra-abdominal gallstones may result in abscess/cavity formations and abnormal biliary clinical presentations. It is important therefore to fully investigate abnormal hepatobiliary imaging with multiple imaging modalities to allow for accurate diagnosis and appropriate further management of presentations.

We report an interesting case of extraovarian, primary seromucinous cystadenoma, which presented as a mesenteric cyst. A 31-year-old woman came with complaints of lower abdominal pain for 2 years, which is intermittent and aggravated during the menstrual cycle. On examination, her vitals were within normal limits; per abdominal examination revealed 7×7 cm mass in the right lumbar and right hypochondrium with well-defined margins. A Contrast-enhanced whole abdomen done showed a thin-walled of cyst of size 7×8×9 cm in the right lumbar region abutting and replacing the mesenteric border of ascending colon suggesting of mesenteric cyst. Patient underwent laparoscopic excision of mesenteric cyst. Histopathology revealed seromucinous cystadenoma without ovarian stroma.

Abstract Introduction/Objective Classic primary sclerosing cholangitis (PSC) involves extrahepatic and/or intrahepatic biliary ducts with segmental biliary strictures and dilatations that often allow the diagnosis to be made via cholangiogram. Small duct PSC (sdPSC) is a rare subtype that presents similarly with a cholestatic pattern of injury, yet due to the small size of involved ducts, a cholangiogram is non-diagnostic and diagnosis is dependent on clinical suspicion and liver biopsy. The histopathological features of sdPSC are often subtle and may easily be overlooked. Diagnosis of this entity- though difficult- is important, as early recognition can facilitate the identification of associated disease processes and life-threatening complications. Methods/Case Report We encountered a 33-year-old female presenting with intermittent pruritis, episodes of jaundice, and persistently elevated alkaline phosphatase who was misdiagnosed with only fatty liver at an outside institution. Evaluation with MRCP showed no abnormalities within the biliary tract and a liver biopsy was performed to aid in the diagnosis. The H&E and trichrome findings of atrophic bile ducts and some peribiliary sclerosis were extremely subtle and may have been overlooked without clinical suspicion. Cytokeratin 7 (CK7) highlighted cholangiolar metaplasia in hepatocytes and the bile ductular reaction that occurs in cholestatic disease states. A Rhodamine copper stain showed periportal deposition suggestive of chronic biliary obstruction. Use of CK7 and copper stains supported the presence of chronic biliary injury and suboptimal bile flow, confirming the diagnosis of sdPSC. Results (if a Case Study enter NA) NA Conclusion Diagnosis of sdPSC has historically relied on H&E and trichrome stains. In this case, the findings on H&E and trichrome stains were non-diagnostic, while the use of CK7 and copper stains confirmed the diagnosis of sdPSC. We recommend using CK7 and copper stains to evaluate for sdPSC.

Adrenal hemangioma is an extremely rare benign and non-functioning neoplasm of the adrenal gland. We report a case of a 71-year-old woman admitted for intermittent abdominal pain and abdominal distension associated with vomiting and chronic constipation for 5 years. Physical examination revealed a large abdominal mass. Both computed tomography scan and magnetic resonance imaging suggested hemangioma in the right lobe of the liver. Laboratory examinations and tumour markers were within normal limits, except for hypochromic microcytic anemia. The mass was removed intact by conventional surgery and histopathology revealed a cavernous hemangioma of the adrenal gland with no signs of malignancy. Surgical resection was curative, with no recurrence at the 2-year follow-up.

Purpose:Glomus tumours are characteristically benign solitary tumours. At our knowledge, about 23 reports are present in literature regarding the malignant counterpart, but only a minority developed metastases. We describe a locally aggressive glomus tumour with lymphnode metastasis.Patient:The patient was a 40 year-old man presenting a 1.5-cm lesion on the right wrist incompletely excised and a recurrent tumour, 4 × 2 cm in size, removed after 9 months, for which he received radiotherapy. After 2 years he developed an axillary lymphnode metastasis.Results:Histologically, both tumours (primary and metastasis) were similar. There were sheets and nests of uniform small cells with scant eosinophilic cytoplasm and round to polygonal nuclei; there was some degree of pleomorphism and the mitotic index was high (up to 18 m/10 HPF). The tumour cells were positive for vimentin and smooth muscle actin, but negative for desmin, NSE, Factor VIII, chromogranin, cytokeratin. Remarkably, in the primary, the cells strongly expressed p53 (70%) and MIB-1 (35%).Discussions:In many reported malignant cases, the histology of the tumour cells suggested that they were malignant, yet the clinical course has been benign. Carefully reviewing the literature, it seems that actually we have enough histological criteria to identify the cases with biological adverse outcome. Those unfortunate cases behave as high grade sarcomas and therefore may deserve an aggressive therapeutic treatment.
