ABSTRACT
INTRODUCTION: Amyloidosis is an uncommon disease caused by the deposition of amyloid fibrils in tissues. This disease does not usually require surgical intervention, which could be warranted in the presence of complications such as bleeding, obstruction, or perforation. We present a case of primary amyloidosis of the colon in a patient affected by polymyositis who underwent Hartmann's procedure after a spontaneous colonic perforation. After 2 months of well-being, the patient underwent two consecutive surgical procedures for stenosis of the ostomy orifice. AREAS COVERED: A review of the literature has been performed, gathering case reports highlighting the distribution of this disease by age, gender, location, and treatment when available. EXPERT COMMENTARY: Gastrointestinal amyloid disease is a rare condition, and it could be considered among the rare causes of intestinal perforation. Timely surgical management is often necessary.

Objetivo. La medida de la velocidad de onda de pulso (VOP) en las grandes arterias es un indicador de riesgo vascular. Nuestro objetivo fue identificar el índice de VOP entre brazos y piernas que mejor se correlaciona con la cuantificación del calcio coronario (CCC) y compararlo con otros métodos. Material y métodos. A 81 pacientes sin enfermedad vascular, a los que se les había determinado la CCC, se les midió el grosor íntima-media carotídeo (GIM), la VOP carótido-femoral (VOP cf) con COMPLIOR y la VOP en brazos y piernas con un dispositivo propio (VOPITB: VOP índice tobillo brazo). Resultados. La VOP de pierna menos brazo (VOP P-B) determinado con VOPITB fue el índice mejor correlacionado con la CCC (r=0,401, p<0,001). Las correlaciones del GIM y VOP cf con la CCC fueron: r=0,366, p=0,001 y r=0,385, p=0,001, respectivamente. Con referencia a una puntuación de la CCC mayor de 100 como marcador de arterosclerosis coronaria significativa, las áreas bajo la curva fueron para VOP P-B de 0,721 (p=0,002), GIM: 0,758 (p<0,001) y VOP cf: 0,636 (p=0,058). Conclusiones. En pacientes sin enfermedad vascular la VOP P-B medida con VOPITB parece ser el índice que mejor correlaciona con la CCC. Esta asociación es comparable con la que mantienen el GIM y la VOP cf con la CCC. VOPITB es un dispositivo fácil de manejar que puede contribuir a mejorar la estratificación del riesgo vascular (AU)
Objective. The pulse wave velocity (PWV) in the great arteries is an indicator of vascular risk. Our objective was to identify the PWV index between the arms and legs that best correlates with the coronary calcium quantification (CCQ) and to compare it with other methods. Material and methods. Eight-one patients without vascular disease underwent the following measurements: CCQ; carotid intima-media thickness (IMT); carotid-femoral PWV (cfPWV), using COMPLIOR; and PWV in the arms and legs, with our own device (abiPWV, ankle brachial index PWV). Results. The difference in PWVs between the leg and arm (l-a PWV) measured with abiPWV was the index that best correlated with CCQ (r=0.401, P<.001). The correlation between IMT and CCQ and between CF-PWV and CCQ were r=0.366, P=.001; and r=0.385, P=.001, respectively. For a CCQ score higher than 100 as a marker of significant coronary arteriosclerosis, the areas under the curve for l-a PWV, IMT and cfPWV were 0.721 (P=.002), 0.758 (P<.001) and 0.636 (P=.058), respectively. Conclusions. For patients without vascular disease, the l-a PWV measured with abiPWV appears to be the index that best correlates with the CCQ. This association is comparable to that between IMT and CCQ and between cfPWV and CCQ. The abiPWV is an easy-to-use device that can help improve vascular risk stratification (AU)

ABSTRACT
Ghost cell odontogenic carcinomas are rare neoplasms that arise in the maxillary bones either from a calcifying odontogenic cyst or de novo. They are aggressive locally and can metastasize. We report herein a case of a ghost cell odontogenic carcinoma arising in the mandible of a Caucasian male 86 years of age. We have described the clinical and radiographic features, histological characteristics, immunohistochemistry findings, and surgical treatment. We especially focused on how Ki-67 expression guides the treatment choice. Finally, we reviewed 32 cases described in the literature and compared them with the cases described up until 2014 to help clinicians identify the diagnostic characteristics of and select appropriate treatment modalities for ghost cell odontogenic carcinomas.

AIMS: The presence of ground glass hepatocytes in a liver biopsy may be related to different conditions, including fibrinogen storage disease. Three types of fibrinogen storage disease have been described, namely types I, II and III. Type I is an hereditary hypofibrinogenaemia genetically characterized by a mutant variant of the fibrinogen molecule designated as fibrinogen Brescia, consistent with a gamma284 Gly-->Arg mutation. Only rare cases of types II and III fibrinogen storage disease have been described. The purpose of the present paper is to describe two cases of fibrinogen storage disease without associated hypofibrinogenaemia, which appeared during acute infectious diseases. METHODS AND RESULTS: Both patients were female, aged 77 and 73 years, who developed high transaminases during an infectious disease. In each case blood coagulation tests were within the normal range, and despite clinical and laboratory investigations no possible cause for liver disease could be found. Liver biopsies were performed; in both cases weakly eosinophilic cytoplasmic inclusions were observed. Using immunohistochemistry the inclusions were found to be due to fibrinogen accumulation. At ultrastructural level features corresponding to type II inclusions were observed. Molecular studies, performed in case 2, excluded the mutation typical of type I fibrinogen storage disease. Both patients also presented features of chronic hepatitis. In case 1, giant cell granulomas were additionally present. No close relatives of the patients presented any clinical or laboratory features of liver disease. In both patients altered liver function test values gradually, spontaneously, returned to within normal ranges after infectious disease was resolved. CONCLUSIONS: These cases suggest that, on rare occasions, hepatocytes may accumulate fibrinogen during an infectious disease.

A case of hyperkeratosis follicularis et parafollicularis in cutem penetrans Kyrle's disease in a 41-year-old woman is described. It was a recurrence of a lesion surgically removed and originally diagnosed as invasive squamous cell carcinoma. Kyrle's disease is a rare dermatosis and should not be confused with neoplastic conditions i.e. squamous cell carcinoma. Pathologists should be aware of such conditions in order to avoid misdiagnosis, which can imply over treatment for the patient.

Here we describe a case of gastrointestinal autonomic nerve tumor (GANT) arosen in a patient with von Recklinghausen's disease. To the best of our knowledge, only four other similar cases have been previously reported in the literature. Histologically, the tumour was composed of spindle shaped cells arranged in short bundles. The neoplastic cells had pleomorphic nuclei and numerous mitoses. Immunohistochemical investigation displayed evidence of neural differentiation. Neoplastic cells were diffusely anti-synaptophysin, anti-neuron specific enolase and anti-vimentin positive. The clinicopathological features of the present case are described and discussed together with those of the other previously reported cases.

We have studied 25 thymomas by both immunohistochemistry and in situ hybridization for the presence of growth hormone (GH)-producing cells. Our results indicate that 1) GH-immunoreactive cells were present in 13 of 17 thymomas of cortical and predominantly cortical type but not in medullary (spindled) thymomas (n = 3) or low- to high-grade thymic carcinomas (n = 5), 2) GH-positive cells were mainly located at the periphery of the neoplastic lobules, at the periphery of the perivascular spaces and in the areas of medullary differentiation, 3) cells containing GH mRNA appeared at locations similar to those of GH-immunoreactive cells, and 4) GH-immunoreactive material was present only in the epithelial cell component as revealed by immunoelectron microscopy. In conclusion, this paper demonstrates the occurrence of GH-producing cells in noncarcinoid thymic tumors. The relevance of GH in thymoma cell biology requires additional investigations.
