Paget’s disease of the nipple diagnosed by MRI

Background: Paget’s disease of the breast is a rare manifestation of breast carcinoma. Case report: The patient presented with a red lesion of the left nipple–areola complex. Breast physical examination, ultrasonography and mammography were normal bilaterally. Magnetic resonance imaging (MRI) correctly depicted Paget’s disease of the nipple. Before surgery the patient underwent biopsy of the lesion that showed Paget’s disease of the breast associated with an underlying ductal carcinoma in situ. The patient underwent left mastectomy and unilateral axillary lymph node dissection. The patient refused the breast-conserving surgery because she was afraid that she could have a recurrence of the carcinoma. Microscopy of the lesion confirmed the MRI diagnosis. Conclusion: MRI was very useful and accurate to diagnose Paget’s disease of the breast without palpable mass, ultrasonographic and mammographic findings.

Oncocytic Schneiderian papillomas: Clinical behavior and outcomes of the endoscopic endonasal approach in 33 cases

The purpose of this study was to evaluate the clinical behavior of oncocytic Schneiderian papillomas in relation to the rate of malignant transformation and recurrences and to report the long‐term results of the endoscopic endonasal treatment.

Correlation between nasal mucociliary clearance time and gastroesophageal reflux disease : our experience on 50 patients

OBJECTIVES It is increasingly suggested that gastroesophageal reflux disease (GERD) could play an important role in chronic rhinosinusitis. The aim of our study was to evaluate the nasal mucociliary clearance time in GERD patients and if any correlations could be assumed. METHODS Fifty GERD patients endoscopically diagnosed underwent an ear, nose and throat evaluation. The saccharin test and the 20-Item Sino-nasal Outcome Test (SNOT-20) were administered to 50 participants who correspond to our inclusion criteria. The saccharin test is a validated proof to verify the nasal mucociliary clearance time and the SNOT-20 is a disease-specific, health-related quality of-life questionnaire widely used for the assessment of rhinosinusitis. RESULTS Thirty-seven (74%) patients showed a significant increment in their saccharin test values in comparison with the others subjects (23.79+/-5.58 vs 8.15+/-2.06min; P=0.0001). This group of patients reported only typical gastroesophageal symptoms (GES) without any other complaint. Gastroesophageal endoscopic findings revealed some interesting and unexpected results in this subgroup. The remainder of patients considered (13/50; 26%) showed normal values for nasal mucociliary clearance time and they referred only typical extraesophageal symptoms (EES). In any case and in both groups rhinosinusitis complaints were present. The SNOT-20 test results were normal in all patients even if a significant difference for GES group could be highlighted (19.3 vs 7.4; P<0.005). CONCLUSION This study supports the assumption of possible and important correlations between nasal mucociliary clearance time and GERD. GERD could be an altering factor for nasal function also in absence of laryngo-pharyngeal symptoms although to verify this interesting hypothesis more validated data are necessary.

Lymph Node Axillary Metastasis from Occult Contralateral Infiltrating Lobular Carcinoma Arising in Accessory Breast: MRI Diagnosis

Abstract:  We describe a case of right axillary lymph node metastasis of an occult infiltrating lobular carcinoma arising from accessory mammary gland of the left upper anterior chest wall. Ultrasonography and mammography were normal bilaterally. Magnetic resonance imaging (MRI) revealed a 3.34 cm inhomogeneous lesion. Then, core biopsy under ultrasound guidance demonstrated a typical infiltrating breast lobular carcinoma. To our knowledge, this is the first case reported in the literature of an axillary lymph node metastasis from an occult contralateral infiltrating lobular carcinoma of the accessory breast tissue. MRI was useful for assessing the lesion of the accessory breast tissue.

Bilateral oncocytoma of the parotid gland

Oncocytic neoplasms are a group of rare tumours that mostly affect the parotid gland (80%), sometimes affect the submandibular gland (9%) and rarely affect the intraoral minor salivary glands. The incidence of oncocytic neoplasms represents ≈1% of parotid neoplasms and bilateral presentation is very rare. Herein we describe a single case involving bilateral presentation of oncocytoma of the parotid glands.

Primary orbital eosinophilic angiocentric fibrosis with intranasal extension

Eosinophilic angiocentric fibrosis is a chronic, idiopathic disorder that usually involves the upper respiratory tract and features progressive submucosal perivascular fibrosis of unknown etiology. To our knowledge, only 5 cases of eosinophilic angiocentric fibrosis with primary orbital involvement have been reported.

Mammography and Ultrasound Imaging of Preinvasive and Invasive Canine Spontaneous Mammary Cancer and Their Similarities to Human Breast Cancer

Understanding the evolution of proliferative breast disease such as atypical hyperplasia and carcinoma in situ is essential for clinical management of women diagnosed with these lesions. Therefore, an animal model that faithfully represents human breast disease in every aspect from spontaneity of dysplasia onset, histopathologic features, and genetics to clinical outcome is needed. Previously, we studied canine spontaneous atypical hyperplasia and ductal carcinoma in situ (low, intermediate, and high grade) and reported their similarities to human lesions in histopathologic and molecular features as well as prevalence. To further validate the resemblance of these lesions to humans, we examined their mammographic and sonographic characteristics in comparison with those of humans as well as the potential of the human Breast Imaging Reporting and Data System (BI-RADS) to predict canine disease. Nonlesional, benign, and malignant mammary glands of dogs presented to Sassari Veterinary Hospital were imaged using mammography and ultrasonography. The images where then analyzed and statistically correlated with histopathologic findings and to their similarities to humans. Our results showed that canine mammary preinvasive lesions, benign, and malignant tumors have mammographic abnormalities, including the presence, pattern, and distribution of macrocalcification and microcalcification, similar to their human counterparts. BI-RADS categorization is an accurate predictor of mammary malignancy in canine, with 90% sensitivity and 82.8% specificity. The similarities of mammographic images and the ability of BI-RADS to predict canine mammary malignances with high specificity and sensitivity further confirm and strengthen the value of dog as a model to study human breast premalignancies for the development of prognostic biomarkers.

A novel endoscopic technique for long‐term patency of cholesterol granulomas of the petrous apex

Cholesterol granulomas (CGs) are rare benigncystic lesions containing cholesterol crystals in a glue-like fluid and are frequently found in the petrous apex(PA) and in the nearby anatomical area. The goldstandard treatment of PA CG counts on its surgicaldrainage and ventilation to prevent recurrence. Differ-ent surgical approaches have been described in the pastto achieve drainage of these lesions, either through lat-eral, or more recently through an endoscopic endonasalcorridor.

Mediastinal abscess and esophageal stricture following voice prosthesis insertion.

The use of a tracheo-esophageal voice prosthesis is a well-established procedure to restore the voice in total laryngectomees. The insertion of the prosthesis is not a risk-free procedure, various complications having been reported especially in irradiated patients. Here described is a case of an esophageal rupture after secondary tracheo-esophageal puncture with mediastinal abscess in a patient previously treated with pharyngo-laryngectomy and subsequent radiotherapy for a left pyriform sinus carcinoma, which required immediate surgical drainage through a left cervical approach. Few weeks after surgical drainage an esophageal stricture at the site of the rupture developed, which was only temporarily resolved after the insertion of biodegradable esophageal stents, followed by re-stenosis once the reabsorption of the stent took place.

Pediatric follicular dendritic cell sarcoma of the head and neck: a case report and review of the literature

OBJECTIVE Follicular dendritic cell sarcoma is a rare disease with a non-specific and insidious presentation that is further complicated by difficult diagnostic and therapeutic assessment. METHODS The database PubMed was searched for reports of follicular dendritic cell sarcoma between 1986 (first case published) and 2012. All of the articles presenting informations regarding one or more cases of follicular dendritic cell sarcoma of the head and neck region, in patients less than 18 years of age, were included. The reference lists for pertinent reports were also scanned to ensure that all relevant literature was included. RESULTS We present a case of a 14 year-old girl, with a 2-month history of a right-sided level II neck mass. After a carefull radiologic evaluation the mass was resected combined with a right selective neck dissection. Histology with immunohistochemical staining was positive for follicular dendritic cell sarcoma. No recurrence was seen after 31 months follow-up. The literature search identified six more cases of pediatric follicular dendritic cell sarcoma of the head and neck. This is the first female patient with follicular dendritic cell sarcoma in the pediatric population. CONCLUSIONS Current treatment of head and neck follicular dendritic cell sarcoma consists of wide radical resection, with associated radiotherapy or chemotherapy only for cases with aggressive disease such as extracapsular invasion, tumor size ≥6 cm or after failure of the first-line surgical treatment.
