[Ab] Resumo:RATIONALE: Ghost cell odontogenic carcinoma (GCOC) is a rare malignant odontogenic tumor with aggressive growth characteristics. PATIENT CONCERNS: A 41-year-old Chinese male visited our hospital in 2013, with a 4-month history of bloody purulent rhinorrhea with a peculiar smell in the right nasal cavity. DIAGNOSES: The patient suffered from recurrent GCOC with suspected cholesterol granuloma of the maxillary sinus. The patient was incorrectly diagnosed with a calcifying epithelial odontogenic tumor at his first recurrence. Physical examination, radiological examination, and histopathology were used to identify GCOC. INTERVENTIONS: Considering the recurrence of GCOC and poor effects of single surgery, postoperative adjuvant chemotherapy and concurrent chemoradiotherapy were performed after radical surgical excision. OUTCOMES: So far, no significant evidence has suggested recurrence or metastasis after a long-term follow-up. LESSONS: We advocate wide surgery with clean margins at the first accurate diagnosis. Combined modality therapy could be taken for the recurrent GCOC. We expect to provide a new treatment strategy to prevent the growth of this neoplasm.

[Ab] Resumo:Pencil core granulomas are still infrequently reported in the literature. A 67-year-old woman presented with a 4mm hard blue subcutaneous nodule on the forehead. She remembered being injured with a pencil tip about 60 years before. The subcutaneous nodule was excised, which microscopically revealed a foreign body reaction with histiocytes containing fragmented coarse black particles. We diagnosed pencil-core granuloma based on the patient's history of pencil tip injury and histological examination findings.

[Ti] Título:Handheld In Vivo Reflectance Confocal Microscopy for the Diagnosis of Eyelid Margin and Conjunctival Tumors.

[La] Idioma:eng
[Ab] Resumo:Importance: The clinical diagnosis of conjunctival and eyelid margin tumors is challenging, and new noninvasive imaging techniques could be valuable in this field. Objective: To assess the diagnostic accuracy of handheld in vivo reflectance confocal microscopy (IVCM) for the diagnosis of eyelid margin and conjunctival tumors. Design: A prospective observational study was conducted at University Hospital of Saint-Etienne from January 2, 2011, to December 31, 2016 (inclusion of patients until December 31, 2015, and follow-up until December 31, 2016). A total of 278 consecutive patients with eyelid margin or conjunctival lesions were included. Conjunctival lesions were diagnosed with a conventional clinical examination using a slitlamp and by handheld IVCM. Final diagnoses were established by histopathologic examination for 155 neoformations suspicious for being malignant through clinical and/or IVCM examination that were excised and on follow-up of 12 months or longer for the remaining 140 lesions. Main Outcomes and Measures: Sensitivity, specificity, and positive and negative predictive values for malignant tumors of the conjunctiva and eyelid margin were calculated using clinical examination with slitlamp and handheld IVCM. Results: In the 278 patients (136 [48.9%] females; mean [SD] age, 59 [21] years), a total of 166 eyelid margin and 129 conjunctival lesions were included in the analysis. Of the 155 excised neoformations with a histopathologic diagnosis, IVCM showed higher sensitivity compared with clinical examination conducted with the slitlamp for malignant tumors of the eyelid margin (98% vs 92%) and conjunctiva (100% vs 88%). The specificity for malignant eyelid margin tumors was higher for IVCM than for slitlamp examination (74% vs 46%), but slightly less for malignant conjunctival tumors (78% vs 88%). Analysis of all neoformations (155 excised and 140 in follow-up) confirmed these differences in the diagnostic accuracy of the clinical examination and IVCM. The presence of hyperreflective Langerhans cells mimicking malignant melanocytes was the main cause for misdiagnosis of malignant conjunctival tumors with IVCM. Conclusions and Relevance: Handheld IVCM could be a useful tool for the identification of malignant conjunctival tumors. Further studies are required to confirm the usefulness of this device and identify possible features that can differentiate Langerhans cells from malignant melanocytes to prevent the misdiagnosis of melanoma using IVCM.

[Ab] Resumo:A 66-year-old woman underwent right lower lobectomy and partial resection of the middle lobe for Stage I A double lung cancer. Five years after the operation, a routine computed tomography (CT) scan showed a mass on the staple line at the middle lobe. The mass was enlarged on CT scan after 6 months. A definitive diagnosis could not be made by bronchoscopic examination and fluoro-2-deoxy-glucose(FDG)/positron emission tomography( PET)-CT showed FDG uptake in the mass( early phase:SUVmax=3.24, late phase:SUVmax=4.31). Local recurrence of lung cancer was not completely denied, and right middle lobectomy was performed. Histopathologically, the resected specimen revealed granuloma with foreign body reaction. We should keep in mind the possibility of granuloma as differential diagnosis of lung cancer when using stapler.

[Ab] Resumo:With a continuing increase in the number of tattoos performed worldwide, the need to treat tattoo complications is growing. Earlier treatments of chronic inflammatory tattoo reactions were dominated by a medical approach, or with no active intervention. In this chapter, we will address modern surgical approaches applied to situations when medical treatment is inefficient and lasers are not applicable. Dermatome shaving is positioned as first-line treatment of allergic tattoo reactions and also indicated in a number of other tattoo reactions, supplemented with excision in selected cases. The methods allow fundamental treatment with removal of the culprit pigment from the dermis. The different instruments, surgical methods, and treatment schedules are reviewed, and a guide to surgeons is presented. Postoperative treatments and the long-term outcomes are described in detail. An algorithm on specialist treatment and follow-up of tattoo reactions, which can be practiced in other countries, is presented.

[Ab] Resumo:Tattoos, and tattoo complications as well, are colorful and visually flashy. A clinical outlook provides important clues to diagnosis by pattern recognition. This atlas,which is a report of 79 case illustrations, is made as a practical tool and vade mecum for the clinician. The atlas can be used in the office and as a bedside tool. It includes characteristic photos, and each case is accompanied with a brief medical history, a comment with learning points, the final diagnosis, and a review of therapeutic options. This spectrum of cases illustrates the different diagnostic entities according to the newly proposed Bispebjerg University Hospital ('Tattoo Clinic') diagnostic system of tattoo complications, a system reported to the 11th revision of the WHO disease classification system. Cases include allergies predominantly seen in red tattoos manifesting the characteristic patterns of plaque elevation, excessive hyperkeratosis, ulcerating reactions, urticaria, and generalized skin rash. Each type of reaction has typical clues to diagnosis and a typical disease course. 'Cross-sensitivity' allergic reactions in old tattoos of the same color as the trigger tattoo are also illustrated. Reactions in black tattoos are dominated by a pattern with papulonodular reactions, which are nonallergic anddue to pigment agglomeration in the skin. Reactions may be granulomatous and a marker of systemic sarcoidosis, sometimes associated with a general outbreak in the skin in black tattoos, e.g. 'rush phenomenon'. Bacterial infections are also illustrated. The technical hazards of tattooing and sequels as well as unwanted effects of tattoo removal by lasers are shown along with severe scarring following tattoo removal by caustics. This atlas is a tutorial in modern medical and surgical treatments of tattoo complications.

[La] Idioma:eng
[Ab] Resumo:Diagnosis of tattoo complications is a multi-facetted field since many clinical entities and disease mechanisms are represented. Infections, allergies, and pigment foreign body reactions with granuloma are the major groups. The clinician needs a structured approach to diagnosis and an armamentarium of standard tests. Diagnosis primarily builds on patient history, objective clinical examination, and punch biopsy, supplemented with microbiology testing, ultrasound scanning, and clinical photography. Evaluation of allergic tattoo reactions and allergy to pigments by patch testing is not applicable and has a falsely negative outcome except for the diagnosis of allergy to metals and preservatives. Simple inspection of raw punch biopsies from chronic tattoo reactions, preferably evaluated with stereo microscopy, provides important information about the density and the local distribution of tattoo pigment in the dermis and changes of micro- anatomical skin structures. Histology may show subtle structural changes, but traditional patterns (lichenoid reaction, pseudolymphoma, granuloma, and pseudoepitheliomatous epidermal hyperplasia) are of little or no help in the diagnosis since the patterns overlap and have no distinct clinical correlates. Histology cannot separate allergic and nonallergic reactions. However, granulomatous reaction and sarcoid granuloma are significant findings since papulonodular reaction of black tattoos and sarcoidosis are strongly associated with each other. 20-MHz ultrasound scanning is important for noninvasive imaging and characterization of inflammatory tattoo reactions and can be used preoperatively as guide to treatment. Electron microscopy can visualize pigment particles in tissues, cells, and tattoo inks. Chemicals of pigment in tissues and in tattoo inks can be analyzed by high-performance liquid chromatography, mass spectroscopy, and Raman spectroscopy.

[Ab] Resumo:OBJECTIVE: Oral pulse granuloma (OPG) is an oral inflammatory lesion characterized by the presence of hyaline rings with numerous multinucleated giant cells. The etiopathogenesis of this lesion is thus far unclear, as is the composition of the hyaline rings. Our aim was to investigate whether the hyaline rings contain cellulose. STUDY DESIGN: Using a newly developed staining method for cellulose, we studied 18 histologic samples diagnosed as OPG, in addition to 3 samples originally diagnosed as "normal" foreign body reactions. In our study, visualization of cellulose is based on its specific binding to the carbohydrate binding module of ß-1,4-glycanase. RESULTS: All samples diagnosed as OPG were positive for cellulose staining localized in hyaline rings. In addition, 1 lesion (of 3), first diagnosed as a foreign body reaction without the presence of hyaline rings, was positive for cellulose by horseradish peroxidase staining. CONCLUSIONS: We show for the first time that cellulose is present in OPG lesions, indicating that cellulose might be the initial cause of formation of these lesions.
