Abortive aphthous-like oral lesions: an underreported initial presentation of pemphigus vulgaris

Oral soft tissue biopsy surgery: Current principles and key tissue stabilization techniques

There are different kinds of benign and malignant lesions in the oral cavity. Clinically, definite diagnosis can be confirmed only by doing adequate surgical biopsy and subsequent histopathological examination. Inadequate biopsy technique, unsuitable selection of the location for biopsy, inappropriate tissue handling and record of patients' information may lead to artifacts and misdiagnosis by the oral pathologists. Soft tissue stabilization is a challenge during oral surgery procedures. It needs the cooperation of operator, assistants, and patients to overcome the difficulty and ensure the successful outcome. In this article, we reviewed the procedures for clinical surgical biopsy, and raised three current tissue stabilization methods including fingers and gauze stabilization, stabilization with chalazion forceps and adapted instruments, and stabilization with retraction sutures. Moreover, some limitations were also presented. Clinician should examine the clinical characteristics of the oral lesion, the surrounding anatomical structures, and their own clinical experience and preference to select the appropriate tool. More understanding of these biopsy and tissue stabilization methods can effectively improve the biopsy procedures and obtain adequate tissues for histopathological examination and subsequent issue of an accurate pathological report.

Oral Mucosal Injury Caused by Targeted Cancer Therapies

Targeted cancer therapies have fundamentally transformed the treatment of many types of cancers over the past decade, including breast, colorectal, lung, and pancreatic cancers, as well as lymphoma, leukemia, and multiple myeloma. The unique mechanisms of action of these agents have resulted in many patients experiencing enhanced tumor response together with a reduced adverse event profile as well. Toxicities do continue to occur, however, and in selected cases can be clinically challenging to manage. Of particular importance in the context of this monograph is that the pathobiology for oral mucosal lesions caused by targeted cancer therapies has only been preliminarily investigated. There is distinct need for novel basic, translational, and clinical research strategies to enhance design of preventive and therapeutic approaches for patients at risk for development of these lesions. The research modeling can be conceptually enhanced by extrapolating "lessons learned" from selected oral mucosal conditions in patients without cancer as well. This approach may permit determination of the extent to which pathobiology and clinical management are either similar to or uniquely distinct from oral mucosal lesions caused by targeted cancer therapies. Modeling associated with oral mucosal disease in non-oncology patients is thus presented in this context as well. This article addresses this emerging paradigm, with emphasis on current mechanistic modeling and clinical treatment. This approach is in turn designed to foster delineation of new research strategies, with the goal of enhancing cancer patient treatment in the future.

Mucosal manifestations of pemphigus vulgaris in ear, nose, and throat; before and after treatment

BACKGROUND

Pemphigus vulgaris (PV) is a life-threatening autoimmune bullous disease, mediated by autoantibodies directed against antigens on the keratinocyte cell surface of stratified squamous epithelia. The frequency of ear, nose, and throat (ENT) involvement in PV is not clearly identified.

OBJECTIVE

We sought to evaluate the ENT involvement in new patients with PV examined by ENT endoscopy before and after treatment.

METHODS

This study included 41 new patients with PV. All patients were evaluated for ENT manifestations by otoscopic and endoscopic examination before treatment. After these examinations, the patients received proper treatment according to standard protocols. Thirty patients were re-evaluated by endoscopic examination after clinical remission of mucocutaneous signs.

RESULTS

A total of 41 (33 [80.5%] male and 8 [19.5%] female) patients with mean age of 44.56 ± 12.76 years entered this study. In ENT examination of patients before the treatment, 11 (26.8%) patients showed ear, 15 (36.6%) nasal, 37 (90.3%) oral, 25 (61%) pharyngeal, and 24 (58.5%) laryngeal involvement. Thirty patients underwent the posttreatment ENT examination. We found ear signs in 2 (6.7%), nasal involvement in 1 (3.3%), oral signs in 4 (13.3%), pharyngeal manifestations in 6 (20%), and laryngeal signs in 3 (10%) patients after treatment. The treatment was significantly effective in the improvement of mucosal lesion in different sites (P < .01).

LIMITATION

Eleven patients refused to undergo posttreatment ENT examination.

CONCLUSION

ENT evaluation may be worthwhile to evaluate the disease extension in patients with PV more definitely and exclude other potential etiologies in recalcitrant patients.
