As an oral lesion,it raises concern because of its clinical appearance,which may mimic exophytic carcinoma,verrucous carcinoma or condyloma acuminatum. Its pathogenesis is related to human papilloma virus but there is controversy regarding its viral origin. We present a case of squamous papilloma presenting as oral lesion along with a review of the literature.展开更多

However, SPs of the external auditory canal(EAC) are rarely reported in the English literature. In this report, we present a 19-year-old female with left EAC SP. The etiology, natural course, diagnosis and management of this disease are discussed, with a brief review of the literature.展开更多

We enrolled patients with SPE or other superficial lesions to investigate four key endoscopic appearances(whitish color, exophytic growth, wart-like shape, and surface vessels) and used narrow band imaging(NBI) to distinguish their differences. These series endoscopic images of each patient were retrospectively reviewed by three experienced endoscopists with no prior access to the images. All lesion specimens obtained by forceps biopsy were fixed in formalin and processed for pathological examination. The following data were collected from patient medical records: gender, age, indications for esophagogastroduodenoscopy, and endoscopic characteristics including lesion location, number, color, size, surface morphology, surrounding mucosa, and surface vessels under NBI. Clinicopathological features were also compared.RESULTS: During the study period, 41 esophageal polypoid lesions from 5698 endoscopic examinations were identified retrospectively. These included 24 patients with pathologically confirmed SPE, 11 patients with squamous hyperplasia, three patients with glycogenic acanthosis, two patients with ectopic sebaceous glands, and one patient with a xanthoma. In the χ2 test, exophytic growth(P = 0.003), a wartlike shape(P < 0.001), and crossing surface vessels under NBI(P = 0.001) were more frequently observed in SPE than in other lesion types. By contrast, there was no significant difference regarding the appearance of a whitish color between SPE and other lesion types(P = 0.872). The most sensitive characteristic was wart-like projections(81.3%) and the most specific was exophytic growth(87.5%). Promising positive predictive values of 84.2%, 80.8%, and 82展开更多

A 75-year-old woman presented with chronic persistent left nasal obstruction and gradual painless non-axial proptosis with loss of vision in the left eye. Computed tomography scan showed an iso-dense lesion filling the frontal, left ethmoidal and sphenoidal sinuses, and the nasal cavity, with extension into the left orbit. She underwent surgical tumor resection with orbital exenteration and histology revealed features of an aggressive hyperkeratotic squamous papilloma arising from the sino-nasal region. Although squamous papillomas have been natively associated with the oral cavity and oropharynx, they present less frequently as sino-nasal tumors with orbital invasion.展开更多
