Trichofolliculoma of the external auditory canal: a case report and review of the literature.

Trichofolliculoma is a rare tumor that arises from immature hair follicular tissue. In this report, we present the case of a 51-year-old man with a trichofolliculoma in the left external auditory canal. Uniquely, there was no prior trauma in this patient, despite previous trauma being hypothesized in the etiology of this tumor. The lesion was excised using microsurgical instruments and the tumor was closely adherent to the cartilage of the external auditory canal. Histopathology following excisional biopsy confirmed the diagnosis.

Management of Extruded Porous High-density Polyethylene Implant in the Internal Nasal Valve.

Porous high-density polyethylene (PHDPE) has been used since the 1990s as an alternative to autologous grafts. Implant extrusion is a rare but well-known complication of PHDPE and other alloplastic implants. This article discusses the case of PHDPE implant extrusion in a 69-year-old man with unsuccessful previous alar batten graft placement for internal nasal valve insufficiency. We detail the surgical techniques engaged in removing the implant from the internal nasal valve, postoperative results, and care, and present a histologic study of the removed implants.

Recurrent, oral cavity tumor-like exophytic lesions mimicking neoplastic disease in a patient with history of human papillomavirus-mediated squamous cell carcinoma.

Reactive hyperplasia is a phenomenon responsible for exophytic lesions in the oral cavity, and may appear to be suspicious, especially in patients who have a significant history of malignancy. Here, we present a case of reactive hyperplasia mimicking recurrence in a patient who was previously treated for tonsillar carcinoma. Physicians who commonly see patients with oral lesions, particularly oral surgeons and otolaryngologists, should be cognizant of the unusual presentation of these lesions as they may mimic the physical characteristics of recurrence.
