A Case of an Adult-Onset Langerhans Cell Histiocytosis Involving the Temporal Bone / 대한이비인후과학회지

Langerhans cell histiocytosis (LCH) is a rare disease characterized by clonal proliferation of Langerhans cells. The temporal bone is frequently involved in pediatric LCH cases, but there have been few reports of adult LCH with temporal bone involvement. We present a case of adult onset LCH affecting the temporal bone. The diagnosis was made by biopsy, based on histopathologic findings of Langerhans cells. Diagnostic and therapeutic considerations of LCH involving the temporal bone are discussed.

Primary Atrophic Rhinitis with Bilateral Turbinates Agenesis

In this paper, we report a case of bilateral inferior and middle turbinate agenesis, a rare anomaly. A 27-year-old woman presented with nasal obstruction, crust formation, anosmia, and foul odors. Anterior rhinoscopic examination revealed the absence of the middle and inferior turbinates on both sides. The patient had no history of nasal or sinus surgery. She denied over having expelled anything of significance from her nasal cavity. She had no history of infectious disease-including tuberculosis and syphilis, granuolomatous diseases, sarcoids, Wegener's disease, and radiation therapy. There have been few reports on bilateral turbinate agenesis.
