Abstract

Sex-cord stromal tumors (SCSTs) with annular tubules (SCTATs) are a small class of ovarian lesions that possess histologic features of both Sertoli and granulosa cells. Approximately one-third of patients with SCTAT also have Peutz-Jaghers syndreome, which makes these cases...

May 8, 2014  |  Marisa Klancnik, MD; Ivo Gluncic, MD, PhD; Drasko Cikojevic, MD, PhD

Abstract

At their earliest stage, pathologic lesions of the laryngeal epithelium are macroscopically invisible. Ideally, these lesions should be detected before their clinical manifestations appear so that prompt management can be initiated. However, most diagnostic modalities are...
