Pseudocarcinomatous Hyperplasia of the Fallopian Tubes which was Associated with Female Genital Tract Tuberculosis Histologically Mimicking Tubal Adenocarcinoma: A Diagnostic Challenge

摘要

The benign proliferative and reactive processes of the fallopian tubes which are a result of female genital tract tuberculosis can mimick malignant neoplasms, both clinically and pathologically. ‘Pseudocarcinomatous hyperplasia’ is a term which is applied to the florid form of epithelial hyperplasia with atypical features, that mimicks tubal adenocarcinoma. It may be encountered in the tuberculous and the non tuberculous forms of chronic salphingitis. We are reporting a case of a 30 years old female who presented to our institute with complaints of vaginal discharge and fever. She underwent panhysterectomy for uterine fibroids. Both her fallopian tubes revealed features of florid atypical epithelial hyperplasia, along with widespread caseating granulomatas. Ziehl Neelsen (ZN) staining of the lesion for acid fast bacilli (AFB) was positive. A diagnosis of pseudocarcinomatous hyperplasia of the fallopian tubes which was associated with female genital tract tuberculosis, which histologically mimicked tubal adenocarcinoma was made, which posed a diagnostic dilemma.
