Isolated ano-perianal tuberculosis: challenging diagnosis

Abstract

The tuberculosis is a public health issue. The ano-perianal localization is very rare, representing less than 0.7% of the digestive localizations. Basing on personal observation and literature review, we cite the diagnostic difficulties and the epidemic clinical, therapeutic and evolutive particularities of this rare entity. A 34year-old-women was admitted for the exploration of chronic suppuration of the perianal and gluteal region which has been in progress since 10years. Many investigations were made and we retained the diagnosis of ano-perianal tuberculosis localization after detecting the presence of Koch bacillus on Lowenstein Jensen culture of biopsies and stools. The patient was treated with Quadratherapy. Our observation illustrates the difficulties in diagnosing ano-perineal tuberculosis with chronic anal suppuration causing a delayed diagnosis and therapeutic management.
