# Tuberculous Trochanteritis: An Uncommon Presentation of Primary Tuberculosis Without Articular or Systemic Involvement

## TL;DR

This paper describes a rare case of tuberculous trochanteritis, a form of tuberculosis affecting the hip bone without spreading to joints or the whole body.

## Contribution

The novelty lies in presenting an uncommon primary tuberculosis case localized to the trochanteric region without articular or systemic involvement.

## Key findings

- A mass over the left greater trochanter was found with calcifications and soft tissue collection.
- Histopathological analysis confirmed a tuberculous infection despite negative PCR for Mycobacterium tuberculosis DNA.
- Surgical drainage and resection were performed as part of the management.

## Abstract

This paper reports the experience of our orthopedic department with a case involving a mass over the left greater trochanter that had been developing over nine months. Radiological evaluation (standard radiography + MRI of the left hip) revealed a soft tissue collection over the left greater trochanter with multiple calcifications originating from the trochanteric region. Management included surgical drainage of the collection, resection of calcifications, and collection of samples for bacteriological analysis (PCR for Mycobacterium tuberculosis DNA, which was negative) and histopathological examination. The histopathological findings confirmed a tuberculous infection, leading to the diagnosis of tuberculous trochanteritis.
