# Mid-thoracic Nodular Fasciitis: A Diagnostic Dilemma

## TL;DR

This case report discusses a rare soft tissue tumor that was initially misdiagnosed, leading to complications and emphasizing the need for careful diagnosis.

## Contribution

The paper highlights the diagnostic challenges of nodular fasciitis and the consequences of mismanagement in a clinical setting.

## Key findings

- Nodular fasciitis was misdiagnosed as a sebaceous cyst, leading to iatrogenic complications.
- The case underscores the importance of strict diagnostic protocols for soft tissue lesions.
- Misdiagnosis can significantly worsen patient outcomes and complicate treatment.

## Abstract

Nodular fasciitis (NF) is a rare, benign, yet rapidly proliferative myofibroblastic soft tissue tumor that often mimics malignant lesions and presents significant diagnostic challenges. This case report describes a 16-year-old female whose mid-thoracic mass was initially mismanaged in an emergency setting as a sebaceous cyst. The misdiagnosis and subsequent inappropriate incision and drainage led to an iatrogenic flare-up, exacerbating the patient's condition and complicating her management course. The complexities encountered in this case underscore the critical need for stringent diagnostic protocols and multidisciplinary management to avoid iatrogenic complications and improve clinical outcomes in patients presenting with unusual soft tissue lesions. This report highlights the importance of adhering to established protocols for soft tissue lump evaluation and the potential pitfalls of misdiagnosis.
