Insights
A rare case of Langerhans cell histiocytosis (LCH) was diagnosed in an inguinal hernia sac. This finding highlights the importance of thorough examination during hernia surgery for unexpected masses.
Area of Science:
- Medical Case Report
- Surgical Pathology
- Oncology
Background:
- Langerhans cell histiocytosis (LCH) is a rare clonal proliferative disorder.
- Inguinal hernias are common surgical conditions, typically involving abdominal contents protruding through the abdominal wall.
- Unexpected masses within hernia sacs are unusual and warrant thorough investigation.
Observation:
- A 64-year-old male presented with a year-long history of an inguinal mass.
- Surgical exploration revealed direct inguinal hernias with enlarged lymph nodes within the hernia sacs.
- Excision of an enlarged lymph node led to the diagnosis of LCH.
Findings:
- Microscopic examination revealed characteristic Langerhans cells.
- Immunohistochemical staining was positive for CD1a and S-100 markers.
- This represents the first reported instance of LCH occurring within an inguinal hernia sac.
Implications:
- This case underscores the potential for rare conditions to manifest in unexpected anatomical locations.
- Early and accurate diagnosis of LCH is crucial for appropriate management.
- A multidisciplinary approach is recommended for optimal detection and treatment of LCH, especially in unusual presentations.
Abstract:
It is unusual that an unexpected mass is encountered within a hernia sac. This report describes a patient diagnosed with Langerhans cell histiocytosis (LCH) after surgery for an inguinal hernia. A 64-year-old male patient presented with inguinal mass over a 1-year period. Direct inguinal hernias were found in both sides, and enlarged lymph nodes were found in both hernia sacs. Laparoscopic totally extraperitoneal repair was done, and one enlarged lymph node within inguinal hernia sac was excised for diagnostic purposes. Microscopic findings showed the distinctive cytologic features of Langerhans cells and immunohistochemical staining are positive for CD1a and S-100. LCH is a rare disorder, and the involvement of the lymph nodes with no other sites of disease is uncommon. To the best of our knowledge, this is the first report of LCH within an inguinal hernia sac. Multidisciplinary approach should be considered to provide better detection and treatment.
