Summary
Sarcoidosis can present solely as neck lymph node granulomas without systemic signs, posing diagnostic challenges. Early detection and monitoring are crucial for potential sarcoidosis development.
Area of Science:
- Immunology
- Pathology
- Otolaryngology
Background:
- Sarcoidosis is a systemic granulomatous disease with frequent head and neck involvement, primarily cervical lymphadenopathy.
- Isolated cervical lymphadenopathy due to sarcoidal granuloma presents diagnostic difficulties when systemic manifestations are absent.
Observation:
- A case study of a 39-year-old male with a progressive, sore right neck mass is presented.
- Biopsy revealed non-caseating epithelioid cell granuloma in cervical lymph nodes, with mycobacterial and fungal infections ruled out.
- Thoracic imaging (X-ray, HRCT) showed no abnormalities, and systemic sarcoidosis was not evident.
Findings:
- Cervical lymph node sarcoidal granuloma can occur independently of pulmonary or systemic sarcoidosis.
- Systemic corticosteroid treatment led to clinical symptom improvement.
- No recurrence or systemic sarcoidosis signs were observed during 1.5 years of follow-up.
Implications:
- Isolated cervical lymph node sarcoidosis may indicate early-stage or precursor disease.
- Regular follow-up is essential for patients with unexplained cervical lymph node granulomas.
- This case underscores the importance of considering sarcoidosis in the differential diagnosis of neck masses.
