Summary
Sinus histiocytosis with massive lymphadenopathy (SHML) is a rare disorder affecting lymphoreticular tissues. SHML commonly presents with head and neck manifestations, including cervical lymphadenopathy and upper aerodigestive tract infiltrates.
Area of Science:
- Oncology
- Pathology
- Immunology
Background:
- Sinus histiocytosis with massive lymphadenopathy (SHML) is a rare lymphoreticular disorder.
- Its pathogenesis remains largely unknown.
- The condition is characterized by extranodal lesions and a variable clinical course.
Purpose of the Study:
- To describe the clinical manifestations and common presentations of SHML.
- To highlight the predilection for head and neck involvement in SHML.
Main Methods:
- Review of clinical data from patients diagnosed with SHML.
- Analysis of lesion distribution and patient demographics.
Main Results:
- SHML most frequently affects the head and neck region.
- Cervical lymphadenopathy is observed in 97% of cases.
- Lesional infiltrates are common in the upper aerodigestive tracts, notably the nasal cavity and salivary glands.
Conclusions:
- SHML predominantly manifests in the head and neck.
- Early recognition of these signs is crucial for timely diagnosis and management of SHML.
