Summary

Vascular transformation of lymph node sinuses, a rare condition, can present as neck swelling. This study highlights two unusual cases in the head and neck region, emphasizing the need for broader diagnostic considerations.

Background:

Vascular transformation of lymph node sinuses (VTLS) is a rare condition where lymph node sinuses convert into capillary-like channels.
This transformation is often associated with fibrosis and typically linked to venous or lymphatic obstruction.
Commonly identified causes of obstruction include tumors, thrombosis, heart failure, surgery, or radiotherapy.

Observation:

This report details two unique cases of VTLS presenting solely as cervical lymphadenopathy.
Unlike typical presentations, no obvious cause for lymphovascular obstruction was identified in these patients.
The head and neck region is an uncommon site for this condition.

Findings:

The study identifies vascular transformation of lymph node sinuses as a potential, albeit rare, cause of isolated cervical lymphadenopathy.

It underscores that VTLS can occur without readily apparent lymphovascular obstruction.

The findings challenge the conventional understanding of VTLS etiology and presentation.

Implications:

These cases suggest that VTLS should be considered in the differential diagnosis of cervical lymphadenopathy, even in the absence of typical risk factors.
Further research may elucidate less common mechanisms contributing to VTLS.
Accurate diagnosis is crucial for appropriate patient management and to avoid misinterpretation as malignancy.
