Giant-cell arteritis of the uterus and adnexa

Area of Science:

• Vascular pathology
• Reproductive medicine
• Histopathology

Background:

• Giant-cell arteritis (GCA) is a systemic vasculitis typically affecting large and medium-sized arteries.
• While GCA commonly involves cranial arteries, rare cases have been reported in other locations.
• Internal genitalia involvement in GCA is exceptionally uncommon, with limited case documentation.

Observation:

• This report details the sixth documented case of GCA specifically affecting the female internal genitalia.
• The case involved an excisional biopsy, providing tissue for detailed pathological examination.
• Clinical presentation and patient history are discussed in relation to the pathological findings.

Findings:

• Histological examination revealed that GCA in this anatomical region predominantly affects the outer layers of the blood vessel wall (adventitia).
• The observed pattern suggests a potential link between the disease's localization and the common occurrence of "senile" elastosis in the adventitia of vessels in this area.
• This specific histological characteristic may influence the diagnostic approach and understanding of GCA in gynecological tissues.

Implications:

• Understanding the specific histological patterns of GCA in the female internal genitalia is crucial for accurate diagnosis and management.
• The findings may prompt further research into the pathomechanisms of GCA in unusual locations and the role of vascular aging.
• This case contributes to the limited literature, aiding clinicians in recognizing and treating this rare manifestation of giant-cell arteritis.
