Xanthoma of Fallopian Tube in Young Female- An Uncommon Entity

Xanthomas or xanthelasmas are rare benign tumours characterised by localised lipid deposits within an organ system which can be an important sign of systemic disease. These tumours have a predilection for skin and subcutaneous tissue, the most common visceral site being the Gastrointestinal (GI) tract. Xanthoma in female genital tract is a rare finding and should be considered as a differential diagnosis for abdominal pain in a reproductive age group. This is an unusual case of xanthoma of fallopian tube in a 27- year-old female presenting with lower abdominal pain and Ultrasonography (USG) revealed right hydrosalpinx. The histopathological examination of fallopian tube showed sheets of foamy macrophages with peripherally placed nucleus and abundant vacuolated cytoplasm in the lamina propria which was positive for Cluster of Differentiation 68 (CD68) and negative for Cytokeratins (CK). A final diagnosis of xanthoma of right fallopian tube was made. Fallopian tube xanthomas must be distinguished from xanthogranulomatous salpingitis, which is associated with an inflammatory cell infiltrate, often including giant cells and plasma cells.
