Pseudoxanthomatous salpingitis: An uncommon lesion of the fallopian tube
Abstract
Pseudoxanthomatous salpingitis (PXS) is an uncommon condition characterized by the presence of pigment-laden histiocytes within the lamina propria of the fallopian tube. Less than 30 cases of PXS have been reported in the literature. We herein report a case of PXS associated with an endometriotic cyst.
1 CLINICAL IMAGE
A 49-year-old woman gravida 4 para 4, presented with a two-month history of pelvic pain. Physical examination did not disclose pelvic tenderness or palpable masses. Pelvic ultrasound examination showed fluid-filled dilatation of the left fallopian tube and a bilocular heterogeneous cyst of the left ovary measuring 4.3 × 4.9 cm (Figure 1A). The patient underwent left salpingo-oophorectomy. Grossly, the ovarian cyst was filled with brown material and the fallopian tube was dilated. Histologically, we noted the presence in the lamina propria of the fallopian tube of numerous pigmented histiocytes (Figure 1B–D). Their cytoplasm was filled with coarse cytoplasmic granules of hemosiderin appearance.1 There were a few foamy histiocytes with vacuolated cytoplasm. Some lymphocytes were intermingled with the histiocytes. The ovarian cyst was lined by an endometrial epithelium with underlying endometrial stroma.1 The latter contained aggregates of pigmented or hemosiderin-laden histiocytes (Figure 2A, B). The final pathological diagnosis was PXS associated with an endometriotic cyst. The postoperative course was uneventful. Currently, the patient is monitored on an outpatient basis with a follow-up period of 2 months.
