Imaging findings of fallopian tube leiomyoma with myxoid degeneration: a case report

Leiomyoma of the fallopian tube found during laparoscopic myomectomy: A case report and review of the literature

Leiomyoma of the fallopian tube is an extremely rare benign tumor of the fallopian tube. Because of the small number of cases, it is difficult to calculate their incidence. In this case report, we report a case of leiomyoma of the fallopian tube detected during laparoscopic myomectomy in a 31-year-old female with occasional pelvic pain. The patient was diagnosed with uterine leiomyoma based on a transvaginal ultrasound scan. She was operated and a 3*3 cm mass in the area of the isthmus of the left fallopian tube was observed. Three uterine leiomyomas and one leiomyoma of the fallopian tube were removed. Ultrasound at 6 months postoperatively showed no abnormality. Hysterosalpingo-contrast-sonography (HyCoSy) at 15 months postoperatively showed bilateral fallopian tubes were unobstructed. For those patients with fertility requirements, some fertility-preserving techniques can be used to allow complete resection of the leiomyoma and avoid tubal damage.

Leiomyoma and leiomyoma cellulare of the fallopian tube: review of the literature and case reports

Introduction

Leiomyoma of the fallopian tube is extremely rare, and its version – leiomyoma cellulare (LC) of the fallopian tube is absolutely unique. Aim of the study was to review literature reports on leiomyomas of the fallopian tubes, and to present cases of leiomyoma and LC of the fallopian tubes in the patients operated on in our ward.

Material and methods

There were fewer than 100 cases of leiomyomas of the fallopian tubes discussed in the literature up to 1993. Case 1. Leiomyoma of the left fallopian tube was detected postoperatively in a 68-year-old patient, G.K., on histopathological examination after laparoscopic total hysterectomy with bilateral adnexa. Case 2. A 56-year-old patient, K.T., with LC of the fallopian tube was qualified for laparoscopy. At operation, the procedure was converted to microlaparotomy due to the tumor size. The adnexa on the right side with the tumor of the fallopian tube were excised, and the left fallopian tube was excised, too. Histopathological microscopy found leiomyoma cellulare partim epithelioides.

Results

In the presented cases, the extent of operation was connected with the clinical picture, and in the case of LC of the right fallopian tube, with intraoperative histopathological findings. In both cases the postoperative course was uneventful.

Conclusions

Diagnosis of leiomyoma and LC of the fallopian tube, like in the other organs of the female genital tract, is possible only due to results of histopathological microscopy.

Pathomorphological features of calcinosis circumscripta in a dog

A 19-month-old male German shepherd dog was presented with a hindlimb footpad mass. The mass was excised and histopathology was performed. Grossly, the cut section of the mass had multiple well-circumscribed nodules with a chalky appearance. Histopathologically, basophilic-stained calcium deposits of various sizes were distributed from dermis to subcutis, surrounded by epithelioid cells, multinucleated giant cells, and reactive fibroblasts. Myxoid metaplasia, calcium deposits in hair follicles, and psammoma-like bodies were also found. These histopathologic observations will greatly help to understand the pathogenesis of calcinosis circumscripta.
