Leiomyoma of the fallopian tube

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 with Bizarre Nuclei (Symplastic Leiomyoma) in the Paratubal Cyst Wall: Report of a Rare Case

Leiomyoma is a benign mesenchymal tumor that develops from smooth muscle cells. It can present in various histological variants. Leiomyoma with bizarre nuclei is an infrequent variant of uterine smooth muscle neoplasm. It is characterized by focally or diffusely distributed bizarre cells on the background of a typical leiomyoma. These bizarre cells are large, multinucleated, or multilobulated and have an eosinophilic cytoplasm. Even though leiomyomas with bizarre nuclei display benign clinical behavior, their differential diagnosis from leiomyosarcoma can sometimes be difficult. Leiomyoma has been described most commonly in the uterus. There is no case of leiomyoma originating from paratubal cysts described in the literature. In this article, we present a rare case of leiomyoma with bizarre nuclei originating from a paratubal cyst.

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.

Primary adenomyoma of the fallopian tube mimicking tubal malignant tumor

We report a rare case of adenomyoma localized only in the left fallopian tube mimicking tubal malignant tumor. A 45-year-old woman presented with mild pelvic pain, dysmenorrhea and left adnexal mass. Magnetic resonance imaging showed a solid tumor, suspected primary cancer of the fallopian tube, and serum carbohydrate antigen 125 was elevated to 72 U/mL (normal; 0-35). At surgery, the tumor was revealed as a left fallopian tube tumor without torsion. Postoperative histopathology showed that the tumor included bundle-like growing non-atypical leiomyoma cells and ectopic normal endometrium accompanied with endometrial stroma and we diagnosed primary adenomyoma of the left fallopian tube. Adenomyoma localized only in the fallopian tube is a rare entity and it can occur only in the fallopian tube.

A leiomyoma presenting as an exophytic periurethral mass: a case report and review of the literature

Periurethral masses in females are rarely observed, although they can occur anywhere along the genitourinary tract. They may be detected on physical examination or present with symptoms such as vaginal swelling, bladder outlet obstruction, vaginal bleeding, hematuria, or urinary tract infection. We report a sexually inactive, 27-year-old woman with an exophytic, fimbria-like periurethral mass. The benign nature of the lesion was suspected on the basis of the findings of magnetic resonance imaging. Surgical enucleation was performed. The microscopic examination revealed a urethral leiomyoma. Immunohistochemical study confirmed a leiomyoma with positive staining for smooth muscle actin and negative staining for S-100.

[Giant leiomyoma of fallopian tube: a rare aetiology of abdominal tumor]

Leiomyomas of the fallopian tube are extremely rare. They are often managed with autopsy or surgery. We report a revealed case by a voluminous-abdominal mass in a 35-year-old woman. Neither the tomodensitometry nor, even, the laparoscopy did not permit specifying the tubal origin of the tumor. The diagnosis has been finally carried to the laparotomy. An annexectomy had been achieved. The histological examination concluded to a leiomyoma without malignant-cellular atypia.

[Lipoma of the Fallopian tube]

A swollen fallopian tube was found in a 34 years old woman operated for acute abdominal pain. During this operation the fallopian tube together with the appendix were removed. The histological examination identified appendicitis and a lipoma of the fallopian tube.

A Rapidly Growing Paraurethral Myoma with Profuse Bleeding from a Mucosal Vessel: Report of a Case

Paraurethral leiomyoma is rare. This is the first reported case of a woman with a 6 x 7 x 5 cm urethral leiomyoma with profuse vaginal bleeding. The site of bleeding was identified as the anterior vaginal mucosal vein, which we subsequently electrocauterized. Enucleation of the mass was performed smoothly with a Foley catheter to avoid damage to the urethra. Profuse bleeding from a paraurethral myoma is possibly due to increased vascularity and the prolapsed nature of the tumor in this area.

Torsion of a Paraovarian Myoma in a Teenage Woman

Myomas are uncommon in adolescence and very rarely occur outside the uterus. Torsion of a paraovarian myoma in an 18-year-old woman was managed laparoscopically. Awareness of the condition and high index of suspicion are keys to early diagnosis and prompt intervention.
