Ultrasonography Evaluation of Pelvic Masses

Case Report: Dermoscopic, High-Frequency Ultrasound, Contrast-Enhanced Ultrasound Appearances and Special Treatment of a Patient With Syringoid Eccrine Carcinoma on the Chest

This article aims to explain the use of a variety of noninvasive of minimally invasive examinations to obtain reliable diagnostic clues. The choice of treatment methods and repair techniques for wound defects are also critical in terms of the prognosis. Here, we describe the case of a 53-year-old male patient who visited our dermatology clinic due to a red plaque on the inner side of his left nipple without any symptoms for more than 30 years. He was given dermoscopy, high-frequency ultrasound (HFUS), Color Doppler flow imaging (CDFI), and contrast-enhanced ultrasound (CEUS) examinations. Currently, there are no literatures on these auxiliary examinations for this disease. Dermoscopy revealed that there were abundant blood vessels on the periphery of the skin lesion with obvious dilation. HFUS revealed an inhomegeneous hypoechoic solid mass in the dermis with clear borders and irregular shape. CDFI indicated that there are abundant blood flow signals in the periphery and central of the tumor. CEUS showed a mixed inhomogeneous, grid-like high-enhancement pattern. Based on the above auxiliary findings, the possibility of malignant lesion was suspected. Therefore, the patient was given a pathological examination, which showed that many luminal structures of the dermis layer were embedded in the hyperplastic fibrous tissue. The atypical cells were not obvious but showed an infiltrating growth pattern. Immunohistochemistry showed positive reaction for cytokeratin 7 (CK7), epithelial membrane antigen (EMA), and carcinoembryonic antigen (CEA) and a weak positive results was obtained for S-100. There was also a negative result for CK20, gross cystic disease fluid protein 15 (GCDFP-15), and P63. As a result, the patient was diagnosed with "syringoid eccrine carcinoma." The treatment was surgical excision. Mohs microsurgery was combined with the looped, broad, and deep-buried suturing technique (LBD tension-reduced suturing technique). This technique directly sutures the wound instead of carrying out traditional skin grafting or flap transfer. The postoperative follow-up results were satisfactory as no obvious keloid formed on the wound during the follow-ups. In conclusion, ultrasound is greatly advantageous in tumor morphology and hemodynamics. It orients the therapeutic management and assesses the therapeutic efficacy and the tumoral prognosis. In surgical treatments, a less-traumatic operation should be selected to reduce the patient's pain.

Ultrasonographic features of uterine cervical lesions

Currently, ultrasound (US) is a valuable imaging tool for the initial assessment and evaluation of the female genital organs, uterus, and adnexa. However, it is easy to overlook the uterine cervix while conducting a pelvic US. Uterine cervical lesions may range from benign to malignant in nature. Therefore, meticulous examination with US may play a key role in assessing uterine cervical lesions. Although there is substantial overlap in the US findings across various uterine cervical lesions, some US features, in tandem with clinical characteristics, may suggest a specific diagnosis. Familiarity with the clinical settings and US characteristics of different uterine cervical lesions can support prompt and accurate diagnosis of suspicious lesions. This review article aims to describe the features of US and possible values for distinction of these lesions in the uterine cervix.

The Usefulness of Ultrasound Imaging in Gynecologic Oncology

Pelvic ultrasound examination is the primary imaging modality for evaluating a wide range of female pelvic symptomatology, and is often the first imaging test to detect a gynecologic malignancy. Ultrasound imaging is particularly useful for evaluating the thickness and appearance of the endometrium in patients with abnormal bleeding, and in detecting and characterizing ovarian lesions. This article reviews the ultrasound appearance of gynecologic neoplasms grouped by anatomic site of origin, the ultrasound appearance of select benign pelvic pathology not to be misinterpreted as malignancy, as well as available ultrasound imaging-based guidelines for managing potential gynecologic neoplasms.

Ovarian torsion of mixed epithelial tumor misdiagnosed as a malignancy in postmenopausal woman: A case report

RATIONALE

Adnexal torsion is 1 of the most common emergency gynecological disease. It is more often diagnosed in reproductive age, but rarely in postmenopausal women. The clinical symptoms of adnexal torsion are nonspecific in postmenopausal women. Epithelial ovarian tumors are common in adults, and the risk of malignancy increases with age, especially after menopause. So, it is difficult to diagnose adnexal torsion precisely compared with reproductive women, and most cases of adnexal torsion with postmenopausal women are diagnosed as a malignancy preoperatively. We report a case of ovarian torsion with mixed epithelial tumor misdiagnosed as a malignancy in postmenopausal woman.

PATIENT CONCERNS

A 65-year-old woman presented lower left abdominal pain, and there was slight abdominal distension, but no tenderness or rebound tenderness on abdominal palpation.

DIAGNOSES

Radiologic assessments showed a huge multiseptated cystic mass with solid portion in the left ovary, and malignancy was suspected. The test for serum tumor markers revealed normal levels of cancer antigen 125 (CA-125).

INTERVENTIONS

The patient underwent a laparotomy and there was torsion of the left ovary. We conducted frozen biopsy of left ovary for confirming malignancy before performing staging surgery.

OUTCOMES

The result of a frozen section biopsy confirmed a borderline Brenner tumor associated with a benign mucinous tumor. Subsequently, total hysterectomy and right salpingo-oophorectomy were performed. The operation was completed without addition procedures LESSONS:: Ovarian torsion is benign in most cases and malignancy is rare. Although very rare, ovarian torsion can occur in postmenopausal women, and it should be taken into consideration that the possibility of malignancy is low in postmenopausal women with normal CA-125 levels. Instead of performing staging surgery, it appears to be appropriate to carry out surgery based on the result of intraoperative frozen section biopsy so that we were able to avoid unnecessary surgical procedures.

Occasional finding of giant bladder diverticulum that simulated an ovarian cyst: A case report and literature review

We present a case of a preoperatively unrecognized giant bladder diverticulum in a 63-year-old postmenopausal woman. We carried out preoperative ultrasonographic evaluation and suspected an ovarian cyst. We performed two transvaginal ultrasonography scans before surgery, asking the patient to totally empty her bladder. Consequently, we decided to subject the patient to laparoscopic cyst removal. However, during surgery, the presumed ovarian cyst was not found and a bladder diverticulum was suspected. To confirm our hypothesis, we filled the bladder with saline until the reappearance of giant swelling and we recognized a bladder diverticulum. This case shows that diagnosis based on imaging alone can reveal unpleasant pitfalls. It is important to integrate clinical information, and to consider other possible investigations in order to reduce the chances of a misdiagnosis.

Acute Gynecologic Disorders

Premenopausal women with acute pelvic pain comprise a significant percentage of patients who present to the emergency room. Etiologies can be gynecologic, urologic, gastrointestinal, or vascular. Signs and symptoms are often nonspecific and overlapping. The choice of imaging modality is determined by the clinically suspected differential diagnosis. Ultrasound (US) is the preferred imaging modality for suspected obstetric or gynecologic disorders. CT is more useful when gastrointestinal or urinary tract pathology is likely. MR imaging is rarely used in the emergent setting, except to exclude appendicitis in pregnant women. This article presents a comprehensive review of imaging of acute gynecologic disorders.
