The Use of Pneumocystography for Navigation of Stereotaxic Core-needle Biopsy in Complex Breast Cysts: Case Report.

Complex breast cysts (CBC) are characterized by a high (up to 31.0%) oncological potential and the need for a biopsy. In some clinical situations, navigating a biopsy using mammography (MG), ultrasound (US), endoscopy, and magnetic resonance imaging (MRI) may be difficult. The first case of stereotaxic core-needle biopsy (sCNB) under pneumocystography (PCG) guide is presented.

A Canal of Nuck Cyst Presented as a Femoral Hernia: A Rare Case Report With Diagnostic Dilemma.

A cyst of the canal of Nuck is an uncommon disorder in females. It results from the failure of obliteration of the peritoneal fold that runs along the round ligament. This case report details a unique and rare presentation of a 38-year-old female who presented with a right groin swelling. Although her preoperative images showed only the right canal of the Nuck cyst, the intraoperative diagnosis was established as a femoral hernia containing a canal of the Nuck cyst. She underwent an elective cyst excision with repair of the femoral hernia. She had an uneventful post-operative recovery. A femoral hernia that contains a cyst of the canal of Nuck is a rare manifestation of this uncommon condition. The most effective treatment options are surgical cyst excision and repair of the femoral hernia.

Cistoadenofibroma seroso de ovario: experiencia de 12 años en el Hospital General Universitario de Albacete / Ovarian serous cystadenofibroma: 12-year experience at the Hospital General Universitario de Albacete

ANTECEDENTES: El cistoadenofibroma seroso de ovario es una neoplasia epitelial benigna, relativamente infrecuente, de crecimiento lento y de causa desconocida. El diagnóstico preoperatorio es complejo debido a la ausencia de síntomas y signos específicos que permitan descartar la malignidad. OBJETIVO: Analizar retrospectivamente las características clínicas, radiológicas, histopatológicas, y la atención médica de las pacientes. MATERIALES Y MÉTODOS: Análisis retrospectivo y descriptivo de pacientes con diagnóstico histopatológico de cistoadenofibroma seroso de ovario atendidas en el Hospital General de Albacete entre los años 2010 a 2022. RESULTADOS: Se analizaron 635 piezas quirúrgicas, de las que el 57.74% correspondieron a neoplasias serosas benignas, el 17.41% a neoplasias serosas fronterizas y un 24.85% a neoplasias serosas malignas. Se identificaron 20 casos de pacientes con diagnóstico de cistoadenofibroma seroso de ovario. La edad media de esas pacientes fue de 47 años, con límites de 9 y 74 años. Un caso se asoció con un tumor proliferativo seroso atípico contralateral. El tratamiento fue quirúrgico y no se identificaron recurrencias en ninguno de los casos. CONCLUSIONES: El cistoadenofibroma seroso suele manifestarse como un quiste ovárico complejo, con componentes sólidos-quísticos y tabiques irregulares; por esto a menudo se diagnostica erróneamente como tumor maligno antes de la intervención. La biopsia por congelación ayuda a confirmar su naturaleza benigna y evita una cirugía extensa innecesaria. El tratamiento consiste, principalmente, en la extirpación quirúrgica del quiste con o sin ooforectomía. El pronóstico suele ser excelente.

Abstract BACKGROUND: Serous ovarian cystoadenofibroma is a relatively rare, slow-growing, benign epithelial neoplasm of unknown cause. Preoperative diagnosis is complex due to the absence of specific symptoms and signs to rule out malignancy. OBJECTIVE: To retrospectively analyze the clinical, radiologic, histopathologic features, and medical care of the patients. MATERIALS AND METHODS: Retrospective and descriptive analysis of patients with histopathological diagnosis of ovarian serous cystoadenofibroma attended at the General Hospital of Albacete between the years 2010 to 2022. RESULTS: 635 surgical specimens were analyzed, of which 57.74% corresponded to benign serous neoplasms, 17.41% to borderline serous neoplasms and 24.85% to malignant serous neoplasms. Twenty cases of patients with a diagnosis of ovarian serous cystoadenofibroma were identified. The mean age of these patients was 47 years, with limits of 9 and 74 years. One case was associated with a contralateral atypical serous proliferative atypical tumor. Treatment was surgical and no recurrences were identified in any of the cases. CONCLUSIONS: Serous cystoadenofibroma usually manifests as a complex ovarian cyst, with solid-cystic components and irregular septa; this is why it is often misdiagnosed as a malignant tumor before surgery. Freeze biopsy helps to confirm its benign nature and avoids unnecessary extensive surgery. Treatment consists mainly of surgical removal of the cyst with or without oophorectomy. The prognosis is usually excellent.

Management of Cystic Conditions.

Cystic conditions are the most common disorder of the breast. Simple cysts are not malignant and do not require intervention. Patients with symptomatic simple cysts can undergo elective aspiration, and typical cyst fluid can be discarded. Bloody fluid should be sent for cytology. Cysts with thick walls, thick septations, or solid components have a risk of malignancy and should undergo biopsy.

Outcomes in Sonographically Categorized Complex Cystic Breast Lesions.

OBJECTIVES: To investigate outcomes of patients with complex cystic breast lesions and to determine malignancy rates for each sonographic category. MATERIAL AND METHODS: A total of 124 women with a mean age of 45 were enrolled in this retrospective study. Complex cysts were classified into four categories according to sonographic findings (thick septa/wall, intramural nodule, solid/cystic ratio) by two radiologists. Size, margin, short-to-long axis ratio, and vascularity were also noted. The relationship between sonographic features and histopathological/follow-up results was evaluated. RESULTS: Of 124 complex cysts, 11 were malignant and 113 were benign. There were 31 with thick septa/wall (category 1), 14 with intramural nodule (category 2), 60 with solid/cystic ratio < 1 (category 3), and 19 with solid/cystic ratio > 1 (category 4). Among 11 malignant tumors, six intraductal papillary carcinomas and three invasive ductal carcinomas were in category 3, whereas one invasive ductal carcinoma was in category 1 and one was in category 4. Most of malignant lesions (9/11, 82%) were in category 3. Most of benign lesions (96/113, 85%) were fibroadenomatoid/fibrocystic changes. The presence of vascularity (96%), irregular margin (94%), and short-to-long axis ratio ≥ 1 (94%) had higher accuracy rates for diagnosis of malignancy. CONCLUSION: The malignancy rate was 8.8% in our study. Besides internal morphological features, other sonographic features should be considered in the evaluation of complex cystic breast lesions. Due to substantial risk of malignancy and the overlapping sonographic features of benign and malignant lesions, tissue sampling of all complex cysts should be performed.

Prevalence of underlying malignancies in complex cysts of the breast.

INTRODUCTION: The management of complex cysts of the breast is an ongoing topic of discussion. The aim of this study was to determine the prevalence of underlying malignancy in radiologically diagnosed complex cysts, and to assess whether watchful waiting could be the preferred method to safely manage complex cysts of the breast. SUBJECTS AND METHODS: A single-center retrospective study was performed between May 2003 and November 2019 in the VieCuri Medical Centre. Women with a radiologically diagnosed complex cyst of the breast were included. Prevalence of underlying malignancy was calculated, as were absolute risk reduction and number needed to treat in order to diagnose malignancy. In addition, patient characteristics were compared to determine characteristics associated with malignancy. RESULTS: Of 78 radiologically diagnosed complex cysts of the breast, five (6,4%) were found to be malignant. The number needed to treat was calculated at 12,8 (absolute riks reduction 0,078). Age (P = 0,003) was associated with malignancy. CONCLUSION: Complex cysts of the breast could be managed more conservatively. Patient characteristics can be used to assess the eligibility for radiological follow-up. This, in turn, would lead to a lower NNT and possibly a decrease in disease burden and healthcare costs.

Serous papillary cystadenofibroma of vulva: A histopathological surprise.

INTRODUCTION: Serous Papillary Cystadenofibromas (SPCAFs) of the vulva is rare. CASE REPORT: We report a case of a 45-year-old female who presented with a painless slow growing mass in the genital region. Examination revealed a 10 × 8 cm swelling from the vulva. USG was suggestive of a complex cystic lesion and MRI showed a low signal intensity lesion on T2W image. She underwent wide local excision and the histopathology was suggestive of a SPCAF. DISCUSSION: Vulval tumors rare- account for 4 % of female genital tract tumors. Mainstay of treatment in cases of SPCAF is wide local excision. Histopathology confirms the diagnosis and is used to rule out malignant transformation. CONCLUSION: These represent uncommon tumors with high degree of heterogeneity which becomes a major challenge and systematic evaluation is crucial for clinical decision-making and patient management.

Complex Solid and Cystic Breast Cancer: A Series of Six Case Reports.

A cyst in the breast containing a thick wall, internal septations, or a solid intracystic component is defined as a complex solid and cystic breast mass. These lesions carry a malignant potential between 23-31% and thus require further evaluation with biopsy [1]. We report six cases in which patients were found to have a complex solid and cystic mass, all of which were proven to be malignant breast cancers of varying etiologies. We also review the literature on malignant etiologies of complex solid and cystic breast masses, including their clinical presentation, work-up, histopathologic and immunochemistry findings, treatment, and prognosis.

Differentiating Cystic Liver Lesions: A Review of Imaging Modalities, Diagnosis and Management.

Hepatic cysts (HCs) are frequently discovered incidentally on abdominal imaging. The prevalence of HCs has been reported as high as 15-18% in the United States. Although most cysts are benign, some are malignant or premalignant. It is important to diagnose cystic lesions in order to properly manage them. Imaging with conventional ultrasound, computed tomography, magnetic resonance imaging, or contrast-enhanced ultrasound can be used to further characterize and diagnose HCs. Ultrasound is typically the first-line imaging modality, whereas more advanced imaging can help narrow down the specific lesion. Contrast-enhanced ultrasound is a newer modality, recently approved in the United States, which offers non-invasive evaluation in real-time. The first step in diagnosis is stratifying risk by differentiating simple and complex cysts. There are several features that can help identify HCs, including septae, mural consistency, calcifications, and quality of cystic fluid. Simple cysts are mainly congenital cysts, but also occur in polycystic liver disease. Complex cysts include mucinous neoplasms, echinococcal cysts, hemorrhagic cysts, cystic hepatocellular carcinoma and other rare lesions. Treatment is indicated in symptomatic cysts or those suspicious for malignant or premalignant features. Treatment modalities include fenestration, aspiration sclerotherapy, or surgical resection.

A Rare Case Report of Bilateral Complex Macrocystic Adrenal Hemorrhage Mimicking Fetal Neuroblastoma.

Fetal and neonatal adrenal glands are large vascular organs, which make them vulnerable to frequent bleeding. Although neonatal adrenal hemorrhage is commonly reported, it is rarely diagnosed on antenatal sonography. We present a rare case of prenatally diagnosed bilateral adrenal hemorrhage, which mimicked antenatal neuroblastoma.

Vacuum-assisted complete excision of solid intraductal/intracystic masses and complex cysts: Is follow-up necessary?

INTRODUCTION: Management of complex cysts and benign intraductal/intracystic masses is controversial. The aim of this study was to determine if the complete removal of the complex cyst lesions with ultrasound-guided vacuum-assisted excision (US-VAE) is sufficient for their safe management when the histological diagnosis obtained at biopsy is benign. SUBJECTS AND METHODS: This is a single institution retrospective study performed on patients who underwent breast biopsy between April 2007 and September 2013. Patients with complete removal of complex cyst lesion of a BIRADS 4 lesion by US-VAE that obtained a benign diagnosis were included. Size, morphology, histological diagnosis, and surgical or imaging follow-up of the lesions were analyzed. RESULTS: During the study period, 131 lesions met the inclusion criteria. Benign papilloma represented 32% (42/131) of the lesions; the remaining lesions had various benign diagnoses. Mean size of the solid mass or the cysts' thickest septum was 7 mm (range, 2-24). Mean imaging follow-up was 34.9 months (24-99 months) in 115 lesions. No recurrence or malignancy in the post-biopsy bed were observed during follow-up. Eleven lesions (8.4%) underwent surgery as follow-up: no cancer was found, but two lesions demonstrated atypia. CONCLUSIONS: Complex cyst lesion image completely excised with US-VAE and with a benign histology at biopsy might not require further imaging follow-up or surgery and a return to routine screening can be safely recommended. In a world where healthcare delivery and accessibility is important, elimination of unnecessary follow-ups is pertinent given its lower cost and lesser social impact.

Xanthogranulomatous Pyelonephritis Can Simulate a Complex Cyst: Case Description and Review of Literature.

Xanthogranulomatous pyelonephritis is a rare and peculiar form of chronic pyelonephritis and is generally associated with renal lithiasis. Its incidence is higher in females. The peculiarity of this disease is that it requires a differential diagnosis, because it can often simulate dramatic pathologic conditions. In fact, in the literature are also described cases in association with squamous cell carcinoma of the kidney The radiologic clinical findings simulate renal masses, sometimes in association with caval thrombus. We describe a case of xanthogranulomatous pyelonephritis with radiologic aspects of a complex cyst of Bosniak class III in a man 40-year old.

Usefulness of contrast-enhanced ultrasonography for intracystic breast tumors: a report of three cases.

Cystic breast lesions are caused by a wide spectrum of breast diseases and can range from simple cysts to malignant tumors. Ultrasonography is a good tool for evaluation of the morphology and vascularity of cystic breast lesions. We report three patients in whom contrast-enhanced ultrasonography (CEUS) was used to evaluate intracystic tumors. One of the three patients was diagnosed with intracystic papilloma. Compared with conventional ultrasonography alone, CEUS more clearly demonstrated that the solid component within the mass was lobulated with a narrow base. The other two patients were diagnosed with intracystic papillary carcinoma, and CEUS clearly revealed the presence of widely elevated solid components within both masses, suggesting malignancy. Therefore, CEUS simplified morphological evaluation by enhancing the solid components within the cystic masses.
