Sarcoma-like mural nodules in ovarian mucinous cystadenomas - A report of two cases  [cached]
Chakrabarti S,Konar A,Biswas S,Das S
Indian Journal of Medical Sciences , 2005,
Abstract: Sarcoma-like mural nodule is a very rare occurrence in a mucinous tumour of the ovary. Two such nodules having morphologically benign features with osteoclastic giant cells, in the wall of mucinous cystadenoma are described. In addition, these nodules exhibited reactive vascular proliferations. The sarcoma-like nodules are associated with a favourable outcome and must be distinguished from other malignant nodules composed of sarcoma or anaplastic carcinoma that may also occur in the wall of mucinous ovarian tumours.

Abstract: Mural nodules of ovarian mucinous borderline tumors are rare. In this study, we report a case of mural nodules of clear cell carcinoma in an intestinal type mucinous borderline tumor of the ovary. The patient was a 54-years-old woman presented with back and pelvic pain for 3 months. A right-sided multiloculated ovarian mass approximately 20?cm was identified on the CT scan. CA-125 was moderately elevated. She underwent total abdominal hysterectomy with bilateral salpingo-oophorectomy and bilateral pelvic and para-aortic lymphadenectomy. Grossly, the right ovarian mass showed a multiloculated cystic mass with mucinous fluid. There were papillations in the internal surface and two mural nodules were seen. Microscopic examination revealed that the cystic mass was an intestinal type borderline mucinous tumor. The mural nodules showed a classic histology of clear cell carcinoma with tubulocystic and papillary growth patterns. This is an extremely rare case of mural nodules of clear cell carcinoma arising in a mucinous borderline tumor. 1. Introduction Mucinous ovarian tumors were first described in 1809 by Ephraim McDowell [1]. Nowadays, mucinous ovarian tumors represent up to 15% of all ovarian tumors. In the current WHO classifications of ovarian neoplasms, mucinous tumors are classified as surface epithelial-stromal tumors. Primary mucinous ovarian tumors are further classified into benign, borderline, or malignant categories depending on their histologic features [2]. Borderline tumors account for 10% of all the mucinous tumors [3]. Mucinous borderline tumors have been further subclassified as intestinal and endocervical types [3]. Intestinal-type mucinous borderline tumors tend to be more heterogeneous in composition and may contain areas of cystadenoma and noninvasive carcinoma [4]. Endocervical-type mucinous borderline tumors are more closely related to borderline serous tumors [4]. On rare occasions, one or more discrete well-circumscribed mural nodules protrude into the lumen of a cystic ovarian epithelial neoplasm; most commonly occur in mucinous tumors of intestinal type [4]. The nodules may be reactive or neoplastic, and some have mixtures of both types. Mural nodules with foci of anaplastic carcinoma, sarcoma, sarcoma-like, and carcinosarcoma-like nodules have been reported in the literature [5–7]. We hereby report a case of mural nodules of clear cell carcinoma in an intestinal-type borderline mucinous ovarian tumor. Although clear cell carcinomas have been found in association with mucinous cystadenomas and endometriosis in the past [8–10], to

Abstract: Introduction. Cystadenofibromas are tumors of the ovary which originate from the surface coelomic epithelium. Benign mucinous cystadenofibroma is a very rare form of these tumors, which consists of dominant stromal component of the connective tissue and one or more cysts. Case report. The case of a 62-year-old female with tumor of right ovary is reported in this paper. Histologically, tumor of the ovary had multilocular cystic formation, lined by a single-layer of mucoproductive cylindrical epithelium - endocervical type. In one area of tumor, the stromal component was abundant and made from partially hyalinised dense connective tissue. Mucinous cystadenofibroma was diagnosed on the basis of histological examination. Since the mucinous type of cystadenofibroma or adenofibroma is rare, this case has been chosen to be presented. Conclusion. Mucinous cystadenofibromas are differentially- diagnostically very similar to different malignant tumors and it is extremely important to make correct diagnosis of these neoplasms.

Abstract: Introduction: Ovarian cysts are relatively rare in children. Mucinous cystadenomas are rarely encountered in adolescent patients and can reach an enormous size. Mural nodules associated with mucinous tumors of the ovary may represent a benign or malignant process."nCase Presentation: Our case was a 15-year-old female, which referred with a painless abdominal distention gradually appearing during six months. There was no specific symptom only mild discomfort of bowel habits with the regular menstruation. On physical examination, there was complete distention of the abdomen without any tenderness. Ultrasonography revealed a large loculated cystic mass in the abdominopelvic cavity, which contained few septations and mural nodules without any vascularity on color Doppler ultrasonography. All other organs appeared normal. On contrast enhanced CT scan, there was a large intra-peritoneal 280×250×170 mm anteriorly located cystic mass which extended from the upper abdomen down to the lower pelvis displacing and compressing adjacent structures posterolaterally. Multiple enhancing septa and two mural nodules were found in the cystic mass. All solid organs appeared normal and no significant adenopathy or ascitis was detected. According to the above findings, omental cysts, adenexal cysts, urachal cysts, mesenteric cysts were our differential diagnosis. A 10 kg mass was resected (an exophytic cyst in the right ovary) and histopathology revealed mucinous cystic adenoma of the right ovary with fibrotic mural nodules. No recurrence was detected after one year."nDiscussion: Mucinous cystadenomas are rarely encountered in adolescent patients and can reach an enormous size. The interesting point of this case was not only because of its rarity but also because of its unusual symptomless manifestation and also fibrotic mural nodules."nKeywords: Mucinous Cystic Adenoma, Ovary, Adolescence

Abstract: Ovarian adenofibroma is a rare benign tumour originating from the germinal lining and stroma of the ovary. We describe here the case of a 36-year-old woman with an ovarian mucinous cystadenofibroma that was diagnosed as a benign cystic mass of the ovary before surgery. The tumour was a cystic lesion composed of 2 regions: one filled with mucinous fluid and the other with yellowish solid components. The patient successfully underwent a left oophorectomy. 1. Introduction Ovarian cystadenofibroma is a very rare benign tumour that originates in the epithelium and includes diverse structures composed of cystic and solid fibrotic tissues. These tumours are classified, according to the epithelial cell types present, as serous, endometrioid, mucinous, clear cell, and mixed categories. Because ovarian cystadenofibroma presents as a multicystic mass with solid components, preoperative differential diagnosis is important to distinguish it from malignant neoplasms. In this report, we describe the treatment of a 36-year-old woman with an ovarian cyst. The lesion was not diagnosed as a benign tumour before surgery. After surgery, the tumour was diagnosed as a mucinous cystadenofibroma. 2. Case A 35-year-old gravid (1-0-0-1) woman presented with left lower abdominal pain for several years. Her menstrual cycle length was 30 days, menstruation volume was normal, and she experienced slight menstrual pain. Her family history was uneventful. Upon comprehensive medical testing, an ovarian mass was detected by pelvic CT. After the patient was transferred to our hospital, she underwent pelvic MRI. The MRI showed a 6 cm left ovary mass with numerous small cysts and a fibrous septal structure. At the time of admission, the patient’s blood pressure was 140/80?mmHg, her pulse was 74?bpm, her temperature was 36.5°C, and her general condition was good. During a pelvic examination, a painless cystic mass was detected in the left adnexal area. Blood test results were normal: haemoglobin level, 12.9?g/dL; red blood cell volume, 38.7%; leukocyte count, 6.380; and platelet count, 235,000. Results of urinalysis and blood chemistry analysis were within normal ranges. Serum concentrations of the tumour markers CA-125 and CA19-9 were 18.08 and 55.72?ng/mL, respectively; the CA19-9 tumour marker level was slightly elevated compared to normal. Transvaginal sonography performed at our hospital showed that the uterus was deviated to the right; no other notable features were observed, except for the left ovarian tumour, approximately 6 × 6?cm in size, with a septum. The inside of the tumour

Abstract: Cystadenomas of the pancreas are rare single and isolated tumors, usually appearing in young and middle aged women. Thecomas are rare usually unilateral, benign, estradiol, much rarer androgens producing ovarian tumors. We present a 19 year old girl in whom we removed two mucinous cystadenomas of the tail of the pancreas, 7 and 2 cm in diameter as well as a thecoma of the right ovary. As far as we know this combination of tumors have not been reported before.

Abstract: Giant benign tumours of the ovary are rare in the modern world due to the improved technologies and general awareness. They are known to cause pressure symptoms to the surrounding structures. Though they appear frighteningly large, they are amenable to surgical debulking with good results in survival and post operative recovery. Here we would like to present a case where the patient could not access medical care, which led to the presentation of a very large mucinous cystadenoma which responded remarkably to surgical excision. The patient could go back to her normal life following the procedure. Conclusions Giant benign mucinous tumours are a rarely seen in the modern world. They have excellent surgical results and survival rates.

Abstract: Monodermal teratomas of the ovary can take the form of carcinoid tumors of which there are several types, mucinous carcinoid being the least common. Very few cases of primary mucinous carcinoid of the ovary have been reported in the literature and the behavior of these tumors over the long term is unclear. We describe a case of primary mucinous carcinoid of the ovary in a 39-year-old woman treated with unilateral salpingo-oophorectomy, where a metastasis occurred in the contralateral ovary ten years later. This case demonstrates that mucinous carcinoid of the ovary can metastasize even after a long interval, and careful follow-up of patients, particularly those treated conservatively, is appropriate.

Case Reports in Pathology , 2012, DOI: 10.1155/2012/523231
Abstract: This is a case of a 71-year-old woman, who presented with a large abdominal mass. Microscopic examination revealed metastatic renal cell carcinoma in an otherwise massively enlarged benign ovarian tumour of mixed mucinous cystadenoma and Brenner tumour. Clinicopathological and radiological assessment together with a thorough evaluation of gross and histological features, including the use of immunohistochemical stains, is essential to confirm the diagnosis and rule out the possibility of primary clear cell carcinoma of ovary, as this has important prognostic and therapeutic implications.

Abstract: The solitary pulmonary nodule (SPN) is frequently seen on chest radiographs and computed tomography (CT), usually the identification is accidental. The overall prevalence of malignancy is relatively low but identification of malignancy of nodule is of prime importance. There are different characters of nodules indicating malignancy, and also the exposure of person to risk factors increases the chances of malignancy of nodule. Chances of malignancy rise with increasing size, the irregular, lobulated border of the nodules is highly associated with higher probability of malignancy and nodules with pure ground grass appearance have higher probability of malignancy, irregularly marginated nodule displaying a corona radiata sign indicating neoplastic infiltration with distortion of neighbouring tissue is almost certainly a malignant nodule. Stippled, punctuate, and eccentric calcifications are suggestive of malignancy. There are 20% - 75% of chances of malignancy if nodule is appeared with ground-glass opacity. Malignant nodules have higher growth rate as compared with benign nodules, malignant nodules usually have doubling time (DT) of 30 - 400 days while DT of more than 450 days is sign of benignity whereas doubling time less than 30 days is usually acute infectious process. The presence of fat within nodule is sign of benignity. Increasing density of the nodule is suggestive of malignancy and requires shorter follow up. Besides the nodule evaluation the chances of malignancy can also be evaluated through the exposure of patient to risk factors like age, current and past smoking status and history of extra thoracic malignancy. The management depends upon various factors mainly three strategies are applied for management including careful observation of nodule, use of diagnostic techniques like CT FNA, PET, and broncoscopy and surgery.
