Bilateral benign cystic teratoma of ovary concomitant with an occult gall bladder carcinoma in a post-menopausal woman

Mature cystic teratomas are the most common benign germ cell tumours, and commonly seen in the reproductive age group. It rarely occurs in postmenopausal women. We report a case of bilateral dermoid cyst with cholelithiasis and occult gall bladder carcinoma in a postmenopausal woman.

Collision tumor of ovary: a case report on bilateral dermoid cyst with co-existing unilateral mucinous cystadenoma

A collision tumor is the coexistence of two adjacent, but histologically distinct tumors without histological admixture in the same tissue or organ. Such tumors have often been reported in various organs, but location in the ovary is rare. The juxtaposition with dermoid cysts has been reported as comprising approximately 5% of benign mucinous ovarian tumors and rare examples of proliferating mucinous tumors. Authors are reporting a case of collision tumor which included benign mucinous cystadenoma and benign cystic teratoma. The gynecologists and pathologists should be aware of such combination of tumors. The case was diagnosed post-operatively. It is important to correctly diagnose the component of tumor for further management and favourable prognosis. Frozen section intra-operatively plays an important role in diagnosing such tumors.

Rare Benign cystic teratoma in the parotid gland

Introduction. A teratoma is a tumor developed of several different types of tissue, like hair, muscle, teeth or bone. Aim. Mature benign cystic teratomas are very rare in the salivary glands and just few cases were reported. Description of the case. A 13 years old female was presented to our dental clinic of Princes Basma Hospital in Irbid in north of Jordan, with a painless, insidious progressive swelling in left parotid region without any significant family and personal history. Parents were cancer phobic and nervous from the condition of their daughter, they were very confused. There was no pain or any history of trauma. It was present just inferior to left ear cartilage. The mass was of size 3x3cm, non-tender, fixed, soft to firm in consistency, having smooth surface. Conclusion. Teratoma in parotid region is an extremely rare entity. Lack of any pathognomonic feature, it is hard to diagnose preoperatively. Lumpectomy is advisable to remove the mass because the risk of damaging facial nerve in young patients and recurrence is rare. A definitive diagnosis is achieved after the histopathological study. Teratoma should be kept in account while evaluating a case of a soft tissue mass of parotid gland as a differential diagnosis.

Utility of scrape cytology in the diagnosis of ovarian masses

Background: Cytology is a useful adjunct to frozen section for rapid diagnosis of neoplastic pathology. However frozen section facility is available in limited centres. Therefore, we undertook this study to find out role of scrape cytology for diagnosis of ovarian masses.Methods: It is an observational study done in a medical college. One hundred ovarian masses were collected for a period of eighteen months. Cut surface of ovarian masses were scraped with edge of a glass slide. Smears were prepared and stained with H and E stain, examined and a presumptive diagnosis was given. The verification of cytological diagnosis was done by histopathological report. All the data were recorded, tabulated and analyzed with the help of standard statistical methods using Microsoft XL.Results: A total of hundred cases were studied. Left ovary was involved in 38 cases, right ovary in 52 cases and bilateral ovaries in 10 cases. Malignant cases mostly yielded hyper cellular smear. On Chi square test, it was significant with value of less than .001. The overall sensitivity and specificity of scrape cytology in diagnosing ovarian neoplasm, considering HPE as gold standard, are 98% and 78% respectively. In Dysgerminoma, Papillary adenocarcinoma, Mucinous Cystadenoma, Benign cystic teratoma, Granulomatous lesion of ovary, Lymphoma and Mucinous adenocarcinoma, scrape diagnosis corroborated with the histological diagnosis. Notable discrepancy was seen in cases of Endometrioid carcinoma.Conclusions: Scrape cytology can serve as a powerful tool for early diagnosis of ovarian masses in close cooperation of the clinician, radiologist and pathologist. It has a potential for widespread use as knowledge and experience of interpreting cytopathologists increase.

Para vaginal dermoid cyst: a rare occurrence

Dermoid cyst (cystic teratoma) showing well differentiated derivatives of all three germs cell layers is a benign germ cell tumour. Ovaries remain the commonest site. Paravaginal dermoid cyst is a rare occurrence. Pre-operative diagnosis is usually difficult in majority of cases. They constitute less than 4% of all extragonadal teratomas. A 28-year old, P2L2 female presented with paravaginal cyst, 10×10cms, non-tender, soft swelling, cystic in consistency occupying posterior and left part of rectovaginal septum. Trans vaginal excision of cyst under regional anaesthesia done. Cyst was ruptured while excision showing putty material with tuft of hairs. A retrospective diagnosis of mature teratoma/paravaginal dermoid cyst was made on histopathological examination. Paravaginal dermoid cyst, a benign cystic teratoma is a very rare occurrence. Transvaginal excision of dermoid cyst under anaesthesia remains treatment of choice. Retrospective diagnosis on histopathological examination remains confirmatory as it may be missed on sonography if teeth are not present in dermoid cyst.

Histopathological Study of Ovarian Lesions at a Tertiary Health Care Institute

Background: Ovary is the commonest site of neoplastic and nonneoplastic lesion, can present in childhood to postmenopausal age group and accounts for the most prevalent cause of hospital admissions. Aim: This study was done to analyse the frequency of ovarian lesions their histological features in a tertiary health care centre. Materials and Methods: This is a prospective study of 143 ovarian lesions at tertiary care hospital over a period of 3yr. All the relevant data of patients analysed from hospital record file. Results: The total number of ovarian lesions studied during study period was 143 cases, amongst them 110 were non-neoplastic and remaining 33 were neoplastic. The most common non-neoplastic lesion seen was solitary follicular cysts i.e. 77 cases (70%), followed by corpus luteal cysts 14 cases (12.7%). Among the 33 neoplastic ovarian lesions 25(75.7%) cases were benign, 2(6.1%) case was at borderline and 6 (18.2%) cases were malignant. In benign ovarian neoplasm, most commonly seen lesion were serous cystadenoma followed by benign cystic teratoma. In malignant cases, maximum were of serous cystadenocarcinoma, followed by endometrioid carcinoma and 2 cases of sex-cord stromal tumours (fibromas) were observed metastatic tumours. Conclusion: Ovarian lesion possess wide gamut of histology. Specific diagnoses are made on routine gross and histological examination.

Benign cystic teratoma of fallopian tube with shadow cell differentiation – a rare diagnostic entity with review of literature

A 26 year old gravida 2 para 1 presented to obstetrics department at full term with an unremarkable USG. LSCS was performed for CPD. A fimbrial cyst was discovered intra operatively and excised and sent to us for histopathological examination which showed derivatives of all 3 germ cell layers with presence of shadow cells surrounded by basaloid cells and giant cell reaction. Objective was to report a case of mature cystic teratoma of Fallopian tube with shadow cell differentiation.
