AbstractTeratoma can be defined as a true neoplasm that contains tissues that either are foreign to the primary site of origin or are histologically diverse and represent more than one of the embryonic germ layers. A 20-year-old female patient presented with chief complaints of swelling in the right upper abdomen since childhood and back pain for the past 4 years. Per abdomen, examination revealed a lump of around 15 cm in size in the right hypochondrial region extending to the epigastric region. Contrast-enhanced computed tomography abdomen revealed a 14.3 × 14.1 × 17.4 cm well-defined heterogeneously hypoattenuating nonenhancing complex cystic mass with focal areas of calcifications and fat attenuation in retroperitoneum. The patient was taken up for exploratory laparotomy and a tumor was found in the retroperitoneum, retrocavally and was excised with due care. Histopathological examination features were suggestive of mature cystic teratoma. The postoperative stay was uneventful.

Paratubal Cyst

A 30-year-old woman (gravida 0) visited our hospital with a complaint of right lower abdominal pain. Transvaginal ultrasonography revealed a 5-cm swollen right ovary, which was suspected to be a mature cystic teratoma. Pelvic examination revealed moderate pain. Contrast-enhanced computed tomography showed a 44-mm cystic mass containing fat and calcified material in the right pelvis. Since torsion was suspected, emergent laparoscopic surgery was performed. Intraoperative findings were a swollen right ovary without torsion or congestion. Two small pedunculated 1- and 2-cm diameter paratubal cysts that grew from almost the same place of the ampulla of the right fallopian tube were observed. The thin stalk of the 1-cm paratubal cyst was entangled around the stalk of the 2-cm paratubal cyst, with its head congested. Through a small abdominal laparoscopic incision, the tumor of the right ovary and the two paratubal cysts were excised. Histopathological examination revealed that the right ovarian tumor was a mature cystic teratoma, and the two paratubal cysts had no malignancy. This case showed that only a 2-cm tumor with congestion caused the acute abdomen.

AbstractThe incidence of abdominal cysts in infants is 1 in 500 to 1 in 1,000 live births. Among the ovarian cysts in infants, serous cystadenoma is extremely rare with only few reported cases in the literature. Here, we report a case of a giant neonatal ovarian serous cystadenoma treated with laparoscopic cystectomy and confirmed by histopathological examination.A 27-year-old delivered a female baby with uneventful caesarean section at full term. The antenatal ultrasonography (USG) in third trimester had showed an abdominal cyst in the left side of the abdomen. Postnatal USG was suggestive of omental cyst. A contrast-enhanced computed tomography scan of the neonate showed a large cyst occupying the entire abdomen. On laparoscopic evaluation, a cystic mass filled with 500 mL of clear yellow fluid was seen in the left pelvic fossa. Left ovary could not be visualized separately. The right ovary, fallopian tubes, and uterus were normal. The entire cyst was removed and sent for histopathological examination. On gross examination, a unilocular cyst measuring 10×8×6.5 cm with a wall thickness of 0.2 cm was noted. On microscopic examination, the histomorphological features were consistent with serous cystadenoma of the ovary. There is a paucity of literature regarding pathological diagnosis of such cases and hence we report one such case.

Hepatic Hemangiomas (HH) are benign tumors of the liver consisting of a blood-filled cavity supplied by the hepatic artery. Most of the HH are asymptomatic and are discovered incidentally during radiological imaging of various unrelated pathology. Typical capillary hemangiomas range from a few millimeters to three centimeters and are unlikely to generate any future symptomatology. However, giant liver hemangiomas (more than 10 cm) are a very rare entity and might become symptomatic, hence requiring prompt intervention. We are reporting this case to make the readers aware of the pitfalls and radiological uncertainties while interpreting vascular lesions of the liver. We reported a case of a 21-year-old female with complaint of awareness of a mass over the right upper abdomen since a period of one year which has been gradually increasing in size. On pre-operative Contrast-Enhanced Computed Tomography, features suggestive of Fibrolamellar variant of Hepatocellular Carcinoma was found which was substantiated by biochemical investigations. However, post-operative histopathological examination revealed a capillary hemangioma.

Case Presentation: A 28-year-old female presented to the emergency department complaining of right lower abdominal pain. A contrast-enhanced computed tomography (CT) was done, which showed a 15-centimeter right adnexal cyst with adjacent “whirlpool sign” concerning for right ovarian torsion. Transvaginal pelvic ultrasound (US) revealed a hemorrhagic cyst in the right adnexa, with duplex Doppler identifying arterial and venous flow in both ovaries. Laparoscopic surgery confirmed right ovarian torsion with an attached cystic mass, and a right salpingo-oophorectomy was performed given the mass was suspicious for malignancy. Discussion: Ultrasound is the test of choice for diagnosis of torsion due to its ability to evaluate anatomy and perfusion. When ovarian pathology is on the patient’s right, appendicitis is high in the differential diagnosis, and CT may be obtained first. Here we describe a case where CT first accurately diagnosed ovarian torsion by demonstrating the whirlpool sign, despite an US that showed arterial flow to the ovary. Future studies should determine whether CT alone is sufficient to diagnose or exclude ovarian torsion.

Primary squamous cell carcinoma (SCC) of the renal parenchyma is a very unusual entity which needs to be differentiated from primary SCC of renal pelvis, SCC from another primary site, and urothelial carcinoma with extensive squamous differentiation. We are most probably describing the second case of primary SCC of the renal parenchyma in a 51-year-old male who presented with heaviness of right upper abdomen with intermittent pain in right flank. Contrast-enhanced computed tomography (CECT) revealed a mass in the right lower pole of the kidney and histopathology following nephrectomy displayed the features of well-differentiated squamous cell carcinoma without urothelial involvement.

Background: Endometriosis mainly affects female pelvic tissues and organs, and the presence of endometriosis in the kidney is extremely rare.Case Presentation: We report a case of a 48-year-old woman who presented with intermittent hematuria. She was found to have a cystic mass on renal ultrasonography, and contrast-enhanced computed tomography (CT) showed slight enhancement of the cystic wall and septa. These findings were indicative of cystic renal tumor. The patient subsequently underwent partial right nephrectomy. Histopathology revealed endometriosis of the right renal parenchyma. The patient recovered well and had no evidence of a recurrent renal mass at the 3 months' follow up.Conclusion: The possibility of renal endometriosis should be considered in a female patient with a cystic renal mass and clinical symptoms related to the menstrual cycle.

Hepatocellular adenomas (HCA) are rare benign tumors of the liver, occurring predominantly in females using oral contraceptives. Our case describes a 66-year-old woman presenting with a palpable mass in her upper abdomen. Contrast-enhanced computed tomography and magnetic resonance imaging showed a large exophytic mass protruding from the caudal border of liver segments IV and V, without visible metastases. Laparoscopic resection of the tumor and gallbladder was performed. Histopathological examination showed a hepatocellular carcinoma with areas of HNF1a-HCA (H-HCA). This case shows that malignant transformation is possible in H-HCA. We present our preoperative decision-making process, as well as the role of imaging techniques in this rare case.

Solitary fibrous tumours are unusual neoplasms that develop from mesenchymal cells, usually originating from the pleura. A pericardial solitary fibrous tumour is an extremely rare occurrence. We report a 64-year-old woman who presented to the hospital with chief complaints of dyspnoea and abdominal distension. Echocardiography and enhanced computed tomography revealed an intrapericardial tumour with local invasion to the right atrium. Histopathological examination of a biopsy specimen showed a patternless distribution of spindle-shaped cells in a collagen stroma, with a high mitosis rate. Immunohistochemistry was positive for vimentin, CD34, and Bcl-2. The final diagnosis was a pericardial malignant solitary fibrous tumour with right atrial invasion. Surgical resection of the tumour was not performed because of its invasion into the myocardium. We systematically reviewed the literature on cardiac solitary fibrous tumours up to 2019.

Introduction. Adrenal myelolipoma is a rare tumor that is benign in nature, usually asymptomatic, unilateral, and nonsecreting. It is composed of variable mixture of mature adipose tissue and hematopoietic elements and develops within the adrenal gland. With the widespread use of cross-sectional imaging modalities such as ultrasonography and computed tomography, the incidental detection of these tumors is increasing in frequency.Case Presentation. We report a case of adrenal myelolipoma in a 63-year-old Kashmiri male, who presented with pain in the right upper abdomen. Physical examination was unremarkable. Ultrasound abdomen showed the presence of a hyperechoic mass in the right suprarenal region with undefined margins. Contrast-enhanced computed tomography (CECT) scan of abdomen revealed a well-defined, round lesion in the right suprarenal region with heterogeneous attenuation suggesting the possibility of myelolipoma. The patient was subjected to right adrenalectomy and his postoperative course was uneventful. The histopathological evaluation of the mass confirmed the initial diagnosis of adrenal myelolipoma.Conclusion. Although mostly discovered as an “incidentaloma”, the diagnosis of adrenal myelolipoma warrants thorough diagnostic study. Imaging techniques such as ultrasonography and CT scans as well as biochemical studies are useful for indicating the best treatment taking into account the size of the mass and possible hormone production. Surgical resection is advocated through extraperitoneal approach as it minimizes postoperative complications and leads to quicker recovery.

Background. Mature cystic teratomas of the fallopian tube are extremely rare and only 54 cases have been reported in the literature. In this paper, we report a mature cystic teratoma of the fallopian tube in a postmenopausal woman and we report the review of literature of tubal cystic teratomas.Case. A 62-year-old, gravida 4 postmenopausal woman presented with pain in the right lower abdominal region for a long time. An 88 × 72 × 95 mm heterogeneous mass which contained calcifications and lipoid components was detected in the right adnexal region by transvaginal ultrasonogram (TV-USG). Serum tumour markers, namely, CA125, CA15-3, and CA19-9, were within normal range. A laparotomy revealed a 9 × 10 cm cystic mass within the fimbrial region in the right fallopian tube, and right salpingoopherectomy was performed consequently. Microscopic examination revealed squamous epithelium with sebaceous glands and hair follicles, and pseudostratified ciliated respiratory epithelium with cartilage and mucous glands. Because the frozen section resulted in a benign dermoid cyst, no further operative procedure was performed. The postoperative follow-up was uneventful and the patient was discharged on the second postoperative day.Conclusion. In cases of undetermined pelvic or abdominal masses, a teratoma of the fallopian tube should be considered.
