We report the case of a 51-year-old woman with a painless vulvar mass, well circumscribed on ultrasound. On gross finding, it was a polypoid and bilobed mass, partially encapsulated. On histological examination, it was a proliferation of non-atypical spindle cells with an abundant, myxoid stroma and numerous medium-sized blood vessels. The diagnosis was superficial angiomyxoma. The clinical features do not often lead to the diagnosis of superficial vulvar angiomyxoma. It is based on histological examination and immunohistochemistry is helpful to differentiate it from other myxoid tumors.展开更多
Yolk sac tumors of the ovary are rare entities that account for 2% - 5% of all ovarian tumors.

They represent the second most common histological variant of malignant germ cell tumors of the ovary after dysgerminomas. Yolk sac tumors are most commonly encountered in women in the second and third decades. Microscopically, they are highly polymorphic and can present in a pure form or associated with another contingent of germ cell tumor. We report the case of a 26-year-old woman, who underwent surgery for a large right ovarian tumor rupturing into the peritoneal cavity. The ovarian tumor was revealed by ascites of great abundance and abdomino-pelvic pain. On histological examination, the diagnosis of yolk sac tumor in its pure and polyvesicular vitelline pattern was made. Through this observation, we propose to discuss the anatomoclinical particularities of these tumors by emphasizing the importance of histology for the diagnosis as well as the need of an early and appropriate management.展开更多

The disease can be asymptomatic and discovered incidentally or symptomatic, which is often manifested by abdominal pain and motility disorders (diarrhea, constipation). The clinical presentation can also be alarming with rectal bleeding and obstructive symptoms that may be misinterpreted as a neoplastic process. In this paper, we report the case of a 58-year-old female patient with a previous history of appendicetomy. She presented with persistent abdominal pain, chronic constipation and black colored stools, following Covid-19 infection. The physical examination was unremarkable. Colonoscopy examination found a bulging, non-ulcerated mass, measuring 3.5 cm in greatest dimension, located at the right colic angle. Thoraco-abdomino-pelvic computed tomography was performed and showed right colonic wall thickening and enhanced nodule formation. Furthermore, metastatic localization was not detected. After a multidisciplinary meeting, a laparotomy with right hemicolectomy was performed. Histopathological examination of the surgical specimen revealed nodular lymphoid hyperplasia with CD20+, CD5−, CD10+ and BCL2−phenotype on immunohistochemistry. Besides, lymphocytes in interfollicular area are CD3+ T cells. Patient outcome was favorable after surgery and no additional treatment was necessary. Nodular lymphoid hyperplasia of the colon is a benign process whose endoscopic appearance can sometimes raise suspicion of malignancy. The diagnosis can only be established by histological evaluation. Immunohistochemistry is also essential to confirm the diagnosis and to rule out low-grade lymphoma. Clinical evolution is often favorable. However, endoscopic follow-up is necessary in all cases.展开更多

In this paper, we report the third case of invasive mole described in the Malagasy literature. A 33-year-old woman was referred to the Soavinandriana Hospital, her complaint was persistent vaginal bleeding during 2 months, occurring at 3 months of pregnancy with biological anemia without hemodynamic repercussions. The human chorionic gonadotropin (HCG) level was 385,931 mIU/ml. A haemostasis hysterectomy was performed. Histological examination showed an enlarged uterus and endometrial cavity containing edematous chorionic villi with trophoblastic proliferation invading the myometrium. The diagnosis was an invasive mole, stage I, FIGO score 6. Chemotherapy was prescribed but was not honored. After 45 days of follow-up, the serum βHCG level decreased to 1803 mIU/ml, without clinical symptoms. The patient then lost sight. Persistent vaginal bleeding after pregnancy may be the only clinical symptom of an invasive mole and should raise suspicion. Histological examination establishes the diagnosis. As this is an unusual cause of vaginal bleeding, our case should remind physicians that when faced with this symptom, the possibility of an invasive mole should be considered in order to make an early diagnosis for less aggressive treatment.展开更多

We report a case of lingual lymphangioma in a 2-year-old child, revealed by macroglossia. The radiology suspected the lesion. Anatomopathological examination confirmed the diagnosis of cystic lymphangioma, and determined its characteristics.展开更多
