Endometrial stromal tumors with sex cord-like elements: a case report

Endometrial stromal nodules are rare. They represent less than a quarter of endometrial stromal tumors. Clement and Scully described as variants of endometrial stromal nodules two types of tumor ressembling ovarian sex cord tumors. Type I is tumor that resembles focally an ovarian sex cord tumor which can be abbreviated ESTSCLE, or endometrial stromal tumors with sex cord-like elements and type II; uterine tumors with more than 40% sex cord-like differentiation so called UTROSCT for uterine tumor resembling ovarian sex cord tumor. Uterine tumours with sex cord-like differentiation are very rare with only 50 cases reported in the literature so far. The diagnostic is based on microscopic findings. Immunohistochemical tests to elucidate their nature yield variable and polyphenotypic with coexpression of markers of epithelial, myoid and sex cord lineage as well as hormone receptors. We report an additional case of an endometrial stromal tumors with sex cord-like elements in a 48-year-old woman presenting with abnormal mass.Pan African Medical Journal 2013; 14:5

Ectopic molar pregnancy: a case report

The incidence of hydatidiform moles is 1 per 1,000 pregnancies. Ectopic pregnancy occurs in 20 per 1,000 pregnancies. Thus, the incidence of the ectopic molar gestation is very rare. We report a case of tubal molar pregnancy diagnosed at the systematic histology exam of an ectopic pregnancy. We report the case of 32 years old nulliparus women who presented a vaginal bleeding, lower abdominal pain and 6 weeks amenorrhea corresponding to the last menstrual period. At the clinical examination, the arterial pressure was 100/60 mmHG. The gynecological examination was difficult because of lower abdominal pain. Serum gonadotropin activity was 3454 ui/l. Pelvic ultrasound revealed an irregular echogenic mass in the left adnexa. Diagnostic laparoscopy revealed a left-sided unruptured ampullary ectopic pregnancy. A left laparoscopic salpingectomy was performed. The systematic histologic test identified an ectopic partial molar pregnancy, which was confirmed by DNA ploidy image analysis. The patient was followed with weekly quantitative B-hCG titers until three successive B-hCG levels were negative. It is pertinent that clinicians take routine histological examination of tubal specimens in ectopic pregnancy very seriously in order to diagnose cases of ectopic molar gestations early and mount appropriate post treatment surveillance

Myxome odontogène du maxillaire : à propos d’un cas

Introduction. Le myxome odontogène est une variété rare des tumeurs bénignes des maxillaires, dont l’origine serait la portion mésenchymateuse du germe dentaire. Les manifestations cliniques et radiologiques sont variables et non spécifiques et peuvent prêter à confusion avec d’autres lésions radioclaires. Observation. Nous décrivons un cas de myxome odontogène du maxillaire droit très envahissant, observé chez un jeune patient de 16 ans. Cliniquement, l’adolescent présentait une tuméfaction maxillaire droite, indolore et ferme à la palpation. Une TDM du massif facial montrait un processus expansif ostéolytique soufflant le maxillaire droit. Une biopsie a été en faveur d’un myxome odontogène. Discussion. Le diagnostic s‘est basé sur des arguments cliniques, radiologiques et anatomopathologiques. L’agressivité locale du myxome odontogène et son taux élevé de récidive imposent un traitement radical au-delà des limites de la lésion. La perte de substance qui en résulte implique une réparation chirurgicale ou prothétique

Astroblastoma – a rare and challenging tumor: a case report and review of the literature

Abstract Background Astroblastoma is a controversial and an extremely rare central nervous system neoplasm. Although its histogenesis has been clarified recently, controversies exist regarding its cellular origin and validity as a distinct entity. Because of its extreme rarity and because its common features are shared with other glial neoplasms, this tumor is prone to misdiagnosis and remains challenging not only in terms of diagnosis and classification but also in the subsequent management. This case report describes a new case of astroblastoma. It discusses clinical, radiologic, pathological, and therapeutic features and differential diagnosis of this rare neoplasm, with a review of the recent literature. Case presentation We report the case of an 8-year-old Moroccan girl who presented with a 1-year history of epileptic seizure, headache, and decreased visual acuity. Cranial magnetic resonance imaging revealed a right occipito-temporal mass. A tumor resection was performed and histological examination combined with immunohistochemical study confirmed the diagnosis of low-grade astroblastoma. Conclusions Astroblastoma is a very rare primary brain tumor. Its diagnosis is often challenging because of the astroblastic aspects that can be found in astrocytic tumors, in ependymomas, and in non-neuroepithelial tumors. Considerable confusion surrounds its histogenesis and classification. The low incidence rate makes it difficult to conduct studies to examine tumor characteristics

Eccrine carcinoma : a rare cutaneous neoplasm

Abstract Eccrine carcinoma is an extremely rare malignancy of the skin with few well documented cases reported in the literature. It is frequently found on the lower extremities, and it equally affects both sexes in the sixth and seventh decade. In our case, we present a 46- year-old female with a recurring exophytic tumor on the right lower extremity, without local extension. The initial tumor was biopsied, excised and diagnosed as an eccrine carcinoma.

Intracystic papillary carcinoma associated with ductal carcinoma in situ in a male breast: a case report

INTRODUCTION: Intracystic papillary carcinoma represents a small distinctive subgroup of noninvasive breast cancer, accounts for <0.5% of breast malignancies and is extremely rare in men, it was originally reported as a localized non-invasive carcinoma, but is usually associated with ductal carcinoma in situ around the main tumor or invasive carcinoma. CASE PRESENTATION: We report a case of 50-year-old man with intracystic papillary carcinoma in man with ductal carcinoma in situ who underwent a tumorectomy following by a radical Patey intervention (Halsted). CONCLUSION: Nowadays, there is still no clear consensus regarding optimal treatment of intracystic papillary carcinoma. Most papers reinforce the importance of an adequate surgical margin in conservative treatment. Surgeons must pay much attention to the potential for ductal carcinoma in situ around the tumor when selecting the operative procedure
