Giant Presternal Dermoid Cyst: An Adult Case

Epidermal cysts are more common above the shoulder and within the face and scalp. The authors report a case of giant presternal dermoid cyst in a 25 year old man. The case illustrates that dermoid cysts can appear in atypical location. Dermoid cysts should be considered in the differential diagnosis of midsternal lesions regardless of the size and imaging characteristics.Key Words: Dermoid cyst, Presternal chest wall, Thoracic surger

Nécrose pariétale utérine partielle après capitonnage hémostatique au cours d’une hémorragie de la délivrance

L'hémorragie de la délivrance reste la première cause de mortalité dans la majorité des pays y compris le Maroc. Sa prise en charge doit être multidisciplinaire, rapide, avec mise en 'uvre de moyens médicaux et parfois chirurgicaux pour contrôler l'hémorragie. Les techniques de compression ou de cloisonnement utérins ont été peu évaluées mais diffusées rapidement dans le monde entier vu la facilité de leur réalisation; Néanmoins des complications secondaires ont été rapportées dans la littérature dont la nécrose utérine. Nous rapportons le cas d'une patiente de 33ans césarisée à 38 semaines d'aménorrhée pour utérus cicatriciel associé à une grossesse gémellaire avec inertie utérine. Un capitonnage hémostatique a été nécessaire pour contrôler l'hémorragie, l'évolution a été marquée par la survenue d'une nécrose partielle utérine confirmée histologiquement. Nous insistons à travers cette observation et sous la lumière de la revue de la littérature sur la nécessité d'un suivi post opératoire des patientes qui bénéficient de capitonnage hémostatique pour mieux documenter l'efficacité et les complications de cet acte chirurgical qui reste encore sous évalué.Key words: Hémorragie de la délivrance, Atonie utérine, capitonnage utérin, nécrose utérin

A rare neuronal tumor of the cerebellum with myoid features

We report an extremely rare tumor presenting with myoid features in the left cerebellar hemisphere in a 62-year-old man. This tumor consisted of medium to large round cells with focal lipomatous and myoid differentiation. Immunohistochemically, the tumor cells expressed synaptophysin, GFAP (glial fibrillary acidic protein) and focally desmin. From these findings, we concluded that this tumor was a liponeurocytoma with myoid features. To the best of our knowledge, this report constitutes the second described case of liponeurocytoma with myoid differentiation in the cerebellum

Endometrial Stromal Nodule: Report of a Case

Endometrial stromal nodule (ESN) is the least common of the endometrial stromal tumors. They are rare neoplasms which are diagnosed in most instances by light microscopy. Although such nodules are benign, hysterectomy has been considered the treatment of choice to determine the margins of the tumor required for diagnosis and to differentiate it from invasive stromal sarcoma Whose prognosis is totally different. We report a case of a 45 years old woman, with presurgical diagnosis of adnexal mass or uterine tumor. She underwent a total abdominal hysterectomy. Pathologic examination revealed an endometrial stromal nodule. Through this observation, we insist on the fact that the ESNs are rare and benign entities which must be differentiated from the other invasive malignant stromal tumors; this can change the final prognosis

Primary hepatoid carcinoma of the ovary: A case report

Primary hepatoid carcinoma of the ovary (HCO) is a very rare type of high-grade invasive malignant ovarian tumor with hepatic differentiation and production of á-fetoprotein (AFP). We describe a 78-year-old Moroccan woman who presented to our hospital with abdominal distension andpurplish nodules infiltrating the para umbilical skin with weight loss and impairment of her performance status. Excisional biopsy of the paraumbilical nodule revealed a cutaneous localization of moderately   differentiated adenocarcinoma and pelvic ultrasonography noted the presence of a tumoral right adnexal mass. The patient underwent an exploratory laparoscopy which found peritoneal carcinomatosis with pelvic adhesions allowing only a peritoneal biopsy. Diagnosis of primary hepatoid carcinoma of the ovary was established on the basis of classic   histopathologic findings, immunohistochemical staining and marked elevation in serum of á-fetoprotein more than the carbohydrate antigen 125. The patient received 3 cycles of chemotherapy based on Carboplatin and Paclitaxel with disease progression. No second line chemotherapy was given because of the drop of patient's performance status to 3. The patient died one month later

Le mélanome primitif de la muqueuse génitale féminine: à propos de trois observations et revue de littérature

Le mélanome malin primitif de l'appareil génital féminin est une tumeur extrêmement rare. Il est fréquemment observé au niveau de la vulve mais il est rare au niveau du col utérin et du vagin. Il est le plus souvent   diagnostiqué à un stade tardif à l'occasion de métrorragies ou de massetumorale. Son histogénèse a été longtemps débattue. Le diagnostic est anatomo-pathologique avec recours nécessaire à l'étude   immunohistochimique. Sa prise en charge n'est pas codifiée avec plusieurs thérapeutiques proposées notamment dans le mélanome métastatique.Son pronostic est désastreux, associé à un taux élevé de récidives et à une courte survie. Les auteurs présentent trois observations, de  mélanomes primitifs vaginal, vulvaire et cervical, chez trois patientes âgées  respectivement de 70, 65 et 40 ans. Et à travers ces observations, ils mettent en relief les principaux aspects cliniques, histologiques, thérapeutiques de cette entité avec une revue de la littérature

Mélanome endobronchique

Le mélanome malin a un potentiel métastatique important. Les métastases pulmonaires du mélanome sont communes cependant la localisation endobronchique reste rare et pose le problème de son origine primitive ou secondaire. Nous rapportons le cas d’un mélanome pulmonaire qui présente des particularités intéressantes: une lésion cutanée présumée primitive totalement régressive, la présentation radio clinique mimant parfaitement un cancer bronchique primitif, un aspect endoscopique bourgeonnant et grisâtre dont l’étude histologique a permis de poser le diagnostic, une agressivité tumorale avec une extension intracardiaque et bourgeon tumoral intra cavitaire. A travers cette observation, les auteurs étudient les caractéristiques radio-cliniques pouvant distinguer le mélanome pulmonaire primitif du secondaire; la localisation endobronchique avec une revue de la littérature sur les métastases endo bronchiques; le bilan d’extension à entamer en cas de mélanome pulmonaire ainsi que les difficultés thérapeutiques posés par ce type de lésion dont le pronostic reste péjoratif

Impact of intercurrent introduction of steroids on clinical outcomes in advanced non-small-cell lung cancer (Nsclc) patients under immune-checkpoint inhibitors (ici)

Background: Baseline steroids before ICI have been associated with poor outcomes, particularly when introduced due to cancer symptoms. Methods: Retrospective analysis of advanced NSCLC patients treated with ICI. We collected the use of intercurrent steroids (≥10 mg of prednisone-equivalent) within the first eight weeks of ICI. We correlated steroid use with patient outcomes according to the indications. Results: 413 patients received ICI, 299 were steroids-naïve at baseline. A total of 49 patients received intercurrent steroids (16%), of whom 38 for cancer-related symptoms and 11 for other indications, such as immune-related events. Overall, median (m) progression-free survival (PFS) was 1.9 months (mo.) [95% CI, 1.8-2.4] and overall survival (OS) 10 mo. [95% CI, 8.1–12.9]. Intercurrent steroids under ICI correlated with a shorter PFS/OS (1.3 and 2.3 mo. respectively, both p < 0.0001). Intercurrent steroids for cancer-related symptoms correlated with poorest mPFS [1.1 mo.; 95% CI, 0.9–1.5] and mOS [1.9 mo.; 95%CI, 1.5–2.4; p < 0.0001)]. No mOS and mPFS differences were found between cancer-unrelated-steroid group and no-steroid group. Steroid use for cancer-related symptoms was an independent prognostic factor for poor PFS [HR 2.64; 95% CI, 1.2–5.6] and OS [HR 4.53; 95% CI, 1.8–11.1], both p < 0.0001. Conclusion: Intercurrent steroids during ICI had no detrimental prognostic impact if the indication was unrelated to cancer symptoms

Clinicopathological, therapeutic and prognostic features of the triple-negative tumors in moroccan breast cancer patients (experience of Hassan II university hospital in Fez)

<p>Abstract</p> <p>Introduction</p> <p>Triple-negative breast cancer (TNBC) is defined as a group of breast carcinomas that are negative for expression of hormone receptors (ER, PR) and Her2, we can distinguish between two groups: basal-like (ER-, PR-, Her2-, cytokeratin (CK) 5/6+ and/or Her1+) and unclassified subtype (ER-, PR-, Her2-, Her1- and CK5/6-).</p> <p>The aim of this study is to determine the clinicopathological, histological, therapeutic and prognostic features associated with this type of breast cancer.</p> <p>Methods</p> <p>This is a retrospective study of 366 female breast cancer patients, diagnosed between January 2007 and June 2010 at the Department of Pathology. Epidemiological, clinical, histological, therapeutic and evolutive data were analyzed. OS and DFS rates were estimated by Kaplan-Meier analysis and a log-rank test to estimate outcome.</p> <p>Results</p> <p>A total of 64 women were identified as having TNBC (17.5% of all female breast cancer patients), 12.6% were basal-like, 4.9% were unclassified subtype, with a median age of 45 years. The median histological tumor diameter was 4.3 cm. TNBC were most often associated with a high grade, 49.2% grade III (53% for unclassified subtype, 47.6% for basal-like). Vascular invasion was found in 26.6% of cases (22% for unclassified subtype and 28.3% for basal-like). For the lymph node involvement: 51% had positive lymph nodes, and 22.4% had distant metastases. Neoadjuvant chemotherapy was administered to 18% patients with 26% of complete pathologic response; therefore adjuvant chemotherapy was given to 82%. 98% received anthracycline based regimen and only 30% received taxanes.</p> <p>The Kaplan-Meier curves based showed the lowest survival probability at 3-years (49% of OS, and 39% of DFS).</p> <p>Conclusion</p> <p>TNBC is associated with young age, high grade tumors, advanced stage at diagnosis, difference chemo response compared to other subtypes, and shortest survival. Critical to optimal future management is accurate identification of truly triple negative disease, and adequately powered prospective TNBC trials to establish treatment efficacy and define predictive biomarkers.</p
