Primary angiosarcoma of the oral cavity is a rare malignant vascular neoplasm variably recapitulating endothelial cells and is generally associated with a worse prognosis. The epithelioid subtype is even uncommon in this localization. To our knowledge, only seven cases of primary oral epithelioid angiosarcoma have been reported until 2021. This histopathological variant is characterized by solid and sheet-like growth patterns that may be misinterpreted as other lesions with epithelioid cells. Herein, we present a new case of primary epithelioid angiosarcoma of the mandibular gingiva to discuss histopathological differential diagnoses and potential diagnostic pitfalls.

Abdominal tuberculosis (TB) remains a significant health concern globally, particularly in regions with high endemicity such as North Africa and Morocco. Despite advances in diagnostic modalities, the nonspecific presentation of abdominal TB poses challenges for timely diagnosis and management. Here, we report a case of abdominal TB in a critically state of a young man from Morocco, presenting with acute abdominal pain and signs of sepsis. Radiological investigations revealed features suggestive of intestinal perforation complicating peritoneal TB. Urgent laparotomy confirmed the diagnosis, yet the patient succumbed to advanced sepsis postoperatively. This case underscores the complexity of abdominal TB diagnosis and management, necessitating a high index of suspicion and multidisciplinary collaboration. With evolving surgical techniques and ongoing research efforts, optimizing strategies for early detection and treatment of abdominal TB remains imperative, particularly in endemic regions.

Uncommon in nature, retroperitoneal ganglioneuroma represents a neuroblastic benign tumor, predominantly manifesting in young adults, with a notable predilection for females. Often asymptomatic, the condition is frequently diagnosed incidentally due to delayed growth. Clinical manifestations arise primarily from the compression exerted on neighboring organs and vessels. The exclusive curative recourse lies in surgical intervention, underscoring the challenging task of achieving complete tumor excision, particularly when the ganglioneuroma attains considerable development and encapsulates significant retroperitoneal vessels. In this instance, we elucidate a case involving a 33-year-old woman, who had previously undergone a triple valve replacement due to rheumatic valvular disease, presenting persistent pelvic pain, unearthing a substantial asymptomatic retroperitoneal ganglioneuroma concomitant with an ovarian endometrioma. A laparotomy procedure was conducted, and to achieve a comprehensive excision of the mass, a meticulous intratumoral circular dissection of the prominent vessels, notably the superior mesenteric artery and celiac trunk, was undertaken. No local recurrence has been reported, 6 months after surgery. The significance of an experienced and well-trained surgical staff is underscored in addressing the complexities associated with this condition.

The Buschke-Lowenstein Tumor is a giant condyloma acuminatum caused by human papillomavirus, most commonly types 6 or 11. It is a rare condition with an estimated frequency of 0.1% in the general population. Transmission primarily occurs through sexual contact. It particularly affects men, predominantly appearing on the penis, characterized by its deep-seated growth, potential for degeneration, and tendency to recur after treatment. Surgery is the preferred treatment. We present the case of a50-year-old patient with a history of recurrent urethritis and multiple sexual partners. The patient sought medical attention for a swelling on the penis that had been progressively developing over the past 10 years. An MRI was performed for a locoregional study, revealing a perineal and penile mass with polylobed contours resembling a cauliflower, along with a sizable perineal mass Histological examination of a biopsy sample from the penis confirmed the diagnosis. Unfortunately, due to the tumor’s characteristics and the patient’s condition, surgery was contraindicated.

Background: Leiomyosarcoma originating from the renal vein (RVLMS) is extremely rare. Only few cases are reported in the literature. Case Report: We report here an exceptional case of a huge LMS of the right renal vein incidentally discovered, occurring in a 73-year-old female patient. Conclusions: This tumor lacks specific clinical manifestations and specific imaging features. Only pathological features make their diagnosis. Standard treatment consists of radical nephrectomy followed by chemotherapy and/or radiotherapy. The prognosis factors are not well identified. Overall prognosis of renal vein LMS is poor

Pseudomyogenic hemangioendothelioma (PMHE) is a rare vascular neoplasm with an intermediate to low-grade malignant potential. Only 5% of PMHEs occur in the head and neck. This tumor exhibits different histological patterns and mimics other vascular tumors, myoid tumors, or carcinomas. The distinction between these tumors can be a very challenging situation for pathologists. In this article, we report the first case, to our knowledge, of PMHE arising in the maxillary sinus, to highlight this uncommon entity and discuss differential diagnoses.

Eosinophilic gastroenteritis is a rare disease with an unknown cause, which can manifest independently or as part of a hyper-eosinophilic syndrome. The severity of the condition depends on the extent of eosinophilic infiltration and damage to the digestive tract. Diagnosis relies on histological examination, which reveals a significant presence of eosinophilic polymorphonuclear leukocytes in the digestive wall. The authors present a new case of eosinophilic gastroenteritis in a 28-year-old patient who exhibited obstructive symptoms but lacked peripheral eosinophilia. Esophagogastroduodenoscopy showed no abnormalities, but barium transit imaging revealed gastro-duodeno-jejunal dilation upstream of a tight jejunal stenosis. Surgical examination of the affected area confirmed a diffuse and transparietal eosinophilic infiltrate, with no evidence of parasitic or granulomatous lesions. Fortunately, the patient had a swift recovery following surgery. Biopsies conducted at other locations, including the gastric, hepatic, and medullary levels, produced negative results, indicating the localized nature of the condition.

Introduction: Myelolipomas were first described in 1905 as an adrenal tumor composed of mature fat mixed with myeloid and erythroid cells. Adrenal myelolipomas are the second most common benign type of tumor in the adrenals, following after adrenocortical adenomas. It is mostly discovered incidentally on imaging of abdomen done for non-adrenal related reasons or at autopsy. Symptomatic tumors, growing tumors or tumors larger than 10 cm should be excised surgically. We report the case of 1 male patient presenting with flank pain and upper pole renal masse, treated surgically with adrenalectomy. Myelolipoma was confirmed on histology. Case presentation: a 46-years-old male, with a history of blood hypertension, presented with persistent abdominal discomfort and occasional pain in the right flank region. Physical examination revealed a non-tender palpable mass in the right upper quadrant of the abdomen. The abdominal CT scan revealed a large well-defined retroperitoneal tumor, which compressed and displaced the right kidney downward, the mass was heterogeneous with areas of soft-tissue attenuation. The patient underwent open left adrenalectomy. The pathological study confirmed the diagnosis of adrenal myelolipoma. The differential diagnosis of fat-containing retroperitoneal masses would include retroperitoneal lipoma or liposarcoma and renal angiomyolipoma. Discussion: Adrenal myelolipomas are the second most common adrenal incidentalomas comprising 6 to 16% of adrenal incidentalomas. The size of adrenal myelolipomas is variable and can range from a few millimeters to greater than 10 cm. These are called giant adrenal myelolipomas. The largest adrenal myelolipoma reported to date weighed 6 kg. Extra-adrenal sites for myelolipomas include the retroperitoneum, thorax, and pelvis. Usually unilateral however they can also involve both adrenals. The most common symptoms observed are abdominal discomfort/pain, hypochondrial pain, and flank pain. Ultrasonography (USG), ......
... Central nervous system melanomas have previously been reported in cats but only as directly invasive ocular lesions or distant spinal metastases [3]. In humans, the CNS can be affected by various melanocytic lesions ranging from benign melanocytomas to malignant metastatic melanomas [4]. Rarely, the intracranial presence of melanin is associated with primary leptomeningeal melanoma either as a type diffusely invading the pia matter and spreading into the subarachnoid space or as a type forming nodular tumours [4,5]. ...

... The MD results were analyzed using (1) protein RMSD that measures the conformational changes of given complex over time and describes whether the simulation is in equilibrium ( Figure 4A) and (2) protein root mean square fluctuation (P-RMSF) that characterizes local changes along the protein chain ( Figure 4B). 30,31 A gradual increase in the RMSD fluctuations for all systems was observed during the initial 2 ns of the simulations. Subsequently, the systems started to stabilize around 4Å after ...

... They usually occur in the context of long-standing multinodular goiters [81,82], mainly in the alpine region although they have been described elsewhere [83,84]. While some authors have considered them as an anaplastic or undifferentiated carcinoma with angiomatoid characteristics [85][86][87], there is now broad consensus that angiosarcomas arise from endothelial cells, characterized by positivity for the CD31 marker and erythroblast transformation-specific related gene (ERG) [77,85,[88][89][90]. Clinical and radiological features are nonspecific. ...

... The most common site of HAC is the stomach, accounting for 63% of all cases, while HAL has an extremely low incidence, accounting for 5% of HAC cases. 7 HAL is indicated mainly by imaging that shows inhomogeneous masses in the upper lung fields; enhanced CT scans reveal homogeneous or heterogeneous density. 5, 8,9 Thus, HAL is difficult to distinguish from other malignant tumours in the lung by imaging alone. ...

... Both tumours have similar clinical, radiographic and pathological features (4). Only the absence of an epithelial contingent on morphological examination and the absence of cytokeratin expression on immunohistochemical examination can formally rule out a sarcomatoid carcinoma of the kidney (10,11). Primary monophasic synovial sarcoma of the kidney also shows monophasic spindle cells. ...

... [1] Because of its scarcity and non-specific presentation, the preoperative diagnosis might be challenging and may be confused with renal tumors . [2,3] Diagnostic workup should include ultrasonography, CT, and/or MRI, but final diagnosis is obtained after a pathohistological examination has been performed. [4] The prevalence of leiomyomas is up to 20-30% among women older that 35 years.Another study have discovered increases of myoma prevalence in older age, almost 70% among >40 years old, with most incidences in African ethnic at >80% of all population. ...
