Uncommon Metastasis of a Large-Cell Neuroendocrine Carcinoma From the Lungs to the Buccal Palatal Region.

The metastasis of a primary lung tumor to the mouth cavity is a rare occurrence. In addition, the occurrence of neuroendocrine bronchial carcinoma with large cells is uncommon. When metastases are not possible to surgically remove, the conventional treatment for large-cell neuroendocrine tumors (LCNET) is still used.

A Rare Case of Retroperitoneal Immature Teratoma in a Young Adult Male: A Case Report From Eastern Morocco.

Teratomas are classified as germ-cell tumors. They occur more frequently in the gonads, but extragonadal localization can also occur. Retroperitoneal teratomas are rare and require multidisciplinary management.

Diagnostic Challenges for Clinicians in Lobular Breast Carcinoma With Peritoneal Carcinomatosis: A Case Report of an Immunocompromised Patient.

Peritoneal carcinomatosis (PC) is a common condition in oncology. The lack of specificity in radiological and clinical characteristics of carcinomatosis makes their etiological diagnosis difficult. Metastatic infiltrating lobular breast cancer with PC is also a common occurrence in daily medical practice.

Colorectal cancer is a common cancer worldwide. The major sites of colorectal cancer metastasis are the liver, lungs, peritoneum, lymph nodes, and bones. However, secondary localization in the bladder is extremely rare.

Malignant Transformation of Reese's Melanosis: A Case of Conjunctival Melanoma and Related Therapeutic Modalities.

Conjunctival melanoma is a rare but aggressive condition that can arise from healthy conjunctiva, pre-existing nevi, or precancerous conditions like Reese's melanosis. This acquired primary conjunctival melanosis can significantly impact an individual's quality of life due to its potential for recurrence and metastasis. Effective treatment typically requires a multidisciplinary approach to optimize outcomes.

Management of Cisplatin-Induced Encephalopathy: A Case Report and Literature Review.

Cisplatin is a cancer therapy drug commonly used. It is well-known for its antineoplastic properties, as well as for its numerous adverse effects, particularly its neurotoxicity. Symptoms associated with a central nervous system injury are unusual but can present a diagnostic challenge.

Uterine Leiomyosarcoma in a 22-Year-Old Young Woman: A Case Report.

Leiomyosarcoma is one of the rarest types of gynecological cancer. It is a relatively rare condition that affects young women. The most frequent symptom of this disease is vaginal bleeding.

Global Landscape of the Attack of Predatory Journals in Oncology.

Purpose: Open-access publishing expanded opportunities to give visibility to research results but was accompanied by the proliferation of predatory journals (PJos) that offer expedited publishing but potentially compromise the integrity of research and peer review. To our knowledge, to date, there is no comprehensive global study on the impact of PJos in the field of oncology.

Materials And Methods: A 29 question-based cross-sectional survey was developed to explore knowledge and practices of predatory publishing and analyzed using descriptive statistics and binary logistic regression.

Synchronous occurrence of primary breast cancer and renal cell carcinoma: A case report and literature review.

Introduction And Importance: Multiple Primary Malignant Neoplasms (MPMNs) are rare and refer to the occurrence of two or more distinct primary cancers with unrelated histopathological features in one patient. MPMNs can be classified as synchronous when tumors appear simultaneously or within six months of each other, and as metachronous when identified six months or more after the initial cancer diagnosis. While breast cancer often co-occurs with other primary cancers such as colorectal, endometrial, and ovarian cancers, the simultaneous presence of invasive lobular breast carcinoma and clear cell renal cancer is rare.

Metastatic Epithelioid Hemangioendothelioma of the Bone: A Case Report and Literature Review.

Epithelioid hemangioendothelioma (EHE) is an extremely rare vascular tumor, which can pose a diagnostic dilemma. It affects women more than men and is mainly found in the liver, lung, and bone. To date, there are no known predisposing factors.

Jaundice and Higher Procalcitonin Level Revealing a Small-Cell Lung Cancer With Pancreatic Metastasis: A Case Report From Eastern Morocco.

Small-cell lung cancer (SCLC) is highly aggressive, with a severe tendency for metastasis. Pancreatic metastasis in SCLC is uncommon, also jaundice as a major symptom of small-cell lung cancer is even rarer. The diagnosis of pancreatic metastasis is a real challenge for the medical team, it relies on both radiological and pathological details.

Primary Mediastinal Dysgerminoma: A Case Report and Literature Review.

Germ cell tumors are malignant tumors that mostly develop in the gonads. Extragonadal localization is rare and may affect the mediastinal and sacrococcygeal regions. Mediastinal seminoma is a malignant germ cell tumor of the mediastinum.

Neck Epithelioid Sarcoma at an Unusual Location Mimicking Lymph Node Metastases of Nasopharyngeal Carcinoma: A Case Report.

Epithelioid sarcoma (ES) is an uncommon soft tissue sarcoma. It is usually located in the extremities and exceptionally in the neck. Its diagnosis constitutes a real challenge which is based on histology and immunohistochemistry staining that must be interpreted with caution given the anatomopathological similarities to other tumors.

A Case Report of Uterine Müllerian Adenosarcoma With Sarcomatous Overgrowth.

Uterine adenosarcoma remains a highly aggressive tumor and is less described in the literature, with an unfavorable prognosis and an increased risk of local and distant recurrence. However, surgery, chemotherapy, and radiotherapy offer local control of the disease, and overall survival remains reduced. We report the case of a 79-year-old patient with stage IIIB uterine adenosarcoma, confirmed by immunohistochemistry and initially diagnosed with postmenopausal metrorrhagia.

A testicular mass found to be a rare testicular adult-type granulosa cell tumor: A case report and literature review.

Antibody-Drug Conjugates: A New Therapeutic Approach for Triple-Negative Breast Cancer.

Triple-negative breast cancer (TNBC) is an aggressive breast cancer subset associated with a worse prognosis and poor response to conventional chemotherapy. Despite recent advances in drug discovery, its management is still a challenge for clinicians, illuminating the unmet need to develop novel treatment approaches. Antibody-drug conjugates (ADC) are innovative oncology drugs that combine the specificity of monoclonal antibodies and the high efficacy of anticancer payloads, to deliver cytotoxic drugs selectively to cancer cells.
