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. The etiology of these metastases remains inadequately comprehended, rendering their administration very intricate. The oncologist at this institution must possess a comprehensive comprehension of how to effectively oversee the patient's quality of life to guarantee the uninterrupted progression of therapy. This paper is a case study of a 51-year-old male patient who was hospitalized due to a severe dry cough and dysphonia that began two months prior to seeking medical consultation. Gingival hyperplasia was diagnosed during a clinical examination. The diagnosis of LCNET (carcinoma of the lung) was determined after a thorough etiological investigation utilizing gingival samples and pulmonary tissue. The objective of this study was to provide a description of our case, conduct an analysis of the response to therapy, and make a contribution to the current body of research. The purpose was to encourage more investigation into this type of metastasis, aiming to get a deeper comprehension of the mechanisms behind the metastatic spread and assess its predictive significance in future instances.

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. The tumor typically occurs in the anterosuperior mediastinum in males and often has a very slow growth pattern and limited potential for metastasis. And symptoms are not very characteristic, with many patients being asymptomatic and the tumor being discovered incidentally. In this paper, we report the case of a 26-year-old patient admitted for the management of a large anterosuperior mediastinal tumor encasing the vital structures of the mediastinum.

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. We report the case of a 45-year-old female patient with chronic renal failure undergoing hemodialysis, admitted for lobular breast carcinoma with bone and peritoneal metastases. The surgical exploration including a biopsy revealed peritoneal tuberculosis. The focus of this paper is to discuss the diagnostic traps associated with PC in malignant tumors to highlight the importance of pathological evidence in such cases.

Unexpected Metastasis of Primary Colonic Adenocarcinoma: A Case Report and Literature Review.

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. Herein, we present the case of a 36-year-old patient who underwent surgery for colonic adenocarcinoma. Subsequently, the patient presented total hematuria during adjuvant chemotherapy. Cystoscopy and biopsy identified a bladder metastasis. In our discussion, we aim to delve into the distinct characteristics of bladder metastases originating from digestive neoplasms.
