Metastatic Sarcomatoid Carcinoma of the Larynx: A Case Report.

Laryngeal spindle cell carcinoma (SpCC) is a unique and very aggressive form of laryngeal cancer. This neoplasm, consisting of malignant epithelial and mesenchymal elements, presents major diagnostic challenges, and there is a lack of conventional therapeutic approaches due to its rarity. This report describes a case of a 53-year-old female who experienced persistent difficulty speaking and a dry cough after contracting coronavirus disease 2019 (COVID-19).

Primary Anorectal Mucosal Melanoma: A Unique Presentation of Mucosal Melanomas.

Anorectal mucosal melanoma (AMM) is a rare and highly aggressive malignancy. It frequently presents with nonspecific symptoms, often resulting in delayed diagnosis and poor prognosis. This report describes the case of a 60-year-old male who presented with a painful para-anal papule that progressed to a fistula.

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.

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.
