A Case of Alveolar Rhabdomyosarcoma of the Nasal Cavity in an Adult: An Unusual Location.

Rhabdomyosarcoma is a common soft tissue tumor in children but rare in adults. Alveolar rhabdomyosarcoma represents a subtype of rhabdomyosarcoma, extremely rare in adults, especially within the nasal cavities. Therapeutic protocols for adults are often based on those used in pediatric cases.

Cervical Lymph Node Metastasis From Medulloblastoma in a Young Adult: Case Report and Literature Review.

Medulloblastoma, an embryonal tumor located in the posterior fossa of the brain, originates from the neuro-epidermal layer of the cerebellum. It is the most prevalent malignant tumor in children, while it is rare in adults and predominantly affects males. Multimodal therapeutic interventions, such as surgery, radiotherapy, and chemotherapy, have substantially enhanced the prognosis of this condition.

Paraneoplastic Dermatomyositis Revealing the Metastatic Progression of an Undifferentiated Nasopharyngeal Carcinoma: A Case Report From Northern Morocco.

Dermatomyositis (DM) is an inflammatory disease of striated muscles and skin that can occur sporadically or rarely be associated with malignancy, thereby serving as a potential clinical indicator or harbinger of underlying cancer. Knowing the pathognomonic, clinical, and biological features of DM plays a pivotal role in its recognition. Its correlation with nasopharyngeal carcinoma (NPC) is particularly prevalent in regions where the incidence of NPC is notably high, underscoring the intricate interplay between immune dysregulation and oncogenesis.
